Tyre pressure
Notes on tyre pressure
& WARNING Risk of accident due to insuf‐
ficient or excessive tyre pressure
Underinflated or overinflated tyres pose the
following risks:

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
