Trip Computer
The vehicle may have a trip
computer. The trip computer
provides information on driving data.
This information is continually
recorded and evaluated
electronically. If power has been
interrupted or if the battery voltage
has dropped too low, the values
stored in the trip computer will
be lost.
The trip computer main page
provides information on range and
instantaneous consumption.
To access other trip computer
vehicle data, do one of the following:
Press the BC button on the
audio system, if your vehicle has
this feature.
Press the left thumbwheel, if your
vehicle has this feature, on the
steering wheel.
Select the trip computer menu
front display.The functions are displayed in the
following order:
Range
This display shows the approximate
number of remaining miles (mi)
or kilometers (km) the vehicle can
be driven without refueling.
The message “Range” displays if
less than 31 miles (50 km) can
be driven with the fuel remaining
in the tank.
SeeDIC Warnings and Messages
(Base and Uplevel Systems) on
page 4-36for information on
acknowledging the message.
The fuel range estimate is based on
an average of the vehicle’s fuel
economy over recent driving history
and the amount of fuel remaining
in the fuel tank. This estimate
will change if driving conditions
change. For example, if driving in
traffic and making frequent
stops, this display may read one
number, but if the vehicle is drivenon a freeway, the number may
change even though the same
amount of fuel is in the fuel tank.
This is because different driving
conditions produce different
fuel economies. Generally, freeway
driving produces better fuel
economy than city driving.
Fuel range cannot be reset.
Instantaneous Consumption
This display shows the current fuel
economy at a particular moment and
will change frequently as driving
conditions change. This display
shows the instantaneous fuel
economy in miles per gallon (mpg) or
liters per 100 kilometers (l/100 km).
The metric display changes
depending on speed:
Below 8 mph (13 km/h),
displays in l/h.
Above 8 mph (13 km/h),
displays in l/100 km.
This screen cannot be reset.

DIC Warnings and
Messages (Base and
Uplevel Systems)
Messages are displayed on the DIC
to notify the driver that the status
of the vehicle has changed and that
some action may be needed by
the driver to correct the condition.
Multiple messages may appear one
after another.
The DIC monitors some uid levels,
battery of the Remote Keyless
Entry (RKE) transmitter, the
theft-deterrent system on vehicles
with this feature, the brake light
switch, and important exterior lights,
including wiring and fuses.Some messages may not require
immediate action, but you can
acknowledge that you received the
messages and to clear them
from the display by doing one of the
following:
Press the OK button on the base
level audio system.
Press the multifunction knob, if
your vehicle has this feature,
on the uplevel audio system.
Press the left thumbwheel, if your
vehicle has this feature, on the
steering wheel.
If there are several warning
messages, acknowledge them
one at a time.

Some messages cannot be cleared
from the DIC display because
they are more urgent. These
messages require action before they
can be cleared. You should take
any messages that appear on
the display seriously and remember
that clearing the messages will
only make the messages disappear,
not correct the problem.
Warning messages for the
uplevel DIC follow. On the base
level DIC, messages appear in an
abbreviated form.
Brakelight check---
This message displays when there
is a problem with the vehicle
lighting. The source of the problem
is displayed as text. For example,
“Brakelight check right”.
Brakelight switch check
This message displays when the
brake lamp does not come on when
the brake is applied. Have your
vehicle serviced by your
dealer/retailer immediately.
Coolant level check
This message displays when the
engine coolant level is low. Have the
cooling system serviced by your
dealer/retailer as soon as possible.
SeeEngine Coolant on page 9-16.
Remote Control Battery check
This message displays if the
Remote Keyless Entry (RKE)
transmitter battery is low. Replace
the battery in the transmitter.
See “Battery Replacement” under
Remote Keyless Entry (RKE)
System Operation on page 2-4.
Safeguard check
This message displays when there
is a problem with the theft-deterrent
system. Have the system serviced
by your dealer/retailer immediately.
Washer Fluid Level
(Base Level) or Washing
Water Level (Uplevel)
This message displays when the
vehicle’s windshield washer uid is
low. When the washer uid level
is low, the rear window washer
system is deactivated. Fill the
windshield washer uid reservoir
to the proper level as soon as
possible. SeeWindshield Washer
Fluid on page 9-20.

How OnStar Service Works
The OnStar system can record
and transmit vehicle information.
This information is automatically sent
to an OnStar Call Center when the
OnStar button is pressed, the
emergency button is pressed, or if
the airbags deploy. This information
usually includes the vehicle’s GPS
location and, in the event of a crash,
additional information regarding the
crash that the vehicle was involved
in (e.g. the direction from which
the vehicle was hit). When the
Virtual Advisor feature of OnStar
Hands-Free Calling is used, the
vehicle also sends OnStar the
vehicle’s GPS location so they can
provide services where it is located.
OnStar service cannot work unless
the 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 the vehicle is in
a place where the wireless serviceprovider 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.
Location information about the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.
The vehicle must have a working
electrical system, including adequate
battery power, for the OnStar
equipment to operate. There are
other problems OnStar cannot
control that may prevent OnStar
from providing OnStar service at
any particular time or place.
Some examples are damage to
important parts of the vehicle in a
crash, hills, tall buildings, tunnels,
weather or wireless phone network
congestion.Your Responsibility
Increase the volume of the radio if
the OnStar advisor cannot be heard.
If the light next to the OnStar
buttons is red, the system may not
be functioning properly. Press
the OnStar button and request a
vehicle diagnostic. If the light
appears clear (no light is appearing),
your OnStar subscription has
expired and all services have been
deactivated. Press the OnStar
button to con rm that the OnStar
equipment is active.

Radio Reception
Frequency interference and static
can occur during normal radio
reception if items such as cell phone
chargers, vehicle convenience
accessories, and external electronic
devices are plugged into the
accessory power outlet. If there is
interference or static, unplug the item
from the accessory power outlet.
AM
The range for most AM stations is
greater than for FM, especially
at night. The longer range can cause
station frequencies to interfere
with each other. For better radio
reception, most AM radio stations
boost the power levels during
the day, and then reduce these
levels during the night. Static
can also occur when things like
storms and power lines interfere
with radio reception. When this
happens, try reducing the treble on
your radio.
FM Stereo
FM stereo gives the best sound, but
FM signals reach only about 10 to
40 miles (16 to 65 km). Tall buildings
or hills can interfere with FM signals,
causing the sound to fade in and out.
Cellular Phone Usage
Cellular phone usage may cause
interference with the vehicle’s radio.
This interference may occur when
making or receiving phone calls,
charging the phone’s battery,
or simply having the phone on. This
interference causes an increased
level of static while listening to
the radio. If static is received while
listening to the radio, unplug the
cellular phone and turn it off.
Fixed Mast Antenna
The xed mast antenna can
withstand most car washes without
being damaged, or it can be
removed. If the mast should ever
become slightly bent, straighten
it out by hand. If the mast is badly
bent, replace it.
Check occasionally to make sure
the mast is still tightened to the
antenna base located on the roof of
the vehicle.
