RC300h_EE(OM24740E)
■Pop Up Hood precautions
●Before scrapping your vehicle, make sure to contact any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
●The Pop Up Hood system cannot be reused once it has operated. Have it replaced by
any authorized Lexus dealer or repairer, or another duly qualified and equipped profes- sional.
■Conditions under which the Pop Up Hood may not operate properly
The Pop Up Hood may not operate prop erly under the following conditions:
●If a pedestrian collides with the right or left corner of the front bumper or the side of the vehicle. As such impacts may be difficul t to detect, the system may not operate.
●If the vehicle speed is not detected correctly, such as if the vehicle is sliding sideways, the system may not operate properly.
■Conditions under wh ich the Pop Up Hood may not operate
The Pop Up Hood may not operate in the following situations:
●Colliding with a lying pedestrian
●A frontal impact applied to the front bumper while driving at speeds outside of the
operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident situations, the Pop Up Hood may operate.)
NOTICE
■Pop Up Hood precautions
●Make sure to close the hood before driving, as the system may not operate properly if the hood is not fully closed.
●Make sure that all 4 tires are of the specif ied size and inflated to the specified tire
pressure ( P. 604). If tires of a different size are used, the system may not operate properly.
●If something has hit the area around the front bumper, the sensors may be damaged
even if the Pop Up Hood has not operated. Have the vehicle inspected by any autho- rized Lexus dealer or repairer, or anothe r duly qualified and equipped professional.
●Do not remove or repair the parts or wiring of the Pop Up Hood, as doing so may
cause accidental operation or prevent the sy stem from operating properly. If repair or replacement is necessary, contact any authorized Lexus dealer or repairer, oranother duly qualified an d equipped professional.
●Do not remove such components as the front bumper, hood or suspension, or replace them with non-genuine parts, as doing so may prevent the system from oper-ating properly.
●Do not install anything to the front bumper or hood, as doing so may prevent the sen-sors from detecting an impact correctly and prevent the system from operating prop-erly.
●Do not close the hood with force or apply load to the lifters, as doing so may damage the lifters and prevent the system from operating properly.
●Do not modify the suspension, as changes made to the vehicle height may prevent
the system from operating properly.

For safety and security
RC300h_EE(OM24740E)
■Tilt sensor detection considerations
The sensor may trigger the alarm in the following situations:
●The vehicle is transported by a ferry, trailer, train, etc.
●The vehicle is parked in a parking garage.
●The vehicle is inside a car wash that moves the vehicle.
●Any of the tires loses air pressure.
●The vehicle is jacked up.
●An earthquake occurs or the road caves in.
NOTICE
■To ensure the intrusion sensor function correctly
●Installing accessories other than genuine Lexus parts or leaving objects between the driver’s seat and front passenger’s seat may reduce the detection performance.
●To ensure that the sensors operate properly,do not touch or cover them.
●Do not spray air freshe ners or other products directly into the sensor holes.

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)

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.

The indicator comes on when the ASC system is on.
When the dial is turned to the lowest volume, the ASC system will be turnedoff and the indicator will go off.
■The ASC system can be operated when
The driving mode select switch is in normal mode or sport mode. (P. 301)
■Temporary cancelation of the ASC system functions
The ASC system may be temporarily cancel ed depending on the driving conditions, such as when the tires slip due to sudden acceleration.
ASC (Active Sound Control)
: If equipped
The ASC system is an electronic soun d system that generates engine sound,
conveying the kinetic situations of the vehicle’s acceleration and deceleration
to the driver through the speakers inside the instrument panel.
The vehicle’s response to the driver’s acceleration behavior and shift opera-
tions are also conveyed in sound.
When sport mode is selected, the sound conveyed to the driver will be louder.

●When sunlight or the headlights of oncoming vehicles are shining directly into the cam- era lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet du e to rain, previous rainfall, standing water, etc.
●When the vehicle experiences strong up-and-down motion such as when driving on an
extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or when the headlights are misaligned
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■Warning messages for the LDA system
Warning messages are used to indicate a syst em malfunction or to inform the driver of
the need for caution while driving. ( P. 549)
WARNING
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the vehicle auto- matically, nor does it reduce the amount of care you need to take. As such, the driver
must always assume full responsibility fo r understanding his/her surroundings, for operating the steering wheel to correct the driving line, and for driving safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
■Situations unsuitable for LDA system
Do not use the LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with tire chains, a spare tire, or similar equipment
●When there are objects or structures along the roadside that might be misinterpreted as lane markers (such as guardrails, a curb, reflector posts, etc.)
●When driving on snowy roads
●When pavement lane markers are difficult to see due to rain, snow, fog, sand, dirt, etc.
●When there are visible lines on the pavement from road repairs, or if the remains of old lane markers are still visible on the road
●When driving on a road with lane closures due to maintenance, or when driving in a temporary lane
