(6) If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Cons ult this manual to determine how
this reduces the available ca rgo and luggage load capacity of
your vehicle. ( P. 542)
Example on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are
riding in your vehicle, which has a total load capacity of 850 lb. (385
kg), the available amount of cargo and luggage load capacity will be
as follows:
850 lb. - 366 lb. = 484 lb. (385 kg -166 kg = 219 kg)
In this condition, if 3 more pa ssengers with the combined weight of
388 lb. (176 kg) get on , the available cargo and luggage load will be
reduced as follows:
484 lb. - 388 lb. = 96 lb. (219 kg - 176 kg = 43 kg)
As shown in the above example, if the number of occupants
increases, the cargo and luggage load will be reduced by an amount
that equals the increased weight du e to the additional occupants. In
other words, if an increase in th e number of occupants causes an
excess of the total load capacity (combined weight of occupants plus
cargo and luggage load), you must reduce the cargo and luggage on
your vehicle.

Seating configuration variationCargo capacity
Weight of the removed second
seat
If removing the second seats, it is possible to load extra cargo equal
to the weight of the removed seats.
(Cargo capacity) = (Total load capacity) - (Total weight of occupants)
+ (Weight of the removed second seats)
Second seats weight:
7-passenger models Right side 61 lb. (28 kg)
Left side 55 lb. (25 kg)
8-passenger models Right side 48 lb. (22 kg)
Left side 48 lb. (22 kg)
Center 52 lb. (24 kg)
CAUTION
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-
ment.
●Receptacles containing gasoline
●Aerosol cans

When driving
CAUTION
■Storage precautions
●Do not stack anything in the luggage compartment higher than the
seatbacks.
Such items may be thrown about and possibly injure people in the
vehicle during sudden braking or in an accident.
●Do not place items in or
on the following locations:
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• Instrument panel
• Dashboard
Items placed in the above locations could get thrown around in the event
of sudden braking or an accident and injure the vehicle occupants.
In addition, items could block the driv er’s field of vision or move during
sharp acceleration or turning. If items move about they may get under
the brake or accelerator pedals, preventing them from being depressed
properly, or hit the driver or passeng ers. In these situations, the driver’s
control of the vehicle could be impaired, causing an accident.
●Secure all items in the occupant compartment, as they may shift and
injure someone during an accident or sudden braking.
●Never allow anyone to ride in the luggage compartment. It is not
designed for passengers. They should ride in their seats with their seat
belts properly fastened. Otherwise, they are much more likely to suffer
death or serious bodily injury, in the event of sudden braking or a colli-
sion.
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
●Even if the total load of occupant's weight and the cargo load is less
than the total load capacity, do not apply the load unevenly.
Improper loading may cause deterioration of steering or braking con-
trol which may cause death or serious injury.

224 2-5. Driving information
CAUTION
■Roof luggage carrier precautions
When you load cargo on the roof luggage carrier, observe the following:
●Place the cargo so that its weight is distributed evenly between the
front and rear axles.
●If loading long or wide cargo, never exceed the vehicle overall length
or width. (P. 542)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the r oof luggage carrier will make the center of the
vehicle gravity higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehicle cor-
rectly.
●If driving for a long distance, on rough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
●Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.
■Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and
rearward them.
Failure to do so may cause an unexpected accident or severe injury in
the event of emergency braking or a collision.
NOTICE
■When loading the luggage
Be careful not to scratch the surface of the moon roof.
