Vehicle sound
Applies to: vehicles with plug-in hybrid drive
The electric drive system generates considerably
less noise than a combustion engine. An artificial
engine sound is generated when driving electri-
cally so that the vehicle can be heard from the
outside when driving. The vehicle sound auto-
matically fades out at higher speeds when the
sounds from the tires and wind start increasing.

ZA WARNING
Other road users may not be able to defini-
tively hear electric vehicles when they are
driving. This increases the risk of an accident
particularly when driving in areas with little
traffic, when maneuvering, or when driving in
reverse.

driving

Your driving style greatly influences the amount
of fuel and energy consumed, the environmental
impact, and the wear on the engine, brakes, and
tires. Note the following information for efficient
and environmentally-conscious driving:
— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system.
— Utilize the engine braking effect.
— Avoid driving short distances when possible.
G) Tips
The amount of noise produced by the vehicle
can increase significantly when driving with a
sporty style. Show respect to others around
you and the environment with the way you op-
erate your vehicle, especially at night.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
@ Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be limited or
switched off.

Driving dynamic

Based on the selected setting, the air suspen-
sion* will adjust the ground clearance and the ac-
tive suspension* will provide various degrees of
compensation for vehicle movements.
Engine sound
The engine sound adapts and can be subtle to
sporty.
Suspension
Air suspension
Applies to: vehicles with air suspension
The air suspension is an electronically-controlled
suspension and leveling system. The firmness of
the suspension will adapt to the driving condi-
tions and the driving situation. The system balan-
ces out changes in load. The vehicle level will also
adapt gradually to the vehicle speed in order to
reduce the wind resistance at high speeds and in-
crease the ground clearance at low speeds. The
settings depend on the selected Audi drive se-
lect* mode.
Displaying the vehicle level
> Applies to: MMI: Select on the home screen:
VEHICLE > Audi drive select.
» Applies to: Audi tablet: Select on the home
screen: VEHICLE > Driving data.
The filled-in boxes represent the current vehicle
level. The more boxes that are filled in, the high-
er the ground clearance. The box that corre-
sponds with the current vehicle level will flash
while the vehicle is lifting or lowering. The target
level is indicated by a red outline.
Raising the vehicle
>» Applies to: MMI: Select on the home screen:
VEHICLE > Audi drive select.
> Press Raise to reach the highest vehicle level
and thus the maximum ground clearance.
> Press Lower to lower the vehicle down again.
The vehicle will lower when at speeds of approxi-
mately 22 mph (35 km/h) and lower. This func-
tion may only be used temporarily when in-
creased ground clearance is necessary. It is not
intended for long drives.
CG) Note
— Also refer to the information about ground
clearance > page 130.
— When transporting the vehicle on a road
carrier, rail carrier, ship carrier, or other car-
rier, it may only be secured at the running
surfaces of the tires (circumference). Secur-
ing the vehicle at the axle components, sus-
pension struts, or towing eyes is not permit-
ted because the pressure in the air suspen-
sion struts can change during transport. The
vehicle might not be secured sufficiently if
this happens.
Active suspension
Applies to: vehicles with active suspension
The active suspension enhances the air suspen-
sion with an electromechanically-controlled sus-
pension system. It selectively influences rolling
movements when driving around curves and
pitching movements, for example when braking
and accelerating. It also reduces lifting move-
ments when driving over bumps. The settings de-
pend on the selected Audi drive select* mode.
The curve tilting function is also switched on in
the comfort+ Audi drive select* mode. This func-
tion reduces the force on the vehicle passengers
when driving around curves by tilting the vehicle
toward the inside of the curve.
Display
You can display the principal functions of the ac-
tive suspension.
> Applies to: MMI: Select on the home screen:
VEHICLE > Vehicle data.
> You may need to scroll down to the Active sus-
pension display.
It will display how the vehicle body movements
are compensated at each wheel. The more the
cylinder is filled in, the more the system is inter-
vening. Please note that the display here is not to
scale.

Trailer towing

Trailer towing
Driving with a trailer
General information
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

Driving information

Driving information
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps the driver to
stay below a specified maximum speed. A warn-
ing threshold can be set in the MMI for this pur-
pose.
Once the speed slightly exceeds the stored
threshold, the speed warning system will alert
the driver with an indicator in the instrument
cluster and a warning tone. Once the speed drops
below the stored maximum speed, the indicator
will turn off.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
@) Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.
Setting the warning threshold

Fig. 120 Instrument cluster: traffic sign recognition
The traffic sign recognition shows the traffic
signs detected by the front camera in the instru-
ment cluster display and in the head-up display”.
Data from the navigation system is also included
in the display. Up to three traffic signs can be dis-
played in the instrument cluster at once. The
speed limit that is currently applicable is dis-
played in the status line. If necessary, it will be
hidden if the system detects that turning right is
prohibited at a red light. The display in the head-
up display* can be switched off > page 37.
Within the limits of the system and depending
on the market, speed limit restrictions @ in
school zones, highways, construction zones, or at
night may be displayed.
Limitations
The traffic sign recognition is subject to certain
system limitations and may be unavailable or on-
ly partially available in the following situations:
— When visibility is poor, such as in snow, rain,
fog, or heavy spray
—When there is glare, for example from oncom-
ing traffic or the sun
— At high speeds
— If the camera's visual field > page 155 is cov-
ered, for example by dirt or stickers. Cleaning

and Tires
General information
> Check your tires regularly for
damage, such as punctures,
cuts, cracks, and bulges. Remove
foreign objects from the tire
tread.
>If driving over curbs or similar
obstacles, drive slowly and ap-
proach the curb at an angle.
>Have faulty tires or rims re-
placed immediately.
>Protect your tires from oil,
grease, and fuel.
>Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
>Lay tires flat when storing and
store them ina cool, dry location
with as little exposure to light as
possible.

A WARNING
—Never drive faster than the
maximum permitted speed for
your tires. This could cause the
tires to heat up too much. This
increases the risk of an acci-
dent because it can cause the
tire to burst.


—Always adapt your driving to
the road and traffic condi-
tions. Drive carefully and re-
duce your speed on icy or slip-
pery roads. Even winter tires
can lose traction on black ice.

() Note
—Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom-
mends using winter tires dur-
ing the winter months. Low
temperatures significantly de-
crease the elasticity of summ-
er tires, which affects traction
and braking ability. If summer
tires are used in very cold tem-
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
—Burnished, polished or
chromed rims must not be
used in winter driving condi-
tions. The surface of the rims
does not have sufficient corro-
sion protection for this and
could be permanently dam-
aged by road salt or similar
substances.
