th re e bicycles can be transpor ted on the bicycle
ra ck:
R when moun tedby attaching toball head 1,
th e maximum load capacity is 75kg.Up to
th re e bicycles can be transpor ted.
The load capacity is calculated from thewe ight
of the bicycle rack and the bicycle rack load. The
vehicle's handling characteristics change
when a bicycle rack isfitted. The vehicle:
R is heavier
R isrestricted in its accele ration and gradeabil‐
ity
R has an increased braking di stance
This can impair theve hicle's handling character‐
istics. Adapt your driving style accordingly. Drive
carefully and maintain a safe dis tance.
