0 Alternator/vehicle battery
• Electrical system: malfunction! Battery is
not being charged
There is a malfunction in the alternator or the ve­
hicle electrical system.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately. Because the ve-
14
hicle battery is discharging, turn off all unneces­
sary electrical equipment such as the radio. See
an authorized Audi dealer or authorized Audi
Service Facility if the battery charge level is too
low.
(•) low battery: Battery will be charged while
driving
The starting ability may be impaired.
If this message turns off after a little while, the
vehicle battery charged enough while driving.
If the message does not turn off, have an author­
ized Audi dealer or authorized Audi Service Facili­
ty repair the malfunction .
~ Engine stop while driving
• Engine stopped: No power steering and
brake support.
There is a malfunction in the engine or in the fuel
supply system.
More force is needed to steer and brake the mov­
ing vehicle when the engine is stopped . If the
ve·
hicle is rolling, try to bring it to a stop off to the
side from moving traffic. See an authorized Audi
dealer or authorized Audi Service Facility for as­
sistance.
A WARNING
If the engine stops while driving, you will
need to use more force to brake the vehicle.
This increases the risk of an accident. There
will still be power steering if the ignition is
switched on while the vehicle is rolling and
there is sufficient battery charge . Otherwise,
you must use greater force when steering.
~ Engine oil pressure
• Turn off engine and check oil level
Stop the engine and do not continue driving.
Check the engine oil
level¢ page 193.
-
- If the engine oil level is too low, add engine oil
¢ page 194 . Only continue driving once the in-
dicator light turns off.

" N .... 0 0 \.J ' h). To stop the engine, press and hold the
I START ENGINE STOPI button and also press the
brake pedal.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You may need to
use more force when braking or steering.
Because you cannot brake and steer as you
usually would, this could lead to accidents
and serious injuries.
- If you leave the vehicle, switch the ignition
off and take the vehicle key with you . Other­
wise, the engine could be started or electri­
cal equipment such as the power windows
could be operated. This can lead to serious
injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position .
Otherwise, there is the risk that the vehicle
could roll unintentionally.
0 Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off .
(D Tips
For up to 10 minutes after stopping the en ­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following
reasons:
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.

Checking and Filling
(D Note
If the vehicle will be parked for long periods
of t ime , protect it against the co ld so that it
will not be destroyed by "freezing"
c;,page 198 .
Vehicle battery
The term "vehicle battery " refers to the 12 Volt
bat tery in your vehicle.
Not running the vehicle for long pe riods of
t ime
If you do not drive your vehicle for several days o r
weeks , electri cal equipment is gr adually scaled
back or switched off . This reduces energy use and
ensures the veh icle w ill be able to start after long
periods of
time r:::;, page 123 . Some conve nience
functions, s uch as interior lighting or power seat
adj ustment, may not be available under certa in
circumstances. These convenience f unct ions w ill
be ava ilab le aga in once you switch the ignition on
and start the engine .
E ven w hen electrica l equ ipme nt is swi tched off,
the equipment can still d rain 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
t o reduce the risk of this happening
r:::;, page 198.
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
thor ized Audi dealer or authorized Audi Service
Facility before the co ld time of year .
