Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster and in the
outside rearview mirror will
ash in the direction of
the turn or lane change.
Raise or lower the lever until the arrow starts to ash 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 ash rapidly when signaling for a turn or
lane change may be caused by a burned out signal bulb.
Other drivers will not see the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs
if the arrow fails to work when signaling a turn.
SeeRear Underseat Fuse Block on page 5-101.

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. 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 are 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
Reduce speed and shift to a lower gearbeforeyou 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 long uphill grades, reduce speed to 45 to 50 mph
(70 to 90 km/h) and avoid prolonged use of SECOND (2)
gear and engine speeds above 3800 rpm.Climbing grades steeper than four percent at
temperatures above 90°F (32°C) with a loaded vehicle
and trailer is not recommended. The cooling system
may temporarily overheat. SeeEngine Overheating on
page 5-27.
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.
