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
●When a sensor is misaligned or
deformed due to a strong impact being applied to the sensor or the area around the sensor
●When accessories which obstruct a sensor or light are temporarily
installed to the vehicle

in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When vehicle lanes are wide, or when driving on the edge of a lane, and the vehicle in an adjacent lane is far away
from your vehicle • When an accessory (such as a bicycle carrier) is installed to the rear of the
vehicle • When there is a significant difference in height between your vehicle and
the vehicle that enters the detection area• Immediately after the Blind Spot Moni-
tor is turned on • When towing with the vehicle
●Instances of the Blind Spot Monitor unnecessarily detecting a vehicle and/or object may increase in the fol-
lowing situations: • When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area • When the distance between your vehi-cle and a guardrail, wall, etc., that
enters the detection area is short • When driving up and down consecu-tive steep inclines, such as hills, dips
in the road, etc. • When vehicle lanes are narrow, or when driving on the edge of a lane,
and a vehicle traveling in a lane other than the adjacent lanes enters the detection area
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
• When the tires are slipping or spinning • When the distance between your vehi-cle and a following vehicle is short
• When an accessory (such as a bicycle carrier) is installed to the rear of the vehicle

*: If equipped
SEA (Safe Exit Assist)*
The Safe Exit Assist is a sys-
tem that uses radar sensors
installed on the inner side of
the rear bumper to help occu-
pants judge if an approaching
vehicle or bicycle may collide
with a door to reduce the pos-
sibility of a collision.
WARNING
■Cautions regarding the use of
the system
●The driver is solely responsible for safe driving. Always drive safely,
taking care to observe your sur- roundings.
●Safe Exit Assist is a supplementary system that, when the vehicle is stopped, informs occupants of the
existence of approaching vehicles and bicycles. As this system alone cannot be used to judge safety,
over-reliance on this system may lead to an accident resulting in death or serious injury.
As the system may not function cor- rectly under certain conditions, visual confirmation of safety with
the passengers’ own eyes and mir- rors is necessary.
