WINDSHIELD WIPERS AND WASHERS
WINDSHIELD WIPERS
The wipers and washers are operated by a
switch in the multifunction lever, and can only
be operated with the ignition in the ACC or ON/
RUN position. Turn the end of the lever to select
the desired wiper speed.

Windshield Wiper/Washer Switch

Rotate the end of the lever upward, to the first
detent past the intermittent settings for
low-speed wiper operation. Rotate the end of the lever upward to the second detent past the
intermittent settings for high-speed wiper
operation.
Intermittent Wiper System
The intermittent feature of this system was
designed for use when weather conditions
make a single wiping cycle, with a variable
pause between cycles, desirable. For maximum
delay between cycles, rotate the control knob
upward to the first detent.
The delay interval decreases as you rotate the
knob until it enters the low continual speed
position. The delay can be regulated from a
maximum of about 18 seconds between cycles,
to a cycle every one second. The delay intervals
will double in duration when the vehicle speed
is 10 mph (16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer
knob, located on the end of the multifunction
lever, inward to the second detent. Washer fluid
will be sprayed and the wiper will operate for
two to three cycles after the washer knob is
released from this position.
If the washer knob is depressed while in the
delay range, the wiper will operate for several
seconds after the washer knob is released. It
will then resume the intermittent interval
previously selected. If the washer knob is
pushed while in the off position, the wiper will
turn on and cycle approximately three times
after the wash knob is released.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the temperature
range of your climate. This rating information
can be found on most washer fluid containers.
WARNING!
Sudden loss of visibility through the
windshield could lead to a collision. You might
not see other vehicles or other obstacles. To
avoid sudden icing of the windshield during
freezing weather, warm the windshield with
the defroster before and during windshield
washer use.

When the vehicle is turned off, be sure to
unplug any equipment as to not drain the
battery of the vehicle. All accessories connected
to the outlet(s) should be removed or turned off
when the vehicle is not in use to protect the
battery against discharge.
CAUTION!
Do not exceed the maximum power of
160 Watts (13 Amps) at 12 Volts. If the
160 Watts (13 Amps) power rating is
exceeded, the fuse protecting the system
will need to be replaced.

Power outlets are designed for accessory
plugs only. Do not insert any other object in
the power outlets as this will damage the
outlet and blow the fuse. Improper use of the
power outlet can cause damage not covered
by your New Vehicle Limited Warranty.

WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the
vehicle's battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.), will
discharge the battery even more quickly.
Only use these intermittently and with
greater caution.
After the use of high power draw accesso -
ries, or long periods of the vehicle not being
started (with accessories still plugged in),
the vehicle must be driven a sufficient
length of time to allow the generator to
recharge the vehicle's battery.
