Windshield wipers
Switching the windshield wipers
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, alwaysu se
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.

XTurn the combination switch to the corre-

!Vehicles with arain sensor: if the windshield
becomes dirty in dry weather conditions, the
windshield wipers may be activated inadver-
tently. This could then damage the windshield
wiper blades or scratch the windshield.
For this reason, you should alwayss witch off
the windshield wipers in dry weather.
Vehicles with arain sensor: in the ÄorÅ
position, the appropriate wiping frequency is
automatically set accordingtot he intensity of
the rain. In the Åposition, the rain sensor is
more sensitive than in the Äposition, caus-
ing the windshield wiper to wipe more fre-
quently.
If the wiper blades are worn, the windshield will
no longer be wiped properly. This could prevent
you from observing the traffic conditions.

Start/Stop button
General notes
Vehicles with KEYLESS-GO are equipped with
SmartKeys featuring the integrated KEYLESS-
GO function and adetachable Start/Stop but-
ton.
Ac heck which periodically establishes aradio
connection between the vehicle and the Smart-
Key determines whether avalid SmartKey is in
the vehicle. This occurs, for example, when
starting the engine.
When you insert the Start/Stop button into the
ignition lock, the system needs approximately
two seconds recognition time. You can then use
the Start/Stop button.
Pressing the Start/Stop button several times in
succession corresponds to the different Smart-
Key positions in the ignition lock. This is only the
case if you are not depressing the brake pedal.
If you depress the brake pedal and press the
Start/Stop button, the engine starts immedi-
ately.
To start the vehicle without actively using the
SmartKey:
Rthe Start/Stop button must be inserted in the
ignition lock
Rthe SmartKey must be in the vehicle
Rthe vehicle must not be locked with the
SmartKey or KEYLESS-GO (Ypage 71)
Do not keep the KEYLESS-GO key:
Rwith electronic devices, e.g. amobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. ametal case.
This can affect the functionality of KEYLESS-GO.
If you lock the vehicle with the SmartKey remote
control or with KEYLESS-GO, after ashort time:
Ryou will not be able to switch on the ignition
with the Start/Stop button.
Ryou will no longer be able to start the engine
with the Start/Stop button until the vehicle is
unlocked again.
If you lock the vehicle centrally using the button
on the front door (
Ypage 76), you can continue
to start the engine with the Start/Stop button.
The engine can be switched off while the vehicle
is in motion by pressing and holding the Start/
Stop button for three seconds. This function
