Maintenance and Care -> Wheels for Your Audi A4 4 Door Fifth Generation (2016-2025)

Driving dynamics  
To turn off the ESC, press and hold the but-  
ton for more than three seconds. The and  
  indicator lights turn on.  
integrated systems cannot always prevent  
collisions.  
Accelerate carefully when driving on  
smooth, slippery surfaces such as ice and  
snow. The drive wheels can spin even when  
these control systems are installed and this  
can affect driving stability and increase the  
risk of a collision.  
To completely reactivate the ESC stabilization  
function, press the button again. The indicator  
lights turn off.  
WARNING  
When the ESC is turned off or limited, there  
will be no vehicle stabilization or it will be  
limited. The driving wheels could spin and  
the vehicle could swerve, especially on slick  
or slippery road surfaces, which increases  
the risk of an accident.  
Tips  
The ABS and ASR only function correctly when  
all four wheels have a similar wear condition.  
Different tire sizes can result in a reduction in  
engine power.  
Because of the increased risk of an accident,  
only drive with the ESC turned off or limited  
when it is necessary. Reactivate the ESC as  
soon as possible.  
Operation  
The button (or , depending on the model)  
for controlling the ESC is located in the center  
console in front of the transmission selector. ESC  
turns on automatically when the ignition is  
turned on.  
Tips  
If you select the Audi drive select* offroad  
mode, hill descent assist will turn on.  
If the ESC is limited, turned off, or malfunc-  
tioning, systems with an automatic braking  
intervention function may not be fully avail-  
able.  
Limiting ESC  
In some situations, it may make sense to limit  
the stabilizing function of the ESC so that the  
wheels can spin, for example to rock the vehicle  
to free it when it is stuck or to drive with snow  
chains. The ESC can also be limited to provide  
more sporty driving characteristics with fewer  
stabilizing corrective actions.  
If malfunctions occur in other systems or  
certain driver assistance systems are active,  
the ESC must be turned on by the system.  
The ESC may turn on automatically and can-  
not be operated with the button.  
To limit the ESC, press the button briefly.  
The indicator light will turn on.  
Messages  
To completely reactivate the ESC stabilization  
function, press the button again. The indicator  
light turns off.  
The following messages may appear, depending  
on the vehicle equipment:  
 / Stabilization control (ESC/  
ABS): malfunction! See owner's manual  
When ESC is limited, allroad models switch to  
Offroad mode. All other model versions switch to  
Sport mode. Sport mode is particularly suited for  
driving on an even road surface. Offroad mode is  
designed for uneven terrain or loose ground.  
There is a malfunction in the ABS or EDL. This al-  
so causes the ESC to malfunction. The brakes still  
function with their normal power, but ABS is not  
active.  
Turning off ESC  
Drive to an authorized Audi dealer or authorized  
Audi Service Facility immediately to have the  
malfunction corrected.  
For a more active control of the vehicle where the  
stabilizing functions of the ESC cannot intervene,  
the ESC can be turned off.

Driving dynamics  
If blinks while driving, the ESC is actively reg-  
ulating. Operating noises may occur. If the indica-  
tor light stays on, the ESC has been turned off  
due to system needs. The indicator light turns off  
when the system is fully functional.

Trailer towing  
Distribute the load in the trailer so that the  
heavy objects are as close to the axle as possi-  
ble.  
Trailer towing  
Driving with a trailer  
General information  
Secure objects so that they do not slide.  
Utilize the maximum permitted tongue weight  
if possible.  
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.  
Speed  
Adhere to the legal speed limits. Follow the legal  
regulations that are applicable in the country  
where you are operating the vehicle.  
Driving with a trailer affects the vehicle's energy  
usage, performance, and wear. It also requires  
greater concentration.  
As the speed increases, the driving stability of  
the vehicle and trailer decreases. Therefore you  
should not exceed the maximum legal speed lim-  
it when there are unfavorable road, weather,  
and/or wind conditions. This especially applies  
when driving downhill.  
A retrofitted trailer hitch must be installed ac-  
cording to the instructions provided by the manu-  
facturer ðpage 121.  
WARNING  
Hills  
To reduce the risk of death, do not transport  
any people in a trailer.  
When you start driving uphill or downhill, the ve-  
hicle and trailer may tilt or sway sooner than  
when driving on a level surface. Reduce the speed  
even for only minor swaying movements. Never  
attempt to “straighten out” the vehicle and trail-  
er by accelerating.  
Only use a ball hitch that is approved for  
your vehicle. Using a ball hitch that is not  
approved for your vehicle can result in issues  
such as unstable driving behavior or uncou-  
pling of the trailer and increase the risk of  
an accident. If you have questions, see an  
authorized Audi dealer or authorized Audi  
Service Facility.  
Downshift before driving on hills to utilize the  
engine braking effect ð  
.
Exterior lighting  
Follow the legal regulations for lighting on your  
trailer that are applicable in the country where  
you are operating the vehicle. If necessary, con-  
tact an authorized Audi dealer or authorized Audi  
Service Facility for more information.  
Operating instructions  
Towing capacity  
Your vehicle can only be operated with class 1 or  
class 2 trailers.  
Before you start driving, check all lighting equip-  
ment on the trailer while it is hitched to the vehi-  
cle.  
Load distribution  
Poor cargo load and distribution can negatively  
impact vehicle handling. Load the vehicle and  
trailer based on the following criteria as much as  
possible:  
The headlight range control automatically ad-  
justs the light range of the headlights.  
Exterior mirrors  
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.  
Make sure that you can also observe the traffic  
area behind the vehicle using the exterior mir-  
rors, and use additional exterior mirrors if neces-  
sary. Adjust the additional exterior mirrors so
