Automatic Transaxle Operation
Your automatic transaxle has a shift lever located on
the steering column.
PARK (P):This position locks your front wheels. It’s the
best position to use when you start your engine
because your vehicle can’t 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.
CAUTION: (Continued)
CAUTION: (Continued)
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 2-28. If you are pulling a trailer, see
Towing a Trailer on page 4-39.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transaxle
shift lock control system. You have to fully apply
your regular brakes before you can shift from PARK (P)
while the ignition 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 move the shift lever into
the gear you want. SeeShifting Out of Park (P) on
page 2-30.

SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). 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.
Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transaxle won’t shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.Parking Brake
This vehicle has a PUSH
TO RELEASE parking
brake pedal. To set
the parking brake, hold the
regular brake pedal
down with your right foot.
Push down the parking
brake pedal with your
left foot.
If the ignition is in RUN or OFF, the brake system
warning light will turn on while the parking brake is set.
The parking brake uses the brakes on the rear wheels.
To release the parking brake, hold the regular brake
pedal down and push the parking brake pedal with your
left foot. When you lift your left foot, the parking brake
pedal will follow it to the released position.
If you try to drive with the parking brake on, after about
20 feet (6.1 m) a chime will sound continuously until
you release the parking brake. Also, the brake light will
stay on until the parking brake is released.
2-27

Move the lever up as far as it will go.
3. Turn the ignition key to LOCK.
4. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Leaving Your Vehicle With the
Engine Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is rmly set before you leave it. After
you’ve moved the shift lever into PARK (P), hold
the regular brake pedal down. Then, see if you can
move the shift lever away from PARK (P) without rst
pulling it toward you. If you can, it means that the
shift lever wasn’t fully locked into PARK (P).
2-29

Torque Lock
If you are parking on a hill and you don’t shift your
transaxle into PARK (P) properly, the weight of
the vehicle may put too much force on the parking pawl
in the transaxle. You may nd it difficult to pull the
shift lever out of PARK (P). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into Park (P)
on page 2-28.
When you are ready to drive, move the shift lever out of
PARK (P)beforeyou release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transaxle, so you
can pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transaxle shift lock
control system which locks the shift lever in PARK (P)
when the ignition is in the LOCK position. In addition,
you have to fully apply your regular brakes before you
can shift from PARK (P) when the ignition is in RUN.
SeeAutomatic Transaxle Operation on page 2-25.
If you cannot shift out of PARK (P), ease pressure on
the shift lever and push the shift lever all the way up into
PARK (P) as you maintain brake application. Then,
move the shift lever into the gear you want.
If you ever hold the brake pedal down but still can’t shift
out of PARK (P), try this:
1. Turn the key to OFF. Open and close the driver’s
door to turn off the RAP feature. (There is no shift
interlock in this key position.)
2. Apply and hold the brake until the end of Step 4.
3. Shift the transaxle to NEUTRAL (N).
4. Start the vehicle and then shift to the gear you
want.
5. Have the system xed as soon as you can.

Mirror Operation
MIRROR:Press this button to turn on the automatic
dimming feature. Press it again to turn off the automatic
dimming feature.
O(On/Off):For mirrors equipped with OnStar®
controls, press and hold this button for several seconds
to turn on the automatic dimming feature. Press and
hold it again to turn the automatic dimming feature off.
The green indicator light will come on when this
feature is active. The automatic dimming feature will be
active each time the vehicle is started.
Compass Operation
COMPASS:Press this button once to turn the compass
on or off.
O(On/Off):For mirrors equipped with OnStar®controls,
press this button once to turn the compass on or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass heading (N for North, for
example), there may be a strong magnetic eldinterfering with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder or a similar magnetic item. If the letter
C should ever appear in the compass window, the
compass may need calibration.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
Mirrors equipped with OnStar
®controls can be placed
in calibration mode by pressing and holding the
on/off button untilaCisshown in the compass display.
Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. The mirror is
set in zone eight upon leaving the factory. It will be
necessary to adjust the compass to compensate for
compass variance if you live outside zone eight. Under
certain circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. If not adjusted to account for compass
variance, your compass could give false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the following zone map.

Sunroof
Your vehicle may be equipped with a sunroof. The
sunroof has both manual and express features
for opening the glass panel and sunshade.
The switch for the sunroof
is located on the headliner
between the sun visors.
The sunroof switch has a number of positions that
control the sunroof movement.
The switch will work only when the ignition is on or
when the RAP is active. See “Retained Accessory
Power (RAP)” underIgnition Positions on page 2-22.
Open:Press and hold the switch rearward to the
rst position to open the glass panel and sunshade. The
sunshade can also be opened manually.Comfort Stop:Press and release the switch rearward
to the second position to express open the glass
panel to the comfort stop position. The comfort stop
position is designed to help reduce noise and make
passengers more comfortable.
Express Open:When the glass panel is express
opening, pressing the switch in any direction will stop it
in a partially-opened position. The glass panel may
be fully opened by pressing the switch rearward again.
If you press and hold the switch in the express open
position for more than one and a half seconds, the
express open operation will be overridden and
the sunroof will operate manually.
Close:To close the glass panel, press and hold the
switch forward. As the glass panel reaches the closed
position, it will open slightly toward the vent position and
then drop down to the closed position to provide a
better seal. The sunshade must be closed manually.
Vent:Once the sunroof is closed, it can be opened to
the vent position by pushing the switch upward. To
close the glass panel, pull the switch downward. The
sunshade must be opened and closed manually for vent
operation.

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press SET/COAST, then release it and the
accelerator pedal. You will now cruise at the
higher speed.
Press RESUME/ACCEL. Hold it there until you get
up to the speed you want, and then release it. To
increase your speed in very small amounts,
briey press RESUME/ACCEL and then release it.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
The accelerate feature will only work after you have set
the cruise control speed by pressing SET/COAST.
Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
Press SET/COAST until you reach the lower speed
you want, then release it.
To slow down in very small amounts, push
SET/COAST briey. Each time you do this, you’ll go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may have to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Applying the
brake or shifting into a lower gear will take your vehicle
out of cruise control. If you need to apply the brake
or shift to a lower gear due to the grade of the downhill
slope, you may not want to attempt to use your
cruise control feature.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal.
Press ON/OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
