Turn and Lane-Change Signals
The turn signal has two upward (for right) and
two downward (for left) positions. These positions
let you 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
returns automatically.
An arrow on the
instrument panel
cluster ashes 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 returns
by itself when released. The bottom of the outside
rearview mirrors might also have lane change
indicators.As you signal a turn or a lane change, if the
arrows ash more quickly than normal, a signal
bulb could 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 the fuse. SeeFuses
and Circuit Breakers on page 503and check for
burned-out bulbs.
If you have a trailer towing option with added
wiring for the trailer lamps, a turn signal asher
is used. With this asher installed, the signal
indicator ashes even if a turn signal bulb
is burned out. Check the front and rear turn signal
lamps regularly to make sure they are working.
Turn Signal On Chime
If your turn signal is left on for more than
3/4 of a mile (1.2 km), a chime sounds at each
ash of the turn signal. To turn off the chime,
move the turn signal lever to the off position.

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
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’s important to check occasionally to
be sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gearbefore
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.
You can tow in DRIVE (D). You may want to shift
the transmission to THIRD (3) or a lower gear,
under heavy loads or hilly conditions.
When towing at high altitude on steep uphill
grades, consider the following: Engine coolant will
boil at a lower temperature than at normal
altitudes. If you turn your engine off immediately
after towing at high altitude on steep uphill grades,
your vehicle may show signs similar to engine
overheating. To avoid this, let the engine run while
parked (preferably on level ground) with the
automatic transmission in PARK (P) for a few
minutes before turning the engine off. If you do get
the overheat warning, seeEngine Overheating
on page 418.
