Vehicles with Active Parking Assist: do
not use Active Parking Assist when snow
chains are fitted.

You can permanently limit the maximum
vehicle speed for driving with winter tyres
(/ page 212).
%
You can deactivate ESP
®
to pull away
(/ page 201). This allows the wheels to
spin, achieving an increased driving force.

WARNING Risk of accident due to insuf‐
ficient or excessive tyre pressure
Underinflated or overinflated tyres pose the
following risks:
R
The tyres may burst, especially as the
load and vehicle speed increase.
R
The tyres may wear excessively and/or
unevenly, which may greatly impair tyre
traction.
R
The driving characteristics, as well as
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:
R
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-
road driving
#
Adjust the tyre pressure as necessary.
Tyre pressure which is too high or too low can:
R
Shorten the service life of the tyres.
R
Cause increased tyre damage.
R
Adversely affect driving characteristics and
thus driving safety, e.g. due to aquaplaning.
&
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
objects.
#
Check whether the wheel or valve has a
leak.
#
If you are unable to rectify the damage,
contact a qualified specialist workshop.
Information on the recommended tyre pressure
for the vehicle's factory-fitted tyres can be found
on the tyre pressure table on the inside of the
socket flap (/ page 492).
Use a suitable pressure gauge to check the tyre
pressure. The outer appearance of a tyre does
not permit any reliable conclusion about the tyre
pressure.
