Four-wheel drive
(quattro)
Applies to: vehicles with four-wheel drive
On quattro models the engine power is distrib­
uted to all four wheels.
General notes
On four-wheel drive vehicles, the engine power is
distributed to all four wheels. The distribution of
power is controlled automatically according to
your driving style and the road conditions. Also
refer to q page 121, Electronic stabilisation con­
trol (ESC).
The four-wheel drive is specially designed to
complement the superior engine power of your
Audi. This combination gives the car exceptional
handling and performance capabilities - both on
normal roads and in more difficult conditions,
such as snow and ice. Even so (or perhaps espe­
cially for this reason), it is important to observe
certain safety points q .&..

Winter tyres
Thanks to its four-wheel drive, your car will have
plenty of traction in winter conditions, even with
the standard tyres. Nevertheless, we still recom­
mend that winter tyres or all-season tyres should
be fitted on all four wheels when winter road
conditions are expected, mainly because this will
give a better braking response.
Snow chains
On roads where snow chains are mandatory, this
also applies to cars with four-wheel drive
q page 242, Snow chains.
Replacing tyres
On vehicles with four-wheel drive, all four tyres
must have the same rolling circumference. Also
avoid using tyres with varying tread depths
q page 238, New wheels or tyres.
Off-roader?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle. It is there­
fore best to avoid rough tracks and uneven ter­
rain as much as possible.
A
WARNING
- Even with four-wheel drive, you should al­
ways adjust your speed to suit the condi­
tions. Do not let the extra safety provided
tempt you into taking any risks when driving
- this can cause accidents.
- The braking ability of your car is limited by
the grip of the tyres. In this respect, your car
is no different from a car without four-wheel
drive. So do not be tempted to drive too fast
on icy or slippery roads just because the car
still has good acceleration in these condi­
tions - risk of accident!
- On wet roads bear in mind that the front
wheels may start to "aquaplane" and lose
contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as with a front-wheel drive car. So do
not drive too fast in the wet: adjust your
speed to suit the conditions (accident risk).
