Quick Reference Guide
●Regenerative Energy and Regenerative BrakingWhen 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. You can control the
rate of deceleration by using the deceleration paddle selector.
●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.
•The High Voltage battery is too low on charge.
●Sounds Unique to the SPORT HYBRID i-MMD System
When you first start driving this vehicle, you will likely hear so me unfamiliar sounds, particularly when you turn on the power system, or
while you are driving or accelerating from a stop. Some of thes e 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 f rom 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 ma y 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.
