If you have a trailer towing option with added wiring for
the trailer lamps, the signal indicator will flash at a
normal rate even if a turn signal bulb is burned
out. Check the front and rear turn signal lamps regularly
to make sure they are working.
Turn Signal On Chime
If either turn signal is left on for more than 3/4 mile
(1.2 km), a chime will sound to let the driver know to turn
it off.
If you need to leave the signal on for more than 3/4 mile
(1.2 km), turn
off
the signal and then turn it back on.
Headlamp High/Low-Beam Changer
To change the headlamps from high to low beam, or
low to high, simply pull the turn signal lever all the way
toward you. Then release it.
When the high beams are
on, this light on the
instrument panel cluster
will also be on.
Your fog lamps will turn
off
when you switch to high
beams. Using your high beams in fog is not
recommended.
Flash-to-Pass
When the headlamps are off, pull the lever toward you
to momentarily switch on the high beams (to signal
that you are going to pass). When you release the lever,
they will turn off.
Windshield Wipers
To operate the windshield wipers turn the band marked
WIPER, located on the multifunction lever.
MIST: Turn the band to MIST for a single wiping cycle.
Hold it there until the wipers start. Then let go. The
wipers will stop after one wipe. If you want more wipes,
hold the band on mist longer.
OFF: Turn the band to OFF to turn off the windshield
wipers.
LOW: Turn the band to LOW, for steady wiping at low
speed.
HIGH: Turn the band to HIGH, for steady wiping at high
speed.
