On-Board Diagnostic
system (OBD)
On-Board Diagnostics
Fig. 25 Locat ion of Data Link Connecto r (DLC)
On-Board Diagnostics monitors the compo­
nents of you r emission control system. Each
monitored compo nen t in your eng ine system
has been assigned a code . In case of a ma l­
function, the component will be identified
and the fau lt stored as a code in the control
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 refuelling,
stop the vehicle and make sure the fuel filler
cap is properly closed ¢
page 176.
In o rder to make an accurate diagnosis, the
stored data can only be displayed using spe­
cia l diagnostic equipment (generic scan tool
for OBD).
I n o rder to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the hood release¢
fig. 25.
Your authorized Audi dea ler or a qualified
service station can interpret the code and per­
form the necessary repair .
Malfunction Indicator lamp (MIL)
The Malfunction Indicator Lamp (MIL) &'I in
the instrument cluster¢
page 13, fig. 6 is
part of the On-Board Diagnostic COBO II) sys­
tem .
The warning/indicator light illuminates when
the ignit io n is switched on and goes out after
the e ngine starts and the idle has stabilized.
Th is indicates that the MIL is working prope r­
ly.
If th e light d oes not go out after the engine
is started, or illum inates wh ile you are dr iv­
ing, a malfunc tion may exist in the engine sys­
tem.
If the light illum inates, the catalytic con­
verte r could be damaged .
Continue driving
with reduced p ower (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the cond ition corrected.
Contact you r authorized Audi dea le r.
If the light illum inates, the electronic speed
limi ter may also be malfunct ioning . For more
i nformation ¢
page 28, Electronic speed
limiter.

cau se the MIL light to illuminate
¢ page 176.
Electronic speed limiter
Your vehicle may be factory eq uipped w ith
tires that are rated for a maximum speed of 130 mph (210 km/h) . This is less than the
maximum speed of your vehicle. To reduce the
risk of sudden tire fai lure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle a lso has an electronic speed limit­
er . The electronic speed limiter prevents your
vehicle from going faster than the tire speed
rating. Fo r more information
¢page 205. ...,

If the engine control unit receives fau lty vehi ­
cle roadspeed signa ls , the Ma lfunction Indica­
tor Light (MIL)
Ill will illum inate . If th is oc­
curs, contact the nearest authori zed Audi
dealer for assistance.

@ Tips
If the L ED in the sw itch stays on a fter A/C
operation has been switched off( = sw itch ­
ing the A/C off), there is a fault in an air
conditioning component. P lease cons ult
an authorized Audi dealer when there is an
operating problem.
Using the climate controls economically
E conomical use of the climate controls helps
to save fuel.
When climate control is wo rking in cooling
mode, engine performance is reduced and
fuel consumpt ion is affected. To keep the time
the air cond ition ing is on as short as poss ible,
you should do the following: .,,_

~ If you would like to save fuel, switch the air
conditioning off.
~ If you open the windows wh ile driving,
switch the air conditioning off.
~ If the vehicle is extremely hot due to the
heat of the sun, briefly open doors and win­
dows.
@ For the sake of the environment
When you save fuel, you reduce em iss ions
from the vehicle.
Rear window defogger
The rear window defogger clears the rear win­
dow of condensation .
~ Press the QiP button c:> page 75, fig. 87 to
turn the rear window defogger on and off.
The rear window defogger works only when
the eng ine is running. The indicator light in
the button illuminates when the rear window
defogger is turned on .
The rear window defogger is switched off au­
tomatically after 10 to 20 minutes, depend­
ing on the outside temperature.
At very low outside temperatures, the rear
window defogger can be switched on continu­
ously by push ing the
QiP button for more than
2 seconds. This remains stored unt il the igni­
tion is sw itched off . A rear window defogger
that was switched on a lso remains stored for
15 minutes after the ignition is switched off.
If the engine is restarted within these 15 m i­
nutes, the rear window defogger is act ivated
for 10 to 20 minutes, depending on outside
temperature. With a vehicle that is parked for
a short t ime, the rear w indow defogger does
not need to be manually activated again.
@) For the sake of the environment
As soon as the rear window is clear, yo u
should switch the rea r window defogger
off . The reduced power consumption has a
beneficial effect on fuel consumption.

Heated seats
Applies to vehicles: with heated seats
The seat cushion and the seatback of the
front seats can be heated electrically.
~ Press the heated seats button I -.i + I
<=> page 75, fig. 87 to set the level of heating
desired.
The range of contro ls goes from 1 to 3. The
heat setting selected is shown by LEDs above
the button.
(D Note
To avoid damage to the heating e lements
in the seats, do not kneel on the seats or
place heavy loads on a small area of the
seat.

(D Note
Only after the vehi cle has come to com­
plete stop, should you f irm ly set the park­
ing brake and either move the selector lev­
er into "P".
Parking
To prevent a parked vehicle from rolling
away, there are a few things you should do.
When you park your vehicle, do the following:
.,. Stop the vehicle using the brake pedal.
... Set the parking b ra ke firmly .
... Switch
off the engine.
... Move the selector lever into the P position
¢ A .
... Remove the ign it ion key from the ignit ion
lock.
What else you should do when pa rking
your vehicle on an incline or decline
Turn the steering wheel so that if the vehicle
should start to roll, it will roll into the curb.
If you are parking on a decl ine (the front of
your vehicle facing downhill), turn the front
wheels to the right so that they point
toward
the curb.
If you are parking on an incline (the font of
your vehicle facing uph ill), turn the front
wheels to the left so that they po int
away
from the curb.
A WARNING
Th is is how you can reduce the risk of in­
jury when leaving your veh icle.
- Never park the vehicle where it can come
in contact with d ry grass, sp illed fuel or
any othe r flammable mater ials .
- Never allow anyone -especially small
children -to remain in the vehicle whe n
it is locked . Locked doors ma ke it more
difficult for rescuers to access the pas­
senge r compartmen t in the event of an
eme rgency. Danger to life!
- Never leave c hildren unsupervised in the
vehicle. Children co uld re lease the par k-

ing brake or move the gearsh ift leve r out
of gear. The vehicle could start to ro ll
away and cause an acc ident.
- No matter what the season is, the tem­
perature in a parked ve hicle can reach
dangerous leve ls.
Acoustic parking
system
' Rear acoustic park assist
Applies to vehicles: with 4-channel acoust ic park assist
Acoustic park assist gives a warning about
obstacles behind the vehicle .
Description
The rea r acoustic pa rk ass ist (4-channel
a coustic park ass ist) de termines the dista nce
of the vehicle from an obstacle using ult ra ­
son ic sensors. The sensors are in the rear
bumper. The volume and the pitch of the
c hi mes can be adjusted throug h the men u dis­
play¢
page 21.
T he range at wh ich the sensors start to meas ­
u re is
about :
To the side
Activation
2 feet (0.60 m)
5 feet (1.60 m)
T he park ing ass ist is activated when
rever se
g ear
is engaged. A br ief tone confirms th at
the sys tem is activated .
Backing up
Distance warning whe n backing up sta rts
whe n an obstacle is detected in the range of
t he pa rk ass ist system. As the distance de­
c reases, the t ime inte rva l between the audible
tones becomes shorte r.
When the distance is less than 1 foot (0.30
m), the tone becomes continuous. At this
po in t you sho uld s top bac king up .
Please note that low objects already signalled
by a war ning ca n disappear from the system's
de te ction range and will not continue to be
s ignalled . .,._

158 Driving and en vi ro nm ent
Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc ., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) and fully loaded
vehicles .
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any highe r tha n the
bottom of the vehicle body.
- Do not d rive faster than wa lking speed.
_& WARNING
After d riving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(]) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys ­
tem can be severely damaged by driving
through water.
- Check the depth of the water before driv ­
ing through it.
- Do not stop the veh icle, drive in reverse
or switch the engine
off when driving
through water.
- Keep in mind that oncoming vehicles may create waves that raise the water
level and make it too deep for your vehi­
cle to drive through safely.
- Avoid driving thro ugh salt water because
it can ca use corrosion.
-
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
.. Always use lead-free gasoline ¢ page 17 4,
Fuel supply .
.. Never run the tank down all the way to emp­
ty.
.. Never put too much motor o il in your eng ine
r::;> page 183, Adding engine oil~-
.. Never try to p ush- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean­
up" dev ice built into the exhaust system of
t h e vehicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be ­
f ore they are re leased into the atmosphere.
T he exclusive use of unleaded fuel is critically
impor tant for the life of the catalyt ic convert­
er and prope r funct ion ing of the engine.
A WARNING
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additiona l undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat sh ields. Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already ser iously de-
grade the performance of the catalytic
converter .
- Do not exceed the correct engine oil level
¢page 183.
-Do not drive until the fuel tank becomes
completely empty . The engine could mis-
fire. Unburned fuel could also get into ..,.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not con tinue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reac h the cata lytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, t he exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 159
fuel consumption by 10 -15 percent. This sec ­
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as publishe d
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"' Try and keep well below your car's maximum
speed.
Acce lerat ing gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at app roximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Nev er drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

160 Driving and en vi ro nment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic l ights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . However , wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high RPMs whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate imp roper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dea ler helps to ensure that it runs prop­
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ability to
hold its value, it also affects fuel consump­
tion .
Check you r oil ea ch time you fill you r tank. T
he amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometres) before yo u can properly
assess oil consumpt ion.
T his also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved
by the manufacturer.
- Do not alter or remove any device, such
as heat sh ie lds, switches, ign it ion w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal operat ing temperature to
reduce fuel consumption and nox ious emis­
s ions effectively .
- Ju st after starting, a cold engine in a mid­
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road , the mileage improves
to 12 MPG (20 l/100 km). It w ill take the
ll>

engine no less than two and a half miles
(4 km) of driving to warm up to its proper
operating tempe ratu re and ope rate at an
economic mileage. This explains w hy taking
t h e car for s hort tr ips is a rather wastefu l
convenience .
- The
outs ide temperature is also cr itical in
t hi s regard. Your car consumes more fuel in
the winter than in the summer .
Trailer towing
