Audi drive select Driving settings
Introduction
Aud i drive select makes it possible to experi­
ence different types of vehicle settings in one
veh icle. The driver can select th ree
Comfort,
Auto
and Dynamic modes in the MMI to
switch between a sporty and a comfortable
driving mode.
You can also adjust the setting according to
your preferences in the
individual mode. For
examp le, you can combine settings such as a
sporty engine tuning with light steering.
Descript ion
The vehicle setup in each mode depends on
the vehicle's features. The engine, transmis­
sion, steering, reversible safety belt tension ­
ers and adaptive air suspension are always in­
volved .
Engine and transmission
Depending on the mode, the engine and the
transmission respond more quickly or in a
more balanced manner to accelerator pedal
movements. In the sporty dynamic mode, the
transmission sh ifts at higher RPMs.
Air suspension
The adaptive air suspension/adaptive air sus­
pension sport*
( Air suspension in the MMI) is
an electronically cont rolled air suspension and
damping system. They are adjusted depend­ ing on the selected driving mode, the driver's
steering, braking and acceleration input and
the road s urface, veh icle speed and load. A
sporty setting is generally used in vehicles
with adaptive air suspension sport *.
The vehicle clearance va ries depending on the
selected mode and the speed .
The highway setting is activated automatically
when you drive above 75 mph (120 km/h) for
mo re than 30 seconds in the
auto or dynamic
mode. The g round clearance is increased auto-
Audi drive select 103
matically if the speed drops below 44 mph
(70 km/h) for more than 120 seconds.
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect steering that
moves easily as in comfort mode is especially
s ui ted to long drives on a highway. In con­
trast, dynamic mode provides sporty, direct
steering.
T he following applies to vehicles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the driver at all times. This
sets the steering to be less sens itive at higher
speeds in order to provide improved vehicle
control.
Sport diffe rential*
As a component of the all whee l drive system
(quattro
® ) c> page 191, the Sport differen­
tial* distributes the driving power to the rear
axle depending on the situat ion. The dis tribu­
tion of power varies depending on the select­
ed mode, from balanced (comfort) to agile
(dynamic). The goal is a hig h level of agility
and ability to accelerate on curves. Th e vehi cle
is very responsive to steer ing.
Adaptive cruise control*
The behav ior when accelerating can be adjust
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control al­
so responds to the driving behavior of the ve­
hicle ahead in a more conserva tive or sporty
manner.
(D Note
- Make sure there is enough clearance
above and below the vehicle when park­
ing . The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load condi­
tions and changes to the driving modes,
w hich can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on-
ly tie the vehicle down at the running

Improperly worn safety belts
Incorrectly positioned safety belts can cause
severe injuries.
Wear ing safety be lts imprope rly can cause se ­
rio us inj ury or death. Safety be lts can on ly
wo rk when they are correct ly positioned on
the body. Improper seating positions reduce
the effect iveness of safety belts and will even
increase the r isk of injury and death by mov­
ing the safety belt to cr itical areas of the
body. Imprope r seat ing pos it ions also in­
crease the risk of serio us in jury and death
when an air bag deploys and str ikes a n occu­
pant who is not in the correct seating posi­
tion . A d river is responsib le for the sa fety of
all vehicle occupants and especially for chi l­
dren. Therefore:
~ Never permit anyone to ass ume an incorrect
sitting position in the veh icle w hile traveling

A WARNING
Imprope rly worn safety belts increase the
r isk of serious personal injury and death
whenever a veh icle is being used. -
Always make sure that all vehicle occu­
pants are co rrectly restrained and stay in
a correct seating position whenever the
veh icle is being used .

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 Stability
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 187
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
Ip.] in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffi<; and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a veh icle
on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

188 Intelligent technology
ESC includes and/or works together with the
anti-lock braking system (ABS), brake assist
system, anti-s lip regulat ion (ASR), e lectronic
d ifferential lock ( EDL), dynamic steering* and
e lectronic interaxle differentia l lock*. ESC is
switched on all the time. I n certa in s ituations
when you need less tract io n, you ca n sw itch
off ASR by pressi ng the button above
~ page 189, fig. 167 the se lector lever. Be
sure to sw itch ASR on ag ain when you no lon­
ger need less trac tion.
Anti -lock braking system (ABS)
ABS prevents t he wheels from locking up
when braking. The veh icle can still be st eered
even d uring ha rd b rak ing . Apply steady p res­
sure to the br ake ped al. Do no t pu mp the ped­
a l. A puls ing in t he bra ke peda l ind icates that
the system is he lping yo u to b rake the vehicle .
Brake assist system
The brake assist system can decrease b ra kin g
d ista nce. It increases braking powe r w hen the
d river p resses the brake pedal quickl y in eme r­
gency situa tions . You mus t press and ho ld the
b rake peda l until the situation is over. In vehi­
cles with adaptive cruise control*, the brake
assist system is more sensitive i f the d istance
detected to the vehicle ahead is t oo smal l.
Anti-slip regulation (ASR)
ASR reduces engine power w hen the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Electronic differential lock (EDL )
The E DL brakes wheels that are spinn ing and
transfers the drive powe r to the o ther d rive
wheel o r whee ls if the vehic le is equipped with
a ll whee l drive*. This funct ion is available up
to about 7S mph (120 km/h).
I n extreme cases , EDL automatica lly swit ches
off to help keep the brake on the braked whee l
from overheating. ED L wi ll switch on again au­
tomatically when conditions have returned to normal.
Dynamic steering*
On vehicles wi th dynam ic s teeri ng, ES C helps
stab ilize the steer ing in cer tain sit uations.
Electronic interaxle differential lock
function*
T he ele ctronic i nte raxle di fferentia l lock f unc ­
tion ac tiva tes when dr iving t hrough curves.
B ra king is targeted towar d the whee ls on the
inside of the curve as needed . This helps to
min imi ze front whee l skid, improves traction
and allows for more precise driving throug h
cu rves .
A WARNING
- ESC, ABS, ASR , EDL, dynamic steering*
and the elect ronic interaxle differential
loc k function* cannot ove rcome t he laws
of physics . This is espe cially im po rtant
on slippery o r we t road s.
If the sys tems
begin actin g to stabilize your veh icle, you
should immediately change yo ur speed
to match the road and t raffic conditions .
Do not let the increased safety provided
by these systems tempt you to take risks. Doing so will increase the risk of a loss of
veh icle cont ro l, collision and ser io us per­
sonal injur ies .
-Always ada pt your speed to road , traffic
and wea ther conditions. The risk of los­
ing contr ol of the vehicle i ncreases wh en
d riving too fast, espe cially through
curve s and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys ­
tem, EDL, ASR, dynam ic steering * and
the elect ron ic interaxle differential lock
function * cannot prevent co llisions.
- Always accelerate with s pecial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance sys tems that cannot al­
ways he lp to red uce the risk of loss of ve ­
h icle co nt ro l.

216 Fuel supply and filling your fuel tank
-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driv ing.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time.
(CT) Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fuels that fai l to meet the
specified criteria in this chapter.
- If yo u are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel sup plier.
- Do not use fuel for which the contents cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build- up caused by
the type of gasoline you use.
A lthough gasoline grades differ from one
manufacturer to another, they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to co llect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and fuel
systems clean, they a re not equally effec­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
f uels, carbon deposit build-ups can rob yo ur
engine of peak performance.

Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually- for detailed
instructions see

You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 278.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your veh icle. For
more information about fuel specifications,
see
¢ page 215.
Your vehicle fuel tank has an on board refuel­ li ng vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly wh ile protecting the environment,
please fo llow this refueling procedure careful­
ly.
.8, WARNING
Under normal operating cond itions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must

Only if the level of the oil is at or below the min imum mark -and no oil that expressly
conforms to Audi oil standard VW 502 00
specifications is available -may you top off
with a high quality engine oil, preferably syn­
thetic -based, that meets ACEA A3 or API SM
specifications, but even then, only in viscosity
grades SAE SW-40, SAE SW-30, or SAE
OW-40. However, during the entire time be­
tween oil change intervals, never top off with
more than a total of 0.5 qt/liter engine oil
that does not conform to Audi oil specification
vw 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your authorized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834
or visit our web site at www.audiusa.com or
www.audicanada.ca. Here you will also find a current list of oils (manufacturers, brand
names etc .) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your vehicle's War­ ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter­
vals is so very important because the lubricat­ ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author­ ized Audi Service Advisor.
Under some circumstances the engine oil
should even be changed more frequently.
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods.
Detergent additives in the oil will make fresh
oil look dark after the engine has been run-
Checking and filling 223
ning for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine oil
that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet . Your dealer will have to
deny warranty coverage unless you present to
the dealer proof in the form of Service or Re­
pair Orders that all scheduled maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports .
In order to provide effective lubrication and
cooling of internal engine components, all in­
ternal combustion engines consume a certain
amount of oil. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see
¢ page 194) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida-
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump-
tion may increase over time until replacement
of worn components may become necessary. ..,.

and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
co page 221.
The fl uid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .

brake system should be thoroughly checked
by an authorized Audi dealer or other quali­
fied fac ility and the cause corrected. If the
brake fluid level is too low, the brake war ning/
in dicato r light w ill illuminate . Contact an au­
thor ized A udi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moistu re from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
dec rease braking per formance.
Therefore, the brake flu id must be changed
e ver y two yea rs. A lways use new b rake fluid
which confo rms to Fede ral Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id rese rvoi r ca n be difficult to

have the brake fl uid changed by yo ur a utho r­
ized
Audi dealer. Your dea ler has the correct
too ls, the right brake fluid and the know-how
to do this for you .
A WARNING
-Brake flu id is poisonous. It must be stor­
ed only in the closed or iginal conta iner
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
prop riate brake flu id . Obse rve these pre ­
cautions:
- Use only brake fluid that meets SA E
specification
J 1703 and conforms to
Federa l Moto r Ve hicle Standard 1 16 .
A lways check with your authorized A udi
dealer to make sure you are using the
correct brake fluid . The cor rect type of
brake flu id is also ind icated on the

- The brake fluid must be new . Heavy use
of the brakes can cause a vapo r lock if
the b ra ke fluid is left i n the system too
l o ng. This can se riously affect the effi ­
c iency of the br akes as well as your

232 Checking and filling
-Always wear eye protection. Do not let
battery acid or any lead particles get on
your skin or clothing . Shield your eyes .
Explosive gases can cause blindness or
other injury .
- Battery acid contains sulfuric acid . Sulfu­
ric acid can cause blindness and severe
burns .
- Always wear gloves and eye protection.
Do not tilt the battery because acid
could leak out of the ventilation open­
ings.
- If you get battery acid in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get
medical attention .
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
= When working on the battery , be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces hydrogen gas which is explosive and
could cause personal injury .
- Always keep the battery well out of the
reach of children .
- Before work is done on the electrical sys­ tem, disconnect the negative ground ca­ble.
- Before performing any work on the elec­
trical system, switch
off the engine and
ignition as well as any electrical equip ­
ment . The negative cable on the battery
must be disconnected . If you are just go­
ing to replace a light bulb, then it is
enough to switch
off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you will set off the alarm. -
When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable . Never inter ­
change the cables - this could start a fire!
- Never charge a frozen or a thawed-out
battery .
It could explode! If a battery has
frozen, then it must be replaced . A dis­
charged battery can freeze over at 32 °F
(0 °C) .
-Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery .
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery.
A WARNING
California Proposition 6S Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems. Wash hands after han­
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en­ gine is running, otherwise, you will dam­
age electronic components in the electri­
cal system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced .
