GETTING TO KNOW YOUR INSTRUMENT PANEL75
Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to
indicate a problem with the ETC system.
If a problem is detected while the vehicle
is running, the light will either stay on or
flash depending on the nature of the problem.
Cycle the ignition when the vehicle is safely and
completely stopped and the transmission is placed
in the PARK position. The light should turn off. If
the light remains on with the vehicle running, your
vehicle will usually be drivable; however, see an
authorized dealer for service as soon as possible.
NOTE:This light may turn on if the accelerator and brake
pedals are pressed at the same time.
If the light continues to flash when the vehicle is
running, immediate service is required and you
may experience reduced performance, an
elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come on
when the ignition is placed in the ON/RUN or ACC/
ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting,
have the system checked by an authorized dealer.
Engine Coolant Temperature Warning
Light
This warning light warns of an
overheated engine condition. If the
engine coolant temperature is too high,
this indicator will illuminate and a single
chime will sound. If the temperature reaches the
upper limit, a continuous chime will sound for four
minutes or until the engine is able to cool,
whichever comes first.
If the light turns on while driving, safely pull over
and stop the vehicle. If the Air Conditioning (A/C)
system is on, turn it off. Also, shift the transmission
into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal,
turn the engine off immediately and call for service
Ú page 248.
Trunk Open Warning Light
This indicator will illuminate when the
trunk is open and not fully closed.
NOTE:If the vehicle is moving, there will also be a single
chime.
Oil Pressure Warning Light
This warning light will illuminate to
indicate low engine oil pressure. If the
light turns on while driving, stop the
vehicle, shut off the engine as soon as
possible, and contact an authorized dealer. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not indicate how much oil
is in the engine. The engine oil level must be
checked under the hood.
Oil Temperature Warning Light
This warning light will illuminate to
indicate the engine oil temperature is
high. If the light turns on while driving,
stop the vehicle and shut off the engine
as soon as possible. Wait for oil temperature to
return to normal levels.

WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty
Information Book, for further warranty infor -
mation.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an
experienced technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.

22_LA_OM_EN_USC_t.book Page 266

274SERVICING AND MAINTENANCE
(Continued)
Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning, keep
the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever neces-
sary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas mileage,
and increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú page 255.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the Brake System Warning Light
indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However,
low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended
by the manufacturer, and has been kept in a tightly
closed container to avoid contamination from
foreign matter or moisture Ú page 316.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in
abnormally high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.
WARNING!
Use only manufacturer's recommended brake
fluid Úpage 316. Using the wrong type of
brake fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory installed
hydraulic master cylinder reservoir.
To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep
the master cylinder reservoir cap secured at
all times. Brake fluid in a open container
absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This
could result in a collision.
Overfilling the brake fluid reservoir can result
in spilling brake fluid on hot engine parts,
causing the brake fluid to catch fire. Brake
fluid can also damage painted and vinyl
surfaces, care should be taken to avoid its
contact with these surfaces.

SERVICING AND MAINTENANCE307
TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well on
the government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These grades
represent the tire's ability to stop on wet
pavement, as measured under
controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
TEMPERATURE GRADES
The Temperature grades are A (the
highest), B, and C, representing the tire's
resistance to the generation of heat and
its ability to dissipate heat, when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance, which all
passenger vehicle tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A
represent higher levels of performance
on the laboratory test wheel, than the
minimum required by law.VEHICLE STORAGE
If you are leaving your vehicle dormant for more
than 3 weeks, you may want to take these steps to
protect your battery.
Disconnect the negative cable from the battery.
Anytime you store your vehicle, or keep it out of
service (e.g., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
WARNING!
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
WARNING!
The temperature grade for this tire is
established for a tire that is properly inflated and
not overloaded. Excessive speed, underinflation,
or excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
