RC300h_EE(OM24740E)
■Sounds and vibrations caused by the ABS, brake assist, TRC, VSC and hill-start assist control systems
Any of the following conditions may occur when the above systems are operating. None
of these indicates that a malfunction has occurred.
●Vibrations may be felt through the vehicle body and steering.
●A motor sound may be heard after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the follow ing cases, but it does not indicate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake pedal is oper-ated.
●Motor sound of the brake system heard from the front part of the vehicle when the
driver’s door is opened.
●Operating sound heard from the engine compartment when one or two minutes passed after the stop of the hybrid system.
■EPS operation sound
When the steering wheel is operated, a motor sound may be heard. This does not indi- cate a malfunction.
■Reactivation of the TRC/VSC systems
Even after the TRC/VSC systems have been turned off, turning the hybrid system off and then on again will automatically reactivate the TRC/VSC systems.
■Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, th e TRC system will turn on when vehicle speed increases. However, when both TRC and VSC systems are turned off, the systems will
not turn on even when vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is redu ced to prevent the system from overheating when there is frequent steering input over an extended period of time. The steeringwheel may feel heavy as a result. Should this occur, refrain from excessive steering input
or stop the vehicle and turn the hybrid system off. The EPS system should return to nor- mal within 10 minutes.
■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will operate:
●The shift lever is in a position other than P or N (when starting off forward/backward on an upward incline).
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●The shift lever is moved to P or N.
●The accelerator pedal is depressed.
●The parking brake is engaged.
●Approximately 2 seconds elapse after the brake pedal is released.

RC300h_EE(OM24740E)
■While towing
If the hybrid system is off, the power assist for the brakes and steering will not function, making steering and braking more difficult.
■Wheel nut wrench
Wheel nut wrench is installed in trunk. ( P. 565)
WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When towing the vehicle
■While towing
●When towing using cables or chains, avoid sudden starts, etc. which place excessivestress on the towing eyelets, cables or ch ains. The towing eyelets, cables or chains may become damaged, broken debris ma y hit people, and cause serious damage.
●Do not turn the power switch off. There is a possibility that the steering wheel is locked and cannot be operated.
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely. If not securely installed, towing ey elets may come loose during towing.
Be sure to transport the vehicle with all four wheels raised off the ground. If the vehicle is
towed with the tires contacting the ground, the drivetrain and related parts may be damaged,an accident may occur due to a change in
direction of the vehicle or electricity generated by the operation of the motor may cause a fireto occur depending on the nature of the dam-
age or malfunction.
