generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate-
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure > A.
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet un-
der the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.

ZA\ WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning or peak traction charac-
teristics.

ZA\ WARNING
The temperature 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 separately or
in combination, can cause heat buildup and
possible tire failure.

Z\ WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat-
ed.

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-
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.

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 tem-
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 234. 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 234.
The system does not detect if the stored tire
pressures match the recommended tire pres-
sures. You must store the tire pressures again in
each of the following situations > page 235:
— Each time the tire pressures change, for exam-
ple when the load in the vehicle changes
— After replacing a tire
— If wheels with new wheel sensors are used

ZX WARNING
—The tire pressure monitoring system assists
the driver in monitoring tire pressures. The [>

Driving in other
countries
Government regulations in the United States and
Canada require motor vehicles to comply with
emissions regulations and safety standards.
Therefore, vehicles that were produced for the
U.S. and Canadian markets are different from
vehicles produced for other countries.
If you plan to use your vehicle outside of the Unit-
ed States or Canada, it is possible that:
— Fuel may have a significantly lower octane rat-
ing. Unsuitable fuels can cause engine damage.
— Proper maintenance and repair work may not
be possible because special service equipment,
tools, or measuring devices needed for your ve-
hicle may not be available.
258
— Replacement parts may not always be availa-
ble.
— Navigation systems for vehicles built for the
U.S.A. and Canada will not necessarily work in
Europe, and may not work in other countries.
() Note
Audi is not liable for damage to the vehicle re-
sulting from these country-specific differen-
ces.
Maintenance, repairs,
and technical modifi-
cations
Observe the safety precautions > page 200, Gen-
eral information and > page 246, Raising the ve-
hicle.
General information
Due to the increasing complexity of technology in
these vehicles, as well as the safety and environ-
mental standards that apply, you can only per-
form a very limited amount of repairs and modifi-
cations to the vehicle yourself.
Proof of maintenance work may be required to
submit a claim within the warranty period.
We recommend that you have your vehicle serv-
iced by an authorized Audi dealer or authorized
Audi Service Facility and that Audi Genuine Parts
and Audi Genuine Accessories are used. This
helps to ensure that your vehicle's functionality,
performance, and safety are not impaired.
Maintenance and repairs
Your vehicle was designed to help keep mainte-
nance requirements to a minimum. Some regular
maintenance is required to help ensure that your
vehicle runs in a safe, economical, and reliable
manner. Please refer to your Warranty & Mainte-
nance Booklet for more detailed information
about vehicle maintenance.
When operating the vehicle under more extreme
operating conditions, for example when outside
temperatures are very low or in very dusty envi-
ronments, certain maintenance should be per-
formed between the specified intervals.

Accessories and technical changes

Usually maintenance and repair work requires
special tools, measuring devices, and other
equipment that is available to trained vehicle
technicians in order to help ensure that your vehi-
cle and all of its systems operate correctly, relia-
bly, and safely. Performing work on the vehicle
incorrectly can impair the operation and reliabili-
ty of your vehicle and may void one or more of
your vehicle's warranties.
Technical Modifications
Interference with electronic components, their
software, the wiring, and data transfer may cause
malfunctions. Because of the way electronic com-
ponents are interconnected, such malfunctions
can also impair systems that are not directly in-
volved. This means that you risk both a substan-
tial reduction in the operational safety of your ve-
hicle and increased wear of vehicle components.
Some convenience functions, such as the conven-
ience turn signal function, individual door open-
ing function, and displays, can be reprogrammed
using special workshop equipment. If functions
are reprogrammed, the information and descrip-
tions about these functions in this Owner's Man-
ual may no longer apply to the changed func-
tions. Audi recommends that an authorized Audi
dealer or authorized Audi Service Facility perform
and verify any reprogramming procedures.


— Never perform any work in the motor com-
partment unless you know exactly how to
carry out the job and have the correct tech-
nical information and the correct tools.
— If you are uncertain about what to do, have
the work performed by an authorized Audi
dealer, an authorized Audi Service Facility,
or another qualified workshop. Serious per-
sonal injury may result from improperly per-
formed work.


Z\ WARNING
Maintenance work, repairs, or technical modi-
fications to the vehicle (such as installing ad-
ditional equipment) that is not performed
correctly can cause serious injuries and in-
crease the risk of an accident.


ZA\ WARNING
The motor compartment in any motor vehicle
is a potentially dangerous area and can cause
serious personal injury.
— Always use extreme caution when doing any
work in the motor compartment. Always fol-
low commonly accepted safety practices and
use common sense. Never risk personal in-
jury.

@) Note
— Maintenance work, repairs, or technical
modifications to the vehicle (such as instal-
ling additional equipment) that is not per-
formed correctly can cause vehicle damage.
— If emergency repairs must be performed,
take your vehicle to an authorized Audi deal-
er or authorized Audi Service Facility as soon
as possible.
— Audi is not liable for damage to the vehicle
resulting from failure to comply with these
guidelines.
@) For the sake of the environment
— Regular maintenance can help protect the
environment.
— Technical modifications to the vehicle can
have a negative impact on fuel consumption
and vehicle emissions.
@) For the sake of the environment
Certain components in your vehicle such as
undeployed airbag modules, pretensioners
and remote control batteries may contain Per-
chlorate Material - special handling may ap-
ply, See www.dtsc.ca.gov/hazardouswaste/
perchlorate. When the vehicle or parts of the
restraint system including airbag modules
