Introduction
App lies to vehicles: with Audi drive select
Drive select provides the possib ility to exper i­
e nce diffe ren t types of vehi cle sett ings in o ne
ve hicl e. For ins tance, us ing t he three
Com­
fort , Auto and Dynamic modes, the driver can
switch from a sporty to a comfortab le drivi ng
mode with the press of a b utton.
A ddit ionally, in veh icles wi th MM I*, the vehi ­
cle setup for
Individual* mode can be c us­
tom ized by you . This makes it possib le to
comb ine settings such as a sporty engine tun ­
ing with comfortable steering.
A WARNING
Improper use of the A udi drive select can
cause collisions , ot her acc idents and se ri­
ous pe rsonal injury .
Description
Applies to vehicles: with Audi drive select
The vehicle setup in each mode depends on
the veh icle's features . However, the engin e,
automa tic t ransmissio n* and steer ing are al­
ways involved.
-
Engine and automatic transmission*
Depending on the mode , the e ngine and the
automatic t ransm ission respond quicke r or i n
a mo re ba la nced manne r to a cce le rator pedal
move ments. In t he sporty dynam ic mode, the
a utom atic t ra nsm ission shifts at h igher R PMs.
Steering
The stee ring adapts in terms of stee ring effort
and st eering ra tios . Ind ir e ct steer ing that
moves easi ly, l ike the stee ring in comfort
mode, is bes t su ite d to long dr ives on a high­
way. In co ntr ast, dynam ic mo de p rov ides
sporty, direct steerin g.
Th e fo llow ing applies to vehicl es with dynam ic
s teer ing*: the stee ring rati o changes based on
ve hicl e spee d in order to main ta in op timum stee
ring effort for the drive r at all times . This
sets the stee ring to be less sens itive 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 minima l as poss ible when the drive r is
mane uveri ng the veh icle . At low and ave rage
spe eds, dynamic steering add itiona lly pro­
vides more responsive stee ring pe rforma nce.
Adaptive dampers*
The adaptive dampers* use se nsors to record
i nforma tion regard ing st eer ing movements,
braking and acceleration o perations by the
drive r, road surfac e, d riv ing speed, and load.
T his makes it poss ible to adapt damp ing to
t h e dr iving si tua tion v irtu ally in real t ime.
Dr ive sele ct also makes i t possib le to sa tisfy
t h e desi re fo r spo rty suspension ( Dynamic)
and comfortab le suspension (Comfort) with ­
o ut giving up ba lanced tuning (Auto) .
Sport differential*
As a compone nt of t he all whee l dr ive sys tem
(quat tro)
~ page 185, t he spo rt differential *
dist ributes the driving power to the rear ax le
depen ding on the sit uat io n. The distrib ution
of power var ies depending on the mode se­
lected. The goal is a high level of agility and
ability to accelerate on curves . T he ve hicle is
very res pons ive to steering .
Audi adaptive crui se control*
The behav ior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
t h e drive select mode. Adaptive cr uise control
also responds to the driv ing behavior of the
vehicle ahead in a mo re conservative o r spo rty
man ner.
Engine sound*
The sound of the eng ine is adapted to these­
lected mode and ranges from subtle to sporty.
(!) Tips
- In s ome models, the maximum vehicle
spee d can only be reached in the
Auto
and Dynamic modes.

-Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
-All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­ backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace-
Airbag system 151
ment parts designed and approved espe­
cially for your Audi model version. Re­ placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/per-
ch lorate. When the vehicle or parts of the
restraint system including airbag modules
safety belts with pretensioners are scrap­
ped , all applicable laws and regulations
must be observed. Your authorized Audi
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

A WARNING 1= ~
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 brak ing effect.
([) 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 switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive th rough safely.
- Avoid dr iving through sa lt 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 an environmentally sound manner.
11-Always use lead -free gaso line¢ page 201,
Fuel supply .
"'"Never run the tank down all the way to emp­
ty.
11-Never put too much motor oil in your engine
¢ page 211, ~ Adding engine oil .
11-Never try to push -or tow -start your veh icle .
The catalytic converter is an efficient "clean­ up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere .
Drivin g and en vironm ent 18 9
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert­
er and proper f unct ion ing of the engine.
A WARNING
- The temperature of the exhaust system
is high, both when driving and after stop­
ping the eng ine.
- Never touch the exhaust tail pipes once
they have become hot. This could result in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, br ush,
fue l spill or other material wh ich can
cause a fire .
- Do not apply additional undercoating or
ru stp roof ing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ve rter or heat shield s. Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just o ne tank filling with
leaded fuel w ill already ser iously de­
grade the performance of the catalytic
converter .
- Do not exceed the cor rect engine oil level
¢ page 211.
-Do not drive until the f ue l t ank becomes
comple tely empty . The engine co uld m is ­
fire . Unburned fuel could also get into
the exhaust system and this co uld cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is mov ing.
- Do not continue to operate your vehicle
under these conditions, as othe rwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement.

232 Tires and wheels
to determine how this re­duces the available cargo
and luggage load capacity of
your vehicle.
.,.Check the tire sidewall
(¢ page 233, fig. 172) to de­
termine the designated load rating for a specific tire.
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv·
ing style.
Fig. 170 Tire tread: tread wear indicators (TWI)
_____ ___,.J)
Fig. 171 Rotating tires for more even wear
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c.> fig. 170 running across the tread. Depend·
ing on the make , there will be six to eight of
them evenly placed around the tire. M ar ks on
the tire sidewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear indicators. Worn tires must be replaced. Different
figures may apply in other countries
¢& .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden tire blow-out. For this
reason, tire pressure must be checked at least
once a month
¢ page 228.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service intervals outlined in your
Maintenance and Warranty Booklet .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals.
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pa red to all wheel drive (quattro).
- Please rotate tires as shown¢
fig. 171.
- Extra care must be taken when rotating di-
rection-specific tires ¢
page 249.
Wheel balancing
The wheels on new vehicles are balanced .
However, various situations during everyday
driving can cause them to become unbal­
anced, resulting in vibrations you can usually
feel through the steering wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed. .,.
