@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.
— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa-
cility for assistance.
Tachometer
The tachometer (2) > page 10, fig. 3 displays the
engine speed in revolutions per minute (RPM).
The beginning of the red zone in the tachometer
indicates the maximum permissible engine speed
for all gears once the engine has been broken in.
Before reaching the red zone, you should shift in-
to the next higher gear, choose the "D" or "S" se-
lector lever position, or remove your foot from
the accelerator pedal.
Engine speed limitation
Applies to: vehicles with center armrest
If the BB indicator light turns on, the engine will
be automatically limited to the RPM displayed in
the instrument cluster. This will protect the en-
gine components, for example during a cold start
or from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature
range and you have released the accelerator ped-
al once.
If the engine speed limitation was activated by an
engine control malfunction, the B§ indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam-
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im-
mediately to have the malfunction corrected.
CG) Note
The needle in the tachometer may only be in
the red area of the gauge for a short period of
time before there is a risk of damaging the
engine. The location where the red zone be-
gins varies depending on the engine.
Odometer
11:30"

Fig. 4 Instrument cluster: odometer and reset button
The trip odometer and odometer are displayed in
the status line ©) > page 10, fig. 3.
The trip odometer shows the distance driven
since it was last reset. It can be used to measure
short distances. The odometer shows the total
distance that the vehicle has been driven.
Resetting the trip odometer

> Press the reset button [0-0] on the instrument
cluster. The trip odometer will be reset to zero.
(i) Tips
Distances are displayed in mi (miles) or km
(kilometers).

Outside temperature
display
The outside temperature is displayed in the sta-
tus line ©) > page 10, fig. 3.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the motor.

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

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.

Auto recirculation. When switched on, auto-
matic recirculation controls the recirculation
mode automatically. You must press the $Y but-
ton if fog forms on the windows.



Pressing the <> button, [AUTO], or the 8 button
switches recirculation mode off.

® Defroster
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off. The temperature should be
set at +72 °F (22 °C) or higher. The temperature
is controlled automatically. Depending on the
outside temperature, the A/C cooling mode may
automatically switch on.

The [AUTO] button switches the defroster off.
& Rear window defogger
If the rear window defogger is activated when the
ignition is switched on, the battery management
determines based on the battery charge if it is
possible to turn on. Otherwise, the rear window
defogger functions with the engine running and
switches off automatically after 10 - 20 minutes,
depending on the outside temperature.
To prevent the rear window defogger from
switching off automatically, press and hold the
® button for more than two seconds. This re-
mains stored up to approximately 15 minutes af-
ter turning off the ignition.

@ on the air vent. To stop the air flow, move the
lever all the way to the left.
Seat heating

Fig. 80 Air vents: seat heating
Pressing the w button switches the seat heating
on at the highest setting (level 3). The LEDs indi-
cate the temperature level. To reduce the tem-
perature, press the button again. To switch the
seat heating off, press the button repeatedly un-
til the LED turns off.

Z\ WARNING
You should not use the recirculation mode for
an extended period since no fresh air is drawn
in. With the air-conditioning switched off, the
windows can fog up, which increases the risk
of an accident.

ZA WARNING
Individuals with reduced sensitivity to pain or
temperature could develop burns when using
the seat heating function. To reduce the risk
of injury, these individuals should not use seat
heating. >

Checking and Filling


High voltage! Switch off the engine be-
fore coming into contact with any igni-
tion system components!

The catalytic converter can be damaged
"271i if the oil level is too high!

Always follow the instructions in the op-
aa erating manual.


ZA\ WARNING
— Turn the engine off.
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Allow the engine to cool.
— Keep children away from the motor com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contained
in the coolant) can catch fire.
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— Never open the hood when there is steam or
coolant escaping from the motor compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
—The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure. There
is a risk of burns
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“P” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.

marking @), then engine oil must be added.


@| Do not add engine oil.

@) Note
— The engine oil level must not be below the
marking @, because this increases the risk
of engine damage.
— After adding engine oil, the oil level must
not be above the marking (2) > fig. 169, be-
cause this increases the risk of catalytic con-
verter and/or engine damage. If the oil level
is above the marking Q), drive to an author-
ized Audi dealer or authorized Audi Service
Facility immediately to have any engine oil
extracted. Avoid high engine speeds, full ac-
celeration, and heavy engine loads.
G) Tips
The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km), de-
pending on driving style and operating condi-
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). The engine oil
level must be checked regularly. It is best to
check each time you refuel your vehicle and
before long drives.
— Because of the lubrication and cooling of
the engine, combustion engines consume
oil. The oil consumption varies depending
on the engine and may change during the
service life of the engine. Engines generally
consume more oil at the beginning during
the break-in period. Then oil consumption
stabilizes after the break-in period.
— Under normal conditions, oil consumption
depends on the quality and viscosity of the
oil, the engine RPM, the climate conditions,
and the road conditions. The dilution of oil
from condensation or fuel residue as well as
the age of the oil also play a role. Because
engine wear increases with mileage, oil con-
sumption will increase again over time until
it may be necessary to replace worn compo-
nents.
— Because all these variables play a role, it is
not possible to define an oil consumption
standard. Therefore, the oil level must be
checked regularly.
— If you believe that your engine has increased
its oil consumption, contact an authorize
Audi dealer or authorized Audi Service Fa
d
cility to determine the cause. Please note
that an exact oil consumption measurem ent
must be done with the necessary care and
accuracy and may take time. An authorized
Audi dealer or authorized Audi Service Fa
cility is trained in accurately measuring the
oil consumption.
