Your vehicle will handle differently when towing a trailer. Help to avoid an acci-
dent, death or serious injury, keep the following in mind when towing:
●Speed limits for towing a trailer vary by state or province. Do not exceed the
posted towing speed limit.
●Lexus recommends that the vehicle-traile r speed limit is 65 mph (104 km/h)
on a flat, straight, dry road. Do not exce ed this limit, the posted towing speed
limit or the speed limit for your trailer as set forth in your trailer owner’s man-
ual, whichever is lowest. Instability of the towing vehicle-trailer combination
(trailer sway) increases as speed increases. Exceeding speed limits may cause
loss of control.
●Before starting out, check the trailer lights, tires and the vehicle-trailer con-
nections. Recheck after driving a short distance.
●Practice turning, stopping and reversing with the trailer attached in an area
away from traffic until you become acc ustomed to the feel of the vehicle-
trailer combination.
●Reversing with a trailer attached is di fficult and requires practice. Grip the
bottom of the steering wheel and move your hand to the left to move the
trailer to the left. Move your hand to the right to move the trailer to right. (This
is generally opposite to reversing with out a trailer attached.) Avoid sharp or
prolonged turning. Have someone guid e you when reversing to reduce the
risk of an accident.
●As stopping distance is increased when towing a trailer, vehicle-to vehicle dis-
tance should be increased. For each 10 mph (16 km/h) of speed, allow at least
one vehicle and trailer length.
●Avoid sudden braking as you may skid, resulting in the trailer jackknifing and a
loss of vehicle control. This is especi ally true on wet or slippery surfaces.
●Avoid jerky starts or sudden acceleration.
●Avoid jerky steering and sharp turns, an d slow down before making a turn.
●Note that when making a turn, the trailer wheels will be closer than the vehicle
wheels to the inside of the turn. Compensate by making a wider than normal
turning radius.
●Slow down before making a turn, in cross winds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer.
●Take care when passing other vehicles . Passing requires considerable dis-
tance. After passing a vehicle, do not fo rget the length of your trailer, and be
sure you have plenty of room before changing lanes.

The pre-collision system is equipped with a sophisticated computer that will
record certain data, such as: • Accelerator status
•Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distance an d relative speed between your vehicle
and the vehicle ahead or other objects)
• Images from the camera sensor (available only when the pre-collision braking function or the pre-collision brake assist function was operating)
The pre-collision system does not record co nversations, sounds or images of the
inside of the vehicle.
●Data usage
Lexus may use the data recorded in this computer to diagnose malfunctions,
conduct research and develo pment, and improve quality.
Lexus will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a govern- ment agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or
vehicle owner
●Recorded images can be erased using a specialized device.
The image recording function can be disa bled. However, if the function is dis-
abled, data from when the pre-collision system operates will not be available.

WARNING
■To avoid malfunction of the camera sensor
Observe the following precautions.
Otherwise, the camera sensor may not oper ate properly, possibly leading to an acci-
dent resulting in deat h or serious injury.
●Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets, snow, etc.,
clear the windshield.
• If a glass coating agent is applied to the wi ndshield, it will still be necessary to use
the windshield wipers to remove water droplets, etc. from the area of the wind-
shield in front of the camera sensor.
• If the inner side of the windshield where th e camera sensor is installed is dirty, con-
tact your Lexus dealer.
●If the part of the windshield in front of the camera sensor is fogged up or covered with
condensation or ice, use the windshield defogger to remove the fog, condensation or
ice. ( P. 516)
●If water droplets cannot be properly removed from the area of the windshield in front
of the camera sensor by th e windshield wipers, replace the wiper insert or wiper
blade.
• To replace the wiper insert: P. 628

the vehicle inspected by your Lexus dealer.

3944-6. Driving tips
RX450h_RX450hL_U
●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 luggage 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.
