On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) II in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabi lized .
This indicates that the MIL is working proper­
l y.
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing, a malfunction may exist in the engine sys- tern.
If the
light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your authorized Audi dea ler.
If the light illuminates, the electronic speed
limiter may also be malfunct ioning. For more
information
q page 31, El ectronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
~page 213.
On-Board Diagnostics
Fig. 18 Locat ion of Data L ink Connector (DLC)
On-Board Diagnostics monitors the compo­
nents of your em ission control system . Each
monitored component in your engine system
has been assigned a code . In case o f a mal­
function, the component will be identified
and the fault stored as a code in the control
module memory.
T he MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem.
If the light illuminates after a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed

Homelink®
Universal remote
control
Description
Appl ies to vehicles: with Horne Link
The Homelink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
l ights, etc. comfortab ly from the inside of you
vehicle .
H ome Link makes it possible for you to rep lace
three differen t remote controls from dev ices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes p lace near the center of the radiator
grille. There is a control module attached at
this location.
A one-t ime programming of the sensor must
be performed before you are able to use sys­
tems with Homelink. If the system does not
activate after performing the one-t ime pro­
gramming, check whether the system uses a rolling codec:>
page 122 for veh icles without
the MMI*.
_& WARNING
- Never use the Homelink ® transmitter
with any garage door opener that does
have not the safety stop and reverse fea ­
ture as requ ired by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards. Us ing a garage door
opener without these features increases
risk of serious injury or death.
Homelink ® 119
-For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle.
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink ® remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its e lectrical components -an
overheated motor is a fire hazard!

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new
b rake pads do not possess their fu ll braking
effect , they have to be "broken in" first¢.&. .
You can compensate for this slightly reduced braking power by push ing harder on the brake
pedal. Avoid heavy braking loads during the
break-in per iod.
Operating condition s and d riv ing hab it s
The brakes on today's automob iles are st ill
subject to wea r, depending largely on operat­
ing conditions and driving habits¢.&. . On
vehicles that are e ither driven mostly in stop­
and-go city traffic or are driven hard, the b rake pads should be checked by your author­
ized Audi dealer more often than specified in
the
Warranty & Maint enan ce booklet . Failure
to have your b rake pads inspected can res ult
in red uced brake pe rformance.
On steep slopes, you shou ld use the brak ing
effect of the engine. This way, you p revent un­
necessa ry wear on the brake system. If yo u
must use yo ur brakes, do not hol d the brakes
down continuously. P ump the brakes at inter ­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, brak ing fo rce and outside condi­
tions such as temperature and humidity.
Effect of water and road salt
In ce rtain situat ions, for example after driving
through water , in heavy ra in, after overn ight
conde nsation or afte r washing your car, the
b rak ing effect can be redu ced by mois ture or
ice on the brake rotors and brake pads . The
brakes must be dried first with a few careful
brake applications .
A t higher speeds and with the w indshield w ip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time .
This occurs at regular intervals witho ut the driver noticing and p
rovides fo r bette r brake
response time under wet conditions .
T he effec tiveness of the brakes can be red uced
when the vehicle is d riven on a sa lt -covered
r oad and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautio us ap­
plicat ions of the brake ¢ .&. .
Corro sio n
The re may be a tendency for di rt to b uild up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or only fo r short trips w ith litt le use of the
brakes.
If the brakes are not used frequently, o r if cor ­
rosion has formed on the discs, it is advisable
to clean off the pads and d iscs by braking
firmly a few times from a moderately high
speed ¢.&. .
Fault s in the brak e syst e m
If you s hou ld notice a sudden increase i n
brake pedal trave l, then one of the two brake
c ircuits may have failed ¢.&. .
Low brake fluid level
Malfunctions can occ ur in the b ra ke system if
the brake fluid level is too low. The brake fluid
l evel is monitored electronica lly.
Brake booster
T he bra ke booster inc reases the pressure that
you generate wi th the b rake peda l. It works
o n ly when the engine is runn ing .¢ .&.
Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
th rough the ope nings in the wheel. If neces­
sary, the wheel may be removed for t his in­
spect ion ¢
page 253, Changing a wheel.
_& WARNING ,____
-New b rake pads don't have the best stop­
p ing power and m ust be "broken-in" dur-
ing the initial 100 to 150 miles (150 to

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on t he veh icle's chassis at a
technically sound location . Use only a t railer
h itch w ith a removab le ball moun t. A lways
check with the tr ailer hitch man ufac tur er to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitc h must be installed in such a way that
it does not inte rfe re with the impac t-absorb­
i ng b umper syst em. No modifica tions should
be made to the vehicle exhaus t and b rake sys­
tems . From t ime to time, check that a ll hitch
mo unt ing bolt s remain securely fas tened.
W hen you are not tow ing a trailer, remove the
trai le r hi tch ball moun t. T h is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from be hind
¢ &. .
Trailer brakes
If yo ur tra iler is equ ipped w it h a braking sys­
tem, check to be su re that it conforms to a ll
r eg ulat io ns.
Trailer towin g 197
The trailer hyd ra ulic bra ke system must not be
direct ly connected to the vehicle's hydraulic
brake system
¢ &. .
Safety chains
Alw ays use s afety chains between your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r lights m ust meet all reg ulations . Be
su re to check w ith your authorized Audi dealer
fo r c orrec t w iri ng, sw itches, and relays.
Mirrors
If you a re unable to see the traffic behind you
u sing the regula r outside m irrors, then you
must insta ll ext ended mir ro rs. It is important
t h at you
always have clea r vis io n to the rear .
.8, WARNING
- If a trai ler has elec trica l br ake s plea se
no te th at t hese bra kes are not activat ed
by the fa ctory -fit ted control unit -risk of
accident!
- After removing the t railer hi tch, do no t
s to re it in yo ur vehicle . In case of sudden
brak ing, the hitch could fly fo rward and
in ju re you or yo ur passenge rs .
Operating instructions
Maximum traile r we ight
-
A trai ler fo r you r vehicle is limited to a typical
class 1 or class 2 tra iler.
Trailer load distribution
B e sure the lo ad in the tra iler is h eld secure ly
i n p lace to p reven t it from shifting fo rward,
backward or sideways.
Never allow a passenger to ride in a trailer

198 Trailer towing
Tire pre ss ure
When towing a trai le r, inflate the t ires of your
vehicle to the co ld tire pressure listed under
"Full load" on the label located on the driver 's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac ­
turers' specifications.
Light s
The headlight settings should be checked with
the trailer attached before dr iving off. Check
to make sure both vehicle and tra iler lights
are working properly.
Saf ety chains
Be sure tra iler sa fe ty cha ins a re p roperly con­
nected from the trailer to the hitch on the ve ­
hicle. Leave eno ugh slack in the chains to per ­
mit turning corners. When you install safety
cha ins, make sure they w ill not drag on the
road when you are driving.
The chains shou ld cross under the trai ler
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best possible handling o f vehicle
and trai ler, p lease note the following:
.,. Do not tow a loaded tra iler whe n your car it ­
self is no t loaded .
.,. Be especia lly careful when passing other
vehicles .
.,. Observe speed limits .
.,. Do not drive at the maximum permissible
speed.
.,. Always apply brakes early .
.,. Monitor the temperature gauge.
Weigh t di stribution
Towing a loaded trai ler with an empty car re­
sults in a highly unstable distribution of
weight . If this cannot be avo ided, drive at very
low speeds only to avoid the risk of losing
steer ing control. A "ba
lanced' ' rig is easier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keep ing the trai ler as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com ­
partment of the tow veh icle while obse rving
tongue load requ irements and vehicle load ing
considerations.
Speed
The higher the speed, the more d iff icu lt it be­
comes for the driver to control the rig. Do not
drive at t he maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -pa rtic ularly
whe n going downhill.
Reduce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do n ot
try to sto p th e swaying by acc elerating .
Observe speed limits. In some areas, speeds
fo r vehicles tow ing tra ile rs a re lower than for
regular veh icles .
Always apply brakes early. When driving downh ill, shift into a lower gear to use the en ­
gine braking effect to slow the vehicle . U se of
the brakes alone can cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge c> page 10
must be observed carefu lly. If the needle
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warning light •
i n t he i nstrument cluster starts flashing, pull
off the road, stop and let the engine
idle for
abo ut two min utes to prevent he at build-up .
_& WARNING
Anyone not proper ly restra ined in a mov ­
i ng vehicle is a t a much greater risk in an
accident . Never let anyone ride in yo ur car
who is not p roperly wea ring the rest raints
prov ided by Audi.

Engine oil
· Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
The eng ine in your Audi is a sophist icated
power plant that was b uilt to exacting specifi­
cations . Th is engine needs the right k ind of
engi ne oil that meets specifica tions regard ing
quality a nd v iscosity so that it can run
smooth ly and reliab ly. Choosing the rig ht o il
and changing oil within the t ime and mile age
i n tervals prin ted in you r vehicle's Warr anty
&
Maintenance booklet matters a lot more to ­
day tha n it did years ago . Aud i has deve loped
a spec ia l quality standard for engine oil that
will help assure that your vehicle 's engine w ill
get the lubr ication it needs for proper opera-
t ion . ..,_

220 Check ing and filling
temperatures stay below freezing point for
long periods.
Detergent addit ives in the o il w il l make fresh
oil look dark after the eng ine has been run­
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am age or m alfunc tions du e to lack of
m ainten ance
It
is essential that you change your oil at the
recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cool ing of internal engine components, a ll in­
ternal combustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 193) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to wear as mi
leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see
Note .
If
the yellow engine oil leve l warning symbo l
I! in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le
