Loading
If the backrest is not locked into position,
a red indicator3 will be visible.
Check for secure locking by pushing
and pulling on the backrest.
Loading instructions
The total load weight including vehicle
occupants and luggage/cargo should not
exceed the load limit indicated on the cor-
responding placard located 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.
Warning!G
If a red indicator is visible with the backrest
up, then the backrest is not properly locked
into position.
Always lock backrest in its upright position
when rear seat bench is occupied, cargo is
being carried in the trunk, or the extended
cargo compartment is not in use. Check for
secure locking by pushing and pulling on the
backrest.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and 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.
iTo prevent unauthorized persons from ac-
cess to the trunk, always lock backrest in its up-
right position.

Loading
Always place items being carried against
front or rear seat backrests, and fasten
them as securely as possible.
The heaviest portion of the cargo should al-
ways be kept as low as possible since it in-
fluences the handling characteristics of
the vehicle.Cargo tie-down rings*
The four cargo tie-down rings are located
in the trunk.
Cargo tie-down rings
Carefully secure cargo by applying
even load on all rings with rope
sufficient strength to hold down the
cargo.
Always follow loading instructions
(
page 235).
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, exercise care
when transporting cargo.

carbon monoxide (CO) gases may enter ve-
hicle interior resulting in unconsciousness
