Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicle for long periods of
time
If yo u do not dr ive you r vehicle for seve ral days or
weeks, e lectrical equipment is gradually sca led
back or switched off. This reduces ene rgy use and
ensu res the veh icle w ill be able to start after long
pe riods of time¢
page 147. Some convenience
functions, suc h as inter ior light ing or power seat
adjustment, may not be available under certa in
circumstances. These convenience funct ions w ill
be ava ilable again once you switc h the ign ition on
and start the engine.
Even when electrical equ ipment is switched off,
the equ ipment can still d rain the vehicle battery
if the vehicle is not drive n for long per iods of
time. Deep d rain ing results in a chemical reaction
that des troys the inside of the vehicle b attery.
The vehicle batte ry must be charged every mont h
to reduce the risk of this happening ¢
page 327.
Contact an author ized Audi dealer or authorized
Aud i Service Facility for more information.

Checking and Filling
& WARNING
- A highly explosive mixture of gases can form
when charging batter ies . Only charge the
vehicle battery in well-vent ilated areas .
- A drained vehicle battery can freeze at tem­
peratures a round 32 QF (0 QC) . A frozen or
thawed veh icle battery must not be charged
and must not be used anymore. If ice fo rms,
the battery housing ca n crack and ba tte ry
electrolyte can lea k out, which increases the
risk of an explosion and chemi cal bu rns.
Contact an authorized Au di dea le r o r au­
tho rized Audi Serv ice Facility fo r more info r­
mation.
- Do not connect o r disconnect the ch arging
cable while charg ing because this increases
t h e risk of an exp losion.
(D Tips
- Only charge the vehicle battery through the
con nections in the engine compartment .
- Read a ll of t he manufacture r's ins tructions
for the charger befo re charg ing the vehicle
battery.
Windshield washer system

To reduce the r isk of lime sca le deposits o n the
spray nozzles, use clean water with low amounts
of calcium . Always add window cleane r to the wa-
328
te r. When the outside tempe ratures are cold, an
anti-freezing agent shou ld be added to the water
so that it does not freeze.
(D Note
- The concentration o f anti -freezing agent
must be adjusted to the ve hicle operating
conditions in the respective cl imate. A con­
centration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­ tives to the washer fluid.
- Do not use a glass cleaner t hat contains
paint so lvents, because t his could damage
the paint.

::r ' 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
~ 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 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
handling of your vehicle's battery.
-Always shield your eyes and avoid leaning
over the battery whenever possible.
- A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- 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
c>page 319.
@ 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.

-When connecting jumper cables, make sure
that they cannot get ca ught in any mov ing
parts in the engine compartment.
- Do not bend over the batteries - danger of
chem ica l burns!
- The battery cell lock ing screws must be
t ightened sec ure ly.
- Be fore you check anything in the e ngine
compartment, a lways read and hee d all
WAR NINGS

- Always connect POSITI VE (+ ) to POS ITIV E
( + ), and NEGATIVE( -) to NEGAT IVE( -)
g roun d post of t he battery mana ger contro l
u nit.
- Check that a ll sc rew p lugs on t he battery
cells are screwed in firmly. I f not, t ighten
plugs prior to connecting clamp on negative
batte ry terminal.
- Please note that the procedure fo r con nect­
i ng a jumper cab le as desc ribed above ap­
p lies specifica lly to the case of yo ur vehicle
being jump starte d. When you are giv ing a
ju mp s ta rt to anothe r vehicle, do
not con­
n ect the neg ative (-) cab le to the neg ative
(-) t ermin al on the di sch arged b attery @

nega tive ( -) cab le to either a solid me tal
com ponent that is f irm ly bolted to the e n­
gine block o r to the engine bloc k itself. If
the battery that is be ing cha rge d does not
vent to the outs ide, escap ing battery gas
could ignite and exp lode!
