MAINTENANCE AND SERVICE Wiper blades If the rubber is found to be hardened or cracked, or if the wiper leaves a scratch on the windscreen or cannot clean a certain area, the wiper blade needs to be replaced. The service position can be used in the following situations: VESPER ■ Changing or cleaning the wiper blades. ■ Cleaning the windscreen. ■ Prevent the wiper blades from freezing onto the windscreen. If the wiper or windshield is covered or frozen by ice and snow, clean the ice and snow on the wiper and windshield before use the wiper, to avoid damaging the wiper.
Wipers shall not be used when the windshield is dry or with hard object on the surface, otherwise the wiper blades and windscreen may be damaged. Caution! ■ Oil, silicon and petroleum products tend to weaken the wiping effect of the wiper blades. Clean the wiper blades in warm soapy water and check their status regularly. ■ Use only wiper blades of the same specifications as the original ones. Before replacing the wiper blades, make sure the wiper blades are in the service position.
Activating/deactivating the service position When the vehicle is stationary and the windshield wiper is off, quickly move the wiper paddle down to the single wiping position for about 2 s after turning off the ignition to enable the wiper service position. When the front windshield wiper/washer function is activated, the wiper blade returns to its original position. Caution! If the wiper arms in service position have been folded up from the windscreen, they must be folded back onto the windscreen before the wipers are allowed to return to their original position. Otherwise, hood paint and wiper damage may occur. Caution!
Before selecting the service position, make sure the wiper blades are not frozen to the windscreen. 259
