Brake System Warning Light
Your vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
This light should come on when you start the engine. If
it does not come on then, have it ®xed so it will be
ready to warn you if there is a problem.
If this warning light stays on after you start the engine,
the parking brake may still be set or there could be
a brake problem. Refer to
Parking Brake on page 2-26to see if it is set. If the parking brake is not set, have
your brake system inspected right away.If the light comes on while you are driving and you have
a LOW BRAKE FLUID message showing on the DIC,
pull off the road and stop carefully. You may notice that
the pedal is harder to push. Or, the pedal may go
closer to the ¯oor. It may take longer to stop. If the light
is still on, have the vehicle towed for service. See
Towing Your Vehicle on page 4-32.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed for
service. United States

ENGINE PROTECTION REDUCE ENGINE RPM:If this
message appears, the control system has determined
that continued operation at the existing engine
speed may lead to engine overheating. Therefore, you
should lower the engine speed by upshifting the
transmission or drive at a lower speed.
HEADLAMPS SUGGESTED:If it is dark enough
outside and the headlamps and Twilight Sentinel
ž
controls are off, this message will display on the DIC.
This message informs the driver that turning on the
exterior lamps is recommended even though the DRL
are still illuminated. It has become dark enough outside
to require the headlamps and/or other exterior lamps.
This message will also appear if the optional
RainsenseŸ wiping feature is on and the Twilight
Sentinel
žis off.
HIGH TRANS TEMP:This message indicates that the
transaxle ¯uid in your vehicle is too hot. Stop and
allow your vehicle to idle until it cools down or until this
message is removed.
HIGH VOLTAGE:This message shows that the
electrical charging system is overcharging. To avoid
being stranded, have the electrical system checked by
your dealership. You can reduce the charging
overload by using the accessories. Turn on the lamps
and radio, set the climate control on AUTO and the
fan speed on HI, and turn the rear window defogger on.You can monitor battery voltage on the DIC by pressing
the INFO button. The normal range is 11.5 to 15.5 volts
when the engine is running.
HOT ENGINE±A/C OFF:This message displays when
the engine coolant becomes hotter than the normal
operating temperature. To avoid added strain on a hot
engine, the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation will automatically resume. You
can continue to drive your vehicle. If this message
continues to appear, have the system repaired as soon
as possible to avoid compressor damage.
ICE POSSIBLE:This message appears when the
outside air temperature is cold enough to create icy road
conditions.
LEFT DOOR AJAR:This message will display anytime
the vehicle engine is running, the transmission is not
in PARK (P) and the driver's door is open or ajar.
A chime will sound when the vehicle's speed is greater
than 3 mph (4.8 km/h).
LOW BRAKE FLUID:This message will display if the
vehicle is running to inform the driver that the brake
¯uid level is low. Have the brake system serviced by a
technician as soon as possible. See ªBrake Fluidº
under
Brakes on page 5-35.

Engine Oil
If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center appears, it
means you need to check your engine oil level right
away. For more information, see ªLOW OIL LEVELº and
ªLOW OIL PRESSUREº under
DIC Warnings and
Messages on page 3-57.You should check your engine oil level regularly; this is
an added reminder.
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.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil
dipstick might not show the actual level.
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.

Brakes
Brake Fluid
Your brake master cylinder 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 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 ªtop offº 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 ªChecking Brake Fluidº
in this section.
Refer to the Maintenance Schedule to determine when
to check your brake ¯uid. See
Scheduled Maintenance
on page 6-4.
5-35

Checking Brake Fluid
You can check the brake ¯uid without taking off the cap.
Just look at the brake ¯uid reservoir. The ¯uid level
should be above the MIN mark on the reservoir. 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 between the MIN and MAX marks.
What to Add
When you do need brake ¯uid, use only DOT-3 brake
¯uid. Refer toRecommended Fluids and Lubricants
on page 6-11. Use new brake ¯uid from a sealed
container only.
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. See
Appearance
Care on page 5-75.

Recommended Fluids and
Lubricants
Fluids and lubricants identi®ed below by name, part
number or speci®cation may be obtained from your
dealer.
Usage Fluid/Lubricant
Engine OilThe engine requires a special
engine oil meeting GM Standard
GM4718M. Oils meeting this
standard may be identi®ed as
synthetic, and should also be
identi®ed with the American
Petroleum Institute Certi®ed for
Gasoline Engines starburst symbol.
However, not all synthetic API oils
with the starburst symbol will meet
this GM standard. You should look
for and use only an oil that meets
GM Standard GM4718M. GM
Goodwrench oil meets all the
requirements for your vehicle. For
the proper viscosity, see
