For safety and security

■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the extremely high speed deployment (inflation) by hot gases.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as theseats, the glove box, parts of the front and re ar pillars, and roof side rails may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●Vehicles with ERA-GLONASS: If the SRS ai rbags deploy, the system is designed to send an emergency call* to the Public Safety Answer ing Point (PSAP), notifying them
of the vehicle’s location (without needing to push the “SOS” button) and an agent will attempt to speak with the occupants to ascertain the level of emergency and assistancerequired. If the occupants are unable to communicate, the agent automatically treats
the call as an emergency and helps to di spatch the necessary emergency services. ( P. 384)
*: In some cases, the call cannot be made. (P. 386)
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set thresh- old level (the level of force corresponding to an approximately 20 - 30 km/h [12 - 18mph] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be cons iderably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possib le that only the seat belt pretensioners will activate.
■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags w ill deploy in the event of an impact that exceeds the set threshold level (the level of force corresponding to the impact forceproduced by an approximately 1500 kg [3300 lb.] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
●The SRS side and curtain shield airbags may also deploy in the event of a severe frontal
collision.

■Sounds and vibrations caused by the ABS, brake assist, VSC, Hill-start assist control, TRC and VGRS 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 operation 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 sounds 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, VGRS and DRS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard. This does not indicate a malfunction.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically re-enabled in the following situations:
●When the power switch is turned off
●If only the TRC system is turned off, the TR C will turn on when vehicle speed increases If both TRC and VSC systems are turned off, automatic re-enabling will not occur when
vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced 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 N or P (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.
