Cargo capacity
Total load capacity (vehicle
capacity weight) (P. 536)
When 2 people with the combined weight of A lb. (kg) are riding in
your vehicle, which has a total load capacity (vehicle capacity weight)
of B lb. (kg), the available amount of cargo and luggage load c apacity
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 passengers with the combined weigh t of
D lb. (kg) get on, the availabl e 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 above example, if the number of occupants
increases, the cargo and luggage load will be reduced by an amo unt
that equals the increased weight due to the additional occupant s. In
other words, if an increase in the number of occupants causes a n
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
■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
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed pr operly,
may block the driver’s vision, or may result in items hitting t he driver or
passengers, possibly causing an accident.
●Do not stack anything behind the front seats higher than the se at-
backs.
●Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or rea r seats (when stacking items)
• On the instrument panel
• On the dashboard
• On the auxiliary box or tray that has no lid
●Secure all items in the occupant compartment.
●Never allow anyone to ride in the rear deck. It is not designed for pas-
sengers. They should ride in thei r seats with their seat belts properly
fastened. Otherwise, they are much more likely to suffer death or seri-
ous bodily injury, in the event of sudden braking, sudden swerv ing or
an accident.
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehic le
weight rating.
●Even if the total load of occupant’s weight and the cargo load is less
than the total load capacity, d o not apply the load unevenly. I mproper
loading may cause deterioration of steering or braking control which
may cause death or serious injury.

Vehicle load limits
◆Total load capacity (vehicle capacity weight): P. 536
Total load capacity means the co mbined weight of occupants, cargo
and luggage.
◆Seating capacity
Vehicles with front se parated type seats —
5 occupants (Front 2, Rear 3)
Vehicles with front bench type seat —
6 occupants (Front 3, Rear 3)
Seating capacity means the max imum 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 tota l load capacity.
◆TWR (Trailer Weight Rating): P. 201
TWR means the maximum gross trai ler 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 o f occupants.
■Total load capacity and seating capacity
These details are also described on the tire and loading inform ation label.
(  P. 440)
Vehicle load limits include total load capacity, seating capaci ty,
TWR (Trailer Weight Rati ng) and cargo capacity.

WARNING
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to the tires, but also degrade steering
and braking ability, res ulting in an accident.

Trailer towing
Contact your Toyota dealer for further information about additi onal
requirements such as a towing kit, etc.
Your vehicle is designed primarily as a passenger-and-load-car-
rying vehicle. Towing a trailer can have an adverse impact on
handling, performance, braking, durability, and fuel consump-
tion. For your safety and the safety of others, you must not ov er-
load your vehicle or trailer. You must also ensure that you are
using appropriate towing equipm ent, that the towing equipment
has been installed correctly a nd used properly, and that you
employ the requisite driving habits. (P. 214)
Vehicle-trailer stability and braking performance are affected by
trailer stability, brake performance and setting, trailer brake s,
the hitch and hitch systems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in
accordance with your trailer’s characteristics and operating
conditions.
Toyota warranties do not apply to damage or malfunction
caused by towing a trailer for commercial purposes.

1984-1. Before driving
■GCWR (Gross Combination Weight Rating)
The maximum allowable gross
combination weight. The gross
combination weight is the sum
of the total vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
weight of the trailer being towed
(including the cargo in the
trailer).
■GVWR (Gross Vehicle Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehi-
cle weight is the total weight of
the vehicle. When towing a
trailer, it is the sum of the vehi-
cle weight (including the occu-
pants, cargo and any optional
equipment installed on the vehi-
cle) and the tongue weight.
■GAWR (Gross Axle Weight Rating)
The maximum allowable gross
axle weight. The gross axle
weight is the load placed on
each axle (front and rear).

■TWR (Trailer Weight Rating)
The maximum allowable gross
trailer weight. The gross trailer
weight is the sum of the trailer
weight and the weight of the
cargo in the trailer.
TWR is calculated assuming
base vehicle with one driver,
one front passenger, towing
package (if available), hitch and
hitch systems (if required).
Additional optional equipment, passengers and cargo in the vehicle will
reduce the trailer weight rating so as not to exceed GCWR, GVWR and
GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is r ecommended
to use a trailer with 2 or more axles.
■
Unbraked TWR (Unbraked Trailer Weight Rating)
The trailer weight rating for tow-
ing a trailer without a trailer ser-
vice brake system.
■Tongue Weight
The load placed on the trailer
hitch ball. ( P. 205)
(With brakes)
(Without brakes)

2004-1. Before driving
■Kingpin Weight
The load placed on the 5th
wheel mount or the gooseneck
ball. (P. 2 0 6 )
● The gross trailer weight must never exceed the TWR described in
the table. ( P. 2 0 1 )
● The gross combination weight must never exceed the GCWR
described in the table. ( P. 2 0 1 )
● The gross vehicle weight must
never exceed the GVWR indi-
cated on the Certification Label.
● The gross axle weight on each
axle must never exceed the
GAWR indicated on the Certifi-
cation Label.
● If the gross trailer weight is over the unbraked TWR, trailer s ervice
brakes are required.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway c ontrol
device with sufficient capacity is required.
● If the gross trailer weight is over 5000 lb. (2268 kg), a weigh t distrib-
uting hitch with suffici ent capacity is required.
