70 Warm and cold
Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effect ive 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.
I n all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of water under the ve­
hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The pollutant filter removes pollutants s uch
as dust and pollen from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work.
If you drive your vehicle in an area with h igh
a ir po llution, the fi lter may need to be
changed more frequently than specified in
your Aud i Wa rranty
& Ma intenance booklet. If
in doubt, ask your authorized Audi Service Ad ­
visor for advice .
Key coded settings
The climate control settings are automat ically
stored and assigned to the remote control key
that is in use. These settings are different
when the power top is open or closed .
A WARNING
Reduced visibility is dangerous and can
cause accidents. -
- For safe driving it is very important that
all windows be free of ice, snow and con­
densation.
- Comp letely familiarize yourself with the
proper use and function of the heating
and ventilation system and especially how to defog and defrost the windows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­ shie ld and reduce visib ility.
(D Note
- If you suspect that the air conditioner has been damaged, switch the system
off to avoid further damage and have it
inspected by a qualified dealership.
- Repairs to the Audi air conditioner re­
quire special technical know ledge and
special tools. Contact an authorized Aud i
dea ler fo r assistance.
@ For the sake of the environment
By reducing the amount of fuel you use,
you also reduce the amount of pollutants
emitted into the air.
(D Tips
- Keep the air intake s lots (in fro nt of the
w indshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy management system may
switch the seat heating* or rear window
defroster off temporarily . These systems
are available again as soon as the energy
balance has been restored.
- Air escapes through vents under the rear
window. When placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.

The stored speed and the green symbol
lij;(l)~i4 (US model) 1B (Canadian model) are
shown in the display
r:::;, fig. 95. The display
may vary, depending on the type of display in
your veh icle.
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
A WARNING
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles. -
For reasons of safety , cruise control
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
plan ing) - risk of accident.
- Turn off the cruise control temporarily
when enter ing turn lanes, highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "resting"
your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the drive r's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off . The other cruise control functions re­
main active as long as the indicator light
[ff;(l)~i4 (US models) ;B (Canadian mod­
els) is on.
(D Tips
The brake lights illuminate as soon as th e
brakes app ly automatically.

ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti-slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering" and
e lectronic interaxle differentia l lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certa in s ituations whe n you need
l ess t raction, you can switch off ASR by p ress­
i ng the bu tto n
[ru ¢ fig. 167 or ¢ fig. 168. Be
sure to sw itch ASR on ag ain when you no lon­
ger need less trac tion.
Anti -lock braking system (ABS)
ABS prevents t he wheels from locking up
when braking. The veh icle can still be st eered
even d uring ha rd b rak ing . Apply steady p res­
sure to the br ake pedal. Do no t pu mp the ped­
a l. A puls ing in t he bra ke peda l ind icates that
the system is he lping yo u to b rake the vehicle .
Brake assist system
The brake assist system can decrease bra king
d ista nce. It increases braking powe r w hen the
d river p resses the brake pedal quickl y in eme r­
gency situa tions . You mus t press and ho ld the
brake peda l until the situation is over. In
ve hicles with adaptive cruise contro l", the
brake assist system is more sensit ive if the
d ista nce detected to t he vehicle a head is too
smal l.
Anti-slip regulation (ASR)
ASR reduces engi ne power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinning and
tra nsfers t he d rive powe r to the other d rive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL a utomatica lly switches
off to help keep the bra ke on the braked whee l
from overheating. EDL will switch on aga in au­
tomatically when conditions have returned to
normal.
Dynamic steering*
On vehicles wi th dynam ic s teering *, ESC he lps
sta bilize the steer ing in crit ica l sit uat ions.
Electronic interaxle differential lock*/
selective wheel torque control*
T he ele ctroni c in te raxle di fferentia l lock ( fron t
whee l drive) o r th e se lective whee l torque
control (all -whee l drive) operates when driv­
ing t hro ugh cu rves. The front wheel on the in­
s ide of the c urve or both whee ls on the inside
of the curve are braked selectively as needed .
Th is mi nimizes sliding in the front wheels and
allows for more precise d rivi ng through
cu rves . The a ppl icable syste m may not acti­
vate when dr iv ing in wet o r snowy cond itions.

Plea se start the engine soon or the system
will be tu rned off.
The warning ind icates that the system will be
turned off automa tic ally after 3 m inu tes. If
you wish to cont inue using the functions , you
have to start the engine .
With the engine running
Although ele ct ric al e nergy is generated when
the vehicle i s be ing driven , the battery can be­
come d ischarged. This happens most ly w hen
little energy is being generated and a great
deal consumed and the battery 's state of
charge is not optima l.
To br ing the energy balance back into equili­
brium, cons umers which require especia lly
l arge amounts of energy are temporarily c ut
back or switched off. Heating systems in par·
ticular requ ire a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they have been temporar ily cut back o r switched
off. These systems will be ava ilable again as
soon as the ene rgy ba lance h as been restored.
You will a lso notice that engine idle speed has
been inc reased slightly . This is norma l and not
a cause fo r conce rn . By increas ing engine idle
speed the add itiona l ene rgy required is gener­
ated and the ba tte ry is charged.
