1998 PONTIAC GRAND PRIX oil reset

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.

Control Buttons
The trip computer has three buttons that control its functions.
ENGMET: Press this button to change the display from
English to metric units or metric to English.
RESET Press this button for two seconds to reset the

MODE: Press this button to change the mode
being displayed.
Functions
FUEL USED: Shows the total amount of fuel used
since you last reset this mode. The amount can be
displayed in gallons
or liters.
AVG ECON: Shows your average fuel economy since
you last reset this mode.
OIL LIFE: Shows a percentage of the oil’s remaining
useful life. The system predicts remaining oil life using
inputs from length of drives, coolant temperature,
engine rpm and vehicle speed. Each time
you get an oil
change, be sure to reset this function
so that it will give
you an accurate percentage.
To reset the Oil Life Indicator after the oil has been
changed, press the
MODE button until the light appears lit next
to
OIL LIFE. Press and hold the RESET button
for
three seconds. The oil life percentage should change
to
100%.
RANGE: Shows how much farther you can travel with
the fuel you have before refueling.
LOW WASHER FLUID: This light will come on when
your ignition
is on and the fluid container is low.
DOOR AJAR: If one of your doors is left ajar, a light
will appear next to that
door on the vehicle outline.
BOOST GAGE: If you have the supercharged engine,
this gage will show the amount of boost your engine
is receiving.
TRUNK AJAR: If your trunk is not fully closed or
open, a light will outline the trunk
area on your
vehicle outline.
TCS SWITCH: If your vehicle has the Traction Control
System, you will have
a disable switch on the far right
side of your Trip Computer. Your Traction Control
System
is automatically activated when you turn the
ignition on. This switch will activate/deactivate the
Traction Control 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.

Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready to advise
if you think something should be added.
How to Reset the CHANGE OIL SOON Light
When to Change Engine Oil
Your vehicle has an Oil Life Monitor. This feature
will let you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come
on
before 3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won’t detect dust in the oil. So, if you
drive in a dusty area, be sure to change your oil every
3,000 miles (5 000 km) or sooner. Remember to reset
the Oil Life Monitor when the oil has been changed. For
more information, see “CHANGE
OIL SOON Light” in
the Index.
To reset your CHANGE OIL SOON light after an oil
change, turn
the key to ON, without the engine running
and pump the accelerator three times within five seconds.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly
throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and
disposal
of oil products.)
Used oil can
be a real threat to the environment. If you
change your own oil, be sure to drain
all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166
OOO km) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at
150,000 miles (240 000 km) should be performed at
the same interval after 150,000 miles
(240 000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
? The US. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform
this maintenance item will not nullify
the emission warranty or limit recall liability prior
to the
completion
of the vehicle’s useful life. We, however,
urge that
all recommended maintenance services be
performed at the indicated intervals and the maintenance be recorded.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show you when to change the engine oil
and filter
-- usually between 3,000 miles (5 OOO km) and
7,500 miles (12 500 km) since your last oil change.
Under severe conditions, the indicator may come
on
before 3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 km) or 12 months
without
an oil and filter change.
The system won’t detect dust
in the oil. So if you drive
in
a dusty area, be sure to change your oil and filter
every 3,000 miles (5 000 km) or sooner if the CHANGE
OIL SOON light comes on. Remember to reset the
Oil Life Monitor when the oil has been changed. For
more information, see “CHANGE
OIL SOON light”
in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspections”
