2004 PONTIAC GRAND PRIX open hood

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. See
Engine Compartment Overview
on page 5-12for 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
won't 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 to keep it away
from moving engine parts. If you don't, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave the
interior, trunk or underhood lamps on. If you leave any of
these lamps on while the ignition is in LOCK or OFF,
they will automatically turn off after 10 minutes. The
lamps won't come back on again until you do one of the
following:
·Turn the ignition to RUN or ACCESSORY.
·Turn the interior lamps control completely to the
right, then back slightly to the left.
·Open (or close and reopen) a door that is closed.
If the vehicle has less than 15 miles (25 km) on
the odometer, the battery saver will turn off the lamps
after only three minutes.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright or too high in
your ®eld of view, it may take you more time
to see things you need to see when it's dark
outside. Be sure to keep the HUD image dim
and placed low in your ®eld of view.
If your vehicle is equipped with the Head-Up Display
(HUD), you can see the speedometer reading (in English
or metric units), transaxle positions, compass direction,
outside air temperature, and a brief display of the
current radio station or CD track, displayed ªthroughº
the windshield.
English or metric units selection is done through the
trip computer in the Driver Information Center (DIC).

Overheated Engine Protection
Operating Mode
This emergency operating mode allows your vehicle to
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an overheat
protection mode which alternates ®ring groups of
cylinders helps prevent engine damage. In this mode,
you will notice a signi®cant loss in power and engine
performance. The engine coolant temperature gage will
indicate an overheat condition exists. Driving extended
miles (km) and/or towing a trailer in the overheat
protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair the
cause of coolant loss, change the oil and reset the oil
life system. See ªEngine Oilº in the Index.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood.
Stay away from the engine if you see or hear
steam coming from it. Just turn it off and get
everyone away from the vehicle until it cools
CAUTION: (Continued)
