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 nished, the lever will return
automatically.
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 you complete
your lane change. The lever will return by itself when
you release it. If you momentarily press and release the
lever, the turn signal will ash three times.
If the arrow ashes faster than normal as you signal a
turn or a lane change, a signal bulb may be burned
out and other drivers will not see your turn signal.

If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and then check
the fuse. SeeFuses and Circuit Breakers on
page 5-100.
Turn Signal On Chime
If either one of the turn signals are left on and you have
drove more than 3/4 mile (1.2 km), a chime will sound.
Headlamp High/Low-Beam
Changer
To change the headlamps from low beam to high beam,
push the turn signal/multifunction lever toward the
front of the vehicle.
This light on the instrument
panel cluster comes on
if the high beam lamps
are turned on while
the ignition is on.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward the rear of the vehicle.
Flash-to-Pass
With the turn signal lever in the low-beam position,
pull the lever toward you momentarily to switch
to high-beam, to signal that you are going to pass.
If the headlamps are on, they will return to low-beam
when the lever is released.
Windshield Wipers
Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield, gently
loosen or thaw them. Damaged wiper blades may
not clear the windshield well, making it harder to see
and drive safely. If the blades do become damaged,
install new blades or blade inserts. For more information,
seeWindshield Wiper Blade Replacement on page 5-47.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
Turn the band with the wiper symbol to control the
windshield wipers.

Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring. Check
with your dealer/retailer. The arrows on your instrument
panel will ash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
ash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It
is important to check occasionally to be sure the trailer
bulbs are still working.
Driving on Grades
Your vehicle is designed primarily as a passenger and
load carrying vehicle. If you tow a trailer, your vehicle
will require more frequent maintenance due to the
additional load. Because of the added load of the trailer,
your vehicle’s engine may overheat on hot days,
when going up a long or steep grade with a trailer. If the
engine coolant temperature gage indicates overheating,
turn off the air conditioning to reduce engine load,
pull off the road and stop in a safe spot.
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you do not shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
On a long uphill grade, shift down and reduce your
speed to around 55 mph (88 km/h) to reduce the
possibility of the engine and the transmission
overheating.
