(D Note
-Do not disconnect the vehicle battery
when the ignition is switched on or when
the engine is running, otherwise, you will
damage electronic components in the
electrical system .
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth
erwise it will be damaged and will then have to be replaced.
Charging the battery
Connections for charging the battery are lo
cated in the Luggage compartment.

When charging at low voltages (e.g. with a
trickle charger), the battery cables do not
have to be disconnected first. Before charging
at
high voltages, i.e . "fast charging", you
must disconnect both cables. In either case,
follow the instructions from the manufacturer
of the charger.
Fastcharging a battery is
dangerous c::.> .&. in
Working on the battery on page 186 .
It re
quires special charging equipment and the
knowledge to go with it. We recommend hav
ing your battery fast charged only by a quali
fied workshop .
A discharged battery can
freeze at tempera
tures of only 32 °F (0 °C). Allow a frozen bat
tery to thaw completely before attempting to
charge it
c::.> & . However, we recommend not
using a thawed battery again because the bat
tery casing can be cracked due to ice forma
tion and can leak battery acid .
Do not open the battery caps when charging
the battery.
WARNING
Charging a battery can be dangerous.
- Never charge a frozen battery. It may ex
plode because of gas trapped in the ice .
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro-
zen. The battery housing may have
-Che ck the tire p re ss ure on the spare imme
diatel y afte r mounting.
- Hav e the wheel b olt tightening torque
checked with a torque wrench a s soon a s
possib le by you r auth orized Audi dealer or
a qu alified ser vice sta tio n.
- With steel and allo y w heel rim s, the wheel
bolts are correctl y tight ened at a to rq ue of
90 ft lb (1 20 Nm ).
- If yo u notice while changin g a ti re th at the
wheel bolts are co rrod ed and diff icult to
turn , then they should be repl aced before
y ou check the t ighten ing to rqu e.
- Replace the flat t ire with a new one and
ha ve it installed on your vehicle as soon as
possib le . R emount th e wh eel co ver .
Until then, driv e with extra care and at re
d uced speeds.
A WARNING
- If you are going to equip your vehicle
with t ires or rims wh ich differ from those
w hich were factory installed, then be
sure to read the informat ion
~page 199,
New tires and replacing tires and
wheels.
- Always store the tools securely in lug
gage compa rtment. Otherw ise, in an ac

the vehicle .
(D Note
Do not use commerc ia lly available t ire
sealants. Othe rwise, the elec trical compo

Jump-starting
General
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,
us ing a
pair of jump er cabl es to start the en
gine.
Both batteries must be rated at 12 volts . The
capacity (Ah) of the booster battery must not
be substantia lly less than the capac ity of the
discharged battery .
Jumper cables
Use only jumper cables of suff ic ient ly large
cro ss se ction to safely car ry the starter cur
rent . Refer to the manufacturer's specifica
tions .
Use only jumper cab les which have
insulated
term inal clamps and are properly marked for
dist inction:
plu s(+) cable : in most cases colored r ed
m inu s(-) cable :
in most cases colored black
A WARNING ~
Batteries contain e lectric ity, acid, and gas .
Any of these can cause very serious or fata l
injury. Follow the instructions below for
safe handling of your vehicle's battery.
-Always shield your eyes and avo id lean-
ing over the battery whenever poss ible.
- A discharged battery can a lready freeze
at temperatures just below 32 °F (0 °(). Before connect ing a jumper cable , the
frozen battery must be thawed com
pletely, othe rwise it could explode .
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
wate r immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion. •

218 Wh at do I do now ?
-Vehicle batteries generate explos ive 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 substant ially different "Ah" rating
may cause an explos ion 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
substant ially different capacity (Ah) rat
ing may cause an explosion and injury.
T he capacity (Ah) of the booster battery
should not be lower than that of the dis
charged battery.
- Before yo u check anything in the engine
compartment, always read and heed all
WARNINGS ¢
page 172, Working in the
engine compartment.
(D Note
- Applying a higher vo ltage booster bat
tery wi ll ca use expensive damage to sen
sitive electronic components, s uch as
control units, relays, radio, etc.
- There m ust be no e lectrica l contact be
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected .
(0 Tips
-The discharged battery must be proper ly
connected to the vehicle's electrical sys
tem.
- Switch off any car phone, or follow the
car phone instructions for this situation.

4. Secure the other end to the jump start pin
© for the discharged battery@.
Starting the engine
.,. Start the eng ine of the vehicle providing as
s istance and allow it to run at id le.
.,. Now start the engine of the vehicle with the
discharged battery .
.,. If the engine does not start: Stop trying af
ter 10 seconds and then try again after
about 30 seconds .
.,. Disconnect the cable while the engine is
running in exactly
reverse order to that de
scribed.
The battery is vented to the outside to prevent
gases from entering the vehicle interior. Make
sure that the jumper clamps are well connect
ed with their
metal ports in full contact with
the battery termina ls.
A WARNING
To avoid serious personal i njury and dam
age to the vehicle, heed all warnings and
instructions of the jumper cable manufac
turer.
If in doubt, ca ll for road service .
- Jumper cables must be long enough so
that the vehicles do not touch.
- When connecting jumper cables, make
sure that they cannot get caught in any
moving parts in the engine compart
ment.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c:> page 172, Working in the
engine comportment.
Improper hook-up of jumper cables can ru
in the generator.
- Always connect POSITIVE( +) to POSI
TIVE(+), and NEGATIVE(-) to NEGATIVE
( - ) ground post of the battery manager
control unit.
- Check that all screw plugs on the battery
ce lls are screwed in firmly. If not, tighten
plugs prior to connecting clamp on nega
tive battery terminal.

What do I do now? 219
- Please note that the procedure for con
necting a jumper cable as described
above applies specifically to the case of
your vehicle being jump started. When
you are giving a jump start to another ve
hicle, do
not connect the negative(-) ca
ble to the negative(-) terminal on the
discharged battery@. Instead, securely
connect the negative(-) cable to eithe r a
solid metal component that is firmly
bolted to the engine block or to the en
gine block itself. If the battery that is be
ing charged does not vent to the outside,
escaping battery gas could ignite and ex
plode!
Emergency towing
with commercial tow
truck
' General hints
Your Audi requires special handling for tow
ing.
The following information is to be used by commercial tow truck operators who know
how to operate their equipment safely.
