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 Wipers
Use the intermittent wiper when weather
conditions make a single wiping cycle, with a
variable pause between cycles, desirable. Rotate
the end of the lever to the first detent position for
one of four intermittent settings. The delay cycle
can be set anywhere between 1 to 18 seconds.
NOTE:The wiper delay times depend on vehicle speed. If
the vehicle is moving less than 10 mph (16 km/h),
delay times will be doubled. Windshield Washers
To use the washer, pull the lever toward you and
hold until desired spray is reached. If the lever is
pulled while in the delay range, the wiper will start
and continue to operate for two or three wipe
cycles after the lever is released. Then, the
intermittent interval previously selected will
resume.
If the lever is pulled while in the off position, the
wipers will operate for two or three wipe cycles.
Then, the wipers will turn off.
NOTE:As a protective measure, the washer will stop if the
switch is held for more than 20 seconds. Once the
switch is released the washer will resume normal
operation.
Mist
Push upward on the wiper lever to activate a single
wipe to clear off-road mist or spray from a passing
vehicle. As long as the lever is held up, the wipers
will continue to operate.
NOTE:The mist feature does not activate the washer
pump; therefore, no washer fluid will be sprayed on
the windshield. The washer function must be used
in order to spray the windshield with washer fluid.
For information on wiper care and replacement,
see Ú
page 374.
CLIMATE CONTROLS
The Climate Control system allows you to regulate
the temperature, air flow, and direction of air
circulating throughout the vehicle. The controls are
located on the touchscreen and on the instrument
panel below the radio.
CAUTION!
In cold weather, always turn off the wiper switch
and allow the wipers to return to the park
position before turning off the engine. If the
wiper switch is left on and the wipers freeze to
the windshield, damage to the wiper motor may
occur when the vehicle is restarted.
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.

overheating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
