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

1944-1. Before driving
Owners Manual_USA_M0C031_enapproximately 600 miles (1000
km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds,
passing vehicles, rough roads, etc.)
can adversely affect handling of
your vehicle and trailer, causing
instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead. Do not try to
control trailer swaying by turning
the steering wheel.
• Begin releasing the accelerator
pedal immediately but very gradu-
ally to reduce speed. Do not
increase speed. Do not apply
vehicle brakes.
If you make no ext reme correction
with the steering or brakes, your
vehicle and trailer should stabilize.
(if enabled, Trailer Sway Control can
also help to stabilize the vehicle and
trailer.)
●After the trailer swaying has
stopped:
• Stop in a safe place. Get all occu-
pants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer. Make sure the load has not shifted.
Make sure the tongue weight is
appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not over-
loaded after occupants get in.
If you cannot find any problems, the
speed at which trailer swaying
occurred is beyond the limit of your
particular vehicle- trailer combina-
tion. Drive at a lower speed to pre-
vent instability. Remember that
swaying of the towing vehicle-trailer
increases as speed increases.
Dinghy towing
Your vehicle is not designed
to be dinghy towed (with 4
wheels on the ground)
behind a motor home.
NOTICE
■To avoid serious damage to
your vehicle
Do not tow your vehicle with the
four wheels on the ground.

The system can detect the fol-
lowing (The detectable objects
differs depending on the func-
tion.):
Vehicles
 Bicyclists 
Pedestrians
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
“BRAKE!”
■Pre-collision brake assist
When the system determines
that the possibility of a frontal
collision is high, the system
applies greater braking force in
relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
If the system determines that
the possibility of a frontal colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.230) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion with an object is high, a
warning operates to urge
the driver to take evasive
action and the potential
brake pressure is increased
to help the driver avoid the
collision. If the system
determines that the possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.234)

due to road repairs
• When a pedestrian is detected near the centerline of the vehicle
• When the target is too close
• When there is insufficient safe or
unobstructed space for the vehicle
to be steered into
• If oncoming vehicle is present
• If VSC function is operating
●In some situations such as the fol-
lowing, sufficient braking force or
steering force may not be
obtained, preventing the system
from performing properly:
• If the braking functions cannot
operate to their full extent, such as
when the brake parts are
extremely cold, extremely hot, or
wet
• If the vehicle is not properly main- tained (brakes or tires are exces-
sively worn, improper tire inflation
pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery
surface
• When the road surface has deep wheel tracks • When driving
on a hill road
• When driving on a road that has inclines to the left or right
• When your vehicles is towing a trailer or ano ther vehicle
• When your vehic le is lifted up
■If VSC is disabled
●If VSC is disabled ( P.376), the
pre-collision brak e assist and pre-
collision braking functions are also
disabled.
●The PCS warning light will turn on
and “VSC Turned OFF Pre-Colli-
sion Brake System Unavailable”

Driving
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system
control continues to keep your vehicle stopped.
When the turn signal lever is ope rated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehi cle will accel-
erate to help to overt ake a passing vehicle.
The system’s identification of what is an overtaking lane may be determined
solely based on the location of the steering wheel in the vehicle (left side
driver position versus right side driver position.) If the vehi cle is driven to a
region where the overtaking lane is on a different side from wh ere the vehi-
cle is normally driven, the vehicle may accelerate when the tur n signal lever
is operated in the opposite direction to the overtaking lane (e .g., if the driver
normally operates the vehicle in a region where the overtaking lane is to the
right but then drives to a region where the overtaking lane is to the left, the
