When the multi-function control lever is in the parklight,
headlights, or AUTO position (if equipped), rotating the
center portion of the lever up and down will increase and
decrease the brightness (dimmer control) of the instru-
ment panel lights. Full daytime brightness on all elec-
tronic displays (odometer, overhead console, radio, and
Automatic Climate Control (if equipped) is obtained by
rotating the center portion of the control to the first
detent above the dimmer range. Rotating the control to
the second detent above the dimmer range turns theinterior lights on. Rotating the control to the ªOffº
(extreme bottom) position disables all the interior lights,
even when the doors and liftgate are open. While in the
ªOffº position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.

CAUTION!
Electrical Outlet Use With Engine Off
²Many accessories that can be plugged in draw
power from the vehicle's battery, even when not
in use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle's battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
²Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
²After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
generator to recharge the vehicle's battery.
GLOVE COMPARTMENT
The glove compartment light will remain on if the glove
box door is not securely closed, causing an unnecessary
drain on the battery.
CUP HOLDERS
In the center console there are two cup holders for the
front seat passengers.

INSTRUMENT CLUSTER DESCRIPTION
1. Voltmeter
Indicates available battery voltage and charging
system operation. The lower red zone shows that
the battery charge may be too low to start the engine.
With the engine running, the normal operating range is
between 11 and 15 volts. Prolonged gage readings be-
tween 9-11 (undercharge) or above 15 (overcharge) indi-
cate possible malfunction of the generator, voltage regu-
lator or battery. See your dealer if such signs occur.
2. Turn Signal Indicator Light
The arrows will flash in unison with the exterior
turn signals, when using the multi-function control
lever. When the hazard warning system is activated, both
the indicator lights will flash simultaneously.
3. Tachometer
Indicates the engine speed in revolutions per minute.
CAUTION!
Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur.

7. Oil Pressure Gage
Indicates the engine oil pressure. This gage does
not measure oil level. Pressure varies with engine
speed, temperature, and oil viscosity. Normal oil pressure
will be midway between the lowest and highest limit
marks.
8. Sentry Key Indicator Light Ð If Equipped
Refer to ªSentry Key Immobilizer Systemº in
Section 2 of this manual for more information.
9. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD II which monitors engine and auto-
matic transmission control systems. This light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the ignition key from OFF to ON, have the
condition checked promptly.Certain conditions such has a loose or missing 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.
When the engine is running, the ªMalfunction Indicator
Lightº may flash to alert of serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
10. Cruise Indicator Light
This indicator lights when the electronic speed
control system is turned ON.
11. Check Gages Warning Light
This light illuminates when the voltmeter, oil
pressure, or temperature gages indicate a reading

13. Transmission Over Temperature Warning Light
This light indicates that there is excessive transmis-
sion fluid temperature that might occur with severe
usage such as trailer towing or snow plowing. If this lightcomes on, stop the vehicle and run the engine at idle or
faster, with the transmission in N (Neutral) until the light
goes off.
14. Temperature Gage
Indicates engine coolant temperature. Any read-
ing within the normal range indicates that the
cooling system is operating satisfactorily.
The gage pointer will likely indicate a higher temperature
(above center scale) 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.
If the pointer rises to the 260É (Hot) mark, pull over and
stop the vehicle. Do not turn the engine off. Idle the
vehicle with the air conditioning turned off, until the
