To release the parking brake,
hold the regular brake pedal down.
Pull the bottom edge of the lever,
located above the parking brake
pedal, with the parking brake
symbol, directly rearward to
release the parking brake.
If the ignition is on when the parking
brake is released, the brake system
warning light will go off.
Notice:Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
If you are towing a trailer and are
parking on any hill, see Driving
Characteristics and Towing Tips on
page 9‑54.Brake Assist
This vehicle has a brake assist
feature 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 the
brake pedal is released or brake
pedal pressure is quickly
decreased.

9-44 Driving and Operating
Ride Control Systems
Traction Control
System (TCS)
The Traction Control System (TCS)
is part of StabiliTrak. TCS limits
wheel slip which is especially useful
in slippery road conditions. The
system operates only if it senses
that any of the wheels are spinning
or beginning to lose traction. When
this happens, TCS applies the
brakes to limit wheel spin and also
reduces engine power. The system
may be heard or felt while it is
working. This is normal and does
not mean there is a problem with
the vehicle.
Notice:If the wheel(s) of one axle
is allowed to spin excessively
while the StabiliTrak
®, ABS, brake
warning lights, and any relevant
DIC messages are displayed, the
transfer case could be damaged.
The repairs would not be covered
by the vehicle warranty. Reduce
engine power and do not spin the wheel(s) excessively while these
lights and messages are
displayed.
TCS can operate on dry roads
under some conditions. When this
happens, the system may be
heard working or a reduction in
acceleration may be noticed. This is
normal and does not mean there is
a problem with the vehicle.
Examples of these conditions
include hard acceleration in a turn,
an abrupt upshift or downshift of the
transmission or driving on rough
roads.
If cruise control is being used
when TCS begins to limit wheel
spin, the cruise control automatically
disengages. The cruise control
can be re-engaged when road
conditions allow. See
Cruise Control
on page 9‑47.
The message TRACTION FAULT
appears in the Driver Information
Center (DIC) when a TCS or
Antilock Brake System (ABS)
problem has been detected and the vehicle needs service. When
this message is on, the system will
not limit wheel spin. Adjust your
driving accordingly. See
Ride
Control System Messages on
page 5‑26.
The TCS/StabiliTrak light will flash
on the instrument panel cluster
when the TCS system or StabiliTrak
is both on and activated.
The TCS/StabiliTrak button is
located on the instrument panel.

Driving and Operating 9-57
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at
a lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with an
automatic transmission in P (Park)
or a manual transmission in
N (Neutral) with the parking brake
applied, for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating on page 10‑23.Parking on Hills
{WARNING
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet for
vehicles with an automatic
transmission, or into gear for
vehicles with a manual
transmission. Turn the wheels
into the curb if facing downhill or
into traffic if facing uphill. 2. Have someone place chocks
under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park) for vehicles with an
automatic transmission or into
gear for vehicles with a manual
transmission.
5. If the vehicle has four-wheel-drive, be sure the
transfer case is in a drive gear
and not in N (Neutral). See
Four-Wheel Drive on page 10‑30
for more information.
6. Release the brake pedal.

Front Position
If the flat tire is on the front of
the vehicle, position the jack to
the rear of the front tire in the
pocket off of the frame.Rear Position
If the flat tire is on the rear,
position the jack under the rear
axle and get as close as
possible to the shock absorber.
5. Make sure the jack head is positioned so that the rear axle
is resting securely between the
grooves that are on the
jack head. 6. Turn the wheel wrench
clockwise to raise the vehicle.
Raise the vehicle far enough off
the ground so there is enough
room for the spare tire to fit
under the wheel well.
7. Remove all the wheel nuts andthe flat tire.
