3. Turn the ignition to LOCK/OFF.
4. Remove the key.
Leaving the Vehicle With the
Engine Running
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
The vehicle could move suddenly
if the shift lever is not fully in
P (Park) with the parking brake
firmly set. And, if you leave the
vehicle with the engine running,
it could overheat and even catch
fire. You or others could be injured.
Do not leave the vehicle with the
engine running.
If you have to leave the vehicle
with the engine running, the vehicle
must be in P (Park) and the parking
brake set.
Release the button and check that
the shift lever cannot be moved
out of P (Park).
Torque Lock
Torque lock is when the weight of
the vehicle puts too much force on
the parking pawl in the transmission.
This happens when parking on a hill
and shifting the transmission into
P (Park) is not done properly and
then it is difficult to shift out of
P (Park). To prevent torque lock,
set the parking brake and then
shift into P (Park). To find out how,
see “Shifting Into P (Park)” listed
previously.
If torque lock does occur, the
vehicle may need to be pushed
uphill by another vehicle to relieve
the parking pawl pressure, so
you can shift out of P (Park).
Shifting Out of Park
This vehicle is equipped with an
electronic shift lock release system.
The shift lock release is designed to:
•Prevent ignition key removal
unless the shift lever is in P (Park)
with the shift lever button fully
released.
•Prevent movement of the shift
lever out of P (Park), unless the
ignition is in ON/RUN or ACC/
ACCESSORY and the brake
pedal is applied.
The shift lock release is always
functional except in the case of
an uncharged or low voltage
(less than 9 volt) battery.
8-22 Driving and Operating
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
The system utilizes engine and
braking controls to control wheel
spin during acceleration at all driving
speeds for maximum driver control
regardless of conditions. When the
system senses impending wheel slip
during acceleration, it signals the
throttle control to reduce drive wheel
torque. Under extreme situations,
such as going from pavement to ice
during acceleration, the system
will selectively apply the brakes to
maintain control. The system may
be heard or felt while it is working,
but this is normal.The TCS/StabiliTrak warning light
flashes when the traction control
system is limiting wheel spin.
The StabiliTrak/TCS warning light
comes on solid if there is a problem
with the traction control system.
SeeTraction Control System
(TCS)/StabiliTrak
®Light on
page 4-24for more information.
If the light stays on, see your
dealer/retailer for service. When the
TCS/StabiliTrak warning light is on,
the system will not limit wheel spin.
Adjust your driving accordingly.
TCS automatically comes on
whenever the vehicle is started.
To limit wheel spin, especially in
slippery road conditions, the systemshould always be left on, but it may
be necessary to turn the system off if
the vehicle is stuck in sand, mud or
snow and rocking the vehicle is
required. Also, turn TCS off while
in deep snow or on loose gravel,
to assist vehicle motion at lower
speeds. SeeIf the Vehicle is Stuck
on page 8-11for more information.
See alsoWinter Driving on
page 8-10for information on using
TCS when driving in snowy or icy
conditions.
To turn the system off, press
and release the StabiliTrak/TCS
button located on the console
in front of the shift lever.
8-34 Driving and Operating
StabiliTrak comes on automatically
whenever the vehicle is started.
The system should be left on to
help assist with directional control
of the vehicle. If StabiliTrak needs
to be turned off, press and hold the
StabiliTrak/TCS button until theTraction Control Off light and the
StabiliTrak Off light come on the
instrument panel cluster. If the
system has been turned off, press
and release the StabiliTrak/TCS
button to turn the system back on.
Engine Drag Control (EDC)
EDC improves vehicle stability by
sensing if there is difference in speed
between the free rolling front wheels
and the rear drive wheels that often
occurs when the driver takes their
foot off the accelerator pedal on
slippery surfaces (snow, ice, etc.).
When this is detected, EDC sends
more torque to the rear wheels to
make sure all four wheels are
spinning at similar speeds, making
the vehicle more stable.
Competitive
Driving Mode
On vehicles with a V8 engine,
the driver can select this optional
handling mode by pressing the
StabiliTrak/TCS button two times
quickly while Traction Control and
StabiliTrak are turned on. When
the system is on, the StabiliTrak
Off light comes on and StabiliTrak
Competitive Mode will be displayed
in the Driver Information Center
(DIC). SeeRide Control System
