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 lit, 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.
•
The vehicle computer determines the mode in which the vehicle operates in
order to helps enhance fuel economy and reduce emissions. Four features
on the 2013 GS450h are EV (Electric Vehicle) mode, ECO (Economy)
mode, Sport mode, and Snow mode:
1.
EV Mode: When activated, and certain conditions have been met,
the vehicle operates with the electric motor powered by the HV
battery.
2.
ECO Mode: When activated, ECO mode helps enhance fuel
economy on trips that involve frequent braking and acceleration.
3.
Sport Mode: When activated, Sport mode optimizes acceleration
feel by increasing the power output more quickly at the beginning
of accelerator pedal operation. When Sport mode is selected, the
tachometer is displayed in the instrument cluster instead of the
Hybrid System Indicator.
4.
Snow Mode: When activated, Snow mode helps accelerator pedal
operation performance and stability when accelerating from a stop
on slippery surfaces such as a snowy road.
