Replacing Restraint System Parts
After a Crash
{WARNING:
A crash can damage the restraint systems in your
vehicle. A damaged restraint system may not
properly protect the person using it, resulting in
serious injury or even death in a crash. To help
make sure your restraint systems are working
properly after a crash, have them inspected and
any necessary replacements made as soon as
possible.If the vehicle has been in a crash, do you need new
safety belts or LATCH system (if equipped) parts?
After a very minor crash, nothing may be necessary.
But the safety belt assemblies that were used during any
crash may have been stressed or damaged. See your
dealer/retailer to have the safety belt assemblies
inspected or replaced.
If the vehicle has the LATCH system and it was being
used during a crash, you may need new LATCH system
parts.
New parts and repairs may be necessary even if the
safety belt or LATCH system (if equipped), was
not being used at the time of the crash.
If an airbag inflates, you will need to replace airbag
system parts. See the part on the airbag system earlier
in this section.
Have the safety belt pretensioners checked if the
vehicle has been in a crash, if the airbag readiness light
stays on after the vehicle is started, or while you are
driving. SeeAirbag Readiness Light on page 4-23.

Power Windows
{WARNING:
Leaving children in a vehicle with the keys is
dangerous for many reasons, children or others
could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function and they could be seriously injured or
killed if caught in the path of a closing window.
Do not leave keys in a vehicle with children.
When there are children in the rear seat use the
window lockout button to prevent unintentional
operation of the windows.If the vehicle has power
windows, the controls are
located on each of the
side doors.
The driver door has a switch for the passenger window
also. The power windows will work when the ignition has
been turned to ON/RUN or ACC/ACCESSORY, or when
Retained Accessory Power (RAP) is active. SeeRetained
Accessory Power (RAP) on page 3-23.
Press the switch to lower the window.
Pull up on the front edge of the switch to raise the
window.
Express-Down
The driver window switch also has an express-down
feature that allows the window to be lowered without
holding the switch. Press fully and release the window
switch marked AUTO to activate the express-down mode.
This mode can be cancelled at any time by pulling up on
the switch. To open the window part way, lightly tap the
switch until the window is at the desired position.

B (ACC/ACCESSORY):This is the position in which
you can operate things like the radio and the windshield
wipers when the engine is off.
C (ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The
switch stays in this position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle
if the battery is allowed to drain for an extended period
of time.
D (START):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
•Audio System
•Power Windows (if equipped)
These features will work when the ignition key is in
ON/RUN or ACC/ACCESSORY. Once the key is turned
from ON/RUN to LOCK/OFF, power to the radio will
continue to work 10 minutes or until the driver door is
opened. The power windows will continue to work for up
to 10 minutes or until any door is opened.
Starting the Engine
If the vehicle has the DURAMAX®Diesel engine, see
the DURAMAX®Diesel manual for more information.
To place the transmission in the proper gear:
Move the shift lever to P (Park) or N (Neutral). The

engine when the vehicle is already moving, use
N (Neutral) only.

Cruise Grade Braking (Six Speed
Automatic Transmission)
Cruise Grade Braking operates only while cruise control
is engaged in Tow/Haul mode. Cruise Grade Braking
assists in maintaining desired vehicle speeds when
driving on downhill grades in cruise control by
automatically shifting to lower gears when the cruise set
speed is exceeded.
While in the Range Selection Mode (RSM) mode, cruise
grade braking is not available.
SeeAutomatic Transmission Operation (Six Speed
Automatic Transmission) on page 3-27orAutomatic
Transmission Operation (Four Speed Automatic
Transmission) on page 3-32.
Parking Brake

then push down the parking brake pedal.
If the ignition is on, the brake system warning light will
come on.

pedal down. Pull the handle, located just above
the parking brake pedal, with the parking brake symbol,
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. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
