Cargo and luggage
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) — (Total weight of occ upants)
Steps for Determini ng Correct Load Limit 
(1) Locate the statement “The co mbined 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 t hat
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers fr om
XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo an d lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there wil l 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 loa ded
on the vehicle. That weight may n ot safely exceed the available
cargo and luggage load capac ity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your tra iler will be
transferred to your vehicle. Consult this manual to determine h ow
this reduces the available cargo and luggage load capacity of y our
vehicle. ( P. 242)
Toyota does not recommend towing a trailer with your vehicle. Y our
vehicle is not desig ned for trailer towing.
Take notice of the following information about storage precau-
tions, cargo capacity and load.

●In the situations shown below, the system may not be able to accurately
detect surrounding brightness levels. This may cause the low be ams to
remain on or the high beams to cause problems for pedestrians, vehicles
ahead or other parties. In these cases, manually switch between the high
and low beams.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The front camera is deformed or dirty.
• The front camera temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights , tail lights
or fog lights.
• Vehicles ahead have headlights that are either switched off, d irty, are
changing color, or are not aimed properly.
• When driving through an area of intermittently changing brightness and darkness.
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a w inding
road.
• There is a highly reflective object ahead of the vehicle, such as a sign or
a mirror.
• The back of a vehicle ahead is highly reflective, such as a co ntainer on a
truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched betwe en in
an abnormal manner.
• The driver believes that the high beam may be causing problems or dis-

denly, such as at the entrance or exit of a tunnel
• After the hybrid system has started the vehicle has not been d riven for a
certain amount of time
• While making a left/right turn and for a few seconds after mak ing a left/
right turn
• While driving on a curve and for a few seconds after driving o n a curve

■When the sensor may not be correctly detect ing the vehicle ahead
In the case of the following and depending on the conditions, o perate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types o f vehicles, the
approach warning ( P. 336) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane
● Vehicles with small rear ends (trailers with no load on board, etc.)
● Motorcycles traveling in the same lane
● When water or snow thrown up by the surrounding vehicles hinders the
detecting of the sensor
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage
compartment, etc.)
● Preceding vehicle has an extremely high
ground clearance
