NOTICE
■To prevent 12-volt battery discharge
●Do not leave the power switch in ACCESSORY or ON mode for long periods of time without the hybrid system on.
●If “ACCESSORY” or “IGNITION ON” is displayed on the meters while the hybridsystem is not operating, the power switch is not off. Exit the vehicle after turning thepower switch off.
●Do not stop the hybrid system when the shift lever is in a position other than P. If thehybrid 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 battery discharge may occur.
■When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by any autho-
rized Lexus dealer or repairer, or anothe r duly qualified and equipped professional immediately.
■Symptoms indicating a malfun ction with the power switch
If the power switch seems to be operating s omewhat differently than usual, such as the switch sticking slightly, th ere may be a malfunction. Contact any authorized Lexus dealer or repairer, or another duly qualif ied and equipped professional immediately.

■When the “-” paddle shift switch is operated with the shift lever in the D position
The shift range is downshifted to a range that enables engine braking force that is suit- able to driving conditions.
■Automatic deactivation of shift range selection in the D position
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 for more than a certain period of time
●When the shift lever is shifted to a position other than D
■Downshifting restriction warning buzzer
To help ensure safety and driving performa nce, downshifting operation may sometimes
be restricted. In some circumstances, down shifting may not be possible even when the shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the power switch is turned off after driving in snow mode.
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking, engine braking will not activate because crui se control or dynamic radar cruise control will not be canceled.
●While driving in the D or S position, downshifting to 5 or 4. ( P. 253, 257)
●When switching the driving mode to sport mode while driving in D position. (P. 301)
■Shift lock system
The shift lock system is a system to prevent accidental operation of the shift lever in start- ing.
The shift lever can be shifted from P only when the power switch is in IGNITION ON
mode and the brake pedal is being depressed.

2504-4. Refueling
RC300h_EE(OM24740E)
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do so may result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an unpainted metalsurface to discharge any static electricity. It is important to discharge static electricity before refueling because sparks resulting fr om static electricity can cause fuel vapors
to ignite while refueling.
●Always hold the grips on the fuel tank cap and turn it slowly to remove it. A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the
sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel may spray out the filler neck and cause injury.
●Do not allow anyone that has not discharged static electricity from their body to come
close to an open fuel tank.
●Do not inhale vaporized fuel. Fuel contains substances that are harmful if inhaled.
●Do not smoke while refueling the vehicle.Doing so may cause the fuel to ignite and cause a fire.
●Do not return to the vehicle or touch any person or object that is statically charged.
This may cause static electricity to build up, resulting in a possible ignition hazard.
■When refueling
Observe the following precautions to prevent fuel overflowing from the fuel tank:
●Securely insert the fuel nozzle into the fuel filler neck.
●Stop filling the tank after the fuel nozzle automatically clicks off.
●Do not top off the fuel tank.
NOTICE
■Refueling
Do not spill fuel during refueling. Doing so may damage the vehicle, such as causing the emission control system tooperate abnormally or damaging fuel system components or the vehicle’s painted sur-
face.

4707-3. Do-it-yourself maintenance
RC300h_EE(OM24740E)
WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energize d. To avoid death or serious injury, observe the following precautions.
■When working on the engine compartment
●Make sure that the “ACCESSORY” or “IGNITION ON” on the multi-informationdisplay and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after drivingas they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the enginecompartment.
●Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes are flamma-
ble.
●Be extremely cautious when working on the 12-volt battery. It contains poisonous and corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted sur- faces. If fluid gets on your hands or in your eyes, flush the affected area with cleanwater immediately.
If you still experience discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automatically start to run if the air conditioning is on and/or the coolant temperature is high. ( P. 480)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt
in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high. If the reservoir needs frequent refillin g, it may indicate a serious problem.
