This message will be displayed if the brake uid is low.
Check the brake uid as soon as possible and have
your vehicle serviced by your GM dealer. SeeBrakes on
page 5-36for more information. Press and release
the reset stem to acknowledge the message and clear it
from the DIC display.
FUEL CAP
This message will be displayed if the vehicle’s fuel cap
is either off or loose. You should pull over and check
to see if your vehicle’s fuel cap is secure as soon
as possible. You may also see the check engine light
on the instrument panel cluster. If the check engine light
does come on when your vehicle’s fuel cap was
loose, it may take a few driving trips before the light
turns off. SeeMalfunction Indicator Lamp on page 3-35
for more information if the light still remains on. Press
and release the reset stem to acknowledge the message
and clear it from the display.
LOW FUEL
This message will be displayed if the level of fuel in the
vehicle is low. You should also check the fuel gage.
SeeFuel Gage on page 3-40for more information. You
should ll your vehicle’s fuel tank as soon as possible.
LOW TIRE
This message will be displayed if a low tire pressure is
detected in any of the vehicle’s tires. Press and
release the reset stem to acknowledge the message
and clear it from the display. The message will appear at
each ignition cycle until the tires are inated to the
correct ination pressure. SeeTires on page 5-53and
Ination - Tire Pressure on page 5-60for more
information on tires and the correct ination pressures.

This message will be displayed when the oil pressure is
low. SeeOil Pressure Light on page 3-38andEngine
Oil on page 5-13for more information.
PARK BRK (Brake)
This message will be displayed when the parking brake
is set. SeeParking Brake on page 2-27andBrake
System Warning Light on page 3-32for more
information. The message will clear from the display
after the parking brake is released.

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.
SeeEngine 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.
5-13

Wait at least 30 minutes before checking the
transmission uid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially in hot weather.
While pulling a trailer.
To get the right reading, the uid should be at normal
operating temperature, which is 180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it is colder than 50°F (10°C), drive the vehicle
in THIRD (3) until the engine temperature gage
moves and then remains steady for 10 minutes.
A cold uid check can be made after the vehicle has
been sitting for eight hours or more with the engine off,
but this is used only as a reference. Let the engine
run at idle for ve minutes if outside temperatures are
50°F (10°C) or more. If it is colder than 50°F (10°C), you
may have to idle the engine longer. Should the uid
level be low during this cold check, you must check the
uid hot before adding uid. Checking the uid hot
will give you a more accurate reading of the uid level.
Checking the Fluid Level
Prepare your vehicle as follows:
1. Park your vehicle on a level place. Keep the engine
running.
2. With the parking brake applied, place the shift lever
in PARK (P).
3. With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position
the shift lever in PARK (P).
4. Let the engine run at idle for three minutes or more.
Then, without shutting off the engine, follow these steps:
1. Flip the handle up and then pull out the dipstick
and wipe it with a clean rag or paper towel.
The automatic
transmission dipstick
handle with this symbol on
it is located in the engine
compartment on the
passenger’s side of
the vehicle.
SeeEngine Compartment Overview on page 5-12
for more information on location.

Brakes
Brake Fluid
Your brake master cylinder
reservoir is lled with
DOT-3 brake uid.
SeeEngine Compartment
Overview on page 5-12
for 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 system. If it is, you should have
your brake system xed, since a leak means that
sooner or later your brakes will not work well, or will not
work at all.So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you add
uid when your linings are worn, then you will have
too much uid when you get new brake linings.
You should add or remove brake uid, as necessary,
only when work is done on the brake 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
hydraulic system. See “Checking Brake Fluid”
in this section.
Refer to the Maintenance Schedule to determine when
to check your brake uid. SeeScheduled Maintenance
on page 6-4.
5-36

Checking Brake Fluid
You can check the brake uid without taking off the cap.
Look at the brake uid reservoir. The uid level should
be above MIN. If it is not, have your brake system
checked to see if there is a leak.
After work is done on the brake hydraulic system,
make sure the level is above the MIN but not over the
MAX mark.
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
system, your brakes 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
system parts. For example, just a few drops of
mineral-based oil, such as engine oil, in your
brake system can damage brake 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.
SeeAppearance Care on page 5-85.
5-37

Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. SeeEngine
Coolant on page 5-24for further details.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in the windshield
washer tank and add the proper uid if necessary.
At Least Once a Month
Tire Ination Check
Visually inspect your vehicle’s tires and make sure they
are inated to the correct pressures. Do not forget to
check the spare tire. SeeTires on page 5-53for further
details. Check to make sure the spare tire is stored
securely. SeeChanging a Flat Tire on page 5-73.
Tire Wear Inspection
Tire rotation may be required for high mileage highway
drivers prior to the Engine Oil Life System service
notication. Check the tires for wear and, if necessary,
rotate the tires. SeeTire Inspection and Rotation on
page 5-64.
At Least Once a Year
Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. SeeParking Brake on page 2-27.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
