Horn
Press the horn symbols on the steering wheel pad to
sound the horn.
Tilt Wheel
A tilt wheel enables the position of the steering wheel to
be adjusted.
The lever that lets the steering wheel tilt is located on
the outboard side of the steering column.
To tilt the steering wheel,
hold it and pull the lever.
Move the steering wheel to
a comfortable driving
position and release the
lever to lock it into place.
Tilt the steering wheel to the highest position to give
more room when exiting and entering the vehicle.
Turn Signal/Multifunction Lever
The 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
3-5

Turn and Lane-Change Signals
To signal a turn, move the 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 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 5-52andTaillamps, Turn Signal, and
Stoplamps on page 5-54for turn signal bulb replacement
procedures. Also seeFuses and Circuit Breakers on
page 5-97for 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.

You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to readjust 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 can not 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.
