2004 PONTIAC GRAND PRIX battery

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 you 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 your vehicle's
systems may display on the DIC screen.
The outside temperature automatically appears on the
bottom right corner of the DIC display screens. If the
outside temperature is below 38ÉF (3ÉC), 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.
The vehicle's transaxle 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. See ªSetting the Compassº later in this section
for more information.
The buttons on the DIC trip computer are:

REMAINING, this means that 99 percent of the current
oil life remains. When the oil life drops below ®ve
percent, the CHANGE OIL SOON message will appear
on the display. The engine oil should be changed
within 200 miles. Be sure to keep a record of the
mileage and date of the oil change so you will have it
for future reference.
Never drive the vehicle more than 10,000 miles
(16 000 km) or 12 months (whichever comes ®rst)
without an oil change.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get
and it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can.
To help keep warm, you can get out of the vehicle
and do some fairly vigorous exercises every half hour
or so until help comes.If You Are Stuck: In Sand, Mud,
Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you don't want to spin your
wheels too fast. The method known as ªrockingº can
help you get out when you're stuck, but you must
use caution.
{CAUTION:
If you let your tires spin at high speed, they can
explode, and you or others could be injured.
And, the transaxle or other parts of the vehicle
can overheat. That could cause an engine
compartment ®re or other damage. When you're
stuck, spin the wheels as little as possible.
Don't spin the wheels above 35 mph (55 km/h)
as shown on the speedometer.
