Adjusting the charging power level
The control unit automatically recognizes the
voltage and the available current strength. You
can set whether you would like to charge with full
or reduced charging power. The last setting that

was selected will be saved and used again the
next time the vehicle is charged. If multiple
items are connected to the power circuit, the
charging current may be reduced when charging
at a power outlet. This can help to prevent the
electrical equipment from overheating.
Before charging, always check if the charging
power setting that was selected last is still suita-
ble.

ZA WARNING
— Note the warnings for charging > A\ in
Charging on page 112.
— Before switching a cable, always unplug the
power cable from the socket.
— Only change cables in a dry environment.
— The Audi charging system may only be used
as a complete unit consisting of the power
cables, the control unit, and the vehicle ca-
ble. Depending on the country, the total
length of the power cable, control panel and
vehicle cable may be restricted, for example
to 24.6 ft (7.5 m) in the USA. We recom-


mend using only cables approved by Audi.
G) Tips
The power cable with the power connector for
industrial sockets and the Audi charging sys-
tem control unit are designed to work togeth-
er. Changing the power cable to another con-
nector type may reduce the available charging
power of the entire system. Limitations on
the ability to transfer power (current capacity)
depending on the phase and the number of
available phases may affect the available
charging power.

Trailer towing

— 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 258. 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
you are operating the vehicle. Contact an author-
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 101
must be selected before you adjust the tongue
weight on the trailer and hitch the trailer >@,
=> page 102.
The air suspension trailer mode must be switched
on.
Applies to: MMI: Select on the home screen: VE-
HICLE > Settings & Service > Air suspension:
trailer.
Switch it off again when you are no longer towing
a trailer.
For vehicles with a factory-installed trailer hitch,
the air suspension trailer mode will automatically
switch on if you connect the trailer cable to the
socket.
When using carrier systems that are mounted di-
rectly on the trailer hitch ball head, you can also
switch trailer mode off manually.
If you must drive on roads that are in poor condi-
tion, you can raise the vehicle again after hitching
the trailer or after adjusting the tongue weight
=> page 102.
You can also increase ground clearance by select-
ing the Audi drive select* offroad or allroad
modes > page 101.
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
— 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.

CG) 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.

Trailer towing

— 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.
— Having the vehicle inspected between the
inspection intervals is recommended if you
tow a trailer frequently.
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
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.
Reduce the speed and use the recuperation brak-
ing effect > page 92 to relieve the brakes > 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.

Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-

126


formance, increase braking distance, or cause
complete failure of the brake system.

The assist systems analyze the data from various
sensors and cameras installed in the vehicle. Do
not use any assist systems if there is damage to
the vehicle in an area where sensors and cameras
are located or on the vehicle underbody, or if the
vehicle was involved in a collision. The functional-
ity of the sensors and cameras could be impaired,
or they could malfunction. Have an authorized
Audi dealer or authorized Audi Service Facility
check their function.

Radar sensors
Depending on the vehicle equipment, the area
surrounding the entire vehicle may be detected
> fig. 94 ©.
The wheel sensors on the rear corners of the vehi-
cle are positioned so that the adjacent lanes to
the left and right are detected on roads with a
normal lane width.
Ultrasonic sensors
Depending on vehicle equipment, various areas
may be displayed in the MMI using the ultrasonic
sensors > fig. 94.
The range of the displays depends on the location
of the ultrasonic sensors:

passing. There may have been changes to the sur-
rounding area after switching the ignition off and
on again, after opening the doors, or if the vehi-
cle is left stationary for a period of time. In this
case, the area will appear black until the area has
been detected and evaluated.
Cameras
Use the camera image on the display to assist you
only if it shows a good, clear picture. Keep in
mind that the image in the display is enlarged
and distorted. Under certain circumstances, ob-
jects may appear different and unclear on the dis-
play.
The rearview camera can only detect the area
marked in red > fig. 95. Only this area is dis-
played on the upper display > A\.

ZA\ WARNING
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 detected at all.
Always monitor the traffic and the vehicle's >
