230 Checking and Filling
-Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen 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 negative ground ca ble.
- Before performing any work on the elec
trical system, switch off the engine and ignition as well as any electrical equip
ment . The negative cable on the battery
must be disconnected . If you are just go
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable .
- Before reconnecting the battery, make
sure all electrical consumers are switch
ed off. Reconnect the positive cable first
and then the negative cable. Never inter
change the cables -this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could explode! If a battery has
frozen, then it must be replaced. A dead battery can free ze over at 32°F (O°C).
- Make sure the vent hose is always attach
ed to the opening on the side of the bat
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al
ways replace a damaged battery . A WARNING
-California Proposition 65 Warning:
- Battery posts, terminals and related ac
cessories contain lead and lead com
pounds, chemicals known to the State of
California to cause cancer and reproduc
tive problems . Wash hands after han
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is on or when the en
gine is running, otherwise, you will dam
age electronic components in the electri
cal 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.
Battery charging
Starting the engine requires a well charged
battery.

TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not operating properly . The
TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys
tem detects a malfunct ion, the telltale will
flash for approximately one minute and then
remain cont inuous ly illuminated. This se
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is illuminat
ed, the system may not be able to detect or
sig nal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea
sons, including the installa tio n of replace
ment or a lternate tires or whee ls on the veh i
cle that prevent the TPMS from funct ion ing
properly. Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re
placement or alternate tires and wheels allow
the
TPMS to continue to function properly.

29 0 Con sum er Inf ormation
comp lexity of today's automobi les, have
steadi ly reduced the scope of maintenance
and repairs which can be carried out by vehicle
owners.
Also, s afety an d e nvir onm ent al con
cerns place very strict limits on the nature of
repairs and adjustments to engine and trans
miss ion pa rts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing devices and oth
er equipment avai lab le to specially trained
workshop personnel in order to assure proper
performance, reliab ility and safety of the vehi
cle and its many systems .
Improper ma intenance, adjustments and re
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war ranty. Therefo re , proof of servic ing in accord
ance w it h the ma intenance sched ule may be a
condition for upholding a poss ible warranty
claim made within the warran ty period.
Above all, operational safety can be adve rsely
affected, creating unnecessary risks for you
and your passengers.
If in doubt about any serv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop .
We strong ly urge you to give your authorized
Audi dealer the opportunity to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, or iginal parts
and tra ined spec ialists to keep your vehicle
running properly .
