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. 329)
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.

5-3. Operating the lights and wipers
●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 camera sensor is deformed or dirty.
• The camera sensor 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-
tress to other drivers or pedestrians nearby.

• When there are patterns or paint on the road or a wall that may be mis- taken for a vehicle or pedestrian
• When driving near an object that reflects radio waves, such as a large
truck or guardrail
• When driving near a TV tower, broadcasting station, electric power plant, or other location where strong radio waves or electrical noise may be
present
■ Situations in which the syst em may not operate properly
● In some situations such as the following, a vehicle may not be detected by
the radar sensor and camera sensor, preventing the system from operating
properly:
• If an oncoming vehicle is approaching your vehicle
• If a vehicle ahead is a motorcycle or bicycle
• When approaching the side or front of a vehicle
• If a preceding vehicle has a small rear end, such as an unload ed truck
• When passing under an object (bill-
board, etc.) at the top of an uphill road
• When driving through or under objects that may contact the vehicle,
such as thick grass, tree branches, or
a banner
• If a preceding vehicle has a low rear end, such as a low bed trailer

■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. 409) will 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
