Driving
WARNING
■Trailer towing precautions
To tow a traile r safely, use
extreme care and drive the vehi-
cle in accordance with the trailer’s
characteristics and operating con-
ditions. Failure to do so could
cause an accident resulting in
death or serious injury. Vehicle
stability and braking performance
are affected by trailer stability,
brake setting and performance,
and the hitch. Your vehicle will
handle differently when towing a
trailer.
■To avoid accident or injury
●Do not exceed the TWR,
unbraked TWR, GCWR, GVWR
or GAWR.
●Vehicles without spare tire: Do
not tow a trailer when the tire
installed is re paired with the
emergency tire puncture repair
kit.
●If the gross trailer weight is over
2000 lb. (907 kg), a sway con-
trol device with sufficient capac-
ity is required.
●Adjust the tongue weight within
the appropriate range. Place
heavier loads as close to the
trailer axle as possible.
●Do not exceed 65 mph (104
km/h), the posted towing speed
limit or the speed limit for your
trailer as set fort h in your trailer
owner’s manual, whichever is
lowest. Slow down sufficiently
before making a turn, in cross
winds, on wet or slippery sur-
face, etc. to help avoid an acci-
dent. If you experience a
vehicle-trailer instability from
reducing a certain speed, slow
down and make sure you keep
your vehicle speed under the
speed of which you experience
the instability.
●Do not make jer ky, abrupt or
sharp turns.
●Do not apply the brakes sud-
denly as you may skid, resulting
in jackknifing and loss of vehicle
control. This is especially true
on wet or slippery surfaces.
●Do not exceed the trailer hitch
assembly weight, gross vehicle
weight, gross axle weight and
trailer tongue w eight capacities.
●Do not use dynamic radar
cruise control with full-speed
range when towing.
●Slow down and downshift
before descending steep or long
downhill grades. Do not make
sudden downshifts while
descending steep or long down-
hill grades.
●Vehicle-trailer in stability is more
likely on steep long downhills.
Before descending steep or
long downhill grades, slow
down and downshift. Do not
make sudden downshifts when
descending steep or long down-
hill grades. Avoid holding the
brake pedal down too long or
applying the brakes too fre-
quently. This could cause the
brakes to overheat and result in
reduced braking efficiency.
●Vehicles with compact spare
tire: Do not tow a trailer when
the compact spare tire is
installed on your vehicle.
■When towing a trailer
Toyota recommends trailers with
brakes that conform to any appli-
cable federal and s tate/provincial
regulations.

Driving
■Enabling/disabling the pre-
collision system
The pre-collision system can be
enabled/disabled on
( P.112) of the multi-informa-
tion display.
The system is automatically
enabled each time the power
switch is turned to ON.
If the system is disabled, the
PCS warning light will turn on
and a message will be displayed
on the multi-information display.
■Changing the pre-collision
warning timing
The pre-collision warning timing
can be changed on
( P.112) of the multi-informa-
tion display.
The warning timing setting is
retained when the power switch is
turned to OFF. However, if the pre-
collision system is disabled and re-
enabled, the operation timing will
return to the default setting (mid-
dle).
WARNING
●When your vehicle is towing
another vehicle
●When transporting the vehicle
via truck, boat, train or similar
means of transportation
●When the vehicle is raised on a
lift with the hybrid system on
and the tires are allowed to
rotate freely
●When inspecting the vehicle
using a drum tester such as a
chassis dynamometer or speed-
ometer tester, or when using an
on vehicle wheel balancer
●When a strong impact is applied
to the front bumper or front
grille, due to a n accident or
other reasons
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When tires of a size other than
specified are installed
●When tire chains are installed
●When a compact spare tire or
an emergency tire puncture
repair kit is used
●If equipment (snow plow, etc.)
that may obstruct the radar sen-
sor or front camera is temporar-
ily installed to the vehicle

2784-5. Using the driving support systems
WARNING
●Vehicle is driven in a construc-
tion zone.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been
excessively worn, or when the
tire inflation pressure is low.
●When your vehicle is towing a
trailer or during emergency tow-
ing
■Preventing LTA system mal-
functions and operations per-
formed by mistake
●Do not modify the headlights or
place stickers, etc. on the sur-
face of the lights.
●Do not modify the suspension
etc. If the suspension etc. needs
to be replaced, contact your
Toyota dealer.

bars, kangaroo bar, etc.).
●If your windshield needs
repairs, contact your Toyota
dealer.
■Conditions in which functions
may not operate properly
In the following situations, the
functions may not operate prop-
erly and the vehicle may depart
from its lane. Drive safely by
always paying careful attention to
your surroundings and operate
the steering wheel to correct the
path of the vehicle without relying
solely on the functions.

play is displayed ( P.283) and
the preceding vehicle changes
lanes. (Your veh icle may follow
the preceding vehicle and also
change lanes.)

play is displayed ( P.283) and
the preceding vehicle is sway-
ing. (Your vehicle may sway
accordingly and depart from the
lane.)

play is displayed ( P.283) and
the preceding vehicle is being
driven extremely close to the
left/right lane line. (Your vehicle
may follow the preceding vehi-
cle and depart from the lane.)
●Vehicle is being driven around a
sharp curve.

■Detection range of the sen-
sors
Approximately 3.3 ft. (100
cm)
Approximately 4.9 ft. (150
cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely clos e to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
■Distance display
When an object is detected by a
sensor, the approximate dis-
tance to the object will be dis-
played on the multi-information
display and audio system
screen. (As the distance to the
object becomes short, the dis-
tance segments may blink.)

to normal after dr iving for a while,
clean the sensors and their sur-
rounding area on the bumpers.)
