Automatic
transmission
tiptronic
Introduction
The automatic transmission is controlled elec
tronically. The transmission upshifts or down
shifts automatically depending on which drive
program is selected. The power is transferred
by a torque converter .
When a
mode rate d riv in g s ty le is used, the
transmission selects the most econom ica l
driving mode. It w ill then change up early and
delay the downshifts to g ive better fuel econ
omy.
T he transmission switches to a sporty mode
after a k ick-down or when the driver uses a
spo rty driving sty le characterized by quick ac
celerator pedal movements, heavy accelera
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can a lso select the gears
manually ( tiptronic mode ) c:> page 12 7.

@ Tips
-When you shift into the next lower gear,
the transmission will downshift only
when there is no possibility of over-rev
ving the engine.
- When the kick-down comes on, the
transmission will shift down to a lower
gear, depending on vehicle and engine
speeds.
- Tiptron ic is inoperative when the trans
mission is in the fail-safe mode.
- Hybrid drive*: electric driving is not pos
sible in tiptronic mode.
Kick-down
Kick-down enables maximum acceleration .
When you depress the accelerator pedal be
yond the resistance point, the automatic
transmission downsh ifts into a lower gear, de
pending on vehicle speed and engine speed .
The upshift into the next higher gear takes
place once the max imum specified engine
speed is reached .
_& WARNING
Please note that the drive wheels can spin
if kick-down is used on a smooth slippery
road -there is a risk of skidding .

Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
all ch ildren, especially those 12 years and
younger, a lways ride in the back seat properly
restrained for their age and size. The airbag
on the passenger side makes the front seat a
potentially dangerous place for a child to ride.
The front seat is not the safest place for a
child in a forward-facing child safety seat.
It
can be a very dangerous place for an infant or
a child in a rearward-facing seat.
The Advanced Airbag System in your veh icle
has been certified to comply w ith the Requ ire
ments of United States Federa l Motor Vehicle
Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front ai rbag on the
passenger side to be turned off ("sup
p ressed") if a ch ild up to about one year of
age restrained in one of the rear-facing or for
ward -facing infant restraints listed in Federal
Motor Vehicle Safety Standard 208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed on the front passenger seat . For a listing of the child re
straints that were used to certify compliance
with the US Safety Standard
Q page 180.
The PASSENGER AIR BAG OFF light in the in
strument panel tells you when the front Ad
vanced A irbag on the passenger side has bee n
turned off by the electronic control unit.
Each t ime you turn on the ignition, the
PAS
SENGER AIR BAG OFF
light will come on for a
few seconds and :
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small child or child restraint on the front passenger seat,
- will go off if the front passenger seat is oc
cupied by an adult as registered by the
weight-sensing mat
Q page 168, Monitor
ing the Advanced Airbag System .
The PASSENGER AIR BAG OFF light comes on
when the control un it detects a total weight
on the front passenger seat that requires the
front airbag to be turned off.
Airbag system 159
If the total weight on the front passenger
seat is more than that of a typical 1 year-o ld
c hild but less than the weight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
light does not come on). If the PASSENGER
AIR BAG OFF
light does not come on, the
front a irbag on the passenger side has not
been turned off by the electronic con trol unit
and can deploy if the contr ol unit senses an
impact that meets the cond itions stored in its
memory .
For example, the airbag may deploy if:
-a small ch ild that is heav ie r than a typical 1
year-old ch ild is o n the front passenger seat
(regard less of whether the child is in one of
the child safety seats listed
Q page 180), or
- a child who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on.
The front airbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
light does not illum inate and stay lit) even if a
small adult or teenager, or a passenger who is
not sitting uprig ht with their back against a
non-reclined backrest w ith their feet on the
vehicle floor in front of the seat is on the front
passenger seat~
page 140, Proper seating
position for the driver.
If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criteria to reduce
the risk of injury thro ugh interaction with the
airbag . "Low risk" deployment occ urs in those
crashes that take place at lower dece lerat ions
as defined in the electronic control unit
Q page 168, PASSENGER AIR BAG OFF light .
Always remember, a child safety seat or infant
carr ier installed on the front seat may be
struck and knocked out of posit ion by the rap
idly inflating passenger's airbag in a frontal
collision . The airbag could greatly reduce the
effectiveness of the child restraint and even
seriously injure the child during inflation. •

164 Airbag sys te m
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lling
the forward-facing child restraint. The backrest must be adjusted to an upr ight
posit ion.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is switched
on.
Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack
ets, and more. The function of the system in
the front passenger seat is checked by the
e lectronic control un it when the ignit ion is on.
The control unit mon itors the Advanced Air
bag System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you m ust take care to
prevent it from be ing damaged. Damage to
the seat may prevent the Advanced Airbag for
the front passenger seat from doing its job in
a crash .
The front Advanced Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .
T he cont ro l unit "dec ides " w het her to fire
the front airbags based on the information
received from the crash senso rs . The contro l
unit a lso "decides" whethe r the safety be lt
pretensioners should be activated . -
An Advanced A irbag w ith gas generator and
cont ro l valve for the d river inside the steer
ing wheel h ub.
- An Advanced A irbag with gas ge nerator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight-sensing mat under the up ho lstery
pad ding of the front passenger seat cushion
that measures the total weight on the seat.
The informat ion registered is sent continu
ously to the electronic contro l unit to regu
late deployment of the front Advanced Air bag on the passenger side .
- An airbag monitor ing system and i ndicator
light in the i nstr ument cluster ~
page 168 .
-A sensor in each front seat registers the dis
tance between the respective seat a nd the
steer ing whee l o r i ns trument panel. The i n
formation registered is sent cont inuously to
t he ele ctr onic cont ro l uni t to regula te de
p loyment o f the front Advance d Airbags .
- The
PASSENGER AIR BAG OFF ligh t comes
on and st ays on in the cen ter o f the instr u
ment panel
~ page 168, fig . 169 and tells
you whe n the front Advanced Airbag on the
passenger side has been tu rned off .
- A sensor below the safety be lt latch for the
front seat passenger to measure the tension on the safety be lt . The tension on the safety

airbag status.
Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning properly cannot provide supplemental pro
tection in a frontal crash.
- If the airbag indicator light¢
page 15
comes when the vehicle is being used,
have the system inspected immediately
by your authori zed Audi dealer. It is pos
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should .
A WARNING
If the front airbag inflates, a child without
a child restraint, in a rearward-facing child
safety seat or in a forward-facing child re
straint that has not been properly installed
will be seriously injured and can be killed.
- Even though your vehicle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, always ride on the back seat properly restrained for their
age and size.
- Always install forward or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional circumstan
ces and the
PASSENGER AIR BAG OFF
light does not appear and stay on, imme
diately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your au
thorized Audi dealer.
- A tight tether or other strap on a rear
ward-facing child restraint attached to
the front passenger seat can put too
much pressure on the weight-sensing
-
mat in the seat and register more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adult were on the seat and deploy the Advanced Airbag when it
must be suppressed causing serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re
straint on the front passenger seat, al
ways move the seat into its rearmost po
sition in the seat's fore and aft adjust
ment range, as far away from the airbag
as possible. The backrest must be adjust
ed to an upright position. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when
ever the ignition is switched on .
A WARNING
-
-
-If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, make sure the
adult is properly seated and restrained at
one of the rear seating positions.
- Have the airbag system inspected by
your authorized Audi dealer before trans
porting anyone on the front passenger
seat.
(D Tips
If the weight-sensing mat in the front pas
senger seat detects an empty seat, the
front airbag on the passenger side will be
turned off, and
PASSENGER AIR BAG OFF
will stay on.
Repair , care and disposal of the airbags
Par ts of the airbag system are ins talled at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision. .,..

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 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
driver 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.
A 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 characteristics as the components origi
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A 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.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 170 S ide a irbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests¢
fig. 170 and the rear
backrest* facing the doors. They are identified
by the word "AIRBAG".
The side airbag system basically consists of:
-the electronic control module and external
side impact sensors
- the two airbags located in the sides of the
front backrests and the two airbags* located
in the rear backrest
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly ..,.

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 Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein
forces driver safety. It reduces the risk of slip
ping and improves driving stability. ESC de
tects critical s ituations such as the vehicle
Intelligent technology 197
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy
namic steering*, hill descent assist and selec
tive wheel torque control.
Anti-lock braking system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres
sure to the brake pedal. Do not pump the ped
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au
tomatically when conditions have returned to
normal.

Brake system
Operating conditions and driving habits
The brakes on today's automobi les are sti ll
subject to wear, depending largely on operat
ing conditions and dr iv ing habits ¢&. . On
vehicles that are e ither driven mostly in stop
and -go city traffic or are driven hard, the
brake pads should be checked by your author
ized Audi dealer more often than specified in
the
Warranty & Maintenance booklet . Failure to have you
r brake pads inspected can result
in reduced brake performance.
On steep slopes , you should use the braking
effect of the engine . This way, you prevent un
necessary wear on the b rake system . If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter
vals.
Noises may occur when braking depending on
the speed, braking force and outside condi
t ions such as temperature and humidity .
Moisture or road salt
Under certain conditions, for example, when
driv ing through water or very heavy rain, or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
freezing conditions ice) on the brake pads. A
few careful brake applications should dry off
the brake pads or remove any ice coatings.
When you are driving at higher speeds with
the windshie ld wipers on, the brake pads will
briefly touch the brake discs in regu lar inter
vals so as to improve reaction time when brak
ing on wet surfaces . You, the driver, will not
notice anything .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and the brakes are not used . Here too,
you should clean off accumulated salt coating from brake discs and pads w ith a few careful
applications of the brake ¢.& .
Corrosion
There may be a tendency for dirt to build up
on the brake pads and corros ion to form on
the discs if the car is not driven regularly or
o n Ly for short trips with little use of the
brakes.
If the brakes are not used frequently, or if cor
r os ion has formed on the d iscs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed¢ ,&. .,..
