Mercedes-Benz GLC : Cleaning and care / Notes on washing the vehicle in a car wash

WARNING Risk of accident due to reduced braking effect after washing the vehicle

The braking effect is reduced after washing the vehicle.

After the vehicle has been washed, brake carefully while paying attention to the traffic conditions until the braking effect has been fully restored.

NOTE Damage from automatic braking

If one of the following functions is switched on, the vehicle brakes automatically in certain situations:

• Active Brake Assist
• Active Distance Assist DISTRONIC
• HOLD function
• Active Parking Assist

To avoid damage to the vehicle, deactivate these systems in the following or similar situations:

During towing

In a car wash

NOTE Damage due to unsuitable car wash

Before driving into a car wash make sure that the car wash is suitable for the vehicle dimensions.

Ensure there is sufficient ground clearance between the underbody and the guide rails of the car wash.

Ensure that the clearance width of the car wash, in particular the width of the guide rails, is sufficient.

To avoid damage to your vehicle when using a car wash, ensure the following beforehand:

• Active Distance Assist DISTRONIC is deactivated.
• The HOLD function is switched off.
• The surround view camera or the rear view camera is switched off.
• The side windows and sliding sunroof are completely closed.
• The blower for the ventilation/heating is switched off.
• The windshield wiper switch is in position .
• The SmartKey is at a minimum distance of 10 ft (3 m) away from the vehicle. Otherwise the tailgate could open unintentionally.
• In automatic car washes with conveyor systems:
  • Neutral is engaged.
  • If you would like to leave the vehicle while it is being washed, make sure the Smart‐Key is located in the vehicle. The park position is otherwise automatically engaged.

If, after the car wash, you remove the wax from the windshield and wiper rubbers, this will prevent smearing and reduce wiper noise.
