Driving and Operating 137
A warning chime will sound when the driver
door is opened and the key is in the
ignition.
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. The transmission is also
unlocked in this position.
If the key is left in ON/RUN with the engine
off, the battery could drain and the vehicle
may not start.
3 (START) : This is the position that starts
the engine. When the engine starts, release
the key. The ignition returns to ON/RUN for
driving.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 0176.
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
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 light 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.

138 Driving and Operating
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 battery. Wait at least 15 seconds
between each try, to let the cranking
motor cool down.
2. If the engine does not start after five to 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.
.Press and release the cruise control SET-
button. Engine speed will be held at
approximately 1200 rpm.
When the fast idle is active, the Driver
Information Center (DIC) will display FAST
IDLE ON.
One of the following actions will turn off
the fast idle:
.Pressing the brake.
.Selecting the cruise control cancel button.
.Releasing the parking brake.

To rock the vehicle back and forth to get
out of snow, ice, or sand without damaging
the transmission, seeIf the Vehicle Is Stuck
0 131.
N : 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.
Caution
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
(Continued)
Caution (Continued)
warranty. Be sure the engine is not
running at high speed when shifting the
vehicle.
Caution
A transmission hot message may display
if the automatic transmission fluid is too
hot. Driving under this condition can
damage the vehicle. Stop and idle the
engine to cool the automatic
transmission fluid. This message clears
when the transmission fluid has cooled
sufficiently.
D : This position is for normal driving.
It provides the best fuel economy. If you
need more power for passing, and you are:
.Going less than about 55 km/h (35 mph),
push the accelerator pedal about
halfway down.
.Going about 55 km/h (35 mph) or more,
push the accelerator all the way down.
By doing this, the vehicle shifts down to
the next gear and has more power. D (Drive) can be used when towing a trailer,
carrying a heavy load, or driving on steep
hills. You might want to shift the
transmission to a lower gear selection if the
transmission shifts too often.
Downshifting the transmission in slippery
road conditions could result in skidding. See
“Skidding”
underLoss of Control 0128.
The vehicle has a shift stabilization feature
that adjusts the transmission shifting to the
current driving conditions in order to reduce
rapid upshifts and downshifts. This shift
stabilization feature is designed to
determine, before making an upshift, if the
engine is able to maintain vehicle speed by
analyzing things such as vehicle speed,
throttle position, and vehicle load. If the
shift stabilization feature determines that a
current vehicle speed cannot be maintained,
the transmission does not upshift and
instead holds the current gear. In some
cases, this could appear to be a delayed
shift, however the transmission is operating
normally.
The transmission uses adaptive shift
controls. Adaptive shift controls continually
compare key shift parameters to
pre-programmed ideal shifts stored in the
transmission’s computer. The transmission

Driving and Operating 145
When M (Manual Mode) is selected, the
transmission will downshift and a number
displays in the Driver Information
Center (DIC) next to the M indicating the
current gear.
This number is the highest gear that can be
used. However, the vehicle can automatically
shift to lower gears as it adjusts to driving
conditions. This means that all gears below
that number are available. When 5 (Fifth) is
selected, 1 (First) through 5 (Fifth) gears are
automatically shifted by the vehicle, but
6 (Sixth) cannot be used until the +/−
button on the shift lever is used to change
to the gear.
Grade Braking is not available when Range
Selection Mode is active. SeeTow/Haul
Mode 0145.
While using Range Selection Mode, cruise
control and the Tow/Haul Mode can
be used.
Caution
Spinning the tires or holding the vehicle
in one place on a hill using only the
accelerator pedal may damage the
transmission. The repair will not be

covered by the vehicle warranty. If the
vehicle is stuck, do not spin the tires.
When stopping on a hill, use the brakes
to hold the vehicle in place.
Tow/Haul Mode
If equipped, Tow/Haul Mode adjusts the
transmission shift pattern to reduce shift
cycling, providing increased performance,
vehicle control, and transmission cooling
when towing or hauling heavy loads. Turn the Tow/Haul Mode on and off by
pressing the button on the instrument
panel. When Tow/Haul is on, a light on the
instrument cluster will come on.
See
Tow/Haul Mode Light 078.
Also see “Tow/Haul Mode” underTowing
Equipment 0172.
Tow/Haul Mode Grade Braking
Tow/Haul Mode Grade Braking is only
enabled while the Tow/Haul Mode is
selected and the vehicle is not in the Range
Selection Mode. See “Tow/Haul Mode”listed
previously and Manual Mode0144.
Tow/Haul Mode Grade Braking assists in
maintaining desired vehicle speeds when
driving on downhill grades by using the
engine and transmission to slow the vehicle.
To disable or enable Tow/Haul Mode Grade
Braking within the current ignition key cycle,
press and hold the Tow/Haul button for
three seconds.

146 Driving and Operating
Brakes
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. SeeAntilock Brake System
(ABS) Warning Light 078.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing or feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.
Parking Brake
To set the parking brake: 1. Hold the regular brake pedal down.
2. Firmly push the parking brake pedal down. 3. The brake system warning light will
come on, if the ignition is on. See Brake
System Warning Light 077.
If you are towing a trailer and parking on a
hill, see Driving Characteristics and Towing
Tips 0160.
To release the parking brake: 1. Hold the regular brake pedal down.
2. Pull the handle with the parking brake symbol located just above the parking
brake pedal.
3. The brake system warning light will turn off, if the ignition is on.
Caution
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.
Driving with the parking brake applied will
cause a warning chime to sound and a
Driver Information Center (DIC) message
may display. Release the parking brake or
stop the vehicle.
