|:Press 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.
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn.
An arrow on the instrument 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. If the lever is
moved momentarily to the lane
change position, the arrow will flash
three times.
The lever returns to its starting
position when it is released.
If after signaling a turn or lane
change, the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Have any burned out bulbs
replaced. If a bulb is not burned out,
check the fuse. See
Instrument
Panel Fuse Block 0296.
Fog Lamps
The fog lamps button is on the
instrument panel beside the steering
wheel.
To turn on the fog lamps, the ignition
and the headlamps or parking lamps
must be on.
#:If equipped, press to turn on or
off. An indicator light on the
instrument cluster comes on when
the fog lamps are on.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.

Driving and Operating 253
Caution (Continued)
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 in 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 turn
signal indicators in 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.
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.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes beforeturning the engine off. If the
overheat warning comes on, see
Engine Overheating
0280.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill.
2. Have someone place chocks under the trailer wheels.
