Command overview
information
Appl ies to: vehicles with voice recognition system
The following overv iews describe the comma nds
that can be used to operate the MMI using the
voice recognition system. ..,.

Airbag syste m
the system inspected immediately 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 should.
A WARNING
If the front airbag inflates, a child without a
child restra int, or in a rearward-facing child
safety seat, or in a forward-facing child re­
straint that has not been properly installed
w ill be seriously injured and can be killed.
- If you must install a rearward-fac ing child
seat on the front passenger seat because of
exceptional c ircumstances and the
PA SSEN ­
G ER AIR BAG OFF,;;
light does not appear
and stay on, have the airbag system inspect­
ed by your Audi dealer.
- If, in exceptional circumstances, you must
install a forward-facing chi ld restraint on
the front passenger seat, always move the
seat into its rearmost pos ition in the seat's
fore and aft adjustment range, as far away
from the airbag as possible. The backrest
must be adjusted to an upright posit ion.
Make s ure that the PASSENGER AI R BAG
OFF ,;;
light comes on and stays on a ll the
t ime whenever the ignition is switched on.
A WARNING
If the PAS SENGER AIR BAG OFF~; light does
not go out when an adult is s itting on the
front passenger seat afte r taking the steps
described above, have the airbag system in­
spected by your Audi dealer before transport­
ing anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenger
side w ill be turned off, and the
PA SSENGER
AIR BA G OFF ~;
light will stay on.
Repair, care and disposal of the airbags
Parts of the a irbag system are installed at many
d ifferent places on your Aud i. Instal ling, remov-
210
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 work ing properly
i n a coll is ion.
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.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal injury
and death by preventing an airbag from de­
p loying when needed or deploy ing an a irbag
unexpectedly:
-
- Never cover, obstruct, or change the steer­
ing wheel ho rn pad or airbag cover or the in­
strumen t panel or modify them in any way.
- Never attach any objects such as cup ho lde rs
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instr ument
panel, use only a soft, dry doth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag cannot deploy and protect proper ly.
- Never repair, ad just, or change any parts of
the airbag system.
- All work on the steering wheel, inst rument
panel, front seats or e lectr ica l system (in­
cluding the installation of audio equ ipment,
cellular te lephones and CB radios, etc.)
m ust be perfo rmed by a qualified techn ician
who has the training and spec ial equipment
necessary.
- For any work on the airbag system, we
strong ly recommend tha t you see you r au­
thori zed A udi dealer or qualified wo rkshop.
- Never modify the front bumper or pa rts of
the vehicle body.
- Always make sure that the side a irbag can
inflate w ithout interfe rence:

Child safety
Advanced front airbag system and children
Your vehicle is equipped with a front "Advanced
Airbag System" in compliance with United States Federal Motor Vehicle Safety Standard (FMVSS)
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 in a child restraint sys­
tem on this seat.
The capacitive passenger detection system regis­
ters the changes that result in an electrical field
when a ch ild, 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
restraint system resting on the seat. The meas­
ured capacitance of a child restraint system var­ ies depending on the type of system and specific
make and model.
220
The electrical capacitance of the various types, makes, and models of child restraints specified
by the U.5 .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 Ad­
vanced Airbag System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the electronic con­
trol unit.
Child restraints and Advanced front airbag
system
Regardless of the child restraint that you use,
make sure that it has been certified to meet Unit­
ed States Federal Motor Vehicle Safety Standards
and has been certified by its manufacturer for
use with an airbag. If in exceptional circumstan­
ces you must use it on the front passenger seat,
carefully read all of the information on child safe­
ty and Advanced Airbags and heed all of the ap­
plicable WARNINGS. Make certain that the child
and child restraint are correctly recognized by the
capacitive passenger detection system in the
front passenger seat, that the front passenger
airbag is turned off, and that the airbag 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. ..,.

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

- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station .
- With steel and alloy wheel rims, the wheel
bolts are cor rectly tightened at a torque of
90 ft lb (120 Nm) .
-If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque .
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi ­
ble. Remount the wheel cover .
