that these system s are not avail-
able to help protect you in an acci-
dent, which could result in death
or serious injury. Have the vehicle
inspected by you r Toyota dealer
immediately if this occurs.

Driving
brakes too frequently. This
could cause the brakes to
overheat and result in
reduced braking efficiency.
 Due to the added load of the
trailer, your vehicle’s hybrid
system may overheat on hot
days (at temperatures over
85°F [30°C]) when driving up
a long or steep grade. If the
engine coolant temperature
gauge indicates overheating,
immediately turn off the air
conditioning (if in use), pull
your vehicle off the road and
stop in a safe spot. ( P.535)
 Always place wheel blocks
under both the vehicle’s and
the trailer’s wheels when
parking. Apply the parking
brake firmly, and put the
transmission in P. Avoid park-
ing on a slope, but if unavoid-
able, do so only after
performing the following:
1 Apply the brakes and keep
them applied.
2 Have someone place wheel
blocks under both the vehi-
cle’s and trailer’s wheels.
3 When the wheel blocks are in
place, release the brakes
slowly until the blocks absorb
the load.
4 Apply the parking brake
firmly.
5 Shift into P and turn off the
hybrid system. 
When restarting after parking
on a slope:
1 With the transmission in P,
start the hybrid system. Be
sure to keep the brake pedal
pressed.
2 Shift into a forward gear. If
reversing, shift into R.
3 If the parking brake is in man-
ual mode, release the park-
ing brake. ( P.205)
4 Release the brake pedal, and
slowly pull or back away from
the wheel blocks. Stop and
apply the brakes.
5 Have someone retrieve the
blocks.
■Break-in schedule
If your vehicle is new or equipped
with any new power train compo-
nents (such as an engine, transmis-
sion, transfer [4WD models], rear
differential or wheel bearing), Toyota
recommends that y ou do not tow a
trailer until the vehicle has been
driven for over 500 miles (800 km).
After the vehicle has been driven for
over 500 miles (800 km), you can
start towing. However, for the next
500 miles (800 km), drive the vehi-
cle at a speed of less than 50 mph
(80 km/h) when towing a trailer, and
avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle
will require more fr equent mainte-
nance due to the additional load.
(See “Owner’s Warranty Informa-
tion Booklet” or “Scheduled Main-
tenance Guide” / “Owner’s Manual
Supplement”.)
●Retighten the fixing bolts of the
towing ball and bracket after

Driving
■Emergency steering assist
If the system determines that
the possibility of a collision with
a pedestrian is high and that
there is sufficient space for the
vehicle to be steered into within
its lane, and the driver has
begun evasive maneuver or
steering, emergency steering
assist will assist the steering
movements to help enhance the
vehicle stability and for lane
departure prevention. During
operation, the indicator will illu-
minate in green.
■Intersection right/left turn
assistance
If the system determines that
there is a high possibility of a
collision in the following situa-
tions, it will assist with Pre-colli-
sion warning and, if necessary
Pre-collision braking.
Depending on the configuration
of the intersection, it may not be
possible to support.
 When you turn right/left at an
intersection and cross the
path of an oncoming vehicle 
When you turn right/left,
pedestrian is detected in the
forward direction and esti-
mated to enter your vehicle’s
path (bicyclists are not
detected.)
■Suspension control (vehi-
cles with Adaptive Variable
Suspension System)
When the system determines
that the possibility of a frontal
collision is high, the Adaptive
Variable Suspension System
( P.375) will control the damp-
ing force of the shock absorbers
to help maintain an appropriate
vehicle posture.

over the sensor surface, such as in
a heavy rain. When the system
determines that it is normal, the sys-
tem will return to normal.
■Sensor detection information
●The sensor’s detection areas are
limited to the areas around the
vehicle’ front and rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the
object and other factors, the
detection distance may shorten, or
detection may be impossible.
• Detection may be impossible if static objects draw too close to the
sensor.
• There will be a short delay
between static object detection
and display (warning buzzer
sounds). Even at low speeds,
there is a possibilit y that the object
will come within 11.9 in. (30 cm)
before the display is shown and
the warning buzzer sounds.
• It might be difficult to hear the
buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be difficult to hear the sound of this system due to the
buzzers of other systems.
■Objects which the system may
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the follow-
ing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
■Situations in which the system
may not operate properly
Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly
detect objects. Part
icular instances
where this may occur are listed
below.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is froz en. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnormally,
or objects, such as a wall, may not
be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or
other devices which produce ultra-
sonic waves are near the vehicle
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the
sensor.
●When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling
direction, uneven, or waving are in
the detection range.
●Strong wind is blowing
●When driving in inclement weather
