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 )

Maintenance and care

Ac
cording toEuropean standard EN 1694 2you
can find the compatibility indications at thefo l‐
lowing locations:
R ontheve hicle on the information label in the
fuel filler flap
R onthe fuel pump or pump nozzle suitable for
yo ur vehicle thro ughout Europe
The recommended octane number foryo ur vehi‐
cle can also be found on the information label in
th e fuel filler flap .
On lyrefuel using super-grade petrol with at least
98 RON if you wish toachie vemaximum engine
output. Alternatively, you can also refuel using
premium grade petrol with at lea st95 RON.
In exc eptional cases, if there commended fuel is
not available, you may also use regular unleaded
petrol with an octane number of at least 91RON.
This may reduce engine output and increase fuel
consum ption.
If only regular unleaded petrol with 91RON or
lo we r is permanently available toyou, you must
ta ke your vehicle toaqu alified specialist work‐
shop tohave it adap tedto this type of fuel. Ne

The brake fluid constantly absorbs moisture
from the air. This lo wersthe boiling point of

This impairs the braking ef fect. #
