A WARNING
-The rain sensor is only intended to assist
the driver. The driver is still responsible
for manually switching the w ipers on ac­
cording to the v is ibility conditions.
- The windshield may not be treated w ith
water-repe lling windshie ld coat ing
agents. Unfavorable conditions, such as
wetness, darkness or low sun, can result in increased glare. W iper blade chatter is
also possible.
- Properly functioning windshie ld w iper
blades are required for a clear view and
sa fe driving

front windshield wiper blades.
0 Note
- In case of frost, make sure the wind­ shield wiper blades are not frozen to the
windshield. Sw itching on the windshield
wipers when the blades are frozen to the
windshield can damage the wiper blades.
- Prior to using a car wash, the windshield
wiper system must be switched off (lever
in position 0). This prevents unintention­
al sw itching on and damage to the wind­
shield wiper system.
- Do not use the wipers to remove ice from
the windows. Using windshield wipers as
ice scrapers destroys the wiper blades.
{D Tips
- The windshield wipers switch off when
the ignition is turned off. You can acti­
vate the w indshield wipe rs after the igni­
tion is switched back on by moving the
windsh ield wiper leve r to any pos ition.
- Worn or dirty windsh ield wiper blades
result in streaking. Th is can affect the
rain sensor function. Check your w ind­
s h ield wiper blades regularly.
- The washer fluid nozzles in the w ind­
shield washer system are heated* at low
temperatures when the ignit ion is on.
- When stopping temporarily, such as at a
traff ic light, the speed of the windsh ield wipers automatically reduces by one
lev­
el.
- In vehicles with an MMI, you can switch
the rain sensor or off in the

veh icles behind you when changing lanes -
accident risk!
@ Note
- For vehicles with power folding exterior
mirrors*: If the m irror housing was
moved by outside forces (such as an im­
pact when maneuvering), you must use
the power folding function to fold the mirro r all the way out. You will hear a
l oud noise when the m irrors are latched
back in place. The mir ror housi ng must
not be moved back into place by hand
because this would affect the mirror
mechan ism.
- Applies to vehicles witho ut power fold­
i ng exter ior mirrors: If the mirror hous­
ing was moved by outside forces (suc h as
in impact during maneuvering), you
must move the m irror housing back into
place by hand.
- If you wash the vehicle in an automatic
car wash, yo u m ust fold the e xterior m ir­
r o rs in to reduce the risk of damage to
the m irrors. Never fold power fo ld ing ex-

General information
Important information
A WARNING
Refer to the chapter Driving Safely
¢ page 126, Driving safety for important
information, tips, suggestions and warn­
ings that you should read and follow for
your own safety and the safety of your pas­ sengers.
The safety belts and the airbag system con
only provide maximum protection if the front
seats ore correctly adjusted.
There are various ways of adjusting the front
seats to provide safe and comfortable support
for the driver and the front passenger. Adjust
your seat properly so that :
- you can easily and quick ly reach all the
switches and controls in the instrument
panel
- your body is properly supported thus reduc­
ing physical stress and fatigue
- the safety be lts and airbag system can offer
maximum protection
¢ page 146.
In the following sections, you will see exactly
how you can best adjust your seats .
There are special regulations and instructions
for installing a child seat on the front pas­
senger's seat. Always follow the information
regarding chi ld safety provided in
¢ page 169, Child Safety.
A WARNING
Incorrect seating position of the driver and
all other passengers can result in serious
personal injury.
- Always keep your feet on the floor when
the vehicle is in motion -never put your
feet on top of the instrument panel, out
of the window or on top of the seat cush­ ion. This applies especially to the passen-
Seats and storage 59
gers. If your seating position is incorrect,
you increase the risk of injury in the case
of sudden braking or an accident. If the
airbag inflates and the seating position is incorrect, this could result in pe rsonal
injury or even death.
- It is important for both the driver and
front passenger to keep a distance of at
least 10 inches (25 cm) between them­
selves and the steering wheel and/or in­
strument panel. If you're sitting any
closer than this, the airbag system can­
not protect you properly. In addition, the
front seats and head restraints must be
adjusted to your body height so that they
can give you maximum protect ion.
- Always try to keep as much distance as
possible between yourself and the steer­
ing wheel or instrument panel.
- Do not adjust the driver's or front pas­
senger's seat whi le the vehicle is moving.
Your seat may move unexpectedly, caus­
ing sudden loss of veh icle control and
personal injury. If you adjust your seat
while the veh icle is moving, you are out
of posit ion.
Driver's seat
The correct seat position is important for safe
and relaxed driving .
We recommend that you adjust the dr iver's
seat in the follow ing manner:
"" Adjust the seat in fore and aft direction so
that you can easily push the pedals to the
floor wh ile keeping your knees slightly bent
¢ &, on page 59.
"" Adjust the backrest so that when you sit
w ith your back against the backrest, you can
still hold the top of the steering wheel.
""For adjustab le head restra ints: adjust the
head restraint so the uppe r edge is as even
as possible with the top of your head. If that
is not possible , try to adjust the head re­
straint so that it is as close to this position ..,_

70 Warm and cold
Warm and cold Climate control system
Description
Different systems could be installed.
- manual climate control system* or
- automatic climate control system*
The
climate control system* cools and re­
moves humidity from the air in the vehicle in­
terior. It is the most effective when the win­
dows and power top are closed. If there is a
build-up of heat inside the vehicle, ventila tion
can help to speed up the cooling process. Be­
cause of this, the windows can be opened
from outside .
~ page 39, 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 a ll windows free
of ice, snow and fog.
- Become familiar as quickly as possible
with the correct use and function of the
climate control system, especially with
the defrosting and defogging function .
- When the temperature is below freezing,
only use the windsh ield washer system
after the w indshield has been warmed by the cl
imate control system . The washer
fluid could freeze on the windshield and
impair visibility.
(D Note
- If you suspect that the climate control
system 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 sys­
tem require special technical knowledge
and special tools. See an authorized Audi
dealer or authorized Audi Serv ice 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
w indows from fogging over, the air in­
take in front of the windshield must be
free of ice, snow or leaves.
- Condensation from the cooling system*
can drip and form a puddle of water un­
der the vehicle. This is normal and does
not mean there is a leak.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporari Ly. These systems
are available again as soon as the energy
balance has been restored.
- The flows through the vents under the
rear window. Make sure the openings are
not covered when placing clothing on the
luggage compartment cover.

when road cond itions are poor (such as
ice, fog, gravel, heavy rain and hydro­
plan ing) -you could have an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway
e xits or in construction zones.
- Please note that unconsc iously "resting"
your foot on the accelerator pedal p re­
vents t he cr uise control from b raking.
This is due to the control system be ing
over ridden by the dr iver's acceleration .

Audi adaptive cruise control
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system is a com bi·
nation of speed and distance regulation. It as ­
sists the dr iver by both regulat ing the speed
and maintain ing a distance to the object
ahead, within the abilities of the system. If
the system detects an object, adaptive cru ise
control can brake and acce le rate your ve hicle.
This makes driving more comfortable both on l ong stretches of highway and in stop-and -go
traffic.

-The system has a limited ability to detect
objects that are a short d istance ahead, off
to the side of your vehicle or moving into
your lane.
- Objects that are difficult to detect such as
motorcycles, veh icles with high ground
clearance or an overhanging load are detect­
ed late or not detected at all.

88 Audi adaptive cruise control
- When approaching stationary objects
such as stopped traff ic, adaptive cruise
control will not respond and pre sense
front will have limited function.
- The adaptive cruise control system and
pre sense front do not react to people,
animals, objects cross ing the road or on­
coming objects.
- The function of the radar sensors can be
affected by reflective objects such as
guard rai ls, the entrance to a tunnel,
heavy rain or ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function ca nnot bring the veh icle to a
sudden or emergency stop under these
condit ions.
- To prevent unintended operation, always
switch ACC off when it 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 . The adaptive cruise contro l
and pre sense front may become impaired
as a result . Have an authorized Audi dealer
or author ized Audi Service Facility check
their function.
