activated when ªMixº or ªDefrostº modes are selected.
This is done to assist in drying the air and it will help in
keeping the windshield from fogging.
Operating Tips
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended.
Winter Operation
The air from the heater system will heat faster in cold
weather if you use lower blower speeds until the engine
warms up.
REAR WINDOW FEATURES Ð HARD TOP ONLY
Rear Window Defogger
To turn the rear window defogger on, press the
rocker switch. If you press the switch a second
time, you will turn the defogger off. A light on the rocker
switch will indicate the defogger is on.
The defogger will automatically turn off after about ten
minutes. For five more minutes of operation, depress the
top of the switch to turn the defogger on again. To
prevent excessive battery drain use the defogger only
when the engine is operating.

CAUTION!
Use care when washing the inside of the rear win-
dow to prevent damage to heating elements. Use a
soft cloth and a mild washing solution, wiping
parallel to the heating elements. Also, keep all
objects a safe distance from the window to prevent
damaging the heating elements.
Rear Window Wiper/Washer
To utilize the rear wiper, press the switch to the
first detent. To activate the rear washer, depress the
switch to the second detent. The washer will
continue to spray as long as the switch is held. The switch
will return to the wiper mode when released. To turn the
rear wiper off, lift the bottom of the switch.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
