Facility immediately to have the malfunction cor­
rected. The color of the indicator light depends
on the vehicle speed.
A WARNING
-
Driving at higher speeds without the rear
spoiler deployed can impair handling charac­ teristics, making the vehicle harder to con ­
trol.
- Always make sure that the spoiler is de­
ployed when driving at speeds over 85 mph
(140 km/h). If the rear spoiler warning/indi­
cator light in the instrument cluster comes
on, the rear spoiler may not have deployed.
- Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed .
Have the spoiler inspected as soon as possi­
ble by an authorized Audi dealer or qualified
workshop.
- Always obey speed limits and other traffic
laws.
A WARNING t =
Improper operation of the rear spoiler can
cause crushing injuries.
-
- Always make sure that nobody, especially
children, is in the way when the rear spoiler
is deployed or retracted.
(D Note
- Never push on the vehicle on the rear spoil­
er. This could cause damage.
- To prevent damage to the rear spoiler do
not lean or place anything on it.
- Only operate the rear spoiler manually when
the luggage compartment lid is close and
the rear spoiler moving parts are not
blocked. Otherwise, damage could occur.
@ Tips
Clean the rear spoiler compartment every 2 to
3 months. To function correctly, the rear
spoiler must be free of ice , snow and leaves.
Intelligent Technology
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engtne.
When a vehicle with a conventional energy sys­
tem is not driven for a long time, the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certain circumstances , there
could may not be enough energy to start the en­
gine.
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat ­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off , it manages the energy distribution
to the different electrical components. Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from draining and to maintain the starting ability.
Dynamic energy management
While driving , dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment.
It controls the battery
charge level so that the amount of energy is not ..,_

Improperly worn safety belts
Incorrectly positioned safety belts can cause se­
vere injuries.
Wearing safety belts improperly can cause seri­
ous injury or death. Safety belts can only work
when they are correctly posit ioned on the body .
Improper seating positions reduce the effective­ ness of safety bel ts and w ill even increase the
risk of inju ry and death by moving the safety be lt
to criti cal areas of the body . Imprope r seating
positions also increase the risk of serious injury
and death when an airbag dep loys and strikes an
occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all
vehicle occupants and especially for children.
Therefore:
• Never pe rm it anyone to assume an incor rect
seated position in the vehicle while traveling

A WARNING
Improperly worn safety belts increase the risk
of ser ious perso nal injury and death whenever
a veh icle is being used .
- Always make sure that all veh icle occupants
are correctly restrained and stay in a correct
seated posit ion wheneve r the ve hicle is be­
ing used.

Safety belt tensioner
How safety belt pretensioners work
In front, side and rear -end collisions above a
particular severity and in a rollover, safety belts ore tensioned automatically.
Pyrotechnic safety belt pretensioners
The safety belts are eq uipped w ith safety belt
prete nsione rs. The system is ac tiva ted by sensors
i n front, side and rear-end collisions of great se ­
verity and in a rollover . This tightens the belt and

one who is heavier than the person actua lly
sitting on the seat . The p resence of addi­
t ional objects could cause the passenger
front airbag to be turned on when it shou ld
be off, or could cause the airbag to work in a
way that is different from the way it would
have worked witho ut the object on the seat.

Advanced Airbag System components
The front passenger seat in yo ur vehicle has a lot
of
very important parts of the Advanced Airbag
Sys tem in it . These pa rts in cl ude the capacitive
passenger detection system, w iring, brackets,
and mo re. The control un it monitors the system
on the front passenger seat when the ign ition is
switched on and turns the airbag indicator light
on when a malfunct ion in the one of the system
components is detected
c::> page 208 . Because
the fro nt passenger seat contains important
pa rts of the Advanced Airbag System, you must
take ca re to preven t it from being damaged.
D amage to the seat may p revent the Advanced
Ai rbag System for the front passenger seat from
doi ng its job i n a crash.
The front Advanced Airbag System consists
of the follow ing :
- C rash sensors in the front of the vehicle that
measure vehicle accelerat ion/dece leration to
Airb ag sys tem
provide information to the Advanced A irbag
System about the severity of the cras h.
- An elect ronic contro l unit, with integrated
cras h sensors for front and side impacts . The
control un it "decides" whether to fire the front
airbags based on the information rece ived from
the crash sensors . The control unit also "de­
cides" whether the safety belt pretensioners
should be activated.
- An Advanced A irbag w ith gas generator for the
driver inside the steeri ng wheel hub .
- An Advanced A irbag w ith gas generator inside
the instrument panel for the front passenger.
-A capacit ive passenger detection system under­
neath the front passenger seat
cover. This sys­
tem measures the e lectr ica l capacitance of the
person in the seat. The information registered
is sent continuously to the elect ronic contro l
un it to reg ulate dep loyment of the front Ad­
vanced Airbag on the p assenger side.
- An airbag monitoring system and indicator
light
El in the inst rument cl uste r.
- A sensor in each front seat registe rs the d is­
t ance betwee n the respective seat and the
steer ing whee l o r ins trumen t pa nel. The infor­
mat ion registered is sent con tinuous ly to the
electronic contro l unit to regu late dep loyment
of the front Advanced Airbags .
- The
PASSENGER AIR BAG OFF~; lig ht comes

- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety be lt is latched or not and
transmits this information to t he electronic
cont rol un it .
A WARNING
Damage to the front passenge r seat can pre­
vent the front airbag from working prope rly.

More important things to know about front
airbags
Fig. 165 I nflated fro nt ai rbags
Safety be lts are impo rtan t to he lp keep front
seat oc cupants in the proper seated position so
that airbags can unfo ld properly and prov ide s up­
pleme nta l protection i n a fronta l co llision .
The front airbags are designed to provide addi­
t iona l protec tion fo r the chest and face of the
driver and the fron t seat passenger whe n:
- safety belts are worn properly,
- the seats have been positioned so that t he oc-
cupant is properly seated as far as possible
from the a irbag .
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have
placed on the seat could become dangerous pro ­
ject iles, and be pushed into you if the a irbag i n­
flates.
When an airbag deploys, fine dust is released.
This is norma l and is not caused by a fire in the
vehicle . This dust is made up mostly of a powder
used to lub rica te t he a irbags as they deploy.
It
cou ld irritate skin.
It is important to remembe r that wh ile the sup ­
pleme nta l airbag system is designed to reduce
the likelihood of serio us inj uries, othe r injuries,
for example swelling, bru is ing and minor abra­
s ions, can also happen when a irbags inflate . Air­
bags do not prote ct the arms or the lower p arts
of the body. Front airbags supp lement the three
point safety belts on ly in some frontal collisions
in which the vehicle dece leration is high enough
to deploy the airbags.

Airbag syste m
Front airbag s will not deploy:
- if the ignit ion is switched off when a crash oc -
curs,
- in s ide collisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by the
airbag system is less than the minimum thresh­
old needed for airbag deployment as registered
by the electronic contro l unit.
Th e front p asse nger airb ag w ill also not
depl oy:
- when the front passenger seat is not occupied,
- when the electrical capacitance measured by
the capacitive passenger detect ion system for
the front passenger seat indicates that the pas­
senger side frontal airbag must be switched off
by the electronic contro l unit (the
PASSENGER
AIR B AG OFF ~;
light~ page 208 and how
they work comes on and stays on) .
A WARNING
Sitting in the wrong position can increase the
risk of serious injury in crashes.
- To reduce the risk of injury when the airbags inflate, the driver and passengers must al­
ways sit in an upright position, must not
lean against or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbelted, out of position
or too close to the a irbag can be seriously
injured by an airbag as it unfolds with great
force in the blin k of an eye~
page 197.
A WARNING
A child in a rearward-facing chi ld seat insta l­
led on the front passenger seat will be ser i­
ously inju red and can be killed if the front air­
bag inf lates - even with an Advanced Airbag
System.
- T he inflating a irbag w il l hit the child seat or
infant carrier with great force and will
smash the chi ld seat and child against the
backrest, center armrest, door or roof.

- Never install a rearward facing chi ld safety
seat on the front passenger seat unless the
PAS SEN GER AIR BA G OFF ~; light comes
on and stays on . If the
PA SSE NGER AIR
BAG OFF~;
light does not come on and stay
on, the inflat ing airbag will hit the chi ld
safety seat or infant carrie r with great force
and will smash the child safety seat and
child against the bac krest, door or roof.
Have the airbag system inspected immedi­
ately by your authorized Audi dealer .
A WARNING
Objects between you and the airbag will in­
crease the risk of injury in a crash by interfer­
ing with the way the airbag unfolds or by be­
ing pushed into you as the airbag inflates.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never transport items on or in the area of
the front passenger seat. Objects could
move into the area of the front airbags dur­
ing braking or other sudden maneuver and
become dangerous projectiles that can
cause serious persona l injury if the airbags
inflate.
- Never place or attach accessories o r other
objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doo rs, ove r or near the area ma rked
"AIRBAG" on the steering wheel, instru ­
ment panel, seat backrests or between
those areas and yourself. These objects
could cause injury in a crash, especially
when the a irbags inf late.
- Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side a irbag or the front air­
bag during brak ing or in a sudden maneu­
ver . Objects near the airbags can become
projecti les and cause injury, part icularly
when the seat is reclined.
- Never p lace or t ransport objects on the
-
front passenger sea t. Objects on the front

Airbag system
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
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, suspension 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 example, increase the force levels meas­
ured 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 measured by
the sensors and prevent the airbag from deploy­ ing when it should.
A WARNING
-Changing the vehicle's suspension including use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.

Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
F ig. 169 Side airbag locat ion in t he drive r's seat
The side airbags are located in the sides of the
front seat backrests
c::> fig. 169 facing the doors .
They are identified by the word "AIRBAG".
The side airbags installed for the front seating
positions have been designed and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant sitting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used with properly installed child re­
straints. Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts
c::> page 189,
Airbag system c::>page 196, Child safety
c::> page 218 .
The side airbag system basically consists of:
- the electronic control modu le and external side
impact sensors
214
- the two side airbags located in the sides of the
front backrests
- the airbag warning light in the instrument clus-
ter.
The airbag system is mon itored electron ical ly to
make certain that it is functioni ng p roperly at all
times. Each time you turn on the ignition, the air­
bag system indicator light will come on for a few
seconds (self diagnostics) .
The side airbag system supplements the safety
belts and can help to reduce the risk of injury to
the driver's and front passenger's upper torso
and head on the side of the vehicle that is struck
in a side collision. The airbag deploys in side im­
pacts and only when the vehicle acceleration reg­
istered by the control unit is high enough. If this
rate is below the reference value programmed in­
to the control unit, the side airbags will not be
trigge red, even though the car may be badly
damaged as a result of the collision .
It is not pos­
sible to define an airbag triggering range that
will cover every possible angle of impact, since
the circumstances will vary conside rably between
one collision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
c::> page 216, Important safety in­
structions on the side airbag system .
Aside from their normal safety function, safety
belts work to help keep the driver or front pas­
senger in position in the event of a side collision
so that the side airbags can provide protect ion.
The airbag system is
not a substitute for your
safety belt. Rather, it is part of the overall occu­
pant restraint system in your vehicle . Always re­
member that the side airbag system can only
help to protect you if you are wear ing your safety
belt and wear ing it properly. This is another rea­
son why you sho uld always wear your safety
belts, not just because the law requires you to do
so
c::> page 189, General notes.
It is impo rtant to remember that while the sup­
plemental side airbag system is desig ned to re­
duce the likelihood of ser ious injuries, other inju­
ries, for example, swelling, bruising , friction
burns and minor abrasions can also be associated ..,.

with deployed side airbags. Remember too, side
airbags will deploy on ly once and on ly in certain
kinds of acc idents -your safety be lts are always
there to offer protection .
Vehicle damage, repair costs or even the lack of
vehicle damage are not necessarily an indication
of over-sensitive or failed airbag activation. In
some collisions, both front and side airbags may
inflate. Remember too, that airbags will deploy
only once and only in certain kinds of coll isions -
your safety belts are always there to offer protec­
tion in those acc idents in which airbags are not
supposed to deploy or when they have a lready
deployed.
The side airbag system will not deploy:
-when the ign ition is switched off
- in side collisions when the acceleration meas-
ured by the sensor is too low
- in front-end collisions
- in rear-end collisions
- in rollovers.
I n some types of accidents the front airbags and
side airbags may be triggered together.
_& WARNING
-Safety belts and the airbag system will only
provide protection when occupants are in
the proper seating position ¢
page 216.
-If the airbag indicator light q page 14
comes when the vehicle is being used, have
the system inspected immediate ly by your
authorized Audi dealer. It is possible that
the airbag will inflate when it is not sup­
posed to, or will not inflate when it shou ld.
Airbag system
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained.
Fig. 170 Inflated side a irbags on lef t side of vehicle
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area marked "AIRBAG". It ex­
pands between the side trim panel and the pas­
senger . In order to help provide this addit ional
protect ion, the side airbag must inflate w ith in a
fraction of a second at very high speed and with
great force . Th e supp lemental s ide airbag could
injure you if you r seating position is not proper or
u pr ight or if items are located in the area where
the supp lemental side airbag expands. This ap­
plies especially to children
c> page 218, Child
safety.
Supplemental side airbags inflate be­
tween the occupant and the door panel on the
side of the vehicle that is struck in certain side collision
c> fig . 170.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper part
of the body .
A fine dust may develop when t he airbag deploys .
This is normal and does not mean there is a fire
in the veh icle.

Airbag system
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always
properly wear safety belts and ride in a proper
seating position.
There is a lot that you and your passengers must
know and act accordingly to help the safety belts
and airbags do their job to provide supplemental protection .
A WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used .
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
-Always sit in an upright position and never
lean against the area where the supple-
mental side airbag is located.
- Never let a child or anyone else rest their
head against the side trim panel in the
area where the supplemental side airbag
inflates.
- Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the front seat
put their hand or any other parts of their
body out of the window.
- Always make sure that the side airbag can
inflate without interference.
- Never install seat covers or replacement
upholstery over the front seatbacks that have not been specifically approved by
Audi .
- Never use additional seat cushions that cover the areas where the side airbags de­
ploy .
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi­
ately by an authorized Audi dealer.
- Objects between you and the airbag can in­
crease the risk of injury in an accident by in­
terfering with the way the airbag unfolds or
216
-
by being pushed into you as the airbag in­
flates .
- Never place or attach accessories or other
objects (such as cup holders , telephone
brackets, or even large , bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the seat backrests.
- Such objects and accessories can become
dangerous projectiles and cause injury
when the supplemental side airbag de­ ploys.
- Never carry any objects or pets in the de­
ployment space between them and the
airbags or allow children or other passen­
gers to travel in this position .
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks .
- The airbag system can only be triggered
once . If the airbag has been triggered, the
system must be replaced by an authorized
Audi dealership.
- Damage (cracks, deep scratches etc.) to the
original seat covers or to the seam in the
area of the side airbag module must always
be repaired immediately by an authorized
Audi dealer .
- If children are seated improperly, their risk
of injury increases in the case of an accident
~ page 218, Child safety .
-Never attempt to modify any components of
the airbag system in any way .
- In a side collision, side airbags will not func­
tion properly if sensors cannot correctly
measure increasing air pressure inside the
doors when air escapes through larger, un­
closed openings in the door panel.
- Never drive with interior door trim panels
removed.
- Never drive when parts have been re­ moved from the inside door panel and the
openings they leave have not been proper­
ly closed.
- Never drive when loudspeakers in the
doors have been removed unless the speaker holes have been properly closed .

Wheels
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
proper ly .
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor ­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the Infotainment system
disp lay with an indicator light
RR and a message.
If only one tire is affected , the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load pressure) or after changing or replacing a tire on
your vehicle ¢
page 265 . The tire pressure moni­
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 256, fig.191.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low.
- the tire has structural damage .
- the tire was replaced or the tire pressure was
changed and it was not stored¢
page 265.
-the spare tire* is installed.

mm (T ire Pressure Monitoring System) Tire
pressure: malfunction! See owner's manual -
If
mm appears after switching on the ignit ion or
while driving and then the indicator light
RR in
the instrument cluster also starts to blink for
about one minute and then stays on permanent­ ly, there is a system malfunction. Try to store the
correct tire pressures¢
page 265. If the indica­
tor light does turn off or turns on again after a
short period of time , drive to an authorized A udi
dealer or authorized Audi Service Facility immedi ­
ate ly to have the ma lfunction corrected.
_& WARNING
-If the tire pressure indicator appears in the
disp lay, reduce your speed immediately and
avoid any hard steering or brak ing maneu­
vers. Stop as soon as poss ible and check the
tires and their pressure .
- The driver is responsible for maintain ing the
correct tire pressures . You must check the
tire pressures regularly .
- Under certain cond it ions (such as a sporty
driving style, w inter condit ions or unpaved
roads), the pressure monitor indicator may
be delayed.
- Do not use run-flat tires on your vehicle . Us­
ing them when not perm itted can lead to
vehicle damage or accidents.
(D Tips
- The tire pressure monitoring system can al­
so stop working when there is an ESC mal­
function.
- Us ing snow chains may result in a system
ma lfunction.
- The tires w ith the identification "AO"
¢
page 253 have been matched w ith your
Audi t ire pressure monitoring system. We
recommend that you use these tires.
