CAUTION
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
● The Blind Spot Monitor function is a supplementary function which alerts
the driver that a vehicle is present in the blind spot. Do not overly rely on
the Blind Spot Monitor function. The function cannot judge if it is safe to
change lanes, therefore over reliance could cause an accident resulting in
death or serious injury.
● The Rear Cross Traffic Alert function is only an assist and is not a replace-
ment for careful driving. Driver must be careful when backing up, even
when using Rear Cross Traffic Alert function. The driver’s own visual con-
firmation of behind you and your vehicle is necessary and be sure there
are no pedestrians, other vehicles etc. before backing up. Failure to do\
so
could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore
the driver’s own visual confirmation of safety is necessary.

CAUTION
■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of the
vehicle rear bumper respectively. Observe the following to ensure the Blind
Spot Monitor system can function correctly.
● Do not subject the sensor or surrounding area on the bumper to a strong
impact. If the sensor moves even slightly off position, the system may mal-
function and vehicles that enter the detection area may not be detected. If
the sensor or surrounding area is subject to a strong impact, always have
the area inspected by your Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
● Do not modify the sensor or surrounding area on the bumper.
● Do not paint the sensor or surrounding area on the bumper.
●Keep the sensor and its surrounding
area on the bumper clean at all times.

2-5. Driving information
Cargo and luggage
Take notice of the following information about storage precau-
tions, cargo capacity and load:
●Stow cargo and luggage in the luggage compartment whenever
possible.
● Be sure all items are secured in place.
● To maintain vehicle balance while driving, position luggage
evenly within the luggage compartment.
● For better fuel economy, do no t carry unnecessary weight.

Capacity and distribution
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 co mbined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehi-
cle’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 luggage 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 avail-
able cargo and luggage load capacity is 650 lbs. (1400 - 750 (5 
150) = 650 lbs.)
(5) Determine the combined wei ght of luggage and cargo being
loaded on the vehicle. That weig ht 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. Cons ult this manual to determine how
this reduces the available ca rgo and luggage load capacity of
your vehicle. ( P. 800)

Calculation formula for your vehicleCargo capacity
Total load capacity (vehicle
capacity weight) (P. 800)
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 3 more pa ssengers with the combined weight of
D lb. (kg) get on, the available ca rgo 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 du e 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.
