{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
. Adjust the climate control
system to circulate the air
inside the vehicle and set

the fan speed to the highest
setting. See“Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0206.
To save fuel, run the engine for
short periods to warm the vehicle
and then shut the engine off and
partially close the window. Moving
about to keep warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle and to
signal for help with the headlamps.
Do this as little as possible, to
save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow. If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See
Traction
Control/Electronic Stability Control
0 222.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a low
forward gear, spinning the wheels
as little as possible. To prevent
transmission wear, wait until the

222 Driving and Operating
Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction Control
System (TCS) and StabiliTrak/
Electronic Stability Control (ESC),
an electronic stability control
system. These systems help limit
wheel slip 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/ESC activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak/ESC selectively applies
braking pressure to any one of thevehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC begins to
limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come 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.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See
If the Vehicle Is Stuck 0190
and “Turning the Systems Off and
On” later in this section.
The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin
. Flash when StabiliTrak/ESC is
activated
. Turn on and stay on when either
system is not working
If either system fails to turn on or to
activate, a message displays in the
Driver Information Center (DIC), and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.

Ifdcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If

and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.

vehicle speed while descending a
very steep incline in a forward or
reverse gear.

Driver Mode Control Knob forAll-Wheel Drive (AWD)
q(Vehicles without AWD) or5(AWD equipped vehicles) Tour
Mode : Use Tour Mode during
normal driving conditions. Tour
Mode either puts the vehicle in
Front-Wheel Drive (AWD vehicles)
or is the normal drive mode (FWD
vehicles). Tour Mode is the most
fuel efficient drive mode. See
Driving for Better Fuel Economy
0 27. When selecting Tour Mode,
the AWD light will flash briefly while
the system disables, and then
stays off.
4AWD Mode : In AWD Mode, the
AWD system delivers power to all
four wheels and the system adjusts
as needed to improve traction.
Selecting AWD Mode will activate
the system. The AWD light will flash
briefly while the system is engaging
and stay on to indicate AWD is
active. AWD Mode will stay selected
until the mode is changed. AWD is
active in Tow/Haul and Off-Road
Modes. AWD Mode is only available
on vehicles equipped with AWD.
Tow/Haul and Off-Road Modes are
canceled with each ignition cycle
and will return to the Tour Mode.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and reduces AWD
performance to protect the system.
To restore full AWD operation and
prevent excessive wear on the
system, replace the compact spare
tire with a full-size tire as soon as
possible. See Compact Spare Tire
0 359.6Snow Mode : Snow Mode
improves vehicle acceleration on
snow and ice-covered roads. Snow
Mode is not available on vehicles
equipped with AWD.
7Off-Road Mode : Use Off-Road
Mode for public off-road recreational
driving. See Off-Road Driving 0183.
Off-Road Mode is only available on
vehicles equipped with AWD.
_Tow/Haul Mode : Tow/Haul
Mode can assist when towing or
hauling a heavy load. It changes
transmission shift patterns, turns on
AWD, if equipped, and increases
trailer sway control assistance.
When Tow/Haul is activated, the
Tow/Haul symbol will come on in the
instrument cluster. See Driving
Characteristics and Towing Tips
0 274. Tow/Haul Mode is only
available on vehicles with the towing
package.

230 Driving and Operating
Cruise Control
The cruise control lets the vehicle
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
With the Traction Control System
(TCS) or StabiliTrak/Electronic
Stability Control (ESC), the system
may begin to limit wheel spin while
you are using cruise control. If this
happens, the cruise control will automatically disengage. See
Traction Control/Electronic Stability
Control
0222. If a collision alert
occurs when cruise control is
activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System 0250. When
road conditions allow you to safely
use it again, cruise control can be
turned back on.
Cruise control will disengage if
either TCS or StabiliTrak/ESC is
turned off.
If Hill Descent Control (HDC) is
engaged, cruise control disengages.
See Hill Descent Control (HDC)
0 225.
If the brakes are applied, cruise
control disengages.
5: Press to turn the cruise control
system on and off. A white indicator
comes on in the instrument cluster
when cruise control is turned on.
*: Press to disengage cruise
control without erasing the set
speed from memory.
+RES : If there is a set speed in
memory, press briefly to resume that
speed or press and hold to
accelerate. If cruise control is
already active, use to increase
vehicle speed.
