2485-1. Before driving
(6) If your vehicle will be towing
a trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.
(P.249)
Toyota does not recommend
towing a trailer with your vehicle.
Your vehicle is not designed for
trailer towing.
Cargo capacity
Total load capacity (vehicle
capacity weight) ( P.600) When 2 people with the com-
bined weight of A lb. (kg) are rid-
ing in your vehicle, which has a
total load capacity (vehicle
capacity weight) of B lb. (kg),
the available amount of cargo
and luggage load capacity will
be C lb. (kg) as follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb.
(kg)
*1: A = Weight of people
*2: B = Total load capacity
*3: C = Available cargo and luggage load
In this condition, if 3 more passen-
gers with the combined weight of D
lb. (kg) get on, the available cargo
and luggage load will be reduced E
lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb.
(kg)
*4: D = Additional weight of people
*5: E = Available cargo and luggage load
As shown in the example above,
if the number of occupants
increases, the cargo and lug-
gage load will be reduced by an
amount that equals the
increased weight due to the
additional occupants. In other
words, if an increase in the num-
ber 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.
WARNING
■Capacity and distribution
●Do not exceed the maximum
axle weight rating or the total
vehicle weight rating.
●Even if the total load of occu-
pant’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 control which may
cause death or serious injury.

■Total load capacity and seating
capacity
These details are also described on
the tire and loading information
label. ( P.532)
Vehicle load limits
Vehicle load limits include
total load capacity, seating
capacity, towing capacity
and cargo capacity.
 Total load capacity (vehicle
capacity weight): P.600
Total load capacity means the
combined weight of occu-
pants, cargo and luggage.
 Seating capacity: P.600
Seating capacity means the
maximum number of occu-
pants whose estimated aver-
age weight is 150 lb. (68 kg)
per person.
 Towing capacity
Toyota does not recommend
towing a trailer with your vehi-
cle.
 Cargo capacity
Cargo capacity may increase
or decrease depending on the
weight and the number of
occupants.
WARNING
■Overloading the vehicle
Do not overload the vehicle. It
may not only cause damage to
the tires, but also degrade steer-
ing and braking ability, resulting in
an accident.

2505-1. Before driving
Trailer towing
Toyota does not recom-
mend towing a trailer with
your vehicle. Toyota also
does not recommend the
installation of a tow hitch or
the use of a tow hitch carrier
for a wheelchair, scooter,
bicycle, etc. Your vehicle is
not designed for trailer tow-
ing or for the use of tow
hitch mounted carriers.
Dinghy towing
Your vehicle is not designed
to be dinghy towed (with 4
wheels on the ground)
behind a motor home.
NOTICE
■To avoid serious damage to
your vehicle
Do not tow your vehicle with 4
wheels on the ground.
