280 Controls in detailLoadingThe 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.
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*
Four rings1 are located in the trunk.
Carefully secure cargo by applying
even load on all rings with rope of suffi-
cient strength to hold down the cargo.
Always follow loading instructions
(page 279).
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. Put luggage or car-
go in the trunk if possible. Do not pile lug-
gage or cargo higher than the seat backs.
Do not place anything on the rear-window
shelf.
Never drive vehicle with trunk open. Deadly
carbon monoxide (CO) gases may enter ve-
hicle interior resulting in unconsciousness

The lighter socket can be used to accommo-
date 12 V DC electrical accessories (up to a
maximum of 85 W) designed for use with the
standard “cigarette lighter” plug type. Keep in
mind, however, that connecting accessories to
the lighter socket (for example extensive con-
necting and disconnecting, or using plugs that do
not fit properly) can damage the lighter socket.
With the socket damaged, the lighter may no
longer be able to be placed in the heating
(pushed-in) position, or the lighter may pop out
too early with the lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12 V DC
electrical accessories designed for use with a
standard “cigarette lighter” plug type to the 12 V
power outlets in your vehicle whenever possible.
i
The power outlet can be used to
accommodate 12 V DC electrical accessories
(e.g. air pump, auxiliary lamps) up to a maximum
of 180 W.
An additional power outlet is located on the left
side in the trunk.
