Z\ WARNING
— Only adjust the front seat when the vehicle
is stationary. Otherwise, this increases the
risk of an accident
— The power front seats can also be adjusted

when the ignition is switched off. For this

46

reason, children should never be left unat-
tended in the vehicle because they could be
injured.
— Exercise caution when adjusting the seat
height. Unsupervised or careless seat adjust-
ment can pinch fingers or hands causing in-
juries.
— The front seat backrests must not be re-
clined too far back when driving, because
this impairs the effectiveness of the safety
belts and airbag system, which increases the
risk of injury.
—To minimize the risk of injury during sudden
braking or a collision, the driver and the
front passenger must not drive or ride with
the backrest in the reclined position. The
safety belts and airbag system can only pro-
vide the greatest protection possible when
the backrests are in the upright position and
the safety belts are worn correctly. The more
a backrest is reclined, the greater the risk of
injury due to an incorrect seating position
and safety belt position.
Multifunction button
Applies to: vehicles with multifunction button


You can adjust the side bolsters using the multi-
function button.
> If you turn the multifunction button @
=> page 46, fig. 48 to the left or right, the side
bolsters on the seat backrests will increase or
decrease the lateral support.
G) Tips
The air in the side bolsters* is released as
soon as the driver's door opens. This makes is
possible to enter and exit the vehicle more
comfortably. As soon as you start driving the
vehicle, the side bolsters fill.

Please remember - safety first!
The individual 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 information,
tips, instructions and warnings that you need to
read and observe for your own safety, the safety
of your passengers and others. We have summar-
ized here what you need to know about safety
belts, airbags, child restraints as well as child
safety. Your 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 information in this section applies to all
model versions of your vehicle. Some of the fea-
tures described in this sections may be standard
equipment on some models, or may be optional
equipment on others. If you are not sure, ask
your authorized Audi dealer.

ZA WARNING
— Always make sure that you follow the in-
structions and heed the WARNINGS in this
Manual. It is in your interest and in the in-
terest of your passengers.
— Always keep the complete Owner's Litera-
ture in your Audi when you lend or sell your
vehicle so that this important information
will always be available to the driver and
passengers.
— Always keep the Owner's literature handy so
that you can find it easily if you have ques-
tions.

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,
before driving always:
> Make sure that all lights and signals are operat-
ing correctly.
> Make sure that the tire pressure is correct.
> Make sure that all windows are clean and afford
good visibility to the outside.
> Secure all luggage and other items carefully
= page 50, > page 49.
> Make sure that nothing can interfere with the
pedals.
> Adjust seat and mirrors correctly for your
height.
> Make sure to use the right child restraint cor-
rectly to protect children > page 210, Child
safety.
> Sit properly in your seat and make sure that
your passenger do the same © page 46, Front
seats.
> Fasten your safety belt and wear it properly. Al-
so instruct your passenger to fasten his safety
belt properly > page 182.
What impairs driving safety?
Safe driving is directly 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.
The driver is responsible for the safety of the ve-
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
vehicle increase and you also become a hazard to
everyone else on the road > /\. Therefore:
> Do not let yourself be distracted by passenger
or by using a cellular telephone.
> NEVER drive when your driving ability is im-
paired (by medications, alcohol, drugs, etc.).
> Observe all traffic laws, rules of the road and
speed limits and plain common sense.
> ALWAYS adjust your speed to road, traffic and
weather conditions.

Airbag system


the vehicle battery with a pyrotechnic circuit
interrupter.
— Work on the pyrotechnic circuit interrupter
must only be performed by a qualified
technicians who have the experience, in-
formation and special tools necessary to
perform the work safely.
— If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions

must be followed.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs ina crash. For example, using tire-rim
combinations not approved by Audi, lowering the
vehicle, changing the stiffness of the suspension,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit. Some suspension changes
can, for example, increase the force levels meas-
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy-
ing when it should.

Z\ WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in-
crease the risk of serious personal injury ina
crash.
— Never install suspension components that
do not have the same performance charac-
teristics as the components originally instal-
led on your vehicle.
— Never use tire-rim combinations that have
not been approved by Audi.

Knee airbags
Pye al) CooL Aide}
The knee airbag system can provide supplemen-
tal protection to properly restrained front seat
occupants.

Fig. 159 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel > fig. 159, 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 198, 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
position in a frontal collision so that the airbags
can provide 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. This is why you should al-
ways wear your safety belt, not just because the
law requires you to do so > page 182, General
notes.

The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re-
gardless of the remaining tread.
@) 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.
G) 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 win-
ter tires with the “ symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> 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
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized 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.

ZA\ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.

CG) Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.
— Using snow chains that add more than 0.53
in (13,5 mm) of height can severely damage
the wheel housings and other vehicle com-
ponents.
@) Tips
When using snow chains, it may be advisable
to limit the ESC > page 87.
ee cil med
Applies to: vehicles with low-profile tires
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 agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 250.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an
authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
