low. If you do, your engine can become so
hot that it catches re. You or others could

possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.If your vehicle has this
light, it will come on
when there is a problem
with your engine oil
pressure.
This light will come on when you turn your key to
ON or START. It goes off once you start the
engine. That is a check to be sure the light works.
If it does not come on, be sure to have it xed

If you see 99% TRANS FLUID LIFE on the display,
that means that 99% of the current transmission
uid life remains.When the transmission uid life is depleted, the
Change Trans Fluid message will appear on
the display. You should change the transmission
uid as soon as possible. Be sure to keep a written
record of the mileage and date of the uid
change so you will have it for future reference.
SeeScheduled Maintenance on page 462
andRecommended Fluids and Lubricants on
page 473for more information.
When you reset the Change Trans Fluid message

Hydraulic Clutch
It is not necessary to regularly check clutch uid

Adding uid will not correct a leak.
A uid loss in this system could indicate a
problem. Have the system inspected and repaired.
When to Check and What to Use
The hydraulic clutch
uid reservoir cap has
this symbol on it.
SeeEngine
Compartment Overview
on page 342for
reservoir location.
Refer to the Maintenance Schedule to determine
how often you should check the uid level in
your clutch master cylinder reservoir and for the
proper uid to use. SeeOwner Checks and
Services on page 469andRecommended Fluids
and Lubricants on page 473.
How to Check and Add Fluid
Make sure the uid level is at the MIN (Minimum)
line on the side of the reservoir. If it is not,
remove the cap and add the proper uid until the
level reaches the MIN line.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®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, seeEngine
Overheating on page 360.

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
If your vehicle has P245/45ZR18 96W size tires,
GM recommends rotating these tires at 3,000 mile
(4 800 km) intervals. These tires are optimized for
dry traction and handling performance. Tread life
may be 15,000 miles (24 140 km) or less for these
tires, depending on how and where you drive.
Any time you notice unusual wear, rotate your
vehicle’s tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. SeeWhen It Is Time for New Tires on
page 411andWheel Replacement on page 416for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The
rst rotation is the most important. SeeScheduled
Maintenance on page 462.

Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do
not know exactly how you will drive it. You may
drive very short distances only a few times a week.
Or you may drive long distances all the time in
very hot, dusty weather. You may use your vehicle
in making deliveries. Or you may drive it to
work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may
need more frequent checks and replacements.
So please read the following and note how
you drive. If you have any questions on how to
keep your vehicle in good condition, see your
GM Goodwrench
®dealer.
This schedule is for vehicles that:
carry passengers and cargo within
recommended limits. You will nd these limits
on the Tire and Loading Information label.
SeeLoading Your Vehicle on page 321.
