2020 MERCEDES-BENZ AMG GT ROADSTER air suspension

When driving on a
racetrac k,make sure that the
brake fluid is not more than 12 months old.
Brake callipers, brake hoses and brake lines
Check thefo llowing for dama geeach time
before driving theve hicle on a racetrack:
R The du stboots on the brake callipers
R The brake hoses and brake lines
Re place them if necessar y.
Brake cooling
Special air deflectors and channels are fitted to
th e front and rear axles so that the brakes are
cooled suf ficiently. They supply the brake disks
with cooling air. Check that they are in per fect
condition and cor rectly fitted ea chtime be fore
driving theve hicle on a racetrac k.Excessi ve
we ar can be caused bydriving overke rbs, for
ins tance. Forth is reason, regularly check they
are all comple teand fitted securely.
In addition, check that the air guide plates are
seated securely and clean before and af ter driv‐
ing theve hicle on a racetrac k. Obser

ponents which are subject tostra in in when driv‐

Only use the wheels pr ovided by
Mercedes-AMG for use on a racetrac k. #
Only use wheels with appr ovedge ome‐
tr y. Do not use slick tyres. Suspension and body
components may
otherwise be subjected to
exc essively high loads. Obser
vethefo llowing no tes on changing a
wheel:
R change the wheels af ter15 ,000 km on a
ra cetrack at the latest.
R toensure concent ricity and la tera l trueness,

be measured in theeve nt of imbalance.
The wheel bolts are subjected tohigh wear when
used on a racetrac k.To ensure the wheels are
bolted securely on a permanent basis, replace

Damaged tyres can cause tyre pressure loss. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres

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 116)
R Wheel hubs including the wheel bearings Note

Note
s on inter changing wheels &
WARNING Risk of injury thro ugh dif fer‐
ent wheel sizes
Inter changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions
may se verely impair the driving characteris‐
tics.
The disk brakes or wheel suspension compo‐
nents may also be damaged. #
Rotate front and rear wheels on lyifthe
wheels and tyres are of the same
dimensions. Inter
changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions can
re nder thege neral operating pe rmit in valid.
The wear pat tern s on the front and rear wheels
dif fer:
R Front wheels wear more on the shoulder of
th e tyre
R Rear wheels wear more in the cent reofthe
tyre Do not drive wi
thtyres that ha vetoo little tread
dep th. This significantly reduces traction on wet
ro ads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5,000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for
th e wheels.
Obser vethe instructions and saf ety no tes on
"Changing a wheel" when doing so
(/ page 272). Note
s onstoring wheels When
storing wheels, obser vethefo llowing
no tes:
R Afterre moving wheels, store them in a cool,
dry and preferably dark place.
R Protect the tyres from conta ct withoil,
grease or fuel. Overview of
the ty re-change tool kit Apart from some countr
y-specific variants, vehi‐
cles are not equipped with a tyre-change tool kit.
Fo r more information on which tyre-changing
to ols are required and appr oved for per form ing a
wheel change on your vehicle, consult a qualified
specialist workshop.
Re quired tyre-change tool kits may include, for
ex ample:
R Jack
R Chock
R Wheel wrench
R Cent ring pin
% The jack weighs appr oximately 1.2 kg.
The maximum load capacity of the jack can
be found on thest icke r af fixe dto the jac k.
The jack is maintenance-free. If there is a
malfunction, please conta ct aqualified spe‐
cialist workshop. Wheels and tyres
