■Breaking in your new Lexus
To extend the life of the vehicle, observin g the following precautions is recommended:
●For the first 200 miles (300 km):
Avoid sudden stops.
●For the first 500 miles (800 km):
Do not tow a trailer.
●For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. ( P. 591)
■Eco-friendly driving
 P. 121
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY” indicator is
illuminated. This prevents the vehicle from creeping.
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator ped-
als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will
result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to difficulty in operat-
ing the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving po sture even when moving the vehicle only
slightly. This allows you to depress the brake and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, resulting in an accident.
●The driver should pay extra attention to pedestrians when the vehicle is powered only
by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s movement.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may
cause a fire if there is any flammable material nearby.

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.

Driving
RX450h_U_OM0E013U
●To maintain engine braking efficiency and charging system performance
when using engine braking, do no t put the transmission in D. (P. 239)
●Instability happens more fr equently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending st eep or long downhill grades.
●Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency.
●Due to the added load of the trailer, yo ur vehicle’s engine may overheat on hot
days (at temperatures over 85 F [30 C]) when driving up a long or steep
grade. If the engine coolant temperat ure gauge indicates overheating, imme-
diately turn off the air conditioning (if in use), pull your vehicle off the road and
stop in a safe spot. ( P. 574)
●Always place wheel blocks under both the vehicle’s and the trailer’s wheels
when parking. Put the transmission in P and apply the parking brake. Avoid
parking on a slope, but if unavoidable, do so only after performing the follow-
ing:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and trailer’s
wheels.
When the wheel blocks are in place, release the brakes slowly until the
blocks absorb the load.
Shift into P and apply the parking brake.
Turn off the hybrid system.
●When restarting afte r parking on a slope:
With the transmission in P, start the hybrid system. Be sure to keep the
brake pedal depressed.
Shift into a forward gear. If reversing, shift into R.
If the parking brake is in manual mode, release the parking brake.
( P. 246)
Release the brake pedal, and slowly pull or back away from the wheel
blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

■Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, hybrid transmission, rear differential (AWD models) or wheel bearing), Lexus
recommends that you do not tow a trailer unt il 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 require 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 ve hicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal im mediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the st eering or brakes, your vehicle and trailer
should stabilize. (if enabled, Trailer Sway Control can also he lp 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 ov erloaded 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.

WARNING
■When starting the hybrid system
Always start the hybrid system while sittin g in the driver’s seat. Do not depress the
accelerator pedal while starting the hybrid system under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Caution while driving
If hybrid system failure occurs while the ve hicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the steering lock
in this circumstance may lead to an accident, resulting in death or serious injury.
■Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehicle, press
and hold the power switch for more than 2 se conds, or press it briefly 3 times or more
in succession. ( P. 529)
However, do not touch the power switch while driving except in an emergency. 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.
NOTICE
■To prevent 12-volt battery discharge
●Do not leave the power swit ch in ACCESSORY or ON mode for long periods of
time without the hybrid system on.
●If “ACCESSORY” or “IGNITION ON” is di splayed on the meters while the hybrid
system is not operating, the power switch is not off. Exit the vehicle after turning the
power switch off.
●Do not stop the hybrid system when the shift lever is in a position other than P. If the
hybrid system is stopped in another shift lever position , the power switch will not be
turned off but instead be turned to ACCESSORY mode. If the vehicle is left in
ACCESSORY mode, 12-volt ba ttery discharge may occur.
■When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by your Lexus
dealer immediately.
■Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating somewhat differen tly than usual, such as the
switch sticking slightly, there may be a malfunction. Contact your Lexus dealer immedi-
ately.

■When the “-” paddle shift switch is operated with the shift lever in the D position (vehi-
cles with paddle shift switches)
The shift range is downshifted to a range that enables engine braking force that is suit-
able to driving conditions.
■Automatic deactivation of shif t range selection in the D position (vehicles with paddle
shift switches)
Shift range selection in the D position will be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pedal is depressed fo r more than a certain period of time
●When the shift lever is shifted to a position other than D
■S mode
●When the shift range is S4 or lower, holding the shift lever toward “+” sets the shift
range to S6.
●Automatically selects a higher shift range before the engine speed becomes too high.
■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshifti ng operation may sometimes
be restricted. In some circum stances, downshifting may not be possible even when the
shift lever or paddle shift sw itch (if equipped) is operated . (A buzzer will sound twice.)
■When driving with cruise control, dynamic radar cruise control or dynamic radar
cruise control with full-speed range activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because crui se control, dynamic radar cruise control or
dynamic radar cruise control with full-speed range will not be canceled.
●Vehicles without paddle shift switches: While driving in S mode, downshifting to 5 or 4.
(  P. 311, 323, 335)
●Vehicles with paddle shift sw itches: While driving in D or S mode, downshifting to 5 or
4. ( P. 311, 323, 335)
●When switching the driving mode to sport mode while driving in D position.
( P. 377)
■Restraining sudden start (Drive-Start Control)
When the following unusual operation is performed, the hybrid system output may be
restrained.
●When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to R (D includes S)
with the accelerator pedal depressed, a wa rning message appears on the multi-infor-
mation display. If a warning message is shown on the multi- information display, read the
message and follow the instructions.
