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

Turn Signal and Lane Change Signals

Headlamp High/Low
-Beam Changer

Flash
-To-Pass Feature

Windshield Wipers

Windshield Washer
For more information on exterior lamps, see ªExterior
Lampsº later in this section.
Turn Signal and Lane Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow on the instrument
panel cluster will flash in
the direction of the turn or
lane change.
If your vehicle is equipped with the Head
-Up Display
(HUD), an arrow will also appear in the display area
to indicate the direction of the turn or lane change.
See ªHead
-Up Display (HUD)º in the Index for
more information.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. The lever will return by itself when you
release it.
If the arrows flash very fast 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.

2-37
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 the fuse (see ªFuses and Circuit
Breakersº in the Index) and for burned
-out bulbs.
Turn Signal On Chime
If your turn signal is left on for more than 0.8 miles
(1.3 km), a chime will sound at each flash of the turn
signal. To turn off the chime, move the turn signal lever
to the off position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam
or high beam to low beam, pull the turn signal lever
toward you and release it.
When the high beams are
on, this light located on the
instrument panel cluster will
also be on.If your vehicle is equipped with the Head
-Up Display
(HUD), an arrow will also appear in the display area to
indicate the high beams are on (See ªHead
-Up Display
(HUD)º in Index for more information).
Flash-To-Pass Feature
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
It works even if your headlamps are off.
Pull the turn signal lever toward you briefly to
flash
-to-pass.
If the headlamps are off or on low beam, the 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 instrument panel cluster comes on. Release the
lever to turn the high
-beam headlamps off.

4-39
When towing a trailer, the arrows on your instrument
panel will flash 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's important
to check occasionally to be sure the trailer bulbs are
still working.
Your vehicle has bulb warning lights. When you plug
a trailer lighting system into your vehicle's lighting
system, its bulb warning lights may not let you know
if one of your lamps goes out. So, when you have a
trailer lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they're all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell you if
one of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gear before you
start down a long or steep downgrade. If you don't
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 to THIRD (3) and
reduce your speed to around 45 mph (70 km/h) to reduce
the possibility of engine and transaxle overheating.
Parking on Hills
CAUTION:
You really should not park your vehicle, with
a trailer attached, on a hill. If something goes
wrong, your rig could start to move. People can
be injured, and both your vehicle and the trailer
can be damaged.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but don't shift into
PARK (P) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK (P).
5. Release the regular brakes.
