grounding conductor is able to result in a risk 
of electric shock. Check with a qualified elec- 
trician or serviceman if you are in doubt as to 
whether the product is properly grounded. Do 
not modify the plug provided with the product 
- if it will not fit the outlet, have a proper out- 
let installed by a qualified electrician. 
Always store the charging equipment securely 
before transporting.

@ Tips 
— The device runs a self test after power has 
been restored to the control unit. If a self 
test is successful, all indicator lights will il- 
luminate green for two seconds. 
— If a household socket is used for the charg- 
ing process, the charging power level is au- 
tomatically set to 100%. If multiple electri- 
cal consumers are connected to a circuit, 
the charging power may be limited to 50% 
when charging with a household socket in 
order to relieve the load on the electrical in- 
stallation. 
— If an industrial socket is used for the charg- 
ing process, the charging power level is au- 
tomatically set to 50%. To receive the maxi- 
mum charging power, the value must be set 
to 100%. 
— The Audi e-tron compact charging system is 
designed for charging at sockets with a volt- 
age of 120 V/240 V.  If your socket has a dif- 
ferent voltage, contact and authorized Audi 
dealer or authorized Audi Service Facility. 
— If your Audi e-tron compact charging sys- 
tem has a fixed connection, meaning can be 
connected directly to the power supply 
without a power cable, contact a qualified 
electrician or an authorized Audi dealer or 
authorized Audi Service Facility.

Trailer towing 
  
The permitted tongue weight of your vehicle can 
be found in the vehicle documentation or in 
=> page 292. 
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 in the vehicle luggage compart- 
ment, if possible. 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 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 253. 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 
The Audi drive select* comfort mode > page 98 
must be selected before you adjust the tongue 
weight on the trailer and hitch the trailer >@, 
=> page 99. 
For vehicles with a retrofitted trailer hitch, you 
must switch on the air suspension trailer mode 
manually. 
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. 
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 99. 
You can also increase ground clearance by select- 
ing the Audi drive select* offroad or allroad 
modes > page 98. 
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.

Assist systems 
  
Assist systems 
General information 
Sica eel delay 
  
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. 
— Unexpected steering or braking interven- 
tions may be initiated by the assist systems. 
Note the information on storing luggage 
items correctly > page 77. 
— 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 124 or > page 125. 
  
    
G) 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 acceler- 
ating 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 if 
another personal profile was used. 
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. 
@) 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 120. 
— If accessories have been mounted on the 
steering wheel, the ability for the steering 
systems to react may be limited.
