■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on. If it is left off, the airbag may not deploy in the event of an accident, which may result in
serious injury or even death.

The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driv en within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the fron t bumper. Also, depending on the impact
conditions or vehicle speed , the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may oper ate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:
• Colliding with a curb
