Lexus Hybrid Drive Operation

Once the READY indicator is illuminated in the instrument cluster, the vehicle may be
driven. However, the gasoline engine does not idle like a typical automobile and will
start and stop automatically. It is important to recognize and understand the READY
indicator provided in the instrument cluster. When illuminated, it informs the driver that
the vehicle is on and operational even though the gasoline engine may be off and the
engine compartment is silent.

Vehicle Operation

•
With the GS450h, the gasoline engine may stop and start at any time while the READY
indicator is on.
•
Never assume that the vehicle is shut off just because the engine is off. Always look for
the READY indicator status. The vehicle is shut off when the READY indicator is off.
The vehicle may be powered by:
1. The electric motor only.
2. The gasoline engine only.
3. A combination of both the electric motor and the gasoline engine.
