Trailer towing 
  
Trailer towing 
Driving with a trailer 
General information 
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. 
  
Z\ WARNING 
Do not transport any people in a trailer due to 
the risk of fatal injury. 
Technical requirements 
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. 
Engine cooling system 
Driving with a trailer means a higher load on the 
engine and the cooling system. The cooling sys- 
tem must be designed for additional load and 
contain enough coolant > @. 
CG) Note 
Longer inclines cannot be driven without a 
suitable cooling system, especially if the out- 
side temperatures are high. Otherwise, this 
increases the risk of engine damage. 
Operating instructions 
Towing capacity 
Your vehicle can only be operated with class 1 or 
class 2 trailers. 
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 299. 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 
151

Trailer towing 
  
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 128 
must be selected before you adjust the tongue 
weight on the trailer and hitch the trailer >@, 
=> page 130. 
Likewise, the vehicle cannot be raised manually 
using the Raise function > page 130. 
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 130. 
Vehicle levels below the values set in the comfort 
level will no longer be available, even if you are 
lowering the vehicle manually. 
152 
  
Z\ 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. 
() 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. 
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. 
      
— Avoid driving with a trailer during the vehi- 
cle break-in period. 
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.

Trailer towing 
  
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. 
Conventional drive system: Downshift before 
driving on hills to utilize the engine braking ef- 
fect SA. 
Plug-in hybrid drive: reduce the speed and use 
the 
recuperation braking effect > page 118 to re- 
lieve 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. 
Engine coolant temperature 
Pay attention specifically to the coolant tempera- 
ture display when there are high outside temper- 
atures, and when driving on long inclines 
=> page 14. Shift to a higher gear in a timely man- 
ner. 
  
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.

Assist systems 
  
Assist systems 
General information 
Safety precautions 
  
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. 
— Loose objects can be thrown around the ve- 
hicle interior during sudden driving or brak- 
ing maneuvers, which increases the risk of 
an accident. Store objects securely while 
driving. 
— 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 155. 
      
@ 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 accel- 
erating 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. 
154 
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. 
G) 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. 
— The detection of the surrounding area can 
be limited, for example by vehicles driving 
ahead or by rain, snow, heavy spray, or light 
shining into the camera. 
— If accessories have been mounted on the 
steering wheel, the ability for the steering 
systems to react may be limited.
