With some indicator lights, messages may ap-
pear and warning signals may sound. The indica-
tor lights and messages may be covered by other
displays. To show them again, select the second
tab for messages with the multifunction steering
wheel > page 13.
Some indicator lights in the display can display in

Coolant temperature
display
Applies to: vehicles with a coolant temperature indicator
The coolant temperature display @) > page 12
only functions when the ignition is switched on.
To reduce the risk of engine damage, please ob-
serve the following notes about the temperature
ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem-
perature yet. Avoid high engine speeds, full accel-
eration, 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 instru-
14
ment cluster display turns on, the coolant tem-
perature is too high > page 227.
() 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 @) > page 12 displays the engine
speed in revolutions per minute (RPM). The be-
ginning of the red zone in the tachometer indi-
cates the maximum permissible engine speed for
all gears once the engine has been broken in. Be-
fore reaching the red zone, you should shift into
the next higher gear, select the "D" or "S" selec-
tor lever position, or remove your foot from the
accelerator pedal.
Engine speed limitation
If the tA 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 is deactivated if you
release the accelerator pedal while the engine is
at normal operating temperature.
If the engine speed limitation was activated by
an engine control malfunction, the By 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. >

Resetting values to zero
Requirement: the Consumption, Short-term
memory, or Long-term memory display must be
selected.
> To reset the values in the respective memory to
zero, press and hold the left thumbwheel on
the multifunction steering wheel for one sec-
ond.
Depending on the vehicle equipment, you can call
up the following displays in the on-board com-
puter one at a time by turning the left thumb-
wheel on the multifunction steering wheel:
—Time and date > page 212
— Level
— Digital speedometer
— Average consumption > page 16
— Range
— Short-term memory overview
— Long-term memory overview
— Energy consumers > page 16
— Driver assistance
— Traffic sign recognition and traffic light infor-
mation
Short-term memory and long-term memory
The short-term memory collects driving informa-
tion from the time the ignition is switched on un-
til it is switched off. If you continue driving within
two hours after switching the ignition off, the
16
new values will be included when calculating the
current trip information.
Unlike the short-term memory, the long-term
memory is not erased automatically. You can se-
lect the time period for evaluating trip informa-
tion yourself.
Average consumption
The current consumption can be shown using a
bar graph. The average consumption stored in
the short-term memory is also displayed. If the
bar is green, your vehicle is saving fuel (for exam-
ple, using recuperation).
Energy consumers
The Energy consumers view lists other equip-
ment that is currently affecting fuel consump-
tion. The display shows up to three equipment
items. The equipment using the most power is
listed first. If more than three items using power
are switched on, the equipment that is currently
using the most power is displayed. A gauge also
shows the current total consumption of all other
equipment.

Voice recognition system
General information
Applies to: vehicles with voice recognition system
You can operate many functions in the vehicle
easily using voice commands.
Using the voice recognition system optimally
> Speak clearly and distinctly at a normal volume.

and do not leave long pauses.
> Close the doors, the windows, and the sunroof*
to reduce background noise. Make sure that
passengers are not speaking when you are giv-
ing a voice command.
> Do not direct the vents toward the hands-free
microphone, which is in the roof headliner near
the front interior lights.

driver, you have complete responsibility for
safety in traffic. Only use the functions in
such a way that you always maintain com-
plete control over your vehicle in all traffic
situations.

emergencies because your voice may change
in stressful situations. The system may take
longer to dial the number or may not be
able to dial it at all. Dial the emergency
number manually.

General information
Z\ WARNING
— If you leave the vehicle, switch the ignition
off and take the key with you. This applies
particularly when children remain in the ve-
hicle. Otherwise, children could start the ve-
hicle or operate electrical equipment (such
as power windows), which increases the risk
of an accident.

— Applies to vehicles with anti-theft alarm sys-
tem: When the vehicle is locked from the
outside, no one - especially children - should
remain in the vehicle, because the windows
can no longer open from the inside
=> page 36, Anti-theft alarm system.
Locked doors make it more difficult for
emergency workers to enter the vehicle,
which puts lives at risk.
All doors and the luggage compartment lid can
be centrally unlocked and locked at once. You can
select in the MMI if the entire vehicle or only the
driver's door should unlock when unlocking the
vehicle > page 34. The turn signals flash twice
when you unlock the vehicle and flash once when
you lock the vehicle. If they do not flash when
locking, check if all doors and lids are closed.

Depending on the vehicle equipment, you may
have different options for centrally unlocking and
locking your vehicle.

— Sensors in the door handles > page 38
— Lock cylinder in the driver's door > page 36

Vehicle key
The term “vehicle key” refers to the remote con-
trol key or convenience key*. The convenience
key* is a remote control key with special func-
tions > page 38 and > page 95.
Automatic locking
If you unlock the vehicle but then do not open
any of the doors, the luggage compartment, or
the hood within a short period time, the vehicle
locks again automatically. This feature prevents
the vehicle from being accidentally left unlocked
for a long period of time.
Automatic locking (Auto Lock)
The Auto Lock function locks all doors and the
luggage compartment lid once the speed has ex-
ceeded approximately 9 mph (15 km/h). The ve-
hicle will unlock again if the unlock function in
the central locking switch is pressed, the “P” gear
is engaged, or the ignition is switched off.
You can open the doors individually from the in-
side by pulling the door handle one time. To open
the rear doors individually, you must pull the
door handle twice.
In the event of a crash with airbag deployment,
the doors will also automatically unlock to allow
access to the vehicle.
Unintentionally locking yourself out
Only lock your vehicle when all of the doors and
the luggage compartment lid are closed and
there is no key in the vehicle. This reduces the
risk of locking yourself out accidentally.
The following features help to reduce the risk of
locking your vehicle key in the vehicle:
— If the driver's door is open, the vehicle cannot
be locked by pressing the & button on the re-
mote control key or by touching the locking
sensor* on a door.
— If the vehicle key that was used most recently is
inside the luggage compartment, the luggage
compartment lid will automatically open again
after it closes > ©.
— If the vehicle key that was last used is detected
inside the vehicle, then the vehicle cannot be
locked from the outside > ©.
