Hybrid Synergy Drive Operation - Toyota Highlander 2008 Emergency Response Manual

Hybrid Synergy 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 Highlander hybrid, 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 motors only.
2. The gasoline engine only.
3. A combination of both the electric motors and the gasoline engine.

The vehicle computer determines the mode in which the vehicle operates in
order to improve fuel economy and reduce emissions. Two new features on
the 2008 Highlander hybrid are EV (Electric Vehicle) drive mode and
ECON (Economy) drive mode:
1.
EV Drive Mode: When activated, and certain conditions have
been met, the vehicle operates with the electric motor powered by
the HV battery.
2. Economy Drive Mode: When activated, this mode helps enhance
fuel economy on trips that involve frequent braking and
acceleration.
