High Beam
NOTE: The headlights must be “ON” for the high
beam switch to operate.
•To switch your headlights to lower or higher beam,
push and release the button on the end of the turn signal
stalk. The blue indicator light in the instrument panel will
be ON when the high beam is being used.
• To return to previous beam: push and release the button
again.
Emergency Flasher Switch
The four-way Emergency Flasher switch is on the turn signal
body, just below the turn signal lever. The emergency flasher
makes all four turn signals (front and rear) flash simulta-
neously. The flasher works independently of the ignition
switch. You should always use the flasher if the vehicle is dis-
abled or parked under emergency conditions.
• To operate the emergency flasher, pull the lever out.
• The flasher is self-cancelling. To turn it off, activate the
left or right turn signal.
WARNING! Use your Hazard Flasher Warning
System any time you have to stop off the road or
on the side of the road, day or night. A hard-to-
see vehicle can result in an injury accident.
Another vehicle could run into you if you do not
set your flashers. Always move the vehicle a
safe distance off the road when stalled or
stopped for repairs.
• Your disabled vehicle can be dangerous for you and
others. The hot exhaust system could ignite dry
grass, brush, spilled fuel, or other material that can
cause fires. Do not park or operate your vehicle in
areas where the hot exhaust system could cause a
fire.
Trailer Brake Hand Valve
This hand valve, mounted on the steering wheel column of
tractor/trailer vehicles, provides air pressure to apply the
trailer brakes only. It operates independently of the foot trea-
dle valve. See
page 81
for more instructions on proper use of
the Trailer Brake Hand Valve.
