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

Cruise control may be unable tomaintain the

speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long

no te ofthis when driving a laden vehicle. By
doing so, you will make use of the engine's brak‐

Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the

R Ifyo u are driving when visibility is poor.
Fu nction of the limi ter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:
R Variable: for speed restrictions, e.g. in built-
up areas.
R Perm anen t:for long-term speed restrictions,
e.g. when driving in winter tyre mode.
The variable limiter is operated using the cor re‐
sponding steering wheel buttons. You can store any
road speed from 30 km/h to250 km/h or
up tothe set winter tyre limit. You can also per‐
fo rm settings while theve hicle is stationary if
