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 Read the information on qualified specialist workshops: (Y page 26).

Stowage areas Loading guidelines G WARNING If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip over or be flung around and thereby hit vehicle occupants. There is a risk of injury, particularly in the event of sudden braking or a sudden change in direction. Always store objects so that they cannot be flung around. Secure objects, luggage or loads against slipping or tipping before the journey. G WARNING Combustion engines emit poisonous exhaust gases such as carbon monoxide. Exhaust gases can enter the vehicle interior if the trunk lid/tailgate is open when the engine is running, especially if the vehicle is in motion. There is a risk of poisoning. Always switch off the engine before opening the trunk lid/tailgate. Never drive with the trunk lid/tailgate open.

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: RNever 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 B-pillar of the driver's door.

RThe trunk/cargo compartment is the

preferred place to store objects.

RPosition heavy loads as far forwards as possible and as low down in the trunk/ cargo compartment as possible.

RThe load must not protrude above the

upper edge of the seat backrests.

RAlways place the load against the rear or front seat backrests. Make sure that the seat backrests are securely locked into place.

RAlways place the load behind unoccupied

seats if possible.

RUse the cargo tie down rings and the parcel

nets to transport loads and luggage.

RUse cargo tie-down rings and fastening materials appropriate for the weight and size of the load.

RWhen transporting objects in the cargo

compartment, the combined cargo cover and net must always be installed (cargo compartment cover and cargo net).

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

Stowage space Important safety notes G WARNING If objects in the passenger compartment are stowed incorrectly, they can slide or be thrown around and hit vehicle occupants.
