Page 55 In an accident, the child can be crushed against the windshield, or between you and the vehicle’ s interior. Lexus strongly urges the use of a proper child restraint system that conforms to the ● size of the child, installed on the rear seat. According to accident statistics, the child is safer when properly restrained in the rear seat than in the front seat.
Page 56 1-1. For safe use WARNING When children are in the vehicle ■ Do not allow children to play with the seat belt. If the seat belt becomes twisted around a child’ s neck, it may lead to choking or other serious injuries that could result in death. If this occurs and the buckle cannot be unfastened, scissors should be used to cut the belt.

Page 67 1-2. Hybrid system ◆ During normal driving The gasoline engine is predominantly used. The electric motor (traction motor) charges the hybrid battery (traction battery) as necessary. ◆ When accelerating sharply When the accelerator pedal is depressed heavily, the power of the hybrid bat- tery (traction battery) is added to that of the gasoline engine via the electric motor (traction motor).
