Battery Volts: On vehicles with a supercharged
engine, press the SELECT button until the display
shows BATTERY VOLTS. If the voltage is normal the
display will show BATTERY
## VOLTS. If the voltage
drops below
10.5 volts for 30 seconds, the battery volts
display will show BATTERY LOW.
If the voltage is
above
16.2 volts for 30 seconds, the battery volts display
will show BATTERY HIGH.
If the display shows the
high or low message, you need to have your batterv
and/or electrical system checked.
GM Oil Life SystemTM: Press the SELECT button until
OIL LIFE appears in the display. The
OIL LIFE
NORMAL display will show an estimate of the oil’s
remaining useful life. When the oil life index is less than
IO%, an ENGINE 0iL CHANGE SOON message wiii
be displayed and the oil life display
will show OIL LIFE
CHANGE. When you have the
oil changed according
to the maintenance schedule, you will have to reset the
Oil Life System. To reset the Oil Life System, see
“When to Change Engine Oil” under
Engine Oil on
page
5- 15.
Tire Pressure Status: Press the SELECT button until
TIRE PRESSURE appears
in the display. TIRE
PRESSURE NORMAL
is displayed when the Check
Tire Pressure System believes your vehicle’s tire
pressures are normal. If a potential problem is detected,
the display will show CHECK TIRE PRESSURE and
the tire pressure status will show TIRE PRESSURE
LOW.
If you see the CHECK TIRE PRESSURE
message, you should stop
as soon as you can and
check all your tires for damage.
(If a tire is flat, see If a
Tire Goes Flat on page
5-72.) Also check the tire
pressure in all four tires as soon as you can. See
lnflation -- Tire Pressure on page 5-62 and Check Tire
Pressure System on page
5-64.
3-59

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, drive belt, cooling system and brake system.
Each of these is covered in this manual, and the
Index will help you find them quickly.
If you’re trailering,
it’s a good idea to review this information before you
start your trip.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See
Engine Overheating on
page 5-29.
Check periodically to see that all hitch nuts and bolts
are tight.
4-42

When to Change Engine Oil (Vehicles
Without the
GM Oil Life SystemTM)
If any one of these is true for you, use the short trip/city
maintenance schedule:
e
e
e
e
Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You frequently tow a trailer or use a carrier
on top
of your vehicle.
The vehicle is used for delivery service, police, tax1
or other commercial application.
Driving under these conditions causes engine oil
to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months - whichever
occurs first.
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles (1 2 500 km) or 12 months - whichever
occurs first. Driving a vehicle with a fully warmed engine
under highway conditions will cause engine oil
to
break down slower.
When to Change Engine Oil (Vehicles
With the
GM Oil Life SystemrM)
If so equipped, your vehicle has a computer system that
lets you know when to change the engine oil and
filter. This is based on engine revolutions and engine
temperature and not on mileage. Based on driving
conditions, the mileage at which an oil change will be
indicated can vary considerably. For the oil life system to
work properly, you must reset the system every time
the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. An ENGINE
OIL CHANGE SOON message
will come on. Change your oil as soon as possible
within the next two times you stop for fuel. It is possible
that,
if you are driving under the best conditions, the
oil life system may not indicate that an oil change
is necessary for over a year. However, your engine oil
and filter must be changed at least once a year and
at this time the system must be reset. It is also
important to check your oil regularly and keep it at the
proper level.
If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember
to reset the oil life system
whenever the oil is changed.

5. Fasten the

Refer to the Maintenance Schedule to determine when
to replace the air filter.

off can cause you or others to be burned. The
air cleaner not only cleans the air, it stops
flame if the engine backfires. If
it isn’t there
and the engine backfires, you could be burned.
Don’t drive with
it off, and be careful working
on the engine with the air cleaner/filter
off.
I
Notice: If the air cleanedfilter is off, a backfire can
cause a damaging engine fire.
And, dirt can
easily get into your engine, which will damage
it.
Always have the air cleaner/filter in place when
you’re driving.
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
9 In hilly or mountainous terrain.
0 When doing frequent trailer towing.

service.
If you do not use your vehicle under any of these
conditions, change the fluid and filter at
100,000 miles
(166 000 km).
See
Part A: Scheduled Maintenance Services on
page
6-4.
5-23

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid
to use. See Part D:
Recommended Fluids and Lubricants on page 6-24.
If the fluid level is low, add only enough of the proper
fluid
to bring the level into the cross-hatched area on the
dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole
to bring it to the proper level.
It doesn’t take much fluid, generally less than one
pint
(0.5 L). Don’t overfill.
Notice: We recommend you use only fluid labeled
DEXRON@-Ill, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-Ill
is
not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under “How to Check,” earlier in this
section.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL@ engine coolant. This coolant is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240
000 km), whichever occurs first, if you add
only extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see
Engine Overheating on
page
5-29.
A 50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C)
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
4. When the correct fluid level is obtained, push the
dipstick back
in all the way.

depending on your driving habits. After the system has
been calibrated, the system will alert the driver that
a tire is low, up to a maximum speed of
65 mph
(1 05 km/h).
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km).
Any time you notice unusual wear rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. See
When It Is Time
for New Tires on page 5-67 and Wheel Replacement
on page 5-69 for more information.
Tne purpose
oi reguiar rorarion is io acnieve more
uniform wear for all tires on the vehicle. The first rotation
is the most important. See “Part A: Scheduled
Maintenance Services,” in Section
6, for scheduled
rotation intervals.
