Instruments and warning/indicator lights
&, WARNING (continued )
extreme caution when working under the hood => page 299,
''Engine compartment "
[ i] Tips
Many functions are monitored by the Auto -Check system
=> page 28 . Ma lfunctions or faults wil l be identified either with a red
symbo l (pr iority 1
-Danger!) or with a yel low symbol (priority 2 -
Warning) .•
Electronic power control EPC
This warning/indicator light monitors the electronic
power control.
The EPC warning/indicator light (Electronic Power Control) i llumi ­
nates when you turn on the ignition as a function chec k.
[ i ] Tips
If this warning/indicator l ight i lluminates whi le you are driving, then
there is a malfunction in the engine electronics . Have the malfunc­
t ion corrected as soon as possible by your authorized Audi dea ler or
qualified repair facility .•
Generator D
This warning/indicator light detects a malfunction in the
generator or in the vehicle's electrical system.
The D warning/indicator light illuminates when you switch on the
igni tion and must go out a fter the engine has started.
If the
D warning/indicator light illuminates while you are driving,
you shou ld contact your authorized Audi dealer. Since the vehic le battery is discharging, you should switch off any unnecessary elec
­
t rical consumers (for example, the air conditioner).
0 Note
If the _f_ warning/indicator light (ma lfunction in the engine coo ling
system) in the instrument cluster shou ld
illuminate=> page 31, stop
the vehicle and turn off the engine . The water pump is not working
-this can cause engine damage. •
Electronic stabilization program (ESP) f1.
This warning/indicator light monitors the electronic stabi ­
lization program.
Th e warning/indicator light has the following functions:
• I t blinks while you are driving when the ESP is working .
• It illuminates when you switch on the ignition for approximate ly
2 seconds as a function check.
• It illuminates when there is a malfunction in the ESP. The
message
ESP fault! See owner's manual also appears in the instru­
ment cluster display and a warning tone sounds .
• It illuminates continuously when the ESP is switched off.
• It illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS sys tem.
If the battery terminals were disconnected and re-connected , the
vehic le was jump sta rted or the battery is very weak, the ESP sensor
system goes through a learning process for the first few yards. The
warning/indicator light illuminates. The warning/indicator light
goes out as soon as the learning process is complete.
If the ESP warning/indicator light illuminates and stays on after you
have started the engine, this may mean that the control system has
temporarily switched off the ESP . If this is case, you can reactivate
th e ESP by turning the ignition off and then on again . The

Battery charging
Starting the engine requires a well charged battery.
Always read and heed all WARNINGS below ~ & and~ &
in "Working on the battery" on page 319.
-Turn off the ignition and all electrical consumers.
- Make sure the area is well ventilated when you charge
the battery.
- Attach the red (positive
8) clamp of the charging equip­
ment to the positive terminal of the battery and the black
(negative(:)) clamp to the jumper terminal.
- Only now plug the mains lead for the charging equip­
ment into the wall outlet and turn it
on~ &.
-Make sure the charging rate is not over 30 amps/14.8
Volt.
-When the battery is fully charged: Turn the charging
equipment off and remove the mains lead from the wall
outlet.
- Now remove the clamps for the charging equipm ent.
A discharged battery can freeze at temperatures of only O °C . Allow
a frozen battery to thaw completely before attempting to charge it
=> ,&. . However, we recommend not using a thawed battery again
because the battery casing can be cracked due to ice formation and
can leak battery acid.
Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
When charging at low voltages (e.g . with a trickle charger ), the
battery cab les do not have to be disconnected first. The battery caps
should
not be opened when charging a battery. ~

reverse order.
The battery is vented to the outside to prevent gases from entering
the vehicle interior . Make sure that the jumper clamps are well
connected with their metal ports in full contact with the battery
terminals.
& WARNING
To avoid serious personal injury and damage to the vehicle, heed all warnings and instructions of the jumper cable manufacturer. If
in doubt, call 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 compartment.
• Before you check anything in the engine compartment, always
read and heed all
WARNINGS ~ page 299, "Engine compartment".
0 Note
Improper hook -up of jumper cables can ruin the generator. •
Always connect POSITIVE(+) to POSITIVE(+), and NEGATIVE(-) to
NEGATIVE( -) ground post of the battery manager control unit.
• Check that all screw plugs on the battery cells are screwed in
firmly. If not, tighten plugs prior to connecting clamp on negative
battery terminal.
• Please note that the procedure for connecting 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
vehicle, do not connect the negative(-) cable to the negative(-)
terminal on the discharged
battery @~ page 365, fig. 297. Instead,
securely connect the negative(-) cable to either a solid metal
component that is firmly bolted to the engine block or to the engine
block itself. If the battery that is being charged does not vent to the
outside, escaping battery gas could ignite and explode! •
