Starting and driving
Loading
General
The load capacity is affected by extra acces-
sories mounted on the car, such as a towbar,
the load on the towball (75 kg with trailer
hitched), load carriers and roof box, as well as
the passengers' combined weight. The load
capacity of the car is reduced by the number
of passengers and their weight.
The car's driving characteristics change
depending on how heavily it is loaded and
how the load is distributed.
NOU
Load on the roof
Load carrier position (accessory)
Make sure the load carrier is placed in the
right direction on the roof rails. Load carriers
can be positioned anywhere along the roof
rails. When driving without a load, the front
load carrier should be positioned 200 mm in
front of the centre rail foot and the rear load
carrier centred between the centre and rear
rail foot (see illustration) to minimise wind
noise. The longer load carrier should be in the
front.
Fitting load carriers
Make sure that the load carrier sits correctly
against the roof rail. Screw on the load carrier
using its torque wrench. Tighten to the
marking on the torque wrench (corresponds
to 6 Nm). See illustration!
