174 Driving and Operating
Ignition Positions
The ignition switch has four different
positions.
To shift out of P (Park), the ignition
must be on or in ACC/ACCESSORY
and the regular brake pedal applied.
0 (STOPPING THE ENGINE/LOCK/
OFF) :When the vehicle is stopped,
turn the ignition switch to LOCK/
OFF to turn the engine off. Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) 0177.
This position locks the ignition and
transmission. Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop, shift to P (Park), and turn the
ignition off. On vehicles with an
automatic transmission, the
shift lever must be in P (Park)
to turn the ignition switch to the
LOCK/OFF position.
4. Set the parking brake. See Parking Brake 0187.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
turn the ignition to ACC/
ACCESSORY.
Caution
Using a tool to force the key to
turn in the ignition could cause
damage to the switch or break the
key. Use the correct key, make
sure it is all the way in, and turn it
only with your hand. If the key
cannot be turned by hand, see
your dealer.

Driving and Operating 175
1 (ACC/ACCESSORY) :This is the
position in which you can operate
things like the radio and the
windshield wipers when the engine
is off.
2 (ON/RUN) : This position can be
used to operate the electrical
accessories and to display some
instrument cluster warning and
indicator lights. This position can
also be used for service and
diagnostics, and to verify the proper
operation of the malfunction
indicator lamp as may be required
for emission inspection purposes.
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.
3 (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.
Starting the Engine
If the vehicle has a diesel engine,
see the Duramax diesel
supplement.
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.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
See
Add-On Electrical Equipment
0 212.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
while starting the vehicle, damage
may occur to the hydraulic power
steering system and there may be
loss of power steering assist.
Starting Procedure 1. With your foot off the accelerator pedal, turn the
ignition key to START. When
the engine starts, let go of the
key. The idle speed will go
down as your engine gets
warm. Do not race the engine

176 Driving and Operating
immediately after starting it.
Operate the engine and
transmission gently to allow the
oil to warm up and lubricate all
moving parts.
When the Low Fuel warning
lamp is on and the FUEL
LEVEL LOW message is
displayed in the Driver
Information Center (DIC), the
Computer-Controlled Cranking
System is disabled to prevent
possible vehicle component
damage. When this happens,
hold the ignition switch in the
START position to continue
engine cranking.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the(Continued)
Caution (Continued)
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after 5-10 seconds, especially
in very cold weather (below
−18 °C or 0 °F), it could be
flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you hold the key in START for
up to 15 seconds. Wait at least
15 seconds between each try,
to allow the cranking motor to
cool down. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briefly but then stops again, do
the same thing. This clears the
extra gasoline from the engine.
Do not race the engine
immediately after starting it.
Operate the engine and transmission gently until the oil
warms up and lubricates all
moving parts.
Fast Idle System
If equipped, this feature is available
only with cruise control. The manual
fast idle switch is operated using the
cruise control buttons on the left
side of the steering wheel.
This system can be used to
increase engine idle speed
whenever the following conditions
are met:
.
The parking brake is set.
. The brake pedal is not pressed.
. The vehicle must not be moving
and the accelerator must not be
pressed.
To control the fast idle:
. To enable the Fast Idle System,
press and release the cruise
control on/off button and ensure
that the switch indicator light
is lit.

Shifting Into Park
1. Hold the brake pedal down,then set the parking brake.
2. Move the shift lever into the P (Park) position by pulling the
shift lever toward you and
moving it up as far as it will go.
3. Turn the ignition off.
4. Remove the key and take it with you. If you can leave the
vehicle with the ignition key in
your hand, the vehicle is
in P (Park).
Leaving the Vehicle with the
Engine Running
{Warning
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
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.
(Continued)
Warning (Continued)
Do not leave the vehicle when the
engine is running. 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 0179.
If you are towing a trailer, see
Driving Characteristics and
Towing Tips 0202.
If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is firmly set. After the
shift lever is moved into P (Park),
hold the regular brake pedal down.
Then, see if you can move the shift
lever away from P (Park) without
first pulling it toward you. If you can,
it means that the shift lever was not
fully locked into P (Park).
Torque Lock
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of the
vehicle can put too much force on
the parking pawl in the
transmission. It might be difficult to
pull the shift lever out of P (Park).
This is called torque lock. To
prevent torque lock, set the parking
brake and then shift into P (Park)
properly before you leave the driver
seat. To find out how, see Shifting
Into Park 0179.
When you are ready to drive, move
the shift lever out of P (Park) before
releasing the parking brake.
If torque lock does occur, you might
need to have another vehicle push
yours a little uphill to take some of
the pressure from the parking pawl
in the transmission. Then you
should be able to pull the shift lever
out of P (Park).
