1998 PONTIAC GRAND PRIX warning light

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.

Functions
CHANGE OIL SOON: This light will appear when
the system predicts that the oil’s remaining useful life is \
almost up. The system predicts remaining oil life using
inputs from length of drives, coolant temperature, engine rpm and vehicle speed. It alerts you to change
the oil on a schedule consistent with your vehicle’s driving conditions.
After changing the oil, the system must be reset. With
the ignition key in the ON position but the engine
off,
fully push and release the accelerator pedal slowly three
times within five seconds. If the CHANGE
OIL SOON
light flashes, the system is resetting. Turn the ignition
key to the OFF position, then start the vehicle. If the
CHANGE OIL SOON light comes back on, the oil life
monitor has not reset. Repeat the procedure.
LOW WASHER FLUID: This light will come on when
your ignition is on and the fluid container is low.
TRUNK A JAR: This light alerts you that your trunk is
not fully closed.
DOOR AJAR: If one of your doors is left ajar, a light
will appear next to that door on the vehcle outline.
TRAC SWITCH: If your vehicle has the Trac System,
you will have
a disable switch on the far right side of
your Driver Information Center. Your Trac System is automatically activated when you turn the ignition on.
This switch will activate/deactivate the Trac System. If
you need to disable the system, such as when you are
stuck and are rocking your vehicle back and forth, push
this switch. See “Stuck: In Sand, Mud, Ice or Snow” in
the Index.
TRAC OFF: This light lets you know that your Trac
System has been disabled and will not limit wheel spin. See “Enhanced Traction System Warning Light”
or
“Low Traction Light” in the Index.
LOW TRAC: This light will come on when your Trac
System is limiting wheel spin. See “Trac System” or
“Low Traction Light”
in the Index.
2-77

TCS OFF: This light lets you know that your Traction
Control System has been disabled and will not limit
wheel spin. See “Traction Control System Warning
Light” or “Low Traction Light” in the Index.
LOW TRAC: This light will come on when your
Traction Control System is limiting wheel spin. See “Traction Control System” or “Low Traction Light” in
the Index.
Head-Up Display (If Equipped)
If you have the Head-Up
Display (HUD), you can see
the speedometer reading (in
English or metric units) and
a brief display of the current
radio station or CD track,
displayed
“through” the
windshield.
The
HUD also shows these lights when they are lit on
the instrument panel:
0 Turn Signal Indicators
0 High-Beam Indicator Symbol
Low Fuel Symbol
The HUD will display the “Check Gage” when the
following are lit on the instrument panel:
0 Oil Warning Symbol
0 Coolant Temperature Symbol
0 Charging System Symbol
When you sit straight in your seat, the HUD image will appear straight ahead near the front bumper.
When the ignition key is turned to
RUN, the HUD
image
will come on. Then the Head-Up Display will
operate normally.
I NOTICE: I
Although the HUD image appears to be near the
front
of the vehicle, do not use it as a parking aid.
The
HUD was not designed for that purpose. If
you try to use it that way, such as in a parking
lot, you may misjudge distance and run
into something.
2-81

Avoid needless heavy braking. Some people drive in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you do
a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you’re driving, brake
normally but don’t pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer
to stop and the brake pedal
will be harder
to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when you begin
to drive
away, your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise
while
this test is going on, and you may even notice that your
brake pedal moves or pulses a little. This is normal.
If there’s a problem with the
anti-lock brake system,
this
warning light will stay on.
See “Anti-Lock Brake
System Warning Light” in
the Index.

Remember: Anti-lock doesn’t change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle
in
front of you, you won’t have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to
stop, even though you have
anti-lock brakes.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work for you. You may feel a
slight brake pedal pulsation or notice some noise, but
this is normal.
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
this light will come on.
Traction Control System (With 3800
Supercharged Engine)
Your vehicle has a traction control system that limits wheel
spin.
This is especially useful in slippery road conditions.
The system operates only if it senses that one or both of
the front wheels are spinning or beginning to lose traction.
When
this happens, the system works the front brakes and
reduces engine power to limit wheel spin.
LOW
TRAC
This light will come on
when your traction control system is limiting wheel
spin. See “Traction Control
System Warning Light” in
the index.
You may
feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin,
the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. (See “Cruise Control” in the Index.)

This light should come on briefly when you start

you are
driving, there’s a problem with your traction
control system.
TCS
OFF
the engine. If it stays on or
See “Traction Control System Warning Light” in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on
whenever you start your vehicle.
To limit wheel spin,
especially in slippery road conditions, you should
always leave the system on. But you can
turn the
traction control system
off if you ever need to. (You
should
turn the system off if your vehicle ever gets stuck
in sand, mud, ice or snow. See “Rocking Your Vehicle”
in the Index.)
To turn the system off,
press the TCS button on
the far right end of the
trip computer.
The traction control system warning light will come
on and stay on. If the system is limiting wheel spin
when you press the button, the warning light will come
on -- and the system will shut-off instantly. It will wait
until there’s no longer
a current need to limit
wheel spin.
You can
turn the system back on at any time by pressing
the button again. The traction control system warning
light should go
off.
4-10

Enhanced Traction System
(3100 or 3800 Engine)
Your vehicle may have an Enhanced Traction System (ETS) that limits wheel spin. This is especially useful
in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels
are spinning
or beginning to lose traction. When
this happens, the
system reduces engine power and may
also upshift the
transaxle
to limit wheel spin.
LOW
TRAC
This light will come on when your Enhanced
Traction System is limiting wheel spin. See “Enhanced
Traction
System Warning
Light
” in the index.
You may feel or hear the system working, but this
is normal.
The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle
only as high as the shift lever position you’ve
chosen,
so you should use the lower gears only when
necessary. See “Automatic Transaxle” in
the Index.

This warning light will
come
on to let you know if
there’s a problem with the TRAC
OFF
system.
See “Enhanced Traction System Warning Light” in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can
turn the system off if
you ever need to. (You should turn the system off if your
vehicle ever gets stuck in sand, mud, ice or snow. See
“Rocking Your Vehicle” in the Index.)
