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. This will
signal that you are going to pass. When you release the
lever, they will turn off.
Windshield Wipers
WIPER: Turn this band to operate the windshield
wipers.
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.
When the high beams are
on, this light on the
instrument panel cluster
will also be on.
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.
DELAY: Turn the band away from you to one of the
five sensitivity settings between OFF and LOW, to
choose the delayed wiping cycle. The further the band
is turned toward LOW, the shorter the delay will be.
Use this setting for light rain or snow.
Remember that damaged wiper blades may prevent you
from seeing well enough to drive safely. To avoid
damage, be sure to clear ice and snow from the wiper
blades before using them. If they're frozen to the
windshield, carefully loosen or thaw them. If your blades
do become damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. A circuit
breaker will stop them until the motor cools. Clear away
snow or ice to prevent an overload.
