Warm and cold Climate control
Description
The climate control system warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It is the most effect ive when the windows and
panoramic sliding sunroo f* are closed . If
there is a build-up of heat inside the vehicle,
venti lation can help to speed up the cooling
process.
I n all heating mode f unctions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensation from the cooling system can
drip and form a puddle of water under the ve­hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The po llutant filte r removes po llutants s uch
as dust and pollen from the air.
The air pollutants filte r must be changed at
the in tervals specified in you r Wa rranty
&
Main tenance book let, so tha t the air condi­
tioner can properly work.
I f you drive you r vehicle in an area with h igh
a ir po llution, the fi lter may need to be
ch anged more freq uent ly than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authorized A udi Service Ad­
visor for advice .

quire specia l techni cal know ledge and
speci al tools. Contact an autho rized Aud i
dealer fo r ass istance.
@ For the sake of the environment
B y reduci ng the amou nt of f uel you use,
you also red uce the amount of pollutan ts
emitted in to the air.
(D Tips
- Keep the air intake s lots ( in fro nt of the
w indshield) free from ice, snow and de­
br is in order to maintai n the proper f unc ­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporar i Ly . These systems
are available again as soon as the energy
balance has been restored.
- The air flowing out of the vents and
throughout the vehicle's entire interior is
discharged at the rear of the ve hicle.
Make sure that the outlet slots are not
covered by clothing, etc.

Hybrid
Hybrid drive
Introduction
Applies to vehicles: with hybri d dr ive
General information
The hybrid drive is a combined drive concept
that automat ically switches between combus­
tion engine and e lectric dr ive types or com­
b ines them.
All work on h igh voltage systems is intended
only for high voltage technicians and may only
be performed by authorized service facilities
in accordance with Audi regulations.
The high voltage system is composed of the
following h igh voltage components : the high
voltage battery, the power electronics, the
e lectric motor, the high voltage A/C compres­
sor and the orange high voltage wiring.
High voltage battery
The high voltage battery is located in the lug­
gage compartment underneath the cargo
floor. You do not need to perform any mainte­
nance work on the high voltage battery . Addi ­
tional information about the high voltage bat­
tery can be found under
r=> page 105.
The high voltage battery serv ice plug is a lso
found underneath an orange cover under the
cargo floor. The service plug is provided on ly
for use by service personnel and must not be
removed by others who are not trained to use
it .
A WARNING
The voltage in the high voltage system is
life-threatening. Touching a damaged high
voltage component can result in a fatal
electric shock. The components in the high
voltage system are marked with a warn ing
label which warns against the high volt­
age.
- Never perform work on orange high volt­
age cables or on high voltage compo­
nents . On ly authorized repair facilities
Hybr id 97
that are certified may perform work on
the high voltage system.
- Never open or remove the service plug
cover in the center of the cargo floor.
- Never damage, alter or remove the or­
ange high voltage cable or disconnect it
from the high voltage system.
- Audi regulations must be followed dur­
ing all work performed on the high volt­
age system and high voltage compo­ nents.
A WARNING
While in electric drive mode, the vehicle
produces considerably less idling, driving
and operat ing noise than when the com­
bustion engine is running. This may make
it difficult or impossible for others such as
pedestrians and children to hear and no­
tice the vehicle when it is in electrical drive
mode. This can lead to co llisions and inju­
ries, for examp le in low traffic areas, when
maneuvering or when driving in reverse.
A WARNING
-
-
Never leave the vehicle unattended while
in the drive ready mode. The vehicle could
begin moving if the accelerator pedal is
pressed, even if the combustion engine is
switched off . This may cause collisions and
severe or fata l injuries. When the vehicle
enters drive ready mode, the status mes­
sage
ybr I P cl, appears briefly in the in­
strument cluster disp lay and the needle in
the power meter points to
READY
r=> page98 .
-When exiting the vehicle, make sure the
selector lever is in the P position, the ig­
nition is switched off and the hybrid sys­
tem is deactivated .
(D Note
-The high voltage system can be damaged
if the vehicle underbody comes into con­
tact with the ground . Immediate ly drive
your vehicle to an authorized repair fa­ cility and have it inspected.

108 Audi adaptive cruise control and braking guard
confirmed by the video camera, an acute
collision warning.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construc tion
zones. This prevents the vehicle from ac­
celerating to the set speed when in these
situations.
- Th e adaptive cruise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation.
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cr uise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road or on­
coming objects .
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
ano ther vehicle too closely . Always re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch adaptive cruise control off when it
is not being used.
QJ Note
The sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and underbody.
That could affect the adaptive
cruise control system and braking guard. Have yo ur authorized Aud i dea ler or a u­
thorized Audi Service Facility check their
function.
In curves
Applies to vehicles: with Audi adaptive cruise contro l
Fig. 115 Examp le: driv ing into a curve
When driving into a curve ¢fig . 115 and out
of a curve, the adaptive cruise control may re­
act to a vehicle in the next lane and app ly the
brakes. You can override or prevent the brak­
ing by pressing the accelerator pedal briefly.
' Stationary objects
Applies to vehicles: with Aud i adapt ive cru ise contro l
Fig. 116 Example: object changing lanes and station­
a ry object
T he adaptive cru ise control system only reacts
to objects that are moving or that the system
has a lready detected as moving. For examp le,
if a vehi cle@ , which has al ready been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
® is located in front of that vehicle, the sys­
tem will not react to the stat ionary veh icle.

@ Tips
-Side assist is not active whi le you are
making the adjustment.
- Your settings are automatically stored
and assigned to the remote control key
being used.

Safety belts 155
Improperly worn safety belts
I ncorrectly positioned safety belts can cause
severe injuries .
Wearing safety belts improperly can cause se­
rious injury or death. Safety belts can only
work when they are correctly positioned on
the body . Improper seat ing pos itions reduce
the effectiveness of safety be lts and will even
i ncrease the risk of injury and death by mov­
ing the safety be lt to crit ica l areas o f the
body. Improper seating positions also in ­
crease the risk of serious injury and death
when an airbag dep loys and strikes an occu­
pant who is not in the correct seating posi­
tion. A driver is responsible for the safety of
all vehicle occupants and especially for ch il­
dren . Therefore:
.. Never permit anyone to assume an incorrect
sitt ing position in the vehicle while traveling
¢ &,. .
A WARNING
Improperly worn safety belts increase the
risk of serious persona l injury and death
whenever a ve hicle is being used.
- Always make s ure that all vehicle occu­
pa nts are co rrectly restrained and stay in
a co rrec t seating position whenever the
veh icle is being used .

Safety belt preten­
sioners
How safety belt pretensioners work
In front , side and rear -end collisions above a
particular severity and in a rollover, safety belts are tensioned automatically .
The safety belts are equipped with safety belt
pretensioners . The system is activated by sen­
sors in front, side and rear-end co llisions of
great seve rity and in a rollover . This tightens
the belt and t akes up belt slack¢.&.

Note
Never let the be lt remain over a rea r seat­
back that has been folded forward.
@ Tips
The safety be lt pretensioner can only be
activated once .
- In mino r frontal and side collisions, in
rear -end collisions and in accidents in­
vo lving very little impact force, the safe ­
ty belt pretensioner are not activated.
- When the safety be lt pretensioners are
activated, a fine dust is released . This is
norma l and is not caused by a f ire in the
vehicle.
- The relevant safety requirements must
be observed when the vehicle or compo­
nents of the system are scrapped. An au­
thorized Aud i dealer or qua lified work­
shop is fam il iar with these regulations
and will be p leased to pass on the infor­
mation to you.
- Be sure to observe a ll safety, environ­
mental and othe r regulations if the vehi­
cle or indiv id ual pa rts of the system, par­
ticularly the sa fe ty belt or airbag, a re to
be disposed. We recommend you have
your a uthorized Audi dea ler perform this
serv ice for you.
Service and disposal of safety belt
pretensioner
The safety belt pretensioners are parts of the
safety be lts on your Audi . Installing, r emov­
ing, servicing or repa iring of belt prete nsion­
e rs can damage the safety be lt system and
prevent it from working correct ly in a colli­
sion.
There are some important things you have to know to make sure that the effect iveness of
the system will not be impaired and that dis- ca
rded components do not cause inju ry or pol ­
l u te the environment.
A WARNING
-Improper care, serv ic ing and repair proce-
d ures can increase the risk of personal in­
jury and death by prevent ing a safety belt
p retensioner from activating when needed
or activating it unexpectedly:
- The belt pretensioner system can be act i­
vated only once. If belt pretensioners have been activated, the system must be
replaced.
- Never repair, adjust, or change any parts
of the safety be lt system.
- Safety belt systems including safety belt pretens ioners cannot be repaired. Spe­
cial procedures are required for removal,
installation and disposa l of th is system.
- For any wo rk on the safety belt system,
we strong ly recommend that you see
your author ized Audi dealer or qualified
technician who has an Audi approved re­
pair manua l, training and special equip ­
ment necessa ry .

the system will not be impaired and that dis­
carded components do not cause injury or pol­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi.
Airbag system 171
-Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed, it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­ placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a
pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer - risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.

dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi, lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
unit. Some suspension changes can, for exam­ ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made . Other kinds of
changes may reduce the force levels meas­
ured by the sensors and prevent the airbag
from deploying when it should.
The sensors in the safety belt buckle for the
driver and front passenger seat tell the elec­
tronic control module if the safety belt is
latched or not.
If the safety belt is being used,
the front airbag will deploy at a slightly high­
er rate of vehicle deceleration than if the safe­
ty belt is not being used. Therefore, in a par­
ticular collision, it is possible that an airbag
will not deploy at a seating position where the
safety belt is being used but will inflate at the
position where the safety belt is not being
used. It is important that nothing interfere
with the safety belt buckles so that the sen­
sors can send the correct information about
safety belt use to the electronic control unit.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire-rim combina­
tions can change Advanced Airbag per­
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance characteristics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
A WARNING
= -
Items stored between the safety belt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the electronic con­
trol module and prevent the Advanced Air­
bag System from working properly.
- Always make sure that nothing can inter­
fere with the safety belt buckles and that
they are not obstructed.
Side airbags
Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 170 S ide a irbag location in the driver's seat
The side airbags are located in the sides of the
front seat backrests¢
fig. 170 and the rear
backrest* facing the doors. They are identified
by the word "AIRBAG".
The side airbag system basically consists of:
-the electronic control module and external
side impact sensors
- the two airbags located in the sides of the
front backrests and the two airbags* located
in the rear backrest
- the airbag warning light in the instrument
cluster.
The airbag system is monitored electronically
to make certain that it is functioning properly ..,.

206 Driving and en vir onm ent
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 228,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 238, Adding engine oil~-
., Never try to push- or tow -start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt­
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 238.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis­
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not turn off the ignition while the ve ­
hicle is moving.
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec­
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam ­
aged.
T his is espe cially true for ve hicles with low­
s lung chassis (spor ts chassis)* and fully load­
ed vehicles .

208 Driving and environment
would go unheeded. Extended idling also
produces heat, which could 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 serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumption.
Check your oil each time you fill your tank.
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain mileage has been driven .
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly
assess oil consumption .
This also applies to fuel consumption and en­
gine output .
{Q) Note
-Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could 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 shields, switches, ignition wires,
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 driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effectively.
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile , fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km),
the engine is at its proper operating tempera­
ture and fuel economy has reached a normal level. So you can see that you should avoid
short trips whenever possible .
T he
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer .
