Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof * are closed. If there is a bui ld-up of heat
insid e the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode f unctions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reach ed a suffici ent tem­
perature .
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y recognit ion

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
contro l system, especially with the defrost­
ing and defogg ing function.
- When the temperat ure is below freezing,
only use the windsh ield washer system after
60
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshie ld and impair visibi li­
ty .
Cl) Note
-If you suspect that the cl imate contro l sys­
tem is damaged, switch the system
off to
prevent further damage and have it checked
by an authorized Aud i dealer or authorized
Audi Service Facility .
- Repa irs to the Aud i climate control system
requ ire special technical knowledge and
special tools . See an authorized Aud i dea le r
or autho rized Aud i Service Faci lity .
@ For the sake of the environment
- To save fuel, turn off cooling mode by press ­
ing the
IAJC I button. This w ill also reduce
em issions .
- In veh icles w ith a diesel engine, you ca n
switch the auto supplementary heater off in
the Infotainment system.
(D Tips
- To prevent interference with the heat ing
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.
- Conde nsation from the coo ling system can

General information
Breaking in
A new vehicle must be broken in, and the break­ i n distance should be 1,000 mi les (1,500 km). Do
no t drive at speeds th at wi ll exceed
2/3 of the
maximum permitted engine speed
(R PM ) for the
fi rst 600 mi les (1,000 km) , and avoid f ull accel­
eration d uring this period . You may gradua lly
start increas ing the
RPM and the speed between
600 m iles (1,000 km) and 1,000 m iles (1,500
km).
During the fi rst hou rs of use, the engine has a
h igher internal friction than later on when all
mov ing parts have settled into p lace with each
other.
How the ve hicle is driven d uring the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in per iod, part icu larly when running a cold
engine . This wi ll reduce eng ine wear and improve
the mi leage .
Do not dr ive at too
low of an engine speed (rpm).
Shift down if the engine stops r unning "smoot h­
ly". Extremely high eng ine s peeds are automati ­
cally reduced .
New tires
If yo ur vehicle is ru nning on new t ires, drive pa r­
t icularly c aref ul for the first 350 miles (5 00 kilo­
meters) after fi tting .
A WARNING
-
New tires tend to be s lippery and must also
be "broken-in". Be s ure to remember this dur­
ing the first 350 miles (500 kilometers).
Brake gently. Avo id following closely behind
other vehicles or other situations that might
require sudden, ha rd brak ing .
Avoid damaging the vehicle
When you are d riving on poo r roads, or over
curbs, steep ramps, etc., make ce rtain that low-
66
lying parts such as spo ilers and exha ust system
parts do not bottom o ut and get damaged.
This is es peci ally true for veh icles with low-s lu ng
c h ass is (sports chass is)* and fully loaded
vehicles .
Warming up/cooling down
Applies to: S models
By warming up/coo ling down t he engine careful ­
l y, you can he lp reduce unnecessary strain on
yo ur vehicle when dr iving in a sporty style.
The engine speed is limited when the engine is cold -the full engine o utp ut is not availab le.
When the engine is at operat ing temperat ure,
the engine speed limitation moves to a higher
RPM range. The t ires also only reach t he ir full
r oad holding capab ility once they have wa rmed
u p .
You r vehicle a lso has an after-run cooling fea­
ture . However, cooling down is still important.
The eng ine and the brakes as well as the e xhaust
system and the tra nsmission become very ho t
whe n driving in a spo rty style . B efo re you shut
t h e ve hicle off, yo u should cool down the vehicle
by drivi ng a few miles at low s peeds with ligh t ac­
ce lera tion.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, fo r example
on f looded roads:
- The water must not be any higher than the bot ­
tom of the vehicle body.
- Do not dr ive faster tha n wal king speed .
A WARNING
-
After driving thro ugh water or m ud, the effec­
tiveness o f the b rakes may be red uced due to
mo isture on the brake rotors and brake pads.
A few careful brake applications shou ld dry
off the brakes.
@ Note
- Vehicle components such as the engine,
transmiss ion, suspens ion or elect rical

Economical and environmentally-friendly
driving
The amount of fue l consumption, the e nviron­
men tal impact and the wear to the engine ,
b rakes and ti res depends mostly on your dr iving
s tyle. W it h an anticipatory a nd econom ic dr iv ing
style , fu el consumpt ion can be reduced by ap ­
p roxima te ly 10 -15% . The following tips will help
you conse rve the environment and you r money at
the same time .
Anticipatory driving
A vehicle uses the mos t fu el when a ccele ra ting.
W hen you drive wi th an tic ipa tion, you do not
n eed to brake as often and so yo u ac celerate less .
When possib le, let your vehicle coast w ith a
gear
engaged ,
for example, when you notice that the
next tra ffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumpt io n to ze ro (fuel shut-off dur ing decelera ­
tion) .
Shift efficiently
An effective way to save f uel is to upshift earlier .
Staying in a gear too long uses fue l unnecessari­
l y .
Press down o n the acce lerator peda l s lowly and
avoid "k ic k -down".
D riving
Avoid full acceleration
Yo u should rarely travel at the maxi mum vehicle
speed. High speeds cause a disproport ionate ly
high increase i n fue l cons umption, emissions and
t raffic noise. S lowe r driving saves fue l.
Reduce idling time
The Sta rt-Stop system* helps to red uce the idling
t ime a utoma tically. In veh icles w ithout the S ta rt­
Stop system *, i t is eff icient to sw itch the engine
off when stopped at railroad crossings and long
r ed lights. Stopping the engine for 30-40 sec­
onds a lready saves more fuel than the amo unt of
extra fue l needed to restart the engine.
It ta kes a very long time in id le to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm- up
phase. Therefore, you sho uld begin driving im­
med iate ly after starting the engine. Avoid h igh
RPMs wh ile doing this .
Have maintenance performed regularly
By having maintenance pe rformed regu larly on
your vehicle, you can help to reduce fuel co n­
sumption before you even start to drive. The
maintenance condition of your vehicle not o nly
affects traffic safe ty a nd long-term val ue but al­
so impa cts
fuel consumption . A poorly main­
t ai ned engi ne ca n lead t o fuel co nsump tion that
is 1 0% hig he r th an no rmal.
Avoid short trips
The eng ine and exhaust cleaning system must
r each their optima l
operating temperature to ef­
fec tively reduce consu mption a nd emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reac hes operat ing
temperat ure and cons umption normal izes on ly
af ter app roxima tely
2 .5 miles (4 km ).
Check the tire pressure
To save fuel, make sure the t ires are always in­
flated to the correct press ure
r:!;> page 220. The
fuel consumpt io n can increase by 5% if the pres ­
s ur e is on ly 0 .5 bar too low. Due to t he inc reased
r oll ing resistance, low tire p ressures w ill also .,..
67

Driving
lead to greater tire wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra
weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­ moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62- 7 5 mph (100-120 km/h) .
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting.
If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
CD Note
- Have your vehicle maintained 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
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,
68
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc.
