2008 PONTIAC GRAND PRIX Owners Manual

The oil light could also come on in two other situations:
When the ignition is on but the engine is not
running, the light will come on as a test to indicate
it is working. The light will go out when the
engine is started. If it does not come on while the
ignition is in the on position, there may be a problem
with the fuse or bulb. SeeFuses and Circuit
Breakers on page 5-121.
If the brakes are applied quickly and the vehicle
makes a hard stop, the light may come on for a
moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.
Fog Lamp Light
The fog lamp light will
come on when the fog
lamps are in use.
The light will go out when the fog lamps are turned off.
SeeFog Lamps on page 3-18for more information.
Cruise Control Light
This light comes on
whenever you set the
cruise control.
The light goes out when the cruise control is turned off.
SeeCruise Control on page 3-12for more information.
3-53

Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-9
for more information.
Fuel Gage
The fuel gage shows
about how much fuel is
left in the fuel tank
when the ignition is on.
When the indicator nears empty, there is still a little fuel
left, but you should get more soon.
Here are four things owners usually ask about the fuel
gage. All these situations are normal and do not
indicate a problem with the fuel gage:
At the gas station the pump shuts off before the
gage reads full.
It takes more or less fuel to ll up than the gage
indicates. For example, the gage reads half full,
but it took more or less than half the tank’s capacity
to ll it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate full when the ignition is
turned off.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives important
safety and maintenance facts. When the vehicle’s
ignition is turned on, all of the DIC lights illuminate for a
few seconds and an introductory message will appear.
After this, the DIC will begin working.
DIC Operation and Displays
(Uplevel DIC with Trip Computer)
The Driver Information Center (DIC) control buttons and
the message display screen are located above the
radio. The DIC gives important safety and maintenance
facts concerning the vehicle. The status of many of
the vehicle’s systems along with driver personalization
menus and warning messages about the vehicle’s
systems may display on the DIC screen.
The outside temperature automatically appears on
the bottom right corner of the DIC display screen.
If the outside temperature is below 38°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
dealer/retailer.The vehicle’s shift lever position and the direction the
vehicle is traveling will also appear on the DIC screen.
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 3-65
for more information.
The buttons on the DIC trip computer are gages,
trip odometer, set/reset, options, and fuel.

Trip Odometer
3(Trip Odometer):Press this button to access the
Odometer, Trip Distances, AVERAGE SPEED, and
TIME ELAPSED modes.
Odometer:When the trip odometer button is pressed,
the rst menu displayed on the DIC screen is the
odometer reading, or cumulative mileage of the vehicle.
The odometer cannot be reset.
Press the trip odometer button again to advance to the
next menu.
Trip Distances:This menu shows the distances that
the vehicle has driven between specic points. The
trip odometer will record the number of miles up to
9,999.9 miles or 9 999.9 km travelled for up to two trips.
When 9,999.9 miles or 9 999.9 km is reached for either
trip, the odometer for that trip will go back to zero.
To reset the trip distances:
1. Press the trip odometer button again to access
TRIP A. Press the trip odometer button again to
access TRIP B. To reset the trip odometer(s) back to
zero miles or to zero kilometers, access the trip that
needs to be reset and press the set/reset button.
2. Press the trip odometer button again to advance
to the next screen.The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to
the number of miles (kilometers) driven since the
ignition was last turned on. This can be used if the
trip odometer is not reset at the beginning of the trip.
To use the retro-active reset feature, press and hold
the set/reset button for at least three seconds. The trip
odometer will display the number of miles or kilometers
driven since the ignition was last turned on and the
vehicle was moving. Once the vehicle begins moving,
the trip odometer will accumulate mileage. For example,
if the vehicle was driven 5.0 miles (8.0 km) before it
is started again, and then the retro-active reset feature
is activated, the display will show 5.0 miles (8.0 km).
As the vehicle begins moving, the display will then
increase to 5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after the
vehicle is started, but before it begins moving, the
display will show the number of miles or kilometers
that were driven during the last ignition cycle.
