● Regenerative Energy and Regenerative Braking

operation

High Voltage Battery
● Auto Engine Stop/Start
Your vehicle's petrol 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 e:HEV
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,
and High Voltage battery cooling 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 recognise 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 petrol-powered vehicle. This function is
enhanced when the shift lever is moved to B .
