Driving with your
quattro
Applies to veh icles: w it h all -w hee l drive
-
With all-wheel drive, all four wheels are driv­
en.
General information
With all-wheel drive, power is distr ibuted to
all four wheels. This happens automatically
depending on your driving style and the road
cond it ions at the time. See also
Qpage 193.
A center differential distributes the driving
power variably to the front and rear axle.
It
works together with selective wheel torque
control, wh ich activates when driving through
curves ¢
page 194. With the sport differen­
tia l*, power distribution to the rear wheels is
variable and can be adjusted with drive se lect
¢ page 100.
The all-whee l drive concept is des igned for
high engine power. Your vehicle is exception­
ally powerful and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions ¢

-If you notice unusual vibra­tion or if the vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so and check the
wheels and tires for dam­ age.
(D Note
-Please note that summer and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability.
Tires and wheels 239
If summer tires are used in
very cold temperatures, cracks can form on the tread bars, resulting in perma­
nent tire damage that can
cause loud driving noise and unbalanced tires. Audi is not
responsible for this type of
damage .
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.

which may be replaced) of auto­ matic transmission, power
steering, power brakes , power
windows, power seats, radio, and heater, to the extent that
these items are available as fac­
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent. Numbers of 55 or lower indi­
cate a low sidewall for im­ proved steering response and
better overall handling on dry
pavement.
