The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
The tire pressure label located either on driver's side 8-pillar or
inside the fuel filler flap on your Audi lists the recommended cold
tire inflation pressures for the vehicle at its maximum capacity
weight and tires that were on your vehicle at the time it was manu­
fac tured .
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants), you can adjust tire pressures to
those specified for normal vehicle load. Before operating the vehicle at maximum load, you must increase the tire pressures to those
specified for maximum vehicle load
~ & .
If your vehicle is equipped with a tire pressure monitoring system*,
bear in mind that the system can only monitor the tire pressures you have stored
. The system does not recognize the load condition of
your vehicle.
The effectiveness of the tire pressure monitoring system will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum
load~& .
See the illustration~ page 297, fig . 217 for the location of the label
either on driver's side 8-pillar or inside the fuel filler flap (color of
the actual label and exact location on the vehicle will vary slightly).
Note that the following table is accurate at the time of going to
press and is subject to change . In the event of discrepancies, the tire
pressure label (e ither on driver's side 8 -pillar or inside the fuel filler
flap) always takes precedence.
The table below lists the recommended cold tire inflation pressures
for the Audi model covered by your Owner's Literature at the
vehicle's capacity weight and the tire si zes installed on the respec­
tive models as original equipment, or as a factory option.

The tire pressure label on your Audi lists the recommended cold tire
inf lation pressures for the new, original equipmen t tires that were
on your vehic le at the time it was manufactured . For the location of
the
labe l=> page 297, fig. 217 .
Most tires lose a ir natural ly over time. They can a lso lose some air if
you drive over a potho le or hit a curb wh ile parking. It is usually not
possible to see whether the radial t ires used today are under inflated
just by looking at them.
Therefore, be su re to check tire pressures at least once a month and
always before going on a long trip . Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you wou ld not cons ider to be
" long ."
See => page 301, "Tires and vehicle load limits" for more
important i nformation .
A lways use an accurat e tire pressure gaug e when checking and
adjusting inflat ion pressures. Check a ll of the tires and be sure not
to forget the spare tire . If the pressure in any tire is too high when
the t ire is "cold," let air o ut of the t ire slowly with the edge of the tire
gauge and keep check ing the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you p lan to do .
I f the pressure in any tire is too low, note the difference between the
pressure in the co ld tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) fo r the t ires on your veh ic le as listed on
the on your vehicle and in this manual and the kind of driving you pl an to do .
Never exceed the m aximum inflation pressure li sted on the tire
s idewall for an y re ason .
Remem ber that the vehic le manufacturer, not t he tire manufacturer,
determines the correct tire pressure for the tires on your vehicle .
I t is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the t ire pressure label
located either on driver 's side B -pillar or inside the fuel fi ller flap . •
Turn the va lve stem cap counter -clockwise to remove it from the
t ire valve .
• Place the air pressure gauge on the valve.
• The tire pressures should only be checked and adjusted when
the tires are cold. The s lightly raised pressures of warm tires must
not be reduced.
• Adjust the tire pressure to the load you are carrying.
• Reinstal l the va lve stem cap on the valve .
When should I check the tire pressure?
The correct tire pressure is especially important at high spe eds . The
pressure should the refore be checked at least once a mo nth and
a lways before starting a journey. Do not forget to check the tire pres ­
sure for the spare whee l
=> page 317.
Wh en should I adjust th e tir e pre ssur es?
Adjust t he tire pressure to the load you are carry ing . After changing
a wheel
o r replacing whee ls you have to ad just the tire pressures on
a ll whee ls . In addition, on vehicles w ith tire pressure monito ring
system* you must then store the new tire pressures in the system
=> page 45.
& WARNING
Incorrect tire pre ssure s and /or underinflation can lead sudden tire
f ai lure , loss of control , collision , seri ous per sonal injury or even
death.
• When the w arning symbol
(l) appe ars in the in strument
clu ster , stop and inspect the tire s.
• Incorrect t ire pres sure and /or underinflat ion can cause
increa sed tire wear and can affect the handling of the vehicle and
s topping ability.
• Incorrect tire pres sures and /or underinflation can also lead to
s udden tire fa ilure , inc luding a blowout and sudden defl ation ,

Replacing light bulbs
For your safety, we recommend that you have your autho ­
rized Audi dealer replace any bulbs for you.
I t is becoming increasing ly more and more difficult t o replace
vehic le light bulbs since in many cases, other parts of the car must
first be removed before yo u are able to get to the bu lb . T his applies
especia lly to the ligh t bu lbs in the front of your car which you can
only reach th rough the eng ine compartment.
Sheet metal and bulb ho lders can have sharp edges that can cause
s e rious cuts, and parts must be correctly taken apart and th en prop­
erly put back together to help prevent breakage of par ts and long
te rm damage from water that can enter housings that have not
been properly resealed .
For your safety , we recommend that you have your authorized Audi
dea ler replace any bulbs for you, since your dealer has the prope r
tools, the correct bulbs and the expertise .
Gas di sc harge l amp s (x enon l ight s)*:
Due to the h igh e lectrical voltage, have t he bu lbs replaced by a qual ­
ified technician . Head lights with xenon light are identified by the
high voltage sticker .
& WARNING
Changing xenon lamps without the ne cessary equipment c an
c au se seriou s per sonal injury .
• Bulb s are pres surized and can explode when being changed.
Potential ri sk of injur y!
• On vehicle s equipped with ga s di scharge bulb s (xenon ligh t)*
