Grounding instructions
Audi charging systems must be grounded. If it
should malfunction or break down, grounding
provides a path of least resistance for electric
current to reduce the risk of electric shock. Audi
charging systems are equipped with a cord hav-
ing an equipment grounding conductor and a
grounding plug. The plug must be plugged into
an appropriate outlet that is properly installed
and grounded in accordance with all local codes
and ordinances.

Z\ WARNING
Improper connection of the equipment-
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.

Trailer towing


— Note that the vehicle will lower automatical-
ly at certain speeds if you have lifted the

vehicle manually.

@) Note
— Select 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.
— 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 try to
“straighten out” the trailer by accelerating.
122
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.

ZA 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.
