can be cracked due to ice format ion and can leak
battery acid.
Battery charging (Maximum charging rate of
30 amps/ 14.8 Volt)
When charging at
low voltages (e.g. with a trick­
le charger), the battery cables do not have to be
d isconnected first. The battery caps should
not
be opened when charging a battery.
It is not necessary to remove the battery from
the luggage compartment, and it is also not nec­
essary to disconnect the cables.
Fast charging the battery (charging rate
above 14.8 Volts)
F or technical reasons do not use a battery charg­
er that uses voltage greater than 14.8 Volts to
charge your vehicle's battery.
A WARNING
Charging a battery can be dangerous.
- 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 exp losive.
- To reduce the danger of explosion, never
connect or disconnect charger cables wh ile
the charger is operat ing.
- 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.
Checking and Filling
(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 hove the some specifica­
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
responsible for distribut ing the e lectrical energy
throughout your vehicle
c;, page 121 . The intelli ­
gent energy management system will keep the
engine battery charged better than vehicles with­
out this system. To make 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
t ime your vehicle was delivered). Specifications
are listed on the battery housing . Your author­
ized dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re­
plac ing the battery.
The new battery must have the same capacity,
voltage (12-volts), amperage, construction and plug seal ing.
When install ing the battery, make sure the ign i­
t ion and all electr ical consumers are switched
off .
(D Note
Make sure the venti lation hose on the s ide of
the battery is connected, otherwise fumes or battery acid can leak out .
@ For the sake of the environment
Because of the problem of proper d isposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfur ic acid and lead and must
always be disposed of properly in compliance .,.

CD Note
Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
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 in­
jury. Follow the instructions below for safe hand Ling of your vehicle's battery .
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A discharged battery can freeze at tempera­
tures just below 32 °F (0 °C). Before con­
necting a jumper cable, you must thaw the
244
frozen battery completely, 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 gases.
Keep sparks, flame and lighted cigarettes
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 battery. Use of
batteries of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion and personal injury .
- Never charge a frozen battery. Gas trapped in the ice may cause an explosion .
- Never charge or use a battery that has been
frozen . The battery case may have be weak­
ened .

Consumer inf orm ation
today's a utomo biles, have steadily re duced the
scope of maintenance and repairs whic h can be
carried out by veh icle owners.
Also , sa fet y and
en vironmental
concerns place very strict limits
on the nature of repairs and adjustmen ts to en­
g ine and transmission parts wh ich an owner can
perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, testing devices and other
equ ipment available to specially trained work ­
shop personnel in order to assure proper per­
forma nce, re liability and safety of the veh icle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliab ility of your
ve hicle and eve n void your vehicle warranty .
Therefo re, proof of se rvicing in a ccordance w ith
the m aintenance sched ule may be a condition for
up ho ld ing a possible wa rranty claim made within
the wa rranty pe riod.
Above all , ope rational safety can be adversely af­
fected, cre ating unne cessa ry risks fo r you and
your passengers.
I f in doubt about any servicing, have it done by
your author ized Audi dealer or any other properly
eq uipped and qualified workshop . We strongly
