¢page 37.
When charging at low voltages (e.g . with a
trickle charger ), the battery cables do not
have to be disconnected first. Before charging
at
high voltages, i.e. "fast charging", you
must disconnect both cables. In either case,
follow the instructions from the manufacturer
of the charger .
Fastcharging a battery is
dangerous ¢ & in
Working on the battery on page 179 .
It re­
quires special charging equipment and the knowledge to go with it. We recommend hav ­
ing your battery fast charged only by a quali­
fied workshop.
A discharged battery can
freeze at tempera­
tures of only 32 °F (0 °C) . Allow a frozen bat ­
tery to thaw completely before attempting to
charge it¢ & . However, we recommend not
using a thawed battery again because the bat­
tery casing can be cracked due to ice forma ­
tion and can leak battery acid .
Do not open the battery caps when charging
the battery.
_& WARNING
-
Charging a battery can be dangerous.
- Never charge a frozen battery .
It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro­
zen. 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 elec­
trical spark. Do not smoke. Hydrogen gas
generated 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 compe­
tent technician with the proper equip­ ment.
Checking and filling 181
- Battery acid that may spill during charg­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the acid .
@ Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc ., as well
as the battery charger .
(D Tips
-The vehicle battery must not be charged
with a standard small charger that plugs
into the cigarette lighter or outlet .
- Only charge the battery through the con­
nections in the luggage compartment.
Replacing the battery
The new battery mus t have the same specifi­
cations as the old one.
Your vehicle is equipped with an intelligent
energy management system for distributing
electricity¢
page 147 . The battery charges
better in vehicles with the energy manage ­
ment system than in vehicles without the sys­
tem . To ensure that the additional power is
available after replacing the battery , replacing
with the same type of battery from the same manufacturer (like the battery that was deliv­
ered with the vehicle) is recommended. An au­
thorized dealer must code the battery in the
energy management control module.
The new battery must have the same capacity,
voltage (12 volts), current and design and it
must be sealed with plugs. The battery must
conform to the standards TL 825 06 (from
April 2008) and VW 7 SO 73 (from April 2010).
Since the vehicle battery is difficu lt to reach,
we recommend having the battery replaced by
an authori zed Audi RB dealer or other quali-
fied workshop . ..,. •

210 What do I do now?
connected to the battery of another veh icle,
using a pair of jump er cable s to start the en­
g ine.
Both batter ies must be rated at 12 vo lts. The
ca pacity (Ah) of the booster battery must not
be substantially less than the capacity of the
d ischarged battery .
J umper cables
Use
only jumper cables of sufficiently large
cr oss sec tion to safely carry the starter cur­
rent . Re fer to the manu facturer's specifica ­
tions .
Use only jumper cables which have
insulated
termina l clamps and are properly marked for
distinction :
plu s(+) ca ble: in most cases co lored red
minu s(-) ca ble: in most cases colored black
A WARNING
Batteries contain electricity, ac id, and gas .
Any of these can cause ve ry serious or fatal
injury. Follow the instructions below fo r
safe handl ing of your veh icle's battery.
- Always shield you r eyes and avoid lean­
ing over the batte ry whenever possible.
- A discharged battery can already freeze
a t temperatures just be low 32 ° F (0 °C).
Before connecting a jumper cable, the
frozen battery must be thawed com­
pletely, otherwise it could exp lode .
- Do not a llow battery ac id to contact eyes
or s kin. Fl ush any contacted area w ith
water immediately .
- Improper use o f a booster battery to
start a ve hicle may cause an explosion.
- Vehicle batteries gene rate explos ive gas ­
es . Keep sparks, flame and lighted ciga ­
rettes away from batteries .
- Do not try to jump s tar t any veh icle with
a low acid level in the battery.
- Th e volt age of the booster battery must
also have a 12-Volt rating . The capacity
(Ah) of the booster battery shou ld not be
lower than that of the discharged bat­
tery. Use of batter ies of different voltage or substantially d
iffe rent "Ah" rating
may cause an exp losion and persona l in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen . The battery case may have
be weakened .
- Use of batter ies of different voltage or
substantially d ifferent capacity (Ah) rat­
ing may cause an exp losion and injury.
The capac ity (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine compa rtment, always read and heed a ll
WARNINGS
,=;, page 169, Working in the
engine comportment.
(!) Note
- App lying a higher voltage booster bat ­
tery will cause expens ive damage to sen­
sitive e lectronic components, such as
cont ro l uni ts, relays, rad io, etc.
- There must be no electrical contact be­
tween the vehicles as otherwise cur rent
c o ul d already start to f low as soon as the
positive( +) terminals are connected.
(D Tips
- T he d ischa rged ba ttery m ust be properly
c onnected to the veh icle's e lectr ica l sys ­
t em.
- Switch off any car phone, o r follow the
car phone instructions for th is si tuat ion.
