Rear Air Conditioning System
If your vehicle has the rear air conditioning system
it has two fan speed selectors. One fan speed
selector is located in the front overhead console
and the other is located in the headliner above the
second row seats. The rear air conditioning
system is designed to provide cooled air only.
To operate the rear system using the front control,
just turn the knob to the fan position you want.
To use the rear control, rst turn the front control
to AUX, then the rear control can be used to
increase and decrease the airow.
Passenger Compartment Air Filter
The passenger compartment air lter helps remove
dust and pollen from the air entering the vehicle.
Like the vehicle’s engine air cleaner/lter, it
needs to be changed periodically. For how often
to change the passenger compartment air
lter, seeScheduled Maintenance on page 471.
The passenger compartment air lter is located
underneath the hood below the windshield
wiper arm on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 356
for more information on location.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on your vehicle. The pictures will
help you locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As
you will see in the details on the next few
pages, some warning lights come on briey when
you start the engine just to let you know they
are working. If you are familiar with this section,
you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let
you know when there is a problem with your
vehicle.
When one of the warning lights comes on and
stays on while you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Waiting to do repairs can be costly – and even
dangerous. So please get to know your warning
lights and gages. They are a big help.
Your vehicle also has a Driver Information Center
(DIC) that works along with the warning lights
and gages. SeeDriver Information Center (DIC)
on page 214for more information.

Speedometer and Odometer
The speedometer lets you see your speed
in both miles per hour (mph) and kilometers
per hour (km/h). See “SPEEDOMETER” under
DIC Controls and Displays on page 215for more
information.
The odometer mileage can be checked without the
vehicle running. Your vehicle’s odometer works
together with the driver information center.
You can set a Trip A and a Trip B odometer. See
“Trip Fuel” underDIC Controls and Displays on
page 215for more information.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Tachometer
This gage indicates the engine speed in
revolutions per minute (rpm).
Engine Speed Limiter
This feature prevents the engine from operating at
too many revolutions per minute (rpm). When
the engine’s rpms are too high, the throttle
is closed to reduce speed. If this is not sufficient,
then the fuel supply to the engine will be
limited. When the rpms return to normal, the fuel
supply will return to normal. This helps prevent
damage to the engine.

Charging System Light
This light will come on
briey when the ignition
is turned to ON to
show that it is working.
It should turn off 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 there is a problem with the
generator, generator drive belt or another electrical
problem. Have is 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 unnecessary accessories,
such as the radio and air conditioner.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not 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 is a brake
problem. Have your brake system inspected
right away.
This light should come on briey when you turn
the ignition key to ON. If it does not come on then,
have it xed so it will be ready to warn you if
there is a problem.

When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. The light will stay on if your parking brake
does not 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 oor. It may take longer to
stop. If the light is still on, have the vehicle towed
for service. SeeTowing Your Vehicle on
page 328.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
With the Anti-Lock
Brake System (ABS),
the light will come on
when your engine is
started and stay on for
several seconds. This is
normal.
If the ABS warning light comes on and stays on,
there may be a problem with the anti-lock
portion of the brake system. If the brake system
warning light is not on, you still have brakes,
but you do not have anti-lock brakes. SeeBrake
System Warning Light on page 204for more
information.
If the light stays on, turn the ignition to OFF. If the
light comes on when you are driving, stop as
soon as possible and turn the ignition off. Then
start the engine again to reset the system. If
the light still stays on, or comes on again while
you are driving, your vehicle needs service.
205

If the regular brake system warning light is not on,
you still have brakes, but you do not have
anti-lock brakes. If the regular brake system
warning light is also on, you do not have anti-lock
brakes and there is a problem with your regular
brakes. SeeBrake System Warning Light on
page 204for more information.
The ABS warning light should come on briey
when you turn the ignition key to ON. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
Your vehicle has a
traction control system
warning light.
This light will come on when your traction control
system is limiting wheel spin. You may feel or
hear the system working, but this is normal.If the traction control system warning light comes
on and stays on for an extended period of
time when the system is turned on, your vehicle
needs service. SeeTraction Control System (TCS)
on page 281for more information.
Engine Coolant Temperature
Warning Light
This light tells you that
your engine is very hot.
This light will come on when you rst start the
vehicle as a check to let you know that the light is
working. It will go out after a few seconds. If the
light does not come on, the bulb may be burned out.
See your dealer to have it corrected.
If the light does not go out or if the light comes on
and stays on while you are driving, your vehicle
may have a problem with the cooling system.
206

You should stop the vehicle and turn off the
engine as soon as possible to avoid damage to
the engine. A warning chime will sound when this
light is on, also.
SeeEngine Overheating on page 372.
Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
It can be used to see when your engine has
warmed up and to make sure your cooling system
is operating properly. If the gage pointer moves into
the shaded area, the engine coolant is too hot and
the engine coolant temperature warning light will
come on. SeeEngine Overheating on page 372for
more information.
Tire Pressure Light
If your vehicle has this
light, it will come on
briey when you turn the
ignition on.
This light will also come on when one or more of
your tires are signicantly underinated.
A CHECK TIRE PRESSURE DIC message will
accompany the light, seeDIC Warnings and
Messages on page 220
