Opening the stowage compartment in the rear armrest
WARNING Risk of injury due to objects being stowed incorrectly
If you inadequately stow objects in the vehicle interior, they could slip or be tossed around and thereby strike vehicle occupants. In addition, cup holders, open stowage spaces and mobile phone brackets cannot always restrain the objects they contain in the event of an accident.
There is a risk of injury, particularly in the event of sudden braking or a sudden change in direction.
Always stow objects in such a way that they cannot be tossed about in these or similar situations.
Always make sure that objects do not project from stowage spaces, luggage nets or stowage nets.
Close the lockable stowage spaces before starting a journey.
Always stow and secure objects that are heavy, hard, pointed, sharp-edged, fragile or too large in the boot.
Observe the notes on loading the vehicle.
