_& WARNING
-To reduce the risk of an accident, only adjust
the seat when the veh icle is stationary.
- Exercise caution when adjusting the seat
height . Adjusting the seat care lessly or
without checking can pinch hands and fin ­
gers .
- For safety reasons, the seat backrests must
always be locked while driving .
- Never drive with a safety belt through the
openings in the backrest . Otherw ise the
backrest could fold forward wh ile driving
and cause an accident.

Safe driving Basics
Safe driving habits
Please remember -safety first!
The individua l safety features of your vehicle can
work together as a system to help protect you
and your passengers in a wide range of accidents.
These features cannot work as a system if they
are not always correctly adjusted and correctly
used .
This chapter contains important informat ion,

safety. Yo ur safety is for us priority number 1. Al­
ways observe the information and warnings in
this section - for your own safety as well as that
of your passengers.
The informa tion in t his sect ion app lies to all
model versions of your vehicle. Some of the fea ­
tures described in t his sections may be standard
eq uipment on some models, or may be optional
equ ipment on others. If you are not sure, ask
your author ized Audi dealer.
A WARNING

Important things to do before driving
Safety is everybody 's job ! Vehicle and occupant
safety always depends on the informed and care­
ful driver .
For your safety and the safety of your passenger,
b efor e driving alw ay s:
.. Make sure that a ll lights and s ignals are operat­
ing correctly.
.. Make sure tha t the tire pressure is correct .
.. Make sure that all windows are clean and afford
good vis ibility to the outs ide .
.. Secure all luggage and othe r items ca refully

What impairs driving safety?
Safe driving is dire ctly related to the condition of
the vehicle, the driver as well as the driver's abili­
ty to concentrate on the road without being dis ­
tracted.
T he dr iver is responsib le for the sa fe ty of the ve ­
hicle and a ll of its occupants. If your ability to
drive is impai red, safety risks for everybody in the
vehicl e inc rease and you a lso become a hazard to
everyone else on the road
¢ A_ . Therefore:
.. Do not let yourse lf be distracted by passenge r
or by using a ce llular telephone .
.. NEVER drive when your driving ability is im ­
pa ired (by med ications, alcohol, drugs, etc.) .
.. Observe all traffic laws, rules of the road and
speed lim its and plain common sense .
.. ALWAYS adjust your speed to road, traffic and
weather conditions .

Airbag system
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants .
Fig. 165 Driver's k nee a irbag
The driver knee airbag is in the instrument panel
underneath the steering
wheel ¢ fig. 165, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
¢ page 203, More important things to know
about front airbags.
In addition to their normal safety function, safe­
ty belts help keep the driver or front passenger in
posi tion in a frontal collision so that the airbags
can prov ide supplemental protection .
The airbag system is not a substitute for your safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle. Always re­
member that the airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly . T his is why you should
always wear your safety belt, not just because
the law requires yo u to do so ¢
page 187, Gener­
al notes.
210
Remember too, airbags will deploy only once and
on ly in certain kinds of accidents -your safety
belts are always there to offer protection in those
accidents in which airbags are not supposed to
deploy or when they have already deployed, for
example when your vehicle strikes or is struck by
another after the first collision .
This is just one of the reasons why an airbag is
not a substitute for the safety belt . The airbag
system works most effectively when used with
the safety belts. Therefore, always wear your
safety belts correctly.
It is important to remember that while the sup­
plemental knee airbag system is designed to re­
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising and minor
abras ions and friction burns can also occur when
an airbag inflates.
The knee airbag system basically consists of:
-The electronic control module
-Two inflatable airbags (airbag and gas genera-
tor), one for the driver and one for the front
passenger
- The airbag warning light in the instrument clus-
ter
The knee airbag system will not deploy:
-when the ignition is switched off
- in frontal collisions when the decelerat ion
measured by the control unit is too low
-in side collisions
-in rear-end collisions
-in rollovers
-in the event of a system malfunction (warning/
ind icator light is on)
¢ page 14 .
.&, WARNING
-Safety belts and the airbag system can only
provide protection when occupants are in
the proper seating position
¢page 203 .
-If the airbag ind icator light ¢ page 14
comes when the vehicle is being used, have
the system inspected immediately by your
authorized Audi dealer.
It is possible that
the airbag will inflate when it is not sup ­
posed to, or will not inflate when it should.

rims yourself, because this increases the risk
of an accident.
Winter tires
Winter tires significantly improve the vehicle 's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern), summer tires provide less 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
9 .&, in
General information on page 244.
An author­
ized Audi dea ler or authorized Audi Service Fa­
cility can inform you about the maximum per­
mitt ed sp eed for your tires .
.. Check the tire pressure after installing wheels
9page 254.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1S7 in (4 mm) . The chara cteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread .
@.l For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter tires . Please note that in some coun­
tries where w inter tire s are required, only
w int er tires with
the£ symbol may be per­
mitted.
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking.
Wheels
.. Only install snow chains on the front wheels.
This applies a lso to vehicles with all wheel
drive* .
.. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
.. Note the maximum speed of 30 mph (SO km/
h) . Note the local regulations .
Use of snow chains is only permitted with certa in
rim/tire comb inat 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 .
You must remove the snow chains on roads with­
out snow . Otherwise, you could impair driving
ability and damage the tires .
.8, WARNING
Using incorrect snow chains or install ing snow
chains inc orrectly can resu lt in loss of veh icle
control, which increases the risk of an acci­
dent.
(W) Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them. Remove the wheel covers*
first. Use coated snow chains.
- Using snow chains that add more than O.S3
in (13,S mm) of height can severe ly damage
the whee l housings and other vehicle com ­
ponents .
(D Tips
When using snow chains, it may be usefu l to
switch on sport mode
~ page 87.
Low-profile tires
App lies to: vehicles wi th low- pro fil e tir es
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls .
This results in an ag ile driving style . However, it
may reduce the level of comfort and increase
r oad noise when driving on roads in poor condi-
tion.
