On-Board Diagnostic
system (OBD)
System indicator light (MIL)
The system indicator light (M IL)
¢4 in the instru­
ment cluster is part of the On Board Diagnostic
System (080 II).
The warning/indicator light turns on when the ig­ nition is switched on and turns off once the en­
gine is started and is running in id le at a stable
speed. This indicates that the MIL is functioning
correctly.
If the light doe s not turn off after starting th e
engine or turns on whi le driving, this may indi­
cate there is a malfunct ion in the engine. If the
26
indicator tu rns on, the cata lytic conve rter may be
damaged.
D rive with reduced engine performan ce (avoid
high speeds for extended per iods of t ime and/o r
fast acceleration) and have the ma lfunction cor ­
rected. See an authorized Audi dealer or author­
i zed Audi Service Facility .
The ind icator may turn on if the e lectro nic speed
li miter is faulty . For add itiona l information, refer
to
c::> page 130, Electronic speed limiter.
The MIL may a lso turn on if the fuel filler cap is
not clo sed corre ctly

Roof rack
Description and mounting locations
Additional cargo can be carried with a roof lug­
gage rack.
Fig. 69 Roof rack attachment points (w it h out roof rails)
Fig. 70 A3 Sportback w ith roof rail: Roof rack attac hment
points
" Always read and follow the instructions prov id­
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 followi ng:
- Only use roof racks approved for your vehicle.
These approved roof racks are the basis for a
complete roof rack system. Additional attach­
ments o r carrier systems are needed to trans­
po rt luggage and sports equ ipment. We recom­
mend using roof racks from the Aud i orig inal
accessor ies program.
- When ins tall ing the roof rack, make sure it is
o nly mounted on the designated locations on
the roof
r=;, fig. 69.
- We recommend that you keep the installation
inst ruct ions for your roof rac k system togethe r
with yo ur Ow ner's li teratu re in the vehicle.
68
When should th e roof rack be removed?
- Before goi ng through an automatic car wash (it
is best to ask the car wash operator for advice).
- When not in use, to reduce fuel consumpt ion,
w ind no ise and to g uard aga inst 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.
- On ly mount the roof rack on the designated
locations on the roof
r=;, fig. 69.
- The roof rack system must be insta lled ex­
actly according to the i nstr uctions provided.
- When drivi ng with a roof rack system,
changes to the center of gravity and wind
resistance can change the vehicle handling
and lead to a co llision. Always adapt yo ur
driving and your speed to the current condi­
tions.
(D Note
- Your vehicle warranty does not cove r any
damages to the vehicle caused by using roof
racks or mounting structures not approved
by Audi for yo ur vehicle . The same applies to
damage resulting from incorrect roof rack
ins tallation.
- Always check the roof rack mountings and hardwa re before each trip and du ring a t rip
to ma ke sure eve ry t hing is securely tight­
ened. If necessa ry, retighte n the mountings
and che ck the entire sys tem from time to
t ime.
- After mou nting a roof rac k system, o r when
yo u transport ob jects on the roof o f your
ve­
hicle, the he ight of the vehicle is natura lly
increased. Be careful when driving under
low bridges or in parking garages for exam­
ple. This could cause damage to the load
and
even the vehicle itself.
- Make sure the open rear lid and the sun­
roof" do not come into contact w it h the roof
rack.

,....,
N
0 > co ,...., Loading the roof rack
Always distribute loads evenly. Make sure any­
thing on the roof rack is securely tied down .
11-Always distribute the loads on the roof rack
evenly .
11-Always attach items to the roof rack securely
before you drive off.
The maximum permiss ible roof weight is
165 lb
( 7 5 kg ). The roof weight is the total of the
weight of the roof rack, the attachments and the
cargo you are carrying. You must also not exceed
the maximum load weight fo r th e roof rac k you
are using.
When us ing a roof rack system wh ich has a lower
l oad carry ing capacity, you must not use up the
to ta l maximum permissible load car rying capaci­
ty specified above. Instead, you s hou ld load the
r oof rack system only to the maximum capac ity
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 fa il during
hard braking or in a collision and cause seri­
ous personal injury.
- Make sure the roof rack is installed exactly
as spec ified above
c> page 68.
- Always use su itab le mounting straps for se­
curing items to the roof rack to help prevent
items from shifting or fly ing forward .
- Items on the roof rack must always be se­
curely mounted.
- The use of a roof rack can negatively affect
the way a vehicle handles. Cargo that is
large, heavy, bulky, long or flat will have a
greate r negative influence on the vehicle's
aerodynamics, cente r of g ravity and ove rall
hand lin g. A lways d rive slowly, avoid sudden
bra king and mane uvers when transpo rting
cargo on the roof of you r vehicle .
- Never exceed the maxim um permissible
load carrying cap aci ty of the roof of you r ve­
hicle, the permissib le ax le weigh ts and the
permissible total weight of your vehicle
c> page 301, Weights.

Seat s and sto rage
{® 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.

Warm and cold
Warm and cold Climate control system
Description
Different systems could be installed.
- manual climate control system* or
- automatic climate control system*
- Plug-in hybrid drive* climate control
¢page 122
The climate control system* cools and removes
humidity from the air in the vehicle interior. It is
the most effective when the windows and panor­
ama sunroof* are closed.
If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling process. For this reason, the
windows and panorama sunroof can be opened from the outside .
¢ page 43, Convenience open­
ing/closing
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air .
Key recognition
You can store various settings for the manual and
automatic
climate control system* and assign
them to the key being used.
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog.
- Become familiar as quickly as possible with
the correct use and function of the cl imate
control system, especially with the defrost­
ing and defogg ing function.
- When the temperature is below freezing,
only use the windshield washer system after
70
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­
ty.
Cl) Note
- If you suspect that the climate control sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools. See an authorized Aud i dealer
or authorized Aud i Service Facility .
@ For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter the
air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system* can
dr ip and form a puddle of water unde r the
vehicle. This is norma l and does not mean
there is a leak.
- Th e energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy supply has been
restored.
- The f lows through the vents under the rear
window. Make sure the openings are not
covered when placing clothing on the lug­
gage compartment cover .
