All wheel
drive
(quattro)
Appl ies to: vehicles wit h all wheel drive
In oil wheel drive, oil four wheels ore powered .
General information
In all wheel drive, the driving power is divided be-
tween all four wheels . This happens automatical -
ly depending on your driving behavior as well as
the current road conditions. Also see
c:>
page 119, Electronic stabilization control
(ESC) .
A center differential distributes the driving power
variab ly to the front and rear axle. It works to-
gether with selective wheel torque control, which
activates when driving through curves
c:>poge 119. With the sport differential*, power
distribution to the rear wheels is variable and can
be adjusted w ith drive select c:> poge 104 .
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics
both under normal dr iving cond itions and on
snow and ice. Always read and fo llow safety pre-
cautions

Winter tires
By using all wheel drive, your vehicle has good
forward mot ion with standard tires in winter con-
ditions . However, in winter we recommend using
winter or all season tires on all four w heels, be-
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:>
page 217, Snow chains .
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used .
Avoid using tires with different tread depths
c:>
page 208, New tires or wheels .
Offroad vehicle?
Your Audi is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.

WARNING
-
-
- Also, in veh icles with all wheel drive, adapt
your driving style to the current road and
traffic cond itions . Do not let the increased
safety prov ide d tempt you into taking risks,
because this incr eases the risk of an acci-
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two w heel drive vehi -
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be-
cause t his increases the risk of an accident .
- Note that on wet streets, the front wheels
can "hydrop lane" if driving at speeds that
are too high . Unlike front wheel drive
veh icles, the engine does not rev higher sud-
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci-
dent.
Energy
management
Your vehicle is equipped with an intelligent ener-
gy management
system for distributing electrici-
ty . This sign ificantly improves the start ing ability
and increases the vehicle battery life.

Tips
- If you dr ive short distances frequently, the
veh icle battery may not charge enough
w hile driving. As a result, convenience func-
tions for e lectr ical equipment may be tem-
porarily unavailable.
- The ve hicle battery w ill gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be reduced or
switched off.
