rl Air suspension: Vehicle too low Ground
clearance reduced
The ground clearance is very low due to a system
malfunction . Wait u ntil the air su spension sys­
tem has restored normal gro un d clearance. Oth­
erwise, conditions s uch as an uneven road surface
can lead to ve hicle damage.
;;.I C; Electronic Stabilization Control (ESC)
If the bl indicator light blinks while driving, the
ESC or ASR (Anti-Slip Regulation) is act ively regu­

If the
Jjj indicator light turns on, the system has
switched the ESC off. In this case, you can switch
the ignit ion off and then on to switch the ESC on
again. The indicator light turns off when the sys­

System (OBD)
Malfunction Indicator Lamp (MIL)
The Ma lfunction Indicato r Lamp ( MIL) ¢..ijj in the
instrument cluster is part of the On -Board Diag ­
nostic (OBD II) system .
T he warning/indicator lig ht ill uminates w hen the
ignition is switched on and goes out after the en ­
gine starts and the id le has stabilized . This indi ­
cates that the MIL is wor king properly.
If the light doe s not go out after the eng ine is
started, or i lluminates while you are driving, a
malfunction may exist in t he engine system. If
the light ill uminates, the catalytic converter
could be damaged.
Continue driving
w ith reduced powe r (avoiding
s u stained high speeds and/or rapid accelera ­
tions) and have the condit ion corrected. Contact
your authori zed Aud i dea ler .
If the light i lluminates, the electronic speed lim ­
iter may also be malf unctioning. For more infor ­

Your veh icle may be factory equipped with ti res
that are rated for a maxim um speed of 130 mph
(210 km/h) . This is less than the maximum speed
of your vehicle . To reduce t he risk of sudden tire

failure and loss of contro l if the vehicle is operat ­
ed at excessive speeds, your vehicle also has an
e lectronic speed limite r. The elect ronic speed
li miter prevents your ve hicle from go ing faster

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
