Perimeter Lighting
Perimeter lighting provides a period of exterior vehicle
lighting. Perimeter lighting activates when the key
is removed from the ignition or the vehicle is unlocked
using the remote keyless entry transmitter. The
amount of time the exterior lamps will remain on can be
programmed using the Driver Information Center
(DIC). See “EXIT LIGHT DELAY” underDIC Vehicle
Personalization on page 3-71for additional information.

visor vanity lamps, if equipped, are accidently left on. If
any of these lamps are left on while the ignition is
off, they will automatically turn off after 10 minutes. The
lamps will not come back on again until one of the
following occurs:
The ignition is turned on.
The interior lamps control is turned off, then to
door or on.
Ultrasonic Rear Parking
Assist (URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help you
park while in REVERSE (R) and operates only at speeds
less than 3 mph (5 km/h). URPA can help you avoid
colliding with objects such as parked vehicles. The
system can detect objects 5 feet (1.5 m) behind your
vehicle and tell you how close those objects are to your
rear bumper.

Driver Information Center (DIC)
Your vehicle may have a Driver Information
Center (DIC).
All messages will appear in the DIC display located in
the instrument panel cluster, below the speedometer.
The DIC buttons are located on the center of the
instrument panel, below the center outlets.
The DIC comes on when the ignition is on. After a short
delay, the DIC on the uplevel vehicle will display the
WELCOME DRIVER (1 or 2) if a personalized key 1 or 2
is used, and then the information that was last
displayed before the engine was turned off.
The DIC on the base level vehicle displays the odometer
and trip odometers only.
The DIC on the uplevel vehicle displays the odometer,
trip odometers, fuel economy, trip computer, vehicle
system, and compass display information. It also
displays warning messages if a system problem is
detected. In addition, the DIC on the uplevel vehicle
displays phone numbers that are called using the
OnStar
®system, if equipped. SeeOnStar®System on
page 2-34.The outside air temperature automatically appears in
the bottom right corner of the uplevel DIC display when
viewing the trip/odometer screens, fuel screens and
some of the gages screens. If the outside air
temperature is at or below 37°F (3°C), the temperature
reading will toggle between displaying the outside
temperature and the word ICE for two minutes. If there
is a problem with the system that controls the
temperature display, the letters OC (open circuit) or SC
(short circuit) will appear on the display. If this occurs,
have the vehicle serviced by your GM dealer.
The DIC on the uplevel vehicle also allows some
features to be customized or personalized. SeeDIC
Vehicle Personalization on page 3-71for more
information.
DIC Operation and Displays
The DIC has different modes which can be accessed by
pressing the DIC buttons located on the center of the
instrument panel. Depending on whether your vehicle
has the base level or uplevel DIC, the buttons and
modes available will differ.
The buttons on the base level vehicle are the

Compass variance is the difference between the earth’s
magnetic north and true geographic north. If not
adjusted to account for compass variance, the compass
