pressure light, this light
comes on briey when the
engine is started and
provides information about
tire pressures and the
Tire Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is signicantly
underinated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDIC
Warnings and Messages on page 3-54for more

page 5-73for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of

CHECK GAS CAP
This message displays if the fuel cap has not been fully
tightened. Check the fuel cap to make sure that it is
on properly. Once tightened, it takes at least one
overnight park to reset or clear this message. If both the
CHECK GAS CAP message and the malfunction

two chimes sound if the oil level in the vehicle is low.
Once the vehicle senses a change in the engine
oil level, the light remains off.If this message appears after starting the engine, the
engine oil level may be too low. You may need to
add oil. SeeEngine Overheating on page 5-39.
To acknowledge the message, press the RESET button.
The message reappears every 10 minutes until this
condition changes.

Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines might be available in
your area. We recommend that you use these gasolines,
if they comply with the specications described earlier.
However, E85 (85% ethanol) and other fuels containing
more than 10% ethanol must not be used in vehicles that
were not designed for those fuels.
Notice:This vehicle was not designed for fuel
that contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under the
vehicle warranty.
Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance of
the emission control system could be affected. The
malfunction indicator lamp might turn on. If this occurs,
return to your dealer/retailer for service.Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel might be hard
to nd. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel would not be covered by
the vehicle warranty.
To check the fuel availability, ask an auto club, or
contact a major oil company that does business in
the country where you will be driving.

5. Replace the pressure cap. Be sure the pressure
cap is hand-tight and fully seated.
Check the level in the surge tank when the system
has cooled down. If the coolant is not at the proper
level, repeat Steps 1 through 4, then reinstall the
pressure cap. If the coolant is not at the proper
level when the system cools down again, see your
dealer/retailer.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
There is an engine coolant temperature gage on
the instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-41. The vehicle may
also display a COOLANT OVER TEMPERATURE
message on the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 3-54
for more information.You may decide not to lift the hood but to get service
help right away. SeeRoadside Assistance Program
on page 7-7.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fan is running.
If the engine is overheating, the fan should be running.
If it is not, do not continue to run the engine and have the
vehicle serviced.
Notice:Engine damage from running your engine
without coolant is not covered by your warranty.
SeeOverheated Engine Protection Operating Mode
on page 5-41for information on driving to a safe
place in an emergency.
Notice:If the engine catches re while driving
with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the
vehicle warranty. SeeOverheated Engine Protection
Operating Mode on page 5-41for information on
driving to a safe place in an emergency.

Brake Wear (Except ZR1)
This vehicle has 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 can come and go or be heard
all the time the vehicle is moving, except when applying
the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to an
accident. When the brake wear warning sound is
heard, have the vehicle serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates can cause a brake
squeal when the brakes are rst applied or lightly applied.
This does not mean something is wrong with the brakes.
Brake linings should always be replaced as complete
axle sets.
Brake Wear (ZR1 Only)
The ZR1 model does not have built-in brake pad wear
indicators and periodic visual inspection of the brake pads
is required to determine when to replace the brake pads.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Make sure that the brakes have been given
sufficient time to cool and then set the park brake.
Brake pads can be visually inspected through the
wheel by inspecting the outer brake pads at each
wheel.
Brake pads should be replaced when worn to
two mm of pad thickness. New pads are 10 mm thick.
In addition, brake pad inspection is required any time
the tires are removed.Front
