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.

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.

Trailer towing

Trailer towing
Driving with a trailer
eT e e eeu)
Your vehicle is primarily intended for transport-
ing people and luggage. However, if you drive
with a trailer, follow the technical requirements,
the operation and driving tips, and the legal reg-
ulations.
Driving with a trailer affects the vehicle's energy
usage, performance, and wear. It also requires
higher concentration from the driver.

Z\ WARNING
Do not transport any people in a trailer due to
the risk of fatal injury.
Technical requirements
Trailer hitch

Only use a trailer hitch with a removable ball
hitch mount and ball hitch. The trailer hitch must
be permitted for the vehicle, the trailer and the
permitted total weight of the trailer being
pulled. Above all, it must be securely and safely
attached to the vehicle trailer.
Never mount a trailer hitch on the bumper. The
trailer hitch must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regularly if the trailer hitch is securely
mounted. Always follow the instructions given by
the trailer hitch manufacturer.
Trailer brakes
If the trailer has its own brake system, then fol-
low the manufacturer specifications. However,
the brake system on the trailer must never be
connected to the vehicle brake system.
Engine cooling system
Driving with a trailer means a higher load on the
engine and the cooling system. The cooling sys-
tem must be designed for additional load and
contain enough coolant > @®.
CG) Note
Longer inclines cannot be driven without a
suitable cooling system, especially if the out-
side temperatures are high. Otherwise, this
increases the risk of engine damage.
Operating instructions
Towing capacity
Your vehicle can only be operated with class 1 or
class 2 trailers.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. Load the trailer based
on the following criteria as much as possible:
— Store objects in the vehicle luggage compart-
ment, if possible. The vehicle should always
carry the heaviest possible load and the trailer
should have the lightest possible load.
— Distribute the load in the trailer so that the
heavy objects are as close to the axle as possi-
ble.
— Secure objects so that they do not slide.
— Utilize the maximum permitted tongue weight
if possible.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker > page 299. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's specifica-
tions.
The trailer and the vehicle should be equipped
with winter tires when driving in winter tempera-
tures.
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you
must attach additional exterior mirrors. Adjust
them so you have a sufficient visibility behind
you.
Exterior lighting
Follow the legal regulations for lighting on your
trailer that are applicable in the country where
