2022 TOYOTA SIENNA HYBRID towing capacity

2184-1. Before driving
For example, if the “XXX”
amount equals 1400 lbs. and
there will be five 150 lb passen-
gers in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs. (1400 -
750 (5  150) = 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 calcu-
lated in Step 4.
(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.220) Cargo capacity
Total load capacity (vehicle
capacity weight) (
P.516)
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
WARNING
■Capacity and distribution
●Do not exceed the maximum
axle weight rating or the total
vehicle weight rating.
●Even if the tota l load of occu-
pant’ weight and the cargo load
is less than the total load capac-
ity, do not ap ply the load
unevenly. Improper loading may
cause deteriorat ion of steering
or braking control which may
cause death or serious injury.
