Turn Signal/Multifunction Lever
Turn and Lane Change Signals
To signal a turn, move the lever on the left side of the
steering wheel all the way up or down. The lever returns
automatically when the turn is complete.
An arrow located on the
instrument panel 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. 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 flash rapidly when signaling for a turn or
lane change may be caused by a burned
-out signal bulb.
Other drivers won't see the turn signal.
Replace burned
-out bulbs to help avoid possible
accidents. Check the fuse (see ªFuses and Circuit
Breakersº in the Index) and check for burned
-out
bulbs if the arrow fails to work when signaling a turn.
Headlamp High/Low Beam
When the low-beam headlamps are on, push the turn
signal lever away from you to change the headlamps to
high beam.
This light on the
instrument panel cluster
will be on, indicating
high
-beam usage.
Pull the turn signal lever toward you to return to
low
-beam headlamps.

4-37 Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a different
turn signal flasher and/or extra wiring. Check with your
dealer. The arrows on your instrument panel will flash
whenever you signal a turn or lane change. Properly
hooked up, the trailer lamps will also flash, telling other
drivers you're about to turn, change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will flash 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 gear before 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.
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 90F (32C) with a loaded vehicle and trailer is
not recommended. The cooling system may temporarily
overheat. See ªEngine Overheatingº in the Index.
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.
But if you ever have to park your rig on a hill, here's
how to do it:
1. Apply your regular brakes, but do not shift into
PARK (P).
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then shift into
PARK (P) firmly and apply your parking brake.
5. Release the regular brakes.
