226 Check ing and filling
Never use a fa st charger as a booster to
start the engine . T his will seriously dam­
age sensitive electronic components, such
as control units, relays, rad io, etc ., as well
as the battery charger.
Battery replacement
The new bat tery must have the same specifi­
cations and dimensions as the original equip­
ment battery .
Intelligent energy man agement in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughout your vehicle
c::>
page 185. The intell igent energy ma nage­
ment system w ill keep the engine battery
cha rged bette r then vehicles w it h out th is sys ­
tem. To make sure t he addi tional e lectrica l en­
e rgy is availab le once again after you have
cha nged t he battery, we recommend that you
install batteries of the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. Your
author ized Audi dealer must code the battery
in the ene rgy management system to enable
you to use the ene rgy management functions
cor rectly after repla cing t he battery .
If it is not possible to use a battery of this
type, the new battery must have the same ca­
pac ity, voltage ( 12-volts), ampe rage, con­
s truction and plug sea ling .
When insta lling the battery , make sure the ig ­
ni tion and all electr ical cons umers are turned
off.
0 Note
Ma ke sure t he vent ilation hose on the s ide
of the batte ry is con nected, ot herwis e
fumes or battery ac id can leak out.
@ For the sake of the environment
Because of the problem of proper d isposa l
of a battery , we recommend your au thor­
i z ed Audi deale r change the batte ry for you
. Batteries contain sul fur ic acid and
l ead and must a lways be disposed of prop­
erly in comp liance with a ll environmental
regulations. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi­
ro nment .

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing .
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
g ine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to carry the starter current
safe ly. Refer to the manufacturer's specifica­
tions.
Use only jumper cables with
insulated termi­
na l clamps which are distinctly marked:
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.
Emergency situations 259
-A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise 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 batter ies generate explosive gas­
es. Keep sparks, flame and lighted c iga­
rettes away from batteries.
- Do not try to jump start any veh icle w ith
a low ac id 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 diff erent voltage
or substantially different "Ah" rat ing
may cause an exp losion 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 batter ies of different voltage or
substantially different capacity (Ah) rat ­
ing may cause an exp losion and injury .
The ca pa city (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¢
page 205, Engine com­
partment.
(D Note
- App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sit ive electronic components, such as
control units, relays, rad io, etc .
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
posit ive(+) terminals are connected. ..,. •
