30 Instruments and warning /indicator lights
has been assigned a code. In case of a ma l­
function, the component will be identified
and the fault stored as a code in the contro l
module memory.
The MIL light may a lso illuminate if there is a
leak in the on-board fue l vapor recovery sys­
tem .
If the light illuminates after a refue lling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢
page 219.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe­
cial diagnostic equipment (generic scan tool
for OBD) .
In order to connect the special diagnostic
equipment, push the plug into the Data L ink
Connector (DLC). The DLC is located to the
right of the hood release¢
fig. 16.
Your authorized Audi dealer or a qualified
service station can interpret the code and per­
form the necessary repair .
A WARNING
Do not use the diagnostic connector for
personal use . Incorrect usage can cause
malfunctions, which can increase the risk
of a coll ision!
Electronic speed limiter
-
Your veh icle may be factory equipped with
tires that are rated for a maximum speed of
130 mph (210 km/h). This is less than the
maximum speed of you r vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your veh icle also has an electronic speed limit­
er. The electronic speed limiter prevents your
vehicle from go ing faster than the tire speed
rating. For more informat ion ¢
page 260 .
If the engine control unit receives faulty vehi­
cle road speed s ignals, the Malfunction Indi­
cator Lamp (MIU
¢'4 will illuminate. If this
occurs, contact the nearest authorized Aud i
dealer for assistance. S models
Your
vehicle's top speed is elect ron icall y limit­
ed to 155 mph (250 km/h).
If the engine control unit receives faulty veh i­
cle roadspeed signals, the Malfunction Indica­
tor Lam p (MIL)
¢'4 will illuminate . If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.
_& WARNING
-= -
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather cond itions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed .

visibility conditions. For example, fog cannot be detected by the light sensors.
So always switch on the headlights 1§.D under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists . Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.
- Please observe legal regulations when
using the light ing systems descr ibed .
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
@ Tips
- The light sensor* for automatic head­ light range control* is located in the rear
view mirror mount. You should therefore not apply any stickers to the windshield
in this area in order to prevent malfunc­
tions or failures.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display ¢
page 23 .
-You will hear a warning tone if you open
the driver door when the exterior lights
are switched on .
- In cool or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting .

- The w indshie ld m ust not be treated with
water -repe llent materials. They can in­
c rease glare under poor visibi lity condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. I n addi­
tion, they can cause the windshield wip­

t h e windshie ld. Switching on the wind­
s h ield wipers can damage the wiper
blades!
- Prior to using a car wash, the win dsh ield
wipe r system must be switched off (lever

you can select if the mirrors fold in automati­
cally when you lock the vehicle ~
page 34.
Tilt function for the passenger's mirror
To help you see the curb when backing into a
parking space, the surface of the mirror tilts
slightly. The knob must be in the P position
for this to happen.
You can adjust the tilted mirror surface by
turning the knob in the desired direction.
When you move out of reverse and into anoth­
er gear, the new mirror position is stored and
assigned to the key you are using.
The mirror goes back into its original position
once you drive forward faster than 9 mph (15
km/h) or switch the ignition off.
.&_ WARNING
- Curved (i.e. convex) mirror surfaces in­
crease your field of view. Remember that
vehicles or other objects will appear
smaller and farther away than when seen in a flat mirror.
If you use this mirror to
estimate distances of following vehicles
when changing lanes, you could estimate
incorrectly and cause an accident.
(D Note
-If the mirror housing is moved uninten­
tionally (for example, while parking your
vehicle), then you must first fold the mi r­
ror electrically. Do not readjust the mir­
ror housing manually. You could damage
the motor which controls the mirror.
- If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
the mirrors. Never fold power folding ex­
terior mirrors* by hand. Only fold them in and out using the power controls.
@ Tips
-The exterior mirror settings are stored
with the memory function*
~ page S 7.
- If there is a malfunction in the electrical
system, you can still adjust the exterior

mirrors by pressing the edge of the mir­
ror.

&_ WARNING
= Electrolyte fluid can leak from automatic
dimming mirrors if the glass is broken.
Electrolyte fluid can irritate skin, eyes and
respiratory system.
~
- Repeated or prolonged exposure to elec­
trolyte can cause irritation to the respira­

with asthma or other respiratory condi­
tions. Get fresh air immediately by leav­
ing the vehicle or, if that is not possible,
open windows and doors all the way.
- If electrolyte gets into the eyes, flush
them thoroughly with large amounts of
clean water for at least 15 minutes·

A WARNING
-Never adjust the driver's or front pas­
senger's seat while the vehicle is moving.
If you do th is while the veh icle is moving,
you will be out of position . A lways adjust
the dr iver's or front passenger's seat
when the vehicle is not moving.
- Be careful when adjusting the seat
he ight. Check to see that no one is in the
way, or ser ious injury cou ld resu lt!
- Because the seats can be electrically ad­
justed with the igni tion off, never leave
children unattended in the veh icle. Unsu­
pervised use o f the electric seat adjust­
ments may cause serious injury.
- To reduce the risk of injury in the case of
sudden braking or accident, front pas­
sengers must never ride in a moving ve­
hicle with the backrest reclined. Safety
belts and the airbag system only offer
maximum protection when the backrest
is upr ight and the safety belts are prop­
erly positioned on the body . The more
the backrest is reclined, the greater the
ris k of persona l inju ry from an incorrect
seating position and improperly posi­
tioned safety belts.
(D Tips
- T he massage funct ion switches off auto­
matically after approximately 10 mi­
nutes.
- T he side bolsters* deflate when the driv­
er's doo r is opened. This allows you to
enter and exit comfortably. The side bol­
