WINDSHIELD
WIPERS
Windshield Wipers
The windshield wiper stalk is located on
the right side of the steering wheel.
The windshield wipers will only operate
with the ignition turned ON.
Caution!
Turn the windshield wipers off when
driving through an automatic car wash.
Damage to the windshield wipers may
result if the wiper control is left in any
position other than off.
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.
Always remove any buildup of snow that
prevents the windshield wiper blades from
returning to the off position. If the
windshield wiper control is turned off and
the blades cannot return to the off position,
damage to the wiper motor may occur.
Windshield Wiper/
Washers
Operation: The switch on the wiper
stalk can be set to the following
positions:
Windshield Wiper Off.
Low Sensitivity Rain Sensing.

GETTING TO KNOW YOUR VEHICLE

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.
Rain Sensor
The Rain Sensor is located behind the
interior rear view mirror. This feature
senses moisture on the windshield and
automatically activates the wipers for
the driver.
The feature is especially useful for road
splash or over spray from the
windshield washers of the vehicle
ahead. Rotate the end of themultifunction lever to one of four
settings to activate this feature.
The sensor has an adjustment range
that varies progressively from wiper still
(no stroke) when the windshield is dry,
to wiper at continuous speed (fast
operation) with intense rain.
Activation
Rotating the wiper switch to position
oractivates the rain sensor.
The activation of the rain sensor system
is done by tapping the wiper stalk
upwards while the switch is in the
orposition.
The variation in sensitivity during rain
sensor operation is also signaled by a
stroke of the wiper (command acquired
and implemented). This stroke is also
executed with the windshield dry.
If the windshield washer is used with
the rain sensor activated, the normal
washing cycle is performed, after which
the rain sensor resumes its normal
automatic operation.
Note: Keep the glass in the sensor
area clean.
Deactivation
Use the wiper switch or turn the ignition
to STOP.
If the ignition is moved to the STOP
position and the wiper switch is left in
orposition, no wiping cycle will
occur even if it rains when the vehicle is
next started (ignition at ON). This prevents accidental activation of
the rain sensor when the engine is
started (e.g. when the windshield is
being washed by hand or the wipers
are stuck to the windshield by ice).
You can restore the automatic
functioning of the rain sensor by lifting
the windshield wiper control (anti-panic
function).
When the rain sensor is reactivated
using any of the functions described
above, reactivation is indicated by a
single tap of the windshield wipers,
regardless of the condition of the
windshield.
In the event of malfunction of the rain
sensor while it is active, the windshield
wiper operates intermittently at a speed
consistent with the sensitivity setting of
the rain sensor, whether there is rain on
the glass, while the sensor failure is
indicated on the display.
The sensor continues to operate and it
is possible to set the windshield wiper
to continuous mode
or.The
failure indication remains for as long as
the sensor is active.
The rain sensor is able to recognize and
automatically adjust itself in the
presence of the following conditions:
Presence of dirt on the controlled
surface (e.g. salt, dirt, etc.).
Presence of streaks of water caused
by the worn window wiper blades.
Difference between day and night.

The engagement of the recirculation
system makes it possible to reach the
required heating or cooling conditions
faster. It is, however, inadvisable to use
it on rainy/cold days as it can increase
the possibility of the windows fogging.
