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.

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

Winter tires
By using all whee l dr ive, your ve hicle has goo d

A WARNING
-Also, in vehicles with all wheel drive, adapt

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace
ment parts.
.,.New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,.Use tires of the same construc
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels .
198
.,.Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original equipment tires. If
you would like to use different
tires, please note that the tires may perform differently even if
they are the same size ¢
,&.
.,. If you would like to equip your
vehicle with a tire/rim combina
tion that is different from what
was installed at the factory, con
sult with an authorized Audi dealer or authorized Audi Service
Facility before making a pur
chase ¢&, .
If the spare tire is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire tem
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so that the
drive system is not damaged by .,.
Wheels
and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi
cation, refer to ¢
page 214, After changing a
wheel .
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 201.
The effectiveness of winter tires is reduced great
ly when the tread is worn down to a depth of
0 .157 inch (4 mm). The character istics of winter
tires also decrease greatly as the tire ages, re
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per
mitted speed for your tires. This cou ld cause
the tires to heat up too much. This increases
206
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where winter tires are required, only
winter tires w ith the ~ symbol may be per
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer or author
ized Audi Service Facility to see if you may use
snow chains.
The snow chains must have
low-profile links and
must not be thicker than 0.53 inch (13.5 mm),
including the lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.
