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 IS300h, 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. A combination of both the electric motor and the gasoline engine.
