Un derin0a tedorove rin0ated ty res pose in par-
ticular thefo llowing risks:
R The tyres can burst. R
The tyres can wearexcessively and/or
une venly.
R The driving characteristics as well as the
stee ring and braking characteristics may
be greatly impaired. #
Comply with there commended tyre
pressure and check the tyre pressure of
all tyres, including the spare wheel, regu-
lar ly:
R monthly
R when the load changes
R before embarking on a lon ger journey
R if operating conditions change, e.g. o.-
ro ad driving #
Adjust the tyre pressure, if necessar y. Ty
re pressure which is too high or too low can:
R Shor tenth e service life of the tyres.
R Cause increased tyre damage.

The wheels, valves or tyres could be damaged.
To o low a tyre pressure can lead tothe tyres
bursting. #
Examine the tyres forfo re ign objects. #
Check whe ther the tyre has a puncture
or theva lve has a leak. #
Ifyo u are unable torectify the damage,
contact a quali/ed specialist workshop. Information on
there commended tyre pressure
fo rth eve hicle's factor y-/tted tyres can be found
on the tyre pressure table on the inside of the fuel

Use a suitable pressure gauge tocheck the tyre
pressure. The outer appearance of a tyre does not
permit any reliable conclusion about the tyre pres-
sure.
Only cor rect tyre pressures when the tyres are
cold. Conditions for cold tyres:
R The vehicle has been par ked with the tyres out
of direct sunlight for at least thre e hours. R
The vehicle has tr avelled less than 1.6 km.
The vehicle's tyres heat up when driving. As the
te mp erature of the tyres increases, so too does
