Reading Lamps
If your vehicle has reading
lamps, press the button located next
to the lamp to
turn it on. The lamps can be adjusted
to point in
the direction you want.
Press the button again to turn the lamp
off.
Your vehicle may also have reading lamps in other
locations.
To turn on or off, press the button located next
to the lamp. The lamps are fixed and cannot be
adjusted.
Battery Run-Down Protection
This feature shuts off the dome, reading, glove box and
underhood lamps
if they are left on for more than
20 minutes when the ignition is in lock. This will keep
your battery from running down.
Accessory Power Outlets
With accessory power outlets you can power auxiliary
electrical equipment such as a cellular telephone or
CB
radio.
Your vehicle is equipped with many accessory power
outlets. The front outlet is located on the instrument
panel behind a hinged door.
There is also an outlet located in the center console.
Press the button on the side of the console door
to access the outlet. See Center Console Storage Area
on page 2-42 for more information. Addditional power
outlets may be located on the back of the center console
above the cupholder door and in the rear cargo area
on the passenger side.

If the word OFF or the off symbol is lit on the air bag
status indicator,
it means that the passenger sensing
system has turned
off the right front passenger’s frontal
air bag. See Passenger Sensing System on page
7 -8 7
for more on this, including important safety information.
If, after several seconds, all status indicator lights
remain on, or
if there are no lights at all, there may be a
problem with the lights or the passenger sensing
system. See your dealer for service.
__ -he ofl ..jdicator and the air bag readiness
light ever come on together, it means that
something may be wrong with the air bag
system.
If this ever happens, have the vehicle
serviced promptly, because an adult-size
person sitting in the right front passenger seat
may not have the protection of the frontal air
bag. See “Air Bag Readiness Light” in the
Index.
Charging System 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.
When this light comes on the DIC will also display the
battery not charging message. See
DIC Warnings
and Messages
on page 3-52.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and air conditioner.

Voltmeter Gage
When your engine is not
running, but the ignition is
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
With the ignition on, the brake system warning light will
flash when you set the parking brake. The light will
flash
if the parking brake doesn’t release fully. If you try
to drive with the parking brake engaged, a chime will
sound when the vehicle speed is greater than 3 mph
(5 km/h).
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 and a chime sounds there
could be a brake problem. Have your brake system
inspected right away.

If none of the above steps have made the light turn off,
have your dealer or qualified service center check
the vehicle. Your dealer has the proper test equipment
and diagnostic
tools to fix any mechanical or electrical
problems that may have developed.
€missions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs
to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need
to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection
if the Check
Engine light is on or not working properly.
Your vehicle will not pass this inspection
if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen
if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed
to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving.
If you have done this and your vehicle still does
not pass the inspection for lack of
OBD
system readiness, see your dealer or qualified service
center to prepare the vehicle for inspection.
Oil Pressure Gage
_I
United States Canada
The oil pressure gage shows the engine oil pressure in
psi (pounds per square inch) when the engine is
running. Canadian vehicles indicate pressure in kPa
(kilopascals).
Oil pressure may vary with engine speed, outside
temperature and
oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
