The tires may wear excessively and/or
R
unevenly, which may greatly impair tire
traction.
The driving characteristics, as well as
R
steering and braking, may be greatly
impaired.
Comply with the recommended tire
#
pressure and check the tire pressure of
all tires 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 tire pressure as necessary.
#
Driving with tire pressure that is too high or too
low can:
Shorten the service life of the tires.
R
Cause increased tire damage.
R
Adversely affect handling characteristics and
R
thus driving safety, e.g. due to hydroplaning.
& WARNING Risk of an accident due to
insufficient tire pressure
Tires with pressure that is too low can over‐
heat and burst as a result.
In addition, they also suffer from excessive
and/or irregular wear, which can significantly
impair the braking properties and the han‐
dling characteristics.
Avoid excessively low tire pressures in
#
all the tires, including the spare wheel.
Tire pressure which is too low can cause:
Tire defects as a result of overheating.
R
Impaired handling characteristics
R
Irregular wear
R
Increased fuel consumption

& WARNING Risk of accident from exces‐
sive tire pressure
Tires with excessively high pressure can
burst because they are damaged more easily
by highway fill, pot holes etc.
In addition, they also suffer from irregular
wear, which can significantly impair the brak‐
ing properties and the handling characteris‐
tics.
Avoid excessively high tire pressures in
#
all the tires, including the spare wheel.
Excessively high tire pressure can result in:
Increased braking distance
R
Impaired handling characteristics
R
Irregular wear
R
Impaired driving comfort
