Other things that can affect Advanced
Airbag performance
Changing the vehicle 's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For example, using t ire-rim
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspension,
including the spr ings, suspension s truts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control un it. Some suspension changes
can, for example, increase the force leve ls meas
ured by the sensors and make the airbag system
deploy in c rashes in which it wo uld not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and preve nt the airbag from deploy
i n g when i t should .
A WARNING
Changing the vehicle's s uspension including
use of unapproved ti re -rim comb inations can
change Advanced A irbag pe rformance and in
crease t he risk of serious persona l injury in a
crash.
- Never install suspension components that do not have the same performance charac
teristics as the components or iginally insta l
led on your veh icle .
- Never use tire-rim combinations that have
not been approved by Audi .

A WARNING
Items stored between the safety be lt b uckle
and the center console can cause the sensors i n the buckle to send the wrong informat ion
to the electronic control module a nd prevent
the Adva nced Airbag System from wor king
properly .
- Always ma ke sure that nothing can interfere
w it h the safe ty belt bu ckles an d that they
are no t obstr ucted.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
F ig. 169 S ide ai rbag locat io n in th e dr ive r's seat
The side airbags are located in the sides of the
fron t seat backrests ~
fig. 169 and the rear back
res t* fa cing the doors. They are identified by the
word "AIRBA G".
The side airbag sy stem bas ically consi st s of :
-the electron ic control module and external side
impact sensors
- the two airbags located in the s ides of the front
backrests and the two airbags* located in the
rear backrest
- the airbag warning light in the instrument clus-
ter.
The airbag system is monitored e lectronically to
make certain that it is functioning properly at all
times. Each time you turn on the ignit ion, the air
bag system indicator light w ill come on for a few
seconds (self d iagnost ics) .

wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four whee ls 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.
- When installing a factory-supplied roof rack
system on the roof railing, the ESC will
adapt itself to a different center of gravity.
ESC turns on automatically when you start the engine.

- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground

H ill descent assist brakes all four wheels auto
mat ica lly in o rder to lim it speed when driv ing ei
ther fo rward or reverse on hills with a grade up to
approximately 50%.
When the h ill descent assist is on, the current
d riving speed, when your vehicle entered the in
cline is maintained.
It is only possible to switch
on the ass ist when d riving slower than 37 mph
(60 km/h). The assist works between app rox i
mately 2 and 19 mp h (4 and 30 km/h). The driver
can increase or decrease the vehicle speed within
these limits by depressing the acce lerator or
brake pedal In addition , vehicle steerability is in
creased due to the braking distribution when
:0 driving in reverse .

Hill descent assist is automatically activated un
der the fo llowing conditions:
- the diode in the button i lluminates,
- veh icle speed is below approximately 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 in
creased safety provided tempt you into tak ing risks.
- The hill descent assist system cannot over
come the laws of physics . Your driving style
must always be adapted to the current road
and traffic conditions.
- The hill descent assist may not be ab le to
hold your vehicle at a constant speed under
all conditions w hile driving on an incl ine (for
example if ground under the vehicle is loose) .
Braking
What affects broking efficiency?
New brake p ad s
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢ &. .,,.
