Loading instructions
Load distributionThe gross vehicle weight which is the
weight of the vehicle including fuel, tools,
spare wheel, installed accessories, pas-
sengers and luggage/cargo must never
exceed the load limit and Gross Vehicle
Weight Rating (GVWR) for your vehicle as
specified on the placard(s) located on the
driver’s door B-pillar. In addition, the load
must be distributed in such a way so that
the weight on each axle never exceeds the
Gross Axle Weight Rating (GAWR) for the
front and rear axle. The GVWR and GAWR
for your vehicle are indicated on the certi-
fication label which can be found on the
driver’s door B-pillar.The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Please pay attention to and comply with
the following instructions when loading the
vehicle and transporting cargo:
Always place items being carried
against front or rear seat backrests,
and fasten them as securely as possi-
ble.
The heaviest portion of the cargo
should always be kept as low as possi-
ble against front or rear seat backrests.
Warning!
G
Always fasten items being carried as secure-
ly 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 sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, always use parti-
tion net when transporting cargo.
Never drive vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.
