maintain the correct tyre pressures, especial-
ly if driving at high speeds. Incorrect tyre
pressure causes premature wear and could
cause tyre blow-out.
The pressure should therefore be checked at
least once a month and before starting a
journey.
As a general rule, the pressures given are for
cold tyres. When the tyres are hot, the pres-
sures are greater.
Never deflate a hot tyre in order to obtain the
required pressure. This could result in very
low tyre pressures which may lead to sudden
blow-outs.
Tyre pressure monitoring system
Check tyre pressures only when the vehicle
has not been driven for more than a few kilo-
metres at low speeds in the past three hours.
●
The tyre pressures should be checked regu-
larly, and only when the tyres are cold. Al-
ways check all tyres, including the spare
wheel. Tyre pressures should be checked
more often in colder regions, and only when
the vehicle has not been driven recently. Al-
ways use a correctly-operating tyre gauge.

●
Adjust tyre pressures to the loads carried in
the vehicle.
●
After adjusting the tyre pressure, check that
the caps are properly screwed on.
. It is essential to
The spare wheel or temporary spare wheel
must always be kept at the maximum pres-
sure stipulated.
WARNING
If tyre pressures are too high or too low, the
tyre may deflate or burst suddenly while driv-
ing. This could result in a serious accident.
If the tyre pressure is too low, they could
●
overheat, resulting in tread detachment or
even burst tyres.
When driving at high speeds and/or fully
●
loaded, the tyre could suddenly overheat,
burst or be subject to tread detachment, with
the resultant loss of control of the vehicle.
●
Tyre pressures which are too high or too
low reduce the service life of the tyre, affect-
ing the vehicle's performance.
●
Tyre pressures should be checked regularly,
at least once a month and before long jour-
neys.
●
Adjust the pressures of all the tyres to the
vehicle load.
●
Never deflate excess pressure from hot
tyres.
Advice
CAUTION
●
Take care not to tilt the manometer when
placing it on the valve. Otherwise, the valve
may be damaged.
●
If tyre valves are not protected by caps, or if
the caps are not screwed on correctly, they
may become damaged. Check that the caps
are identical to the standard caps and have
been correctly tightened.
For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption.
