Intellig ent Technology
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all whee l drive, the dr iving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as we ll as
the cur rent road conditions . A lso see ¢
page 89 .
The all whee l dr ive concept is des igned for high
engine power. Yo ur vehicle is except iona lly pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­ cautions
q .&, .
Winter ti res
By using all whee l drive, your veh icle has good
forward motion w ith standard tires in winter con­
ditions . However, using winter or all season tires
on
all four wheels in the winter is recommended,
because th is w ill improve the
braking effect.
Snow chains
If there a re snow chain laws, snow cha ins m ust
also be used on ve hicles with all wheel drive
¢ page 181, Snow chains .
Replacing tires
For vehicle s wi th a ll wheel d rive, o nly wheels wi th
the same roll ing ci rcumfe rence sho uld be used.
Avoid using tires with di fferen t tread depths
¢ page 173, New tires or wheels.
A WARNING
- Also, in vehicles with all whee l drive, adapt
your driving style to the current road and traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the trac tion of the wheels. I n this way, it
is not different from a two w heel d rive vehi ­
cle. Do no t be tempte d to accelerate to a
h igh speed when the ro ad is s lippery, be -
cause t his increases t he risk of an acci den t. ...,

Airbag system
service action is entered in your Audi War­
ranty
& Maintenance book let under AIRBAG
REPLACEMENT RECORD.
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules safe­
ty belts with pretens ioners are scrapped, al l
applicable laws and regulat ions must be ob­
served. Your authorized Audi dealer is familiar
with these requ irements and we recommend
that you have your dealer perform this service
for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For examp le, using t ire-rim
combinations not approved by Audi, lower ing the
veh icle, changing the stiffness of the suspens ion,
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 .
A 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 in jury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­
led on your veh icle .
128
.
-Never use tire-rim combinations that have
not been approved by Aud i.
A WARNING
Items stored between the safety belt buckle
and the center conso le can cause the sensors
in the buckle to send the wrong information
to the electronic control module and prevent
the Advanced A irbag System from wo rking
p roperly.
-Always make sure that nothing can interfere
w ith the safety belt buckles and that they
are not obstructed.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 116 Sid e a irbag locatio n in the dr ive r's seat
The side airbags are located in the s ides of the
front seat backrests
~ fig . 116 facing the doors .
They are identified by the word "AIRBAG ".
The side airbag system basically consists of:
-the electronic control module and external side
impact sensors
- the two airbags located in the sides of the front
backrests
- the airbag warning light in the instrument clus-
ter.
The airbag system is mon itored electron ically to
make certain that it is functioni ng properly at a ll
times. Each time you turn on the ignition, the air ­
bag system indicator light will come on for a few
seconds (self diagnostics). .,,_

"' a) ID
The windshield washer fluid reservoir W contains
the cleaning solution for the windshield and the rear w indow
q page 158, fig . 137,. The reservoir
capacity can be found in
qpage 210.
To reduce the risk of lime scale deposits on the
spray nozzles, use clean water with low amounts
of calc ium . Always add window cleaner to the wa­
ter. When the outside temperatures a re cold, an
anti-freezing agent should be added to the water
so that it does not freeze.
- The concent ration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective climate. A con­
cent ration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­
tives to the washer fluid.
- Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint .
Checking and Filling
Service interval display
The service interval display detects when your ve­
hicle is due for service .
The service interval display works in two stages:
-Inspection or oil change reminder : after a cer-
tain distance is driven, a message appears in
t he instrument cluster display every time the
ignition is switched on. The remaining distance
or time is displayed br iefly.
- Inspection or oil change due: if your vehicle
has reached an inspection or oil change interval
or both intervals at the same time, the mes­
sage
Inspection due! or Oil change due! or Oil

cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage
Fig. 145 Tire profile : treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dea ler
or authorized Audi Service Facili-
l ) Obey any applicable regulations in your
country.
Wheels
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running d irec­
tion
i:::> fig. 145. The letters "TWI "
or triang les on the tire sidewall
indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l ) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
i:::> .&..
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires, install the tires from the rear axle ..,.

Wheels
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switch ing between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c:::> page 184. The tire pressure moni­
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c:::> page 176, fig. 147.
Tire tread circumference and vibration character­ istics can change and cause a t ire pressure warn­
ing if:
- the tire pressure in one or more tires is too low
- the tire has structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored
