Trailer towing

Trailer towing
Driving with a trailer
er else)
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.

ZA\ 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 > @.
118

ZA\ WARNING
— Never mount a "weight-distributing" or
"load-balancing" trailer coupler as the trailer
hitch. The vehicle was not designed for
these types of trailer hitches. The trailer
hitch can malfunction and the trailer can
break off from the vehicle.
— If the trailer is equipped with electronic
brakes, these brakes cannot be activated by
a factory-installed control system, which in-
creases the risk of an accident.
—To reduce the risk of injury, always remove
the ball hitch mount if no trailer is mount-
ed
@) 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.

Towing capacity

The permitted towing capacity must not be ex-
ceeded under any circumstances > page 314.
You can drive up larger inclines if you are not us-
ing the maximum towing capacity.
The specified towing weights only apply at eleva-
tions up to 3,200 feet (1,000 m) above sea level.
As the elevation increases, the engine power de-
creases due to the decreasing air pressure. This
reduces the hill climbing ability and towing ca-
pacity. For every additional 3,200 feet (1,000 m),
the maximum permitted towing weight must be
reduced by approximately 10%. The permitted
towing weight is the combined weight of the
(loaded) vehicle and the (loaded) trailer.
Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head must
not be exceeded.
For driving safety, Audi recommends always us-
ing
the maximum permitted tongue weight, but
do not exceed this weight. Distributing the cargo >

Trailer towing

Vehicle levels below the values set in the comfort
level will no longer be available, even if you are
lowering the vehicle manually.

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.
©) 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.
G) 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.
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.
As the speed increases, the driving stability of
the trailer decreases. Therefore you should not
120
exceed the maximum legal speed limit when
there are unfavorable road, weather, and/or wind
conditions. This especially applies when driving
downhill.
Hill
When you start driving uphill or downhill, trailers
may tilt or sway sooner than when driving ona
level surface. If small swaying movements have
already occurred, you can stabilize the trailer by
firmly braking immediately. Never attempt 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 14. Shift to a higher gear in a timely man-
ner.

Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-
formance, increase braking distance, or cause
complete failure of the brake system.

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.

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.

C) 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 reduces the load placed on the
brakes.
@) Tips
The brake lights turn on when the brakes are
applied automatically.

Fig. 118 Upper display: distance indicator
If the sensors detect an obstacle, audible and vis-
ual signals will warn you.
Visual warnings
The visual warnings in the upper display help you
to detect the critical vehicle area and to estimate
the distance to an obstacle.
Red segments (2) show detected obstacles that
are in your vehicle's path. The red lines @) mark
the expected direction of travel based on the
steering angle. A white segment (8) indicates a
detected obstacle that is outside of the vehicle's
path. The closer your vehicle comes to the obsta-
cle, the closer the segments will move to the ve-
hicle. The collision area has been reached when
the next to last segment is displayed. Obstacles
in the collision area, including those outside of
the vehicle's path, are shown in red. Do not con-
tinue driving farther.
Audio signals
The closer your vehicle gets to a detected obsta-
cle, the shorter the time between the audible sig-
nals. A continuous tone sounds when an obstacle
is less than approximately 1 foot (0.30 m) away
from the front or rear of the vehicle. A continu-
ous tone sounds when an obstacle is less than
approximately 0.7 feet (0.20 m) away from the >

Parking and maneuvering


— Park assist plus is an assist system. The driv-
er is still responsible for monitoring the ve-
hicle's surroundings and preventing colli-
sions when using the system.
— When using park assist plus to drive into or
out of a parking space, the steering wheel
turns quickly on its own. Reaching into the
steering wheel spokes while this is happen-
ing can result in injury.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.

@) Tips
— You can reduce the speed specified by the
system at any time by pressing the brake
pedal.
— The system can incorrectly interpret parking
space barriers (such as parking curbs). Take
over the parking process = page 173 if the
vehicle is not completely inside the parking
space or if the vehicle tries to drive over the
parking space barrier.
— The image in the display is an enlarged and
distorted image. Under certain circumstan-
ces, objects may appear different and un-
clear on the display. This is especially true if
there are objects that do not touch the
ground, such as the bumper of a parked ve-
hicle or the rear of a truck. Drive with spe-
cial care and do not use the image if neces-
sary.
— Applies to vehicles with air suspension: The
accuracy of the orientation lines and green
surfaces in the display decreases when the
vehicle is raised or lowered with the air sus-
pension.

ended if additional corrective movements are
no longer necessary and the specified steering
wheel angle is sufficient to drive out of the
parking space. Resume control of the steering
wheel >@).






Pause park assist plus > page 173.

Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— Press and hold the [>>P] button only if you
are sure that there are no obstacles in the
vehicle's path or under the vehicle, and that
no obstacles will move into the vehicle's
path. >

Parking and maneuvering


— Remote controlled parking is only an assist
system. The driver is always responsible for
maneuvering, driving, and stopping the ve-
hicle and performing other driving maneu-
vers.
— Do not use this function if the vehicle cannot
move freely, for example when on a vehicle
jack.
— Failing to pay careful attention to the vehi-
cle's surroundings increases the risk of an
accident. Sensors and cameras have spots in
which the surrounding area cannot be de-
tected. Objects, animals, and people may
only be detected with limitations may not
be detected at all. Always monitor the traf-
fic as well as the vehicle's surroundings with
direct eye contact. Stay near the vehicle
while controlling it. Make sure you have a
clear view of the vehicle and the area sur-
rounding it. Do not become distracted.
— Applies to: vehicles with anti-theft alarm
system: There is a risk of fatal injury for peo-
ple locked in the vehicle, especially children.
The vehicle is locked during remote control-
led parking. Make sure there are no persons
inside the vehicle both before and after us-
ing remote controlled parking.
— There is a risk of asphyxiation. Never allow
the engine to run in confined spaces. After
remote controlled parking, make sure the
engine is off.
— Malfunctions when using the myAudi app in-
crease the risk of an accident. Do not exit
the app during the parking process, and
make sure that it does not go into the device
background, for example by accepting an in-
coming call. Observe the operating instruc-
tions from the manufacturer of your mobile
device.
— There is a risk of accident if the connection is
interrupted. In certain situations, the con-
nection between the mobile device and the
vehicle can be interrupted, for example from
other radio devices or when the distance to
the vehicle is too far. Make sure the connec-
tion is sufficient, and when in doubt, resume
parking the vehicle yourself.


— Blocking notifications, tones, and vibrations
increase the risk of an accident. The myAudi
app can only warn you if dangers are detect-
ed if you make sure that your mobile device
allows all notifications, tones, and vibra-
tions for the myAudi app.


174
@) Note
— Do not use remote controlled parking when
transporting cargo that projects outside of
the vehicle or when snow chains are mount-
ed.
— Remote controlled parking may guide the
vehicle either away from curbs or onto them
if other vehicles are parked on the curb.
Make sure that your vehicle's tires and rims
are not damaged. Resume control of the ve-
hicle in time or stop the parking process if
needed to prevent damage.
— In parking spaces without curbs, maintain a
distance of at least 19 inches (50 cm) from
walls and buildings in order to reduce the
risk of vehicle damage.
G) Tips
— Follow the legal regulations in the country
where you are operating the vehicle when
using remote controlled parking. Remote
controlled parking may be prohibited in
some countries. The system may be unavail-
able in countries where it has been deacti-
vated in order to comply with legal regula-
tions. Data will not be transmitted to Audi.
The driver is always responsible for adhering
to the regulations applicable in the country
where the vehicle is being operated.
— Any individual that uses the mobile device
for remote controlled parking is considered
the driver and is participating in traffic. The
driver is always responsible for adhering to
the regulations for using remote controlled
parking that are applicable in the country
where the vehicle is being operated.
— Do not endanger any other road users when
using remote controlled parking. Testing re-
mote controlled parking in a parking lot
with minimal traffic is recommended. >

Parking and maneuvering

@) Tips
— When parking in garages, you can be
straight in front of the garage or at a slight
angle in front of the garage. You will have
the best results when you align and stop
your vehicle as straight as possible in front
of the garage.
— If there is enough space in a two-car garage,
the system automatically selects the park-
ing position in front of the vehicle that the
driver has selected.
