Controls in detail Loading Always place items being carried against front or rear seat backrests, and fasten them as securely as possible. The heaviest portion of the cargo should always be kept as low as possible since it influences the handling characteristics of the vehicle. Warning! G i The trunk is the preferred place to carry objects. The enlarged cargo area should only be used for items which do not fit in the trunk alone. Always fasten items being carried as securely as possible.

To help avoid personal injury during a collision or sudden maneuver, exercise care when transporting cargo. Never drive vehicle with trunk open. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death. 215
