engine oil PONTIAC GRAND PRIX 2005 Owners Manual

If the vehicle is left running it will automatically shut off
after 10 minutes unless a time extension has been
done. To manually shut off a remote start, do any of
the following:
Aim the remote keyless entry transmitter at the
vehicle and press the remote start button until
the parking lamps turn off.
Turn on the hazards warning ashers.
Turn the ignition switch on and then off.
The remote start feature provides two separate starts,
each with 10 minutes of engine running, or it provides
one start with 10 minutes of engine running which may
be extended by 10 more minutes. If you press and
release the transmitter lock button and then press and
hold the remote start button, on the keyless entry
transmitter, again before the rst 10 minutes of the
engine running time has expired, 10 minutes are added
to the remaining minutes. For example, if the lock
and then the remote start buttons are pressed again
after ve minutes of the engine run time, 10 minutes
are added and you now have 15 minutes of the
engine running. The added 10 minutes is considered
a second start. Once two remote starts or a single start
with a time extension have been provided, the vehicle
must be started normally with the ignition key to
get more remote starts.The remote start feature will not operate if the key is in
the ignition, a door is open or the hood is not closed.
The remote start feature will not operate if there is
an emission control system malfunction. Also, the engine
will turn off during a remote vehicle start if the coolant
temperature gets too high or the oil pressure gets low.
If a remote start is attempted and unsuccessful, the
Driver Information Center (DIC) will display REMOTE
START DISABLED.

Engine Coolant Heater
The vehicle may be equipped with an engine coolant
heater. In very cold weather, 0°F (−18°C) or colder, the
engine coolant heater can help. The vehicle will start
easier and get better fuel economy during engine
warm-up. Usually, the coolant heater should be plugged
in a minimum of four hours prior to starting the
vehicle. At temperatures above 32°F (0°C), use of the
coolant heater is not required. Your vehicle may
also have an internal thermostat in the plug end of the
cord. This will prevent operation of the engine coolant
heater when the temperature is at or above 0°F (−18°C)
as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located above the engine air cleaner/lter.
SeeEngine Compartment Overview on page 5-12
for more information on location.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before, making sure to
keep it away from moving engine parts. If this is
not done, the cord could be damaged.
How long should the coolant heater be kept plugged in?
The answer depends on the outside temperature, the
kind of oil that is in the vehicle, and some other things.
Instead of trying to list everything here, we ask that
you contact your dealer in the area where the vehicle will
be parked. The dealer can give you the best advice
for that particular area.

Oil Pressure Light
If there is a problem with
the vehicle’s oil pressure,
this light may stay on
when the engine is started,
or it may come on while
the vehicle is being driven.
This indicates that oil is not going through the engine
quickly enough to keep it lubricated. The engine
could be low on oil or could have some other oil
problem. Have it xed right away.
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
ignition is turned to RUN. 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 5-103.
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
This 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 3-16for more information.

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 “Setting the Compass” later in this section for
more information.
The buttons on the DIC trip computer are gages, trip
odometer, set/reset, options, and fuel.

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.
Average Speed:The average speed is displayed in
miles per hour (mph) or kilometers per hour (km/h). The
average speed is calculated from the various vehicle
speeds recorded since the last reset of this menu item.
