Braking efficiency is reduced after washing the vehicle. This could cause an accident. For this reason, you must drive particularly carefully after washing the vehicle until the brakes have dried. Maintenance and care You can wash the vehicle in an automatic car wash from the very start. ! Never clean your vehicle in a Touchless Automatic Car Wash as these use special cleaning agents. These cleaning agents can damage the paintwork or plastic parts. If the vehicle is very dirty, pre-wash it before cleaning it in an automatic car wash. ! In car washes with a towing mechanism, make sure that the automatic transmission is in transmission position N, otherwise the vehicle could be damaged. ! Make sure that the side windows are completely closed, that the ventilation/ heating is switched off and that the windshield wiper switch is set to 0. Otherwise, the rain/light sensor could be activated, triggering unintended wiper movements. This can cause damage to the vehicle. After using an automatic car wash, wipe off wax from the windshield and the wiper blades. This will prevent smears and reduce wiping noises caused by residue on the windshield. Washing by hand Carefully remove all deposits of road salt as soon as possible when driving in winter. Power washers G Warning! Do not use power washers with circular-jet nozzles (dirt grinders) to clean your vehicle, in particular the tires. You could otherwise damage the tires and cause an accident. ! Keep the distance between the vehicle and the nozzle of the power washer at 11.8 in (30 cm). Information about the correct distance is available from the equipment manufacturer. Move the power washer nozzle around when cleaning your vehicle. Do not aim directly at any of the following: Rtires Rdoor joint Relectrical components Rbattery Rconnectors Rlights Rseals Rtrim elements Rventilation slots
