General information
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are neces­
sary, how they work and how to adjust and wear
them correctly.
~ Read all the information that follows and heed
all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death.
- Safety belts are the single most effective
means available to reduce the risk of serious
injury and death in automobile accidents.
For your protection and that of your passen­
gers, always correctly wear safety belts
when the vehicle is moving.
- Pregnant women, injured, o r physically im­
paired persons must also use safety belts.
Like all vehicle occupants, they are more
likely to be seriously injured if they do not
wear safety belts. The best way to protect a
fetus is to protect the mother -throughout
the entire pregnancy.
Number of seats
Your Audi has a total of five seating positions:
two in the front and three in the rear. Each seat­ ing position has a safety belt.
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death.
- Never strap more than one person, includ­
ing small children, into any belt.
It is espe­
cially dangerous to place a safety belt over a
child sitting on your lap.
- Never let more people ride in the vehicle
than there are safety belts available.
Safety belts
-Be sure everyone riding in the vehicle is
properly restrained with a separate safety
belt or child restraint.
~ Safety belt warning light
Your vehicle has a warning system for the driver
and front seat passenger (on USA models only)
to remind you about the importance of buckling­
up .

New tires or wheels
Audi recommends having all work on tires or wheels performed by
an author ized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace­
ment parts.
.,.New tires do not yet have the
optimum gripping properties. Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
.,.Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
Wheels
differently even if they are the
same size¢.&,. .
.,. If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase¢ .&,..
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
so only use the spare tire* tempo­
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all whee l dr ive
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the drive system is not damaged by
different tire speeds. For this rea­
son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires. ,..

Wheels
&,. WARNING -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when
218
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al­low enough air circulation to
cool the brake system. If they do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 189 Tire profile: treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Dr iving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty chec k the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
i.

-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much . This increases the
risk of an accident because it
can cause the tire to burst and result in loss of vehicle con­
trol.
-Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident .
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.

Tire pressure that is too low in­
creases fuel consumption .
Audi recommends using the
tire pressure specified for a normal load

when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label

Wheels
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.
A 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.
A 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.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
CD 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
228
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 tel ltale.
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 t ire
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 veh icle 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.
