Audi Q3: Driving with a trailer

Trailer brakes

If the trailer has its own brake system, then follow the manufacturer specifications. However, the brake system on the trailer must never be connected to the vehicle brake system.

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.


If the trailer is equipped with electronic brakes, these brakes cannot be activated by a factory-installed control system, which increases the risk of an accident.

Retrofit installation

You can find out if your vehicle is equipped with a retrofitted trailer hitch at an authorized Audi dealer or authorized Audi Service Facility.

An authorized Audi dealer or authorized Audi Service Facility knows the specifications for retrofitting a trailer hitch and any necessary technical requirements.


  • Only have the additional trailer hitch installed by an authorized Audi dealer or authorized Audi Service Facility.
  • There is a risk of an accident if the trailer hitch is installed incorrectly.
  • For your own safety, read the assembly instructions provided by the trailer hitch manufacturer.


  • Connecting the socket incorrectly could cause damage to the vehicle electrical system.
  • Longer inclines cannot be driven without a suitable cooling system, especially if the outside temperatures are high. Otherwise, this increases the risk of engine damage.
