get out of the vehicle, keeping the door open.

lock the vehicle using the power door lock or the
RKE system and close the door. Wait 30 seconds
until the security lamp goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the hazard lights will ash.
You can turn off the alarm by unlocking the driver’s door

you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the

Ignition Positions
The ignition switch has four different positions:
In order to shift out of P (Park), ignition must be in the
ON/RUN or ACC/ACCESSORY and the brake pedal
must be applied.
Notice: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/retailer.A (LOCK/OFF):This is the only position in which the
ignition key can be inserted or removed. This position
locks the ignition and transmission and steering column.
The steering can bind with the wheels turned off
center. If this happens, move the steering wheel from
right to left while turning the key to ACC/ACCESSORY.
If this doesn’t work, the vehicle needs service.
B (ACC/ACCESSORY):This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN):This position is where the key returns to
after the vehicle is started. This position displays some
of the warning and indicator lights.
The battery could be drained if you leave the key in
the ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start the vehicle if the
battery is allowed to drain for an extended period of time.
D (START):This position starts the engine.
A warning chime will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN
when the driver door is opened if the ignition is in
LOCK/OFF, ACC/ACCESSORY and the key is in the
ignition. SeeDIC Warnings and Messages on page 3-73
for more information.

Mirrors
Automatic Dimming Rearview Mirror
The vehicle has an automatic dimming inside rearview
mirror with a compass display. The mirror may also
have OnStar
®controls and Intellibeam™. For more
information on Intellibeam™, see “Intellibeam Intelligent
High-Beam Headlamp Control System” underExterior
Lamps on page 3-29. For more information about
OnStar
®, seeOnStar®System on page 2-51.
Automatic Dimming Mirror Operation

behind the vehicle. The dimming feature comes on and
the indicator light illuminates each time the vehicle is
started.
O(On/Off):Press and holdOfor about three seconds
to turn the dimming feature and compass display on
or off.
AUTO
3(Vehicles with Intellibeam™):Press and

Compass
Compass Operation

to turn the compass on or off.
When the ignition and the compass feature are on, after
a few seconds, the mirror will display the compass
heading. The compass automatically calibrates as the
vehicle is driven.
Compass Calibration
If after a few seconds, the display does not show the
correct direction, (for example, N for North), there
may be a strong magnetic eld interfering with the
compass. Interference can be caused by a magnetic
antenna mount, magnetic note pad holder or a
similar magnetic item.
2-38
The front display is located on top of the instrument panel
to the right of the driver. The front display will have either
three or six lights to provide distance and system
information. With Adaptive Cruise control (ACC), it will
have three lights along with the ACC lights. Without ACC,
it will have six lights. High-toned beeps from the front
speakers are for objects detected near the front bumper.
The rear display is located near the rear window and can
be seen by looking over your right shoulder. The rear
display uses three color-coded lights to provide distance
and system information. Low-toned beeps from the rear
speakers are for the rear bumper.
How the System Works
UFRPA comes on automatically when the shift lever
is moved out of P (Park). The system does not
work at a forward or reverse speed greater than
5 mph (8 km/h).
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below hood or trunk level.
Objects must also be within 4 feet (1.2 m) in front of
the vehicle and 8 feet (2.5 m) from the rear bumper.
This distance may be less during warmer or humid
weather.
When backing up, if objects are detected at the same
time near both the front and rear bumpers, both
color-coded light displays will notify you of objects close
to each bumper. If there are objects detected near both
bumpers, the beeps will only be sounded to notify that
objects are close to the rear bumper. However, if while
the vehicle is backing up and an object comes within
1 ft (0.3 m) of the front bumper, and at the same time
there is another object further than 1 ft (0.3 m) from the
rear bumper, then the beeps will only be sounded to
notify you of the closer object that is near the front
bumper.
The system can be disabled using the Driver Information
Center (DIC). See “Parking Assist” underDIC Operation
and Displays on page 3-68for more information. Front Parking Assist
