AIRBAG RE­
PLACEMENT RECORD.
- Applies to plug-in hybrid* vehicles: In the
event of a collision where the airbags de­
ploy, the electrical connection to the high
voltage battery is automatically disconnect­
ed. This prevents a short c ircuit.
@) For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al - special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend 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 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-
.
Airbag system
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.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 240 Driver 's knee airbag
The driver knee airbag is in the instrument panel
underneath the steering
wheel¢ fig. 240, 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
t ion 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 2 79, 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
posit ion in a frontal collision so that the airbags
can provide supplemental protection .

Wheels
The grade C corresponds to a leve l of perform ­
ance which all passenger car tires must meet un­
der the Federa l Motor Vehicle Safety Standard
No.
109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The traction grade ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acce le rat ion, cor­
ne ring, hydroplaning or peak traction charac­
teristics.
A WARNING
Th e temperatu re grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separate ly or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire Pressure Monitoring System indicator
(J.) General notes
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
ve hicl e manufacturer on the vehicle placard or
tire in flat ion press ure label. ( If yo ur vehicle has
t ires of a different siz e than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those t ires) .
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your t ires is significant­
ly under-inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
348
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi ­
cant ly under-inflated t ire causes the t ire to over­
heat and can lead to tire fa ilure . Under-inflation
also reduces fue l eff iciency 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 dr iver's re­
spons ibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
su re te lltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating prope rly . The TPM S mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi ­
mately one minute and then remain continuously
illuminated. This sequence wi ll continue upon
s ub sequent vehicle start-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
l ow tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
i nstallation of replacement or alternate tires or
wheels on the veh icle that prevent the TPMS
from functioning properly. Always check the
TPMS ma lfunction telltale after replac ing one or
more tires or wheels on you r vehicle to ens ure
that the rep lacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.

system
(.L) 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 t ire 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
equ ipped w ith a t ire pressure monitoring system

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
p in g 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 leve l
to trigger illuminat ion of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped with a TPMS
malfunct ion indicator to indicate when the sys­

function indicator is combined with the low tire
pressure telltale. When the system detects a
350
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 tel ltale after replac ing 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.
Description
Applies to: vehicles with tire pressure monitoring system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tema
perature and pressure in the tires. The data is
sent from these sensors to the control module by
radio frequency .
The tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
¢ page 351. It also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored
¢ page 351.
The system does not detect if the stored tire
pressures match the recommended tire pres ­
sures . You must store the tire pressures again
¢ page 352:
- every time the tire pressures change, for exam ­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used.

Fuses and bulb s
