Ignition Positions
CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be injured or even killed. They could
operate power windows or other controls or even
make the vehicle move. Don't leave the keys in
the vehicle with children.
With the ignition key in the ignition, you can turn the
switch to five positions:
ACCESSORY (A): The accessory position lets you use
the radio and windshield wipers when the engine is off.
To use ACC, push in the key and turn it toward you.
Your steering wheel will stay locked.
LOCK (B): Before you put the key into the ignition
switch, the switch is in LOCK. It's also the only position
from which you can remove your key. This position
locks your ignition, steering wheel and transaxle. It's a
theft
-deterrent feature.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel. Use OFF if you must have your vehicle pushed
or towed.
RUN (D): This position is where the key returns after
you start your vehicle. With the engine off, you can
use RUN to display some of your warning and
indicator lights.
START (E): This position starts your engine.
A warning chime will sound if you open the driver's
door when the ignition is in OFF, LOCK or
ACCESSORY and the key is in the ignition.

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes your:

Turn Signal and Lane Change Indicator

Headlamp High/Low Beam Changer

Windshield Wipers

Windshield Washer

Cruise Control (If Equipped)

Flash
-to-Pass
Turn Signal and Lane Change Indicator
The turn signal has the following positions: two upward
(for right) and two downward (for left). These positions
allow you to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever will return automatically.
An arrow on the instrument
panel will flash in the
direction of the turn or
lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by
itself when you release it.
If the arrow flashes faster than normal as you signal a
turn or a lane change, a signal bulb may be burned out
and other drivers won't see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check for burned
-out bulbs and then check
the fuse (see ªFuses and Circuit Breakersº in the Index).

A chime will sound if you leave your turn signal on for
more than 3/4 mile (1.2 km).
Headlamp High/Low Beam Changer
To change your headlamps
from low beams to high
beams, or high to low, pull
the multifunction lever all
the way toward you. Then
release it.
When the high beams are on, this light on the instrument
panel also will be on.
Flash-to-Pass Feature
This feature lets you use your high-beam headlamps to
signal the driver in front of you that you want to pass. It
works even if your headlamps are off.
To use it, pull the turn signal lever toward you a little,
but not so far that you hear a click.
If your headlamps are off or on low beam, your
high
-beam headlamps will turn on. They'll stay on as
long as you hold the lever toward you and the
high
-beam indicator on the dash will come on. Release
the lever to turn the high
-beam headlamps ªflashº off.
Windshield Wipers
You control the windshield wipers by turning the band
marked WIPER. 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 cycle. If you want more
cycles, hold the band on MIST longer.
For steady wiping at low speed, turn the band to LO. For
high
-speed wiping, turn the band further, to HI. To stop
the wipers, turn the band to OFF.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain or

2-35
snow. Turn the band to choose the delay time. The
closer to LO, the shorter the delay between wipes.
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
damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.
Windshield Washer
At the top of the multifunction lever, there's a paddle with
the word PUSH on it. To spray washer fluid on the
windshield, push the paddle. The wipers will run for
several sweeps and then either stop or return to your preset
speed. See ªWindshield Washer Fluidº in the Index.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
The LOW WASH light on
your instrument panel
cluster will glow when the
fluid level is low.
Cruise Control (If Equipped)
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long trips.

Passenger Compartment Air Filter
The passenger compartment
air filter is located
underneath your hood just
below the windshield wiper
arm on the passenger side
(underneath the air inlet
grille) of the vehicle.
The filter traps most of the pollen from the air entering
the air conditioning module. Like your engine's air
cleaner filter, it may need to be changed periodically.
For information on how often to change the passenger
compartment air filter, see ªMaintenance Scheduleº in
the Index.
To change the passenger compartment air filter, use the
following steps:
1. Turn off the ignition when the windshield wipers are
in the up position.2. Raise the hood.
3. Remove (disconnect) the windshield washer pump
hose from the fender rail and air inlet grille.
4. Reposition the hood weatherstrip from the
passenger's side of the vehicle (peel back halfway to
center).
5. Remove (disconnect) the air inlet grille retainers.
6. Remove (disconnect) the air inlet grille.
7. Remove (disconnect) the passenger compartment
air filter.
8. Then install the new air filter. For the type of filter to
use, see ªNormal Maintenance Replacement Partsº
in the Index.
9. Reposition the air inlet grille.
10. Replace the air inlet grille retainers.
11. Reposition the hood weatherstrip.
12. Reconnect the windshield washer pump hose to the
fender rail air inlet grille.
13. Close the hood.
14. Return the windshield wipers to the park position.

Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See ªWiper Blade
Checkº in Section 7 of this manual under Part B ªOwner
Checks and Servicesº for more information.
1. Turn on the wipers to the low
-wipe setting.
2. Turn off the ignition while the wipers are at the
outer positions of the wiper pattern. The blades are
more accessible for removal/replacement while in
this position.
3. Pull the windshield wiper arm 3 to 4 inches (7.5 to
10 cm) away from the windshield.
4. While holding the wiper arm away from the glass,
push the release clip from under the windshield
wiper arm connecting point and slide the blade
assembly down toward the glass to remove it from
the wiper arm.
5. Slide the new wiper blade securely on the wiper arm
until you hear the release clip ªclickº into place.
For wiper blade replacement length and type, see
ªNormal Maintenance Replacement Partsº in the Index.

6-59 Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center. An electrical overload
will cause the lamps to go on and off, or in some cases
to remain off. If this happens, have your headlamp
system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself. This
greatly reduces the chance of fires caused by
electrical problems.Look at the silver
-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
Instrument Panel Fuse Block
Some fuses are located in a
fuse block on the
passenger's side of the
instrument panel. Pull off
the cover labeled FUSES to
expose the fuses.
