Battery charging (Maximum charging rate of 30
amps/14.8 Volt )
When charging at /ow voltages (e.g . w ith a trickle charger ), th e
battery cab les do not have to be disconnected first. The batte ry caps
should
not be opened when cha rging a ba ttery .
It is not necessary to remove the battery from the luggage compart­
me nt.
Fast charging the battery (charging rate above 14.8
Volts)
For technical reasons do not use a battery cha rger that uses voltage
grea te r t han 14 .8 Vol ts to ch arge yo ur vehicle's ba tte ry .
& WARNING
Charging a battery can be dangerou s.
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery .
• Never charge a frozen battery . It may explode be cause of g as
trapped in the ice . Allow a frozen battery to thaw out first.
• Do not reu se batteries which were frozen . The battery h ousing
may have cracked and weakened when the battery froze.
• Charge the battery in a well ventilated area. Keep away from
open flame o r elect rical spark. Do not smoke. Hydrogen gas gener ­
ated by the battery i s explosive.
• To reduce the danger of e xplosion , never connect or disconnect
c harger cable s 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 wa shed
off with a so lution of warm water and baking soda to neutralize
the acid.
0 Note
N ever use a fast cha rger as a booster to s tart the eng ine. This w ill seri­
ously damage sensitive e lectronic components , such as control units,
re lays, ra dio, etc., as well as t he ba ttery cha rger. •
Battery replacement
The new battery must have the same specifications and
dim ensions as the original equipment b atte ry.
Inte lligent e nergy ma nagement in yo ur vehicle is responsib le for
distr ibuting the elect rical energy throughout your vehicle
~ page 24 7. The intelligent energy management sys tem will keep
the eng ine battery charged better then vehicles without this system.
T o m ake s ure the addi tional e lectr ic al energy is available o nce aga in
after you have changed the battery, we recommend that you install
b atter ies of the same type and manuf actur e only ( the same as t hose
installed at the t ime you r vehi cle was delive red) . Specifications are
listed on t he batte ry ho using. Yo ur authorized A udi dealer m ust code
the batte ry in the energy management system to enable yo u to use
the energy managemen t fu nct ions co rrectly after rep lacing the
battery .
If it is not poss ible to use a battery of this type, the new battery must
have the same capa city, volt age (1 2 volts), amperage, const ru ct ion
and plug sealing .
W hen installing t he ba ttery, ma ke s ure t he ign it ion and all electrica l
cons umers are turned off .
0 Note
Make sure the vent ilatio n hose o n the side of t he battery is
connected, otherwise fumes or battery acid can lea k out.

Checking and filling IJl!II
--------------------------------------------=------- =------
<£> For the sake of the environment
Because of the problem of proper disposal of a battery, we recom­
mend your authorized Audi dealer change the battery for you.
Batte ries contain sulfuric acid and lead and must always be disposed
of properly in compliance with all environmental regulations.
Disposing of vehicle batter ies improperly is very dangerous to the
environment. •
Windshield/headlight washer
container
Fig. 226 Engine
co mp artmen t: Wind­
sh ield and headlight*
washer fluid container
The washer fluid container is marked with the symbol Q on
its cap.
- Before you check anything in the engine compartment,
always read and heed all WARNINGS => & in "Working
in the engine compartme nt" on
page 280 .
-Lift the filler cap tongue to add washer fluid. You can fill
the container to the top.
- Press the cap back onto the filler neck after filling the
container.
Vehicle OP-eration
You can find the reservoir capacity in the table in::::, page 342.
Clean water should be used when filling up. If possible, use soft water
to prevent scaling on the washer jets. Always add a glass cleaner solu­
tion (with frost protection in the winter).
0 Note
Do not mix engine coolant antifreeze or any other additives to fill up
the windshie ld washer reservoir .•

Emergency situations
General
This chapter is intended for trained emergency crew s and working
personnel who ha ve the necessar y tools and equipment to perform
the se operations . •
Starting by pushing or towing
(D Note
Vehicles with an automatic transmis sion cannot be started by
pushing or towing .•
Starting with jumper cables
If necess ary, the engine can be started by connecting it to
the battery of an other vehicle .
If the engine shou ld fai l to start because of a discharged or weak
battery, t he battery can be co nnecte d to the battery of
another
vehicle, using a pair of jumper cable s to start the engine .
Jumper cables
Use only jumper cables of suffic ient ly large cross section to carry the
sta rter cur ren t safely . Refe r to the manufacture r's specifications.
Use on ly j umper cab les with
insulated te rm ina l clamps w hich are
distinct ly marked :
plus(+) cable in most cases colo red red
minus (-) cable i n most cases colored black.
Safety first
& WARNING
Batterie s contain electricity, acid, and gas . Any of these can cause
very serious or fatal injury . Follow the inst ructions 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 temperatures just below
32 °F (0 °C). Before connecting a jumper cable, you must thaw the
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 e xplosion.
• Vehicle batteries generate e xplos ive gases. Keep spa rks, 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 h ave a 12 -Volt
rating. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery. Use of batter ies of
different voltage or sub stantially different "Ah " rating may cau se
an explosion and personal injury.
• Never charge a frozen battery . Ga s trapped in the ice may cause
an e xplosion.
• 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 ) rating may cause an explosion and injury . The
capacity (Ah ) of the booster battery should not be lower than that
of the discharged battery. _..

[ i ] Tips
Th e d ischarged ba ttery mus t be p roper ly connec ted to t he veh icle's
electrical system. When jump starting or charging the battery , never
conne ct the negative grou nd ca ble to the ba ttery negative post
because the battery manager system must be ab le to detect the
ba ttery's state of charge. A lways connec t the negat ive g round cable
to the negative ground post of t he battery manager cont rol un it .•

Emergency towing with
commercial tow truck
General hints
Your Audi requires special handling for towing.
The following information is to be used by commercial tow truck
operators who know how to operate their equipment safely.
• Never tow your Audi, towing will cause damage to the engine
and transmission.
• Never wrap the safety chains or winch cables around the brake
lines.
• To prevent unnecessary damage, your Audi must be transported
with a flat bed truck.
• To load the vehicle on to the flat bed, use the towing loop found
in the vehicle tools and attach to the front or rear anchorage
~ page 336 and ~ page 33 7.
& WARNING
A vehicle being towed is not safe for passengers. Never allow
anyone to ride in a vehicle being towed, for any reason. •
Front towing loop
Do not install the front towing loop until it is needed.
