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.
High Sensitivity Rain Sensing.
Low Continuous Wiper Speed.
High Continuous Wiper Speed.
Windshield Wiper Operation
Rotating the switch to the
position
activates the first (low) level continuous
speed of the windshield wipers in
manual mode.
Rotating the switch to the
position
activates the second (high) level
continuous speed of the windshield
wipers in manual mode. Rain Sensors
Rotating the switch to the
position,
activates the first, less sensitive level of
the Rain Sensing function.
Rotating the switch to theposition,activates the second, more sensitive level
of the Rain Sensing function. Refer to
“Rain Sensor” in this section for more
information on how this system functions.
Windshield Washer Operation
Pull the stalk toward the steering wheel
to operate the windshield washer.
Keep the stalk pulled to activate both the
windshield washer jet and the windshield
wiper with a single movement. The
wipers and washers will continue to
operate until you let go of the stalk.
The windshield wiper stops working
three strokes after the stalk is released,
followed by a final stroke six seconds
later to complete the cycle.
Mist
Use this feature when weather
conditions make occasional usage of
the wipers necessary. Push the stalk
upward to the MIST position and
release for a single wiping cycle. This
function is useful to remove small
deposits of dust from the windshield or
morning dew.
Note:
This function does not activate
the windshield washer. To spray
windshield washer fluid onto the
windshield, the washing function must be
used.

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.

GETTING TO KNOW YOUR VEHICLE

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.
When the outside temperature is low,
recirculation is forced off to prevent the
windows from fogging up.
A/C Compressor
Push the A/C buttonto activate or
deactivate the A/C compressor
(indicator illuminated when activated).
The A/C compressor will remain off
even after the engine has stopped.
When the A/C compressor is turned off,
the system deactivates air recirculation
to prevent the windows from fogging
up. If the climate control system can
maintain the temperature, with the A/C
turned off, the AUTO feature will remain
on and the AUTO button indicator light
will not switch off.
To restore automatic control of the A/C
compressor, push the A/C button
or
the AUTO button. With the A/C
compressor off, the air speed can be
set manually using the Air Speed
Adjustment Knob.
When the A/C compressor is on, and
the engine is running, air speed cannot
be lower than the minimum speed (only
one indicator light is lit). Note:
When the A/C is off the Climate
Control system can not produce air that
is colder than the current outside
temperature. Under certain
environmental conditions, windows
could fog up rapidly, since the air is not
dehumidified.
Front Defroster And
MAX-DEF Function
Push the Front Defroster button(indicator illuminated) to defrost the
windshield and side windows.
While in MAX-DEF function, the air
conditioner will:
Activate the air conditioner

Switching On The Climate Control
System
To switch the climate control system on
in automatic mode, push the AUTO
button.
Stop/Start Evo
The climate control system manages
the Stop/Start Evo system. Stop/Start
Evo has the engine shut off when
vehicle speed is 0 mph (0 km/h) to
maintain comfort within the vehicle.
Stop/Start Evo will deactivate in the
following scenarios:
The climate control system is in
AUTO mode (indicator illuminated), and
the vehicle has yet to reach the set
temperature
The LO setting is active
MAX-DEF status is active
When the Stop/Start Evo system is
active, the engine will restart if the
inside temperature changes
significantly, or if the LO setting, or
MAX-DEF setting, is activated.
With Stop/Start Evo system on, air flow
is reduced to keep the compartment
comfort conditions for longer.
Until the temperature drastically
changes within the cabin, the climate
control system will continue to maintain
the temperature while the engine is off.
By deactivating the Stop/Start Evo
system with the
button located on
the dashboard, the climate control
system will take priority over the engine
shutting off. Note:
In harsh climate conditions, limit the
use of the Stop/Start Evo system to
prevent the compressor from
continuously switching on and off. This
will cause rapid misting of the windows
and the accumulation of humidity in
the passenger compartment.
When the Stop/Start Evo system is
on, the climate control system will
always take air in from outside,
reducing the probability of the windows
fogging up.
Additional Heater — If
Equipped
Note:
The additional heater automatically
operates if the outside temperature and
engine coolant temperature are low.
The heater will not operate if battery
voltage is low.
System Maintenance
In winter, the Climate Control System
must be turned on at least once a
month for approximately 10 minutes.
Have the system inspected at an
authorized dealer before the summer.
