Setting the charging target 
You can set the charging target, meaning you can 
set the maximum charge level to which the high- 
voltage battery should be charged. The charging 
target can be set between 50% and 100%. For 
daily usage, Audi recommends setting the charg- 
ing target at 80%. This can extend the service life 
of the high-voltage battery. Before long trips, Au- 
di recommends setting the charging target at 
100% for the highest possible range.

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.

Trailer towing 
  
Trailer towing 
Driving with a trailer 
ere eleurl lela) 
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 
Certain requirements must be met when towing 
a trailer. 
      
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. 
120 
  
AN 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. 
Oo} T-Te lalate mie as (olay 
Towing capacity 
       
The permitted towing capacity must not be ex- 
ceeded under any circumstances > page 292. 
You can drive up larger inclines if you are not us- 
ing the maximum towing capacity. 
The towing capacities given only apply to eleva- 
tions up to 3,200 feet (1,000 m) above sea level. 
As the elevation increases, the motor power de- 
creases  due to the decreasing air pressure. This 
reduces the hill climbing ability and towing ca- 
pacity. For every additional 3,200 ft (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. 
Having the tongue weight too low  affects the ve- 
hicle's handling. For driving safety, always using 
the maximum permitted tongue weight is recom- 
mended, but not exceed it. Distributing the cargo 
in the trailer correctly will help to achieve this 
weight. 
You can determine the tongue weight using a 
tongue weight scale, a bathroom scale, or a pub- 
lic weigh station, for example.  

4KE012721BB 
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. 
      
121  

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.
