Auto Engine Stop/Start - Honda Acura RLX Hybrid 2016 Owner's Manual

Auto Engine Stop/Start

Your vehicle's gasoline engine will automatically stop and start during vehicle operation as needed to meet driving and battery conditions.
These are some examples that could cause the gasoline engine to automatically start.
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 state of charge is low.
When in SPORT mode, Auto Engine Stop does not activate.
Sounds Unique to the SPORT HYBRID SH-AWD® 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.
