Vehicle load limits include total load
capacity, seating capacity, towing ca-
pacity and cargo capacity. Follow the
load limits shown below. Total load ca-
pacity and seating capacity are also
described on the tire and loading in-
formation label. For location of the tire
and loading information label, see
“Checking tire inflat ion pr es s ur e” on
page 487.
Total load capacity
Total load capacity means combined
weight of occupants, cargo and lug-
gage. Tongue load is included when
trailer towing. For the total load ca-
pacity about your vehicle, see “Total
load capacity” on page 513 in Section
8.
Seating capacity:
7−passenger models—
Total 7 (Front 2, Rear 5)
8 −passenger models—
Total 8 (Front 2, Rear 6) Seating capacity means the maximum
number of occupants whose esti-
mated average weight is 68 kg (150
lb.) per person. Depending on the
weight of each person, the seating ca-
pacity given may exceed the total
load capacity.
NOTICE
Even if the number of occupants are
within the seating capacity, do not ex-
ceed the total load capacity.
Towing capacity:
1587 kg (3500 Ib.)
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 de-
crease depending on the size (weight)
and the number of occupants. For de-
tails, see “Capacity and distribution”
that follows.
CAUTION
Do not apply the load more than
each load limit. That may cause
not only damage to the tires, but
also deterioration to the steering
ability and braking ability, which
may cause an accident.

When stowing cargo and luggage in
the vehicle, observe the following: Put cargo and luggage in the lug-
gage compartment when at all
possible. Be sure all items are se-
cured in place.
 Be careful to keep the vehicle bal-
anced. Locating the weight as far
forward as possible helps maintain
balance.
 For better fuel economy, do not
carry unneeded weight.
CAUTION
To prevent cargo and l uggage
from sliding forward during
braking, do not stack anything
in the luggage compartment
higher than the seatbacks.
Keep cargo and luggage low,
as close to the floor as pos-
sible.
 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 seri-
ous bodily injury, in the event
of sudden braking or a colli-
sion.
 Do not drive with objects left
on top of the instrument panel.
They may interfere with the
driver’s field of view. Or they
may move during sharp vehicle
acceleration or turning, and im-
pair the driver’s control of the
vehicle. In an accident they
may injure the vehicle occu-
pants.Cargo capacity depends on the to-
tal weight of the occupants.
(Cargo capacity) = (Total load capac-
ity) – (Total weight of occupants)
Steps for Determining Correct
Load Limit—
(1) Locate the statement “The com-
bined 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 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 theavailable amount of cargo and
luggage load capacity. For exam-
ple, if the “ XXX” amount equals
1400 lbs. and there will be five
150 lb passengers in your ve-
hicle, the amount of available
cargo and luggage load capacity
is 650 lbs. (1400–750
(5x150)=650 lbs.)
(5) Determine the combined weight of luggage and cargo being
loaded 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.
For details about trailer towing, see
page 422.

Example on Your Vehicle
In case that 2 people with the com-
bined weight of A kg (lb.) are riding
in your vehicle with the total load ca-
pacity of B kg (lb.), the available
amount of cargo and luggage load ca-
pacity will be C kg (lb.) as follows:
B kg (lb. ) – A kg (lb. ) = C kg (lb. )
From this condition, if 3 more passen-
gers with the combined weight of D
kg (lb.) get on, the available cargo
and luggage load will be reduced E
kg (lb.) as follows:
C kg (lb. ) – D kg (lb. ) = E kg (lb. ) As shown in the above example, if the
number of occupants increases, the
cargo and luggage load equaling the
combined weight of occupants who
got on later must be reduced. In other
words, if the incr
ease in the number
of occupants causes the excess of
the total load capacity (combined
weight of occupants plus cargo and
luggage load), you have to reduce the
cargo and luggage on your vehicle.
For details about total load capacity,
see “Vehicle load limits” on page 411.

CAUTION
Even if the total load of occu-
pant’s weight and the cargo load
is less than the total load capac-
ity, do not apply the load uneven-
ly. That may cause not only dam-
age to the tire but also deteriora-
tion to the steering ability due to
unbalance of the vehicle, causing
an accident.

SEATING CONFIGURATION
VARIATION
In case of removing the second seats,
it is possible to load as much cargo
as the weight of the removed seats.
(Cargo capacity) = (Total load capac-
ity) − (Total weight of occupants) +
(Weight of the removed second seats) Second seats weights:
7−passenger models—
Right side 28 kg (61 lb.)
Left side 25 kg (55 lb.)
8 −passenger models—
Right side 22 kg (48 lb.)
Left side 22 kg (48 lb.)
Center 24 kg (52 lb.)

Determine what kind of tires your
vehicle is originally equipped with.1. Summer tires
Summer tires are high −speed capabil-
ity tires best suited to highway driving
under dry conditions.
Since summer tires do not have the
same traction performance as snow
tires, summer tires are inadequate for
driving on snow −covered or icy roads.
For driving on snow −covered or icy
roads, we recommend using snow
tires. If installing snow tires, be sure
to replace all four tires.
2. All season tires
All season tires are designed to pro-
vide better traction in snow and to be
adequate for driving in most winter
conditions, as well as for use all year
round. All season tires, however, do not have
adequate traction performance
compared with snow tires in heavy or
loose snow. Also, all season tires fall
short in acceleration and handling
performance compared with summer
tires in highway driving.
The details about how to distinguish
summer tires from all season tires are
described on page 401.
CAUTION

Do not mix summer and all sea-
son tires on your vehicle as
this can cause dangerous han-
dling characteristics, resulting
in loss of control.
 Do not use tires other than the
manufacturer’s designated
tires, and never mix tires or
wheels of the sizes different
from the originally equipped
tires and wheels.
