■After the 12-volt battery has discharged or when the terminal has been removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the hybrid battery
(traction battery). If this continues for a few days, contact any authorized Lexus dealer or repairer, or another duly qua lified and equipped professional.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration ev en though the vehicle is able to move with the “READY” indicator is illuminated. For sa fety, apply the parking brake and make sure to shift the shift lever to P when parked.
The following sounds or vibrations may occu r when the hybrid system is operating and are not a malfunction:
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid batter y (traction battery) under the rear seats when the hybrid system starts or stops.
●Relay operating sounds such as a snap or so ft clank will be emitted from the hybrid bat-
tery (traction battery), under the rear seat s, when the hybrid system is started or stopped.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the transmission when the gasoline engine starts or stops, when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is depressed or as the accelerator pedal is released.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent on the side of the rear seat back.
■Maintenance, repair, recycling, and disposal
Contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional regarding maintenance, repair, re cycling and disposal. Do not dispose of the
vehicle yourself.
■Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, and
turn the hybrid system off.
●Do not touch the high voltage parts, cables or connectors.
●If electric wires are exposed inside or ou tside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
●If a fluid leak occurs, do not touch the fluid as it may be strong alkaline electrolyte from the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or, if possible, boric acid solution. Seek immediate medical attention.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never use a
fire extinguisher that is not meant for electric fires. Using even a small amount of water may be dangerous.
●If your vehicle needs to be towed, do so with front wheels raised. If the wheels con-
nected to the electric motor (traction mot or) are on the ground when towing, the motor may continue to generate electricity. This may cause a fire. ( P. 530)
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto
the ground, the fuel system may have been damaged. Leave the vehicle as soon as possible.

Driving
RC300h_EE(OM24740E)
■When starting off on an uphill
The hill-start assist co ntrol will activate. (P. 304)
■For fuel-efficient driving
Keep in mind that hybrid vehicles are similar to conventional vehicles, and it is necessary
to refrain from activities such as sudden acceleration. ( P. 334)
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows may
become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially slip- pery.
●Refrain from high speeds when driving on an expressway in the rain, because there maybe a layer of water between the tires and the road surface, preventing the steering andbrakes from operating properly.
■Restraining the hybrid system output (brake override system)
●When the accelerator and brake pedals are de pressed at the same time, the hybrid sys- tem output may be restrained.
●A warning message is displayed on the multi-information display while the system is operating. ( P. 552)
■Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recommended:
●For the first 300 km (186 miles): Avoid sudden stops.
●For the first 1000 km (621 miles):
• 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.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parkin g brake system. This type of brake system needs bedding-down of the brake shoes periodically or whenever the parking brakeshoes and/or drum are replaced. Have any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional, perform the bedding down operation.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the cor-
rect fuel. ( P. 598)

2104-1. Before driving
RC300h_EE(OM24740E)
WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When the vehicle is stopped
●Do not depress the accelerator pedal unnecessarily.If the shift lever is in any position other than P or N, the vehicle may accelerate sud-denly and unexpectedly, causing an accident.
●In order to prevent accidents due to the vehicle rolling away, always keep depressingthe brake pedal while stopped with the “READY” indicator is illuminated, and applythe parking brake as necessary.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by thevehicle rolling forward or backward, alwa ys depress the brake pedal and securely apply the parking brake as needed.
●Avoid revving or racing the engine. Running the engine at high speed while the vehicle is stopped may cause the exhaustsystem to overheat, which could result in a fire if combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire. • The temperature inside the vehicle may cau se the plastic lenses and plastic mate-
rial of glasses to deform or crack. • Soft drink cans may fracture, causing the contents to spray over the interior of thevehicle, and may also cause a short circuit in the vehicle’s electrical components.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such as the glove box or on the floor, it may be lit accidentally when luggage is loaded or the
seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not place containers such as air fresheners on the instrument panel or dashboard. Adhesive discs or con-
tainers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated with a metallized film such as a silver-colored one. Reflected sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake, shift the shift lever to P, stop the hybrid system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illuminated. If the vehicle is parked with the shift lever in P but the parking brake is not set, thevehicle may start to move, possibly leading to an accident.
●Do not touch the exhaust pipes while the “READY” indicator is illuminated or imme-diately after turning the hybrid system off.Doing so may cause burns.
