Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When driving the vehicle ●
During normal driving, do not turn off the hybrid system. Turning the hybrid system off
while driving will not cause loss of steering or braking control, however, power assist
to the steering will be lost. This will make it more difficult to steer smoothly, so you
should pull over and stop the vehicle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the vehicle in
the normal way:  P. 5 2 9●
Use engine braking (downshift) to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause th e brakes to overheat and lose effective-
ness. (  P. 2 3 9 )●
Do not adjust the positions of the steering wh eel, the seat, or the inside or outside rear
view mirrors while driving.
Doing so may result in a loss of vehicle control. ●
Always check that all passengers’ arms, heads or other parts of their body are not
outside the vehicle. ●
AWD models: Do not drive the vehicle off-road.
This is not an AWD vehicle designed for of f-road driving. Proceed with all due cau-
tion if it becomes unavoidable to drive off-road. ●
Do not drive across a river or through other bodies of water.
This may cause electric/electronic components to short circuit, damage the hybrid
system or cause other serious damage to the vehicle. ●
Do not drive in excess of the speed limit. Ev en if the legal speed lim it permits it, do not
drive over 85 mph (140 km/h) unless your vehicle has high-speed capability tires.
Driving over 85 mph (140 km/h) may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine whether the tires on your vehicle
are high-speed capability tires or not before driving at such speeds.

RX450h_U_OM0E013U WA R N I N G
Observe the following precautions.
Failure to do so may result in death or serious injury. ■
When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift lever or
depress the accelerator pedal, this could caus e an accident or fire due to hybrid system
overheating. Additionally, if the vehicle is parked in a poorly ventilated area, exhaust
gases may collect and enter the vehicle, lead ing to death or a serious health hazard.■
When braking ●
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause one side of
the vehicle to brake differently than the other side. Also, the parking brake may not
securely hold the vehicle. ●
If the electronically controlled brake function does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is st ill possible, but the brake pedal should be depressed more
firmly than usual. Also, the braking distan ce will increase. Have your brakes fixed
immediately. ●
The brake system consists of 2 or more indi vidual hydraulic systems; if one of the sys-
tems fails, the other(s) wi ll still operate. In this case, the brake pedal should be
depressed more firmly than usual and the braking distance will increase. Have your
brakes fixed immediately. ■
If the vehicle becomes stuck (AWD models)
Do not spin the wheels excessively when any of the tires is up in the air, or the vehicle is
stuck in sand, mud, etc. This may damage th e driveline components or propel the vehi-
cle forward or backward, causing an accident.

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, hybrid transmission, rear differenti al (AWD models) or wheel bearing), Lexus
recommends that you do not tow a trailer until the vehicle has been driven for over 500
miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km), drive the vehicle at a speed of less than
50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will requir e more frequent maintenance due to the addi-
tional load. (See “Warranty and Services Guide”, “Owner’s Manual Supplement” or
“Scheduled Maintenance”.) ●
Retighten the fixing bolts of the towing ba ll and bracket after approximately 600 miles
(1000 km) of trailer towing. ■
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability.●
If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal i mmediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and trailer
should stabilize. (if enabled, Trailer Sway Cont rol can also help to stabilize the vehicle and
trailer.) ●
After the trailer sw aying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.
