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
illustration=>
page 351, fig. 291 for the location of the label
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
fl ap) always takes precedence.
T he table below lists the recommended cold tire inflation pressures
for the Audi model covered by your Owner's Literature at the
