A WARNING
California Proposit ion 65 Warning:
- Battery posts, terminals and related acces­ sories contain lead and lead compounds, chemicals known to the State of California
to cause cancer and reproductive problems .
Wash hands after handling .
Q) Note
If the vehicle will be parked for long periods
of t ime, protect it against the cold so that it
w ill not be destroyed by "freezing"
~page 242 .
Vehicle battery
The term "vehicle battery " refers to the 12 Volt
battery in your vehicle .
Not running the vehicle for long p eriods of
t ime
If you do not drive your vehicle for several days or
weeks, electrical equipment is gradually scaled
back or switched off . This reduces energy use and
ensures the veh icle w il l be able to sta rt after long
pe riods of time
i:::> page 91. Some convenience
functions, such as interior light ing or power sea t
adjustment, may not be available under certain
circumstances . These convenience functions will
be avai lab le again once you switch the ignition on
and start the engine.
Even when electrical equipment is switched off ,
the equipment can still drain the vehicle battery if the vehicle is not driven for long periods of
time. Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery.
The vehicle battery must be charged every month to reduce the risk of this happen ing
i:::> page 242.
Contact an author ized Audi dealer or authorized
Aud i Serv ice Facility for more information.
Winter operati on
Cold weather places higher demands on the vehi­
cle battery . This results in reduced start ing abili ­
ty . Have the vehicle battery checked by an au­
thori zed Audi dealer or authorized Audi Service
Facility before the co ld time of year.

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 can­
not 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 233.
@ 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.
