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.

Parking and maneuvering


Applies to: vehicles with rearview camera/peripheral cameras

Fig. 124 Upper display: aiming at a parking space
When parking with the rearview camera or pe-
ripheral camera, the parking system plus audio
and visual warnings* will also assist you
=> page 177.
Visual orientation lines
@ The orange orientation lines show the vehi-
cle's direction of travel >@. Turn the steer-
ing wheel until the orange orientation lines
align with the parking space.
@) Use the blue markings to help you estimate
the distance to an obstacle. Each marking
represents approximately 3 feet (1 meter).
The blue area represents an extension of the
vehicle's outline by approximately 16 feet (5
meters) to the rear.
@® You can recognize the rear bumper in the
lower display.
@ You should stop driving in reverse when the
red orientation line touches the edge of an
object, at the latest.
Symbols
If 2/&9/< is displayed and the display area
represented by that symbol is not available, then
the camera on the that side is not available. The
power exterior mirrors may have been folded in
or a door or the luggage compartment lid may
have been opened.
If # is displayed, there is a system malfunction
and the display area represented by that symbol
is not available. The camera is not working in this
area.
180
If Avis displayed, the respective ultrasonic sensor
is icy or dirty. Clean the area in front of the sen-
sors > page 140.
If one of the symbols continues to be displayed,
drive immediately to an authorized Audi dealer or
authorized Audi Service Facility to have the mal-
function repaired.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 138.
— 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.

() Note
— The orange orientation lines @ show the di-
rection the rear of the vehicle will be travel-
ing, based on the steering wheel angle. The
front of the vehicle swings out more than
the rear of the vehicle. Maintain plenty of
distance so that an exterior mirror or a cor-
ner of the vehicle does not collide with any
obstacles.
— Keep enough distance from the curb to
avoid damage to the rims.
— Only use the images provided by the camera
on the rear of the vehicle when the luggage
compartment lid is completely closed. Make
sure any objects you may have mounted on
the luggage compartment lid do not block
the rearview camera.
G) Tips
Applies to vehicles with air suspension: The
accuracy of the orientation lines and blue sur-
faces on the camera display decreases when
the vehicle is raised or lowered with the air
suspension.

Parking and maneuvering

process will be recalculated based on the vehi-
cle position.
LED in the button (4)
The LED informs about the availability of park as-
sist plus:
— Blinking white - park assist plus is ready to
control the parking process automatically or to
resume after an interruption.
— Green - park assist plus is active.
— Red - park assist plus was paused or stopped. A
message will appear in the instrument cluster
display > page 190.
Indicator in the upper display
The current driving maneuver and the status of
the park assist plus are shown in the upper dis-
play:
@ Path that the vehicle will travel during the
current parking maneuver
@® End point of the current parking maneuver/
direction change
®@ o Park assist plus active
©) Driving direction display
End of the parking process
The parking process will end automatically once
the vehicle has reached the end point in the park-
ing space. After park assist plus finishes parking
successfully, the parking lock will be engaged
and the parking brake will be set.
Pause park assist plus > page 189.


— 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.


Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 138.

— 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.

G) 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 189 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.

AN WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.

() Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.
— Do not install and use snow chains if there is
a malfunction in the air suspension*, be-
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo-
nents can be severely damaged.
@ Tips
When using snow chains, it may be advisable
to limit the ESC > page 116.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 284.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 275, fig. 170.
For example: Tread wear 200, Traction AA, Tem-
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern-
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band C. Those grades represent the tire's
ability to stop on wet pavement as measured un-
der controlled conditions on specified govern-
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
SA.
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate

have the problem corrected.
Continuing to drive on run-flat tires is no
longer possible if:
— There is visible damage to the tires, such as
cracks in the sidewalls
— Strong vibrations are felt while driving, or the
tire begins to smoke due to a strong build-up of
heat
—The tire has been heavily damaged, for example
in an accident. There is a risk that parts of the
tire tread will detach and damage important
vehicle components.
—The Electronic Stabilization Control (ESC) is not
working or is continuously running
— The tire pressure monitoring system is not
working
If it is no longer possible to continue driving de-
spite having run-flat tires, see an authorized Audi
dealer or authorized Audi Service Facility for as-
sistance.


— Avoid full-throttle acceleration, heavy
braking, and fast cornering, because this
increases the risk of an accident.
— The vehicle may become more difficult to
control.
— See an authorized Audi dealer or author-
ized Audi Service Facility for assistance if
the tire is too heavily damaged.
— Have the faulty tires replaced and the rims
checked for damage by an authorized Audi
dealer or authorized Audi Service Facility.
— The driver is responsible for the vehicle, for
correcting the tire pressure, and for replac-
ing faulty parts. Therefore, always adjust
your driving to the current situation.


ZA WARNING
Run-flat tires may only be used on vehicles
that were equipped with them at the factory.
— The vehicle must have suspension designed
for run-flat tires and a factory-installed tire
pressure monitoring system.
— Incorrect use of run-flat tires can lead to ve-
hicle damage or accidents. Contact an au-
thorized Audi dealer or authorized Audi
Service Facility to learn if run-flat tires may
be used on your vehicle and if so, which
ones.
—If run-flat tires are used, they must be in-
stalled on all four wheels. Mixing tire types
is not permitted.
— If you have to drive when the tire pressure is
too low or there is no tire pressure, note the
following:
— Do not drive faster than 50 mph (80 km/h)
because this increases the risk of an acci-
dent. Observe any laws specific to the
country where you are driving.

@) Tips
— Audi Original run-flat tires can be identified
by the “AOE” labeling on the tire sidewall.
— You can use the tire mobility kit* on run-flat
tires > page 305.
