Windshield wipers
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 col-
lected 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 resi-
dues may be the reason for this. Clean the
windshield using washer fluid after washing
the vehicle in an automatic car wash.
!Vehicles with rain/light sensor:
Switch the wipers off in dry weather. Other-
wise, dirt or optical effects may cause unde-
sired windshield wiper sweeps. This could
then damage the windshield wiper blades or
scratch the windshield.
The windshield will no longer be wiped properly
if the wiper blades are worn. Replace the wiper
blades twice a year (
Ypage 94), ideally in
spring and fall.
Combination switch
XTurn the key to position 1or 2in the ignition
lock.
XTurn the combination switch in the direction
of arrow ;to the appropriate setting
depending on the intensity of the rain.
XSingle wipe: push the combination switch
briefly to the pressure point in the direction of arrow :.
XTo wipe with washer fluid: press the com-
bination switch beyond the pressure point in
the direction of arrow :.
The detent positions of the combination switch
correspond to the following wiper speeds:
0W indshield wipers off

Rtrailer tow hitch for play and security
The trailer coupling is one of the most
important vehicle parts with regard to road
safety. The separate instructions issued by

care and maintenance should be observed.
Rthat contour markings on attachments and
bodies are in good condition
XRectify any noticeable defects before com-
mencing the journey.
Checks in the vehicle
Emergency equipment and first-aid kit

ment is in the front door stowage compartments
and behind the driver's seat.

Before driving off
GWARNING
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 footwell.
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.
GWARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
Rshoes with thick soles
Rshoes with high heels
Rslippers
There is a risk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals.
XSecure the load as per the loading guidelines
(Ypage 212).
XStow luggage items securely. Secure the load
