(D only functions when the ignition is
switched on. To prevent engine damage, p lease
observe the following notes about the tempera­
ture ranges.
Cold rang e
If o nly the L EDs in the left area of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, full ac­
celerating and heavy engine loads .
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on . If the . indicator light in the Infotain­
ment system display turns on, the coolant tem­
perature is too high
c:> page 12.

(D Note
-Aux iliary head lights and other accessories in
front of the coo ling-a ir intake impa ir the
cooling effect o f the coolant. This increases
the risk of the engine overheating during high outside temperatures and heavy en ­
gine load.
- T he front spoiler a lso helps to distribute
cooling air correctly while driving . If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the eng ine over­
heating w ill increase. See an authorized
Audi dealer or author ized Audi Service Fa­
cility for assistance .
Fuel level
The indicator @ only func tions when the ignition
i s sw itched on. If the fuel level drops below 1.9
gal (7
L), a red LED wi ll light up and the rD indi­
cator light will turn on
c:> page 16 . The LED
blinks red when the fuel level is very low.

(D Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter .
Indicator lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
functions.
With some indicator lights, messages may ap­pear and warning signals may sound. The indica­
tor lights and messages in the display can be cov­
ered by other displays. To show them again, se­ lect the tab for the indicator lights and messages
using the multifunction steering wheel
c;, page 19. If there are several malfunct ions,
you can display them one at a time using the
thumbwheel.
Some ind icator lights in the display can display in
several colors .
Overview
Some indicator lights turn on briefly as a function
check whe n you switch the ign ition on . These sys­
tems are marked with a
,I in the following tables.
If one of these indicator lights does not turn on,
there is a ma lfunction in that system.

Warm and cold Climate control system
Description
The climate control system warms, cools and re­
moves humidity from the air in the vehicle interi­
or. It functions most effectively when the w in­
dows are closed. If there is a build-up of heat in ­
side the vehicle, ventilation can help to speed up
the cooling process.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
Key recognition
Certain settings are automatically stored and as­
signed to the remote contro l key being used .
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
control system, especially with the defrost­
ing and defogging function.
- When the temperature is below freezing,
only use the windshield washer system after
the windsh ield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­
ty .
(D Note
-If you suspect that the climate control sys­
tem is damaged, switch the system off to
Warm and cold
prevent further damage and have it checked
by an authorized Audi dea ler or authorized
Audi Service Facility.
- Repairs to the Audi climate control system
require special technical know ledge and
special tools. See an authorized Audi dealer
or authorized Audi Service 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 win­
dows from 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 switch
the seat heating* or rear window defroster
off temporarily . These systems are availab le
aga in as soon as the energy supp ly has been
restored.
- The flows through the vents under the rear
w indow . Make s ure the openings are not
covered when plac ing clothing on the lug­
gage compartment cover .

automatically adjuste d. In all heati ng mode func ­
tions except
defrost, the blower only switches to
a higher speed once the engine coolant has
reached a certain temperat ure.
~ Adjusting the blower
The blower speed can be adjusted in small incre­
ments using the dial @. The blower should al­
ways run at a low setting to prevent the windows
from fogging and to ensure a continuous ex­
change of air inside the vehicle. You can adjust

This can cause fog on the w indows. Coo ling mode
switches off automatically when the outside tem­
perature is below zero .
The temperature can be adjusted with the con ­
trol @.
