Applies to: vehicles with Audi drive select
Drive se lect makes it possible to experience dif­
fe rent types of vehicle settings in one vehicle.
The dr ive r can se lect
Comfort , Auto a nd Dynamic
modes in the I nfota inme nt system to switch be­
tween , fo r exa mple, a sporty and a co mfo rtable

makes it poss ible to comb ine settings su ch as a
sporty eng ine setting w ith smooth stee ring.
Descript ion
Applies to: vehicles with Audi drive select
The fo llow ing systems, among other things, are
i nfluenced by drive select:
Engine and automatic transmission
D epending on the mode, the en gine and auto­
mat ic transmission respond more quickly o r in a
mo re balanced ma nner to accelerator pe dal
movements . In the spo rty
Dynamic mode, the
transmission shifts at higher speed ranges.
Steering
The power s teering adapts. Ind irect s teer ing t hat
moves easi ly as in
comfort mode is espec ia lly
suited to long drives on highways . The
dynamic
mode p rovides sporty, d irect steering.
The fo llow ing applies to vehicles wi th dynam ic
steer ing* : the stee ring rat io chan ges base d on
ve hicle speed in or der to ma inta in optim um
steer ing effort for the drive r at all times. This
sets the steer ing to be less sensitive at higher
speeds i n order to prov ide improved vehicle con-
Assist
t ro l. At r educed spee ds, steeri ng is more direct in
o rder to kee p the steering effort as minima l as
poss ib le when the drive r is maneuvering t he vehi­
cle. Dynam ic steer ing* also p rovides more re­
spons ive steering performance at low and aver­
age speeds .
Suspension control*
The ada ptive dampers * use sensors to reco rd in ­
f ormat ion regard ing steering movements, b rak ­
ing and accele ration operations by the dr iver,
road s urface, driving speed, and load. This makes
it possible to adapt damping to the d riv in g situa­
t io n virtu ally in rea l ti me . Wi th drive select, you
can ad just th e adap tiv e dam pers to sporty

-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
- Work on the pyrotechnic circ uit interrupt ­
er 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 app licab le safety precautions
must be followed .
@) For the sake of the environment
Undeployed airbag modu les a nd pretension ­
ers might be classified as Perch lorate 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 and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
m iliar with these requi rements a nd we recom­
mend t hat you have you r 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 example, using tire-r im
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspens io n,
in clud ing the spr ings, suspens ion str uts, shock
absorbers et c. can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l 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 wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the fo rce levels meas ured by
the sensors and prevent the airbag from deploy­
in g when i t should .
Airbag sys tem
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 persona l injury in a
crash.
- Never install suspension components that
do not have the same pe rformance charac­
teristics as the components o rigina lly ins tal­
led on your vehicle.
- Never use tire-rim combinations t hat have
not been approved by Audi.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to prop erly restrained front sea t
occupants.

T he knee airbag offers add itiona l protection to
the driver's and passenge r's knees and uppe r and
lower thigh areas and supp lements the protec­
tion provided by the safety be lts .
