Instrument cluster

Reducing the display
Depending on the vehicle equipment, you can
hide the central area in the instrument cluster.
> Select on the instrument cluster: vehicle func-
tions tab > E] button > Reduced display.
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-
ment cluster display turns on, the coolant tem-
perature is too high > page 281.
@) 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 (@) 9 page 12 displays the engine
speed in revolutions per minute (RPM). The be-
ginning of the red zone in the tachometer indi-
14
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.
Displaying the tachometer
Applies to: vehicles with plug-in hybrid drive
> Applies to: MMI: Select on the home screen:
SETTINGS > Display & brightness > Audi virtu-
al cockpit > Left dial > Tachometer or Com-
bined.
Engine speed limitation
If the Bw 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 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.
C) 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.

4N0012721BF
Storage and convenience

Additional storage
Depending on vehicle equipment, there are a va-
riety of storage areas, compartments, and retain-
ers, such as the glove compartment, for safely
storing and securing objects.

Z\ WARNING
—To reduce the risk of injury, make sure all
storage compartments are always closed
while driving.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— Only use the storage compartments in the
door trim panels to store small objects that
will not stick out of the compartment and
impair the function of the side airbags.
— Only lightweight clothing should be hung
from the garment hooks in the vehicle. Do
not use clothes hangers to hang clothing.
The pockets of the clothing must not con-
tain any heavy, breakable, or sharp-edged
objects. This could impair the effectiveness
of the side curtain airbags.
— Make sure your view toward the rear is not
blocked, for example by hanging clothing or
objects in the vehicle.

Luggage compartment
General information
All pieces of luggage or objects must be securely
fastened in the luggage compartment. Note the
following to maintain good vehicle handling:
> Distribute the load evenly in the luggage com-
partment.
> Stow heavy luggage as far forward in the lug-
gage compartment as possible.
> Use non-elastic cords attached to the tie-downs
to secure objects.

ZA WARNING
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-



ing maneuvers, which increases the risk of
an accident. Always stow objects securely in
the luggage compartment and secure them
at the tie-downs. Use straps suitable for
heavy objects.
— If pieces of luggage or objects are secured
to the tie-downs with unsuitable or dam-
aged straps, this can increase the risk of in-
jury during braking maneuvers or accidents.
— When transporting heavy objects, the vehi-
cle characteristics will change due to the
shift in the center of gravity, which increases
the risk of an accident. You may need to
adapt your driving style and speed to the
current conditions.
— The cargo net* is only strong enough to se-
cure light objects. Heavy objects are not ade-
quately secured. Attempting to secure heavy
objects increases the risk of injury.
— Never exceed the permitted axle and load
and vehicle weight > page 344.
— Never secure a child safety seat to the tie-
downs.
— Never leave your vehicle unattended, espe-
cially if the luggage compartment lid is
open. Children could enter the luggage com-
partment and close the luggage compart-
ment lid from the inside. This creates the
risk of fatal injury, since the children would
be locked in and may not be able to escape
by themselves.
— Do not allow children to play in or on the ve-
hicle. Close and lock the luggage compart-
ment lid as well as all other doors when you
leave the vehicle.
— Never transport passengers in the luggage
compartment. Every passenger must be cor-
rectly secured with the safety belts in the
vehicle > page 80.

® Note
— Make sure that the heating grid strips for
the rear window defogger are not damaged
by abrasive objects.
— Plug-in hybrid drive: Never exceed the maxi-
mum cargo weight for the cargo floor that is
specified on the sticker. Otherwise, the
high-voltage battery that is located

Warm and cold

Warm and cold
Climate control system
One of the following options may be available,
depending on vehicle equipment:
— A deluxe automatic climate control system with
3 zones where the temperature, air distribu-
tion, and air supply can be set separately on the
left front side, the right front side, and in the
rear
— A deluxe automatic climate control system with
4 zones to individually adjust the temperature,
air distribution, and amount of ventilation at all
of the seats
The climate control system warms, cools, dehu-
midifies, and filters the air in the vehicle interior.
It is the most effective when the windows and
panoramic glass roof* are closed. If there is a
build-up of heat inside the vehicle, ventilation
can help to speed up the cooling 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.
@ For the sake of the environment
Energy can be saved by switching off the A/C
mode.
@ Tips
— To prevent interference with the heating or
cooling output and to prevent the windows
from fogging over, the air intake in front of
the windshield must be free of ice, snow,
and 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.
100

— 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.
