168 Lighting
Hazard Warning Flashers
|:Press this button to make the
front and rear turn signal lamps
flash on and off. This warns others
that you are having trouble. Press
again to turn the flashers off.
The turn signals do not work while
the hazard warning flashers are on.
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn.
An arrow on the instrument cluster
flashes 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 completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane-change signal
can be turned off manually by
moving the lever back to its original
position. If after signaling a turn or lane
change, the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Replace any burned out bulbs. If a
bulb is not burned out, check the
fuse. See
Fuses and Circuit
Breakers 0306.Fog Lamps
Use the fog lamps for better vision
in foggy or misty conditions.
#:Turn the band down and
release to turn the fog lamps on or
off. A light comes on in the
instrument cluster when the fog
lamps are in use. The ignition must
be on for the fog lamps to work.

272 Driving and Operating
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move your 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 TurnsCaution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees, or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument cluster flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes, or stopping. When towing a trailer, the arrows on
the instrument cluster flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
The Tow/Haul Mode may be used if
the transmission shifts too often.
See
Tow/Haul Mode 0232.
When towing at high altitude on
steep uphill grades, engine coolant
boils at a lower temperature than at
normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle could show
signs similar to engine overheating.
