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.

WARNING
Always fasten items being carried as securely
as possible using 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.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death. Driving, braking and steering characteristics
change depending on:
R
type of load
R weight
R the center of gravity of the load
You should therefore load your vehicle as
shown in the illustrations.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle
occupants and luggage/cargo.
The gross load limit and the gross vehicle
weight rating (GVWR) for your vehicle must
never be exceeded. The gross load limit and
the GVWR are specified on the vehicle
identification plate on the B-pillar of the
driver's door (Y page 258).
The load must also be distributed so that the
weight on each axle never exceeds the gross
axle weight rating (GAWR) for the front and
rear axles. The specifications for GVWR and
GAWR are on the vehicle identification plate
on the B-pillar of the driver's door
(Y page 258).
Further information can be found in the
"Loading the vehicle" section ( Ypage 237).
Observe the following notes when
transporting a load:
R Position heavy loads as far forwards as
possible and as low down in the cargo
compartment as possible.
i Transport loads when possible in the
cargo compartment. You should only use
the cargo compartment enlargement if the
load does not fit in the cargo compartment.
R Always place the load against the front or
rear seat backrests. 184
