INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Seat Belt Reminder Light
When the ignition switch is first turned to the
ON/RUN position, this light will turn on for four
to eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a chime will
sound. After the bulb check or when driving, if the driver
or front passenger seat belt remains unbuckled, the Seat
Belt Indicator Light will flash or remain on continuously.
Refer to “Occupant Restraints” in “Things To Know
Before Starting Your Vehicle” for further information.3. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.

Certain conditions, poor fuel quality, etc., may illuminate
the light after engine start. The vehicle should be serviced
if the light stays on through several of your typical
driving cycles. In most situations, the vehicle will drive
normally and will not require towing.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
11. Electronic Park Brake Failure Indicator — If
Equipped
This light indicates the Electronic Parking
Brake system requires service.

12. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating properly.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
NOTE:Temperature readings in the orange range of the
gauge are acceptable under some high load condition. If
the gauge points to the H orEngine Temperature Hot
DID message appears a light and a single chime will
require driver correction.CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your

WARNING!(Continued)
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
13. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the conditionhas been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.
16. Driver Information Display (DID)
The odometer display shows the total distance the ve-
hicle has been driven.U.S. Federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. If your
odometer needs to be repaired or serviced, the repair
technician should leave the odometer reading the same
as it was before the repair or service. If she/he cannot do
so, then the odometer must be set at zero, and a sticker
must be placed in the door jamb stating what the mileage
was before the repair or service. It is a good idea for you
to make a record of the odometer reading before the
repair/service, so that you can be sure that it is properly
reset, or that the door jamb sticker is accurate if the
odometer must be reset at zero.
When the appropriate conditions exist, this Driver Infor-
mation Display (DID) messages. Refer to “Driver Infor-
mation Display” of your owners manual for more
information.

Engine Oil Life Reset
Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The “Oil Change Required” message
will display in the DID for five seconds after a single
chime has sounded, to indicate the next scheduled oil
change interval. The engine oil change indicator systemis duty cycle based, which means the engine oil change
interval may fluctuate, dependent upon your personal
driving style.
Unless reset, this message will continue to display each
time you cycle the ignition to the ON/RUN position. To
turn off the message temporarily, push and release the
OK button. To reset the oil change indicator system (after
performing the scheduled maintenance), refer to the
following procedure.
Oil Change Reset Procedure
1. Without pushing the brake pedal, push and release the
ENGINE START/STOP button and place the ignition
to the ON/RUN position (do not start the engine).
2. Fully push the accelerator pedal, slowly, three times
within 10 seconds.
