tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the veh icle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv ­
i n g on curves . The front wheel on the inside of
the c urve or both wheels on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves.
Automatic post-collision braking system
The "Automatic post-collision brak ing system"
can help to reduce the r isk of slid ing and of other
coll is ions after an accident . If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if :
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri­
cal system are not functioning.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits posed by natural physi-
Switching on and off
cal laws. This is especially important on slip­
pery or wet roads. If the systems beg in act­
ing to stabilize your vehicle, you should im­
mediately alter your speed to match the
road and traffic conditions. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
- Please note the risk of a collision increases
when dr iv in g fast, especially through curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a risk of acci­
dents!
- Press the accelerator peda l carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision .
@ Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
£SC turns on automatically when you start the engine .

The ESC is designed to function in levels. Depend­
i ng on the level that is selected, the stabilization
function of the ESC is limited or switched off. The amount of stabilization control will differ de­
pending on the level.
The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Dr iving in deep snow or on loose ground

Power steering adapts electronically based on
the vehicle speed .
Indicator lights and mess ages
• Steering fault! Do not drive veh icle!
If thi s ind ic a tor light t urns o n and stays o n and
this message appears, the power steering may
have fa iled.
S top the veh icle in a safe lo cat io n as soo n as pos­
sib le. Do
not c on tinue driving. See an author ized
Aud i dea ler o r authorized Aud i Serv ice Facility fo r
assistance.
If the ind icator lig ht t urns on, the steer ing wheel
may be mo re diff icu lt to move o r more sensitive
than usual. The stee ring wheel may also be at a n
angle when dr iving straight .
Dr ive s low ly to your author ized A udi dealer or au­
thor ized Audi Se rvice Facility to have the ma l­
f u nction co rrected.
E£-ij St eering lock: System fault! Plea se contact
deal er.
There is a malfunction in the electronic steering
lock.
D rive to an a uthorized Audi dea le r or a uthorized
Audi Service Facility immediately to have the
malfunct ion corrected.
@ Tips
If the . or Erj indicato r light on ly stays on
for a short time, you may continue driv ing.
All wheel drive (quattro)
Applies to vehicles: with all wheel drive
In oil wheel drive, oil four wheels ore powered .
General information
In a ll w heel d rive, the d rivi ng power is divided be­
tween a ll four wheels . This happens au tomatical-
156
ly depending on yo ur driv ing behavior as we ll as
the cur rent road conditions . Refer to
Q page 151.
The all whee l dr ive concep t is designed fo r high
engine power. Yo ur vehicle is except ion ally pow­
erf ul and has excellent drivin g charac teristics
both un der normal driving conditions and on
snow and ice . Always read and follow safety pre ­
cautions
c:> .&, .
Winter tires
By using all whee l dr ive, your ve hicle has goo d
f orward motion wi th standard tires in w inte r con ­
ditions . However, in winte r we recommend using
winter or all-season tires on all four wheels, be­
cause this will improve the brak ing effect
c:> page 206, Winter tires .
Snow chains
If there are snow chain laws, snow chains m ust
also be used o n veh icles with all wheel drive
c:> page 206, Snow chains.
Replacing tires
Fo r vehicles with all wheel drive, on ly wheels with
t h e same ro lli ng circ umfe rence sho uld be used .
Avoid whee ls with different t read depths
Q page 198 , New tires or wheels .
A WARNING
-Also, in vehicles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let t he increased
safety prov ided tempt you in to taking r isks,
because this inc reases t he risk of an acc i­
dent.
- The braking ab ility o f your vehicle is limited
t o th e trac tion of th e wh eels. I n this way, it
is no t differe nt from a two wheel drive vehi ­
cle. Do no t be tempte d to accelerate to a
hi gh speed when the ro ad is slip pery this in­
creases the risk of an accident .
- N ote tha t on wet s tree ts, the front wheels
can " hydrop lane" i f driv ing at spee ds tha t
are too high. Unlike front wheel drive
veh icles, t he engine does not
rev higher sud­
de nly when t he vehicle begins hydroplan ing.
For this reason, pay attention to the road
