Audi drive select Driving settings
Introduction
App lies to vehicles: w it h drive se lect
Aud i drive select provides the possibility to ex­
perience different types of veh icle sett ings in
one veh icle. For instance, using the three
C o mfort , Au to and Dyna mic modes, the driv­
er can switch from a sporty to a comfortab le
driving mode with the press of a button.
Addit ionally, in vehicles with MM I*, the vehi ­
cle setup for
Indi vidual * mode can be cus­
tomized by you. This makes it possib le to
combine settings such as a sporty engine tun­
ing with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury.
Description
Ap plies to vehicles: w it h drive se lect
The vehicle setup in each mode depends on
the vehicle's features. However, the engine,
automatic t ransmission* and steering are al­
ways involved.
.
Engine and automatic transmi ssio n*
Depending on the mode, the engine and the
automatic transmission respond quicker or in
a more ba lanced manner to acce lerator pedal
movements. In the sporty dynamic mode, the
automatic t ransmission shifts at h igher R PMs .
Steering
The steering adapts in terms of steering effort
and steering ratios . Indirect steer ing that
moves eas ily, like the stee ring in comfort
mode, is best su ited to long dr ives on a high ­
way. In contrast, dynam ic mode prov ides
sporty, di rect steering .
The follow ing applies to vehicles with dynam ic
steer ing*: the stee ring ratio changes based on
ve hicle speed in order to maintain optimum
Aud i dri ve sel ect 109
steering effort for the drive r at all times. This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steer ing
is more d irect in order to keep the steering ef­
fort as minimal as poss ible when the driver is
maneuveri ng the vehicle . At low and average
speeds, dynamic steering addit iona lly pro­
vides more responsive stee ring pe rformance.
Adapt ive dampers*
The adaptive dampers* use sensors to record
i nformation regarding steering movements,
braking and acceleration ope rations by the
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the d riving situation v irtually i n rea l time.
Audi drive select also makes it possible to sat­ isfy the desire for sporty s uspension (Dynam­
ic) and comfortable suspension (Comfort)
without giv ing up ba lanced tuning (Auto).
Sport diff ere ntial *
As a component of the all whee l dr ive system
(quattro ®)
q page 190, the sport differential*
distributes the driving power to the rear ax le
depending on the situation . The distribution
of power var ies depending on the mode se­
lected. The goal is a high level of agility and
ability to accelerate on curves . The ve hicle is
very respons ive to steering .
Adaptive crui se control *
The behav ior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise control
also responds to the driv ing behavior of the
vehicle ahead in a mo re conservative or spo rty
manner .
Engine sound*
The sound of the eng ine is adapted to the se­
lected mode and ranges from subtle to sporty.
0) Tips
- In some models, the maximum vehicle
speed can only be reached in the
Auto
and D ynamic modes.

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-r im 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
d river 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.
.&_ 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
Airbag system 157
characteristics as the components origi­
nally installed on your vehicle .
- Never use tire-rim combinations that
have not been approved by Audi.
.&_ 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.
Knee airbags
Description of knee airbags
Applies to vehicles: wit h knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 144 Driver 's knee airbag
The driver knee airbag is in the instrument
panel underneath the steering wheel
Q fig . 144, the knee 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 up­
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also deploy in frontal collisions when the de­ ployment threshold stored in the control unit

194 Driving and en vironm ent
8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
CD Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in on environmentally sound manner.
,,. Always use lead-free gasoli ne¢ page 211,
Fuel supply .
,,. Never run the tank down a ll the way to
empty.
,,. Never put too much motor oil in your en-
gine ¢
page 221, "t':::r. Adding engine oil.
,,. Never t ry to push- o r tow-start your veh icle.
The catalytic converter is an effic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the polluta nts in the exhaust gas be­
fore they are released into the atmosphe re. The exclusive
use of unleaded f uel is critica lly
important for the life of the catalytic convert­
er and proper funct ion ing of the eng ine .
A WARNING
= -
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or heat shields. Dur ing driv ing, the
substance used for under coa ting co uld
overhea t and cause a fire.
CD Note
- Be aware that just o ne tank filling with
leaded fu el w ill already ser io usly de ­
gr ad e the per form ance o f the catalytic
c onverte r.
- Do not ex ceed t he corre ct engine oil level
r:;!) page 2 21.
- Do not drive until the fuel tank be co m es
completely emp ty. The engine co uld mis­
fire . Unburned fuel could also get in to
the exhaust system and this co uld cause
the cata lytic converter to overheat .
- Do not turn off the igni tion whi le the ve ­
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalyt ic converte r. T his
co uld resu lt in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained p rope rly
