Underinfla ted or overinfla ted tyres pose the
fo llowing risks:
R The tyres may bur st, especially as the
load and vehicle speed increase.
R The tyres may wearexc essively and/or
une venly, which may greatlyimpair tyre
traction.
R The driving characteristics, as well as
st eering and braking, may be greatly
impaired. #
Comply with there commended 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 lon ger journey
R if operating conditions change, e.g. off-
ro ad driving #
Adjust the tyre pressure as necessar y. Driving wi

WARNING Risk of accident from repea‐
te d tyre pressure drop
If th e tyre pressure drops repeatedl y,the
wheel, valve or tyre may be damaged.
Insuf ficient tyre pressure can cause the tyres
to bur st. #
