Warm and cold Climate control system
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 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 unde r the vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filte r removes pollutants such as
dust and pollen from the ai r.
The air pollutants filter must be changed at the
intervals specified in your Warranty & Mainte­
nance booklet, so that the a ir condit ioner can
properly work.
If you drive your vehicle in an area with high air
pollution, the filter may need to be changed
more frequently than spec ified in your Audi Wa r­
ranty
& Maintenance booklet. If in doubt, ask
your authorized Audi Service Adv isor for advice.
Key coded settings
The climate control settings are automat ically
stored and assigned to the remote control key
that is in use.
_&. WARNING
Reduced visibility is dangerous and can cause
accidents .
- For safe dr iv ing it is very important that all
windows be free of ice, snow and condensa­
tion .
Warm and cold
-Comp letely familiarize yourse lf with the
proper use and funct ion of the heating and
ventilation system and especially how to de­
fog and defrost the windows.
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshie ld first, using the heat­
ing and vent ilation system. The washer solu­
tion may freeze on the windsh ield and re­
duce visibility.
(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 qualified dealership.
- Repairs to the Audi air conditioner require
special techn ical knowledge and spec ial
tools. Contact an authorized Aud i dealer for
assistance.
@ For the sake of the environment
By reducing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
- Keep the air intake slots (in front of the
w indshield) free from ice, snow and debris
in order to main tain the proper function of
the climate control system.
- T he energy management system may switch
the seat heating * or rear window defroster
off temporarily. These systems are avai lab le
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of cloth ing on
the luggage compartment cover, ensure
that the openings are not covered.

Audi adapt ive crui se cont rol and bra king gu ard
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing) . Us ing the system under these condi­
tions co uld resu lt in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from acce lerating to
the set speed when in these situations.
- T he adapt ive cruise con trol system w ill not
brake by itself if you put your foot on the ac­
celerator pedal. Do ing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have
limited function .
- The adaptive cruise control system and brak­
ing guard do not react to people, anima ls,
objects cross ing the road or oncoming ob­
jects.
- The function of the radar sensor can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safely. The adap­
t ive cr uise control cannot s low or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remembe r that the
au tom atic b ra ki ng function cannot bring the
vehicle to a su dden or emergency stop un­
der these conditions.
- T o prevent unin tended operation, always
swit ch ACC
off when i t is not be ing used .
(D 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
cru ise cont ro l system and braking guard. Have
"' "' your authorized A udi dealer or authorized 0::

Fig. 91 Examp le : d ri ving into a curve
When driving into a curve c:> fig. 91 and out of a
curve, the adaptive cruise control may react to a
vehicle in the next lane and apply the brakes . You
can override or prevent the braking by press ing
the accelerator peda l briefly.
Stationary objects
Appl ies to vehicles : w ith Audi adaptive cruise control
Fig. 92 Example: object chang ing lanes a nd stationary ob·
ject
T he adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving. For example, if a ve­
hicle @, which has already been detected by the
adaptive cruise control, turns or changes lanes
and another stationary veh icle @ is located in
front of that ve hicle, the system will not react to
t h e stat ionary vehicle.

- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your
blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- in poor weather conditions such as heavy
rain, snow or heavy mist.
- on very wide lanes, in tight curves or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor

Safe ty belt s
& WARNING
Improperly worn safety belts increase the risk
of serious personal injury and death whenever
a vehicle is being used.
- Always make sure that all vehicle occupants
are correctly restrained and stay in a correct
seat ing pos ition whenever the veh icle is be­
ing used .
- Always read and heed all WARNINGS and
other important information
¢ page 122 .
Belt tensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a
particular sev erity, safety belts are tensioned au­
tomatically.
The safety be lts are equipped with safety be lt
p retens ioners. The system is activated by sensors
in front, side and rear-end co llisions of great se ­
verity. This tightens the be lt and takes up belt
slack
¢ .&. in Service and disposal of safety belt
pretensioner on page 126.
Taking up the slack
helps to reduce forward occupant movement dur­
ing a collision .
(D Note
Never let the be lt remain over a rear seatback
that has been folded forward.
(D Tips
The safety be lt pretensioner can only be acti­
vated once.
- In minor frontal and side collisions, in rear­
end collisions, in a rollover and in accidents
i nvo lv ing very little impact force, the safety
belt pretensioner are not act ivated.
- In the case of a side crash, the safety belt pretensioners w ill act ivate on the driver's or
front passenger's sides only, depending on which side of the vehicle the crash occurs.
- When the safety belt pretensioners are acti­
vated, a fine dust is released. This is normal
and is not caused by a fire in the vehicle.
- The relevant safety requirements must be
observed when the vehicle or components
126
of the system are sc rapped . An authorized
Audi dealer or qualified workshop is familiar
with these regulations and will be pleased
to pass on the information to you.
- Be sure to observe all safety, environmental
and other regu lations if the vehicle or indi­
vidual parts of the system, particularly the
safety belt or airbag, are to be disposed. We recommend you have your author ized Audi
dealer perform this service for you .
Service and disposal of safety belt preten­
sioner
'
The safety belt pretensioners are parts of the
safety belts on your Audi. Insta lling, removing,
servicing or repairing of be lt pretensioners can
damage the safety belt system and prevent it
from work ing correctly in a collision.
There are some important t hings you have to
know to make sure that the effectiveness of the
system will not be impaired and that discarded
componen ts do not cause injury or pollute the
environment .
& WARNING
Improper care, serv ic ing and repair proce­
dures can increase the risk of personal injury
a nd death by p reventing a safety be lt preten ­
sione r from activating when needed or acti­
vating it unexpected ly:
- The belt pretensione r system can be act ivat­
ed only once. If belt pretensioners have been activated, the system m ust be re­
placed .
- Never repair, adjus t, or change any parts of
the sa fety belt system.
- Safety belt systems including safety belt
pretens ioners cannot be repaired. Spec ial
procedures are req uired for remova l, instal­
lation and disposa l of this system .
- For any wo rk on the safety be lt system, we
strongly recommend that yo u see your au­
thorized Audi dealer or qualified technician
who has an Audi approved repair manual,
train ing and spec ial equ ipment necessary .

Other things that can affect Advanced
Airbag performance
Changing the vehicle 's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For example, using t ire-rim
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspension,
including the spr ings, suspension s truts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control un it. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in c rashes in which it wo uld not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and preve nt the airbag from deploy­
i n g when i t should .
A WARNING
Changing the vehicle's s uspension including
use of unapproved ti re -rim comb inations can
change Advanced A irbag pe rformance and in ­
crease t he risk of serious persona l injury in a
crash.
- Never install suspension components that do not have the same performance charac­
teristics as the components or iginally insta l­
led on your veh icle.
- Never use tire-rim combinations that have
not been approved by Audi.
142
A WARNING
Items stored between t he safety be lt b uckle
and the center console can cause the sensors i n the buckle to send the wrong informat ion
to the electronic control module a nd prevent
the Adva nced Airbag System from wor king
properly.
- Always ma ke sure that nothing can interfere
w it h the safe ty belt bu ckles an d that they
are no t obstr ucted.
Knee airbags

-Have your veh icle maintained properly and
in accordance with the service recommen­
dations in your Warranty
& Maintenance
book let.
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel being used . Using a differ­
ent brand of fuel may help, or filling the tank
w ith lead-free super grade gasoline.
Shutting down vehicle
If you wou ld like your vehicle to remain inopera­
tive for a longer period of time, contact an Audi
or other specialized dealer. T hey can advise you
on necessary precautions e.g. corrosion preven­
tion, maintenance and storage. Pay attention to
additional information concerning the battery. Refer to
c:;, page 196.
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.
Fu el economy, environmental impact , and wear
on your engine, brakes and tires largely depend
on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fue l
consumption by 10-15 percent. This sect ion will
give you some tips on how you can help the envi­
ronment and your pocketbook .
Driving and the environment
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
will vary depending upon vehicle load and
speed, road and weather conditions, tr ip
l ength, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler ­
ating .
.. Avoid unnecessary accelerating and braking .
Vehicles 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
erate less. Let the veh icle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red.
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 fue l consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumpt ion, exhaust emiss ions and engine
noise increase disproportionately at high speeds.
If you drive at approximate ly three quarters of
top speed, fue l consump tion will be reduced by
one half. Never drive faster than the posted
speed l imit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
.. Shut the eng ine off when you are not driving
the vehicle.
.. Do not warm up the vehicle by letting the en-
gine run at idle .
ll>
179

Driving and th e environment
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rai lroad
crossings, or at traff ic lights that have long waits
on red. Turning the eng ine off for just 30-40 sec­
onds saves more fuel than is burned starting the
engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and nox ious em issions are especially h igh when
the engine is warm ing up. So you should dr ive
away as soon as you start the engine and avoid running at high rpms while the engine is still
warming up.
{[) Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended id ling a lso produces
heat, wh ich co uld resu lt in overheating or ot h­
er damage to the vehicle or other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
~ Have you r vehicle se rv iced at regular i nte rva ls.
By having your vehicle regularly serviced by an
author ized Audi dealer helps to ensure that it
r u ns p roperly and economically. The condition of
your veh icle not only affe cts its safety and ability
to hold its va lue, i t also affects
fue l con sump ­
tion.
Ch eck your oil each tim e 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 en­
g ine to reach its lowest value after a certain mile­
age has been driven.
You must drive yo ur vehicle about 3,000 miles
(5,000 ki lometers) before you can properly as­
sess o il consumption .
This a lso applies to fuel consumption and engine
output .
180
(D Note
-Have your veh icle ma intained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and cou ld 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, sw itches, ignit ion wires,
valves, which a re des igned to p rotect your
vehicle's Emission Control System and other
impo rtant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
~ Tr y to avoid dr iv ing sho rt distances w ith a co ld
eng ine .
The eng ine and cata lytic converter have to reach
their opt imal
op erat ing temperature to reduce
fuel consumpt io n and noxious em issions effec­
tive ly.
Just after starting, a co ld eng ine in a mid -s ize car
o nly achieves a fuel economy of 6-8 m iles per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy climbs to 12 mpg ( 20 l/100
k m). After about
2.5 mi les ( 4 km) , the eng ine is
at i ts p roper operating tempera ture and fuel
economy has reached a normal level. So you can
see that yo u should avo id short trips whenever
poss ib le.
The
outside temperature is also cr itical in th is re­
gard. Your car cons umes more fuel in the winter
than in the summer.
