Turn Signal/Multifunction Lever
The multifunction lever located on the left side of the
steering column includes the following:
Turn and Lane-Change Signals
Headlamp High/Low-Beam Changer
Flash-to-Pass
Windshield Wipers
Windshield Washer
Cruise Control
Turn and Lane-Change Signals
To signal a turn, move the turn signal/multifunction lever
up or down. The lever returns to its original position
when the turn is completed.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, raise or lower the turn signal/
multifunction lever until the arrow starts to ash. Hold it
there until the lane change is completed. The lever will
return to its original position when released.
Arrows that ash rapidly when signaling for a turn or
lane change, or that fail to work, may indicate a
burned-out signal bulb or fuse. Other drivers will not see
the signal. SeeFront Turn Signal and Parking Lamps
on page 5-48andTaillamps, Turn Signal, and
Stoplamps on page 5-50for turn signal bulb replacement
procedures. Also seeFuses and Circuit Breakers on
page 5-91for location of fuses.
A chime will sound if the turn signal is left on for more
than 3/4 mile (1.2 km).

Headlamp High/Low-Beam Changer
To change the headlamps from low beams to high
beams, or high to low, pull the multifunction lever until
a click is heard, then release it.
This indicator light on the
instrument panel cluster
will come on while the
high-beam lamps are on.
Flash-to-Pass
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 the headlamps are off. Pull the turn
signal lever toward you a little, but not so much that you
hear a click.
If the headlamps are off or on low-beam, the high-beam
headlamps will turn on. They will stay on as long as
you hold the lever toward you. The high-beam indicator
on the instrument panel cluster will come on. Release
the lever to return it to the normal operation.
Windshield Wipers
To operate the windshield wipers turn the band located
on the multifunction lever upward or downward.
WIPER:Turn this band to control the windshield wipers.
OFF:Turn the band to OFF to turn off the
windshield wipers.
LO (Low Speed):Turn the band away from you
to LO and past the delay settings for steady wiping at
low speed.
HI (High Speed):Turn the band away from you, to HI,
and past the delay settings for steady wiping at a
high speed.
(Delayed Wiping):Turn the band away from you,
just past OFF, to one of the ve delayed settings,
to choose the length of intervals between each wiping
cycle. The further the band is turned upward, toward LO,
the shorter the delay will be. Select one of these
settings for light rain or snow.

You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even
several seconds, for your eyes to re-adjust to the dark.
When you are faced with severe glare, as from a
driver who does not lower the high beams, or a vehicle
with misaimed headlamps, slow down a little. Avoid
staring directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a lm caused by dust. Dirty glass makes
lights dazzle and ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as your headlamps should
be checked regularly for proper aim, so should your
eyes be examined regularly. Some drivers suffer from
night blindness — the inability to see in dim light — and
are not even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you cannot stop, accelerate, or turn as well
because your tire-to-road traction is not as good as on
dry roads. And, if your tires do not have much tread
left, you will get even less traction. It is always wise to
go slower and be cautious if rain starts to fall while
you are driving. The surface may get wet suddenly when
your reexes are tuned for driving on dry pavement.

Headlamp Aiming
The vehicle has a headlamp system equipped with
horizontal and vertical aim indicators. The aim has been
pre-set at the factory and should need no further
adjustment. This is true even though the vertical and
horizontal aim indicators may not fall exactly on
the “0” (zero) marks on their scales.
If the vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment may be
necessary if it is difficult to see lane markers, for
horizontal aim, or if oncoming drivers ash their high
beams at you, for vertical aim. If you believe the
headlamps need to be re-aimed, we recommend that
you take it to your dealer for service; however, it is
possible for you to re-aim the headlamps as described
in the following procedure.
Notice:To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure to follow these instructions could cause
damage to headlamp parts.To check the aim, the vehicle should be properly
prepared as follows:The headlamps must be off for one hour prior to
aiming and must remain off during this procedure.
The vehicle must have all four tires on a perfectly
level surface.
If necessary, pads may be used on an uneven
surface to help level the vehicle.
The vehicle should not have any snow, ice or mud
attached to it.
The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
There should not be any cargo or loading of the
vehicle. It should however, have a full fuel tank and
one person or 160 lbs (75 kg) on the driver’s seat.
Close all doors.
Tires should be properly inated.
Rock the vehicle to stabilize the suspension.
