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.
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 the multifunction 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 cycle the ignition
to STOP.
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 or not there is
rain on the glass for as long as 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 on 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.

Forced deactivation (air recirculation
always off with intake of outside air):
both indicators not illuminated on the Air
Recirculation Button
The three operating conditions are
obtained by pushing the Air Recirculation
Button
in sequence. Enabling The Air Quality System (AQS)
Function — If Equipped
When the automatic recirculation
function is selected, the AQS function
automatically activates internal air
recirculation when the outside air is
polluted (e.g. in heavy traffic and tunnels).
At low external temperatures or in high
humidity, the automatic function turns
off to avoid fogging up the windows.
The user can select the function again by
pushing the Air Recirculation Button.
In
automatic operation, air recirculation
will be controlled by the system according
to outside environmental conditions.
Note:
With the AQS function active and
after the internal air recirculation
system has been functioning for a set
amount of time, the Climate Control
System enables air intake to cycle the
air in the passenger compartment for a
set time. The AQS function is disabled
during the air changes.
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.

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

GETTING TO KNOW YOUR VEHICLE

Note:The climate control system stores
the previously set temperatures and
resumes operation when any button on
the system is pushed.
Switching On The Climate Control
System
To switch the climate control system on
in automatic mode, push the AUTO
button.
Stop/Start
The climate control system manages the
Stop/Start system. Stop/Start has the
engine shut off when vehicle speed is
0 mph (0 km/h) to maintain comfort
within the vehicle.
Stop/Start 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 climate control system is in LO
maximum cooling
The climate control system is in HI
maximum heating
The climate control system is in the
MAX-DEF status
When the Stop/Start 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 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 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 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 system is on,
the climate control system will always
take air in from outside, reducing the
probability of the windows fogging up.
System Maintenance
In winter, the Climate Control System
must be turned on at least once a month
for approximately ten minutes.
Have the system inspected at an
authorized dealer before the summer.

The vehicle may be equipped with an
anti-pinch safety device for closing the
windows.
If the safety system senses any obstacle
while the window is closing, it will stop
the window’s movement and reverse it,
depending on its position.This device is also useful if the windows
are activated accidentally by children
inside the vehicle.
The anti-pinch safety function is
activated both during the manual and the
automatic operation of the window.
When the anti-pinch system is activated,
the window closing is immediately
interrupted. Then the window closing is
automatically reversed and the window
lowers by about eight inches (20 cm) in
relation to the first stop position. The
window cannot be operated during this
time.
