Operation Vehicle care Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot. Use the appropriate MB-Touch-Up Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors, etc.). Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical components and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticorrosion Wax, should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bushings and joints should be lubricated. The poly-V-belt and all pulleys should be protected from any wax. Vehicle washing In the winter, thoroughly remove all traces of road salt as soon as possible. When washing the vehicle underbody, do not forget to clean the inner sides of the wheels. Thoroughly spray the vehicle with a diffused jet of water. Direct only a very weak spray towards the ventilation intake. Use plenty of water and rinse the sponge and chamois frequently. Rinse with clean water and thoroughly dry with a chamois. Do not allow cleaning agents to dry on the finish. i Vehicles with KEYLESS-GO*: If a door handle is hit by a strong jet of water, and a SmartKey with KEYLESS-GO* is in close proximity, i.e. within approximately 3 ft (approximately 1 m), the vehicle could be inadvertently locked or unlocked. Hand-wash Do not use hot water or wash your vehicle in direct sunlight. Only use a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo. ! Do not use scouring agents on these parts. Never apply strong force and only use a soft, non-sratching cloth when cleaning the vehicle. Do not attempt to wipe the surface with a dry cloth or sponge. Otherwise you may scratch or damage the paint. 427
