Useful information

i This Operator's Manual describes all models and all standard and optional equipment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions.

i Please read the information on qualified

specialist workshops (Y page 29).

Loading guidelines

G WARNING Always fasten items being carried as securely as possible. Use cargo tie-down rings and fastening materials appropriate for the weight and size of the load. In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle. This can cause injury to vehicle occupants unless the items are securely fastened in the vehicle. To help avoid personal injury during a collision or sudden maneuver, exercise care when transporting cargo. Do not pile luggage or cargo higher than the seat backrests. The trunk is the preferred place to carry objects. Never drive a vehicle with the trunk open. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death.

The handling characteristics of a laden vehicle are dependent on the distribution of the load within the vehicle. For this reason, you should observe the following notes when transporting a load: Rwhen transporting a load, never exceed the maximum permissible gross vehicle weight or the gross axle weight rating of the

vehicle (including occupants). The values are specified on the vehicle identification plate on the driver's door frame.

Rposition heavy loads as far forwards as

possible and as low down in the trunk as possible.

Rthe load must not protrude above the upper

edge of the seat backrests.

Ralways place the load against the rear seat

backrests.

Ralways place the load behind unoccupied

seats if possible.

Rsecure the load with sufficiently strong and wear-resistant tie-downs. Pad sharp edges for protection.

Stowage areas Stowage space Important safety notes G WARNING To help avoid personal injury during a collision or sudden maneuver, exercise care when storing objects in the vehicle. Put luggage or cargo in the trunk if possible. Do not pile luggage or cargo higher than the seat backrests. Keep compartment lids closed. This will help to prevent stored objects from being thrown about and injuring vehicle occupants during Rbraking Rvehicle maneuvers Ran accident
