Switching the windshield wiper
on/off
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield can
scratch the glass if wiping takes place when
the windshield is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always use
washer fluid when operating the windshield
wipers.
! If the windshield wipers leave smears on
the windshield after the vehicle has been
washed in an automatic car wash, wax or
other residues may be the reason for this.
Clean the windshield using washer fluid
after washing the vehicle in an automatic
car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windshield becoming dirty in dry weather conditions,
the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the wind-
shield.
For this reason, you should always switch
off the windshield wipers in dry weather. 1
$ Windshield wipers off
2 Ä Intermittent wipe, low (rain sensor
set to low sensitivity)
3 Å Intermittent wipe, high (rain sensor
set to high sensitivity)
4 ° Continuous wipe, slow
5 ¯ Continuous wipe, fast
B î 1st pressure point – single wipe; 2nd
pressure point – wipe with washer fluid
X Turn the key to position 1 or 2 in the igni-
tion lock.
X Turn the í wiper switch to the corre-
sponding position.
In the Ä or Å
positions, the appropriate
wiping frequency is set automatically accord-
ing to the intensity of the rain. In the Å
position, the rain sensor is more sensitive to
precipitation than in the Ä position, caus-
ing the windshield wipers to wipe more fre-
quently.
The windshield will no longer be wiped prop-
erly if the wiper blades are worn. This may pre-
vent you from observing the traffic conditions.
Information on replacing the wiper blades can
be found under "Replacing wiper blades"

tion, care and maintenance of the trailer
tow hitch (see the manufacturer's operat-
ing instructions).
X Rectify any noticeable defects before com-
mencing the journey. Checks in the vehicle Emergency equipment/first-aid kit

WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is
a risk of an accident.
Stow all objects securely in the vehicle so
that they do not get into the driver's foot-
well. When using floormats or carpets, make
sure that they are properly secured so that
they do not slip or obstruct the pedals. Do
not place several floormats or carpets on
top of one another. G
WARNING
Unsuitable footwear can hinder correct
usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. Driving
