The engine oil and oil filter must be changed
according to the mi leage (kilometers) and
time interva ls specified in your vehicle's War
ranty & Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine o il can reduce engine performance and
can lead to expensive engine repairs.
Changing the o il at the recommended inter
vals is so very important because the lubricat
ing properties of oil decrease gradually during
normal vehicle use . If you are not sure when
you have your oi l changed, ask your author
i zed A udi Service Advisor.
Under some circumstances the engine o il
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, ope ra te the vehicle in dusty
areas or mostly under s top-and-go traffic con
d itions, or when yo u use your vehicle whe re
temperatures stay below freezing point for
l ong periods.
D etergen t additives i n the o il w il l make fresh
oil look dark after the eng ine has been run
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
Damage or malfunction s due t o lack of
m aintenance
It is essen tial that you change your oil at the

Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all
of its moving parts .
In order to provide effective lubrication and
cooling of interna l eng ine components, all in
te rnal combust io n engines consume a certain
amount of oil. Oil consumpt io n va ries from
engine to e ngine and may change sig nifican tly
ove r the life of the engine. Typically, engines
with a spec ified break -in pe riod (see
c::> page 158) consume more oil d uri ng the
break-in pe riod than they consume afte r oi l
consumption has stabilized.
U nder normal cond itions, the rate of oi l con
s u mption depends on t he q uality and viscos ity
of the oil, the RP M (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac
tors are the amount of oil dilut ion from water
condensa tion or fue l residue a nd the oxida
tion level of the oil. As any eng ine is subject to
wear as m ileage builds up, t he oil co nsump
t ion may increase over time until repla cement
of wo rn components may be come necessary.
Wi th a ll these va riab les coming into p lay, no
standard rate of oil consumpt io n can be es
t a bl is h ed o r spec ified . There is no alte rnative
to regular and frequent chec king of the o il lev

When charging at low voltages (e.g. with a
trickle charger), the battery cables do not
have to be disconnected first. Before charging
at
high voltages, i.e. "fast charging", you
must disconnect both cables. In either case,
follow the instructions from the manufacturer
of the charger .
Fastcharging a battery is
dangerous ¢.&. in
Working on the battery on page 185 .
It re
quires special charging equipment and the knowledge to go with it. We recommend hav
ing your battery fast charged only by a quali
fied workshop.
A discharged battery can
freeze at tempera
tures of only 32 °F (0 °C) . Allow a frozen bat
tery to thaw completely before attempting to
charge it¢ ,&. . However, we recommend not
using a thawed battery again because the bat
tery casing can be cracked due to ice forma
tion and can leak battery acid.
Do not open the battery caps when charging
the battery.
_& WARNING
-
Charging a battery can be dangerous.
- Never charge a frozen battery .
It may ex
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion , never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe
tent technician with the proper equip ment.
Checking and filling 187
- Battery acid that may spill during charg
ing should be washed off with a solution
of warm water and baking soda to neu
tralize the acid .
@ Note
Never use a fast charger as a booster to
start the engine. This will seriously dam
age sensitive electronic components, such
as control units, relays, radio, etc ., as well
as the battery charger .
(D Tips
-The vehicle battery must not be charged
with a standard small charger that plugs
into the cigarette lighter or outlet .
- Only charge the battery through the con
nections in the luggage compartment.
Replacing the battery
The new battery must have the same specifi
cations as the old one.
Your vehicle is equipped with an intelligent
energy management system for distributing
electricity ¢
page 155. The battery charges
better in vehicles with the energy manage
ment system than in vehicles without the sys
tem. To ensure that the additional power is
available after replacing the battery , replacing
with the same type of battery from the same
manufacturer (like the battery that was deliv
ered with the vehicle) is recommended. An au
thori zed dealer mus t code the battery in the
energy management control module .
T he new battery must have the same capacity,
voltage (12 volts), current and design and it
must be sealed with plugs. The battery must
conform to the standards TL 825 06 (from Oc
tober 2006) and VW 7 50 73 (from August 2001).
Since the vehicle battery is difficult to reach,
we recommend having the battery replaced by
an authorized Audi R8 dealer or other quali-
fied workshop . ..,. •

Tires and wheels 193
Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 150 Tire pressure label: located on driver's side B·
pillar
Tire pressure generally refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals (kPa), the interna
tional measuring unit and in pounds per
square inch (PSI). Tire pressure is based in
part on the vehicle's design and load limit
the greatest amount of weight that the vehi
cle can carry safely and the tire size. The prop
er tire pressure is frequently referred to as the
"recommended cold tire inflation pressure."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "cold." It is the
inflation pressure in a "cold" tire that counts.
Therefore, you should never let air out of a
warm tire to match "cold tire inflation pres
sure" recommendations. The tires would then be underinflated and could fail suddenly.
Maintaining proper tire pressure is one of the
most important things you can do to help
avoid sudden tire failure. Underinflated tires
are a major cause of sudden tire failure. Keep
ing tires at the right pressure is also impor
tant for safe and responsive vehicle handling,
traction, braking and load carrying .
Tire pres
sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci
ties approved for your vehicle.

MANUA L FOR
ADDITTONAL
INFOl
u
The recommended tire pressures for your Audi
depend on the kind of tires on your vehicle
and the number of passe ngers and/or amount
of luggage you will be transporting.
The tire pressure label located on driver's side
B-pillar 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
factured.
If you wish to improve comfort when operat
ing the vehicle at normal load (up to 2 occu
pants), you can adjust tire pressures to those
specified for normal vehicle load. Before oper
ating the vehicle at maximum load, you must
increase the tire pressures to those specified
for maximum vehicle load
9 .&.
Bear in mind that the tire pressure monitoring
system can only monitor the tire pressures
that are stored. The system does not recog
nize the load condition of your vehicle.
See the illustration,:;,
fig. 150 for the location
of the label on driver's side B-pillar (color of
the actual label and exact location on the ve
hicle 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 on driver's side B-pillar always
ta kes precedence. ..,.

Checking tire pressure
The correct tire pressure for the tires original
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil lar.
The recommended t ire pressures are on the
tire pressure label and in the table
r=> page 193, Cold tire inflation pressure . T his
means that the pressure must be checked and
a d ju sted when the tire has not been driven for
mo re than a couple of mi les (kilometers) at
l ow speeds during the p revious three hours.
Air in the tires expands when the tire heats up
as a result of internal fr iction as it flexes in
use. The tire pressure is higher when the tire
h as warmed up than when it is "cold".
It is the inflation pressure in a "cold" tire that
counts. Therefore, you shou ld never let air out
of a warm tire to match "Cold tire inflation pressure" recommendations
c> page 193 . The
tires would then be under infla ted and could
fa il suddenly.
The tire pressure label on yo ur Audi lists t he
recommended cold t ire inflat ion pressures for
the new, or igina l equipment tires that were
on you r vehicle at the t ime it was manufac
tured. For the location of the label
r=> page 193, fig. 150.
Most tires lose a ir natu rally over time. They
can also lose some a ir if you dr ive ove r a pot
hole o r hit a curb wh ile pa rking.
It is usua lly
not poss ib le to see whether the radial t ires
used today a re underin flated j ust by looking
at them.
Therefore, be sure to check tire pressures at
least o nce a month and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long". See r:=>page 196, Tires and vehicle
load limits for more important information.
Always use an accurate tire pressure gauge
when check ing and adjusting inflation pres
sures . Check all of the t ires. If the pressure in
Tire s an d wheel s 195
any tire is too high when the tire is "cold", let
air out of the tire slowly with the edge of the
tire ga uge and keep checking the pressure un
ti l yo u reach the pressure that is correct for
the load (passengers and luggage) and kind of
driv ing you plan to do .
If the pressure in any ti re is too low, note the
difference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
t h e ve hicle load (passenge rs and luggage) for
t h e tires on your vehicle as l isted on the o n
you r vehicle and in this ma nual a nd the k ind
of d riving you plan to do .
Never exceed the max imum inflation pres
sure li sted on the tire sidewall for any rea
s on.
Remember that the vehicle manufacturer, not
t h e tire manufactu rer, determines t he cor rect
ti re p ressu re fo r the tires on your ve hicl e.
It is important to check the t ire pressure when
the tires are co ld .
- Read the required tire pressure from the t ire
pressure labe l located on driver's side B-pil
lar.
- T urn the va lve stem cap counter-clockw ise
to remove it from the tire va lve.
- Place t he air pressure gauge on the va lve.
- The tire pressures should o nly be checked
and ad justed when the tires are co ld . The
slightly raised pressures of warm tires must
not be reduced.
- Adj ust the tire pressure to the load you are
carrying.
- Reinstall the valve stem cap on the va lve.
When should I check the tire pr essu re?
T he co rrect tire pressu re is especially impor
t a nt a t high speeds. The pressure should
therefore be checked at least once a month
and always before starting a jo urney .
When should I adjust the tire pressures ?
Adjust the tire pressure to the load you a re
ca rrying. After chang ing a wheel
or rep lacing .,..

soon as possible, and inflate them to the
proper pressure. Driving on a significant ly un
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation a l
so reduces fuel efficiency and tire tread l ife,
and may affect the veh icle 's handling and
stopping ab ility.
Please note that the TPMS is not a substitute
for proper t ire maintenance, and it is the dr iv
er's responsib ility to ma inta in correct t ire
p ress ure , even if under- inflation has not
reached the leve l to t rigger illumination of the
TPMS low tire pressure telltale .
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not ope rating properly. The
TPMS malfunc tion indica to r i s combined wi th
the low t ire p ressu re tell ta le. When the sys

Introduction
The tire pressure monitoring system monitors
air pressure in all four road wheels while the
vehicle is moving .
As soon as the tire pressu re mo nitor ing sys
tem senses a s ignificant loss o f air pressure in
one or severa l ti res, text messages and yellow
symbo ls appear in the instr ument cluster dis
p lay to alert the driver. The
[al warning light
Tire s an d wheel s 207
in the instrument cluster comes on when the
ti re is significant ly underinflated
Q page 34.
The wa rni ng lig ht [al also illu minates i n the
case of a system mal fun ct io n.
Be aware that t ire pressure is a lso dependent
o n the tempe ratu re of the t ire. For eve ry 18 ° F
(10 °C) incre ase in tir e te mper ature, tire pres
s u re inc reases by about 1.5 psi (0 .1 bar). The
ti re warms up while the vehicle is moving and
ti re p ress ure rises . So you sho uld ad just tire
pressure only when they a re
cold, when the
temperature of the tires is roughly the same
as the ambient a ir temperature.
In order to keep the tire press ure monitoring
system p roperly ca librated, t ire press ure on
all four tires sho uld be checked at regu lar in
terva ls.
The tire pressure is shown on the label located
on the dr iver's side B-pillar (v is ib le when the
door is open) .
A WARNING
When the tire pressure mo nitoring system
war ning light is lit , one o r more of your
tires is s ignificantly under-infla ted . You
shou ld stop and check your tires as soon as
pos sib le, and in flate t hem to the proper
p ress ure a s in dic ate d on the ve hicle's ti re
p ress ure lab el
¢page 19 3. D riving on a
significantly under -inflated ti re causes t he
tire to over heat and can lead to tire failure .
Under-inflat ion also is like ly to impair the
vehicle's handling and stopping ab ility.
@ For the sake of the environment
D riving wit h un der -inflated tires red uces
fuel efficiency an d tire t read life.
(D Tips

208 Tir es and whee ls
- The tire pressure monitoring system
helps the driver to keep an eye on tire
pressures. But the driver st ill has the re
sponsibility for maintaining the correct
tire pressure.
- Tire pressure must only be adjusted
when the temperature of the tires is
about the same as ambient air tempera
ture.
- When tires are replaced, the sensors and
valves should not be exchanged . The
valve core, nut, valve sealing and seal
washer (rep lacement kit) needs to be re
placed. If necessary, the valve and the
whee l electronics have to be rep laced.
- The tire pressure monitoring system on
your Audi was calibrated us ing tires w ith
"RO" identification. We recommend us
i ng these tires.
- If you should put different whee ls and
ti res on yo ur vehicle (e.g. w inter wheels
and tires), yo u m ust be certain that the
whee ls and tires are compatible with the
tire pressure monitoring system . Other
wise the system w ill reg ister a ma lfunc
tion and a fault message will be d is
played . For more information, contact
