The air inflator kit is located in the glove compartment.
The kit includes a 22
-foot (6.7 m) hose with three
nozzle adapters.
To use the air inflator attach the appropriate nozzle
adapter to the end of the hose if required. Then attach
that end of the hose to the object you wish to inflate.
Attach the other end of the hose to the outlet.
Press and release the switch to turn the air inflator
on. The indicator light will remain on when the inflator
is running.
The system has an internal clock to prevent overheating.
The system will allow about five minutes of running
time, then the compressor will stop. The indicator light
will then begin to flash. When the indicator is off, the
inflator can be started again by pressing the switch. If
the compressor is still hot, it may only run for a short
time before shutting off again.Press and release the switch to turn the inflator off.
Place the inflator kit tools in the pouch and store it
properly. Remove the inflator hose from the outlet
during loading and unloading. Load leveling will not
function with the inflator hose attached to the inflator
outlet. See ªElectronically Controlled Air Suspension
Systemº in the Index.
To reinstall the cover, line up the tabs at the back of the
cover, put it in place and latch the tabs.
A continuous flashing indicator light may also indicate a
malfunction in the air suspension system. See
ªElectronically Controlled Air Suspension Systemº in
the Index.
CAUTION:
Inflating something too much can make it
explode, and you or others could be injured. Be
sure to read the inflator instructions, and inflate
any object only to its recommended pressure.

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
ªBrake System Warning Lightº 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
United States Canada
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, 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.
See ªEngine Overheatingº in the Index for
more information.

2-84
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady,
see ªIf the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index.
The diagnostic system can determine if the fuel cap
has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

To find your comfort setting, start with a 74
F (23
C)
temperature setting and allow about 20 minutes for the
system to regulate. Turn the driver's or passenger's side
temperature knob clockwise or counterclockwise to
adjust the temperature setting as necessary. If you
choose the temperature setting of 60
F (15
C), the
system will remain at the maximum cooling setting
and fan speed. If you choose the temperature setting of
90
F (32
C), the system will remain at the maximum
heat setting and fan speed. Choosing either maximum
setting will not cause the system to heat or cool any
faster.
Be careful not to cover the sensor located on the top of
the instrument panel near the windshield. This sensor
regulates air temperature based on sun load, and also
turns on your headlamps.
The EXT (exterior) temperature sensor is located in the
front of the vehicle behind the grille. The displayed
temperature is most accurate after the vehicle has been
moving for a few minutes. If the vehicle is stopped and
then restarted within 2 1/2 hours, the sensor will be hot
from the engine heat. In this case, the temperature first
displayed will continue to be the temperature that was
displayed before the vehicle was turned off. The display
will update after the vehicle has been moving for a few
minutes and the sensor has a chance to cool down to the
actual temperature.To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the engine coolant
temperature. Pushing the fan switch will override this
delay and change the fan to a selected speed.
Manual Operation
You may manually adjust the air delivery mode or fan
speed. Use the mode button to cycle through the
following four air delivery modes:
(Panel): This setting will deliver air to the
instrument panel outlets.
(Bi-Level): This setting will deliver warmer air to
the floor and cooler air to the instrument panel outlets.
(Floor): This setting will deliver air to the
floor outlets.
(Defog): This setting will deliver air to the floor
and windshield outlets.
OFF: Press this button to turn the system off. Some
fresh air will continue to flow through the vehicle from
the floor outlets. The system will try to maintain the
previously chosen temperature setting.

INFO: If the current station has a message, the INFO
icon will appear on the display. These text messages are
from the RDS broadcaster to the listening public and
may be general information such as artist and song title,
call in phone numbers, etc. Press this button to see
the message. If the whole message does not appear
on the display, parts of the message will appear every
three seconds until the message is completed. To scroll
through the message at your own speed, press the INFO
button again for less than one second. A new group of
words will appear on the display. Once the complete
message has been displayed, the INFO icon will
disappear from the display until another new message is
received. The old message can be displayed by pressing
the INFO button until a new message is received or a
different station is tuned to.
TRAF: Press this button to receive traffic
announcements. If the current tuned station does not
broadcast traffic announcements, the radio will seek
to a station that does. The TRAF icon will flash on the
display. When the radio finds a station that broadcasts
traffic announcements, it will stop. If no station is found,
NO TRAF will appear on the display.
Your radio can be programmed to interrupt the playback
of a cassette tape, CD or FM radio by enabling the
traffic interrupt feature. Press the TRAF button once toseek to an RDS station that supports the traffic interrupt
feature if the current tuned station does not. The TRAF
icon will flash on the display when seeking for a station
that supports traffic interrupt. When the traffic interrupt
feature is on, TRAF will appear on the display.
When a traffic announcement comes on the tuned radio
station, you will hear it, even if the volume is muted or a
cassette tape or compact disc is playing. The TRAF icon
and TRAFFIC will appear on the display while the
traffic announcement plays. If the cassette tape or
compact disc player was being used, the tape or compact
disc will stay in the player and resume play at the point
where it stopped.
Playing a Cassette Tape
Your tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this
player. The longer side with the tape visible should face
to the right. If the ignition is on, but the radio is off, the
tape can be inserted and will begin playing. A tape
symbol is shown on the display whenever a tape is
inserted. If you hear nothing but a garbled sound, the
tape may not be in squarely. Press EJT to remove the
tape and start over.
