. It is essential to
maint
ain the corr
ect t
yre 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 reg-
ularly, 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.
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 defl
ate or burst suddenly while
driving. This could result in a serious acci-
dent.
●
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 ve-
hicle.
●
Tyre pressures which are too high or too
low reduce the service life of the tyre, af-
fecting the vehicle's performance.
●
Tyre pressures should be checked regu-
larly, at least once a month and before
long journeys.
●
Adjust the pressures of all the tyres to the
vehicle load.
●
Never deflate excess pressure from hot
tyres.
CAUTION
●
Take car
e 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.
