WHAT IS REVERSE BRAKING
ASSIST
The system is designed to reduce impact
damage or avoid a collision completely by
using the sensors on the rear of your vehicle.
The system functions when in reverse (R)
and traveling at a speed of 1–7 mph
(1.5–12 km/h).
If the system detects an obstacle behind your
vehicle, it provides a warning through the
rear parking aid or cross traffic alert system. REVERSE BRAKING ASSIST
PRECAUTIONS WARNING:
You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING:
Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system. This may
cause reduced performance or false alerts. WARNING:
Some situations and
objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types, and
pedestrians. Apply the brakes when
necessary. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
Do not use the system
with accessories that extend beyond the
front or rear of your vehicle, for example a
trailer hitch or bike rack. The system is not
able to make corrections for the additional
length of the accessories.
The system only applies the brakes for a
short period of time when an event occurs.
Act as soon as you notice the brakes apply
in order to remain in control of the vehicle.

Note:
Certain add-on devices around the
bumper or fascia may create false alerts. For
example, large trailer hitches, bicycle or
surfboard racks, license plate brackets,
bumper covers or any other device that may
block the normal detection zone of the
system. Remove the add-on device to
prevent false alerts.
Note: The system does not react to small or
moving objects, particularly those close to
the ground.
Note: The system does not operate during
hard acceleration or steering.
Note: If your vehicle sustains damage to the
bumper or fascia leaving it misaligned or
bent, it could alter the sensing zone causing
inaccurate measurement of obstacles or
false alerts. Note:
Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.
Note: When you connect a trailer, the system
may detect the trailer and provide an alert,
or the system turns off. If the system does
not turn off, switch the system off manually
after you connect the trailer.
Note: You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.

PRINCIPLE OF OPERATION
The traction control system helps avoid drive
wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces engine power at the
same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: The stability and traction
control light illuminates steadily if the
system detects a failure. Make sure you
did not manually disable the traction
control system using the information
display controls or the switch. If the stability
control and traction control light is still illuminating steadily, have the system
serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead to
an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
The system turns on each time you switch
on the ignition.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note: When you switch traction control off,
stability control remains fully active.
Switching the System Off
When you switch the system off or on, a
message appears in the information display
showing system status.
You can switch the system off by accessing
the traction control settings through the
touchscreen.
See Settings (page 540). Note:
If your vehicle detects a loss of traction
due to excessive wheel spin or deceleration,
a display message appears on the
touchscreen prompting you to disable
traction control if needed.
Using the Information Display Controls
You can switch this feature off or on in the
information display.
See General
Information (page 134).
System Indicator Lights and Messages The stability and traction control
light:
• Temporarily illuminates on engine
start-up.
• Flashes when a driving condition
activates either of the systems.
• Illuminates if a problem occurs in either
of the systems. The stability and traction control
off light temporarily illuminates on
engine start-up and stays on when
you switch the traction control system off.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death. WARNING:
Remember that even
advanced technology cannot defy the laws
of physics. It’ s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator’ s
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death. If your
electronic stability control system activates,
SLOW DOWN.
The system automatically turns on each time
you switch the ignition on.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions: •
The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the systems applies higher
brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by applying
brakes to one or more of the wheels
individually and, if necessary, reducing
engine power.
268
Aviator (CTV) Canada/United States of America, enUSA, Edition date: 202007, Second-Printing Stability Control

Roll Stability Control
The system enhances your vehicle
’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which it
changes by applying the brakes to one or
more wheels individually.
Curve Control
The system enhances your vehicle ’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
Control operates by reducing engine power
and, if necessary, applying brakes to one or
more of the wheels individually.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 267). Vehicle without stability control

B USING STABILITY CONTROL
The system automatically turns on each time
you switch the ignition on.
You cannot switch the stability control and
roll stability control systems off, but when
you shift into reverse (R), the systems
deactivate.
You can switch the traction control system
off or on.
