● Auto Engine Stop/Start
Your vehicle's gasoline engine automatically stops running during vehicle operation or restarts while the vehicle is stationary when it is
appropriate.
In the following cases, however, auto engine stop may not activate.
•
The vehicle momentarily needs additional power for aggressive acceleration, or driving uphill or at high speed.
•
The climate control system is in heavy use.
•
The High Voltage battery temperature is high or low.
● Sounds Unique to the SPORT HYBRID i-MMD System
When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particularly when you first turn on the power system,
while driving, and just after parking. 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.
When decelerating without the accelerator being depressed or the brake pedal being applied, or
while driving downhill, the electric motor acts as a generator that recovers a portion of the
electrical energy that was used to accelerate the vehicle. This regenerative braking slows the
vehicle in a manner similar to engine braking in a gasoline-powered vehicle. This function is
enhanced when the shift lever is moved to B .
