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 ¢

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

-Objects fal ling 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
c:> fig . 65.
- The roof rack system must be installed ex­
act ly according to the instructions provided .
- 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. Always adapt your
dr iv ing and your speed to the current condi­
t ions .
- Your vehicle warranty does not cover any
damages to the vehicle caused by using roof
racks or mounting structures not approved
by Audi for your vehicle . The same applies to
damage result ing from incorrect roof rack
i nstallation .
-Always check the roof rack mount ings and
hardware before each t rip and dur ing a tr ip
to make sure everyt hing is securely tight­
ened.
If necessary, ret igh ten the mo unt ings
and c hec k the en tire system from time to
time.
- After mounting a roof rack system, or when
you transport objects on the roof of your ve ­
hicle, the height of the vehicle is naturally
increased . 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 s ure that the open rear lid and the
sunroof do not come into contact with ob­
jects on the roof .
Loading the roof rack
Always distribu te loads evenly. Make sure any­
thing on the roof rack is securely tied down.
~ Always distribute th e loads on the roof rack
evenly .
~ Always attach items to the roof rack securely
before you drive off .
T he maximum perm iss ible roof weight is
165 lb
( 75 kg ). The roof weight is the total of the
Seat s and sto rage
weight o f the roof rack, the attachments and the
cargo you ar e carrying. You must a lso not exceed
the max imum load weight for the roof rack you
are using.
When using a roo f rack system which has a lower
load carry ing capacity, you must not use up the
total max imum permissible 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 imprope r straps used to
secure items to the roof rac k can fail d uring
hard brak ing o r in a co llision and cause seri ­
ous persona l injury.
- Make sure the roof r ack is installed exactly
as specified above
c:> page 62.
- Always use suitable mounting straps fo r se­
cur ing items to the roof rac k to he lp prevent
items from shifting o r flying forward .
- Items on the roof rack mus t always be se ­
curely mounted.
- The use of a roof rack can negative ly affect
the w ay a vehicle hand les . Cargo tha t is
large, heavy, b ulk y, long or flat wi ll have a
grea ter negat ive infl uence on the vehicle's
aerodynamics, center of gravity and overa ll
handling. Always drive slowly, avoid sudden
braking and maneuvers when transporting
cargo on the roof of your vehicle.
- Never exceed the max imum permissib le
load carrying capacity of the roof of your ve­
h icle, the permiss ible axle weights and the
perm iss ible total we ight of your vehicle
c:> page 241, Weights .
@ For the sake of the environment
As a result of the increased wind res istance
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 .
68
-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.

Introduction
Applies to vehicles: with S tronic/tip tronic
The au toma tic transmission is con trolled ele c­
tronically . The transmission upshifts or down­
shifts automatically depending on which drive program is se lected.
When a
moderate driving sty le is used, t he
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 tra nsmission sw itches to a sporty mode after
a kick-down or when the driver uses a
s porty
dri ving style
characterized by quick accelerato r
pedal movements, heavy acceleration, frequent
changes in speed and traveling at the max imum
speed .
If desired, the d river can also select the gears
manually (tiptronic mode ) ~ page 86.
Various automat ic tr ansmissio ns may be insta l­
l ed, depending on the model :
S tronic transmission
The S tronic is a dual-clutch transmission . Power
i s transfer red using two clu tches that wor k inde­
pendently from one another. They rep lace the
torque conve rter used in conven tiona l automatic
transm iss ions and allow the ve hicle to accelerate
without a noticeable interruption in traction.
tiptronic transmission
In the tiptroni c transmission, power is t ransfe r­
r ed by a torq ue conve rter.

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
before reach­
ing the red area at the end of the tachometer
sca le
c=>page 10.
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).
(D Note
Extremely high eng ine speeds a re au toma ti­
cally reduced. However, these rpm limits are

Driving and the envir onment
New tires
If your vehicle is runn ing on new tires, d rive very
car efu lly fo r the firs t 35 0 miles (500 kilometers)
a ft er fit ting.
New tires tend to be slippe ry and must a lso
be "bro ken-in". Be sure to remembe r th is dur­
i ng the fi rst 350 m iles (500 kilometers).
Brake gent ly. Avoid following closely behind
other vehicles or other s ituations that m ight
r equire sudden, hard b raking.
Avoid damaging the
vehicle
When yo u are dr iv ing o n poor roa ds, or over
cur bs, stee p ramps, e tc., ma ke cert ain that low­
ly ing parts s uch a s spo ile rs a nd exh aust sy stem
parts do no t bottom o ut and get dama ged.
T his is espec ially true for ve hicles with low-s lung

vehicles.
Driving through water on
roads
Note t he following to avoi d ve hicle damage w hen
driv ing through water, for examp le on flooded
roads:
- The water must not be any hig her t han the bot ­
tom of the vehicle body.
- Do not dr ive faste r than walk ing speed.
A WARNING

177

Driving and th e en vironm ent
(D Tips
- Check the depth of the water before driving
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 veh icle to drive
through safely.
- Avoid driving through salt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline ¢ page 186,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 195, 9::?1 Adding engine oil .
~ Never try to push- or tow-start you r vehicle.
The cata lytic converter is an efficient "clean-up"
dev ice bu ilt into the exha ust system of the vehi­
cle. The cata lytic conve rter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the life of the catalytic conve rter and
p roper functioning of the engine.
A WARNING ,..____ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park or ope rate t he vehicle in areas
where the hot exha ust system may come in
contact with dry grass, br ush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani-
178
fold, exha ust pipes, cata lytic conve rter or
heat shields. D uring driving, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl) Note
- Be aware that just one tank f illing wit h
leaded fu e l w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l
¢page 195.
-Do not drive until the fue l tank becomes
completely empty. The engine could mis­
fire. Unbu rned fue l cou ld also get into the
exhaust system and this could cause the
catalytic converter to overheat.
- Do not turn off the ign ition while the vehicle
is moving .
- Do not continue to operate your vehicle un­
der these conditions, as otherw ise fuel can
reac h the catalytic converter. T his could re­
sult in overheat ing of the converter, requir­
ing its replacement.
- T o ass ure eff icient operat ion of the Emis­
sion Contro l System:
- Have you r vehicle maintained properly and
i n accordance wit h the service recommen­
dations in your Warranty
& Ma intenance
booklet.
- Lack of proper ma intenance as well as im­
p roper use of the veh icle will impa ir the
function of the emission control system
and could lead to damage.
(® For the sake of the environment
Even when the Emiss ion Control System is op­
erating properly, t he exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. Th is depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or fi lli ng the tank
wi th lead-free super g rade gasoline.

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
