Nissan X-Trail e-POWER 2023 Owners Manual
6.11.2.1. When towing a trailer
Depending on the weight of the vehicle and trailer and the steepness of the slope, there may be a tendency for the vehicle to move backwards when starting from a standstill. When this occurs, you can use the parking brake switch in the same way as a conventional lever type parking brake.
Before starting on sloping roads when towing a trailer, be sure to read the following to prevent the vehicle from moving backward unintentionally.
Release the parking brake switch as soon as the e-POWER system is delivering enough torque to the wheels.
