There may be different towbar variants available for the car. Contact a Volvo dealer for more information.
When the car is switched off, the constant battery voltage to the trailer connector can be switched off automatically in order not to drain the starter battery.
The towball needs regular cleaning and lubrication with grease in order to prevent wear.
When a hitch with a vibration damper is used, the towball must not be lubricated.
This also applies when fitting a bicycle rack that is clamped in around the towball.
If the car is equipped with a towbar, there is no rear mounting for a towing eye.
