bag when not installed. Do not place heavy objects (e.g. crates or
heavy shopping bags) on top of the wind deflector.
& WARNING
• The two rear seats must not be occupied when the wind
deflector is installed.

when the vehicle is moving. -Risk of injury!
0 Note
When you adjust the front seats when the wind deflector is
installed, be careful not to push the backrests into the wind
deflector when reclining the seats or when moving them back. This
