WARNING (continued)
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 correctly tight-
ened.
For the sake of the environment
Under-inflated tyres will increase the fuel consumption.
Note
When checking tyre pressures, please observe the instructions for the tyre
control system page 220.
Safety First Operating instructions
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 particularly
important when driving in winter, in cold temperatures and on wet roads
.
The minimum tread depth required by law in the majority of cases is 1.6 mm
(1/16 of an inch), measured in the tread grooves next to the tread wear indi-
cators. Observe legal requirements in each country.
The performance of winter tyres is much reduced when the tread has worn to
4 mm (5/32 inch).
The tread depth of new tyres may vary, according to the type and make of tyre
and the tread pattern.
Wear indicators on the tyre
The original tyres on your vehicle have 1.6 mm (1/16 inch) high
tread wear indicators running across the tread. A number of these indicators
