vehicle
The braking e"Mect is reduced a"ser washing
the vehicle.
A"ser the vehicle has been washed, brake
carefully while paying attention to the
tra"Pc conditions until the braking e"Mect
has been fully restored.*NOTE Damage from automatic braking
If one of the following functions is activated,
the vehicle will brake 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 situa-
tions:
During towing.In a car wash.*NOTE Damage due to unsuitable car washBefore driving into a car wash make sure
that the car wash is suitable for the vehi-
cle dimensions.322Maintenance and care

Ensure there is su"Pcient ground clear-
ance 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 su"Pcient.
To avoid damage to your vehicle when using a car
wash, ensure the following beforehand:
= Active Distance Assist DISTRONIC is deactiva-
ted.

cleaning before parking it. The brake discs and pads will warm up and dry out.
Windows*NOTE Damage to electronic components
due to excess "Ouids
When cleaning the windows from the inside,
"Ouids such as cleaning agents or water may
run down and get behind trim parts of the
vehicle interior and cause damage to elec- tronic components.
Use cleaning agents as sparingly as pos-sible.Immediately absorb any excess "Ouids.
