206 Vehicle care and maintenance
Checking tyre pressures
Check tyre pressures only when the vehicle has not been driven for more
than a few kilometres at low speeds in the past three hours.
● Check tyre pressures regularly, and only when the tyres are cold. Always
check all tyres, including the spare wheel. Check tyre pressures more often
in colder regions, and only when the vehicle has not been driven recently.
Always 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.
The spare wheel or temporary spare wheel must be at the maximum pres-
sure specified.
WARNING
If tyre pressures are too high or too low, the tyre may deflate or burst
suddenly while driving. This could result in serious accident.
● If the tyre pressure is too low, the tyres could overheat, resulting in
tread detachment or even burst tyres.
● When driving at high speeds and/or fully loaded, the tyre could sud-
denly overheat, burst or be subject to tread detachment, with the resul-
tant loss of control of the vehicle.
● Tyre pressures which are too high or too low reduce the service life of
the tyre, affecting the vehicle's performance.
● Tyre pressures should be checked regularly, 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 care not to tilt the manometer when placing it on the valve. Other-
wise, the valve may be damaged.
● To avoid damage to the valves, always replace valve caps correctly.
Check that the caps are identical to the standard caps and have been cor-
rectly tightened.
For the sake of the environment
Under-inflated tyres will increase the fuel consumption.
Tread depth and wear indicators
Tread depth
Certain driving conditions require a deeper tread, as well as needing the
tread to be approximately the same on the front and rear tyres. This is par-
ticularly important when driving in winter, in cold temperatures and on wet
roads ⇒
