Charging a battery can be dangerou s.
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery .
• Never charge a frozen battery . It may explode be cause of g as
trapped in the ice . Allow a frozen battery to thaw out first.
• Do not reu se batteries which were frozen . The battery h ousing
may have cracked and weakened when the battery froze.
• Charge the battery in a well ventilated area. Keep away from
open flame o r elect rical spark. Do not smoke. Hydrogen gas gener ­
ated by the battery i s explosive.
• To reduce the danger of e xplosion , never connect or disconnect
c harger cable s while the charger is operating.
• Fast charg ing a battery is dangerous and should only be
attempted by a competent technician with the proper equipment .
• Battery acid that may spill during charging should be wa shed
off with a so lution of warm water and baking soda to neutralize
the acid.
0 Note
N ever use a fast cha rger as a booster to s tart the eng ine. This w ill seri­
ously damage sensitive e lectronic components , such as control units,
re lays, ra dio, etc., as well as t he ba ttery cha rger. •
Battery replacement
The new battery must have the s ame specifications and
dim ensions as the original equipment b atte ry.
Inte lligent e nergy ma nagement in yo ur vehicle is responsib le for
distr ibuting the elect rical energy throughout your vehicle
~ page 258. T he intelligent energy management sys tem will keep
the eng ine battery charged better than vehicles without this system .
T o m ake s ure the addi tional e lectr ic al energy is available o nce aga in
after you have changed the battery, we recommend that you install
b atter ies of the same type and manuf actur e only ( the same as t hose
installed at the t ime you r vehi cle was delive red) . Specifications are
liste d on the ba ttery ho using. Your a uthorized Audi dealer w ill then
code the battery management control unit.
Th e new batte ry must have the same capacity, volta ge (12 vo lts),
ampe rage, const ruct io n and p lug sealing .

Tires and wheels Ill
----------------
If you install rims, which do not have the sensors, or have sensors
w hich are not compa tible, then the tire pressure moni toring sys tem *
w ill not wo rk p roperly. I n this case, t he tire pressure monitor ing
system * wo uld not be ab le to monitor the tire pressure or warn yo u if
it is necessary .
• The battery inside of the tire pressure sensor has a limited service
l ife.
• Always dr ive wit h the
valve stem caps securely mo unted. We
recommend using factory ins ta lled
valve stem caps. As k your autho ­
r ized Audi dea ler to rep lace lost
valve stem caps .
Th e insta llation of repl acement tir es w ith s teel co rd bo dy plies in the
t ire sidewa ll may ca use ma lfunctio n of the tire pressure mo nitoring
system *, and is not recommende d (cord material informat io n i n
molded on the ti re s idewall).
Always check your tire pressure monito ring system* indicator afte r
re plac ing one or mo re tires on your vehicle. If the tire press ure m oni­
to ring system* indicator flashes, or is on, your system is not working
pro perl y. Yo ur repla ceme nt tire might be incomp atible with your t ire
pressure monitoring system*, or some component of the tire pres­
sure mon itor ing system * may be damaged.
& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to loss of cont rol, collision
and seriou s per sonal injury .
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original fa ctory-in stalled tires or other combination s that
have been specifically appro ved 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 u sed in an emergen cy and then with special care and at
lowe r speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged

tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type, size (rolling circumference ) and the same tr ead pattern.
Driving with different t ires reduces vehicle handling and can lead
to a lo ss of control.
• If the spare ti re is not the same as the tires that are mounted
on the vehicle - for example with w inter tires - only use the spare
tire fo r a sho rt pe riod of t ime and drive with extra care. Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s 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 technical reasons it is not always possible to use wheels
from other vehicles - in some c ases not even wheel s 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. Reduced airflow to
the brakes can them to overheat , increasing stopping distance s
and causing a collision.
• Run flat tires may only be u sed on vehicles th at were equipped
with them at the factory. The vehicle must have a chassis designed
fo r run flat tires and a factor y-in stalled tire pres sure monitoring
system* that indicates a loss of tire pre ssure. Incorrect use of run
flat tires can lead to vehicle damage or accident s. Check with an
authorized Audi dealer or tire 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 . ..,_
