Gap X: Control value 800 mm +/-5 mm

3.1.4

Decide which side (driver’s or passenger’s side) you want to install the add-on
modules (roof box, bicycle rack, etc.) on and close the cap on the carrier on the
opposite side.
This secures the carrier and prevents it from moving lengthways.

Loosely pre-fitting roof box (520 liter) on the roof transport system

WARNING
Improper loading and installing of the roof transport system or add-on modules
•

Danger of objects falling down

•

Danger of objects sticking out



Load the roof transport system or add-on modules in such a way that the load does not project
over the sides of the roof area.



Select the distances between several add-on modules mounted next to each other so that the
transported items cannot bump against each other during the trip.



Secure load sufficiently to prevent it from shifting during the trip.



Check the roof transport system or add-on modules regularly before each trip and during an
extended trips to make sure they are seated correctly and securely on the vehicle.
CAUTION

Incorrect installation, use or care of the roof box
•

Risk of damage to the roof of the vehicle, tailgate and/or roof box

Installation and Conversion Instructions



Since the roof box is large, it should always be installed and removed from the roof transport
system by two people.



Open the roof box only if the opposite lock is locked.



Remove the roof box from the roof of the vehicle before washing the vehicle in an automatic
car wash.



Keep in mind the new overall vehicle height when driving through tunnels or under low
branches and when driving into parking garages and underpasses.



Clean the roof box using soapy water only (without alcohol, chlorine or ammonia additives);
other substances could attack and damage the surface.



Do not put stickers on the roof box. The adhesive film can dissolve the surface of the roof box
or cause tension cracks.



Occasionally spray the locks of the roof box with a commercially available spray lubricant. The
lubricant must not come into contact with the plastic surface of the roof box.



When opening the rear lid for the first time, ensure that there is sufficient space between the
rear lid and the installed roof box. Move the roof box forward in direction of travel if necessary.
4.1

Decide which side (driver's/passenger's side) you want to install the roof box (520 liter) on.

4.2

Open the cap of the roof transport system
(front/rear) on this side ( Owner's Manual,
section on 'Roof Transport System') and

two sliding blocks are touching the groove in the roof transport system carrier.

4.6

Adjust the position of the last two sliding blocks (T-bolt, M8 x 55) with respect to the groove
in the roof transport system by moving them forward or back.
Push roof box (520 liter) evenly towards the center of the vehicle.
