continue to turn the lights on and off using the
light switch. You can still contro l all wiper func­
tions that are independent of the rain sensor .
Drive to an autho rized Aud i dea le r or authorized
Audi Service Facility immediate ly to have the
malfunction corrected.
; Adaptive dampers
Applies to vehicles: with Audi drive select
R Suspension: system fault!
There is an adaptive damper ma lfunction.
D rive to an authorized Aud i dea ler or a uthorized
Aud i Service Facility immediate ly to have the
malfunction corrected.
¢¢Turn signals
If the B or DI indicator light blinks, a turn sig ­
na l is turned on. If both indicator lig hts are blink­
ing, the emergency flashers are on.
I n an indicator light blinks twice as fast as usual
then a blinker bulb has failed. Carefully drive to
your authorized Audi dealer immed iate ly to have
the ma lfunction corrected.

On-Board Diagnostic
system (OBD)
System indicator light (MIL)
The system indicator light (MIL) ¢4 in the instru ­
ment cluster is part of the On Board Diagnostic
System (OBD II).
The warning/indicator light turns on when the ig­ nition is switched on and turns off once the en­
gine is started and is running in idle at a stab le
speed. Th is ind icates that the MIL is funct ion ing
correctly .
If the light does not turn off after starting the
engine
or turns on while driving, this may indi­
cate there is a ma lfunction in the engine. If the
Instruments and indicator lights
indicator turns on, the cata lytic conve rter may be
damaged.
Drive
with reduced engine performance (avoid
high speeds for extended per iods of time and/or
f ast acceleration) and have the malfunction cor­
rected . See an authorized Audi dealer or author­
ized Audi Serv ice Facility.
T he indicator may turn on if the e lectronic speed
limiter is faulty. For add itiona l information, refer
to
¢ page 94, Electronic speed limiter*.
The MIL may also turn on if the fuel filler cap is
not closed correctly ¢
page 192.
On-Board Diagnostics
Fig. 7 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code . In case of a mal function, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
T he M IL light may also illuminate if there is a
leak in the on-board fuel vapor recove ry system.
If the light illuminates after a refuelling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
qpage 192.
In order to make an accurate diagnosis, the stor ­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD).
In order to connect the special diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the right of the hood
release

Driving
Driving
General information
The first 1,000 miles (1,500 km) and
afterwards
The new engine needs to be run-in during the
first 1,000 miles (1,500 km) .
For the first 600 miles (1 ,000 k ilometers ):
.. Do not use full throttle.
.. Do not drive at engine speeds that are more
than 2/3 of the maximum permitted RPM .
.. Avoid high engine speeds .
From 600 to 1,000 miles (1,000 to
1,500 kilometers):
.. Speeds ca n gradually be increased to the maxi­
mum perm issible road or eng ine speed .
During and after break-in period
.. Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in peri od
.. Do not exceed maximum engine speed under
any circumstances.
.. Upshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
opage 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
mov ing parts have been broken in. How well this
break-in process is done depends to a cons idera­
b le extent on the way the vehicle is driven dur ing
the first 1,000 miles (1,500 kilometers).
0 Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
programmed for an engine well run-in, not a
new engine.
@ For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.

· Driving through water on roads
Note the following to avoid veh icle damage when
driving through water, for example on flooded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body .
- Do not dr ive faster than walk ing speed .
A WARNING
After driv ing through water or mud, the brak­
ing effect can be reduced due to moisture on
the brake discs and bra ke pads. A few careful
brake applications sho uld dry off the brakes .
(D Note
Vehicle components such as the eng ine,
transmission, suspension or electrical system
can be severe ly damaged by driv ing through
water .
(D Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driv ing th rough
water .
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid driving through salt wate r (corrosion).
Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fuel economy, env ironmental impact, and wear
on your engine, brakes and tires largely depend
on three factors :
- your personal driving style
- operating conditions
- technical limitations

Airb ag syst em
entered in your Audi Warranty & Mainte­
nance booklet under
AIRBAG REPLACEMENT
RECORD.
- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit interrupter .
- Work on the pyrotechnic circ uit inter rupt­
er must only be performed by a qualified
technicians w ho have the experience, in­
formation and special tools necessary to perform the work safely.
- If the veh icle or the circuit interrupter is
scrapped, a ll applicable safety precautions
must be followed.
@ For the sake of the environment
Undep loyed airbag modu les and pretension ­
ers might be classified as Perchlorate Materia l
- specia l hand ling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate. W hen the veh icle or parts of the re­
straint system including a irbag modules and
safety belts with prete nsioners are scrapped ,
all applicable laws and regulat ions must be
observed. Your authorized A udi dealer is fa­
m iliar with the se requirements a nd we recom­
mend that you have your dealer perform this
service for yo u.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system ca n
change the way that the Advanced A irbag System
performs in a crash. For example, using t ire- rim
combinat ions not approved by Audi, lower ing the
ve hicl e, chang ing the stiffness of the suspension,
includ ing the spr ings, suspension s truts, shoc k
absorbers etc. can change the forces that are
measured by the a irbag sensors and sent to the
e lectronic control unit. Some suspension changes
can, for example, increase the force levels meas ­
ured by the sensors and make the a irbag system
deploy in c rashes in which it wou ld not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
164
the sensors and p revent the airbag from dep loy ­
ing when it shou ld .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
ter istics as the components origina lly instal­
led on you r vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Knee airbags
Description of knee airbag s
Applies to vehicles: with knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants .
Fig. 132 Driver 's knee a irbag
The driver knee airbag is i n the instrument panel
u nderneath the steer ing wheel ~
fig. 132 , the
airbag fo r the passenger is at abou t the same
height in the i nstr ument panel underneath the
glove comp artment.
The knee airbag offers additional protection to
the d river's and passenge r's kn ees and uppe r and
lower thigh areas and supplements the protec­
tion provided by the safety belts.
If the front a irbags deploy, the knee a irbags also
deploy in fronta l co llisions when the dep loyment
