2012 AUDI R8 SPYDER battery capacity

Driving with your
quattro ®
With all-wheel drive, all four wheels are driv­
en .
Gene ral inform ation
W ith all-wheel dr ive, power is distributed to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the t ime . See also <::;>
page 142.
Winter t ires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all -sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
a ll f our
wheel s.
Snow chain s
Where snow chains are mandatory on certain
roads, th is normally also applies to vehicles
with all-wheel drive
Qpage 198, Snow
chains.
Replacing wheel s/tire s
Only the wheel/tire sizes specified by the
manufacturer may be used on vehicles with
all-wheel drive
<=> page 193 .
A WARNING
-Always adjust your driving to road and
traffic conditions. Do not let the extra
safety affo rded by a ll-wheel d rive tempt
you into taking extra risks .
- Although a ll-wheel drive is ve ry effect ive,
always remember that braking capacity
is limited by tire traction . You should
therefore not drive at excessive speeds
on icy or slippery road surfaces.
- On wet road surfaces, be careful not to drive too fast because the front wheels
cou ld begin to slide on top of the water
(aquaplaning). If this should occur, you
will have no warning from a sudden in­ crease in engine speed as with a front-

wheel drive vehicle. Always drive at
speeds which are su ited to the road con­
ditions. -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventional energy system
is not driven for a long per iod of t ime, the bat­
te ry is d ischarged by idling current consumers
(e .g. immobi lizer). In certain circumstances it
can resu lt in the re being insufficient energy
available to start the engine.
Intelligent energy management in your vehi­
cle handles the distribution of e lectr ica l ene r­
gy. Starting ability is markedly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
b atte ry diag nosis, idling current m an age­
m ent
and dy namic energ y manag ement .
Batte ry diagno sis
Battery diagnosis continuously determines
the state of the batte ry. Sensors determine
battery voltage, battery current and batte ry
temperature . This determines the current
state of charge and the power of the battery.
Idling current manag ement
Idling current management reduces energy
consumption while the vehicle is standing.
Wi th the ign ition switched off, it controls the
energy supply to the various electrica l compo ­
nents. Data from battery diagnosis is consid­
ered.
Depend ing on the ba ttery's state of charge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability. .,..

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 . ..,. •

182 Checking and filling
(D Note
- Your vehicle is equipped with a specia l
battery. Installing a different type of
battery can cause prob lems in the vehi­
cle electrical system. When replacing the
vehicle battery, always install one with
the same spec ificat ions as the original
battery .
- Make sure that the gas venting hose is
always connected to the o riginal open ing
on the battery side. Otherw ise gasses or
ba tte ry acid could leak out .
- Battery holder and term inals a lways
have to be secured cor rectly.
- Read and follow the warnings under
9 page 179, Working on the battery be­
fore performing any work on the batte ry.
@) For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author­
ized Audi dealer change the battery for
you . Batteries contain sulfur ic ac id and
lead and must always be disposed of prop­
erly in compliance with a ll environmenta l
reg ulations. D isposing of vehicle batteries
improperly is very dangerous to the envi­
ronment. Make sure that the removed bat­
tery ca nnot overbalance, otherwise sulfu­
r ic acid might escape!
