70GETTING TO KNOW YOUR INSTRUMENT PANEL
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
Úpage 216.
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.
Seat Belt Reminder Warning Light
This warning light indicates when the driver or
passenger seat belt is unbuckled. When the
ignition is first placed in the ON/RUN or ACC/
ON/RUN position and if the driver’s seat belt is
unbuckled, a chime will sound and the light will turn on.
When driving, if the driver or front passenger seat belt
remains unbuckled, the Seat Belt Reminder Light will flash
or remain on continuously and a chime will sound
Úpage 177.
Transmission Temperature Warning Light
This warning light will illuminate to warn of a
high transmission fluid temperature. This may
occur with strenuous usage such as trailer
towing. If this light turns on, stop the vehicle
and run the engine at idle or slightly faster, with the
transmission in PARK or NEUTRAL, until the light turns off.
Once the light turns off, you may continue to drive
normally.
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.
Vehicle Security Warning Light —
If Equipped
This light will flash at a fast rate for
approximately 15 seconds when the vehicle
security system is arming, and then will flash
slowly until the vehicle is disarmed.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is illuminated
you could cause the fluid to boil over, come in contact
with hot engine or exhaust components and cause a
fire.
CAUTION!
Continuous driving with the Transmission Temperature
Warning Light illuminated will eventually cause severe
transmission damage or transmission failure.

230SERVICING AND MAINTENANCE
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
Refrigerant Recovery And Recycling
R-134a — If Equipped
R-134a Air Conditioning Refrigerant is a Hydrofluo -
rocarbon (HFC) that is an ozone-friendly substance. The
manufacturer recommends that air conditioning service
be performed by an authorized dealer or other service
facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.
Refrigerant Recovery And Recycling
R-1234yf — If Equipped
R-1234yf Air Conditioning Refrigerant is a Hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance with
a low global-warming potential. The manufacturer
recommends that air conditioning service be performed by
an authorized dealer using recovery and recycling
equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil, and refrigerants.
Cabin Air Filter
The filter is located in the fresh air inlet under the hood,
behind a removable panel in the cowl on the passenger
side of the vehicle, next to the windshield wipers. When
installing a new filter, ensure its proper orientation.
1. Remove the access door in the cowl screen by
pressing the retaining clips.

WARNING!
Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi -
tioning 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
information.
 The air conditioning system contains refrigerant
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.

236SERVICING AND MAINTENANCE
(Continued)
The radiator normally remains completely full, so there is
no need to remove the radiator/coolant pressure cap
unless checking for engine coolant freeze point or
replacing coolant. Advise your service attendant of this. As
long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant is needed to maintain the
proper level, only OAT coolant that meets the
requirements of manufacturer Material Standard
MS.90032 should be added to the coolant bottle.
Do not overfill.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilometers
of operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulating
on the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to enter
the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.

Do not overfill the coolant expansion bottle.
 Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant needs
to be added, the contents of the coolant expansion
bottle must also be protected against freezing. 
If frequent engine coolant additions are required, the
cooling system should be pressure tested for leaks.
 Maintain engine coolant concentration at a minimum
of 50% OAT coolant (conforming to MS.90032) and
distilled water for proper corrosion protection of your
engine which contains aluminum components.
 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 necessary, 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
Úpage 221.
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.
For further information
Úpage 271.
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 271. 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.
