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 ¢
page 102, Electronic stabilisation con
trol (£SC).
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

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
¢
page 234, 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
¢
page 231, New wheels or tyres.
Off-road er?
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.

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
conditions - 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).
Rear spoiler
Applies to vehicles: with automatic rear spoiler
The automatic rear spoiler increases the car's
stability.
