D Battery
This warning/indicator light detects a mal ­
function in the generator or in the vehicle's
electrical system.
The . warning/indicator light illuminates
when you switch on the ignition and must go
out after the engine has started.
• Alternator fault: Battery is not being
charged
If the indicator light turns on and the mes­
sage appears, there is a malfunction in the
generator or vehicle e lectrica l system.
Drive to you r authorized Audi dealer or quali­
fied workshop immediately. Because the vehi­
cle battery is discharging, turn off all unnec­
essary electrical equipment such as the radio .
Seek professional assistance if the battery
charge leve l is too low.
(•i Low battery charge : battery will be
charged while driving
If the indicator light turns on and the mes­
sage appears, there may be limited star ting

~ Engine oil pressure malfunction
The red engine oil pressure warning symbol
requires immediate service or repair . Driving
with a low-oil-pressure indication is likely to
inflict severe damage to the engine .
• Switch off engine and check oil level
If the indicator light turns on the message ap­
pears, the oil pressure is too low.
"" Pull off the road .
... Stop the vehicle.
... Tur n off the engine .
"" Check the engine oil level¢ page 225.
"" If the eng ine oil level is too low, add eng ine
oil ¢

"" If the engine oil level is correct and the indi ­
cator light still turns on, turn the engine off
and do not continue driving. Seek professio­
na l assistance .
(D Tips
-The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel ,
and always before going on a long trip.
- The yellow oil level warning indication
II requires oil refill or workshop serv­
ice without delay. Do not wait until the

(ESP)
This warning/indicator light monitors the
electronic stabilization program.
When you sw itch the ignition on, the indicator
light
G1 turns on briefly to check the function .
If thE:
G1 indicator lamp blinks while dr iving,
the ESP or ASR (Ant i- Slip Regulation) is active ­
ly regulating.
If thE:
hJ indicator lamp illuminates, the sys­
tem has switched the ESP off.
If the indicator light

vate the ESP by switching the ignition off and
then on again . The warning/indicator light

functiona l again.
Stability program and ABS fault! See own­
er's manual
If the indicator light D] and the ABS indicator
light

malfunct ion in the ABS system or electron ic
differential lock . This also interrupts the ESP.
The brakes still function with their normal
power, but ABS is not active.
Drive to your authorized Aud i dealer immedi ­
ately to have the malfunction corrected .
If the battery term inals were disconnected
and re-connected, the vehicle was jump start­
ed or the battery is very weak, the ESP sensor
