& WARNING
Whenever working on the battery or on the electrical system ,
there is the risk of injury, accident and even fire . Read and heed the
following WARNINGS:
• Always wear eye protection . Do not let battery acid or any lead
particles get on your skin or clothing. Shield your eyes. Explosive
gases can cause blindness or other injury.
• Battery acid contains sulfuric acid . Sulfuric acid can cause
blindness and severe burns .
- Always wear gloves and eye protection. Do not tilt the battery because a cid could leak out of the ventilation openings .
- If you get battery acid in your eyes or on your skin, immedi ­
ately rinse with cold wate r for several minutes and get medical
attention .
- If you should ingest any battery acid, seek medical attention
immediately.
• Do not expose the battery to an open flame , electric sparks or
an open light.
• Do not smoke.
• Do not interchange the positive and negat ive cables .

• When a battery is charged , it produces h ydrogen gas which i s
explosive and could cau se personal injury .
• Always keep the battery well out of the reach of children.
• Before work is done on the electrical system , disconnect the
negative ground cable .
• Before performing any work on the ele ctri cal system , switch off
the engine and ignition as well as any electrical equipment. The negative cable on the battery m ust be disconnected . If you are ju st
going to replace a light bulb , then it is enough to switch off the
lights .
• Before disconnecting the battery , switch off the anti -theft
alarm system! Otherwise you will set off the alarm .
• When disconne cting the battery , first disconnect the negative
c able and then the positive cable .
• Before reconnecting the battery , make sure all electrical
c onsumers are swit ched off . Reconnect the positive cable first and
then the negative cable. Never interchange the cables - this could start a fire !
• Never charge a frozen or a thawed -out battery. It could
explode! If a battery has frozen , then it must be replaced . A
discharged battery can freeze over at 32 °F (0 °Cl.
• Make sure the vent hose is always attached to the opening on
the side of the battery.
• Never use batteries whi ch are damaged . There is the danger of
an explosion! Always replace a damaged battery.

Battery replacement
The new battery must have the same specffications and
dimensi ons as the original equipment battery.
Intel ligen t energy management in your vehicle is responsible for
distributing the e lectrica l ene rgy throughout your vehicle
::} page 295. The intelligent energy management system will keep
the engine battery charged bette r then vehicles wi thou t this system .
To make sure the additional electrical energy is available once again
after you have changed the batte ry, we recommend that you install
batteries of the same type and manufacture only (the same as those
installed at the time your vehicle was delivered). Specifications are
listed on the battery housing . Your authorized Audi dealer will then
code the battery management cont rol unit .
If i t is no t possib le to use a ba ttery o f this type, the new battery m ust
have the same capacity, vo ltage (12 volts), amperage, construction
and plug seal ing.
When installing the battery, make sure the ignition and all electrica l
consumers are turned off .
0 Note
Make sure the ventilation hose on the side of the bat tery is
connected, otherwise fumes or battery acid can leak out .
W For the sake of the environment
Because of the problem of proper d isposal of a battery , we recom­
mend your authorized Aud i dea ler change the battery for you .
Ba tteries contain sulfuric acid a nd lead and must always be
disposed of properly in compliance with all environmental regula ­
tions. D isposi ng o f vehicle ba tteries i mproper ly is very dangerous to
the environment .•

Bear in mind that the tire pressure monitoring system can only
monitor the tire pressures you have stored. The system does not
recognize the load condition of your vehic le.
The effectiveness of the tire pressure monitoring system will be impaired if you store normal load pressures but then operate the
vehic le at its maximum load=>&. See the

either on driver's side B -p illar or inside the fuel fi ller flap (color of
the actual label and exact location on the vehicle will vary slight ly).
Note that the fol lowing tab le is accurate at the time of going to
press and is subject to change . In the event of discrepanc ies, the tire
pressure label (On USA vehic les, the tire pressure label is located on
the driver's s ide B-pillar . On Canada vehicles, the tire pressure label
is located either on the driver's side B-pillar or inside the fue l fi ller

ment tires that were on your vehicle at the time it was manufac­
tured. For the location of the labe l =>
page 351, fig. 291 .
Most tires lose air natural ly over time. They can also lose some air if
you drive over a pothole or hit a curb while parking. It is usually not
possible to see whether the radial tires used today are underinflated
just by looking at them.
Therefore, be sure 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 consider to be
"long." See=>
page 355, "Tires and vehicle load limits" for more
important informat ion .
Always use an accurate tire pressure gauge when checking and adjusting inflation 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 tire is "cold," let air out of the tire slowly with the edge of the tire
gauge and keep checking 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.
If the pressure in any tire is too low, note the difference between the
pressure in the cold t ire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehic le as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do .
Nev er e xceed th e m ax imum inf lation p ressu re li sted on the tir e
s id ew all for any re ason .
Remember that the veh icle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle .
It is important to check the ti re pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label. On
USA vehicles, the tire pressure label is located on the driver's side
B-pillar. On Canada vehicles, the tire pressure label is located either
on the driver's s ide 8 -pillar or inside the fue l fil ler flap . The tire pres -sure labe
l lists the recommended co ld tire inflation pressures for
t he vehicle at its maximum capaci ty weight and the tires that were
on your vehicle at the time it was manufactured. For recommended
tire p ressures for normal load conditions, please see chapter
=>
page 351 .
• Turn the va lve stem cap counter -clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve.
• T he tire pressures should only be checked and adjusted when
the tires are cold . The s lightly raised pressures of war m tires must
not be reduced.
• Adjust the tire pressure to the load you are carrying .
• Reinstal l the valve stem cap on the valve.
Wh en sh o uld I ch eck th e tir e pr es su re?
The correct tire pressure is especially important at high speeds. The
pressure should therefore be checked at least once a month and
always before starti ng a journey . Do not forget to check the tire pres ­
sure for the spare wheel.
When should I adjust the tire pre ssures ?
Adjust the tire pressure to the load you are carrying . After changing
a whee l
or replacing whee ls you have to adjust the tire pressures on
all wheels. In addition, you must then initialize the new tire pres­
sures in the tire pressure monito ring system =>
page 42.
& WARNING
Incorrect tire pre ssure s and /or underinflation can lead sudden tire
fa ilure , loss o f control , colli sion , seriou s per so nal inj ury or e ven
death.
