" N .... 0 0 :c ' Warm and cold Deluxe automatic
climate control
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 build-up of heat inside the vehicle, ventilation can help to speed
up the cooling process .
In all heating mode functions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem­
perature .
Pollut ant filt er
The po llutant filter removes pollutants such as
dust and pollen from the air.
Ke y r eco gnition
The climate control settings are a utomatically
stored and assigned to the remote control key
that is in use .
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 climate contro l system, especially with the defrost­
ing and defogging function.
- When the temperature is below freezing,
only use the windshield washer system after
Warm and c old
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­
ty .
@ Note
-If you suspect that the climate contro l sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Aud i Serv ice Facility.
- Repa irs to the Aud i climate control system
require special technical knowledge and
special tools . See an authorized Aud i dealer
or authorized Audi Serv ice Fac ility .
@ For the s ake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter the
a ir .
(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
fro nt of t he w indshie ld must be free of ice,
snow or leaves.
- Condensat ion from the coo ling system can
dr ip and form a pudd le of water under the
veh icle . T h is is no rma l and does not mean
there is a leak .
- Th e energy management system may tem­
porarily switch off certain functions, suc h as
the seat heating* or rear window defogger .
T hese systems are avai lable again as soon
as the energy supply has been restored.

-Avoid driving through sa lt water, because
this can cause corrosion .
Economical and environmentally-friendly
driving
The amount of fuel consumption, the env iron­
mental impact and the wear to the engine,
brakes and t ires depends mostly on your dr iv ing
style. W it h an anticipatory and economic dr iv ing
style , fu el consumption can be reduced by ap ­
p roximate ly 10 -15% . The following tips wi ll help
you conserve the environment and your money at the same time .
Anticipatory driving
A veh icle uses the most fuel when acce le rating.
When you dr ive with ant ic ipat io n, you do no t
need to brake as often and so you accelerate less .
When possib le, let your vehicle coast with a
gear
eng aged ,
for example, when you notice that the
next traffic 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 ion to zero (fuel shut -off during decelera­
tion) .
Shift efficientl y
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fue l unnecessari­
ly . Press down on the accelerator pedal slowly
and avoid "k ick-down" .
Avoid full accel eration
You shou ld rare ly trave l at the maximum vehicle
speed. High speeds cause a disproportionately h igh increase in fuel consumption, emissions and
traffic no ise . Slower driving saves fuel.
Reduce idlin g time
The Start/Stop system* he lps to reduce the idling
time automatically. In vehicles without the Start/
Stop system*, it is efficient to switch the eng ine
off when stopped at ra ilroad crossings and long
red l ights . Stopp ing the engine for 30 -40 sec­
onds already saves more fuel than the amount of
ext ra fuel needed to resta rt the eng ine.
74
It takes a ve ry 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 shou ld begin driving im­
med iate ly after starting the engine. Avoid high
RPMs while doing this .
Hav e maintenance perfo rmed regul arly
By having maintenance performed reg ularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not on ly
affects traffic safety and long-term value but al­
so impacts fuel consumpt ion. A poorly main­
ta ined engine can lead to fuel consumpt ion that
i s 10% hig he r th an no rma l.
Avoid short trip s
The engine and exhaust cleaning system must
reach their optimal operat ing temperature to ef­
fect ively reduce consumpt ion and emissions .
A cold engine uses a d isproportionately high
amount of fuel. The engine reaches operat ing
temperature and consumption normalizes only
after approximately 2 .5 m iles (4 km) .
Check the tire pressu re
To save fue l, make sure the t ires are always in­
flated to the correct pressure
¢ page 291. The
fuel consumpt ion can increase by 5% if the pres­
sure is only 0 .5 bar too low . Due to the increased
r oll ing resistance, low tire p ressures w ill also
l ead to greater tire wear and will affe ct driv ing
behav ior.
Drive w ith summer tires when poss ible because
t hi s can increase fue l economy by up to 10% .
Eliminate unnecessary weight
Since every pound of extra weight increases fuel
consumption, it pays to remove any unnecessary
weight.
A roof rack increases the w ind resistance on the
vehicle and shou ld be removed when it is not
needed. You will save approximately 12% of your
fuel when at speeds from 62-75 mph (100-120 km/ h).

This driver message appears fo r safety reasons if
the transmission has not been shifted to the P

Start/Stop system
Description
Applies to: vehicles with Start/Stop syste m
The Start/Stop system can help increase fuel
economy and reduce CO2 emissions.
In Start/Stop mode, the eng ine s hut s off auto­
matically when the vehicle is stopped, such as at
a traffic light . The ignition remains switched on
during this stop phase. The engine w ill restart
automat ically w hen needed.
The last Start/Stop system setting is restored
when the ignition is switched on.
Basic requirements for Start/Stop mode
- Th e driver's door must be closed.
- The driver's seat belt much be fastened.
- The hood must be closed .
- The vehicle must have dr iven faster than
2.5 mph (4 km/h) since the last t ime it stop ­
ped .
- A trailer must not be hitched to the vehicle .
A WARNING
-Never turn off the eng ine before the vehicle
has come to a complete stop . The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake. Because you

Automatic transmission
Introduction
The automat ic transmission is controlled e lec­
tron ica lly. Power is transferred using a torque
converter.
The transm ission shifts up or down automat ically
depending on wh ich drive program is selected.
When a
mod erate driving s tyle is used, the
transmission selects the most e conomical d riving
mode. The t ransm iss ion upsh ifts at a lower RPM
and downshifts at a highe r RPM to imp rove fuel
efficiency.
The transm ission switches to a spor ty mode after
a kick-down or when the driver uses a
sp o rt y
driving style
c haracterized by quick accelerator
pedal movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the dr iver can also select the gears
manually (tiptronic mode)

interfere w ith the function of pacemakers.
Always ma inta in a m inimum distance of
abou t 8 inches (20 cm) between the ce ll
phone antenna a nd the pacemake r.
- Do not carry the cell p hone i n a pocket di ­
rectly over the pacemaker when the phone
is switched on.
- Sw itch the cell phone off immediately if
you suspect it may be inte rfering with the
pacemaker.
- Do not use the voice recognition system
Q page 142 in emergencies because your
voice may change in stressful situations. It
may take longer to dial the number or the
system may not be able to dial it at all. Dial
the emergency numbe r manua lly.

there is a risk of an exp losion . These loca­
t ions are not always clearly mar ked. This
may include gas stations, fuel and chemic al
storage f acilit ies or tra nspo rt vehi cles, or lo­

chemicals or large quantities of dust parti­
cles (such as flour, sawd ust or metal) may
be present in the air. Th is also applies to all
other locations where you would normally
turn yo ur vehicle engine off.
