0 ::..:: co ..... ..... Disconnecting the battery terminals
Some vehicle func tion s (p ower w indow reg ula­
tors, for example) are lost i f th e battery termi ­
na ls are d isconnected. These functions have to be
relearned afte r the battery termina ls are con­
nected aga in. To prevent th is, the batte ry shou ld
only be disconnected from the vehicle e lectr ica l
system w hen abso lute ly necessary for repairs.
Vehicles not driven for long periods
If yo u do not drive you r vehicle over a period of
seve ral days or weeks, e lectrical components a re
g radually c ut back or sw itched off. This reduces
e nergy consumption and ma inta ins starting ca ­
pability over a longer pe riod

Some o f the conven ience f unctions may not ope r­
ate, s uch as the inte rior lights or the power seat
ad justment. The convenience functions will be
ava ila ble aga in whe n you tu rn o n the ignition and
start the engine .
Winter operation
During the winter months, battery capacity tends
to dec rease as temperatu res dr op. This is be­
cause more power is also consumed wh ile start ­
in g, and the head lights , rear wi ndow defogge r,
etc., are used more of ten .
Avoid un necessa ry power consumption, part icu­
l arly in city traffic or when t rave ling on ly short
d ista nces . Let your authorized Audi dealer check
the capaci ty of the vehicle battery be fore w inte r
sets in

Checking and Filling
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart ­
ment under the floor. Befo re you check anything
i n the luggage compart ment ,
read and heed all
WARNINGS
c> &_ .
Always heed the safety warnings , when working
o n the veh icle batte ry or t he ve hicle elec trical
system to prevent in jury .
The following WARNINGS are very important
when working on the battery :
Always heed the following WARNING SYM-
BOLS and safety precautions when wo rking on
the battery.
®
Always wear eye protection.
A
Battery acid contains sulfuric acid. Al-
ways wear gloves and eye protection.
@
No
- sparks
- flames
- smoking.
~
When a battery is charged , it produces
hydrogen gas which is explosive and
could cause personal injury.
®
Always keep the battery well out of reach
of children.
A WARNING
= -
Whenever working on t he battery or on the
e lectr ica l system, the re is the r isk of injury,
accide nt a nd eve n fire. Read and he ed the fol­
l ow ing W AR NIN GS:
- Always wear eye protection. Do not let bat­
tery acid or any l ead particles ge t on you r
skin o r clothing. Shield yo ur eyes. E xplosiv e
g ases can ca use b lindne ss or other in jury.
- Ba tte ry acid contai ns sulfur ic acid. Sulfu ric
acid can ca use blindness and s evere burns.
- Always wea r gloves and eye protection . Do
n ot tilt t he batte ry because aci d could lea k
out of the ventilation openings. ""

Checking and Filling
the energy m anag ement functions correctly after
replacing the battery.
I f it is not poss ible to use a battery of th is type,
the new battery must have the same capacity,
voltage (12 -volts), amperage, construction and
p lug sealing .
When insta lling the batte ry, make sure the igni­
tion and all elec trical consumers are turned off.
CD Note
Ma ke sure the ventilation hose on the side of
t he batte ry is connected, othe rw ise f umes or
bat tery acid can lea k out.
@ For the sake of the environment
Because of the prob lem of proper dispo sal of
a ba tte ry, we recommen d your author ized
Audi de aler change the battery fo r you . Bat­
teries contain su lf u ric acid and lea d and must
always be disposed of properly in compliance
w ith all environmental regu lations. D ispos ing
of vehicle batteries improperly is very danger­
ous to the env ironment.

Emergency situations
Emergency situations
General
This chapter is intended for trained emergency crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
CD Note
Vehicles with an automatic transmission
cannot 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 largecross
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
handling 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
250
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 .
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
~page 203.
CD Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive
electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected.
@ Tips
The discharged battery must be properly con-
nected to the vehicle's electrical system. .,..
