How do I drive safely with a roof box mounted?
A roof box doesn't only mean a great deal of additional space. It also means adapting your way of driving to the new conditions resulting from your car's increased height and weight. Your car will be more sensitive to crosswinds. Check whether the roof box and the load carrier are correctly fastened to the car – especially important during long journeys. In the absence of any existing speed restriction, we recommend a maximum speed of 130 km/h (85 mph). A loaded box causes a shift in the centre of gravity which leads to changes in behaviour in curves and when braking. The height of the vehicle is increased by up to 60 cm! Take care in the event of driving through low garage doorways or low bridges!
How do I load a Thule roof box?
First load the heavy objects as centrally as possible in order to distribute the weight of your load evenly on the load carrier and the car. Take care that the load does not obstruct the closing of the lid in order to prevent any malfunctioning of the locking system. The permissible gross vehicle weight may not be exceeded. Observe the maximum roof load prescribed by the car manufacturer. All pieces of baggage must be secured to prevent them from moving. Please use special ski holders and straps. Always fasten skis and snowboards to the ski holders with the front ends pointing to the rear. In summer the ski holders can be used as compartment dividers. They prevent objects from moving and are practical anyway, e.g. for separating clean objects from dirty ones. Provide luggage which should not get damp with an additional protection (e.g. plastic bags).
What about roof box maintenance?
The roofbox should be carefully cleaned and maintained, particularly during the winter months. For this purpose, only use a solution of water and standard washing-up liquid without any alcohol, bleach or ammonium additives as otherwise the surface of the roofbox could suffer damage. Please do not use any standard car cockpit sprays. The locks should be lubricated with spray lubricant (no lubricant should be allowed to come into contact with the plastic surface of the roofbox).
What special details to be followed when using a roof box?
– The height of the given vehicle can increase by up to 70 cm (depending
on the roof rack used)
– Beware of low garage entrances, low clearances in general, low-hanging
– Wind noise may be generated.
– When using an automatic car-wash facility, the roofbox and roof rack
must first be removed.
– For reasons of fuel economy, the roofbox and roof rack can be removed when not in use.
– In order to avoid generating excessive lifting forces, the roofbox should be mounted parallel to the line of the road and not at an angle.
– In the absence of any instructions from the vehicle manufacturer to the contrary and in compliance with the vehicle specifics, the distance between the rack’s transverse struts should be as large as possible but still within the setting range of the adjustable mounting system. Please note that changes (e.g. additional drill holes) to the roofbox’s fixing system are not permitted.
