Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
G: Turn and Lane Change Signals
53: Headlamp High/Low-Beam Changer
N: Windshield Wipers
L: Windshield Washer
Flash-to-Pass Feature
Information for these features is on the pages following.
Turn and Lane-Change Signals
An arrow on the instrument
panel cluster ashes 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 ash to
signal a lane change. The turn signals automatically ash
three times. It will ash six times if the tow-haul mode is
active. Holding the turn signal lever for more than one
second causes the turn signals to ash until the lever
is released.
The lever returns to its starting position when it is
released.
If after signaling a turn or a lane change the arrows
ash rapidly or do not come on, a signal bulb may be
burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. SeeInstrument Panel Fuse Block on
page 5-111andUnderhood Fuse Block on page 5-113.

Making Turns
Notice: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. Do this so the trailer will not 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 the instrument panel ash whenever
signaling a turn or lane change. Properly hooked up, the
trailer lamps also ash, telling other drivers the vehicle
is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument panel
ash 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 Grades
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.
Vehicles can tow in D (Drive). Shift the transmission to
a lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
The tow/haul mode may be used if the transmission
shifts too often. SeeTow/Haul Mode Light on page 3-44.
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 the engine is
turned off immediately after towing at high altitude on
steep uphill grades, the 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 P (Park) for a few minutes before turning
the engine off. If the overheat warning comes on, see
Engine Overheating on page 5-33.
