2007 PONTIAC GRAND PRIX trip computer

The compass is self-calibrating, which eliminates
the need to manually set the compass. However,
under certain circumstances, such as during a long
distance cross-country trip, it will be necessary
to compensate for compass variance and reset the
zone through the DIC. SeeDIC Compass
(Uplevel DIC) on page 198for more information.
The buttons on the DIC trip computer are gages,
trip odometer, set/reset, options, and fuel.

DIC Warnings and Messages
These messages display if there is a problem in
one of the vehicle’s systems. They override
any other mode or screen the Driver Information
Center (DIC) may be in.
Some messages can be cleared from the DIC
screen. In order to do this, the message must be
acknowledged. To acknowledge or clear the
message from the screen, press the set/reset
button on the DIC. SeeDIC Controls and Displays

cleared until the problem indicated by the warning
message is taken care of. When the problem
indicated by the message is resolved, it can be
acknowledged and the screen can be reset.
Be sure to take any message that appears on the
DIC screen seriously and remember that
clearing the messages that are able to be
acknowledged, will only make the message
disappear, not correct the problem.
A/C OFF FOR ENGINE PROTECTION
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. To avoid added strain on a hot
engine, the air conditioning compressor is
automatically turned off. When the coolant

been sent at the same time, press the set/reset
button. If a tire pressure message appears on the
DIC, stop as soon as you can. Have the tire
pressures checked and set to those shown on the
Tire Loading Information label. SeeTires on
page 400,Loading Your Vehicle on page 317, and
Ination - Tire Pressure on page 408. The DIC
display also shows the tire pressure values for the
front and rear tires by pressing the options
button. SeeDIC Controls and Displays (Base
Level DIC) on page 186orDIC Controls and
Displays (Uplevel DIC with Trip Computer)
on page 190. If the tire pressure is low, the low
tire pressure warning light comes on. SeeLow Tire
Pressure Warning Light on page 178for more
information.This message displays while the ignition is in
RUN. Press the set/reset button to acknowledge
this message and to clear it from the screen.

How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change the engine oil and lter based on vehicle
use. Anytime the oil is changed, reset the system
so it can calculate when the next oil change is
required. If a situation occurs where you change the
oil prior to a CHANGE OIL SOON message
appearing on the DIC, reset the system.
To reset the oil life system, after the oil has been
changed, use the following procedure:
1. Press the options button on the DIC until
ENGINE OIL MONITOR appears on the
DIC screen.
2. Press the set/reset button to reset the system.
The next screen indicates that the engine oil
monitor system has been reset.
If the vehicle is equipped with the trip computer
DIC, when the gage button is pressed and
the OIL LIFE REMAINING mode appears, it
should read 100 percent OIL LIFE
REMAINING.
3. Turn the key to OFF.If the CHANGE OIL SOON message comes back
on when you start your vehicle, the engine oil
life system has not reset. Repeat the procedure.What to Do with Used Oil
Used engine oil contains certain elements that
may be unhealthy for your skin and could
even cause cancer. Do not let used oil stay on
your skin for very long. Clean your skin and nails
with soap and water, or a good hand cleaner.
Wash or properly dispose of clothing or rags
containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil
products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from
the lter before disposal. Never dispose of oil by
putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If you have a problem properly disposing of
used oil, ask your dealer, a service station, or a
local recycling center for help.

For additional information and details about the
DIC operation and displays seeDIC Controls and
Displays (Base Level DIC) on page 186orDIC
Controls and Displays (Uplevel DIC with Trip
Computer) on page 190andDIC Warnings and
Messages on page 200.
During cooler weather conditions, the low tire
pressure warning light and the DIC warning
message may come on when the vehicle is rst
started and then turn off as you start to drive. This
could be an early indicator that the tire pressures
are getting low and need to be inated to the
proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those tires.)As an added safety
feature, your vehicle
has been equipped with
a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires is
signicantly
under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inate them to the proper
pressure. Driving on a signicantly under-inated
tire causes the tire to overheat and can lead to tire
failure. Under-ination also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure, even
if under-ination has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
