On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ift in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly .
If the light does not go out after the engine is
started, or illuminates while you are driving, a malfunction may exist in the engine system.
If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelera­
tions) and have the condition corrected. Contact
your authorized Audi dealer.
If the light illuminates, the electronic speed lim­iter may also be malfunctioning. For more infor­
mation
¢ page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢

Fig. 17 Loca tion 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 malfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed
¢ page 200.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (gener ic scan tool for OBD).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data L ink Connector
(DLC). The DLC is located to the right of the hood
release

Fig. 75 allroad : Roof rack attachme nt points
"'Always read and follow the instructions provid­
ed by the roof rack manufacturer when instal­
ling the roof rack system.
If luggage or cargo is to be carried on the roof,
you must observe the following :
- Only use roof racks approved for your vehicle .
These approved roof racks are the basis for a
complete roof rack system . Add it ional attach­
ments or carrier systems are needed to trans­
port luggage and sports equipment. We recom­
mend using roof racks from the Audi original
accessories program.
- When insta lling the roof rack, make sure it is
only mounted on the designated locations on
the roof
r::!> fig. 74 or r::!> fig. 75.
- We recommend that you keep the installation
instructions for your roof rack system together
with your Owner's literature in the vehicle .
When should the roof rack be removed?
-Before going through an automatic car wash (it
is best to ask the car wash operator for advice).
- When not in use, to reduce fuel consumption,
wind noise and to guard against theft .
_&. WARNING
- Use of an unapproved roof rack or incorrect
mounting of an approved roof rack can
cause the roof rack or the items attached to
it to fall off the roof onto the road.
- Objects falling from the roof of a vehicle can
cause a crash and personal injury.
- Only mount the roof rack on the designated
locations on the roof
r::!> fig. 7 4.
- The roof rack system must be install ed ex-
actly according to the instructions provided. ..,.

Seat s and sto rage
-When driving with a roo f rack system,
changes to the center of gravity and wind
resistance can change the vehicle handling
and lead to a collision . A lways adapt your
dr iv ing and your speed to the current condi·
t ions .
{U) Note
- Your vehicle warranty does not cover any
damages to the vehicle caused by using roof
racks or mounting structures not approved
by Aud i for your vehicle . The same applies to
damage resulting from incorrect roof rack i nst allation .
- Always check the roof rack mount ings and
hardware befo re each trip and dur ing a tr ip
to make s ure everyt hing is securely tight­
ened.
If necessary, ret ighten the mo unt ings
and check the entire system from time to
time.
- After mounting a roo f rack system, or when
you transport objects on the roof of your ve­
hicle, the height of the veh icle is naturally
i nc reased. Be careful when driving under
l ow bridges or in parking garages for exam­
ple . This could cause damage to the load
and even the vehicle itself.
- Make sure that the open rear lid and the
su nroof do not come into contact with ob·
j ects on the roof .
Loading the roof rack
Always distribute loads evenly. Make sure any ­
thing on the roof rack is securely tied down .
"'Always distribute the loads on the roof rack
evenly .
"' Always attach items to the roof rack securely
before you dr ive off .
The max imum perm issible roo f weight is
2 00 lb
( 90 kg ).
The roof weight is the total of the
weight of the roof rack, the attachme nts and the
cargo you are carrying . You must also not exceed
the maximum load weight fo r the roof rack yo u
a re using.
68
When using a roof rack system wh ich has a lower
l oad carrying capacity, you must not use up the
total max imum permissib le load carry ing capac i­
ty specified above. Instead, you should load the
roof rack sys tem only to the maximum capacity
specified by the manufacturer of the roof rack
system.
A WARNING
Weak, damaged or improper straps used to
secure items to the roof rack can fail du ring
hard brak ing or in a collision and cause seri­
ous persona l injury .
- Ma ke sure the roof rack is i nstalled exactly
as spe cified above
~ page 67 .
-Always use suitable mo unt ing straps fo r se·
cur ing items to the roof ra ck to help preven t
items from sh ifting or flying forward .
- Items on the roof rack must a lways be se·
cure ly mounte d.
- The use of a roof rack can negative ly affect
the way a vehicle handles . Cargo that is
large, heavy, b ulk y, long or flat w ill have a
greater negative influence on the vehicle's
aerodynamics, center of grav ity and overa ll
handling . Always drive slowly, avoid sudden
braking and maneuvers when transporting
cargo on the roof of your vehicle .
- Never exceed the maximum permissib le
load carry ing capacity of the roof of your ve­
hicle, the perm iss ible axle weights and the
perm iss ible total we ight of your vehicle
~ page 255, Weights.
(D Note
Make sure that the opened rear lid does not
come in contact with the cargo on the roof .
@ For the sake of the environment
As a result of the increased wind resistance
created by a roof rack, your vehicle is using
fuel unnecessarily . So remove the roof rack
after using it .

Climate control system
Description
The climate control system warms, cools and
adds humidity to the air in the veh icle inter ior. It
is the most effective when the windows and sun ­
roof are closed. If there is a build-up of heat in­
side the vehicle, ventilation can help to speed up
the cooling process.
I n all heating mode functions except
defrost, the
b lower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture .
Condensat ion from the cooling system can drip
and form a puddle of water under the veh icle.
This is normal and does not mean there is a leak.
P ollutant filt er
The pol lutant filte r removes pollutants such as
dust and pollen from the a ir.
The air pollutants filter must be changed at the intervals specif ied in your Warranty
& Mainte­
nance booklet, so that the a ir cond it ione r can
properly work.
If you drive your vehicle in an area with high air pollut ion, the filter may need to be changed
more frequently than specified i n your Aud i War­
ranty
& Maintenance booklet. If in doubt, ask
your author ized Audi Service Advisor for advice.
Ke y cod ed setting s
The climate control settings are automatically
stored and assigned to the remote control key
that is in use .
.8, WARNING
Reduced visib ility is dangerous and can ca use
accidents.
- For safe dr iv ing it is very impo rtan t that all
windows be free of ice, snow and condensa­
t ion .
76
- Complete ly familiarize yourself with the
proper use and function of the heating and
ventilation system and espec ially how to de­
fog and defrost the wi ndows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­ ing and vent ilation system. The washer solu­
tion may freeze on the windshield and re­
duce visibi lity.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid further damage and have it inspected
by a q ualified dealership.
- Repa irs to the Aud i air cond itioner requ ire
special techn ica l know ledge and spec ial
tools. Contact an a uthorized Audi dealer fo r
assistance.
@ For the sake of the environment
By reduc ing the amo unt of fuel you use, you
also reduce the amount of pollutants emitted
into the a ir.
(D Tips
- Keep t he a ir intake slots (in front of the
windshield) free from ice, snow and debr is
in orde r to maintain the prope r funct ion of
the climate control system .
- The energy management sys tem may sw itch
the seat heating* o r rea r window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of clothing on
the luggage compartment cover, ensure
that the openings are not covered.

tiptronic
Introduction
Applies to vehicles : wi th mult itro nic/S tro nic/ tip tronic
The automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depend ing o n which drive
program is se lected .
When a
moderate driving style is used, the
transm ission selects the most economica l driv ing
mode . It will the n change up early and delay the
downshifts to give better fuel economy .
The transmission switches to a sporty mode after
a kick-down or when the driver uses a
sporty
dri ving style
characterized by quick accelerator
pedal movements, heavy acceleration, frequent
c hanges in speed and traveling at the maxim um
speed.
If desired, the driver can also select the gears
manually (tiptronic mode ) ¢ page 90.
Various automatic transmissions may be insta l­
l ed, depending on the model :
multitronic transmission
The mu ltitron ic t ransm iss ion is a continuously
variable transmission. Power is transferred using
a multidisk cl utch . In contrast to conventional
automat ic transmissions using shifting opera­
tions, the transmission ratio in the continuously
variable transmission is changed continuously.
This opt imizes the comfort leve l and conserves
fuel.
S tronic t ran smission
The S tronic is a d ua l-clutch transmission. Power
i s transferred using two clutches that work inde­
pendently from one another . They rep lace the
torque converter used in convent io nal automatic
transm issions and allow the vehicle to accelerate
withou t a noticeable inte rru pt io n in traction. ..,.

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1 ,000 kilometer s):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1 ,000 to 1 ,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum pe rm issib le road or engine speed .
During and after break-in pe riod
"' 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 period
"'Do not exceed maximum engine speed under
any c ircumstances.
"'U pshift into the next higher gear

During the first few hours of driving, the eng ine's
internal friction is higher than later when all the
mov ing parts have been broken in . How well this
b reak-in process is done depends to a considera­
b le exte nt on the way the veh icle is d rive n during
t he first 1,000 miles (1,500 kilometers).

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.
F ue l economy, environmenta l impact, and we ar
on your engine, brakes and tires la rgely depend
on three factors :
- you r persona l dr iving sty le
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your fue l
consumption by
10-15 percen t. This section will
g ive you some tips on how you can help the envi ­
ronment and yo ur pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not cor re­
spond to your actual consumption on the
road, which will va ry depending upon vehicle
load and speed, road and wea ther condi tions,
t rip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating a nd braking .
Veh icles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next , you will need to brake less and, thus, accel­
e rate less . let the vehicle coast wheneve r possi ­
b le -fo r example when yo u see that the next traf­
fic light is red .
Driving and the envir onment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car 's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fuel consumption, exhaust emissions and engine
noise increase disproport ionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted
speed limit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad cross ings, or at traff ic lights that have long waits
on red . Turning the engine off for just
30 -40 sec ­
onds saves more f uel than is burned starting the
. . engine again.
It takes a long time for the eng ine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially h igh when
the engine is warming up . So yo u should dr ive
away as soon as you start the eng ine and avoid
runn ing at high rpms w hile the engine is st ill
warming up .
(D Note
Do not leave eng ine idling unattended after
s tart ing. If wa rning lights sho uld come on to
i ndicate improper operation, they would go
unheeded . Extended idling also prod uces
heat, which could resu lt in overheating or
other damage to the vehicle or other proper­
ty.
