2-5. Driving information
Cargo and luggage
Take notice of the following information about storage precau-
tions, cargo capacity and load:
●Stow cargo and luggage in the luggage compartment whenever
possible.
● Be sure all items are secured in place.
● To maintain vehicle balance while driving, position luggage
evenly within the luggage compartment.
● For better fuel economy, do no t carry unnecessary weight.

Capacity and distributionCargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) - (Total weight of occupants)
Steps for Determining Correct Load Limit 
(1) Locate the statement “The co mbined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehi-
cle’s placard.
(2) Determine the combined weight of the driver and passengers that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will
be five 150 lb passengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 
150) = 650 lbs.)
(5) Determine the combined wei ght of luggage and cargo being
loaded on the vehicle. That weig ht 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. Cons ult this manual to determine how
this reduces the available ca rgo and luggage load capacity of
your vehicle. ( P. 784)

CAUTION
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-

seatbacks. Such items may be thrown about and possibly injure peo-
ple in the vehicle in the event of sudden braking or in an accident.

item may get under the brake or accelerator pedal and prevent the
pedals from being depressed properly , block the driver’s vision, or hit

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information
label. (P. 683)
CAUTION
■Overloading the vehicle
Observe the total load capacity when you load the vehicle. ( P. 784)
Otherwise, it may not only cause damage to the tires, but also degrade
steering and braking ability, resulting in an accident.
Vehicle load limits include total load capacity, seating capacity,
TWR (Trailer Weight Rating) and cargo capacity.
■Total load capacity: ( P. 784)
Total load capacity means the combined weight of occupants, cargo
and luggage.
■ Seating capacity: 7 or 8 occupants (Front 2, Rear 5 or 6)
Seating capacity means the maxi mum number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
■ TWR (Trailer Weight Rating): 3500 lb. (1588 kg)
TWR means the maximum gross tra iler 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.
