Warning indicators

The warning indicators show the distance
between the sensor and the obstacle. The
warning indicators for the front area are lo-
cated above the center air vents in the
dashboard. The warning indicator for the
rear area is located in the rear passenger
compartment lamp.

1 Segments, left side of vehicle
2 Segments, right side of vehicle

Each warning indicator has six yellow and
two red segments.

The gear selector lever position deter-
mines which warning indicator is activat-
ed.

As soon as the sensors detect an obstacle,
one or more segments light up, depending
on the distance. An intermittent acoustic
warning will also sound as the seventh seg-
ment comes on and a constant acoustic
warning lasting a maximum of
three seconds will sound for the eighth
segment.

Loading

Loading instructions

The 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 Gross Vehicle Weight Rating
(GVWR) for your vehicle. 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
certification label which can be found on
the left door 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:

앫

Always place items being carried
against front or rear seat backrests,
and fasten them as securely as possi-
ble.

앫

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 liftgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.

Loading

For additional safety when transporting
cargo while the rear seats are unoccupied,
fasten the outer seat belts crosswise into
the opposite side buckles.

Cargo tie-down rings

The cargo area is provided with four
tie-down rings. Additional two rings are lo-
cated at the rear of front seats.

Cargo tie-down ring

Carefully secure cargo by applying even
load on all rings with rope of sufficient
strength to hold down the cargo.

i

The cargo area is the preferred place to
carry objects. The enlarged cargo area
should only be used for items which do
not fit in the cargo area alone.

i

While the partition net* (

컄

page 159)

will help protect you from smaller ob-
jects, it cannot prevent the movement
of large, heavier objects into the pas-
senger area in an accident. Such items
must be properly secured using the
cargo tie-down rings in the cargo area
floor.
