Press the wiper switch to the desired
position1,2 or3, depending on
the intensity of the rain.
Single wipe

Press wiper switch briefly in the direc-
tion of arrow2.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid

Pull and hold wiper switch in direction
of arrow4.
The windshield wiper operates with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system*”
(
page 230).
!Vehicles with rain sensor*:
Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and / or damage the wiper blades
when wiping occurs on a dry wind-
shield.

156 Controls in detailDriving systemsParktronic* system (Parking assist)
The Parktronic system is an electronic and
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically
activated when you switch on the ignition.
The Parktronic system deactivates at
speeds over approximately 10 mph
(15 km / h). At lower speeds the Parktronic
system turns on again.The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors located in front bumperWarning!
G
The Parktronic is a supplemental system. It
is not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Parktronic system sensors”
(page 243).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash,
or the air brakes of trucks) can cause the
system to send erratic indications, and
should be taken into consideration.
Warning!
G
Make sure that no persons or animals are in
the area in which you are maneuvering. You
could otherwise injure them.

Range of the sensors
To function properly, the sensors must be
free of dirt, ice, snow and slush. Clean the
sensors regularly, being careful not to
scratch or damaging the sensors.Front sensors
Rear sensorsMinimum distance
When an obstacle is located in this area, all
warning displays will light up and a warning
tone will sound. If the vehicle moves closer
than the minimum distance to an object,
the distance may no longer be displayed.

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Park-
tronic system will not detect such ob-
jects at close range and damage to
your vehicle or the object may result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Parktronic system.

The warning indicators show the distance
between the sensor and the obstacle. The
warning indicators for the front area are lo-
cated above the center air vents in the
dashboard. The warning indicator for the
rear area is located in the rear passenger
compartment lamp.Front area warning indicator1Segments, left side of vehicle
2Segments, right side of vehicle
Each warning indicator has six yellow and
two red segments.The gear selector lever position deter-
mines which warning indicator is activat-
ed.
As soon as the sensors detect an obstacle,
one or more segments light up, depending
on the distance. An intermittent acoustic
warning will also sound as the seventh seg-
ment comes on and a constant acoustic
warning lasting a maximum of
three seconds will sound for the eighth
segment.

!If all red segments light up in the warn-

After cleaning the sensors, switch
the ignition on.
