SPORT HYBRID i-MMD SYSTEM MAIN COMPONENTS
Gasoline Engine – Runs the generator and under certain
conditions, drives the wheels directly.
Generator – Starts the engine and generates electric power
when driven by the gasoline engine to supply electricity to
power the electric motor and/or to charge the High Voltage
battery.
– Provides propulsion to drive the wheels in
Electric Motor
conjunction with the gasoline engine in certain conditions and
provides electricity to the High Voltage battery through
regenerative braking.
– Provides electrical storage and serves
High Voltage Battery
as a power source for the electric motor.
Learning about the High Voltage battery's characteristics will
help you get the best handling and maximize the range of your
electric vehicle. (P402)
● Sounds Unique to the SPORT HYBRID i-MMD System
When you first start driving this vehicle, you will likely hear some unfamiliar sounds, particularly when you turn on the power system, or
while you are driving or accelerating from a stop. Some of these sounds are unique to this vehicle's powertrain, fuel, and climate control
systems; others are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a
vehicle of this design. These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any
new or unusual noise should one develop.
After shutting off the engine, you may hear certain noises coming from the vehicle. Here's the lowdown:
● Noise from Under Vehicle: This noise is caused by the vacuum pump inside the fuel evaporation leakage check module (ELCM).
Depending on conditions, the pump will come on for about 15 minutes about 5 to 10 hours after engine shutoff. This noise is just normal
vehicle operation and doesn't indicate a vehicle problem.
