132 Controls in detailGood visibilityIntermittent wiping
Windshield wipers without rain sensor*
At speeds of approximately 105 mph
(170 km / h) the wiper switches automati-
cally to continuous wiping. Always obey lo-
cal speed limits.Windshield wipers with rain sensor*
A rain sensor automatically controls the
windshield wipers depending on how wet
the windshield is.

Switch on ignition.

Set the wiper switch to position1
(page 51).
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor which monitors the wetness of
windshield.
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a front
door is opened.
iWhen intermittent wiping is on and the
key is turned from position1 to
position2 in the steering lock
(page 33), and kept in that position
for longer than two seconds, the wipe
interval will be set to approximately
five seconds.
!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.

The button is located on the right side of
the dashboard.Headlamp washer button
Switch on ignition.

Briefly press the upper part of button.
The headlamps will be cleaned with a
high-pressure water jet.For information on filling up the washer
reservoir, see the “Operation” section
(
page 230).
Rear window wiper
For more information on Rear window wip-
er, see the “Getting started” section
(page 52).
The rear window wiper will also automati-
cally engage if the windshield wiper is en-
gaged and the gear selector lever is placed
in reverse.Rear window wiper with rain sensor*
Rear window wiper intervals are controlled
automatically according to the amount of
water on the windshield and the speed of
the vehicle, if:


rear window wiper is switched on


front windshield wipers are switched to
intermittent wiping
The interval for the rear window wiper re-
mains constant when the windshield wiper
interval is ten seconds or more.

138 Controls in detailAutomatic climate controlThe automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burns or frostbite on unprotected skin
in the immediate area of the air vents.
Always keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary, change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 140).
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A
clogged filter will reduce the air volume
to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not touch the interior temperature
sensor to maintain a precise tempera-
ture.
The set value is indicated by a lighted
segment on the control wheels.

If you press and hold the switch when clos-
ing the window, and upward movement of
the window is blocked by some obstruction
including but not limited to arms, hands, fin-
gers, etc., the automatic reversal will not op-
erate.
!If the upward movement of the window
is blocked during the closing proce-
dure, the window will stop and open
slightly.
Remove the obstruction, press the
switchj again past the resistance

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

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

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.
