Bulletin Purpose

3626938

The purpose of this bulletin is to help the Service and Sales Department Personnel become familiar with the all-new
2014 Cadillac CTS Sedan and CTS Vsport Sedan.

About the Vehicle
Cadillac’s all-new 2014 CTS sedan ascends into the heart of the midsize luxury market with expanded performance,
elevated luxury and sophisticated technology. The third-generation CTS is based on the high-performing rear-drive
architecture of the award-winning ATS sport sedan, moving Cadillac into the prestigious class of midsize luxury
sedans. The Cadillac User Experience (CUE) infotainment system is standard, with an available 12.3-inch
high-resolution LCD instrument cluster. Cadillac’s first aluminum door structures contribute to making it the
segment’s lightest car, and a nearly 50/50 weight balance enable the most agile driving dynamics in the class. A
range of power-dense powertrains underpin its performance, including the all-new Cadillac V-6, 3.6L twin turbo
engine coupled with an eight-speed automatic transmission.

A longer, lower and more athletic-looking proportion is introduced on the CTS and evolves the Cadillac brand’s Art &
Science design philosophy. The vehicle has increased by 5 inches (127 mm) in length, including a 1.2 inch (30 mm)
longer wheelbase. The roofline, cowl, and base of the windshield, are about 1 inch (25 mm) lower, and these
dimensions complement the longer exterior and accentuate the car’s lean aesthetic look. The grille is wider with a
more detailed texture, while the headlamps flow up with the hood line, incorporating crystalline LED light guides for
an advanced appearance with more uniform illumination. The CTS is available with segment-exclusive Magnetic
Ride Control and it is standard on all models with 18 inch and 19 inch wheels. The CTS Vsport comes with Magnetic
Ride Control and electronic limited slip differential (ELSD), which constantly monitors rear-wheel rotation from one
side versus the other to ensure optimal handling on a variety of road conditions.
Cadillac engineers applied the principles of psychoacoustics, which is the science of sound perception to create
powerful and pleasant exhaust notes for the CTS and CTS Vsport. Knowing that engine sound communicates
throttle response to the driver, the engineers uniquely tuned each selectable driving mode – Tour, Sport and Track –
to provide the driver with a specific sound impression of what’s happening under the hood. Tour mode purrs with
refinement. Sport mode growls with power. Track mode which is only available on the CTS Vsport, roars even more
aggressively.
The CTS will feature 10 airbags, Ultrasonic Rear Park Assist (URPA) and OnStar® for one year as standard
equipment. There are optional safety features that can be added, including: Full Speed Adaptive Cruise Control
(ACC), Panic Brake Assist, Forward Collision Alert (FCA), Automatic Collision Preparation (ACP) with brake prefill,
Lane Departure Warning (LDW) , Side Blind Zone Alert (SBZA), Rear Cross Traffic Alert (RCTA), Rear Vision
Camera (RVC) with Dynamic Guidelines, Adaptive Forward Lighting (AFL) and Active Pedestrian Protection System
(in global regions where required). Also available for the first time on a Cadillac is automatic seatbelt tightening to
ensure optimal safety and comfort at all times.
Available on the CTS is Automatic Parking Assist, which enables the car to park itself in parallel spaces. It uses
ultrasonic sensors to locate a suitable space and then maneuver the car into the space, with the driver only required
to engage R (Reverse) and apply the accelerator and brake pedals.
Active Aero Grille Shutters are included on some models, improving aerodynamic performance on the highway to
enhance fuel efficiency.
The adaptive remote start feature also activates the climate control system.
The CTS is available with a choice of three powerful and efficient direct-injected engines coupled with a 6-speed
automatic or an 8-speed automatic transmission with standard rear-wheel-drive (RWD) and available all-wheel-drive
(AWD). The new paddle-shift eight-speed transmission offers efficiency and performance advantages over a
six-speed transmission, including a 1.5-percent improvement in fuel economy.

Cadillac Premium Care Maintenance / New Vehicle Limited Warranty
The CTS model comes with the Cadillac Premium Care Maintenance program. It is a program designed to provide
the customer with peace of mind by covering select required maintenance during the first four years or 50,000 miles
(80,000 km) of the vehicle’s operation. It aligns with the terms of our 4-years or 50,000 mile bumper-to-bumper New

Dexos1™ Engine Oil Specification — Recommended Viscosity

3511747

3512027

Only those oils displaying the dexos1™ trademark and a registered trademark logo on the front label of the container
meet the demanding performance requirements and stringent quality standards set forth in the dexos1™
specification.
Look on the front label for either of the logos shown above and the 11 digit alphanumeric dexos® license number on
the back label to identify an authorized, licensed dexos1™ engine oil. Unless an oil package displays these two
markings, the engine oil is not an authentic, licensed dexos® product and is not recommended for use in GM
vehicles.
The dexos1™ specification was uniquely designed to complement the exacting requirements of GM's advanced
engine technology. The specification has gone through an extensive developmental and testing process. It requires
a number of proprietary tests that are not included in current industry standards and sets performance criteria at a
level that exceeds many current standards. The result is a high performance fluid providing significant wear
protection, improved piston cleanliness, a reduction in volatility and oil consumption, enhanced aeration control for
improved fuel efficiency, and better oxidation properties.

Viscosity Grade
Notice: DO NOT use other viscosity grade oils such as SAE 10W-30, 10W-40, or 20W-50.
ACDelco dexos1™ Synthetic Blend SAE 5W-30 is the recommended viscosity grade for the 2.0L turbocharged
engine, 3.6L and 3.6L twin turbocharged engine.
Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −20°F (−29°C), an
SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely
low temperatures.
Refer to this General Motors website for dexos1™ information about the different licensed brands that are currently
available: http://www.gmdexos.com

Low Profile Vehicles — Lifting and Jacking the Vehicle
The use of a LOW PROFILE LIFT ARMS SYSTEM may be required to avoid unwanted contact with the vehicle's
body and structure depending on lifting equipment used. Refer to the hoist manufacture's recommendation for their
applications of low profile lift arms system for their lifting equipment. Before setting or raising the vehicle, refer to
Lifting and Jacking the Vehicle in SI.

Cadillac User Experience (CUE) Infotainment System

3620335

At the core of the car’s intuitive technologies is the Cadillac User Experience (CUE) infotainment system that uses
smartphone and tablet-influenced controls and commands to access information and entertainment data. CUE uses
sharp, metallic icons with an illuminated blue glow on the eight-inch high-resolution color capacitive touch screen
with haptic feedback that allows users to swipe and drag preferences, reconfiguration of Home screen icons, a
Personalized app tray and the ability to save multiple rows of Favorites. Prominent Home screen apps can be
dragged to the top row of the screen, making them easily accessible from a different page or application. The
screen’s bottom row features a Favorites’ bar that stores presets like Navigation Destinations, Phone Contacts and
Radio Stations. Drivers can use their finger to drag this bar up, revealing three more rows of Favorites, or slide the
bar down to hide them. A full-color, configurable head-up display is also available. Bluetooth® connectivity with
natural voice recognition is standard with CUE, along with USB and SD card ports.
The 2014 CTS also serves as Cadillac’s first implementation of Apple’s Siri Eyes Free mode. Users with
Siri-equipped iPhones can connect their devices to CUE via USB or Bluetooth® and tap the voice control button on
the steering wheel to activate Siri. The software is a slightly augmented version of the digital assistant, stripping out
things that could lead users to take their eyes off of the road, such as Web searches.
CUE comes standard with the Bose® eleven speaker sound system and the available Bose® Centerpoint®
Surround Sound system with 13 speakers. Bose® Active Noise Cancellation is included on all models. This
technology reduces the unwanted low frequencies created by the engine, transmission and other powertrain
components by up to 20 dB, resulting in a quieter in-cabin experience.

5.7-Inch Full Color Configurable Driver Information Center / 12.3-Inch
High-Resolution Configurable LCD Instrument Cluster

3623914

Standard on all models except Premium Collection is a 5.7-inch full color configurable driver information center
(DIC), allowing the driver to select information to display.

3620555

Standard on Premium and available on Performance Collection is the 12.3-inch high-resolution, configurable LCD
instrument cluster display complements the CUE display and supports the active safety features. It offers drivers four
different layouts each delivering bold, crisp graphics tailored to the level of vehicle information desired as follows:
– Balanced: A traditional setting with a three-gauge layout, which is the factory default setting.
– Simple: A digital appearance, limiting the amount of information displayed.
– Enhanced: A modern look with a large digital speedometer in the center. This view displays the maximum amount
of information.
– Performance: A performance-oriented, sporty display, with a 3D rotating view of the vehicle.

Cleaning High Gloss Surfaces, Vehicle Information Displays and Radio Displays

2873573

Notice: The microfiber cloth is shipped in the bag that contains any loose items that are to be installed
when performing the vehicle PDI.
The CTS has high gloss surfaces, vehicle information displays and radio displays. Use a microfiber cloth to wipe
these types of surfaces. Before wiping the surface with the microfiber cloth, use a soft bristle brush to remove dirt
that could scratch the surface. Then use the microfiber cloth by gently rubbing to clean. DO NOT use window
cleaners or solvents. Periodically hand wash the microfiber cloth separately from other items, using mild soap. DO
NOT use bleach or fabric softener. Rinse thoroughly and air dry before the next use.

Engine and Transmission
The CTS is available with a choice of three powerful and efficient engines coupled with a 6-speed automatic or an
8-speed automatic transmission. The available engines, transmissions and specifications are as follows:

2904426

Cutaway of Twin Turbo V6 3.6L RPO LF3
The Cadillac Twin Turbo is the most power dense six-cylinder engine in the segment. A pair of smaller turbochargers
provide more immediate power on demand, with approximately 90 percent of torque available in the 2,500 RPM to
5,500 RPM range. That gives the engine a broad torque curve that will feel as strong, willing power in almost all
driving conditions.

3620440

1. Integrated Charge Air Cooler (Intercooler)
2. Charged Air
3. Exhaust Gases
4. Intake Air
The industry’s first integrated charge air cooler (1) configuration puts the two small turbocharger air paths and
related cooling bricks into the intake plenum. This advanced design provides the following:
• Dramatically reduces the distance compressed air travels from the compressor to the intake plenum to virtually
eliminate turbo lag.
• Underhood packaging benefits.
• Significantly improves noise, vibration and harshness performance by reducing air-rush noise and ductwork
resonance.
The vacuum-actuated wastegate control provides smoother, more consistent performance across the RPM band,
reduces engine noise and increases engine durability.

Cutaway of 8-Speed Automatic Transmission

3619197

New to Cadillac is the AISIN TL- 80SN 8-Speed Automatic Transmission — RPO MGG

88863400 and in Canada P/N 88863401

Brembo Performance Front Aluminum Brake Calipers / DURALIFE™ Brake Rotors
Standard on all models, these Brembo performance front aluminum brake calipers have these features:
• Lighter weight reduces the unsprung weight for enhanced steering and handling.
• Stiffer calipers reduce brake wear and offer superior braking performance.
All DURALIFE™ brake rotors are vented to dissipate heat. A ferritic nitro carburizing (FNC) treatment makes the
DURALIFE™ brake rotors corrosion resistant. This manufacturing process provides the following benefits:
• Rotors stay shiny and new looking.
• Eliminate brake shudder caused by corrosion buildup.
• Reduce brake dust accumulation.
• Virtually double rotor service life.
Front brake rotors are 12.6 inches (320 mm) on the 2.0L and 3.6L and 13.6 inches (345 mm) on the 3.6L Twin Turbo
Vsport.
Rear brake rotors are 12.4 inches (315 mm) on all models.

Magnetic Ride Control / Front and Rear Suspension
Magnetic Ride Control

2899749

Depending on the equipment package the vehicle may be equipped with Magnetic Ride Control — the fastest
reacting suspension in the world. Magnetic Ride Control delivers precise body motion control by electronically
monitoring the road conditions every millisecond and reacting by changing shock absorber damping in as little as
one to five milliseconds. The electronically controlled front and rear shocks are filled with a magneto-rheological fluid
containing minute iron particles. Under the presence of a magnetic charge, the iron particles align to provide
damping resistance almost instantly.
Front Independent Multi-Link MacPherson Strut Suspension
The front independent multi-link MacPherson strut suspension has the following advantages:

2899569

A double pivot design:
– Replaces conventional wishbone at each of the wheels with a pair of ball joints and lower control arms.
– Separates control of road inputs from handling responses.
– Delivers precise steering and smoother ride.
Direct-acting stabilizer bar aids cornering control.

Structural Adhesive and Weight Saving Aluminum Components
Greater use of structural adhesive and aluminum is helping to reduce the overall weight of the CTS sedans,
contributing to better ride and handling and reduced cabin noise. The CTS uses 387 feet of structural adhesive as a
bonding agent that holds together and stiffens load-bearing parts and components. The extensive use of adhesive
provides a damping effect, which reduces the transmission of vibration through the body structure. This results in
fewer squeaks and rattles reaching the driver. The heavy-duty material, along with traditional metal joining
processes like spot welding, also makes a stiffer and more durable joint. These advanced techniques, in addition to
the use of high-strength steels and efficient geometry helps make the CTS 40 percent stiffer than the previous
model.
To further improve performance, aluminum was used extensively to save weight. For the first time, all four doors are
constructed of aluminum, removing 55 lbs (25 kg) compared with the steel doors on the previous generation CTS.
With a base curb weight of 3,600 lbs (1633 kg), CTS is the lightest vehicle in its class.
Additional contributions to weight savings by using aluminum components are as follows:
• 13.1 lbs (5.9 kg) by replacing the steel bumpers with aluminum bumpers.
• 14.0 lbs (6.4 kg) by replacing the steel front strut towers with cast aluminum front strut towers.
• 7.2 lbs (3.2 kg) by replacing the cast magnesium instrument panel structure with an extruded and stamped
aluminum instrument panel structure.
• 36.5 lbs (16.6 kg) by replacing the steel powertrain cradle with an extruded and cast aluminum powertrain
cradle.
• Aluminum front and rear doors.
• Aluminum hood.

Run-Flat Tires
The CTS is factory equipped with run-flat tires. It does not have a spare tire, tire changing equipment, inflator kit or a
place to store a tire. The vehicle also has a Tire Pressure Monitor System (TPMS) that indicates a loss of tire
pressure in any of the tires. Run-flat tires can be driven on with no air pressure. There is no need to stop on the side
of the road to change the tire. Continue driving; however, do not drive too far or too fast. Driving on the tire may not
be possible if there is permanent damage. To prevent permanent damage, keep vehicle speed below 80 km/h (50
mph). With a light load the vehicle can be driven up to 60 mi (100 km); with a moderate load 50 mi (80 km); and a
heavy load 25 mi (45 km). As soon as possible, contact the nearest authorized GM or run-flat servicing facility for
inspection and repair or replacement. When driving on a deflated run-flat tire, avoid potholes and other road hazards
that could damage the tire and/or wheel beyond repair. When a tire has been damaged, or driven any distance while
deflated, check with an authorized run-flat tire service center to determine whether the tire can be repaired or should
be replaced. To maintain the run-flat feature, all replacement tires must be run-flat tires. The valve stems on run-flat
tires have sensors that are part of the TPMS. These sensors contain batteries that are designed to last for 10 years
under normal driving conditions. See your dealer for wheel or TPM sensor replacement.

To locate the nearest GM or run-flat servicing facility, call Customer Assistance. OnStar® can be used to make
this call.

GM Regular Production Option (RPO) Code Label Location

3618262

The GM regular production option (RPO) code label is located on the front of the rear compartment floor pan.

Transport Mode (Battery Saver Mode)
Transport mode (battery saver mode) reduces the parasitic load of some modules during overseas shipment or
during vehicle storage conditions. This improves the drain time on the battery for up to 70 days without the battery
going dead. When a vehicle is in transport mode, some features may have reduced functionality, such as disabling
