226 Check ing and filling
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnected from the vehicle elec
trica l system for safety reasons¢
& in Re
pair, core and disposal of the airbags on
page 158.
Disconn ect ing the battery terminal s
Some vehicle functions (power window regu
lators, for example) are lost if the battery ter
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicles not dri ven fo r lo ng p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo
nents are gradually cut back or switched off.
This reduces energy consumption and main
tains starting capabil ity over a longer period
¢ page 190.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be ava ilable again when you
turn on the ignition and start the eng ine.
Winter operati on
During the winter months, battery capacity
tends to decrease as temperatu res drop . This
is because more power is also consumed while
start ing , and the headlights, rea r window de
fogger, etc., are used more often .
Avoid unnecessary power consumption, par
ticularly in c ity traffic or when traveling on ly
short distances. Let you r authorized Audi
dea ler check the capacity of the vehicle bat
tery before winter sets in
¢ page 228. A well
charged batte ry w ill not only prevent sta rting
prob lems when the weather is cold, but wi ll
a lso last longer.
(D Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery sho uld be removed and
stored where it w ill not freeze . This will
prevent it from be ing damaged and having
to be replaced .
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. Before you check any
t hi ng in the luggage compartment,
read and
heed all WARNINGS

_& WARNING
Whenever working on the battery or on
the electrical system, there is the risk of
injury, accident and even fire . Read and
heed the following WARNINGS:
-
(D 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 .
Battery replacement
The new battery must have the same specifi
cations and dimensions as the original equip
ment battery .
Intelligent energy management in your vehi
cle is responsible for d istributing the electr i
cal energy throughout your vehicle
c::>
page 190 . The intelligent energy manage
ment system w ill keep the engine battery
charged bette r then vehicles w ithout t his sys
tem. To make sure the additional electr ica l en
ergy 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 time your vehicle was delivered). Specifi
cations are listed on the bat tery hous ing. Your
author ized Audi dealer must code the battery
in the energy management system to enable
you to use the energy management functions
correctly after replac ing the battery .
If it is not possible to use a battery of this
type, the new battery must have the same ca
pacity, voltage (12 volts) , amperage, con
struction and plug sea ling.
When insta lling the battery, make sure the ig
nition and all electr ical consumers are turned
off.
(D Note
Make sure the ventilation hose on the s ide
of the battery is connected , othe rwise
fumes or battery ac id can leak out .
@ For the sake of the environment
Because of the problem of proper d isposal
of a battery, we recommend your author
ized Aud i dealer change the battery for

262 Emergency situations
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
Q;) 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
gine .
Jumper cables
Use only jumper cables of sufficiently
large cross section to carry the starter current
safely. Refer to the manufacturer's specifica
ti ons.
Use only jumper cables with
insulated termi
nal 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. -
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 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¢
page 208, Engine com
partment.
@ 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. ..,.
