5-1. Before driving
Driving
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-
ing lane changes.
■If the EV system overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the EV system overheating. If the
EV system coolant temperature
gauge indicates that the EV system
is overheating, turn the air condi-
tioning off immediately, leave the
road and stop the vehicle in a safe
place. ( P.549)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift position to P.
WARNING
F o l l o w a l l t h e i n s t r u c t i o n s d e s c r i b e d i n this section. Failure to do so could cause an accident resulting in death
or serious injury.
■Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded. ( P.554)
■Vehicle speed in towing
Observe the legal maximum speeds
for trailer towing.
■Before descending hills or long
declines
Reduce speed and downshift. How- ever, never downshift suddenly while
descending steep or long downhill grades.

Toyota Safety Sense
The Toyota Safety Sense con-
sists of the driving assist sys-
tems and contributes to a safe
and comfortable driving expe-
rience:
WARNING
■Toyota Safety Sense
The Toyota Safety Sense operates under the assumption that the driver will drive safely, and is designed to
help reduce the impact to the occu- pants in a collision and assist the driver under normal driving condi-
tions. As there is a limit to the degree of recognition accuracy and control performance that this system can pro-
vide, do not overly rely on this sys- tem. The driver is solely responsible for paying attention to the vehicle’s
surroundings and driving safely.
■For safe use
●Do not overly rely on this system. The driver is solely responsible for paying attention to the vehicle’s sur-
roundings and driving safely. This system may not operate in all situa-tions and provided assistance is
limited. Over-reliance on this sys- tem to drive the vehicle safely may lead to an accident resulting in
death or serious injury.
●Do not attempt to test the operation
of the system, as it may not operate properly, possibly leading to an accident.
●If attention is necessary while per-forming driving operations or a sys-
tem malfunction occurs, a warning message or warning buzzer will be operated. If a warning message is
displayed on the display, follow the instructions displayed.
●Depending on external noise, the volume of the audio system, etc., it may be difficult to hear the warning
buzzer. Also, depending on the road conditions, it may be difficult to recognize the operation of the sys-
tem.
■When it is necessary to disable
the system
In the following situations, make sure to disable the system.
Failure to do so may lead to the sys- tem not operating properly, possibly leading to an accident resulting in
death or serious injury.
●When the vehicle is tilted due to
being overloaded or having a flat tire
●When driving at extremely high speeds
●When towing another vehicle
●When the vehicle is being trans-
ported by a truck, ship, train, etc.
●When the vehicle is raised on a lift
and the tires are allowed to rotate freely
●When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tes-
ter, or when using an on vehicle wheel balancer
●When the vehicle is driven in a sporty manner or off-road
●When using an automatic car wash

PCS (Pre-Collision Sys-
tem)
The pre-collision system uses
sensors to detect objects
( P.284) in the path of the
vehicle. When the system
determines that the possibility
of a frontal collision with a
detectable obj ect is high, a
warning operates to urge the
driver to take evasive action
and the potential brake pres-
sure is increased to help the
driver avoid the collision. If the
system determines that the
possibility of a collision is
extremely high, the brakes are
automatically applied to help
avoid the collision or help
reduce the impact of the colli-
sion.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.
( P.293)
WARNING
■For safe use
●Driving safely is solely the responsi-
bility of the driver. Pay careful atten- tion to the surrounding conditions in order to ensure safe driving. Never
use the pre-collision system in place of normal braking operations. This system cannot help avoid or
reduce the impact of a collision in every situation. Over-reliance on this system to drive the vehicle
safely may lead to an accident resulting in death or serious injury.

WARNING
■Before using the LTA system
●Do not overly rely on the LTA sys-tem. The LTA system is not a sys-
tem which provides automated assistance in driving and it is not a system which reduces the amount
of attention necessary for safe driv- ing. The driver is solely responsible for paying attention to their sur-
roundings and operating the steer- ing wheel as necessary to ensure safety. Also, the driver is responsi-
ble for taking adequate breaks when fatigued, such as when driv-ing for a long time.
●Failure to perform appropriate driv-ing operations and pay careful
attention may lead to an accident.
●When not using the LTA system,
turn it off using the LTA switch.
