DESCRIPTION
1. Voltmeter
Indicates available battery voltage and
charging system operation. The lower red

be too low to start the engine. With the engine
running, the normal operating range is between
11 and 15 volts. Prolonged gauge readings be-
tween 9-11 (undercharge) or above 15 (over-
charge) indicate possible malfunction of the alter-
nator, voltage regulator, or battery. See your
authorized dealer if such signs occur.

signals when the multi-function control lever
is operated.
3. Tachometer

trol lever towards the steering wheel to

beam.
5. Airbag Warning Light

8 seconds when the ignition is first turned
ON. If the light does not turn on, stays on
or comes on while driving, have the airbag
system checked by an authorized dealer.
6. Speedometer
Indicates vehicle speed.
7. Oil Pressure Gage
Indicates the engine oil pressure. This
gauge does not measure oil level. Pres-
sure varies with engine speed, tempera-

indicate a possible malfunction. Seek authorized
service.

tem" in Section 2 of this manual for
more information.
9. Malfunction Indicator Light
This light is part of an onboard diagnos-
tic system called OBD that monitors
engine and automatic transmission con-
trol systems. The "Malfunction Indicator
Light" will illuminate briefly when the
ignition key is in the ON position before engine
start. If the bulb does not come on when turning
the key from OFF to ON, have the condition
checked promptly.
Certain conditions such as a loose gas cap, poor
fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the
light stays on through several typical driving
cycles. In most situations, the vehicle will drive
normally and will not require towing.
The "Malfunction Indicator Light" will flash to alert
the driver of serious conditions that could lead to
immediate loss of power or severe catalytic con-
verter damage. The vehicle should be serviced as
soon as possible if this occurs.
10. Cruise Indicator Light
This indicator lights when the elec-
tronic speed control system is turned
on.
