1998 PONTIAC GRAND PRIX oil level

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.
Automatic Transaxle Operation
I ‘%
6
10
Your automatic transaxle may have a shift lever on the
steering column or on the console between the seats.
Maximum engine speed is limited when you’re in
PARK (P) or NEUTRAL (N), to protect driveline
components from improper operation. There are several different positions
for your shift lever.
PARK
(P): This locks your front wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
It is dangerous to get out of your vehicle if the
shift lever
is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine
is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to PARK
(P).
See “Shifting Into PARK (P)” in the Index. If
you’re pulling a trailer, see “Towing a Trailer” in
the Index.

A CAUTION:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your
oil as soon as possible and have your
vehicle serviced.
I NOTICE:
Damage to your engine from neglected oil problems
can be costly and is not covered by
your warranty.
PERF
SHIFT
This light comes on when
you press the performance
shift button (located on the
console shift) to indicate
that your vehicle is in
performance shifting mode.
See “Performance Shifting” in
the Index.
Low Oil Level Light
LOW OIL
LEVEL
Your engine is equipped
with
an oil level monitoring
system. When the ignition
key is turned
to ON, the
LOW OIL LEVEL light
will briefly flash.
If the light does not flash, have it fixed so it will be
ready to
warn you if there’s a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. (See “Engine Oil” in the Index.)
2-72

The oil level monitoring system only checks oil level during the brief period between key on and engine
crank. It
does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned
off for a
considerable period of time, allowing the oil normally in
circulation to drain back into the oil pan.
Engine Coolant Temperature Light
TEMP
This light tells you that your
engine coolant has
overheated or your radiator
cooling fan
is not working.
If you have been operating your
vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.
Engine Coolant Temperature Gage
You have a gage that shows
the engine coolant
temperature. If the gage
pointer moves into
the red
area, your engine is too hot!
That reading means the sarne thing as the warning light.
It means
that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull
off the road, stop your
vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,”
this manual shows what to
do. See “Engine Overheating” in the Index.

The exit speed is usually posted.
Reduce your speed according
to your speedometer, not
to your sense
of motion. After driving for any distance
at higher speeds, you may tend to think you are going
slower than you actually
are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must
start when you’re not fresh -- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced
and maintained, it’s ready to go. If it needs
service, have it done before starting out.
Of course,
you’ll find experienced
and able service experts in
Pontiac dealerships all across North America. They’ll be
ready and willing to help if you need it. Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir
full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along
your route? Should you delay your trip a short
time to avoid
a major storm system?
Maps: Do you have up-to-date maps?

’ A CAUTION:
An electric engine cooling fan under the hood can
start up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away
from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it
cools down.
The coolant level should be at or above the COLD mark
on the overflow hose
in the coolant recovery tank. To
check the coolant level, remove the cap on the coolant
recovery tank. Check to make sure that the coolant level
is up to the COLD fill level on the hose attached to
the cap.
If it isn’t,
you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else in
the cooling system.
5-19

I A CAUTION: I
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause
an engine fire, and you could be burned.
Get any leak fined before you drive the vehicle.
NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine
on, check to
see if the electric engine cooling fans are running. If the
engine is overheating,
both fans should be running. If
they aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
COLD mark, add a 50/50 mixture of clean
wuter (preferably distilled) and DEX-COOL@ engine
coolant at the coolant recovery tank. (See “Engine
Coolant”
in the Index for more information.)
Adding only
plain water to your cooling system
can
be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture
will. Your vehicle’s coolant
warning system
is set for the proper coolant
mixture. With plain
water or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could
be burned.
Use
a 50/50 mixture of clean water and
DEX-COOL@ coolant.

Before closing the hood, be sure all the filler caps are
on properly. Then just pull the hood down and close
it fiiy.
3800 Supercharged Engine
(If Equipped)
Your vehicle may have a 3800 Supercharged engine.
The supercharger is a device which is designed to pump
more air into the engine than it would normally use.
This air, mixed with fuel, creates increased engine
power. Since the supercharger is a pump and is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
The Powertrain Control Module (PCM) works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling and light throttle cruising, the excess air that the supercharger is pumping is routed through a bypass.
All of these controls working together provide high
performance character and fuel efficiency
in the
3800 Supercharged engine.
Engine Oil
LOW OIL
LEVEL
If the LOW OIL LEVEL
light on the instrument
panel comes on, it means
you need to check
your
engine oil level right away.
For more information, see “Low
Oil Level Light” in the
Index. You should check your engine oil level regularly;
this is an added reminder.
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick
handle is the yellow loop
near the front of the engine.
