Cadillac dealer or an ELR Concierge representative for more information.

Transmission
The 4ET50 — RPO MKA, is a fully automatic front wheel drive transaxle, variable-speed, electronically controlled transmission. It consists primarily of a torque
dampener assembly, an integral main and auxiliary fluid pump and housing, 1 planetary gear set, 2 friction (rotating) and 1 mechanical (stationary) clutch
assemblies, a hydraulic pressurization and control system, and two internal electric motors. Drive motor generator A is 55 kW and drive motor generator B is
135 kW.
The torque dampener contains internal torsional springs, fluid, input shaft and a clutch. The torque dampener acts as a spring coupling to smoothly transmit
power from the engine flexplate to the transmission. The dampener provides a mechanical direct drive coupling of the engine to the transmission. The clutch is
applied during engine starting and stopping events.
The planetary gear set provides the Electrically Variable forward mode ratios and reverse. Changing ratios is fully automatic and is accomplished through the
use of a transmission control module (TCM) located inside the transmission and the drive motor generator power inverter module located under hood. Both the
TCM and the drive motor generator power inverter module receives and monitors various electronic sensor inputs and uses this information to vary the torque
output at the optimum time based on throttle position.
The TCM commands shift solenoids and variable bleed pressure control solenoids to control torque timing and feel. All the solenoids, including the TCM, are
packaged into a self-contained control solenoid valve assembly.
The main hydraulic system primarily consists of a gerotor-type pump, control valve body assemblies, dampener housing and case. The pump maintains the
working pressures needed to stroke the clutch pistons that apply or release the friction components. These friction components, when applied or released,
support the automatic ratios qualities of the transmission.
The hydraulic system also uses a secondary system and consists of an auxiliary pump located inside of the transmission. This is a gerotor-type pump, electric
three phase High Voltage motor, electric harness, and control module. The control module is located inside of the drive motor generator power inverter module
under the hood. This pump maintains working pressures when the engine is off.
The friction components used in this transmission consist of 3 multiple disc clutches. The multiple disc clutches combine with a planetary gear set and electric
motor to deliver the different ratios, forward and reverse. The gear set then transfers torque through the final drive assembly.
The transmission may be operated in any of the following gear ranges:
–

P (PARK) This position locks the wheels and prevents the vehicle from rolling either forward or backward.

–

R (REVERSE) This position allows the vehicle to be operated in a rearward direction. This is done by the Drive Motor with Generator B and is electric.

–

N (Neutral) In this position, the propulsion system does not connect with the wheels.

–

D (Drive) Drive range should be used for all normal driving conditions for maximum efficiency and fuel economy. Drive range allows the transmission to
operate in electrically variable modes providing various ratios and output torque.

–

L (Low) This position is used for the feel of engine braking by maximizing regenerative braking once the throttle is lifted. While in this position the vehicle
will slow quicker and use the drive motor generator B to more aggressively collect energy during a regenerative braking event.

Drive Modes and PRNDL Selection

There are four operating Drive Modes. The vehicle will always default to Tour Mode on every key cycle. Press the Drive Mode button on the center console to
scroll through a menu of operating modes. After three seconds, the highlighted mode will become active in the Instrument Cluster.
–

Tour Mode: Use Tour Mode when possible in normal driving conditions for efficient operation.

–

Sport Mode: Use Sport Mode when more responsive acceleration is desired from a stop. Sport Mode provides more responsive acceleration than Tour
Mode, but can reduce efficiency.

–

Mountain Mode: Use Mountain Mode prior to climbing long, steep grades in mountainous areas. Be sure to engage Mountain Mode before starting to
climb. Mountain Mode reduces electric range and power, but may be needed to maintain speeds above 60 mph (97 km/h) when climbing grades of 5%
or greater.

–

Hold Mode: Use Hold Mode on a trip where all or most of the electric charge will be depleted. Use Hold Mode mainly during highway or high-speed
driving to maximize both electric vehicle miles and fuel efficiency.

–

L (Low) Use L (Low) in heavy stop-and-go traffic or when traveling downhill. L requires less brake pedal application and provides a controlled, efficient
way to slow the vehicle down, by maximizing regenerative braking.

Climate Control
Climate Control Touch Screen

16

The fan, air delivery mode, driver and passenger temperatures, A/C mode, and SYNC settings can be controlled by pressing the CLIMATE icon on the
infotainment home screen (shown) or the climate button in the touch screen application tray. A selection can then be made on the front climate control page that
is displayed.

Climate Control Touch Screen Controls — Climate Modes

Optimal efficiency is achieved with the heat, air conditioning and fan turned OFF.
Touch the climate mode settings to adjust the impact the climate control system has on the vehicle’s efficiency. The most efficient Mode operation is in the
following order:
–

MIN Electric cabin heating/cooling is OFF.

–

ECO Limits cabin heating/cooling to balance comfort with energy use.

–

MAX Provides the most cabin heating/cooling but uses the most energy.

Use the heated seats and heated steering wheel to reduce the demand on the cabin heating system. Heating the seats and steering wheel uses less energy
than heating the vehicle interior.

Heating and Air Conditioning
Heating System
The heating system uses the engine and a high voltage heater to provide heat to the passenger compartment. The high voltage heater is used when the engine
is not running and passenger compartment heat is requested. The high voltage heater provides different levels of heat depending on the amount of heat needed
and outside temperature. The HVAC Control Module turns on the coolant pump and monitors the temperature sensors in the passenger compartment, outside
air, engine radiator, high voltage heater and the engine to determine the position of the coolant flow control valve and if the high voltage heater is needed.
Passenger compartment heat is provided by air flowing through the heater core. The heater core is heated by coolant from either the engine or the high voltage
heater. The engine cooling system circulates a 50/50 mixture of Dex-cool and deionized water.

Air Conditioning
The 300 V high voltage electric A/C compressor is a self contained high voltage inverter, electric motor, and direct coupled compressor. The electric A/C
compressor has the ability to run and provide cooling performance even when the vehicle engine is not running. This feature enables the electric A/C

17

compressor to run at a speed independent of the engine. The electronic climate control module and the Vehicle Integration Control Module (VICM) will command
the electric A/C compressor to a speed necessary to maintain a desired cooling level rather than cycle the electric A/C compressor ON and OFF.
The A/C system uses R-134a refrigerant which is a gas at very low temperatures and can transfer heat from the passenger compartment and high voltage
battery to the outside air. The A/C system also uses POE (Polyol Ester) refrigerant oil instead of PAG (Polyalkylene Glycol) because it is less hygroscopic. The
A/C compressor features a high RPM scroll compressor that is pulse width modulated. During conditions with high ambient temperatures and high humidity, the
driver may notice a unique high-pitched sound from the compressor. This is considered a normal characteristic, and it may be heard when the vehicle is
stopped or at low speeds. The A/C compressor is serviced as a unit.

Driver Assistance Systems
The driver assistance features are based on a "control and alert" strategy that helps identify potential collision situations and intervenes when a collision threat
appears more imminent, employing visual, audible and/or tactile (vibration) alerts.
The following four Driver Assistance Systems are standard equipment on the ELR:
–

Lane Departure Warning When crossing a detected lane marking without using a turn signal, a visual alert flashes on the instrument cluster and the
left or right side of the driver’s seat pulses. See Safety Alert Seat. Press the Lane Departure Warning button on the left side of the CUE touch screen to
turn the system ON or OFF. The button illuminates when the system is ON.

–

Forward Collision Alert When approaching a vehicle directly ahead too quickly, a visual alert flashes on the windshield and the driver’s seat pulses.
See Safety Alert Seat. Press the Collision Alert button or the Follow Distance Gap button if equipped with Adaptive Cruise Control on the left side of the
steering wheel to set the alert timing.

–

Safety Alert Seat Subtle seat cushion vibration pulses, left or right, or simultaneously, to alert the driver of potential hazards. Audible notification may be
selected instead of Safety Alert Seat vibration notification; to change the setting, go to Collision/Detection Systems in the Vehicle Settings menu.

–

Rear Vision Camera When the vehicle is in R (Reverse), a view of the area behind the vehicle appears on the CUE touch screen.

In addition to the standard equipment, the following Driver Assistance Systems are included in the Luxury Package:
–

IntelliBeam® Automatically turns the high-beam headlamps ON or OFF depending on traffic conditions.

–

Side Blind Zone Alert When a vehicle is detected in a side blind spot area, a warning symbol displays on the side mirror. To turn OFF the system, go
to Collision/Detection Systems in the Vehicle Settings menu.

18

–

Rear Cross Traffic Alert Warns of traffic coming in either direction by displaying a visual alert on the Rear Vision Camera screen, and the left or right
side of the driver’s seat pulses. See Safety Alert Seat. To turn the system ON or OFF, go to Collision/Detection Systems in the Vehicle Settings menu.

–

Adaptive Cruise Control If a vehicle is detected ahead, the vehicle accelerates or brakes moderately to maintain the selected following gap. If driver
action is required, a visual alert flashes on the windshield and the driver’s seat pulses. See Safety Alert Seat. Press the Follow Distance Gap button on
the left side of the steering wheel to set a following gap.

–

Automatic Collision Preparation Included with Adaptive Cruise Control, this feature prepares the brakes or applies the brakes if an emergency
collision appears immediate or the driver does not react to previous alerts.

Aerodynamic Enhancements
The ELR offers improved aerodynamics for better range and efficiency. This includes a lower front air dam, low flow front grill, lower grill shutters, rear spoiler
and low rolling resistance tires. It is normal for the flexible air dam to occasionally contact the road surface on steep driveways or parking structures. It is also
important that the vehicle is not pulled against tall curbs to prevent fascia and air dam contact.
Customers may also comment on wind buffeting when driving at higher speeds with a window down. This is a result of the aerodynamic shape of the vehicle to
increase range and efficiency.

Airbags
Airbags are designed to supplement the protection provided by safety belts.
Notice: The vehicle is equipped with the following airbags:

•

A frontal airbag for the driver.

•

A frontal airbag for the front outboard passenger.

•

A knee airbag for the driver.

•

A knee airbag for the front outboard passenger.

•

A seat-mounted side impact airbag for the driver.

•

A seat-mounted side impact airbag for the front outboard passenger.

•

Seat-mounted side impact airbags for the second row outboard passengers.

•

A roof-rail airbag for the driver and the passenger seated directly behind the driver.

•

A roof-rail airbag for the front outboard passenger and the passenger seated directly behind the front outboard passenger.

Tire Inflator Module
The ELR features a tire inflation kit instead of a spare tire. In the event of a flat tire, the tire sealer should be used in combination with the air compressor to
inflate the tire. The tire inflation kit is located in the rear hatch under the storage compartment, where the spare tire is normally located. It is important to note that
there is no spare tire, and the tires are not run-flat tires. Any tire or wheel damage that is not repairable with the tire sealer and air compressor requires that the
vehicle be flat-bed carried to the nearest tire repair facility.

12 V Absorbed Gas Mat (AGM) Battery

19

Notice: The 12 V battery used in the ELR is an Absorbed Gas Mat (AGM) type battery that requires different charging voltages than conventional
lead acid batteries. The essential tool (GR-8) EL-50313 has this algorithm built in. You must select AGM when prompted or damage to the battery
will result.
The Cadillac ELR uses the 12 V battery to "wake up" and initialize control modules. If the vehicle does not power up, verify that the 12 V battery is sufficiently
charged to allow for all of the control modules to wake up and initialize. The vehicle does not use a traditional 12 V starter motor to crank the ICE. A much more
powerful 300 V motor, drive motor 1, located within the transmission is utilized to crank the ICE. Drive motor 1 can rotate the ICE to an operating speed of 800
RPM within just a few hundred milliseconds.
To prevent excessive drain on the 12 V system and a potential no start condition, it is recommended that customers allow the vehicle to remain in Run when
listening to the radio for extended periods of time. It is important that when exiting the vehicle, ensure the system is powered OFF by verifying the instrument
cluster is no longer active and there is no power steering.

Jump Starting the ELR 12V Battery

1. Positive (+) Terminal
2. Negative (−) Terminal
If the ELR will not start, the 12-volt battery may be run down. Use the key to open the trunk. To jump start the ELR, jumper cables are connected directly to the
positive (+) and negative (−) terminals on the 12-volt battery in the rear cargo area. The other vehicle used to jump start the ELR must have a 12-volt battery
with a negative ground system. Park both vehicles close enough so that the jumper cables can reach both vehicles' positive (+) and negative (−) terminals.
When jump starting, the vehicles must not touch each other. It could cause an unwanted ground connection that could damage both vehicles' electrical
systems.

Low Profile Lift Arms System — Hoist Contact Lift Points
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 the lifting
equipment being used. Refer to the hoist manufacture's recommendation for their applications of low profile lift arms system for their lifting equipment.

20

This is a view of the proper front hoist contact lift point.

This is a view of the proper rear hoist contact lift point.

Before setting or raising the vehicle, in order to determine the proper front and rear hoist contact lift points, refer to the preceding graphics.

Towing A Disabled Vehicle
Notice: Please advise the customer to share this information with their towing provider.

Towing the Vehicle / Flatbed Car Carrier
Notice: Incorrectly towing a disabled vehicle may cause damage. A wheel lift tow truck could damage the vehicle. The damage would not be
covered by the vehicle warranty.
Have the vehicle towed on a flatbed car carrier. Ramps are required for the front fascia to clear the flatbed. North American vehicles do not have a tow eye.
The ramp height should be approximately 4 in (102 mm). Lower the flatbed onto the set of ramps.
To load a vehicle onto a flatbed carrier perform the following:
1.

The vehicle MUST be on a flat surface.
⇒

2.

If the vehicle is parked off the shoulder of the road, at an angle that it cannot be pulled onto a flatbed, a hook/chain can be placed into either of the
front torque box openings to pull the vehicle onto a flat surface. Make sure that the tow chains do not come in contact with the rocker panel or the
front fascia.

The front tires must be properly inflated. If necessary, move a rear tire to the front to replace a flat or damaged tire.

21

3.

Place the tow chain hooks (2) into one of the torque box openings (1) behind the front wheels.

4.

Place a 4 ft (1.2 m) X 4 in (102 mm) wood beam (4) under the front cradle crossmember (3), and on top of both tow chains (5) to ensure the tow chains
do not come into contact with the front fascia (1). Try to minimize the contact of the chains with the flexible air dam (2).

5.

Ramps (2) are required for the front fascia (3) to clear the flatbed (1). The ramp height should be approximately 4 in (102 mm). Lower the flatbed onto
the set of ramps.

6.

After the front tires are on the flatbed adjust the flatbed upward to provide additional clearance between the air dam, fascia, and flatbed.

7.

When the fascia has enough clearance to clear the flatbed, lower the flatbed, and finish pulling the vehicle onto the flatbed.

8.

Use the proper nylon strap harnesses around the tires to secure them to the flatbed car carrier.
