Checking and Filling
-If you get batt ery acid in your eyes or on
your skin, immediately rinse with cold wa ­
ter for several minutes and get medical at­
tention .
- If you should ingest any battery acid, seek
medical attention immediately.
- Do not expose the battery to an open flame, electric sparks or an open light .
- Do not smoke.
- Do not interchange the positive and nega-
tive cables.
- When working on the battery, be sure not to short-circuit the terminals with tools or oth­
er metal objects. This would cause the bat ­
tery to heat up very quickly, which could lead to damage or explosion and personal
injury.
- When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the nega tive ground cable .
- Before performing any work on the electri­ cal system, switch off the engine and igni­
tion as well as any electrical equipment. The negative cable on the battery must be dis­
connected. If you are just going to replace a
light bulb, then it is enough to switch off
the lights.
- Before disconnecting the battery, sw itch off
the anti-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis­
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure
all electrical consumers are switched off.
Reconnect the positive cable first and then
the negative cable. Never interchange the
cabl es - this could start a fire!
- Never charge a frozen or a thawed-out bat­
tery . It could explode! If a battery has fro­
zen, then it must be replaced. A discharged
battery can freeze over at 32°F (0°C).
- Make sure the vent hose is always attached
to the opening on the side of the battery.
202
- Never use batteries which are damaged .
There is the danger of an explosion! Always
replace a damaged battery.
A WARNING
California Proposition 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 .
(D Note
- Do not disconnect the vehicle battery when
the ignition is switched on or when the en­
gine is running, otherwise, you will damage
electronic components in the electrical sys­
tem .
-If your vehicle is going to stand for a long
period of time without being driven, protect
the battery from "freezing" , otherwise it
will be damaged and will then have to be re­
placed.
Battery charging
Starting the engine requires a well charged bat­ tery .

A discharged battery can freeze at temperatures
of only 32 °F (0 °C) . Allow a frozen battery to
thaw completely before attempt ing to charge it
~ & . However, we recommend not using a
thawed batte ry again because the battery casing
can be cracked due to ice formation 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
disconnected first. The battery caps should
not
be opened when charging a battery.
It is not necessary to remove the battery from
the luggage compartme nt.
Fast charging the battery (charging rate
above 14.8 Volts)
Fo r techn ical reasons do not use a battery charg­
e r that uses voltage greate r 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 .
Checking and Filling
-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 explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charg ing 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 w ith a solution of
warm water and baking soda to neutralize
the acid .
@ 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
cha rge r.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
r esponsib le for distr ibut ing the electrical energy
throughout your vehicle ~
page 175. The intelli­
gent energy management system will keep the
engine battery charged better then 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 Audi dealer must code the battery in the en-
ergy managemen t system to enable you to use

Emergency assistance
Using the spare tire (compact spare tire)
The compact spare tire is only intended for emer­
genc ies until you can reach a repair shop. Repla ce
it as qu ickly as possible with a standard wheel
and tir e.
There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for yo ur type of vehi­
cle. It must not be swapped with a compact
spare tire from another type of vehicle.
Snow chains
F or technica l reasons, the use of snow chains on
the compact spare tire is
not permitted .
If you do have to dr ive with snow cha ins and a
front tire fails, mo unt the spare wheel with t ire
instead of a rear tire. Install the snow chains on
the rear tire and use it to rep lace the defective
front tire .
A WARNING
-Never use the spare tire if it is damaged or if
it is worn down to the tread wear indicators.
-If the spare tire is more than 6 years o ld,
use it only in an emergency and with ex­
treme caution and carefu l dr iving .
- The spare tire is intended on ly for tempora­
ry and short-term use. It shou ld be replaced
as soon as possible with the normal wheel
and t ire.
- After mounting the compact spare t ire, the
t ir e pressure must be checked as soon as
poss ible. The tire pressure of the compact
spare tire must be 4.2 bar; otherwise, you
risk having an accident .
- Do not drive faster than SO mph (80 km/h).
You risk hav ing an accident.
- Avoid full-throttle accelerat ion, heavy brak­
ing, and fast cornering. You risk having an
acc ident.
- Never drive using more than one spare
wheel and tire. You risk having an accident .
- Normal summer or winter tires must not be
mounted on the compact spare wheel rim .
- For technical reasons, the use of tire chains
on the spare tire is not perm itted . If it is
226
necessary to drive with tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear tire. The newly
ava ilable front wheel must then be installed
in place of the rear wheel w ith the flat tire.
Installing the tire chain before mounting
the wheel and tire is recommended.
- Loose items in the passenger compartment
can cause serious personal injury during
ha rd braking or in an accident. Never store
the spare tire or jack and tools in the pas­
senger compartment.
Replacing wheels

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
236
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 191.
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. .,..

Emergency situations
-The battery cell locking screws must be
tightened securely .
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS

(D Note
Improper hook-up of jumper cables can ruin
the generator.
- A lways connect POSITIVE(+) to POSITIVE
(+), and NEGATIVE(-) to NEGATIVE(-)
ground post of the battery manager control
unit.
- Check that a ll screw plugs on the battery
cells are screwed in firmly. If not, tighten
plugs prior to connecting clamp on negative
battery terminal.
- Please note that the procedure for connect­
ing a jumper cable as described above ap­
plies specif ically to the case of your vehicle
being jump started . When you are giv ing a
jump start to another vehicle, do
not con­
nect the negative(-) cable to the negative
(-) terminal on the discharged battery @
c> fig. 186. Instead, securely connect the
negative (-) cab le to either a solid metal
component that is firm ly bolted to the en ­
gine block or to the engine block itself. If
the battery that is being charged does not
vent to the outside , escap ing battery gas
could ignite and explode!
