Reading La ~ ~ ps
Press the button near each
lamp to turn the reading
lamps
on and off.
The lamps can also be swiveled
to point in the
desired direction.
Driver Information System
This system displays the outside air temperature,
compass direction and trip information in the
overhead console.
USMET The USMET (United Statedmetric) button
allows you to switch the display between
the English
and metric system.
MODE: The MODE button can be used to toggle
between three modes
of operation: OFF, COMP/TEMP
and TRIP.
OFF: This button turns the system off.
COMP/TEMP: The display provides the outside
temperature and one
of eight compass readings to
indicate the direction the vehicle is facing.
Before you turn on the ignition and move
the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the outside
temperature is
37°F (3°C) or lower, the display will
toggle between the word ICE and the current
temperature every eight seconds. This is a warning
to
the driver that road conditions may be icy, and that
appropriate precautions should be taken.
The compass is self-calibrating,
so it does not need to be
manually set. However, if C (Calibration) is displayed, the
compass will need
to be calibrated. You may also place the
compass in a noncalibrated mode by pressing and holding
the MODE and USMET buttons simultaneously while in
the COMPREMP mode. After about 10 seconds, the
compass will display
C and you can release the buttons.
Drive
the vehicle in a complete 360" circle three times at
a speed of less than 5 mph (8 km/h), and the compass will
function normally. Once the calibration is complete, the
display will return
to a compass reading.

Accessory Power Outlets
With the accessory power outlets, you can plug in
auxiliary electrical equipment. There are four accessory
power outlets located throughout the vehicle. Two are
near the lower center part
of the instrument panel, one is
located in
the lower rear of the center console and the
other is located in
the rear of the vehicle in the air
inflator compartment. Follow the proper installation
instructions that are included with any electrical
equipment you install.
These circuits are protected by
a fuse and have
maximum current levels.
NOTICE:
When using the accessory power outlets,
maximum electrical load must not exceed
20 amps. Always turn off any electrical
equipment when not in use. Leaving electrical
equipment on for extended periods will drain
your battery.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you
if there is an electrical problem. The
system check includes
the air bag sensors, the air bag
module, the wiring and the diagnostic module. For more
information
on the air bag system, see “Air Bag” in
the Index.
This light will come on
when you start your engine,
and
it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may
not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when
you turn the ignition key to RUN. If the
light doesn’t come
on then, have it fixed so it will be
ready to warn
you if there is a problem.
Charging System Indicator Light
The charging system light
will come on briefly when
you turn on the ignition, but
’ the engine is not running,
as a check to show you it
is working.
It should go out once the engine
is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system.
It could indicate that
you have problems with
a generator drive belt, or
another electrical problem. Have
it checked right away.
Driving while this light
is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio

Voltmeter Gage
I
When your engine is not
running, but the ignition is
on
(in RUN), this gage
shows your battery’s state of
charge in
DC volts.
When the engine is running,
the gage shows the
condition of
the charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings
in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition
is normal since the
charging system
is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings
in either warning zone indicate a possible
problem
in the electrical system. Have the vehicle
serviced as soon
as possible.

Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The light
will stay on
if your parking brake doesn’t release fully.
If it stays on after your parking brake is fully released, it
means you have a brake problem.
If the light comes on while you are driving, pull off the
road and stop carefully.
You may notice that the pedal is
harder to push.
Or, the pedal may go closer to the floor.
It may take longer to stop.
If the light is still on, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
Your vehicle’s hydraulic brake system is divided into
two parts.
If one part isn’t working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come
on
briefly when you turn the
ignition key to
RUN. If it
it fixed so it will be ready
to warn you if there’s
a problem.

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay
on
for several seconds.
That’s normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t on,
you still have brakes, but you
don’t have anti-lock brakes. If the regular brake system
warning light is
also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier
in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you
if there is a problem.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into
the
red area, your engine is
too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions,
you should pull off the road, stop your
vehicle and turn off
the engine as soon as possible.
The “Problems on the Road” section
of this manual
shows you what to do. See “Engine Overheating”

the fuel gage tells you
about how much fuel you
have remaining.

owners ask about. None
of these
show a problem with your fuel gage:
