Is this an offroad vehicle?
Your Audi is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.

ZA\ WARNING
— Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci-
dent.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be-
cause this increases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane’” if driving at speeds that
are too high. Unlike front wheel drive vehi-
cles, the engine RPM does not increase sud-
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci-
dent.

Rear spoiler
Applies to: vehicles with retractable rear spoiler
The extendable rear spoiler increases driving sta-
bility.

Automatic mode (normal operation)
— Automatic extension: the rear spoiler will auto-
matically extend when speeds exceed approxi-
mately 75 mph (120 km/h).
— Automatic retraction: the rear spoiler will auto-
matically retract when speeds decrease to un-
der approximately 50 mph (80 km/h).
Manual mode

button to fully extend the rear spoiler.
— Retracting manually: when driving at speeds
below approximately 10 mph (20 km/h), press
and hold the button to retract the rear spoiler.
When at speeds between 10 mph (20 km/h)
and 75 mph (120 km/h), the rear spoiler will
completely retract when you tap the button.
Indicator lights
8 / | Rear spoiler: malfunction! Please con-
tact Service
The rear spoiler may not have extended due toa
malfunction. This could change the vehicle's driv-
ing characteristics at high speeds. Do not drive
faster than 85 mph (140 km/h). Drive to an au-
thorized Audi dealer or authorized Audi Service
Facility immediately to have the malfunction cor-
rected. The color of the indicator light depends
on the vehicle speed.

ZA WARNING
Driving at higher speeds without the rear
spoiler deployed can impair handling charac-
teristics, making the vehicle harder to control.
— 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.

Airbag system

— when the electrical capacitance measured by
the capacitive passenger detection system for
the front passenger seat indicates that the pas-
senger side frontal airbag must be switched off
by the electronic control unit (the PASSENGER
AIR BAG OFF %; light > page 200 and how they
work comes on and stays on).


ZA\ 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 airbag can be seriously in-
jured by an airbag as it unfolds with great
force in the blink of an eye > page 190.

Z\ WARNING
A child in a rearward-facing child seat instal-
led on the front passenger seat will be seri-
ously injured and can be killed if the front air-
bag inflates - even with an Advanced Airbag
System.
— The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
— Never install a rearward facing child safety
seat on the front passenger seat unless the
PASSENGER AIR BAG OFF %; light comes
on and stays on. If the PASSENGER AIR
BAG OFF #%; light does not come on and stay
on, the inflating airbag will hit the child
safety seat or infant carrier with great force
and will smash the child safety seat and
child against the backrest, door or roof.
Have the airbag system inspected immedi-
ately by your authorized Audi dealer.

ZA WARNING
Objects between you and the airbag will in-

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 personal injury if the airbags
inflate.
— Never place or attach accessories or other
objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked
“AIRBAG” on the steering wheel, instrument
panel, seat backrests or between those
areas and yourself. These objects could
cause injury in a crash, especially when the
airbags inflate.
— Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front air-
bag during braking or in a sudden maneuver.
Objects near the airbags can become projec-
tiles and cause injury, particularly when the
seat is reclined.
— Never place or transport objects on the front
passenger seat. Objects on the front passen-
ger seat could cause the capacitive sensor in
the seat to signal to airbag system that the
seat is occupied by a person when it in fact is
not, or that the person on the seat is heavier
than he or she actually is. The change in
electric capacitance because of such objects
can cause the passenger front airbag to be
turned on when it should be off, or can
cause the airbag to work in a way that is dif-
ferent from the way it would have worked
without objects on the seat.
— Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is
not, or to signal that it is occupied by some-
one who is heavier than the person actually

from the airbag as possible. The backrest
must be adjusted to an upright position.
Make sure that the PASSENGER AIR BAG
OFF %; light comes on and stays on all the
time whenever the ignition is switched on.


ZA 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, have the airbag system in-
spected by your Audi dealer before transport-
ing anyone on the front passenger seat.

@ Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side will be turned off, and the PASSENGER
AIR BAG OFF 3; light will stay on.
Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov-
ing, 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.
There are some important things you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
components do not cause injury or pollute the
environment.

ZA WARNING
Improper care, servicing and repair proce-
dures can increase the risk of personal injury
and death by preventing an airbag from de-
ploying when needed or deploying an airbag
unexpectedly:
— Never cover, obstruct, or change the steer-
ing wheel horn pad or airbag cover or the in-
strument panel or modify them in any way.
— Never attach any objects such as cup holders
or telephone mountings to the surfaces cov-
ering the airbag units.


— For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois-
tened 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 deploy and protect
properly.
— Never repair, adjust, or change any parts of
the airbag system.
— All work on the steering wheel, instrument
panel, front seats or electrical system (in-
cluding 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 au-
thorized Audi dealer or qualified workshop.
— 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 replacement
upholstery over the front seatbacks that
have not been specifically approved by Au-
di.
— Never use additional seat cushions that
cover the areas where the side airbags in-
flate.
— 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.
— The airbag system can deploy only once. Af-
ter an airbag has been deployed, it must be
replaced with new replacement parts de-
signed and approved especially for your Audi
model version. Replacement of complete
airbag systems or airbag components must
be performed by qualified workshops only.
Make sure that any airbag service action is
entered in your Audi Warranty & Mainte-
nance booklet under AIRBAG REPLACEMENT
RECORD.
— For safety reasons in severe accidents, the
alternator and starter are separated from


203

Airbag system


the vehicle battery with a pyrotechnic circuit
interrupter.
— Work on the pyrotechnic circuit interrupter
must only be performed by a qualified
technicians who have the experience, in-
formation and special tools necessary to
perform the work safely.
— If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions

must be followed.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs ina 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.

Z\ 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 ina
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.

Knee airbags
Pye al) CooL Aide}
The knee airbag system can provide supplemen-
tal protection to properly restrained front seat
occupants.

Fig. 159 Driver's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering wheel > fig. 159, the
airbag for the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers additional protection to
the driver's and passenger's knees and upper and
lower thigh areas and supplements the protec-
tion provided by the safety belts.
If the front airbags deploy, the knee airbags also
deploy in frontal collisions when the deployment
threshold stored in the control unit is met
= page 198, More important things to know
about front airbags.
In addition to their normal safety function, safe-
ty belts help keep the driver or front passenger in
position in a frontal collision so that the airbags
can provide supplemental protection.
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 airbag system can only help to
protect you if you are wearing your safety belt
and wearing it properly. This is why you should al-
ways wear your safety belt, not just because the
law requires you to do so > page 182, General
notes.

Child safety

PNW ete miele laste Relea meal Cele)
Your vehicle is equipped with a front “Advanced
Airbag System” in compliance with United States
Federal Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Vehicle Safety
Standard (CMVSS) 208 as applicable at the time
your vehicle was manufactured.
The Advanced Airbag system in your vehicle has
been certified to meet the “low-risk” require-
ments for 3- and 6-year old children on the pas-
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the risk of injury through interaction with
the airbag that can occur, for example, by being
too close to the steering wheel and instrument
panel when the airbag inflates. In addition, the
system has been certified to comply with the
“suppression” requirements of the Safety Stand-
ard, to turn off the front airbag for infants up to
12 months who are restrained on the front pas-
senger seat in child restraints that are listed in
the Standard.
Even though your vehicle is equipped with an Ad-
vanced Airbag system, a child should always ride
in the seat properly restrained for its 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
larger child in a rearward-facing seat.
The vehicle's Advanced Airbag System has a ca-
Pacitive passenger detection system in the front
passenger seat cushion that can detect the pres-
ence of a baby or a child ina child restraint sys-
tem on this seat.
The capacitive passenger detection system regis-
ters the changes that result in an electrical field
when a child, a child restraint, and a baby blanket
are on the front passenger seat. The change in
the measured capacitance due to the presence of
a child, a child restraint, and a baby blanket on
the front passenger seat is related to the child re-
straint system resting on the seat. The measured
capacitance of a child restraint system varies de-
212
pending on the type of system and specific make
and model.
The electrical capacitance of the various types,
makes, and models of child restraints specified
by the U.S. National Highway Traffic Safety Ad-
ministration (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys-
tem control unit together with the capacitances
typical of infants and a 1-year old child. When a
child restraint is used on the front passenger seat
with a typical 1 year-old infant, the Advanced Air-
bag System compares the capacitance measured
by the capacitive passenger detection system
with the data stored in the electronic control
unit.
Ce CM eee ANC Micra lia elle)
system
Regardless of the child restraint that you use,
make sure that it has been certified to meet Safe-
ty Standards and has been certified by its manu-
facturer for use with an airbag. If in exceptional
circumstances you must use it on the front pas-
senger seat, carefully read all of the information
on child safety and Advanced Airbags and heed
all of the applicable WARNINGS. Make certain
that the child and child restraint are correctly rec-
ognized by the capacitive passenger detection
system in the front passenger seat, that the front
passenger airbag is turned off, and that the air-
bag status is always correctly signaled by the
PASSENGER AIR BAG OFF #; light.
Many types and models of child restraints have
been available over the years, new models are in-
troduced regularly incorporating new and im-
proved designs and older models are taken out of
production. Child restraints are not standardized.
Child restraints of the same type typically have
different
weights and sizes and different “foot-
prints”, the size and shape of the bottom of the
child restraint that sits on the seat, when they
are installed on a vehicle seat. These differences
make it virtually impossible to certify compliance
with the requirements for advanced airbags with
each and every child restraint that has ever been
sold in the past or will be sold over the course of
the useful life of your vehicle.

hicle load.
—Overloading can lead to loss of
vehicle control and increase
the risk of an accident. Read
and follow the important safe-
ty precautions in > page 252,
Tires and vehicle load limits.
—The tire must flex more if the
tire pressure is too low or if

tion also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire

malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
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
properly.

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 circumference
and vibration characteristics of the individual
tires. If the pressure changes in one or more
tires, this is indicated in the Infotainment system
display with an indicator light @ and a message.
If only one tire is affected, the location of that

Tire pressure monitoring
system
(1) General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
