Brake sy
stem Note
s onthe brake sy stem
The brake sy stem of your vehicle is designed for
heavy loads. Therefore, there may be noise when
braking. The loads in the entire brake sy stem
which occur when driving on a racetrack are sig‐
nificantly grea terth an those during normal oper‐
ation.
The increased brake forc es and temp eratures
when driving on a racetrack inhe rently lead to
inc reased wear of the brake sy stem.
Check the condition and geometry of the brake
co ver plate before using theve hicle on a race‐
trac k.
Obser vethe information on the cooling of com‐
ponents which are subject tostra in when oper‐
ated on a racetrack (/ page 109).
Braking with ABS
Re peated hard braking within the ABS control
ra nge causes higher temp eratures in the brake
sy stem than controlled braking shortly before
th e ABS control limit. Brakepad
wear
The inner and outer brakepads may also suf fer
"tapered wear". This could lead topoor pedal
fe el. Therefore, you must also check the condi‐
tion of the brakepads before and af ter use on a
ra cetrack as part of astandard check forwe ar.
Brake discs
Obse rveth e information on the cooling of com‐
ponents which are subject tostra in in racetrack
ope ration (/ page 109).
Depending on theve hicle's equipment, the AMG
ceramic high-per form ance composite braking
sy stem is fitted in your vehicle. The assessment
of we ar must therefore be car ried out using a
special measurement procedure. The brakes are
measured using the cur rent condition of the
ceramic composite material as a criteria for
assessing thewe ar ins tead of assessing the
re sidual thickness.
Depending on the type of brake disc, thefo llow‐
ing are combinations used tomeasu rethewe ar
of the brake discs:
R Carbon-ceramic brake disc -
Visual assessment of the brake disc for
mechanical dama ge
- Wear measurement using the indicator
fi eld me thod; alternatively using the Pro‐
ceq Carbo teq®
measu ring device (e.g. in
th e AMG Performance Center or at AMG
Tr ackda ys)
R Grey cast iron brake disc
- Visual check
- Crack test
- Wearthickness test
The ventilation holes on gr eycast iron friction
ri ngs of standard brake discs in particular could
become bloc kedby brake dust. Therefore, check
th eve ntilation holes be fore using theve hicle on
a ra cetrack and clean them if necessar y.If nec‐
essar y,also clean the drilled holes.

Driving and pa rking

Check
the tyres for dama geand the cor rect tyre
tread dep thboth before and af ter use on a race‐
trac k.Only then is it safe todrive on a racetrack
and on public roads.
As a result of the driving style and at high ambi‐
ent temp eratures, when driving on a racetrack it
may be necessary tocompensate forthe
inc rease in pressure in warm tyres byreleasing
air. Even forwa rm tyres, the specified tyre pres‐
sure may only be exceeded bymax. 0.5 bar.
Af terth e tyres ha vecooled down again, you
must readjust the tyre pressure in accordance
with the specifications in order todrive on public
ro ads. Suspension
Suspension settings
The
factory setting pr ovides a good compromise
fo r driving on public roads and on a racetrac k.
Ve hicle measurements
Even small changes tothe suspension settings
alter the driving characteristics of theve hicle. To
ensure optimal driving characteristics, the speci‐ fi
ed values and tolerances of the individual sus‐
pension settings must be complied with. The
driving characteristics of theve hicle may other‐
wise be undesirable.
Ve hicle measurements are requ ired in thefo llow‐
ing situations:
R theve hicle height has changed in relation to
th e optimised setting.
R theve hicle is frequently subjected tovery
high loads, e.g. when driving over kerbs.
Therefore, check theve hicle height at regular
inter vals and, if necessar y,per form vehicle
measurements.
Note s on suspension components
Despite regular checks, and rega rdless of
whe ther there leva nt suspension components
are in good condition, thefo llowing components
must be replaced af ter a cer tain amount of use
on thera cetrack:
R Wheel bolts (/ page 111 )
R Wheel hubs including the wheel bearings Note

vehicle sensors and cameras 1
Multifunction camera
2 Front camera
3 Ultrasonic sensors
4 Reversing camera
% Depending on theve hicle's equipment, the
ra dar sensors are integ rated behind the
bumpers and/or behind thera diator grille. Some driving and driving saf
ety sy stems use
cameras and sensors tomonitor the area in
front of, behind or next totheve hicle.
Ke ep the areas around the sensors and cameras
free of dirt, ice or slush (/ page 293). The cam‐
eras and sensors must not be co vered, forex am‐
ple bybicycle rack s, overhanging loads, sticke rs,
fo il or foils toprotect against stone chipping.
Ad ditional licence plate brac kets can impair the
function of the ultrasonic sensors, in particular.
In theeve nt of damage or a severe impact in the
area of the sensors, ha vethe function of the
sensors checked at a qualified specialist work‐
shop. Ha vedamage or stone chipping in the area
of the cameras repaired at a qualified specialist
wo rkshop. If the sensors or cameras are dam‐
aged, some driving sy stems and driving saf ety
sy stems may no longer function proper ly. Overview of driving sy
