Cargo and luggage

Cargo 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 combined 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 the available amount of cargo and lug-

gage 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 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 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. (

P. 162)

Scion does not recommend towing a trailer with your vehicle. Your
vehicle is not designed for trailer towing.

Take notice of the following information about storage precau-
tions, cargo capacity and load:

Capacity and distribution

160

5-1. Before driving

Cargo capacity

Total load capacity (vehicle
capacity weight) (

P. 396)

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 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 2 more passengers 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 luggage 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 number 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.

CAUTION

■

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 properly,
may block the driver’s vision, or may result in items hitting the driver or
passengers, possibly causing an accident.

●

Stow cargo and luggage in the luggage compartment whenever possi-
ble.

●

Do not stack cargo and luggage in the luggage compartment higher
than the seatbacks. 
Such items may be thrown about and possibly injure people in the
vehicle in the event of sudden braking or in an accident.

●

Do not place cargo or luggage in or on the following locations.

• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the instrument panel
• On the dashboard

●

Secure all items in the occupant compartment, as they may shift and
injure someone during sudden braking, sudden swerving or an acci-
dent.

●

When you fold down the rear seats, long items should not be place
directly behind the front seats.

●

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.

■

Capacity and distribution

●

Do not exceed the maximum axle weight rating or the total vehicle
weight rating. 

●

Even if the total load of occupant’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.

Operation of the power switch

●

When operating the power switch, one short, firm press is enough. If the
switch is pressed improperly, the EV system may not start or the power
switch mode may not change. It is not necessary to press and hold the
switch.

●

If attempting to restart the EV system immediately after turning the power
switch off, the EV system may not start in some cases. After turning the
power switch off, please wait a few seconds before restarting the EV sys-
tem.

■

If the smart key system has been deactivated in a customized setting
P. 384

CAUTION

■

When starting the EV system

Always start the EV system while sitting in the driver’s seat. Do not depress
the accelerator pedal while starting the EV system under any circum-
stances.
Doing so may cause an accident resulting in death or serious injury.

■

Caution while driving

If EV system failure occurs while the vehicle is moving, do not lock or open
the doors until the vehicle reaches a safe and complete stop. Activation of
the steering lock in this circumstance may lead to an accident, resulting in
death or serious injury.

■

Stopping the EV system in an emergency

If you want to stop the EV system in an emergency while driving the vehicle,
press and hold the power switch for more than 2 seconds, or press it briefly
3 times or more in succession. (

P. 329)

However, do not touch the power switch while driving except in an emer-
gency. Turning the EV system off while driving will not cause loss of steering
or braking control, but the power assist to these systems will be lost. This
will make it more difficult to steer and brake, so you should pull over and
stop the vehicle as soon as it is safe to do so.

Using regenerative brake

●

When high speed driving, the feeling of deceleration with regenerative brak-
ing is smaller than the deceleration feeling obtained on conventional vehi-
cles.

●

When strong regenerative braking is required, shift the shift lever to S or B. 
Continuously running in S or B can lead to poor power consumption. Drive
normally in D.

●

If “REGENERATIVE BRAKING LIMITED” appears on the multi-information
display, firmly depress the brake pedal to decelerate the vehicle. (
