Operation Vehicle care ! Do not apply strong pressure to the sensor covers. Applying strong pressure may damage the sensor covers. Follow the instructions provided by the power washer manufacturer on maintaining a distance between the vehicle and the nozzle of the power washer. Cleaning the windows and the wiper blades Clean the wiper blade inserts with a clean cloth and detergent solution. Use a soft, clean cloth and a mild window cleaning solution on all outside and inside glass surfaces. An automotive glass cleaner is recommended. ! Never open the hood when the wiper arms are folded forward. Make sure the hood is fully closed. Make sure the vehicle's on-board electronics have status 0 ( page 38). Warning! ! To prevent scratches, never apply strong force and only use a soft, non-scratching cloth when cleaning the sensors. Do not attempt to wipe dirty sensors with a dry cloth or sponge. G For safety reasons, switch off wipers and remove SmartKey from starter switch (vehicles with KEYLESS-GO*: Make sure the vehicle's on-board electronics have status 0) before cleaning the windshield and/or the wiper blades. Otherwise, the wiper motor could suddenly turn on and cause injury. ! Fold the windshield wiper arms back onto the windshield before turning the SmartKey in the starter switch or pressing the KEYLESS-GO start/stop button (vehicles with KEYLESS-GO*). Hold on to the wiper when folding the wiper arm back. If released, the force of the impact from the tensioning spring could crack the windshield. ! To clean the window interior, do not use a dry cloth, abrasives, solvents or cleaners containing solvents. Do not touch the inside of the front, rear or side windows with hard objects such as an ice scraper or ring. Doing so may damage the windows. Fold the wiper arms forward until they snap into place. ! Do not pull on the wiper blade inserts. They could tear. 373
