Roof drip rail with flaps
The anchorage points are located in the roof
drip rail above the doors.
Fold the cover outward.
Loading
Be sure that adequate clearance is maintained
for tilting and opening the glass sunroof.
Because roof racks raise the vehicle's center
of gravity when loaded, they have a major ef‐
fect on vehicle handling and steering re‐
sponse.
Therefore, note the following when loading
and driving:
▷ Do not exceed the approved roof/axle
loads and the approved gross vehicle
weight.
▷ Distribute the roof load uniformly.
▷ The roof load should not be too large in
area.
▷ Always place the heaviest pieces on the
bottom.
▷ Secure the roof luggage firmly, e.g., tie
with ratchet straps.
▷ Do not let objects project into the opening
path of the trunk lid.
▷ Drive cautiously and avoid sudden acceler‐
ation and braking maneuvers. Take corners
gently.
