WARNING ■
When adjusting the seat position ●
Take care when adjusting the seat position to ensure that other passengers are not
injured by the moving seat. ●
Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the se at mechanism.●
Make sure to leave enough space around the feet so they do not get stuck. ■
Seat adjustment
To reduce the risk of sliding under the lap be lt during a collision, do not recline the seat
more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shou lder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be made while drivin g as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.

Before towing
Check that the followin g conditions are met:●
Ensure that your vehicle’s tires are properly inflated. ( → P. 717)●
Trailer tires are inflated a ccording to the trailer manufacturer’s recommendation.●
All trailer lights work as required by law. ●
All lights work each time you connect them.●
The trailer ball is set at the proper height for the coupler on the trailer. ●
The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper to ngue weight, overload-
ing, worn suspension, or other possible causes. ●
The trailer cargo is securely loaded. ●
The rear view mirrors conform to all applicable federal, state/provincial or local regula-
tions. If they do not, install rear view mirrors appropriate for towing purposes.■
AVS (adaptive variable suspension system) (if equipped)
The suspension can be switched fo r improvement in driveability. ( → P. 383)No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.

Conditions under which the BSM function may not function correctly ●
The BSM function may not detect vehicles correctly in the following situations:
• When the sensor is misaligned due to a stro ng impact to the sensor or its surround-
ing area
• When mud, snow, ice, a sticke r, etc. is covering the sensor or surrounding area on
the rear bumper
• When driving on a road surf ace that is wet with standi ng water during bad weather,
such as heavy rain, snow, or fog
• When multiple vehicles are approaching wi th only a small gap between each vehicle
• When the distance between your vehicle and a following vehicle is short
• When there is a significant difference in speed between your vehicle and the vehicle
that enters the detection area
• When the difference in speed between your vehicle and another vehicle is changing
• When a vehicle enters a detection area traveling at about the same speed as your
vehicle
• As your vehicle starts from a stop, a vehicle remains in the detection area
• When driving up and down cons ecutive steep inclines, such as hills, dips on 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 towing a trailer (vehicles with towing package)
• When items such as a bicycle carrier are installed on 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 BSM function is turned on ●
Instances of the BSM function unnecessarily detecting a vehicle and/or object may
increase in the following situations:
• When the sensor is misaligned due to a stro ng impact to the sensor or its surround-
ing area
• When the distance between your vehicle and a guardrail, wall, etc. that enters the
detection area is short
• When driving up and down cons ecutive steep inclines, such as hills, dips on the road,
etc.
• When vehicle lanes are narrow, or when driv ing on the edge of a lane, and a vehicle
traveling in a lane other than the ad jacent 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 vehicle and a following vehicle is short
• When a bicycle carrier or other accessory is installed to the rear of the vehicle
• When towing a trailer (vehicles with towing package)

RX450h_RX450hL _U_OM48F85UWARNING ■
Limitations of the Intelligent Clearance Sonar system
Do not overly rely on the system, as doing so may lead to an accident.●
The driver is solely responsi ble for safe driving. Always drive carefully, taking care to
observe your surroundings. The Intelligent Clearance Sonar system is designed to
provide support to lessen the severity of collisions. However, it may not operate in
some situations. ●
The Intelligent Clearance Sonar system is not designed to stop the vehicle com-
pletely. Additionally, even if the system has stopped the vehicle, it is necessary to
depress the brake pedal immediately as brak e control will be canc eled after approxi-
mately 2 seconds. ■
To ensure the Intelligent Clearance Sonar system can operate properly
Observe the following precauti ons regarding the sensors ( → P. 345). Failure to do so
may cause a sensor to not operate pr operly, and may cause an accident.●
Do not modify, disassemble or paint the sensors. ●
Do not replace a sensor with a part other than a genuine part. ●
Do not subject a sensor or its surro unding area to a strong impact.●
Do not damage the sensors, and always keep them clean.
Observe the following precaution s regarding the radar sensors ( → P. 322). Failure to
do so may cause a radar sensor to not op erate properly, and may cause an accident.●
Do not modify, disassemble or paint the sensors. ●
Do not replace a radar sensor with a part other than a genuine part.●
Do not subject a radar sensor or its surrounding area to a strong impact.●
Do not damage the radar sensors, and alwa ys keep the radar sensors and their sur-
rounding area on the bumper clean. ■
Handling the suspension
Do not modify the suspension, as changes to the height or inclinat ion of the vehicle may
prevent the sensors from detecting objects co rrectly or cause the system to not oper-
ate or operate unnecessarily.

394 4-6. Driving tips
RX450h_RX450hL _U_OM48F85U●
Specific design characteristics give it a higher center of gravity than ordinary
passenger cars. This vehicle design feature causes this type of vehicle to be
more likely to rollover. And, utility vehi cles have a significantly higher rollover
rate than other types of vehicles. ●
An advantage of the higher ground cl earance is a better view of the road
allowing you to anticipate problems. ●
It is not designed for cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Therefore, sharp turns at excessive speeds may
cause the vehicle to rollover.Utility vehicle precautions This vehicle belongs to the utility vehicl e class, which has higher ground clear-
ance and narrower tread in relation to the height of its center of gravity.
Utility vehicle feature
WARNING ■
Utility vehicle precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle: ●
In a rollover crash, an unbelted person is si gnificantly more likely to die than a person
wearing a seat belt. Therefore, the driver and all passengers should always fasten
their seat belts. ●
Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or vehicle rollover
causing death or serious injury. ●
Loading cargo on the roof lu ggage carrier will make the ce nter of the vehicle gravity
higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or abrupt
maneuvers, otherwise it may re sult in loss of control or vehicle rollover due to failure
to operate this vehicle correctly. ●
Always slow down in gusty crosswinds. Be cause of its profile and higher center of
gravity, your vehicle is more sensitive to side winds than an ordinary passenger car.
Slowing down will allow you to have better control. ●
Do not drive horizontally across steep slopes . Driving straight up or straight down is
preferred. Your vehicle (or any similar off- road vehicle) can tip over sideways much
more easily than forward or backward.

Put the jack properly in its jack point. ●
Do not put any part of your body under the vehicle while it is supported by the jack.●
Do not start the hybrid system or drive th e vehicle while the vehicle is supported by
the jack. ●
Do not raise the vehicle while someone is inside. ●
When raising the vehicle, do not pu t an object on or under the jack.●
Do not raise the vehicle to a height greater than that required to replace the tire. ●
