latched in place.
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per ­
sonal injury in the event of hard b raking or an
accident . To help reduce the risk of serious
personal in jury:
- Always put objects, fo r example, luggage o r
other heavy items in the luggage compart­
ment.
- Always sec ure objects in the luggage com­
partmen t using the tie-down hooks an d
s u itable straps.
A WARNING
Heavy loads wi ll influence the way yo ur vehi­
cle handles. To he lp reduce the ris k of a loss
of contro l leading to serio us pe rsonal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
- Always d istribute the load as evenly as
possible.
- Place heavy objects as far forward in the
luggage compartment as poss ible .
- Never exceed the Gross Axle Weight Rating or the Gross Vehicle Weight Rat ing specified
on the safety compliance sticker on the driv­
er's side B-p illar. Exceeding permissible
we ight s tanda rds can cause the vehicle to
slide and handle differently .
- Please obse rve information on safe driving
~page 1 2 9.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed wh ile driving.
- Never transport objects larger than those
fitt ing completely into the luggage area be­
cause the rear lid can not be fully closed.
-
Dri ving saf ety
- If you absolutely m ust dr ive with the rear lid
open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Open all a ir outlets in the instrument pan-
el,
- Switch
off the air rec irculat ion,
- Set the fresh air fan to the highest speed.
A WARNING
=
A lways make su re that the doo rs, all win-
dows, the powe r roof* and the rea r lid are se­
curely closed and locked to reduce the r isk of
i njury when the veh icle is not being used .
- After closing the rear lid , always make sure
that it is properly closed and locked .
- Never leave your veh icle unattended espe­
cially with the rear lid left open . A child
could crawl in to the vehicle th rough the lug­
gage compartment and close the rea r lid be­
coming trapped and unab le to get o ut. Be­
ing trapped in a vehicle c an le ad to ser ious
pe rsonal injury.
- Never let children play in o r around the vehi­
cle .
- Never let passengers ride in the luggage
compa rtment. Vehicle occupants mus t al­
ways be p roperly restrained in one of the ve­
h icle's seat ing pos itions.

Wheels
-Only use tires that are more than six years old when abso­lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on your vehicle. Using them when not permitted can lead to
ve­
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al­low enough a ir circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
l) Obey any applicable regulations in your
country.

-Driving qu ickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quick ly.

A WAR NING
-
Overloading a vehicle can cause
loss of vehicle contro l, a crash
or other accident, serious per­
sonal injury , and even death .
-Carrying more weight than your vehic le was designed to
carry will p revent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been over loaded may not
be able to stop the veh icle
within a safe dis tance .
-Tires on a vehicle that has been overloaded can fail sud­
d en ly , including a blowout and
sudden deflation, causing loss
of control and a crash .
-Always make su re that the to­
tal load being transported -
includ ing the weight of a trail ­
er hitch and the tongue
we ight of a loaded trailer -
d oes not make t he vehicle
heavier than the vehicle's

Determining correct load
limit
Use the example below to calcu ­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload­
ed .
Steps for Determining Correct
Load Limit
1 . L ocate the statement " THE
COMB INED W EIGH T OF OCCU­
PANTS AND CARGO S HOU LD
NEVER EXCEED XXX KG OR XXX
L BS" on your vehicle's placard
(tire inflation pressure label)
¢ page 215, fig. 189 .
2. Determine the combined
weight of the driver and pas­
sengers that w ill be riding in
your vehicle .
3 . Subtract the combined weight
of the driver and passengers
from
" XXX " kilog rams or " XXX "
pounds shown on the sticker
¢page 215, fig. 189 .
4. T he resulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample , if the
"XXX " amount

Wheels
- Traction AA A B C
- T emperature ABC
Quality grades can be found where appl icable on
the tire side wall between tread shoulder and
maximum section width
~ page 206, fig. 187.
For example: Tread wear 200, Traction AA, Tem ­
perature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under contro lled conditions on a specified gov ­
ernment test course.
F or examp le, a tire graded
150 would wear one
and one half (1 1/2) times as well on the govern­
ment course as a tire graded
100.
The relative performance of tires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
d ifferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. T hose grades represent the tire's
abi lity to stop on wet pavement as measured un ­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
~ .&..
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to d iss ipate
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 excess ive temperature can lead to sudden
tire
fa ilure ~.&. .
The grade C corresponds to a level of perform ­
ance which a ll passenger car tires must meet un-
222
der the Federal 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 tract ion grade assigned to this t ire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics .
A WARNING
The temperature grade for this tire is estab­
lished for a tire tha t 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.
A WARNING
-
-
Temperature grades apply to tires that are
proper ly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
ill General notes
Each tire, including the spare (if prov ided),
shou ld 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 veh icle has
t ir es of a diffe rent size t han the size ind icated on
the vehicl e placard or tire infl ation press ure la ­
bel, you sho uld determine the proper tire infla­
tion pressure for those tires).
As an added safety featu re, you r vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell ­
ta le when one or more of your tires is significant­
l y under-inflated. According ly, w hen the low tire
pressure telltale illuminates, you should stop and
check your t ires as soon as possible, and inflate
them to the proper pressure. Dr iving on a

overheat and can lead to tire failure. Under-inf la­
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 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 che ck 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.

ill 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.

Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he 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.
T he Tire Pressure Monitoring System shows the
current pressures and temperatures of the tires
in the Infotainment system
¢page 226. It also
compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is
stored ¢ page 226 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 226:
- 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.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an authorized Audi dealer or
authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authori zed Audi Service Facility.
