OIL LIFE
Press the information button until OIL LIFE is displayed.
The engine oil life system shows an estimate of the
oil’s remaining useful life. It will show 100% when the
system is reset after an oil change. It will alert you
to change your oil on a schedule consistent with your
driving conditions.
In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in
the Maintenance Schedule in this manual. SeeEngine
Oil on page 5-15andScheduled Maintenance on
page 6-4.
Always reset the engine oil life system after an oil
change. See “How to Reset the Engine Oil Life System”
underEngine Oil Life System on page 5-20and
“OIL–LIFE RESET” underDIC Vehicle Personalization
on page 3-43.
COOLANT
Press the information button until COOLANT is
displayed. This mode shows the temperature of the
engine coolant in either degrees Fahrenheit (°F)
or degrees Celsius (°C).
DIC Warnings and Messages
These messages will appear if there is a problem
detected in one of your vehicle’s systems.
Any message will clear when the vehicle’s condition is
no longer present. The warning message will come back
on the next time the vehicle is turned off and back on
if the condition is still present. With most messages,
a warning chime will sound when the message is
displayed. You can also acknowledge and clear some
warning messages from the DIC display by pressing
either the reset or information buttons. Your vehicle may
have other warning messages.
AUTO (Automatic) LIGHTS OFF
This message is displayed if the automatic headlamp
system is disabled with the headlamp switch.
AUTO (Automatic) LIGHTS ON
This message is displayed if the automatic headlamp
system is enabled with the headlamp switch.
BRAKE FLUID
This message will display if the ignition is on to inform
the driver that the brake uid level is low. Have the
brake system serviced by your GM dealer as soon as
possible.

Checking Engine Oil
It is 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 a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
5-15

Automatic Transaxle Fluid
It is not necessary to check the transaxle uid level.
A transaxle uid leak is the only reason for uid loss.
If a leak occurs, take your vehicle to the dealership
service department and have it repaired as soon
as possible.
Change the uid and lter at the intervals listed in
Additional Required Services on page 6-6, and be
sure to use the transaxle uid listed inRecommended
Fluids and Lubricants on page 6-12.
Notice:Use of the incorrect automatic transaxle
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transaxle uid listed in
Recommended Fluids and Lubricants on page 6-12.
Manual Transaxle Fluid
It is not necessary to check the transaxle uid level.
A transaxle uid leak is the only reason for uid loss.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible. SeeRecommended Fluids and Lubricants on
page 6-12for the proper uid to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives uid from the brake master
cylinder reservoir.
SeeBrakes on page 5-38for more information.
5-23

Brakes
Brake Fluid
Your brake master cylinder
and, on manual transaxle
vehicles, the hydraulic
clutch use the same
reservoir. The reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview on
page 5-12for the location
of the reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down. The rst is that the brake
uid goes down to an acceptable level during normal
brake lining wear. When new linings are put in, the uid
level goes back up. The other reason is that uid is
leaking out of the brake and/or clutch hydraulic system.
If it is, you should have your brake and/or clutch system
xed, since a leak means that sooner or later your brakes
and/or clutch will not work well, or will not work at all.So, it is not a good idea to top off your brake/clutch uid.
Adding uid will not correct a leak. If you add uid when
your brake linings are worn, then you will have too much
uid when you get new brake linings. You should add or
remove uid, as necessary, only when work is done on
the brake/clutch hydraulic system.
{CAUTION:
If you have too much brake uid, it can spill on
the engine. The uid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
uid only when work is done on the brake
and/or clutch hydraulic system.
When your brake uid falls to a low level, your brake
warning light will come on. SeeBrake System Warning
Light on page 3-29.
5-38

What to Add
When you do need brake uid, use only DOT-3 brake
uid. Use new brake uid from a sealed container
only. SeeRecommended Fluids and Lubricants on
page 6-12.
Always clean the brake uid reservoir cap and the area
around the cap before removing it. This will help
keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in your
brake/clutch system, your brakes/clutch may
not work well, or they may not even work at
all. This could cause a crash. Always use the
proper brake uid.
Notice:
Using the wrong uid can badly damage brake/
clutch system parts. For example, just a few
drops of mineral-based oil, such as engine oil, in
your brake/clutch hydraulic system can damage
brake/clutch system parts so badly that they will
have to be replaced. Do not let someone put in
the wrong kind of uid.
If you spill brake uid on your vehicle’s painted
surfaces, the paint nish can be damaged.
Be careful not to spill brake uid on your vehicle.
If you do, wash it off immediately. SeeWashing
Your Vehicle on page 5-92.
Brake Wear
Your vehicle has front disc brakes and may have rear
drum brakes or rear disc brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and go or be heard all the time your vehicle is moving,
except when you are pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that soon
your brakes will not work well. That could lead
to an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
