INSTRUMENT CLUSTER DESCRIPTION
1. Check Gauges
This light illuminates when the Voltmeter, Engine
Oil Pressure or Engine Coolant Temperature
gauges indicate a reading either too high or too low.
Examine the gauges carefully, and follow the instructions
contained below for each indicated problem.
NOTE:When the ignition switch is turned to OFF, the
Fuel Gauge, Voltmeter, Oil Pressure and Engine Coolant
Temperature gauges may not show accurate readings.
When the engine is not running, turn the ignition switch
to ON to obtain accurate readings.
2. Voltmeter
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. Ifthe pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gaugesº indicator will illuminate
and a single chime will sound.
NOTE:
²The voltmeter may show a gauge fluctuation at vari-
ous engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of
the cycling operation is controlled by the engine
control module. Post-heat operation can run for sev-
eral minutes, and then the electrical system and volt-
meter needle will stabilize.
²The cycling action will cause temporary dimming of
the headlights, interior lights, and also a noticeable
reduction in blower motor speed.

5. Airbag Indicator Light

when the ignition is first turned on. If the light stays on,
flickers or comes on while driving, have the airbag
system checked by an authorized dealer.6. High Beam Indicator
This indicator shows that headlights are on high
beam.
7. Seat Belt Reminder Light
When the ignition switch is first turned ON, this
light will turn on for five 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 seat belt remains
unbuckled, the Seat Belt Warning Light will flash or
remain on continuously. Refer to9Enhanced Driver Seat
Belt Reminder System (BeltAlertt)9under ªOccupant
Restraintsº in section 2.
