Trailer towing

Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head may
not be exceeded.
If the tongue weight is too low, this affects the
trailer's handling. For driving safety, we recom-
mend to always utilize the maximum permitted
tongue weight, but not exceed it. You can reach
it, for example, by distributing the cargo in the
trailer correctly.
You can determine the tongue weight using a
tongue weight scale, a bathroom scale, or a pub-
lic weigh station, for example.
The permitted tongue weight of your vehicle can
be found in the vehicle documentation or in
=> page 264.
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 preferably in the vehicle luggage
compartment. 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 from sliding out of place.
— 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 226. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom-
mendation.
Winter tires should be mounted on the vehicle
and on the trailer during winter temperatures.
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you
must attach additional exterior mirrors. Adjust
102
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
you are operating the vehicle. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before starting to drive, check all lighting equip-
ment on the hitched trailer.
The headlight range control adjusts automatical-
ly to 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.
@) Note
Attachments retrofitted on the vehicle may
cause damage, especially on the trailer hitch
ball head. In cases of damage, have the func-
tion checked by an authorized Audi dealer or
authorized Audi Service Facility.
G) Tips
— Use chocks when parking on inclines if the
trailer is loaded.
—We recommend also having the vehicle in-
spected between the inspection intervals if
you are towing a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Driving with a trailer
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.

Trailer towing

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.
Hill
When transitioning to hills, trailers may tilt or
sway sooner than when driving on a level surface.
If small swaying movements have already occur-
red, you can stabilize the trailer by firmly braking
immediately. Never try to “straighten out” the
trailer by accelerating.
Downshift before driving on hills to utilize the en-
gine braking effect > A\.
Brakes
When using a trailer with overrun brakes, first
brake gently then quickly. This reduces the risk of
jerking while braking if the trailer wheels lock up.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
ture display when there are high outside temper-
atures, and when driving on long inclines
=> page 13. Shift to a higher gear in a timely man-
ner.

ZA WARNING
Constant braking causes the brakes to over-
heat and substantially reduces braking per-
formance, increases braking distance or caus-

es complete failure of the brake system.

Assist systems

Assist systems
General information
Safety precautions

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 105 or > page 106.

@ 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.

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.
—In trailer mode, some assist systems may be
limited, may not react as usual, or may be
unavailable. Please refer to the instructions
for towing a trailer located in > page 101.
— If accessories have been mounted on the
steering wheel, the ability for the steering
systems to react may be limited.

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.

ZA WARNING
— Always pay attention to the traffic around
you when the cruise control system is in op-
eration. As the driver, you are always respon-
sible 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
hydroplaning), because this increases the
risk of an accident.
— 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.
@) Note
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine brak-
ing effect and relieves the brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

Adaptive speed/cruise
assist
General information
Applies to: vehicles with adaptive cruise assist
Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
The adaptive speed/cruise assist (called only
adaptive cruise assist in the vehicle display and in
the rest of the Owner's Manual) consists of a
speed and distance control system. It assists the
driver by both regulating the speed and main-
taining the set distance to the vehicle driving
ahead, within the limits of the system. If the sys-
tem detects a vehicle driving ahead, the adaptive
cruise assist can brake and accelerate your vehi-
cle within the limits of the system. On open roads
with no traffic, it functions like a cruise control
system. The stored speed is maintained. When
approaching a vehicle driving ahead, the adaptive
cruise assist automatically brakes to match that
vehicle's speed and then maintains the set dis-
tance as much as possible. As soon as the system
does not detect a vehicle driving ahead, adaptive
cruise assist accelerates up to the set speed.

responsible for controlling the vehicle. The
driver is especially responsible for braking,
starting to drive, controlling the speed, and
maintaining the distance to other vehicles.
— Turn on the adaptive cruise assist only if the
surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch the adaptive cruise assist off tempo-
rarily when driving in turning lanes or high-
way exits. This prevents the vehicle from ac-
celerating to the stored speed when in these
situations.


ZA WARNING
If you press the SETI2) button when driving
at speeds below 20 mph (30 km/h), then 20
mph (30 km/h) will be set because that is the
minimum speed that can be set. If no vehicle
is detected ahead of you, the vehicle will ac-
celerate up to that speed.


@ Tips
— Always keep your hands on the steering
wheel. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.
— If you switch the ignition or the adaptive
cruise assist off, the stored speed is erased
for safety reasons.
— When the adaptive cruise assist is switched
on, the ESC and the ASR are switched on au-
tomatically.
— The system cannot be switched off if the
road exceeds the maximum possible grade
for safe operation.
— If you signal to pass and the adaptive cruise
assist suggests a passing maneuver, the
adaptive cruise assist will accelerate just be-
fore changing lanes to shorten the distance
to the vehicle driving ahead.
Setting the distance
Applies to: vehicles with adaptive cruise assist

B4M-0234


Fig. 98 Operating lever: Setting the distance
If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher
the speed, the greater the distance that is need-
ed.

sistance display, a graphic display is shown in-
stead of the indicator lights > page 113, fig. 95.
The display matches the functions of the indica-
tor lights.
When approaching a vehicle driving ahead, the
adaptive cruise assist brakes to the set speed and
then maintains the set distance. If the vehicle
driving ahead accelerates, then the adaptive
cruise assist will also accelerate up to the speed
that you have set.
