Riskofaccident
The tyrepressure loss warning system can
only give reliable warnings if you have setthe
correcttyrepressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
Atyre with insufficient pressure results in
vehicle instability when driving, thusincreas-
ing the risk of an accident.

Direction of rotation
Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergencyspare wheel/spare
wheel against the direction of rotation.
Observe the timerestriction on use as well as
the speed limitation specified on the emer-
gencyspare wheel/sparewheel.
Interchanging thewheels
G
Riskofaccident
Interchange the front and rear wheels only if
they have the same dimensions: for example
size, offset, etc.
After every wheel interchange/change, have
the tightening torque checked at aqualified
specialist workshop that has the necessary
specialist knowledgeand toolstocarry out
the work required. Mercedes-Benz recom-
mends that you use aMercedes-BenzService
Centrefor this purpose. In particular,work
relevant to safetyoronsafety-related sys-
tems must be carried out at aqualified spe-
cialist workshop.
The wheelscould work loose if they are not
tightened to atorqueof130 Nm.
