Automatic gearbox 90Automatic gearboxApplies to vehicles: with R tronicDescriptionR tronic is an automatic sequential-shift gearbox using shift-by-wire
technology to operate the clutch and change the gears.
The gears are engaged manually (the principle is similar to a manual
gearbox) but they can also be shifted automatically. The engine can
be started and stopped in any gear ⇒page 82.
The driver information system displays the selected mode, the
engaged gear and the sport function ⇒fig. 78.M - Manual mode
In this mode, you use the selector lever ⇒page 91 or the paddle
levers on the multi-function steering wheel ⇒page 93 to change
the forward gears up and down.
A - Automatic mode
In this mode the forward gears are shifted up and down automati-
cally according to the engine load and road speed ⇒page 92.
R - Reverse gear
Reverse gear must only be engaged when the vehicle is stationary
and the engine is idling ⇒.
To engage reverse gear press the brake pedal then move the
selector lever to the right before pulling it briefly towards the R
symbol. The reversing lights come on when reverse gear is engaged
with the ignition on.
N - Neutral
To engage neutral gear, the selector lever has to be moved to the
right or left. If reverse gear is engaged, move the selector lever to
the left. If a forward gear is engaged, move the selector lever to the
right.
Sport function
Press the button to activate the sport function. Upshifts are
then delayed to make use of the maximum engine power. The shift
time is reduced and the accelerator pedal has a lighter response. In
addition, the car does not automatically shift up a gear before the
maximum engine speed is reached when you are in manual mode.
The car will automatically shift up a gear in the normal way when
you are in automatic mode.

Safe driving 102Safe drivingGeneral notesSafety is the first priority
Your safety is our first priority.This chapter contains important information, tips, sugges-
tions and warnings that you should read and observe for
your own safety and the safety of your passengers.
WARNING
•
The information in this chapter is important for the driver of
the vehicle and all passengers. The other chapters in this manual
(and, where applicable, in the other literature supplied with the
vehicle) contain further important notes which you should read
and observe for your own safety and that of your passengers.
•
Ensure that the complete vehicle wallet is always in the vehicle.
This is especially important when you lend or sell the vehicle to
others.
Safety features
The safety features listed here are part of the vehicle's
occupant restraint system. They work together to help
reduce the risk of injury in a wide variety of accident situ-
ations.Your safety and the safety of your passengers should not be left to
chance. In the event of an accident, the safety features incorporated
in your vehicle are capable of reducing the risk of injury. These are
just a few of the safety features in your Audi:•
Three-point seat belts for all seats,
•
Belt force limiters for the front seats,
•
Belt pre-tensioners for the front seats,
•
Front airbags,
•
Head/thorax airbags in the backrests,
•
“ISOFIX” mountings* for “ISOFIX” child safety seats on the front
passenger's seat,
•
Height-adjustable head restraints in the backrests,
•
Adjustable steering column.
These individual safety features are harmonised to provide you and
your passengers with the best possible protection in accident situ-
ations. However, they can only be effective if you and your passen-
gers sit in the correct position and adjust and use the safety equip-
ment properly.
For these reasons, this chapter explains why these safety features
are so important, how they can protect you, what you need to
remember when using them, and how you and your passengers can
gain the most benefit from them. There are also a number of impor-
tant safety warnings which you and your passengers should always
observe in order to minimise the risk of injury.
Safety is everyone's responsibility!
Before every trip
The driver is responsible for the safety of the passengers
and the safe operation of the vehicle at all times.For your own safety and the safety of your passengers,
always note the following points before every trip:
– Make sure that all lights and turn signals are working
properly.

Safe driving 104Correct sitting positionsCorrect sitting position for driver
The correct driving position is important for safe and
fatigue-free driving.For your own safety, and to reduce the risk of injury in the
event of an accident, we recommend the following driving
position.
– Adjust the steering wheel so there is a distance of at least
25 cm between the steering wheel and your breastbone
⇒fig. 82.– Move the driver's seat forwards or backwards so that you
can press the accelerator, brake and clutch pedals all the
way to the floor with your knees slightly bent ⇒.
– Make sure that you can comfortably reach the top of the
steering wheel.
– Adjust the head restraint so that the top of the head
restraint is level with the top of your head ⇒fig. 83.
– Adjust the backrest to an upright position so that your
back remains in contact with the upholstery.
– Fasten your seat belt correctly ⇒page 109.
– Keep both feet in the footwell so that you are in full
control of the vehicle at all times.
For detailed information on how to adjust the driver's seat, see
⇒page 67, “Seats and storage”.
WARNING
An incorrect driver sitting position can result in serious personal
injury.•
Adjust the driver's seat so there is a distance of at least 25 cm
between your breastbone and the centre of the steering wheel
⇒fig. 82. The airbag system will not be able to protect you prop-
erly if you sit closer than 25 cm.
•
If physical limitations prevent you from maintaining the
minimum distance of 25 cm, please consult a qualified workshop.
The workshop will be able to tell you whether your vehicle can be
suitably modified.
•
While driving, always hold the steering wheel with both hands
on the outside of the rim at about the 9 o'clock and 3 o'clock posi-
tion. This reduces the risk of injury if the driver's airbag inflates.

•
Never hold the steering wheel at the 12 o'clock position, or
with your hands inside the rim or on the steering wheel hub. This
could result in serious injuries to the arms, hands and head if the
driver's airbag inflates.
•
To reduce any risk of injury to the driver during a sudden brake
application or in an accident, never drive with the backrest tilted
too far back. The airbag system and seat belts can only provide
proper protection when the backrest is in an upright position and
the driver is wearing the seat belt in the correct position. The
further the backrest is tilted back, the greater the risk of injury due
to incorrect positioning of the belt webbing or an incorrect sitting
position.
•
Adjust the head restraint properly so that it can give maximum
protection.
Correct sitting position for front passenger
The front seat passenger must sit at least 25 cm away
from the dash panel so that the airbag has enough room
to inflate and give maximum protection in an accident.For your own safety and to reduce the risk of injury in the
event of an accident, we recommend adjusting the front
passenger's seat as follows:
– Move the front passenger's seat as far back as possible
⇒.
– Adjust the backrest to an upright position so that your
back remains in contact with the upholstery.
– Adjust the head restraint so that the top of the head
restraint is level with the top of your head ⇒page 106.
– Keep both feet in the footwell in front of the seat.– Fasten your seat belt correctly ⇒page 112.
In exceptional cases you can disable the front passenger's airbag
⇒page 120.
For detailed information on how to adjust the front passenger's
seat, see ⇒page 67, “Seats and storage”.
WARNING
A passenger sitting out of position in the front seat can suffer
serious injuries.•
Adjust the front passenger's seat so there is a distance of at
least 25 cm between your breastbone and the dash panel. The
airbag system will not be able to protect you properly if you sit
closer than 25 cm.
•
If physical limitations prevent you from maintaining the
minimum distance of 25 cm, please consult a qualified workshop.
The workshop will be able to tell you whether your vehicle can be
suitably modified.
•
Always keep your feet on the floor when the vehicle is moving;
never rest them on the instrument panel, out of the window or on
the seat. If you sit in an incorrect position, you increase your risk
of injury in the event of sudden braking or an accident. If the airbag
is triggered, you could sustain potentially fatal injuries by sitting
out of position.
•
To reduce the risk of injury to the front passenger in the case of
sudden braking or an accident, the passenger should never travel
in a moving vehicle with the backrest reclined. The airbag system
and seat belt can only provide proper protection when the back-
rest is in an upright position and the passenger is wearing the seat
belt in the correct position. The further the backrest is tilted back,
the greater the risk of injury due to incorrect positioning of the belt
webbing or an incorrect sitting position.
•
Always adjust the head restraints properly for maximum
protection.

Technical data The physical principles involved in a frontal collision are relatively
simple:
Both the moving vehicle and the passengers possess energy, which
is known as “kinetic energy” ⇒page 110, fig. 87. The amount of
“kinetic energy” depends on the speed of the vehicle and the weight
of the vehicle and passengers. The higher the speed and the greater
the weight, the more energy there is to be absorbed in an accident.
The most significant factor, however, is the speed of the vehicle. If
the speed doubles from 25 km/h to 50 km/h, for example, the kinetic
energy increases by a factor of four. Because these passengers are
not restrained by seat belts, the entire amount of kinetic energy has
to be absorbed at the point of impact ⇒fig. 88. This would result in
serious or potentially fatal injury.
Even at urban speeds of 30 km/h to 50 km/h, the forces acting on the
occupants in a collision can reach the equivalent of 1 ton (1000 kg)
or more. At greater speed these forces are even higher. A rule of
thumb: if the speed doubles, the forces increase by a factor of four.
Passengers who do not wear seat belts are not “attached” to the
vehicle. In a frontal collision they will continue to move forward at
the speed their car was travelling just before the impact.
What happens to passengers not wearing seat belts?
Passengers not wearing seat belts risk fatal injuries in the
event of an accident.In a frontal collision, unbelted passengers will be thrown forwards
and make violent contact with the steering wheel, dashboard, wind-
screen, etc ⇒fig. 89. Passengers not wearing their belts risk being
thrown out of the car, resulting in potentially fatal injuries.
The common belief that occupants can brace their weight with their
hands in a minor collision is false. Even at low speeds the forces
acting on the body in a collision are so great that it is not possible
to hold yourself in the seat.

Airbag system 116•
If you sell the vehicle, please remember to pass on the
complete Service Wallet to the new owner. If the front passenger's
airbag has been deactivated, it is important that the new owner is
also given the relevant documents.
•
The relevant safety requirements must be observed when the
vehicle or components of the airbag or belt tensioner systems are
scrapped.
•
In an accident in which one or more airbags are triggered the
alternator and the starter are - for safety reasons - both discon-
nected from the battery via a pyrotechnic circuit breaker.
−Any repairs to the pyrotechnic circuit breaker must always
be performed by a qualified workshop (accident risk).
−The relevant safety requirements must be observed when
the vehicle or the circuit breaker are scrapped.
When are the airbags triggered?
The airbag system is triggered in collisions with a severe
impact.The airbag system is designed so that the airbags for the driver and
front passenger are triggered in a severe frontal collision.
In severe side collisions the side airbags are triggered on the impact
side of the vehicle.
In certain types of accident the front airbags and the side airbags
may be triggered together.
The airbag system is not triggered in minor frontal or side collisions,
or in rear collisions or if the car overturns. In these situations the
occupants are protected by wearing the seat belts.
Factors determining the triggering response
It is not possible to define the exact triggering response of the
airbag system in all possible situations, since the circumstances in different types of accident will vary considerably. Important factors
include, for example, the nature (hard or soft) of the object which
the car hits, the angle of impact, vehicle speed and so on.
Whether the airbags are triggered depends primarily on the vehicle
deceleration rate resulting from the collision. By processing the
signals from the sensors located in the vehicle, the electronic
control unit is immediately able to evaluate the severity of the colli-
sion and activate the restraint systems accordingly. If the decelera-
tion rate is below the predefined reference value in the control unit
the airbags will not be triggered, even though the accident may
cause extensive damage to the car.
Note
The airbag releases a fine dust when it inflates. This is quite normal
and does not mean there is a fire in the vehicle.Front airbagsDescription of front airbags

Technical data The front airbag for the driver is located in the padded hub of the
steering wheel ⇒page 116, fig. 95. The front airbag for the front
passenger is in the dashboard above the glove box ⇒fig. 96. The
locations of the airbags are marked with the word “AIRBAG”.
In conjunction with the three-point seat belts, the front airbags give
additional head and chest protection for the driver and front
passenger in the event of a severe frontal collision ⇒ in “Impor-
tant safety notes on the front airbag system” on page 117.
How the front airbags work
When fully inflated, the airbags reduce the risk of head or
chest injury.
The airbag system is designed so that the airbags for the driver and
front passenger are triggered in a severe frontal collision.
In certain types of accident the front airbags and the side airbags
may be triggered together.
When the system is triggered, the airbags fill with a propellant gas
and open out in front of the driver and front passenger ⇒fig. 97. In
order to provide the desired extra protection in an accident, the
airbags have to inflate extremely rapidly (within fractions of a
second). The fully deployed airbags cushion the forwards move-
ment of the front occupants and help to reduce the risk of injury to
the head and the upper part of the body.
Special openings in the airbag allow the gas to escape at a
controlled rate to restrain the forward movement of the occupant's
head and torso. Once the impact has been absorbed, the airbag
deflates sufficiently for the front occupants to see forward.Important safety notes on the front airbag system
There are a number of safety points concerning the airbag
system which you should remember. This will help to
reduce the risk of injury in an accident.

Airbag system 118
WARNING
•
It is important for the driver and front passenger to maintain a
distance of at least 25 cm from the steering wheel or dashboard
⇒page 117, fig. 98. The airbag system will not be able to give the
required protection if you sit too close to the steering wheel or
dashboard. There is also a risk of injury if the airbags are inflated.
The front seats and head restraints must always be positioned
correctly for the height of the occupant.
•
If you do not wear a seat belt, if you lean forward or to the side,
or are not seated correctly while the vehicle is in motion, you are
at greater risk of injury. Should the airbag system be triggered in
an accident there is an even greater risk of injury.
•
Never let a child travel on the front seat without an appropriate
restraint system. If the airbag is triggered in an accident, the child
could sustain serious or fatal injuries ⇒page 122, “Child safety”.
•
Never install a rearward-facing child safety seat on the front
passenger's seat unless the front passenger's airbag has been
deactivated. However, if you have no alternative but to use a rear-
ward-facing child seat on the front passenger's seat, the front
passenger's airbag must be deactivated beforehand by means of
the key-operated switch ⇒page 120, “Deactivating the airbags”.
Failure to observe this precaution could result in serious or poten-
tially fatal injury.
•
Occupants sitting in the front of the car must never carry any
objects or pets in the space between them and the airbags, or
allow children or other passengers to travel in this position.
•
Do not cover or stick anything on the steering wheel hub or the
soft plastic surface of the airbag unit on the passenger's side of
the dashboard, and do not obstruct or modify them in any way.
These parts should only be cleaned with a dry cloth (or with a
cloth moistened with plain water). It is also important not to
attach any objects such as cup holders or telephone mountings to
the surfaces covering the airbag units.
•
Any work on the airbag system or removal and installation of
the airbag components for other repairs (such as repairs to the
steering wheel) should be performed by a qualified workshop.Note
If necessary, you can deactivate the front passenger's airbag by
means of the key-operated switch ⇒page 120, “Deactivating the
airbags”.Side airbagsDescription of side airbags
The airbag system is not a substitute for the seat belts.The side airbags are located in the backrest padding of the front
seats ⇒fig. 99. The locations of the airbags are marked with the
word “AIRBAG”.
In conjunction with the three-point seat belts, the side airbags give
the occupants additional protection for the whole upper part of the
body (i.e. the chest, stomach and pelvis) in the event of a severe side

Intelligent technology 132Intelligent technologyElectronic stabilisation program (ESP)The Electronic Stabilisation Program increases the car's
stability.Description
The anti-lock brake system (ABS), the electronic differential lock
(EDL) and the traction control system (ASR) are all integrated into
the electronic stabilisation program (ESP). The ESP is designed to
enhance the control over the vehicle in critical handling situations,
such as when accelerating and cornering. It reduces the tendency to
skid at all speeds under all road conditions and improves the
stability and roadholding of the vehicle. ESP helps the car to start
moving, accelerate and climb a gradient in slippery conditions
where this may otherwise be difficult or even impossible. The ESP is
switched on automatically when the engine is started. It should
normally be left switched on at all times for optimum car stability.
Driving situations
If the car is oversteering (rear wheels losing grip first) the ESP
mainly brakes the outside front wheel; if the car is understeering
(front wheels losing grip first), the ESP brakes the inside rear wheel
and possibly also other wheels. This automatic brake application is
accompanied by characteristic noises.If, when braking, one of the wheels is turning too slowly in relation
to the road speed and is close to locking up, the system will reduce
the pressure in the brake line to this wheel. The driver is made aware
of this control process by a pulsating of the brake pedal and accom-
panying noise. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application
- do not “pump” the brake pedal. However, the ABS will not neces-
sarily guarantee shorter stopping distances in all conditions. For
instance, on loose gravel or fresh snow on top of an icy surface the
stopping distance with ABS may even be slightly longer.
Whenever it detects a significant difference in the speed of the driven
wheels of one axle (for example, if the road is slippery on one side)
the electronic differential lock (EDL) applies the brake to slow down
the spinning wheel so that more of the power is directed to the
other wheels. This function is active up to about 100 km/h. The brake
system will make noises while it is working.
If one wheel has less grip and starts spinning (for instance, if one of
the driven wheels is on ice), press the accelerator hard until the car
starts moving.
If the wheels start to spin, the traction control system (ASR) auto-
matically reduces the engine torque to match the amount of grip
available.
Activating the sport mode
If required (for instance if you want to use the launch control), you
can switch the traction control system (ASR) and electronic stabili-
sation program (ESP) to sport mode by pressing the button
once. The ESP warning lamp will light up and the message ASR off
will appear in the driver information system display. The amount of
wheel slip is regulated according to the road speed. You should only
use this feature if your driving ability and traffic conditions allow
you to do so safely.
