@) Tips
Some the equipment listed here is only instal-
led in certain models or is available as an op-
tion.
Indicator lights overview
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal-
functions. Some warning and indicator lights
turn on when you switch the ignition on and must
turn off when the drive system is switched on or
while driving.
With some indicator lights, messages may ap-
pear and warning signals may sound. The indica-
tor lights and messages may be covered by other
displays. To show them again, select the second
tab for messages with the multifunction steering
wheel > page 72.
Some indicator lights in the display can display in
several colors.
OMe ile Lins
If the A or A indicator light turns on, check the
message in the instrument cluster.

key with you, or unauthorized persons may
be able to enter the vehicle.
@ Tips
— Do not leave valuables unattended in the ve-
hicle. A locked vehicle is not a safe!
—The LED in the driver's door rail blinks when
you lock the vehicle. If the LED turns on for
approximately 30 seconds after locking,
there is a malfunction in the central locking
system. Have the problem corrected by an
authorized Audi dealer or authorized Audi
Service Facility.


BFV-0278



Fig. 11 Your vehicle key set
@ Remote or convenience key*
The convenience key* is a remote control key with
special functions > page 22 and > page 75.
You can unlock/lock your vehicle with the remote
control key. A mechanical key is integrated in the
remote control key > page 20.
@ Key tag with vehicle code*
The vehicle code* on the key tag can be rubbed
off. It does not have a function.
Replacing a key
If a key is lost, see an authorized Audi dealer or
authorized Audi Service Facility. Have this key de-
activated. It is important to bring all keys with
you. If a key is lost, you should report it to your
insurance company.
Number of keys
You can check the number of keys assigned to
your vehicle in the Infotainment system. To do

this, select the [MENU] button > Vehicle > left
control button > Service & checks > Vehicle in-
formation. This way, you can make sure that you
have all the keys when purchasing a used vehicle.

Electronic immobilizer
The immobilizer prevents unauthorized use of
the vehicle.
Under certain circumstances, the vehicle may not
be able to start if there is a remote control key
from a different vehicle manufacturer on the key
chain.
Data in the master key
When driving, service and maintenance-relevant
data is continuously stored in your remote con-
trol key. Your Audi service advisor can read out
this data and tell you about the work your vehicle
needs. This applies also to vehicles with a con-
venience key”.
Personal convenience settings
If two people use one vehicle, it is recommended
that each person always uses “their own” master
key. When the ignition is turned off or when the
vehicle is locked, personal convenience settings
for the following systems are stored and as-
signed to the remote master key.
— Climate control system
— Parking aid*
— Side assist*
— Drive select
The stored settings are automatically recalled
when you unlock the vehicle, open the doors or
turn on the ignition.

ZA\ WARNING
If you leave the vehicle, switch the ignition off
and take the vehicle key with you. This applies
particularly when children remain in the vehi-
cle. Otherwise the children could start the en-
gine or operate electrical equipment such as
power windows.
@) Note
Protect the remote control key against high
temperatures and direct sunlight.

Warm and cold

Warm and cold
Climate control system
The climate control system warms, cools, dehu-
midifies, and filters the air in the vehicle interior.
It functions most effectively when the windows
are closed. If there is a build-up of heat inside the
vehicle, ventilation can help to speed up the cool-
ing process.
The deluxe climate control system automatically
maintains a temperature once it has been set. In
all heating mode functions except defrost, the
blower only switches to a higher speed once the
coolant has reached a certain temperature.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.

ZA 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
control system, especially with the defrost-
ing and defogging function.
— When the temperature is below freezing,
only use the windshield washer system after
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 control sys-
tem 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 system
require special technical knowledge and
special tools. Have it inspected by an au-
thorized Audi dealer or a qualified electron-
ics store.
(@) For the sake of the environment
Reducing the amount of fuel used also re-
duces the amount of pollutants that enter the
air.
G) Tips
—To prevent interference with the heating
and cooling output and to reduce the risk of
the windows fogging over, the air intake 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 under the
vehicle. This is normal and does not mean
there is a leak.
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon
as the energy supply has been restored.
— The flows through the vents under the rear
window. Make sure the openings are not
covered when placing clothing on the lug-
gage compartment cover.

Deluxe automatic climate control


Fig. 78 Deluxe automatic climate control: controls
The functions can be switched on and off by
pressing the buttons or adjusted by turning the
knob. When the function is switched on, the LED
in the respective button or knob turns on.

AUTO] Automatic mode
Automatic mode maintains a constant tempera-
ture inside the vehicle. Air temperature, airflow
and air distribution are controlled automatically.
The automatic mode is turned on using the
AUTO] button. AUTO mode switches off once a
button in the climate control system is pressed.


Audi recommends pressing the [AUTO] button
and setting the temperature to 72 °F (+22 °C).


A/C} Cooling mode
The cooling mode only functions with the blower
turned on. The cooling system is turned on and
off with the [A/C] button. The air is not cooled
and humidity is not reduced when cooling mode
is switched off. This can cause fog on the win-
dows. The cooling mode switches off automati-
cally at low outside temperatures.


S$ Blower
You can manually adjust the volume of air gener-
ated by the blower to your preference by turning
the knob (4). The blower should always run at a
low setting to prevent the windows from fogging
70
BFV-0218
and to ensure a continuous exchange of air inside
the vehicle. To have the blower regulated auto-
matically, press the [AUTO] button. If the win-
dows are foggy, press the & button.


@ / @ Temperature
The temperature can be adjusted in small incre-
ments using the dial (2).
Air distribution
The air distribution can be adjusted using the dial
@. To have the air distribution regulated auto-
matically, press the [AUTO] button.


The round air vents in the cockpit are adjustable
=> page 71.
To prevent the side windows from fogging over,
open the side air vents and angle them toward
the side.
< Recirculation mode
In recirculation mode, the air inside the vehicle is
circulated and filtered. This prevents the unfil-
tered air outside the vehicle from entering the
vehicle interior > A\.
The recirculation mode can be turned on manual-
ly or automatically*.
— Pressing the <> button switches recirculation
mode on or off manually.

Wheels

authorized Audi Service Facility to see if you may
use snow chains.
Use fine-mesh snow chains. They must not add
more than 0.53 in (13.5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

Z\ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-

dent.

@) Note
Snow chains can damage the rims and wheel
covers* if the chains come into direct contact
with them. Remove the wheel covers” first.
Use coated snow chains.
@ Tips
When using snow chains, it may be advisable
to limit the ESC > page 105.
ee ceil (mae)
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface anda
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 224.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
230
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 215, fig. 175.
For example: Tread wear 200, Traction AA, Tem-
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and
one half (1 1/2) times as well on the govern-
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B and C. Those grades represent the tire's
ability to stop on wet pavement as measured un-
der controlled conditions on specified govern-
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
SA.
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the >
