Inst rum ents and warnin g/indi cato r li ghts
If one of the turn signal light bulbs burn out, the turn signal will
flash twice as fast as normal. •
Electronic Stabilization Program (ESP)
The warning/indicator light monitors the electronic stabi­
lization program.
The warning/indicator light has the following functions :
• it flashes while you are driving , when the ESP is working .
• it illuminates when you switch on the ignition for approximately
2 seconds as a function check .
• it illuminates when there is a ma lfunction in the ESP.
• it illuminates after the battery has been disconnected.
• it illuminates continuous ly when the ESP is switched off.
• it illuminates if there is a malfunction in the ABS, since the ESP
is part of the ABS system.
If the ESP warning/indicator light i lluminates and stays on after you
have started the engine , this may mean that the control system has
temporari ly switched off the ESP. If this is case, you can reactivate
the ESP by switching the ignition o ff and then on again. The
warning/indicator light should go out to show that the system is
fully functional again.
If the battery terminals were disconnected and re-connected, the
vehic le was jump started or the battery is very weak, the ESP sensor
system goes through a learning process for the first few yards.
During this time, the indicator light illuminates. It goes out as soon
as the learning process is comp lete .
For more information about the ESP~
page 22. •
Generator 0
T his 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
ign itio n and must go out after 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 vehicle
battery is discharging, you should switch off any unnecessary elec ­
trical consumers (for example, the air conditioner) .
0 Note
If the -t 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 coo lant pump is not working
- this can cause engine damage! •
High beam ~D
The@:Dwarning/indicator light illuminates when the high beams are
on or when you use the headlight flasher. For more information
about using the high beams, see~
page 83. •
Electronic power control p
This warning/indi cator light monitors the electronic
power control.
The warning/indicator light (Electronic Power Control) il lumi-
nates when you switch on the ignition as a function check .

Starting and stopping the engine
Starting the engine
The engine can only be started with your original Audi
key.
- Set the parking brake.
- Move the selector lever to the neutral position (automatic
transmission: selector lever in P or N)
=> &.
- On vehicles with manual transmission, fully depress the
clutch pedal.
- Turn the ignition key to position
0 => page 119, fig. 136
- do not depress the gas pedal when starting the engine!
- Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure. This normal
and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
What to do if the engine does not start
• ~ page 304, "Starting with jumper cables"
• ~ page 306, "Emergency towing with commercial tow truck".
& WARNING
Never start or let the engine run in a confined or enclosed area .
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.
0 Note
• Avoid high engine speeds, fast acceleration or heavy engine
loads while the engine is still cold. This could damage the engine.
• The engine cannot be started by pushing or towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emis­
sions, do not let your vehicle stand and warm up. Be ready to drive
off immediately after starting your vehicle. Maintain moderate
speed until the engine is completely warm. Remember, the engine
performs best at operating temperature.•
Stopping the engine
- Turn the ignition key to position (D => page 119, fig. 136.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running . With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up
in the engine
compartment. _,.
