Four-wheel drive
(quattro)
Applies to vehicles: with four-wheel drive
On quattro models the engine power is dis-
tributed to all four wheels.
General notes
On four-whee l drive vehicles, the engine pow-
er is distributed to all four wheels. The distri-
bution of power is controlled automatically
accord ing to your driving style and the road
conditions. Also refer to ¢ page 182, Elec-
tronic stabilisation control (ESC).
The four-wheel drive is specially designed to
complement the superior engine power of
your Audi. This combination gives the car ex-
ceptional handling and performance capabili-
ties - both on normal roads and in more diffi-
cult conditions, such as snow and ice. Even so
(or perhaps especially for this reason), it is im-
portant to observe certain safety points ¢ & .
Winter tyres
Thanks to its four-wheel drive, your ca r will
have plenty of traction In winter conditions,
even with the standard tyres. Nevertheless,
we sti ll recommend that winter tyres or a ll-
season tyres should be fitted on oil four
wheels when winter road conditions are ex-
pected, mainly because th is will give a better
braking response .
Snow chains
On roads where snow chains are mandatory,
this also applies to cars with four-wheel drive
¢ page 228, Snow chains .
Replacing tyres
On vehicles with four-wheel drive, all four
tyres must have the same rolling circumfer-
ence. Also avoid using tyres with varying tread
depths ¢ page 225, Replacing wheels and
tyres. ..,_
