-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment. You
could burn yourself. Let the engine cool off
first until you can no longer see or hear steam or coolant escap ing .
Q) Note
-Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At h igh outside temper­
atures or h igh engine load, the engine cou ld
ove rheat.
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving.
If the spoiler is damaged, this
could red uce the cooling effect and the en­
gine could then overheat . Ask your author ­
ized Audi dealer for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
You shou ld shift to the next lowest gear when
the speed is below 1500 RPM. The beginning of
the red zone in the tachometer indicates the maximum permissib le engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before reaching the red zone, you should shift into the
next h igher gear, choose the Dor S selector lever
position, or remove your foot from the accelera ­
tor pedal.
CD Note
The tachometer needle© c::> page 10, fig. 3
should only be in the red zone br iefly: other­
w ise, this increases the risk of e ngine dam-
age. The location where the red zo ne begins
varies depend ing on the eng ine.
@, For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.

Fuel level
The fue l gauge only works when the ignition is
on.
If t h e fue l level drops below 2.6 gallons (10
lite rs), the bottom LED turns red and the indica­
tor light

Fo r the tank capacity in your veh icle, refer to the
T echn ica l Data c::>
page 2 71.
CD Note
Never drive until the tank is completely emp­
ty. The irregu la r supply of fuel that resu lts
from that can cause t he engine to m isfire. Un­
combusted f uel w ill then en ter the exha ust
system . This can cause ove rheating and dam­
age to the catalytic converter.

-If the 1111 (USA models) . (Canada mod­
els) brake system indicator light turns on to­
gether with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
have failed. Functions that stabilize the ve­
hicle are no longer available . This could
cause the vehicle to swe rve and increase the
risk of sliding. Drive carefully to the nearest
authorized Audi dealer or other qualified
workshop and have the ma lfunction correct ­
ed.
- If the brake warn ing/ indicator light does
not go out after a few seconds and the park­
ing brake is re leased, or lights up while you
are driving, the flu id level in the brake fluid
reservoir is too low. If you believe that it is
safe to do so, proceed immediately at low
speed to the nearest authorized Audi dealer
or qualified repair facility and have the brake system inspected.
- Always keep in mind that after several brake
applications, you will need greater pressure
on the brake pedal to stop your vehicle. Do
not rely on strained brakes to respond w ith
maximum stopping power in critical situa­
tions . You must allow for increased braking
distances. The extra distance used up by
fading brakes could lead to an accident.
PARK /(® ) Electromechanical parking brake
The warning/indicator light monitors the elec ­
tromechanical parking brake.
If the indicator light- (USA models)/ .
(Canada models) turns on, the parking brake was
set .

Warm and cold Climate control system
Description
App lies to vehicles: with three-zone climate control or four ­
zone a utomat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior . It
is the most effective when the windows and sun­
roof* are closed .
If the temperature inside the
parked vehicle becomes very warm, opening the
window briefly will speed up the cooling process.
In all heating mode functions except
defrost, the
blower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensat ion 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.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
T he air pollutants filter must be changed at the
intervals specified in your Warranty
& Mainte­
nance booklet, so that the air conditioner can
properly work .
If you drive your vehicle in an area with high air pollution, the filter may need to be changed
more frequently than specified in your Audi War­
ranty
& Maintenance booklet . If in doubt, ask
your authorized Audi Service Advisor for advice .
Key coded settings
Three-zone climate control: The blower setting
and air distribution are stored automatically and
assigned to the remote contro l key that is in use.
Four-zone automatic climate control: Th e cli­
mate control settings are automatically stored
and assigned to the remote contro l key that is in
use.
Warm and cold
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 condensa­
tion .
- Completely familiarize yourself with the
proper use and function of the heating and
ventilation system and especially how to de­
fog and defrost the windows .
- Never use the windshield wiper/washer sys­ tem in freezing weather until you have warmed the windshield first, using the heat­
ing and vent ilation system. The washer so lu­
tion may freeze on the w indshield and re­
duce visibility.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repa irs to the Aud i air cond itioner require
special technical knowledge and special
tools. Contact an authorized Audi dea ler for
assistance.
@ For the sake of the environment
By reduc ing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
- Keep the air intake slots (in front of the
windshield) free from ice, snow and debris
in order to maintain the proper function of
the climate control system.
- The energy management system may switch
the seat heating* or rear window defroster off temporarily . These systems are availab le
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, ensure
that the openings are not covered.
