Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
Manual Front Seat
CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver's seat while the vehicle is
moving. The sudden movement could startle and
confuse you, or make you push a pedal when you
don't want to. Adjust the driver's seat only when
the vehicle is not moving.
You can adjust the seat
with this lever located at
the front of the seat.
Slide the lever toward the passenger's side to unlock the
seat. Using your body, slide the seat to where you want
it. Then, release the lever and try to move the seat with
your body in order to make sure the seat is locked
into place.

2-11
Passlock
Your vehicle is equipped with the Passlock
theft
-deterrent system.
Passlock is a passive theft
-deterrent system. Passlock
enables fuel if the ignition lock cylinder is turned with a
valid key. If a correct key is not used or the ignition lock
cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will
go off approximately five seconds after the key is turned
to RUN.
If the engine stalls and the SECURITY light flashes,
wait until the light stops flashing before trying to restart
the engine. Remember to release the key from START
as soon as the engine starts.
If the engine is running and the SECURITY light comes
on, you will be able to restart the engine if you turn the
engine off. However, your Passlock system is not
working properly and must be serviced by your dealer.
Your vehicle is not protected by Passlock at this time.
You may also want to check the fuses (see ªFuses and
Circuit Breakersº in the Index). See your dealer
for service.
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate
ªbreak
-in.º But it will perform better in the
long run if you follow these guidelines:

Keep your speed at 55 mph (88 km/h) or
less for the first 500 miles (805 km).

Don't drive at any one speed
-- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first
200 miles (322 km) or so. During this time
your new brake linings aren't yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking
-in guideline every
time you get new brake linings.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.

2-29
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:

Turn and Lane Change Signals

Headlamp High/Low
-Beam Changer

Windshield Wipers

Windshield Washer

Cruise Control (If Equipped)
Turn and Lane Change Signals
The turn signal has two upward (for right) and
two downward (for left) positions. 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 located on the
instrument panel cluster 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 you move the lever all the way up or down, and the
arrow flashes at twice the normal rate, a signal bulb
may be burned out and other drivers may not 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 a blown
fuse (see ªFuses and Circuit Breakersº in the Index).

2-30 Headlamp High/Low-Beam Changer
To change the headlamps from low to high beam or high
to low beam, pull the multifunction lever all the way
toward you. Then release it.
When the high beams are
on, this light located on the
instrument panel cluster
also will be on.
Windshield Wipers
You control the windshield
wipers by turning the knob
with the wiper symbol on it.For a single wiping cycle, turn the knob 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
knob on MIST longer.
You can set the wiper speed for a long or short delay
between wipes. Use this setting in light rain or snow.
Turn the knob to choose the delay time. The closer to
LOW, the shorter the delay.
For steady wiping at low speed, turn the knob to the LOW
position. For high
-speed wiping, turn the knob further,
to HIGH. To stop the wipers, turn the knob to OFF.
Damaged wiper blades may prevent you from seeing
well enough to drive safely. To avoid damage, be sure to
clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, carefully
loosen or thaw them. If your blades do become
damaged, get new blades or blade inserts.
Heavy ice or snow can overload your wipers. The
windshield wiper motor is protected from overload by a
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. Although protected from electrical overload,
overload due to heavy snow, etc. may cause wiper
linkage damage. Always clear ice and heavy snow from
the windshield before using your windshield wipers.

2-43 Accessory Power Outlets
Two accessory power outlets are located near the
cigarette lighter. Use these outlets to power mobile
telephones or other devices designed to operate with
vehicle electrical systems.
Certain power accessory plugs may not be compatible to
the power accessory outlet and could result in blown
vehicle or adapter fuses. If you experience a problem,
see your dealer for additional information on the power
accessory plugs.
NOTICE:
Power outlets are designed for accessory plugs
only. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of
the power outlet can cause damage not covered
by your warranty.
Sun Visors
To block out glare, you can swing down the visors. You
can also swing them out to help block glare at the front
and side windows.
Some visors have an extender on the inside edge. When
the visor is down, pull the extender out for extra glare
coverage at the front or side.
Some visors have mirrors with lamps. If the mirror has
lamps, they will come on when you lift the mirror cover.
