Windshield wipers
Switching the windshield wipers
on/off
!Do not operate the windshield wiperswhen the windshield is dry, as this coulddamage the wiper blades. Moreover, dustthat has collected on the windshield canscratch the glass if wiping takes place whenthe windshield is dry.
If it is necessary to switch on the windshieldwipers in dry weather conditions, always usewasher fluid when operating the windshieldwipers.
!If the windshield wipers leave smears onthe windshield after the vehicle has beenwashed in an automatic car wash, wax orother residues may be the reason for this.Clean the windshield using washer fluidafter washing the vehicle in an automaticcar wash.
!Intermittent wiping with rain sensor: dueto optical influences and the windshieldbecoming dirty in dry weather conditions,the windshield wipers may be activatedinadvertently. This could then damage thewindshield wiper blades or scratch the wind-shield.
For this reason, you should always switchoff the windshield wipers in dry weather.

!Never open the hood if a windshield wiperarm has been folded away from the wind-shield.
Never fold a windshield wiper arm without awiper blade back onto the windshield.

!Do not park your vehicle for a long periodof time directly after cleaning, particularlyafter cleaning the wheel rim with wheelcleaner. Wheel cleaner can lead to theincreased corrosion of the brake discs andpads. Therefore, drive for a few minutesafter cleaning. By heating up the brakes, thebrake discs and pads dry. The vehicle canthen be parked for a long period of time.
Regular care of your vehicle is a condition forretaining the quality in the long term.

Washing the vehicle and cleaning
the paintwork
Automatic car wash
GWARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is
restored.
!When DISTRONIC PLUS or the HOLD func-tion is activated, the vehicle brakes auto-matically in certain situations.
To avoid damage to the vehicle, deactivateDISTRONIC PLUS and the HOLD function inthe following or similar situations:
Rwhen towing the vehicle
Rin the car wash
!It is preferable to use car washes withadjustable high-pressure pre-cleaning thatcorresponds to the specification for theCabriolet program. In car washes that usehigh water pressures, there is a risk that asmall amount of water may leak into thevehicle.
!Lock the car if you wash it in an automaticcar wash. Otherwise, the vehicle might bedamaged.
!Never clean your vehicle in a TouchlessAutomatic Car Wash as these use specialcleaning agents. These cleaning agents candamage the paintwork or plastic parts.
If you have your vehicle cleaned in a high-pressure automatic car wash, smallamounts of water may enter the vehicle.
!Make sure that the automatic transmissionis in positionNwhen washing your vehiclein a tow-through car wash. The vehicle couldbe damaged if the transmission is in anotherposition.
!Make sure that:
Rthe side windows and the roof are com-pletely closed
Rthe climate control blower is switched off
Rthe windshield wiper switch is at position0
The vehicle could otherwise be damaged.
You can clean the vehicle at an automatic carwash from the very start.
Preferably clean the vehicle at automatic carwashes that use textile washing elementswithout brushes. This prevents fine scratchesfrom forming on the paintwork and film.
If the vehicle is very dirty, pre-wash it beforecleaning it in an automatic car wash.
After using an automatic car wash, wipe offwax from the windshield and the wiper blades.This will prevent smears and reduce wipingnoises caused by residue on the windshield.
iVehicles with decorative film: select awash program without hot wax at the auto-matic car wash.
Washing by hand
