■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)

2084-1. Before driving
RC300h_EE(OM24740E)
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 a difficulty in oper- ating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture 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.
●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. 529
●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. 222)
●Do not adjust the positions of the steering wheel, 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 notoutside the vehicle.

WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that the brakes are functioning properly. Wet brak e pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not functioning properly, steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward while the shift lever is in a driving position, or roll forward while the shift lever is in R.Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving. Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to a driving position while the vehicle is moving backward. Doing so can damage the transmission and may result in a loss of vehicle control.
●Shifting the shift lever to N while the vehicle is moving will disengage the hybrid sys- tem. Engine braking is not available when N is selected.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to any position other than P or N may lead to unexpected rapid accelera- tion of the vehicle that may cause an accident and result in death or serious injury.
■If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus dealer or repairer, or another duly qualified and equi pped professional as soon as possible. Rotor damage may result if the pads are not replaced when needed.
Moderate levels of the brake pad and disc wear allow enhanced braking power. As a result, the discs may wear more quickly than conventional brake discs. Therefore, when replacing the brake pads, Lexus recommends that you also have the thickness of the
discs measured. It is dangerous to drive the vehicle when th e wear limits of the brake pads and/or those of the brake discs are exceeded.

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.

WARNING
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. Otherwis e, if you accidentally move the shift lever or depress the accelerator pedal, this could cause an accident or fire due to hybrid systemoverheating. 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 notsecurely hold the vehicle.
●If the electronically controlled brake system does not operate, do not follow othervehicles closely and avoid hills or sharp turns that require braking.In this case, braking is still possible, bu t the brake pedal should be depressed more
firmly than usual. Also, the braking distance will increase. Have your brakes fixed immediately.
●The brake system consists of 2 or more individual hydraulic systems; if one of the sys-
tems fails, the other(s) will 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
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.

RC300h_EE(OM24740E)
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time while driving, as this may restrain the hybrid system output.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at thesame time to hold the vehicle on a hill.
■When parking the vehicle
Always set the parking brake, and shift the sh ift lever to P. Failure to do so may cause the vehicle to move or the vehicle may accelerate suddenly if the accelerator pedal isaccidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for anextended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, driv e as slowly as possible to avoid damaging the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 563)
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, hybrid transmis-
sion, differentials, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where possible), and the function of all joints, bearings, etc.
