2011 AUDI R8 SPYDER battery capacity

Driving with your
quattro ®
With all-wheel drive, all four wheels are driv­
en .
General information
With all-wheel drive, power is distributed to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the time. See also
t::;> page 150.
Winter tires
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
all four
wheels.
Snow chains
Where snow chains are mandatory on certain
roads, th is normally also applies to vehicles
with all-wheel drive
Q page 204 , Snow
chains.
Replacing wheels/tires
Only the wheel/tire sizes specified by the
manufacturer may be used on vehicles with
all-wheel drive
<=> page 199.
A WARNING
-Always adjust your driving to road and
traffic conditions. Do not let the extra
safety afforded by all-wheel drive tempt
you into taking extra risks.
- Although a ll-wheel drive is very 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 beg in 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 time, the bat­
tery is discharged 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 ical ener­
gy. Starting ability is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is standing.
With the ign ition switched off, it controls the
energy supply to the various electrical compo­
nents. Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability. .,..

~ Install the battery cover.
~ Close the luggage compartment lid
¢page 42.
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 185 .
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 187
- 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 must have the same specifi­
cations as the old one.
Your vehicle is equipped with an intelligent
energy management system for distributing
electricity ¢
page 155. 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
thori zed dealer mus t code the battery in the
energy management control module .
T he 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 Oc ­
tober 2006) and VW 7 50 73 (from August 2001).
Since the vehicle battery is difficult to reach,
we recommend having the battery replaced by
an authorized Audi R8 dealer or other quali-
fied workshop . ..,. •

220 What do I do now?
connected to the battery of another vehicle,
using a pair of jumper cables to start the en­
gine.
Both batteries must be rated at 12 volts. The
capacity (Ah) of the booster battery must not
be substantially less than the capacity of the
discharged battery.
Jumper cables Use
only jumper cables of sufficiently large
cross section to safely carry the starter cur­
rent. Refer to the manufacturer's specifica­
tions.
Use only jumper cables which have
insulated
terminal clamps and are properly marked for
distinction :
plus(+) cable: in most cases colored red
minus(-) cable: in most cases colored black
A WARNING
Batteries contain electricity, acid, and gas .
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible.
- A discharged battery can already freeze
at temperatures just below 32 °F (0 °C).
Before connecting a jumper cable, the
frozen battery must be thawed com­
pletely, otherwise it could explode.
- Do not allow battery acid to contact eyes
or skin. Flush any contacted area with
water immediately.
- Improper use of a booster battery to
start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with
a low acid level in the battery.
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery. Use of batteries of different voltage or substantially different
"Ah" rating
may cause an explosion and personal 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 batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The capacity (Ah) of the booster battery should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine compartment, always read and heed all
WARNINGS
9 page 175, Working in the
engine comportment.
(!) Note
-Applying a higher voltage booster bat ­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected.
(D Tips
- The discharged battery must be properly
connected to the vehicle's electrical sys­
tem.
- Switch off any car phone, or follow the
car phone instructions for this situation.
