Windshield Wipers
: Mist
: Off
You control the windshield wipers by turning the band
with the wiper symbol on it.
For a single wiping cycle, turn the band to mist. Hold it
there until the wipers start. Then let go. The wipers will
stop after one wipe. If you want more wipes, hold the
band on mist longer.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain or
snow. Turn the band to choose the delay time. The
closer to the top of the lever, the shorter the delay.
For steady wiping at low speed, turn the band away
from you to the first solid band past the delay settings.
For high
-speed wiping, turn the band further, to the
second solid band past the delay settings. To stop the
wipers, move the band to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they're frozen to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.
Rainsense
Wipers (If Equipped)
Your vehicle may be equipped with Rainsense
windshield wipers. When active, these wipers are able to
detect moisture on the windshield and automatically turn
on the wipers.
The moisture sensor is located next to the inside
rearview mirror and is mounted on the windshield.
To turn on the Rainsense feature, the wipers must be set
to one of the five delay settings on the multifunction
lever. Each of the five settings adjusts the sensitivity of
the rainsensor. For more wipes, select the higher
settings; for fewer wipes, select the lower settings
located closer to off on the multifunction lever.
The rainsensor will automatically control the frequency
of the wipes from off to high speed according to the
weather conditions. The wipers can be left in a rainsense
mode even when it is not raining.
NOTICE:
Turn the multifunction lever to off to avoid
wiper damage when going through an automatic
car wash.

Exterior Lamps
Your exterior lamps knob is
on the driver's side of your
instrument panel.
Turn the knob clockwise to the parking lamps
symbol to manually turn on the following:

Parking Lamps

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights
Turn the knob clockwise to the master lamps
symbol to turn on all the lamps listed as well as
the headlamps.
Turn the knob all the way counterclockwise to this
symbol to turn off the lamps and put the system in
automatic headlamp mode.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be on.
Your vehicle is equipped with a light sensor on the top
of the instrument panel. Be sure it is not covered or the
system will be on whenever the ignition is on.
The system may also turn on your lights when driving
through a parking garage, heavy overcast weather or a
tunnel. This is normal.

2-45
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems so that
driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the light
sensor sees a change in lighting lasting longer than
the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake,
or until you shift out of park.
You may be able to turn off your automatic headlamp
system. See ªDaytime Running Lamps (DRL)º later
in this section for more information.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver's door
is open and your ignition is in LOCK or ACCESSORY.
To turn the tone off, turn the knob all the way
counterclockwise. In the automatic mode, the headlamps
turn off once the ignition key is in LOCK.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.
The DRL system will make your headlamps come
on at reduced brightness when the following conditions
are met:

The ignition is on,

the exterior lamps knob is in automatic
headlamp mode,

the light sensor detects daytime light, and

the transmission is not in PARK (P).
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.
When it begins to get dark, the headlamps
will automatically switch from DRL to the
regular headlamps.

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 modules, the wiring and the crash sensing and
diagnostic module. For more information on the air
bag system, see ªAir Bagº in the Index.
This light will come on
when you start your vehicle,
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
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
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.

Automatic Operation
Press the AUTO button to set the system to
automatically control the air delivery mode, fan speed,
air temperature and recirculation operations. Whenever
you press AUTO, the display will change to show the
current driver's set temperature, automatic air delivery
mode and fan speed. Press the AUTO button again
within five seconds and the display will show the
passenger's set temperature. After five seconds the
display will change to the EXT (external) temperature
outside the vehicle.
When AUTO is selected, the air conditioning operation
and air inlet will be automatically controlled. The air
conditioning compressor will run when outside
temperature is over approximately 40
F (4
C).
The air inlet will normally be set to outside air. If it's
hot outside, the air inlet will automatically switch
to recirculated inside air to help quickly cool down
your vehicle.
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), thesystem 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. Pressing the fan switch will override this
delay and change the fan to a selected speed.

Cassette Tape Messages
(CHK TAPE): If CHK TAPE appears on the radio
display, the tape won't play because of one of the
following errors.

The tape is tight and the player can't turn the tape
hubs. Remove the tape. Hold the tape with the
open end down and try to turn the right hub
counterclockwise with a pencil. Turn the tape over
and repeat. If the hubs do not turn easily, your tape
may be damaged and should not be used in the
player. Try a new tape to make sure your player is
working properly.

The tape is broken. Try a new tape.

The tape is wrapped around the tape head. Attempt
to get the cassette out. Try a new tape.(CLEAN): If this message appears on the display, the
