Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
W ith
high outside temperatures or long da ily
drives we recommend that you have the electro lyte level checked by an authorized Audi dea ler or
qua lified workshop. The e lectrolyte level should
a lso be checked each t ime the batte ry is charged
¢ page 22 7.
H ave the battery checked when you take your ve
hi cle in for serv ice. You a re well advised to re
p lace a batte ry that is o lde r than 5 years .
Check ing and Filling
Hybrid dr ive *: you can find important in format ion
about the high voltage battery under
¢ page 100.
Disconnecting the battery te rminals
Some vehi cle functions (power window regula
tors, for examp le) are lost if the batte ry te rm i
nals a re disconnected . These functions have to be
re learned after the battery terminals a re con
nected again. To prevent this, the battery should
only be disconnected from the vehicle electrical
system when absolutely necessary for repa irs.
Vehicles not dr iven for long p eriod s
If you do not drive your vehicle over a period of
severa l days or weeks, electrical compone nts are
gradually cut back or switched off. This reduces
energy consumpt ion and maintains starting ca
pability over a longer per iod
¢ page 192.
T ake into consideratio n that when you unlock
your vehicle, some convenience functions, suc h
as the inter ior lights or the power seat adjust
ment, may not be ava ilab le. The conve nience
funct ions will be available again when you turn
on the ignition and sta rt the eng ine.
Winter operation
D uring the winter months, battery capacity tends
to decrease as temperatures drop. This is be
cause more power is also consumed while start
i ng, and the headlights, rear w indow defogger,
etc., are used more ofte n.
Avo id unnecessary power consumption, pa rtic u
larly in city traff ic or when traveling only short
distances . Let your author ized Audi dealer check
the capacity of the veh icle batte ry before winter
sets in
¢ page 22 7. A we ll charged batte ry will
not only p reve nt start ing prob lems when the

Checking and Filling
-Always follow the operating instructions
provided by the battery charger manufactur
er when charging your battery.
- Never charge a frozen battery . It may ex
plode because of gas trapped in the ice. Al
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen .
The battery housing may have cracked and
weakened when the battery froze .
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark . Do not smoke. Hydrogen gas generat
ed by the battery is explosive .
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charging 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 washed off with a solution of
warm water and baking soda to neutralize
the acid.
(D Note
Never use a fast charger as a booster to start
the engine. This will seriously damage sensi
tive electronic components, such as control
units , relays , radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
~ page 192. The intelli
gent energy management system will keep the
engine battery charged better then vehicles with
out this system. To mak e sure the additional
electrical energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu facture only (the same as those installed at the
time your vehicle was delivered) . Specifications
228
are listed on the battery housing. Your author
ized dealer must cod e the battery in the energy
management system to enable you to use the en
ergy management functions correctly after re
placing the battery.
If it is not possible to use a battery of this type,
the new battery must have the same capacity,
voltage (12 volts), amperage, construction and plug sealing.
When installing the battery, make sure the igni
tion and all electrical consumers are turned off.
([) Note
- Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of bat
tery can cause problems in the vehicle elec
trical system. When replacing the vehicle battery, always install one with the same
specifications as the original battery.
@ For the sake of the environment
Because of the problem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat
teries contain sulfuric acid and lead and must
always be disposed of properly in compliance
with all environmental regulations. Disposing
of vehicle batteries improperly is
very danger
ous to the environment.

Low aspect ratio tires
Your Audi is factory -equipped with low aspect ra
tio tires. These t ires have been tho roughly tested
a nd been se lected specifically fo r yo ur model fo r
thei r supe rb per fo rman ce , road feel and handling
un der a va riety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re details .
T he low aspect ratio of these t ires is in dicated by
a nume ral of
55 or less in the tire's size desig na
tion . The numera l rep resents the rat io o f th e
tire's sidewall he ight in relat ion to its tread width
expressed in pe rcentage. Conventional tires have
a height/w idt h rat io o f 60 o r more .
The performance of low-aspect -ra tio tires i s par
ticularly sensitive to improper inflation pres
sure . It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at least once a month and always
before a long trip ¢
page 240.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, cu rbs, gullies or
246
ridges on the road, particularly if the tire is un
derinflated.
I n orde r to mi nimize the occur rence o f imp act
dam age to the tires o f yo ur vehicle, we recom
mend that you observe the following preca u
tions:
- Always m aintain reco mmende d in fla tion pres
sures. Check yo ur tir e pressure eve ry 2,0 00
m iles (3,00 0 km) and add air if necessary .
- Dr ive c arefully on ro ads w ith potholes, deep
gu llies o r ridges . The impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso ca use
damage to your t ires.
- After any impact, immediate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not always
easy to see . Damage can lead to loss of a ir and
unde rinflation, w hich could event ua lly cause
tire fa ilure . If you believe that a tire may have
be en damaged, replace the tire as soon as pos
sible .
- These tires may wear mo re quickly than o thers .
- Please also remember that, while these tires delive r responsive hand ling, they may ride less
comfortab ly and make mo re noise than o ther
choi ces.
