Doors and Locks
Door Locks
{WARNING:
Unlocked doors can be dangerous.
•Passengers, especially children, can easily
open the doors and fall out of a moving vehicle.
When a door is locked, the handle will not open
it. The chance of being thrown out of the
vehicle in a crash is increased if the doors are
not locked. So, all passengers should wear
safety belts properly and the doors should be
locked whenever the vehicle is driven.
•Young children who get into unlocked vehicles
may be unable to get out. A child can be
overcome by extreme heat and can suffer
permanent injuries or even death from heat
stroke. Always lock the vehicle whenever
leaving it.
•Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
Locking your doors can help prevent this from
happening.

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

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 will not start in any other position. To restart
the engine when the vehicle is already moving,
use N (Neutral) only.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord for the engine coolant heater is located on
the driver side of the engine compartment and is
attached to the hose for the power steering reservoir.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts and prevent damage.The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.
Automatic Transmission Operation
(Six Speed Automatic Transmission)
Vehicles with a six speed automatic transmission
have a shift position indicator within the instrument
panel cluster.
There are several different positions for the shift lever.
See “Range Selection Mode” later in this section.
P (Park):This position locks the rear wheels. It is the
best position to use when starting the engine because the
vehicle cannot move easily. When parked on a hill,
especially when the vehicle has a heavy load, you might
notice an increase in the effort to shift out of P (Park).
See Torque Lock (Automatic Transmission) under
Shifting Into Park on page 3-36for more information.

{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park on page 3-36. If you are pulling a trailer, see
Towing a Trailer on page 5-26.
R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.To rock the vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 5-16.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use N (Neutral) only. Also, use
N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.

P (Park):This position locks your rear wheels. It is
the best position to use when you start the engine
because the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is

Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You must first
press the brake pedal before you can shift from P (Park)
with the ignition in ON/RUN.
If you cannot shift out of P (Park), ease pressure on the
shift lever and push the shift lever all the way into
P (Park) as you maintain brake application. Then move
the shift lever into another gear. SeeShifting Out of
