an open l ight .
• Do not smoke.
• Do not interchange the positive and negative cables .
• When working on the batte ry , be sure not to short -circuit the
terminals with tools or other metal objects . This would cause the
battery to heat up very quickly , whi ch could lead to damage or
explosion and personal injury .
• When a battery is charged , it produces hydrogen gas which is
explosive and could cause personal injury .
• Always keep the battery well out of the reach of children .
• Before work is done on the electrical system, disconnect the
negat ive ground cable .
• Before performing any work on the electrical system , switch off
the engine and ignition as well as any electrical equipment . The
negative cable on the battery must be disconnected . If you are just

Charging of battery 6 -cylinder engine )
All work on the battery requires specialized knowledge!
The battery is maintenance-free and is inspected regu ­
larly as part of vehicle service.
If starting problems occur because the battery charge is too low,
this may indicate a defective battery. In this case we recommend
having a qualified workshop inspect and charge the battery or
replace it if necessary. A discharged battery can
freeze at tempera ­
tures of only O °C. A thawed battery must be replaced, as the battery
housing may be cracked due to freezing and could therefore leak
acid.
Charging the battery
Battery charging should be performed by a qualified workshop,
since batteries employing a special technology are used which
require current-limited constant voltage charging.
0 Note
The vehicle may be optionally equipped with a gel battery, which can only be charged at a constant current-limited voltage.
• To prevent damage to the battery and the electronics system, a
gel battery that is connected must under no circumstances be
charged with a quick charger.
[ i] Tips
The vehicle battery must not be charged with a standard small
charger that plugs into the cigarette lighter or outlet. •

& WARNING
• Using incorrect or unmatched tires and I or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always use tires , rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
& WARNING (continued)
• All four wheels must be fitted with radial tires of the same type,
size (rolling circumference ) and the same tread pattern. Driving
with different tires reduces vehicle handling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for e xample with winter tires - only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build-up , sudden tire failure ,
including a blowout and sudden deflation and loss of control .
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chnical reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked. Redu ced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision.
• Run flat tires may only be used on vehicles that were equipped
with them at the fa ctory . The vehicle must have a chassis designed
for run flat tires and a factory-installed tire pressure monitoring
system * that indicates a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer or t ire specialist to see if your vehicle can
be equipped with run flat tires .
If run flat tires are used, they must
be installed on all four wheels . Mixing tire types is not permitted. .,
