Driving with a trailer always requires extra care and consideration.
Weight distribution
Towing a loaded trailer with an empty car results in a highly unstable distribution of weight. If this cannot be avoided, drive at very low speeds only to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle should be loaded to the extent possible and permissible, while keeping the trailer as light as possible under the circumstances. Whenever possible, transfer some cargo to the luggage compartment of the tow vehicle while observing tongue load requirements and vehicle loading considerations.
Speed
The higher the speed, the more difficult it becomes for the driver to control the rig. Do not drive at the maximum permissible speed. Reduce your speed even more if load, weather or wind conditions are unfavorable - particularly when going downhill.
Reduce vehicle speed immediately if the trailer shows the slightest sign of swaying. Do not try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for vehicles towing trailers are lower than for regular vehicles.
Always apply brakes early. When driving downhill, shift into a lower gear to use the engine braking effect to slow the vehicle. Use of the brakes alone can cause them to overheat and fail.
Air suspension
When driving with a trailer, activate the trailer mode of the air suspension. Switch the air suspension trailer mode on when you are towing a trailer. This will limit the regulation by the air suspension while driving. Select in the MMI: function button > (Car) systems control button > Vehicle settings > Air susp.: towing > On.
Coolant temperature
The coolant temperature gauge must be observed carefully. The coolant temperature can increase if you drive on long inclines in a low gear at high engine speeds. Reduce your speed immediately if the LEDs in the top part of the display turn on.
WARNING
Anyone not properly restrained in a moving vehicle is at a much greater risk in an accident.
Never let anyone ride in your car who is not properly wearing the restraints provided by Audi.
