Turn 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 located on the
instrument panel cluster will
flash in the direction of the
turn or lane change.
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 returns when it is released.
If the turn signal is left on, a warning chime will sound
and the Driver Information Center (DIC) will display
TURN SIGNAL ON (after driving about a mile) to
remind you to turn it off.Arrows that flash rapidly when signaling for a turn or
lane change may be caused by a burned
-out signal bulb.
Other drivers won't see the turn signal.
Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse (see ªFuses and Circuit
Breakersº in the Index) and check for burned
-out bulbs
if the arrow fails to work when signaling a turn.
Headlamp High/Low-Beam Changer
When the low-beam headlamps are on, push the turn
signal lever away from you to change the headlamps to
high beam.
This light on the instrument
panel cluster will be on,
indicating high
-beam usage.
Pull the turn signal lever toward you to return to
low
-beam headlamps.

4-37 Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that
hand to the left. To move the trailer to the right, move
your hand to the right. Always back up slowly and,
if possible, have someone guide you.
Making Turns
NOTICE:
Making very sharp turns while trailering
could cause the trailer to come in contact with
the vehicle. Your vehicle could be damaged.
Avoid making very sharp turns while trailering.
When you're turning with a trailer, make wider turns than
normal. Do this so your trailer won't strike soft shoulders,
curbs, road signs, trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring.
Check with your dealer. The arrows on your
instrument panel will flash whenever you signal a
turn or lane change. Properly hooked up, the trailer
lamps will also flash, telling other drivers you're about
to turn, change lanes or stop.
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.
