Brake service
If the parking brake is released and the red
brake warning lamp in the instrument clus-
ter stays on, there is a malfunction in the
electro-hydraulic brake system
(
୴ page 307) or 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
reservoir.
Observe additional messages that may
appear in the multifunction display
(
୴ page 335).
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and brake fluid
recommended by Mercedes-Benz.
To avoid this danger, you should:
ț occasionally brake carefully when you
are driving on salted roads, so that any
layer of salt that may have built up on
the brake discs and the brake linings is
removed without putting other road us-
ers at risk
ț maintain a greater distance to the vehi-
cle ahead and drive with particular care
ț carefully apply the brakes at the end of
a trip and immediately after commenc-
ing a new trip, so that salt residues are
removed from the brake disc
!
Because the ESP
®
operates automatically,
the engine must be shut off (SmartKey in starter
switch position 0 or 1) when the parking brake is
being tested on a brake test dynamometer.
Active braking action through the ESP
®
may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
Warning! G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.
Be certain to read and observe the warning
notices on brake pad replacement
(
୴ page 89).
