Brake fluid
Visit workshop
There is insufficient brake fluid in the 
reservoir.
Risk of accident! Stop the vehicle in a 
safe location and notify an authorized 
Mercedes-Benz Center. Do not add 
brake fluid! This will not solve the 
problem.
Warning!
G
Driving with the messages “Brake fluid Visit 
workshop” displayed can result in an acci-
dent. Have your brake system checked im-
mediately.
If there is a malfunction in the 
electro-hydraulic brake system, we recom-
mend that the vehicle be transported with 
all wheels off the ground using flatbed or ap-
propriate wheel lift/dolly equipment.
A tow bar must be used if circumstances do 
not permit the use of the recommended 
towing methods and the vehicle requires 
towing with all four wheels on the ground.
Towing the vehicle with all four wheels on 
the ground is only permissible for distances 
up to 30 miles (50 km) and at a speed not to 
exceed 30 mph (50 km/h). For more infor-
mation, refer to “Towing the vehicle” 
(page 437).
If the electro-hydraulic brake system enters 
its emergency operation mode, the driver 
must apply significantly greater brake pedal 
pressure and depress the pedal much fur-
ther than normal to obtain braking effect. If 
necessary, apply full pressure to the brake 
pedal. Brakes may only be applied to the 
front wheels. Stopping distance is in-
creased!
Do not add brake fluid before checking the 
brake system. Overfilling the brake fluid res-
ervoir can result in spilling brake fluid on hot 
engine parts and the brake fluid catching 
fire. You can be seriously burned.!If you find that the brake fluid in the 
brake fluid reservoir has fallen to the 
minimum mark or below, have the 
brake system checked for brake pad 
thickness and leaks.
