the fan speed to the highest
setting. See“Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0188.
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 0199.
{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
wheels stop spinning before shifting gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see
Towing the Vehicle 0295.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry: the Tire and
Loading Information label and
the Certification label.

for passing, push the pedal down to
achieve the desired level of
acceleration.
Downshifting the transmission in
slippery road conditions could result
in skidding. See“Skidding”under
Loss of Control 0164.
The transmission can be shifted like
a manual transmission using the
paddle shift controls while in
D (Drive). See Manual Mode0191.
M : In M (Manual Mode), the
transmission can be shifted like a
manual transmission using the
paddle shift controls. See Manual
Mode 0191.Manual Mode
Manual Paddle Shift
When the shift lever is moved to
M (Manual Mode), the transmission
enters Manual Mode. The
transmission will hold the current
gear until a change is requested.
The paddles on the steering wheel
can be used to manually upshift or
downshift the transmission. The
right (+) plus paddle upshifts, and
the left (−) minus paddle downshifts.
When using the Manual Paddle
Shift feature while in M (Manual
Mode), the current gear will be
displayed in the instrument cluster,
or the Head-Up Display (HUD),
if equipped. See Head-Up Display
(HUD) 0117.
When accelerating the vehicle from
a stop in snowy and icy conditions,
shifting to 2 (Second) gear allows
the vehicle to gain more traction.
The Manual Paddle Shift system
can be deactivated by moving the
shift lever from M (Manual Mode)
back to D (Drive).

accelerator pedals in preparation for
starting the vehicle moving in the
intended direction. In this case,
there is no need to push the switch
to release the EPB.
Brake Assist
The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal as
the driving situation dictates. The
Brake Assist feature will
automatically disengage when thebrake pedal is released or brake
pedal pressure is quickly
decreased.
Hill Start Assist (HSA)
If equipped, Hill Start Assist (HSA)
may automatically activate when the
vehicle is stopped on a grade. This
feature is designed to prevent the
vehicle from rolling, either forward or
rearward, during vehicle drive off.
During the transition from releasing
the brake pedal to accelerating to
drive off on a grade, HSA holds the
braking pressure to prevent rolling.
HSA will not activate if the vehicle is
in a drive gear and facing downhill
or if the vehicle is facing uphill and
in R (Reverse).
Ride Control Systems
Traction Control/
Electronic Stability
Control
The vehicle has a Traction Control
System (TCS) and a StabiliTrak
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 the
rear wheels are spinning too much
or are beginning to lose traction.
When this happens, TCS applies
the brakes to the spinning wheel
and reduces engine power (by
closing the throttle and managing
engine spark) to limit wheel spin.
StabiliTrak activates when the
vehicle senses a difference between
the intended path and the direction
the vehicle is actually traveling.
StabiliTrak selectively applies
braking pressure to any one of the
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.

. Available in Track Mode.
. There are five selectable
settings if Competitive Driving
Mode is activated.
Competitive Driving Mode
If equipped, Competitive Driving
Mode, Performance Traction
Management, and Launch Control
are systems designed to allow
increased performance while
accelerating and/or cornering. This
is accomplished by regulating and
optimizing the engine, brakes, and
suspension performance. These
modes are for use at a closed
course race track and are not
intended for use on public roads.
They will not compensate for driver
inexperience or lack of familiarity
with the race track. Drivers who
prefer to allow the system to have
more control of the engine, brake, and suspension are advised to turn
the normal traction control and
StabiliTrak systems on.
Caution
Attempting to shift when the drive
wheels are spinning and do not
have traction may cause damage
to the transmission. Damage
caused by misuse of the vehicle
is not covered by the vehicle
warranty. Do not attempt to shift
when the drive wheels do not
have traction.
Competitive Driving Mode
Competitive Driving Mode allows full
engine power while StabiliTrak
helps maintain directional control of
the vehicle by selective brake
application. In this mode, TCS is off.
Launch Control is available if in
Track Mode. Adjust your driving
style to account for the available
engine power. See
“Launch Control”
later in this section.
These lights are on when the
vehicle is in the Competitive
Driving Mode.

Performance Traction Management
(PTM) integrates the Traction
Control, StabiliTrak, and Magnetic
Ride Control systems to provide
improved and consistent
performance when cornering. The amount of available engine power is
based on the mode selected, track
conditions, driver skill, and the
radius of each corner.
This light is on when the vehicle is
in the PTM mode.
To select this optional handling
mode, the vehicle mode must be
Track. Then quickly press the TCS/

To experience the performance
benefit of this system, after entering
a curve and at the point where
normal acceleration occurs, fully
push the accelerator pedal. The
PTM system will modify the level of
engine power for a smooth and
consistent corner exit.
The PTM system contains five
modes. These modes are selected
by turning the Selective Ride
