GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 331). See
Warning Lamps and
Indicators (page 104).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move
the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake rapidly
by measuring the rate at which you press the
brake pedal. It provides maximum braking
efficiency as long as you press the pedal,
and can reduce stopping distances in critical
situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you switch the ignition on.
If the light does not illuminate
during start up, remains on or flashes, the
system may be disabled. Have the system
checked by an authorized dealer. If the
anti-lock brake system is disabled, normal
braking is still effective. If the brake warning lamp
illuminates when you release the
parking brake, have the system
checked by an authorized dealer. It also
illuminates momentarily when you switch the
ignition on to confirm the lamp is functional.
If it does not illuminate when you switch the
ignition on or begins to flash at any time,
have the system checked by an authorized
dealer.

AUTO HOLD
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake. WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
The system will turn off
if a malfunction is apparent. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death. Auto Hold uses your vehicle's brakes to hold
your vehicle at a stop once your vehicle has
reached a standstill condition. For example,
Auto Hold can assist you while stopping at
traffic lights or while in traffic jams by holding
the brake pressure for you once you bring
your vehicle to a stop.
Switch Auto Hold off during vehicle or trailer
towing.
Note:
In case of a malfunction in the system
while Auto Hold actively holds the vehicle
(for example, low power supply), a message
appears in the information display asking
you to press the brake pedal. If you see this
message, press the brake pedal
immediately.
Note: Auto Hold only activates if the system
recognizes it is applying enough brake
pressure. On a steep hill or incline, you may
need to make sure the brake pedal is
pressed sufficiently to activate the Auto Hold
system. Note:
In some cases, Auto Hold might hand
over to the parking brake. When the parking
brake applies, the red brake lamp appears.
This is normal. When you press the
accelerator pedal, the drive away release
feature releases the parking brake.
Note: Auto Hold works on all road grades.

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 automatically turns on each time
you switch the ignition on.
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 either using
the information display controls or the switch. Using the Information Display Controls
You can switch this feature off or on in the
information display. See General Information
(page
109).
Using a Switch
(If Equipped)
Use the traction control switch on the
instrument panel to switch the system off or
on.
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: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. 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:
The system may not
detect small or moving objects, particularly
those close to the ground.
Note: If your vehicle has MyKey™, the sensing
system cannot be switched off when a
MyKey™ is present.
See Principle of
Operation (page 62). Note:
Keep the sensors on the bumper or
fascia free from snow, ice and large
accumulations of dirt. If the sensors are
covered, the system’ s accuracy can be
affected. Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to the
bumper or fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike 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: When you connect a trailer to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when you connect a
trailer to prevent the alert. The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
You can switch the system off through the
information display menu or from the pop-up
message that appears once you shift the
transmission into reverse (R).
See General
Information (page 109). If your vehicle has a
parking aid button, you can switch the
system off by pressing the button.
If a fault is present in the system, a warning
message appears in the information display.
See
Information Messages (page 115).
REAR PARKING AID WARNING:

•
As the distance to the object decreases,
the indicator blocks illuminate and move
toward the vehicle icon.
• If there is no object detected, the
distance indicator blocks are gray.
When you shift into reverse (R), the system
provides audible warnings and visual
indication when detected objects are within
24 in (60 cm) and are inside the driving path
of your vehicle. When you stop your vehicle,
the audible warnings turn off after two
seconds.
When you shift into any forward gear, the
system provides audible warnings and visual
indication when your vehicle is moving at a
speed of approximately
5 mph (8 km/h) or
below and the system detects an object
within the detection zone. When you stop
your vehicle, the audible warnings turn off
after two seconds and visual indication turns
off after four seconds. When you shift into neutral (N), the system
only provides visual indication if your vehicle
is moving at a speed of approximately 5 mph
(8 km/h)
or below. For example, your vehicle
is moving on a slope, and the system detects
an object moving toward your vehicle. When
you stop your vehicle, visual indication turns
off after four seconds.
If the system is not available, the side
distance indicator blocks do not display.
ACTIVE PARK ASSIST
(IF EQUIPPED) WARNING: You must remain in your
