!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.

iThe SmartKey can be turned in the ignitionlock even if it is not the correct SmartKeyfor the vehicle. The ignition is not switchedon. The engine cannot be started.
KEYLESS-GO
General notes
Vehicles with KEYLESS-GO are equipped witha SmartKey featuring an integrated KEYLESS-GO start function and a detachable Start/Stopbutton.
The Start/Stop button must be inserted in theignition lock and the SmartKey must be in thevehicle.
When you insert the Start/Stop button intothe ignition lock, the system needs approx-imately two seconds recognition time. You canthen use the Start/Stop button.
Pressing the Start/Stop button several timesin succession corresponds to the different key
positions in the ignition lock. This is only thecase if you are not depressing the brake pedal.
If you depress the brake pedal and press theStart/Stop button, the engine starts immedi-ately.
A check which periodically establishes a radioconnection between the vehicle and theSmartKey determines whether a valid Smart-Key is in the vehicle. This occurs, for example,when starting the engine.
To start the vehicle without actively using theSmartKey:
Rthe Start/Stop button must be inserted inthe ignition lock.
Rthe SmartKey must be in the vehicle.
Rthe vehicle must not be locked with theSmartKey or KEYLESS-GO (Ypage 66).
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile phoneor another SmartKey.
Rwith metallic objects, e.g. coins or metalfoil.
Rinside metallic objects, e.g. a metal case.
This can impair the functionality of the KEY-LESS-GO key.
If you lock the vehicle with the SmartKey'sremote control or with KEYLESS-GO, after ashort time:
Ryou will not be able to switch on the ignitionwith the Start/Stop button.
Ryou will not be able to start the engine withthe Start/Stop button until the vehicle isunlocked again.
The engine can be switched off while the vehi-cle is in motion by pressing and holding theStart/Stop button for three seconds. Thisfunction operates independently of the ECOstart/stop automatic engine switch-off func-tion.
