104GETTING TO KNOW YOUR INSTRUMENT PANEL
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 (P) 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 (N) and
idle the vehicle. If the temperature reading does not return
to normal, turn the engine off immediately and call for
service

This warning light will illuminate when the hood
is left open and not fully closed.
NOTE:If the vehicle is moving, there will also be a single chime.
Liftgate Open Warning Light
This warning light will illuminate when the
liftgate is open.
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.
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 200.
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 (P) or NEUTRAL (N), until the light
turns off. Once the light turns off, you may continue to
drive normally.
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.

266SERVICING AND MAINTENANCE
Conditions that would require replacement:
Rib chunking (one or more ribs has separated from belt
body)
 Rib or belt wear
 Longitudinal belt cracking (cracks between two ribs)
 Belt slips
 Groove jumping (belt does not maintain correct posi -
tion on pulley)
 Belt broken
NOTE:Identify and correct problem before new belt is installed
Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation).
Some conditions can be caused by a faulty component
such as a belt pulley. Belt pulleys should be carefully
inspected for damage and proper alignment.
Belt replacement on some models requires the use of
special tools; we recommend having your vehicle serviced
at an authorized dealer.
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–1234yf
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. It is recommended 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
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 located online, 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.
WARNING!
Do not remove the cabin air filter while the vehicle is
running, or while the ignition is in the ACC or ON/RUN
mode. With the cabin air filter removed and the blower
operating, the blower can contact hands and may
propel dirt and debris into your eyes, resulting in
personal injury.

SERVICING AND MAINTENANCE273
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a
regulated substance requiring proper disposal. Check with
your local authorities to determine the disposal rules for
your community. To prevent ingestion by animals or
children, do not store ethylene glycol-based coolant in
open containers or allow it to remain in puddles on the
ground. If ingested by a child or pet, seek emergency
assistance immediately. Clean up any ground spills
immediately.
Coolant Level
The coolant expansion bottle provides a quick visual
method for determining that the coolant level is adequate.
With the engine off and cold, the level of the coolant
(antifreeze) in the bottle should be between the “MAX”
and “MIN” lines marked on the bottle. As long as the engine operating temperature is
satisfactory, the coolant bottle need only be checked once
a month.
When additional coolant is needed to maintain the proper
level, it should be added to the coolant bottle. Do not
overfill.
See an authorized dealer for service.
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. For
the proper maintenance intervals
Úpage 260.
WARNING!
Do not open a hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over -
heated. Do not loosen or remove the cap to cool an
overheated engine. Heat causes pressure to build-up
in the cooling system. To prevent scalding or injury,
do not remove the pressure cap while the system is
hot or under pressure.
 Do not use a pressure cap other than the one speci -
fied for your vehicle. Personal injury or engine
damage may result.
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.
