- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lling
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the

Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack­
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air­
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you m ust take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air­
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .
T he cont ro l unit "dec ides " w het her to fire
the front airbags based on the information
received from the crash senso rs . The contro l
unit a lso "decides" whethe r the safety be lt
pretensioners should be activated . -
An Advanced A irbag w ith gas generator and
cont ro l valve for the d river inside the steer­
ing wheel h ub.
- An Advanced A irbag with gas ge nerator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight-sensing mat under the up ho lstery
pad ding of the front passenger seat cushion
that measures the total weight on the seat.
The informat ion registered is sent continu­
ously to the electronic contro l unit to regu­
late deployment of the front Advanced Air­ bag on the passenger side .
- An airbag monitor ing system and i ndicator

formation registered is sent cont inuously to
t he ele ctr onic cont ro l uni t to regula te de­
p loyment o f the front Advance d Airbags .
- The

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light¢
page 16
comes when the vehicle is being used,
have the system inspected immediately
by your authori zed Audi dealer. It is pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should .
A WARNING
If the front airbag inflates, a child without
a child restraint, in a rearward-facing child
safety seat or in a forward-facing child re­
straint that has not been properly installed
will be seriously injured and can be killed.
- Even though your vehicle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, always ride on the back seat properly restrained for their
age and size.
- Always install forward or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not appear and stay on, imme­
diately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your au­
thorized Audi dealer.
- A tight tether or other strap on a rear­
ward-facing child restraint attached to
the front passenger seat can put too
much pressure on the weight-sensing
-
mat in the seat and register more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adult were on the seat and deploy the Advanced Airbag when it
must be suppressed causing serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re­
straint on the front passenger seat, al­
ways move the seat into its rearmost po­
sition in the seat's fore and aft adjust­
ment range, as far away from the airbag
as possible. The backrest must be adjust­
ed to an upright position. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when­
ever the ignition is switched on .
A WARNING
-
-
-If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, make sure the
adult is properly seated and restrained at
one of the rear seating positions.
- Have the airbag system inspected by
your authorized Audi dealer before trans­
porting anyone on the front passenger
seat.
(D Tips
If the weight-sensing mat in the front pas­
senger seat detects an empty seat, the
front airbag on the passenger side will be
turned off, and
PASSENGER AIR BAG OFF
will stay on.
Repair , care and disposal of the airbags
Par ts of the airbag system are ins talled at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision. .,..

172 Airbag system
dealer is familiar with these requirements
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 Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion 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 exam­ ple, increase the force levels measured 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 meas­
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not.
If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
= -
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­
fere with 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. 169 Side a irbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests¢
fig. 169 and the rear
backrest* 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 and the two airbags* located
in the rear backrest
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly ..,.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
ping and improves driving stability. ESC de­
tects critical s ituations such as the vehicle
Intelligent technology 197
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy­
namic steering*, hill descent assist and selec­
tive wheel torque control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomatically when conditions have returned to
normal.

There must be however sufficient ground ad ­
hesion . The hill descent assist can
not do its
job if the incl ine is icy or if the incline ground
is loose ¢,&..
The system does not work at speeds between
19 and 37 mph (30 and 60 km/h). The system
is then in the ready-mode. The diode in the
button will come on . The system automatical­
ly switched
off when you drive faster than 37
mph (60 km/h) . The diode will go out in this
case.
Active control at a specific speed up to approx­
imately 19 mph (30 km/h) w ill appear in the
instrument cluster display ¢
fig. 188. Two
dashes' '-- " w ill appear in the ready mode.
Hill descent assist is automatica lly act ivated
under the following cond itions:
- the diode in the button illuminates,
- vehicle speed is be low approximate ly
19 mph (30 km/h)
- the incline is 10%.
A WARNING
-Always adapt your speed to the weather,
road and traffic conditions . Do not let
the increased safety provided tempt you
into taking r isks.
- The hill descent assist system cannot
overcome the laws of physics. Your driv­
ing style must always be adapted to the
current road and traffic conditions.
- The hill descent assist may not be able to
hold your vehicle at a constant speed un­
der all condit ions wh ile driving on an in­
cl ine (for example if ground under the
vehicle is loose).
Brake system
Operating conditions and driving habits
The brakes on today's automobiles are st ill
subject to wear, depending largely on operat­
ing conditions and dr iv ing habits ¢& . On
veh icles that are e ither driven mostly in stop­
and-go city traffic o r are driven hard, the
brake pads should be checked by your author- ized Audi dealer more often
than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine. This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont inuously. Pump the brakes at inter­
vals .
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moisture or road salt
Under certain conditions, for example, when
driving through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing cond itions ice) on the brake pads. A
few careful brake applications should dry
off
the brake pads or remove any ice coatings .
When you are driving at higher speeds with
the windshield wipers on, the brake pads will
briefly touch the brake discs in regular inter ­
vals so as to improve reaction time when brak­
ing on wet surfaces. You, the driver, will not
notice anything.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered
road and the b rakes are not used. Here too,
you should clean
off accumulated sa lt coating
from brake discs and pads with a few careful
applications of the brake ¢& .
Corrosion
The re may be a tendency for dirt to build up
o n the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with littl e use of the
brakes.
If the brakes a re not used frequently, o r if cor­
rosion has formed on the discs, it is adv isable
to clean
off the pads and discs by braking
firmly a few times from a modera tely high
speed ¢£ .

Selective catalytic
reduction
General information
Applies to vehicles: wit h diese l en gi ne
On vehicles with selective catalytic reduction,
an urea solution (Ad Blue) is injected into the
exhaust system before a nitrogen oxide cata­
lytic converter to reduce nitrogen emissions.
The Ad Blue is stored in a separate tank in the
vehicle . The Ad Blue usage accounts for ap­
proximately 0.5% to 1.2% of the diesel fuel
that is used.
You must refill the Ad Blue or have it refilled
by your authorized Audi dealer or qualified
workshop as soon as the AdBlue refill mes­ sage appears in the instrument cluster
c;,page229.
A WARNING
Failure to heed Ad Blue refill information in
the instrument cluster can prevent the ve­
hicle from being started and driven. If the
vehicle cannot be driven and an emergency
arises, persona l inju ry can occur.
- Always have the Ad Blue tank refilled well
before the tank ru ns dry.
@ Tips
-The instrument cluster display indicates
the distance remaining that can be driv­
en
