Memory Seat, Mirrors, and Pedals
If your vehicle has this
feature, the controls for
the memory function
are located on the
driver’s door.
These buttons are used to program and recall
memory settings for the driver’s seating position,
both outside mirror positions, and the adjustable
pedals, if equipped. The settings for these features
can be saved for up to two drivers.
To store the memory settings, do the following:
1. Adjust the driver’s seat, including the seatback
recliner and lumbar, both of the outside
mirrors, and the adjustable pedals, if
equipped, to the desired position.
SeeAdjustable Throttle and Brake Pedal
on page 116for more information.2. Press and hold the 1 or 2 button of the
memory control for three seconds. A
double chime will sound to let you know
that the position has been stored.
To repeat the procedure for a second driver,
follow the preceding steps, but press the other
numbered memory control button.
To recall the memory settings, do one of the
following:
Press and release button 1 or 2 while the
vehicle is in PARK (P). A single chime
will sound and the memory position will be
recalled.
If programmed to do so through the Driver
Information Center (DIC), pressing the
unlock button on the remote keyless entry
transmitter will recall the preset driver’s
memory seat, mirrors, and adjustable pedals
position. The numbers on the back of the
transmitters, 1 or 2, correspond to the numbers
on the memory controls.
If programmed to do so through the DIC,
placing the key in the ignition will recall
the driver’s memory seat, mirrors, and
adjustable pedals positions.

If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.
If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light
comes on, you will be able to restart the engine if
you turn the engine off. However, your
Passlock
®system is not working properly and
must be serviced by your dealer. Your vehicle is
not protected by Passlock
®at this time. You
may also want to check the fuse. SeeFuses and
Circuit Breakers on page 493. See your dealer
for service.
In an emergency, call the GM Roadside
Assistance Center. SeeRoadside Assistance
Program on page 532.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Keep your speed at 55 mph (88 km/h)
or less for the rst 500 miles (805 km).
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake, or slow, the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 362for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.

Adjustable Throttle and Brake Pedal
If your vehicle has this feature, you can change the
position of the throttle and brake pedals. This
feature is designed for shorter drivers, since the
pedals cannot move farther away from the standard
position, but can move closer for better pedal reach.
If your vehicle has this feature, it can be
programmed to work with the memory function.
SeeMemory Seat, Mirrors, and Pedals on page 12.
The vehicle must be in PARK (P) for this feature
to operate.
The switch used to
adjust the pedals is
located on the steering
column.
Press the switch forward or backward to move the
pedals closer or farther away from you.
Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder,
the engine coolant heater can help. You will get
easier starting and better fuel economy during
engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C), use of
the coolant heater is not required. Your vehicle
may also have an internal thermostat in the
plug end of the cord. This will prevent operation of
the engine coolant heater when the temperature
is at or above 0°F (−18°C) as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the driver’s
side of the engine compartment next to the
battery box facing the engine.
3. Plug it into a normal, grounded 110-Volt AC
outlet.
116

Automatic Transmission Operation
There are several different positions for your gear
shift lever.
PARK (P):This position locks the rear wheels.
It is the best position to use when you start the
engine because your vehicle cannot move easily.
{CAUTION:
It is dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P)
with the parking brake rmly set. Your
vehicle can roll.
Do not leave your 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 your vehicle will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P).
SeeShifting Into Park (P) on page 127.
If you are pulling a trailer, seeTowing a
Trailer on page 362.
118

{CAUTION:
If you have four-wheel drive, your vehicle
will be free to roll — even if your shift
lever is in PARK (P) — if your transfer
case is in NEUTRAL. So, be sure the
transfer case is in a drive gear — not in
NEUTRAL. SeeFour-Wheel Drive on
page 122. SeeShifting Into Park (P) on
page 127.
Make sure the shift lever is fully in PARK (P)
before starting the engine. Your vehicle has an
automatic transmission shift lock control system.You have to fully apply the regular brakes rst and
then press the shift lever button before you can
shift from PARK (P) when the ignition key is
in RUN. If you cannot shift out of PARK (P), ease
pressure on the shift lever and push the shift
lever all the way into PARK (P) as you maintain
brake application. Then press the shift lever button
and move the shift lever into another gear. See
Shifting Out of Park (P) on page 129.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transmission. The repairs would not be covered
by your warranty. Shift to REVERSE (R) only
after your vehicle is stopped.
To rock your vehicle back and forth to get out of
snow, ice, or sand without damaging your
transmission, seeIf Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 348.
119

NEUTRAL (N):In this position, the engine does
not connect with the wheels. To restart when
you are already moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while your
engine is running at high speed is
dangerous. Unless your foot is rmly on
the brake pedal, your vehicle could move
very rapidly. You could lose control and
hit people or objects. Do not shift into a
drive gear while your engine is running at
high speed.
Notice:Shifting out of PARK (P) or
NEUTRAL (N) with the engine running at high
speed may damage the transmission. The
repairs would not be covered by your warranty.
Be sure the engine is not running at high
speed when shifting your vehicle.DRIVE (D):This position is for normal driving.
It provides the best fuel economy for your vehicle.
If you need more power for passing, and you are:
Going less than about 35 mph (55 km/h), push
the accelerator pedal about halfway down.
Going about 35 mph (55 km/h) or more, push
the accelerator all the way down.
You will shift down to the next gear and have
more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
underLoss of Control on page 318.
DRIVE (D) can be used when towing a trailer,
carrying a heavy load, driving on steep hills, or
for off-road driving. You may want to shift the
transmission to THIRD (3) or, if necessary, a lower
gear selection if the transmission shifts too often.
THIRD (3):This position is also used for normal
driving. It reduces vehicle speed more than
DRIVE (D) without using your brakes. You might
choose THIRD (3) instead of DRIVE (D) when
driving on hilly, winding roads, when towing
a trailer, so there is less shifting between gears
and when going down a steep hill.
120

To shift to the THIRD (3) position, you must rst
press the large button on the shift handle.
While the button is pressed, move the shifter in
the THIRD (3) position.
SECOND (2):This position reduces vehicle speed
even more than THIRD (3) without using your
brakes. You can use SECOND (2) on hills. It can
help control your speed as you go down steep
mountain roads, but then you would also want to
use your brakes off and on.
To shift to the SECOND (2) position, you must rst
press the large button on the shift handle. While
the button is pressed, move the shifter in the
SECOND (2) position.
You can also use SECOND (2) for starting the
vehicle from a stop on slippery road surfaces.FIRST (1):This position reduces vehicle speed
even more than SECOND (2) without using
your brakes. You can use it on very steep hills, or
in deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transmission will not shift into rst gear until the
vehicle is going slowly enough.
To shift to the FIRST (1) position, you must rst
press the large button on the shift handle.
While the button is pressed, move the shifter in
the FIRST (1) position.
Notice: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
your warranty. If you are stuck, do not spin
the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.
121

4m(Four-Wheel High):This setting should be
used when you need extra traction, such as
on snowy or icy roads or in most off-road
situations. This setting also engages your front
axle to help drive your vehicle.
4
n(Four-Wheel Low):This setting also
engages your front axle and delivers extra torque.
It sends maximum power to all four wheels.
You might choose this setting if you are driving
off-road in deep sand, deep mud, and climbing or
descending steep hills.
{CAUTION:
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P). You or
someone else could be seriously injured.
Be sure to set the parking brake before
placing the transfer case in NEUTRAL.
SeeParking Brake on page 126.NEUTRAL:Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle.
SeeRecreational Vehicle Towing on page 355for
more information.
An indicator light in the knob will show you which
position the transfer case is in. The indicator
lights will come on briey when you turn on the
ignition and one will stay on. If the lights do
not come on, you should take your vehicle to your
dealer for service. An indicator light will ash
while shifting the transfer case. It will stay on when
the shift is complete. If for some reason the
transfer case cannot make a requested shift, it will
return to the last chosen setting.
If the service Four-Wheel Drive Warning Light on
the instrument panel cluster stays on, you
should take your vehicle to your dealer for service.
SeeService Four-Wheel Drive Warning Light on
page 216for further information.
123

If the knob is turned to Four Wheel-High, Auto
Four-Wheel Drive, or Two-Wheel High when your
vehicle is in gear and/or moving, the Four-Wheel
High, Auto Four-Wheel Drive, or Two-Wheel
High indicator light will ash for 30 seconds. It will
not complete the shift unless your vehicle is
moving less than 2 mph (3.2 km/h) with the
transmission in NEUTRAL (N).
Shifting into NEUTRAL
Before shifting the transfer case to NEUTRAL, rst
make sure the vehicle is parked so that it will
not roll.
1. Set the parking brake.
2. Start the vehicle.
3. Put the transmission in NEUTRAL (N).
4. Shift the transfer case to Two-Wheel High.
5. Turn the transfer case knob all of the way past
Four-Wheel Low and hold it there for a
minimum of 10 seconds. The neutral indicator
light will come on.
6. With the engine running, shift the transmission
to REVERSE (R) for one second, then shift the
transmission to DRIVE (D) for one second, to
ensure that the transfer case is in NEUTRAL.7. Turn the engine off, by turning the key to
ACCESSORY.
8. Place the transmission shift lever in PARK (P).
9. Turn the ignition to LOCK.
Shifting Out of NEUTRAL
To shift the transfer case out of NEUTRAL, do the
following:
1. Set the parking brake and apply the regular
brake pedal.
2. Turn the ignition to RUN with the engine off.
3. Put the transmission in NEUTRAL (N).
4. Turn the transfer case knob to the desired
position (Two-Wheel High, Four-Wheel
High, or Auto Four-Wheel Drive).
5. After the transfer case has shifted out of
NEUTRAL, the indicator light will go out.
6. Release the parking brake.
7. Start the engine and shift the transmission to
the desired position.
