You should place heavy items in the baggage compartment against the backrest and sides.

In the event of a collision, heavy objects that are loaded incorrectly in the baggage compartment can penetrate through the backrest. Lighter objects can also turn into deadly projectiles if they are loose in the car. Therefore you must always ensure the car is loaded correctly.

• Place all objects as low as possible, against the backrest and sides.
• Tightly secure all objects.
• Heavy items should be placed on the floor in the back seat or in the baggage compartment, against the backrest and sides.
• Never place heavy objects above the backrest, even if you have a safety net or grill.
• Use the car's seat belts to secure any items on the back seat.
