& WARNING Risk of aquaplaning because
tyre tread is too low
Depending on the depth of the water on the
roadway, aquaplaning can occur despite suffi‐
cient tyre tread depth and low speed.
Avoid tyre ruts and brake carefully.

Example: tyre tread wear indicator
A specified minimum tread depth is a legal
requirement for all tyres. Observe the legal
requirements for the country you are currently in.
The less tyre tread depth remaining, the poorer
the road adhesion and handling characteristics of
the vehicle, particularly if the roadway is wet or
snow-covered. A tyre has reached the minimum
tread depth when the tread wear indicator
(arrow) is flush with the tyre tread.
Tyre pressure
Vehicles with tyre pressure monitoring system:
you can have the current pressure of the individ‐
ual tyres displayed in the multimedia system.
Press the 3 button under the
item in the
Status
menu of the multimedia sys‐
tem to do this.
& WARNING Risk of accident due to insuf‐
ficient or excessive tyre pressure
Underinflated or overinflated tyres pose the
following risks:
The tyres may burst, especially as the
R
load and vehicle speed increase.
The tyres may wear excessively and/or
R
unevenly, which may greatly impair tyre
traction.
The driving characteristics, as well as
R
steering and braking, may be greatly
impaired.
Comply with the recommended tyre
#
pressure and check the tyre pressure of
all tyres including the spare wheel regu‐
larly:
at least once a month
R
when the load changes
R
before embarking on a longer journey
R
if operating conditions change, e.g. off-
R
road driving
Adjust the tyre pressure as necessary.
#
Tyre pressure that is too low can have the follow‐
ing consequences:
severe heating
R
increased tyre wear
R
changed driving stability
R
increased fuel consumption
R
Tyre pressure that is too high can have the follow‐
ing consequences:
greater braking distance
R
poorer tyre traction
R
increased tyre wear

& WARNING Risk of accident from repea‐
ted tyre pressure drop
If the tyre pressure drops repeatedly, the
wheel, valve or tyre may be damaged.
Insufficient tyre pressure can cause the tyres
to burst.
Inspect the tyre for signs of foreign

menu
objects.
Check whether the wheel or valve has a
#
leak.
If you are unable to rectify the damage,
#
contact a qualified specialist workshop.
& WARNING Risk of accident through
reducing the tyre pressure when the tires
are hot
The tyre temperature and pressure increase
when the vehicle is in motion. Reducing the
pressure of warm tyres leads to a tyre pres‐
sure that is too low when the tyres have
cooled.
If the tyre pressure is too low, it may cause
the tyre to burst, especially when the load or
speed increases.
