experience because the rear suspension better follows
the lead of the front suspension. The Z-link design is
also lighter and requires less space than a typical fully
independent rear suspension. The lower weight
enhances efficiency, while the compact design enables
the Cascada’s generous cargo room.
Electric Power Steering
Steering inputs are executed by a fuel-saving,
rack-mounted electric power steering system. It does
not have power steering fluid. Regular maintenance is
not required. If power steering assist is lost due to a
system malfunction, the vehicle can be steered, but it
may require increased effort. If the steering wheel is
turned until it reaches the end of its travel and is held
against that position for an extended period of time,
power steering assist may be reduced. Normal use of
the power steering assist should return when the
system cools down.

Traction Control and StabiliTrak®
The vehicle has a Traction Control System (TCS) and
Stabilitrak® which is an electronic stability control
system. These systems help limit wheel spin and assist
the driver in maintaining control, especially on slippery
road conditions.
TCS activates if it senses that any of the drive wheels
are spinning or beginning to lose traction. When this
happens, TCS applies the brakes to the spinning
wheels and reduces engine power to limit wheel spin.
Stabilitrak® activates when the vehicle senses a
difference between the intended path and the direction
the vehicle is actually traveling. The system selectively
applies braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping the vehicle
on the intended path.
If cruise control is being used and TCS or StabiliTrak®
begins to limit wheel spin, the cruise control will
disengage. Cruise control may be turned back ON
when road conditions allow. Both systems turn ON
automatically when the vehicle is started and begins to
move. The systems may be heard or felt while they are
operating or while performing diagnostic checks. This is
normal and does not mean there is a problem with the
vehicle.
⇒ If the vehicle gets stuck in sand, mud, ice, or snow
it may be necessary to turn TCS OFF.

The Rollover Protection System is controlled by the
Inflatable Restraint Sensing and Diagnostic Module
(SDM). The system activates during a vehicle rollover,
head-on collision or side impact. The system deploys
with the soft top opened or closed.

including the reinforced A-pillars, V-braces, the rollover
bars in an extended state and the reinforced torsion
box bulkhead.
The rollover protection system consists of a reinforced
windscreen frame and rollover bars under covers
behind the rear head restraints. In the event of a vehicle
rollover, head-on collision or side impact, the
pyrotechnically activated, spring-loaded bars deploy
upwards automatically within milliseconds. They also
deploy together with the front and side airbag systems.

the first detent to raise it. The switches work when the
ignition is in ON/RUN or ACC/ ACCESSORY, or in
Retained Accessory Power (RAP).
Express Window Operation
Windows with an express-down or up feature allow the
windows to be lowered or raised without holding the
switch. All door windows have the express-down
feature. Front door windows may also have the
express-up feature. Pull a window switch up or push it
down all the way, release it, and the window goes up or
down automatically. Stop the window by pushing or
pulling the switch.

4355458

Express Window Anti-Pinch Feature
If any object is in the path of the window when the
express-up is active, the window will stop at the
obstruction and auto-reverse to a preset factory
position. Weather conditions such as severe icing may
also cause the window to auto-reverse. The window will
return to normal operation after the obstruction or
condition is removed.

DO NOT place any objects on the covers of the rollover
bars behind the head restraints.
The airbag control indicator illuminates if the rollover
bars have been deployed. The soft top MUST NOT be
operated if the rollover bars have been deployed. A
continuous warning will sound and a message appears
in the DIC if the switch is actuated.

Express Window Anti-Pinch Override
To override the anti-pinch feature, hold the window
switch all the way up to the second position. The
window will raise for as long as the switch is held. Once
the switch is released, the express mode is reactivated.
In this mode, the window can close on an object in its
path. Use care when using the override mode.

Airbag System
All vehicle airbags have the word AIRBAG on the trim
or on a label near the deployment opening. The airbags
are located in the following positions:
– Driver steering wheel (dual inflators).
– Passenger side instrument panel (dual inflators).
– Knee airbag for the driver.
– Knee airbag for the front outboard passenger.
– Seat-mounted side impact airbag for the driver.
– Seat-mounted side impact airbag for the front

shifted into R (reverse), the RVC shows what is
behind the vehicle on the radio display and
provides onscreen track paths to help guide the
driver. Displayed images may be farther or closer

provides a visual alert and rapidly beeps when
approaching a vehicle directly ahead too quickly.
When this Forward Collision Alert occurs, the
brake system may prepare for driver braking to
occur more rapidly which can cause a brief, mild
deceleration. The Cascada does not illuminate an
amber indicator when following too closely. The
forward-looking FCA camera sensor is on the
windshield ahead of the rearview mirror. FCA
detects vehicles within a distance of
approximately 197 ft (60 m) and operates at
speeds above 25 mph (40 km/h).

Lane Departure Warning (LDW): If equipped,
LDW may help avoid crashes due to unintentional
lane departures. It may provide an alert if the
vehicle is crossing a lane without using a turn
signal in that direction. LDW uses a camera
sensor to detect the lane markings at speeds of
35 mph (56 km/h) or greater. When LDW is ON,
the indicator is green if LDW is available to warn of
a lane departure. If the vehicle crosses a detected
lane marking without using the turn signal in that
direction, the indicator changes to amber and
flashes.
Rear Park Assist (RPA): With RPA, as the
vehicle backs up at speeds of less than 5 mph
(8 km/h), the sensors on the rear bumper detect
objects up to 8 ft (2.5 m) behind the vehicle that
are within a zone 10 in (25 cm) high off the ground
and below bumper level.
Front Park Assist: If equipped with Front Parking
Assist (FPA), it also detects objects 4 ft (1.2 m) in
front of the vehicle.

Towing the Vehicle — Recreational
Vehicle Towing
Towing the Vehicle
Have the vehicle towed on a flatbed car carrier. A wheel
lift tow truck could damage the vehicle.
Recreational Vehicle Towing
Recreational vehicle towing means towing the vehicle
behind another vehicle, such as behind a motor home.
The Cascada was not designed to be towed with all
four wheels on the ground, so If the vehicle will be
towed a dolly must be used under the front wheels.

Dolly Towing
Dolly towing is towing the vehicle with two wheels on
the ground and two wheels up on a device known as a
dolly. Tow the vehicle with the two rear wheels on the
ground and the front wheels on a dolly.
To tow the vehicle with two wheels on the ground and a
dolly perform the following:
1. Put the front wheels on a dolly.
2. Put the shift lever in P (Park).
3. Secure the vehicle to the dolly.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
