Get helpWhen a roof box is fitted to your vehicle, it may prevent the rear boot from opening fully.
To check whether the roof box will fit without obstructing your boot, measure the distance from the centre of the front roof bar to the point where the roof meets the boot, as shown in the diagram below.
Your vehicle's measurement must be greater than the minimum distance shown below.
Distance from front bar to boot: >132.4 cm
Only reposition roof bars where permitted by your vehicle and roof-rack fitting instructions.
