switch mode and the driver’ seat
belt condition. ( P.179)
■Jam protection function (vehi-
cles with driving position mem-
ory)

WARNING
■When adjusting the seat posi-
tion
●Take care when adjusting the
seat position to ensure that
other passengers are not
injured by the moving seat.
●Do not put your hands under the
seat or near the moving parts to
avoid injury.
Fingers or hands may become
jammed in the seat mechanism.

space around the feet so they
do not get stuck.
■Seat adjustment
●To reduce the risk of sliding
under the lap bel t during a colli-
sion, do not recline the seat
more than necessary.
If the seat is too reclined, the lap
belt may slide past the hips and
apply restraint forces directly to
the abdomen, or your neck may
contact the shoulder belt,
increasing the risk of death or
serious injury in the event of an
accident.
Adjustments should not be
made while driving as the seat
may unexpectedly move and
cause the driver to lose control
of the vehicle.
●Manual seat only: After adjust-
ing the seat, make sure that the
seat is locked in position.

DrivingCargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) - (Total weight of occu-
pants)
Steps for Determining Correct
Load Limit 
(1) Locate the statement “The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined
weight of the driver and passen-
gers that will be riding in your
vehicle.
(3) Subtract the combined
weight of the driver and passen-
gers from XXX kg or XXX lbs.
(4) The resulting figure equals
the available amount of cargo
and luggage load capacity.
Cargo and luggage
Take notice of the following
information about storage
precautions, cargo capacity
and load.
WARNING
■Things that must not be car-
ried in the luggage compart-
ment
The following things may cause a
fire if loaded in the luggage com-
partment:
●Receptacles co ntaining gaso-
line
●Aerosol cans
■Storage precautions
Observe the following precau-
tions. Failure to do so may pre-
vent the pedals from being
depressed properly, may block
the driver’s vision, or may result in
items hitting the d river or passen-
gers, possibly causing an acci-
dent.
●Stow cargo and luggage in the
luggage compartment when-
ever possible.
●Do not stack anything in the lug-
gage compartment higher than
the seatbacks.
●Do not place cargo or luggage
in or on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)

event of sudden braking, sud-
den swerving or an accident.
