Shifting Into Park (P)
{CAUTION:
It can be 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. 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,
use the steps that follow. If you are
pulling a trailer, seeTowing a Trailer on
page 315.
Steering Column Shift Lever
If your vehicle has a steering column shift lever,
use the following procedure to shift the vehicle into
PARK (P):
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pulling
the shift lever toward you and moving it up as
far as it will go.
3. With your right foot still holding the brake
pedal down, set the parking brake. See
Parking Brake on page 122for more
information.
4. Turn the ignition key to OFF.
5. 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).
123

Console Shift Lever
If your vehicle is equipped with a console shift
lever, use the following procedure to shift
the vehicle into PARK (P):
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pushing
the lever all the way toward the front of your
vehicle and then to the left.
3. With your right foot still holding the brake
pedal down, set the parking brake. See
Parking Brake on page 122for more
information.
4. Turn the ignition key to OFF.
5. 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. SeeParking Brake on page 122for more
information.
124

Torque Lock
If you are parking on a hill and you do not 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 123.
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. You have to fully apply your regular
brakes before you can shift from PARK (P) when
the ignition is RUN. SeeAutomatic Transaxle
Operation on page 119.
The shift lock control system is designed to do the
following:
Prevent the ignition key from being removed
unless the shift lever is in PARK (P).
Prevent movement of the console shift lever
out of PARK (P) unless the ignition is in a
position other than OFF.
The shift lock control system is always functional
except in the case of a dead battery or low
voltage (less than 9 V) battery.
If you cannot shift out of PARK (P), ease the
pressure on the shift lever. 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.
If you are still having a problem shifting, then have
your vehicle serviced soon.
125

Running the Engine While Parked
It is better not to park with the engine running. But if
you ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust
into your vehicle. See the earlier caution
underEngine Exhaust on page 127.
Also, idling in a closed-in place can let
deadly carbon monoxide (CO) into your
vehicle even if the climate control fan is
at the highest setting. One place this can
happen is a garage. Exhaust — with
CO — can come in easily. NEVER park
in a garage with the engine running.
Another closed-in place can be a blizzard.
SeeWinter Driving on page 302.
{CAUTION:
It can be 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).
Follow the proper steps to be sure your vehicle
will not move. SeeShifting Into Park (P) on
page 123.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 315.

130

Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. If the
mirror is not adjusted for compass variance, the
compass could give false readings.
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 the
vehicle is driven outside zone eight. Under
certain circumstances, such as a long distance,
cross-country trip, it will be necessary to adjust the
compass variance.
To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the zone map. SeeAutomatic
Dimming Rearview Mirror with OnStar
®and
Compass on page 130for map information.
2. Press and hold the on/off button until a zone
number appears on the display.
3. Once the zone number appears on the display,
press the on/off button quickly until you reach
the correct zone number. If C or CAL appears
in the compass window, the compass may
need calibration. See “Compass Calibration”
listed previously.

outside mirror so that you can see a little of your
vehicle, and the area behind your vehicle.
The mirrors may also have an arrow that ashes
when the turn signal is used. SeeTurn and
Lane-Change Signals on page 162.
133

Outside Curb View Assist Mirror
If your vehicle is equipped with memory mirrors, it
will also be capable of performing the curb view
assist mirror feature. This feature will allow the
driver’s and passenger’s side mirror to tilt to a
factory programmed position when the vehicle
is in REVERSE (R). This feature may be useful in
allowing you to view the curb when you are parallel
parking.
When the vehicle is shifted out of REVERSE (R)
or the ignition is turned to off, the driver’s and
passenger’s side mirror will return to its original
position.
SeeDIC Vehicle Customization on page 231for
more information.
Outside Convex Mirror
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be
seen from the driver’s seat.
{CAUTION:
A convex mirror can make things (like
other vehicles) look farther away than
they really are. If you cut too sharply into
the right lane, you could hit a vehicle on
your right. Check your inside mirror or
glance over your shoulder before
changing lanes.
134

Outside Automatic Dimming
Heated Mirror

recording and transmitting vehicle information.
This information is automatically sent to an OnStar
®
Call Center at the time of an OnStar®button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually
includes your GPS location and, in the event of a
crash, additional information regarding the accident
that your vehicle has been involved in (e.g. the
direction from which your vehicle was hit). When
you use the Virtual Advisor feature of OnStar
®
Hands-Free Calling, your vehicle also sends
OnStar®your GPS location so that we can
provide you with location-based services.
OnStar
®service cannot work unless your vehicle is
in a place where OnStar®has an agreement with a
wireless service provider for service in that area.
OnStar
®service also cannot work unless you
are in a place where the wireless service provider
OnStar
®has hired for that area has coverage,
network capacity and reception when the service is
needed, and technology that is compatible with the
OnStar
®service. Not all services are available
everywhere, particularly in remote or enclosed
areas, or at all times.
