(5) Determine the combined weight of luggage and cargo beingloaded on the vehicle.
That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. ( →P. 1 74 )
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, the available amount of cargo and luggage load capacity
will be as follows:
• With third seats — total load capacity: 1200 lb. (544 kg) 1200 lb. - 366 lb. = 834 lb. (544 kg - 166 kg = 378 kg)
• Without third seats — total load capacity: 1000 lb. (454 kg) 1000 lb. - 366 lb. = 634 lb. (454 kg - 166 kg = 288 kg)

When driving
From this condition, if 3 more passengers with the combined weight of
388 lb. (176 kg) get on, the available cargo and luggage load will be
reduced as follows:
• With third seats 834 lb. - 388 lb. = 446 lb. (378 kg - 176 kg = 202 kg)
• Without third seats 634 lb. - 388 lb. = 246 lb. (288 kg - 176 kg = 112 kg)
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other words, if an increase in the
number of occupants causes an excess of the total load capacity (com-
bined weight of occupants plus cargo and luggage load), you must
reduce the cargo and luggage on your vehicle.
Seating configuration variation
Cargo capacity
Weight of removed third seat
If removing the third seat, 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 third seats)
Third seat weight: Right side — 30.2 lb. (13.7 kg)
Left side — 32.4 lb. (14.7 kg)

CAUTION
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
●Do not place anything on the luggage cover, and do not stack anything in the lug-
gage 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 drive with objects on top of the instrument panel.
They may interfere with the driver’s field of view or move during sharp accelera-
tion or turning, thus impairing the driver’s control of the vehicle. In an accident
they may injure the vehicle occupants.
●Secure all items in the occupant compartment, as they may shift and injure some-
one 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 serious bodily injury or death, in
the event of sudden braking or a collision.
■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 dete-
rioration of steering or braking control which may cause death or serious injury.
■Cross rail adjustment
Make sure the cross rails are locked securely by applying pressure forward and
rearward.
Failure to do so may cause an accident, death or serious injury in the event of emer-
gency braking or a collision.

When driving
CAUTION
■When loading cargo
Observe the following precautions:
●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. 4 1 2 )
●Before driving, make sure the cargo is securely fastened to the roof luggage car-
rier.
●Loading cargo on the roof luggage carrier will raise the vehicle’s center of gravity.
Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt maneu-
vers, otherwise unexpected loss of control or vehicle rollover may occur.
●If driving for a long distance, on rough roads, or at high speeds, stop the vehicle
occasionally during the trip to make sure the cargo remains securely fastened.
●Do not exceed 130 lb. (58 kg) cargo weight on the roof luggage carrier.
NOTICE
■When loading the luggage
Be careful not to scratch the surface of the moon roof.
■Cross rail stoppers
To prevent damage the moon roof, do not remove the cross rail stoppers.

Vehicle load limits
Vehicle load limits include total load capacity, seating capacity, towing
capacity and cargo capacity.
■Total load capacity:
With third seats — 1200 lb. (544 kg)
Without third seats — 1000 lb. (454 kg)
Total load capacity means the combined weight of occupants, cargo
and luggage.
■ Seating capacity:
With third seats — Total 8 (Front 2, Rear 6)
Without third seats — Total 5 (Front 2, Rear 3)
Seating capacity means the maximu m number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
Even if the number of occupants are within the seating capacity, do
not exceed the total load capacity.
■ Towing capacity: 6500 lb. (2948 kg)
Towing capacity means the maximum gross trailer weight (trailer
weight plus its cargo weight) that your vehicle is able to tow.
■ Cargo capacity
Cargo capacity may increase or decrease depending on the weight
and the number of occupants.
