With tire pressures which ar etoo low, there is a risk of the
following hazards:
R they may burst, especially as the load and vehicle speed
increase.

WARNING
Always faste nitems 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, durin ghard 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 cargo compartmentist he preferred place
to carry objects. Always use cargo tie-down
rings, and if so equipped, always use the cargo
net when transporting cargo.
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.
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 load limit and GVWR
are given on the vehicle identification plate
found on the B-pillar of the driver's door
(Y
page 323).
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 relevant GVWR and GAWR
information can be found on the vehicle
identification plate on the B-pillar of the
driver's side (Y page 323).
You will find further information in the
"Loading the vehicle" section (Y page 323).
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:
R when transporting a load, never exceed the
maximum permissible gross vehicle weight
or the gross axle weight rating of the
vehicle (including occupants).
R position heavy loads as far forwards as
possible and as low down in the cargo
compartmenta s possible.
R the load must not protrude above the upper
edge of the seat backrests.
R always place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
R hook in the cargo net when loading.
R always place the load behind unoccupied
seats if possible.
R secure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges
for protection. 250

(OCS)
Do not place objects with a combined weight
of more than 4.4 lbs (2 kg) into the parcel net
on the back of the front passenger seat.
Otherwise, the OCS may not be able to
properly approximate the occupant weight
category. G
WARNING
