Power assistanceBrakesTo help prevent brake disk corrosion after 
driving on wet road surfaces (particularly 
salted roads), it is advisable to brake the 
vehicle with considerable force prior to 
parking. The heat generated serves to dry 
the brakes.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the 
brakes by applying above-normal braking 
pressure at higher speeds. This will also 
enhance the grip of the brake pads.If the parking brake is released and the 
brake warning lamp in the instrument clus-
ter stays on and there is no audible warn-
ing (EBB), the brake fluid level in the 
reservoir is too low.
Brake pad wear or a leak in the system may 
be the reason for low brake fluid in the res-
ervoir.
Have the brake system inspected 
immediately. Contact an authorized 
Mercedes-Benz Light Truck Center.
All checks and service work on the brake 
system should be carried out by qualified 
technicians only. Contact an authorized 
Mercedes-Benz Light Truck Center.
Install only brake pads and brake fluid 
recommended by Mercedes-Benz.Warning!
G
With the engine not running, there is no 
power assistance for the brake and steering 
systems. In this case, it is important to keep 
in mind that a considerably higher degree of 
effort is necessary to brake and steer the ve-
hicle.Warning!
G
After driving in heavy rain for some time 
without applying the brakes or through wa-
ter deep enough to wet brake components 
or salty road conditions, the first braking ac-
tion may be somewhat reduced and in-
creased pedal pressure may be necessary to 
obtain expected braking effect. Maintain a 
safe distance from vehicles in front.
Resting your foot on the brake pedal will 
cause excessive and premature wear of the 
brake pads. 
It can also result in the brakes overheating, 
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the 
vehicle in sufficient time to avoid an acci-
dent.
!Be very careful not to endanger other 
road users when you apply the brakes. 
Refer to the description of the Brake 
Assist System (BAS) (
page 82).
