Brakes
To 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.
Refer to the description of the Brake Assist 
System (BAS) (
Brake pad wear or a leak in the system may 
be the reason for low brake fluid level in 
the reservoir.
The brake fluid level in the reservoir may 
be too low if the red brake warning lamp in 
the instrument cluster comes on while the 
engine is running and an acoustic warning 
sounds (
messages in the multifunction display that 
may appear (
Warning!
G
After driving in heavy rain for some time 
without applying the brakes or through wa-
ter deep enough to wet brake components, 
the first braking action may be somewhat 
reduced and increased 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 
accident.
!
Vehicles without 4MATIC: 
Because the ESP
®
 operates automatically, the 
engine and ignition must be shut off (SmartKey 
in starter switch position 0 or 1 or KEYLESS-GO 
(Canada only) start/stop button* in position 0 
or 1) when
the parking brake is being tested on a brake 
test dynamometer
the vehicle is being towed with the front axle 
raised
Active braking action through the ESP
®
 may oth-
erwise seriously damage the brake system.
Warning!

Make sure not to endanger any other road 
users when carrying out these braking ma-
neuvers.
