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

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.

After changing a wheel
A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 120 ft lb (160 Nm).
- Have t he flat tire
replaced as soon as possible.
[ i] Tips
• I f you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque .
• Drive at reduced speed until you have the tightening torques
checked .•

- Let the compressor run until it has reached 50 PSI (3.5
bar). Switch the compressor off after running for 8
minutes at the most -danger of overheating!
& WARNING
The compressor and the tire filler hose can become extremely hot
while they are running -danger of burns!
0 Note
Switch the compressor off after running for 8 minutes at the most -
danger of overheating! Allow the compressor to cool down for a few
minutes before you use it again.
[ i] Tips
The compressor must not be connected to the cigarette lighter
socket, as this socket does not provide the required power .•
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern intended for use
in a specific direction
When using a spare tire with a tread pattern intended for use in a
specific direction, please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direction, use
the spare tire only temporarily since the tire will not be able to
achieve its optimum performance characteristics with regard to
aquaplaning, noise and wear. •
We recommend that you pay particular attention to this fact
during wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible to restore the handling advantages of a
unidirectional tire. •
Notes on wheel changing
Please read the information => page 359, "New tires and replacing
tires and wheels " if you are going to use a spare tire which is
different from the tires on your vehicle.
After you change a tire :
• Check the tire pressure on the spare immediately after installa­
tion.
• Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a
qualified workshop.
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 120 ft lb (160 Nm).
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speeds .
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed, then be sure to read
the information
