The braking characteristics of thevehiclecan
be seriouslyimpaired if:
Rbrakepads other than those recommended
are installed
Rtherecommended brakefluid is notused
Safe braking can no longer be guaranteed.
AMG high-performance and ceramic
brakes
The high-performance brake system is
installed only on the CLS 63 AMG.
The AMG brake systems are designed for
heavy loads. This may lead to noise when
braking. This will depend on:
RSpeed
RBraking force
REnvironmental conditions, such as
temperature and humidity
The wear of individualcomponentsofthe
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.
For this reason, it is impossibletostate a
mileage that will be valid under all
circumstances. An aggressive driving style
will lead to high wear. You can obtain further
information aboutthis from your authorized
Mercedes-BenzCenter.
