Practical hints Replacing wiper blades Warning! G Warning! G ! To avoid damage to the hood, never open the hood when the wiper arm is folded forward. For safety reasons, switch off wipers and remove SmartKey from starter switch (vehicles with KEYLESS-GO* (Canada only): Make sure the vehicle's on-board electronics have status 0) before replacing a wiper blade. Otherwise, the wiper motor could suddenly turn on and cause injury. Wiper blades are components that are subject to wear and tear. Change the wiper blades twice a year, preferably in the spring and fall. Otherwise the windows will not be properly wiped. As a result, you may not be able to observe surrounding traffic conditions and could cause an accident. ! 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. Do not allow the wiper arms to contact the windshield glass without a wiper blade inserted. For your convenience, we recommend that you have this work carried out at an authorized Mercedes-Benz Center. 438
