ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before you start driving, check all lighting equip-
ment on the trailer while it is hitched to the vehi-
cle.
The headlight range control automatically ad-
justs the light range of the headlights.
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer. The chains should hang
enough so that the trailer can drive around
curves. However, they must not touch the
ground.
Air suspension
Applies to: vehicles with air suspension
The Audi drive select* comfort mode > page 124
must be selected before you adjust the tongue
weight on the trailer and hitch the trailer >@,
=> page 126.
Likewise, the vehicle cannot be raised manually
using the Raise function > page 126.
The air suspension trailer mode must be switched
on.
Applies to MMI: select on the home screen: VE-
HICLE > Settings & Service > Air suspension:

level will no longer be available, even if you are
lowering the vehicle manually.
148

ZA WARNING
Applies to: vehicles with air suspension
— Never turn off trailer mode while driving
when a trailer is hitched, because then the
restrictions for controlling the vehicle level
will be turned off.
— Driving with a trailer on unpaved roads when
the vehicle is raised may change the vehicle
handling. Adapt your speed.
— Note that the vehicle will lower automatical-
ly at certain speeds if you have lifted the ve-
hicle manually.
C) Note
— Applies to: vehicles with air suspension: Se-
lect the Audi drive select* comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
— Attachments retrofitted on the vehicle may
cause damage, especially on the trailer
hitch ball head. In cases of damage, have
the function checked by an authorized Audi
dealer or authorized Audi Service Facility.
@) Tips
— Block the wheels with chocks when parking
on inclines if the trailer is loaded.
— Audi recommends having the vehicle in-
spected between the inspection intervals if
you tow a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Pie Rie Relig
Driving with a trailer requires extra caution.

Speed
Adhere to the legal speed limits. Follow the legal
regulations that are applicable in the country
where you are operating the vehicle.
As the speed increases, the driving stability of
the trailer decreases. Therefore you should not
exceed the maximum legal speed limit when
there are unfavorable road, weather, and/or wind
conditions. This especially applies when driving
downhill.

Assist systems

Assist systems
General information
SP ae eel idol ay

ZA WARNING
— As the driver, you are always completely re-
sponsible for all driving tasks. The assist
systems cannot replace the driver's atten-
tion. Give your full attention to driving the
vehicle, and be ready to intervene in the
traffic situation at all times.
— Activate the assist systems only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— 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.
— For the assist systems to be able to react
correctly, the function of the sensors and
cameras must not be restricted. Note the in-
formation on sensors and cameras
> page 151.

@ Tips
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, vehicle distance, speed,
parking location, wheel placement, etc. The
driver is always responsible for following
the laws that are applicable in the location
where the vehicle is being operated.
— You can cancel a steering or braking inter-
vention by the system, by braking or accel-
erating noticeably, steering, or deactivating
the respective assist system.
— Always check the assist systems settings be-
fore driving. The settings could have been
changed, for example by other drivers or by
using another user.

System limitations
ZA\ WARNING
—The use of an assist system cannot over-
come the natural laws of physics. A collision
cannot be prevented in certain circumstan-
ces.
— Warnings, messages, or indicator lights may
not be displayed or initiated on time or cor-
rectly, for example, if vehicles are approach-
ing very fast.
— Corrective interventions by the assist sys-
tems, such as steering or braking interven-
tions, may not be sufficient or they may not
occur. Always be ready to intervene.
G) Tips
— Due to the system limitations when detect-
ing the surrounding area, the systems may
warn or intervene unexpectedly or too late
in certain situations. The assist systems may
also interpret a driving maneuver incorrectly
and then warn the driver unexpectedly.
— The systems may not function as expected
in unusual driving situations, such as driving
offroad, on unpaved roads, on loose ground,
on inclines, or on grooves in the road.



— The systems may not function correctly in
unclear traffic situations, such as turning
lanes, exit ramps, construction zones, rises
or dips that obstruct visibility, intersections,
toll stations, or city traffic.
— The detection of the surrounding area can
be limited, for example by vehicles driving
ahead or by rain, snow, heavy spray, or light
shining into the camera.
— The steering wheel touch recognition may
be limited when you wear gloves. Steering
intervention requests from the steering as-
sist systems may occur more frequently.
— If accessories have been mounted on the
steering wheel, the steering assist systems
may
be limited. The frequency of steering
intervention requests from the steering as-
sist systems may vary as well.

Driving information

Traffic light information
Applies to: vehicles with traffic light information

Fig. 114 Instrument cluster: traffic light information dis-
play
The traffic light information gives you a speed
recommendation in order to reach the next traffic
light when it is green @, or it informs you of the
wait time at the next red light 2). Once traffic
light
data is received, the traffic light information
will be displayed in the instrument cluster and in
the head-up display*. If the vehicle is in an area
with traffic light information but cannot receive a
traffic light signal, then a gray traffic light sym-
bol will be displayed @).
General information
The traffic light information is subject to system
limitations and may be unavailable or only parti-
ally available in the following situations:
—If the permitted speed limit is exceeded
— If driving below a certain speed limit
— If the next traffic light is less than approxi-
mately 100 feet (30 m) away
—If the estimated wait time at a red light is less
than four seconds
— If there is no traffic light data available
— If emergency response vehicles or public transit
systems are active
— If traffic lights are in construction zones or be-
ing serviced
— If there are warnings from the camera-based
traffic sign recognition*

Driver assistance

Driver assistance
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.
Switching the system on
Applies to: vehicles with cruise control system


ZA WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.
BFV-0220



() Note
— Conventional drive system:Before driving
downhill a long distance on a steep hill, de-
crease your speed and select a lower gear.
This makes use of the engine braking effect
and reduces the load placed on the brakes.
— Plug-in hybrid drive: Before driving downhill
a long distance on a steep hill, decrease
your speed and use the recuperation braking
effect > page 114. This reduces the load on
the brakes.
@ Tips
The brake lights turn on when the brakes are
applied automatically.
