Turn and Lane-Change Signals
An arrow on the instrument
panel cluster will flash in
the direction of the turn or
lane change.
Move the lever all the way up or down to signal a turn.
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 lever returns to its starting position whenever it is
released.
If after signaling a turn or lane change the arrow flashes
rapidly or does not come on, a signal bulb might be
burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. SeeFuses and Circuit Breakers on
page 6-96

Turn Signals When Towing a TrailerThe arrows on the instrument panel 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
panel flash for turns even if the bulbs on the trailer are
burned out. For this reason you may think other
drivers are seeing the signal when they are not. It is
important to check occasionally to be sure the
trailer bulbs are still working.Driving on GradesNotice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher
than normal engine and transmission temperatures
may result and damage the vehicle. Frequent
stops are very important to allow the engine and
transmission to cool.
Reduce speed and shift to a lower gearbeforestarting
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.
On a long uphill grade, shift down and reduce the
vehicle’s speed to around 45 mph (70 km/h) to reduce
the possibility of the engine and the transmission
overheating. If the engine does overheat, seeEngine
Overheating on page 6-29.
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.
3. When the wheel chocks are in place, release the
brake pedal until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking
brake and shift the transmission into P (Park).
5. Release the brake pedal.
