High-performance andceramic brake

AMG brake systems aredesig nedfor
heavy loads.This may leadto noise when
braking. Thiswilldepend on:
R Speed
R Braking force
R Ambient conditions, e.g.temperature and
humid ity
The wearof individ ualcomponents ofthe
brake system, suchasthe brake pads/linings
or brake discs, depends onthe individ ualdriv-
ing style andopera tingconditions.
For this reason, itis impossi bletostate amile-
age that willbe vali dunder allcircumstances.
An aggres sivedriving stylewilllea dto high
wea r.You canobtain moreinformation onthis
from aqua lifiedspecia listworkshop.
New andrepla cedbrake padsanddiscs only
reach theiroptimum brakingeffectaftersev-
eral hundred kilometers ofdriving. Compen-
sate forthis byappl ying greater forcetothe
brake pedal.Keep thisinmind, andadaptyou r
driving andbraking accordingly duringthis
break-in period.
Excessive heavybraking resultsincorrespond-
ingly highbrake wear.Observe thebrake sys-
tem warning lampinthe instrument cluster and
note anybrake status messag esinthe
multifu nctiondisplay.Especial lyfor high per-
formance driving,itis important tomaintain
and have thebrake system checked regularly. Drivin

Hydroplaning If

For this reason, inthe event ofheavy rainorin
conditions inwhich hydroplaning mayoccur,
you must driveinthe follow ingmanner:

Do
not drive through floodedarea s.Check
the depth ofany water before driving
through it.Drive slowlythrough standing
water. Otherwise ,water couldenterthe

can then dama gethe engine's orautoma tic

can also besucked inby the engine's air
