Important
While driving
Maintain a low speed when driving with a trailer up long, steep ascents.
Avoid driving with a trailer on inclines of more than 12%.
The additional load increases the risk of overheating, which will be indicated in the driver display. Follow any
instructions shown.
Avoid parking on an incline if possible. The extra weight of the trailer can affect the parking brake's ability to
securely hold the car. If you cannot avoid parking on an incline, be sure to block the wheels[1] as a precaution.
Snaking
Snaking is a phenomenon that can occur when towing a trailer. It causes the car and trailer to resonate in a side-to-
side motion, which can escalate quickly and cause loss of control. Snaking primarily occurs at high speeds, especially
if the trailer load is too heavy or improperly distributed. The car continually monitors its movement and can intervene
to help the driver regain control if it detects snaking.
Factors that introduce sideways motion can trigger snaking. For example:
Sudden gusts and powerful side winds.
Uneven road surfaces.
Sweeping steering wheel movements from side to side.
Trailer stability assistance
The stability control system[2] intervenes if it detects snaking when towing a trailer. The system precisely times indi-
vidual braking actions for the front wheels to mitigate the snaking phenomenon. This is often enough to help the
driver stabilise the car and trailer.
When the stability control system intervenes to suppress snaking, the electronic stability control symbol is shown in
the driver display.

Interventions and warnings when reversing
The car can automatically brake to prevent a collision when reversing if it detects an obstacle or crossing traffic behind
the car. Interventions and warnings when reversing are disabled when towing a trailer.
Note
If you've had the towbar installed after purchasing your car, a system update may be needed for the towing features
to work. Contact a Volvo dealer to update the software.
