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 104).
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

USING TERRAIN CONTROL
The terrain management system optimizes
drivability and comfort as well as
maximizing traction while operating on
different types of terrain.
Turn the control located on the center
console to choose between the following
modes:
Grass/Gravel/Snow mode
should be selected where a firm
surface is covered with loose or
slippery material such as packed
snow, ice, water, grass, or a thin
layer of gravel or sand. For deep
1
gravel or sand, select Sand
mode. If the vehicle cannot gain
traction in deep snow, switching
off the traction control system
may help (switch traction
control back on when you regain
traction). See
Using Traction
Control (page 196).
Sand
mode should be selected
in soft dry sand or deep gravel. If
crossing wet sand that may be
sufficiently deep enough for the
wheels to sink into the surface,
select Mud/Ruts mode.
2 Mud/Ruts
mode should be
selected for muddy, rutted, soft
or uneven terrain.
3
Normal
mode is for on-road
conditions and should be
selected before driving on
surfaces which are similar to a
hard road surface or once the
need for a special mode has
passed. Select Normal mode
when towing a trailer.
4
Note: The Sand and Mud/Ruts modes are
for off-road use only.
Note: The curve control portion of the
AdvanceTrac® system is unavailable when
you select Sand or Mud/Ruts.
If the system becomes inoperable,
selecting some modes may not be possible
and a message displays. If it becomes
inoperable due to a system malfunction,
all of the mode indicators on the control
turn off and one of the following messages
appears in the information display:

USING HILL DESCENT
CONTROL
Principle of operation
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as
ice or extremely steep grades. Hill
descent control is a driver assist system
and cannot substitute for good judgment
by the driver. Failure to do so may result
in loss of vehicle control, crash or serious
injury. WARNING:
Hill descent control
does not provide hill hold at zero miles
per hour (0 kilometers per hour). When
stopped, the parking brake must be
applied or the vehicle must be placed in
P
(Park) or it may roll away.
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep grades in various surface
conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between 3 mph
(5 km/h)
and 20 mph (32 km/h). Above
20 mph (32 km/h), the system remains
armed, but descent speed cannot be set
or maintained.
Hill descent control requires a cooling
down interval after a period of sustained
use. The amount of time that the feature
can remain active before cooling varies
with conditions. The system provides a
warning in the message center and a chime
sounds when the system is about to
disengage for cooling. At this time,
manually apply the brakes as needed to
maintain descent speed. Using hill descent control Press and release the hill
descent button located in the
center of the terrain
management control. A light in the control
illuminates and a chime sounds when this
feature activates.
To increase descent speed, press the
accelerator pedal until you reach the
desired speed. To decrease descent speed,
press the brake pedal until you reach the
desired speed.
Whether accelerating or decelerating, once
you reach the desired descent speed,
remove your feet from the pedals and hill
descent control maintains the chosen
vehicle speed.
Note: You may observe noise from the ABS
pump motor during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.

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 is equipped with
MyKey ™, the sensing system cannot be
turned off when a MyKey ™ is present.
See
Principle of Operation (page 60).
Note: Keep the sensors, located 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 a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when a trailer is
connected 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.
The system can be switched off through
the information display menu or from the
pop-up message that appears once you
shift the transmission into reverse (R). See

If the transmission is in reverse (R), the
front sensing system provides audio
warnings when your vehicle is moving and
the detected obstacle is moving towards
your vehicle. Once the vehicle is stationary,
the audio warning will be stopped after 2
seconds. Visual indication is always
present in reverse (R).
If the transmission is in drive (D) or any
other forward gear (for example, low (L),
sport (S) or any forward gear in a manual
transmission), the front sensing system
provides audio and visual warnings when
your vehicle is moving below a speed of
5 mph (8 km/h) and an obstacle is located
inside the detection area. Once the vehicle
is stationary, the audio warning will be
stopped after 2 seconds and the visual
indication stops after 4 seconds. If the
obstacles detected are within
12 in
(30 cm), the visual indication remains on. If the transmission is in neutral (N), the
system provides visual indication only
when your vehicle is moving at
5 mph
(8 km/h) or below and an obstacle is
located inside the detection area. Once
your vehicle is stationary, the visual
indication will stop after 4 seconds.
SIDE SENSING SYSTEM
(IF
EQUIPPED)
The side sensing system uses the front and
rear side sensors to detect and map
obstacles within the vehicle's driving path,
located near the sides of your vehicle. The
side sensors are active when the
transmission is in any position other than
park (P).
Note: Obstacles that enter the side
detection area without being detected and
mapped by the front or rear side sensors will
not be detected. Coverage area is up to 24 in (60 cm) from
the sides of your vehicle.
When the system detects an object close
