CAUTION
■Limitations of the pre-collision system
Do not overly rely on the pre-collision system. Always drive safely, taking
care to observe your surroundings and checking for any obstacles or other
road hazards.
■ Cautions regarding the assist contents of the system
By means of alarms and brake control, the pre-collision system is intended
to assist the driver in avoiding collisions through the process of LOOK-
JUDGE-ACT.
There are limits to the degree of assistance the system can provide, so
please keep in mind the following important points.
● Assisting the driver in watching the road
The pre-collision system is only able to detect obstacles directly in front of
the vehicle, and only within a limited range. It is not a mechanism that
allows careless or inattentive driving, and it is not a system that can assist
the driver in low-visibility conditions. It is still necessary for the driver to
pay close attention to the vehicle’s surroundings.
● Assisting the driver in making correct judgment
When attempting to estimate the likelihood of a collision, the only data
available to the pre-collision system is that from obstacles it has detected
directly in front of the vehicle. Therefore, it is absolutely necessary \
for the
driver to remain vigilant and to determine whether or not there is a possi-
bility of collision in any given situation.
● Assisting the driver in taking action
The pre-collision system’s braking assist feature is designed to help
reduce the severity of a collision, and so only acts when the system has
judged that a collision is unavoidable. This system by itself is not capable
of automatically avoiding a collision or bringing the vehicle to a stop safety.
For this reason, when encountering a dangerous situation the driver must
take direct and immediate action in order to ensure the safety of all
involved.

CAUTION
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effec-
tively:
● Keep the sensor and front grille clean at all times.
Clean the sensor and front grille with a soft cloth so you do not mark or
damage them.
● Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction.
If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by your Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille or surrounding
area.
● Do not modify or paint the sensor and grille cover.

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 distributionCargo 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. 784)

Example based on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are
riding in your vehicle, which ha s a total load capacity of 1660 lb.
(750 kg)
*, the available amount of cargo and luggage load capacity
will be as follows:
1660 lb. - 366 lb. = 1294 lb. (750 kg - 166 kg = 584 kg)
In this condition, if 3 more pa ssengers with the combined weight of
388 lb. (176 kg) get on, the availa ble cargo and luggage load will be
reduced as follows:
1294 lb. - 388 lb. = 906 lb. (584 kg - 176 kg = 408 kg)
*: The capacity weight varies d epending on the vehicle model. ( P. 784)
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 th e 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.
Failing to do so may result in death or serious injury.
●Stow cargo and luggage in the luggage compartment whenever possi-
ble.
●Do not stack anything in the luggage compartment higher than the
seatbacks. Such items may be thrown about and possibly injure peo-
ple 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 as the
item may get under the brake or accelerator pedal and prevent the
pedals from being depressed properly , block the driver’s vision, or hit
the driver or passengers, causing an accident.
• Driver’s feet
• Front passenger or rear seats (when stacking items)
• Instrument panel
• Dashboard
• Auxiliary box or tray that has no lid

CAUTION
■Storage precautions
●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. Otherwise,
they are much more likely to suffer
death or serious bodily injury, in t he event of sudden braking, sudden
swerving or an accident.
■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 con-
trol which may cause death or serious injury.
■Cross rail adjustment
Make sure the cross rails are locked securely by pushing forward and
rearward them.
Failure to do so may cause an unexpected accident.

CAUTION
■When loading cargo
Observe the following precautions:
●Place the cargo so that its weight is distributed evenly between the
front and rear axles.
●If loading long or wide cargo, never exceed the vehicle overall length
or width. (P. 784)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the roof luggage carrier will make the center of grav-
ity of the vehicle higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failure to operate this vehicle correctly
and result in death or serious injury.
●If driving for a long distance, on rough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
●Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo (vehicles with moon roof)
Be careful not to scratch the surface of the moon roof.
