Note on driving with the electrohydraulic
brake system
Following extended periods of only minor
loads to your brake system, you
should occasionally apply the brakes
when traveling at high speeds. This improves
the grip of the brake pads and
prevents possible brake noise.
After driving on wet or snow-covered
roads, you should apply your brakes
firmly before parking your vehicle. This
produces heat which serves to dry the
brake disks.
Warning! G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
On long and steep grades, shift to a
lower gear (gear range 1, 2, or 3) to
prevent the brakes from overheating
and to reduce brake wear.
After hard braking, it is advisable to
drive on for some time so that the air
stream will cool down the brakes faster.
Only Mercedes-Benz approved components
(e.g. brake pads) should be installed
on your vehicle. Brake pads not
approved by Mercedes-Benz may impair
the safety of your vehicle.
