Quick Reference Guide
Auto Engine Stop/Start The car will select the appropriate source of power depending on the drive mode you select.
As a result, the engine will automatically start or stop as needed to either charge the battery or provide supplemental power.
Under certain circumstances, the engine may turn on or, if it is already on, it may not turn off.
● You are going uphill or accelerating aggressively.
● The climate control system is in heavy use.
● The Ambient temperature is too hot or too cold.
● The High Voltage Battery state of charge is very low.
● The vehicle is running a system check.
System Check When the engine initially starts (between the time the POWER button is turned on and turned of f), the vehicle conducts a system check.
● While the check is being conducted, the engine may periodically turn on and off. This, however, is normal.
● The curved blue line in the POWER / CHARGE Gauge will not appear during the system check ( EV indicator may still turn on).
● Once the engine starts, it will continue to run until the system reaches operating temperature.
The curved blue line in the POWER / CHARGE Gauge will reappear once the system check is completed.

Quick Reference Guide Energy Efficiency As with a gasoline powered vehicle, the fuel efficiency and the range of this vehicle is most impacted by the driver’s driving style. Aggressive
acceleration and high-speed driving can easily trigger the system to switch the propulsion source to the gasoline-powered engin e. Climate
control system usage also has a str ong impact with heavy usage negatively affecting the vehicle’s range.
Battery Type There are two types of batteries used in this vehicle, a standa rd 12-volt battery that powers th e airbags, the interior and exterior lights, and
other standard 12-volt systems, and a high voltage battery that is used to power the propulsion motor and recharge the 12-volt battery.
Hybrid Vehicles High voltage parts and high voltag e wires in this vehicle are sheathed in electro magnetic shielding material; therefore, the am ount of
electromagnetic waves emitted is no more gr eater than those emitted by household appliances or the electrical parts in conventi onal
vehicles.
Sounds Unique to the Honda Plug-In System When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particula rly 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 conventi onal 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 unus ual noise
should one develop.
After shutting off the engi ne, 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 don’t indicate a vehicle problem.19 CLARITY PHEV-31TRW6100.book 18 ページ ２０１８年１０月２５日　木曜日　午後２時２９分
