The steel grid consists of the grid itself and two separate mounting brackets. Each of the mount- ing brackets has a screw cover and two plasticsleeves for the grid.
WARNING
The steel cargo grid may only be used in the rear position described here. The ceilingattachment points behind the front seats arenot intended to anchor the steel grid.

Installation1. Fold down the rear seats and lift in the steel
grid through one of the rear doors or the tail- gate. The curved (convex) side of the gridshould face toward the cargo compartmentand the hooks on each side of the gridshould face upward. The mounting bracketsand plastic sleeves are not needed in thisstep.
2. Press one of the grid's hooks into the largerhole in the ceiling attachment point (1). Grasp the grid near the hook and pull/push it into the smaller hole (2).
> The hook is now secured in the attach-ment point.

Data transfer between vehicle andworkshop over Wi-Fi
Volvo workshops have a designated Wi-Fi net- work for secure data transfer between your vehi-cle and the workshop. Your visit to the workshopwill be easier and more effective when diagnos-tics information and software can be transferredover the workshop's network.
When you arrive at the workshop, your technician can connect your vehicle to the workshop's Wi-Finetwork to perform troubleshooting and down-load software. For this type of communication,the vehicle only connects to the workshop's net-work. The vehicle can only be connected to thedesignated workshop networks, not to any othernetwork, e.g. your home network.
Manual connection to workshop Wi-FiManual connection is usually performed by aservice technician. Because the technician usesthe buttons on your remote key to connect thevehicle, it is important that you bring a key withbuttons when taking the vehicle in to a workshop.Pressing the lock button on the remote key threetimes will connect the vehicle to the workshop'sWi-Fi network. When the car is connected to a Wi-Fi network, the
symbol appears in the center display.
