brake is released. Observe additional mes-
sages in the multifunction display that may
appear.
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 immedi-
ately. Contact an authorized Mercedes-
Benz Center.
All checks and service work on the brake sys-
tem should be carried out by qualified tech-
nicians only. Contact an authorized Mer-
cedes-Benz Center.
Only install brake pads and brake fluid rec-
ommended by Mercedes-Benz.
G
Warning!
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.
!
Because the ESP
®
operates automati-
cally, the engine and ignition must be shut
off (SmartKey in starter switch position 0
or 1) when the parking brake is being
tested on a brake test dynamometer or
when the vehicle is being towed with the
front axle raised.
Active braking action through the ESP
®
may otherwise seriously damage the brake
system which is not covered by the Mer-
cedes-Benz Limited Warranty.
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.
G
Warning!
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
Refer to the description of the Brake Assist
System (BAS) (Y page 60).
High-performance brake system
The high-performance brake system is only
available on SLK 55 AMG.
G
Warning!
New vehicle brake pads and discs, and
replacement brake pads and discs may
take several hundred miles of driving until
they provide optimum braking efficiency.
Until that time, you may need to use
increased brake pedal pressure while brak-
ing. Please be aware of this and adjust your
driving and braking accordingly during this
break-in period.
Excessive high-demand braking will cause
correspondingly high brake wear. Please be
attentive to the brake warning lamp in the
instrument cluster and brake condition
messages in the multifunction display.
Especially for high performance driving, it
is important to maintain and have the brake
system checked regularly.
The high-performance brake system is
designed to operate under the extremely high
operating demands required to accommo-
date the performance capabilities of the vehi-
cle.
