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 the 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 conventional
vehicles.
Sounds Unique to the Honda Plug-In 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 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.

Shows the remaining high voltage battery charge level.
■High Voltage Battery Charge Level Gauge1High Voltage Battery Charge Level Gauge
When the number of bars displayed on the High
Voltage Battery Charge Level Gauge becomes one,
assist by the high-voltage battery is limited and the
vehicle output is lowered.
The high voltage battery ch arge level may decrease
under the following conditions:
•When the 12-volt battery has been replaced.•When the 12-volt battery has been disconnected.
•When the high voltage battery control system
corrects its reading.
The charge level reading will be corrected
automatically while driving.
Changes in the temperature of the high voltage
battery can increase or decrease the battery’s
charging capacity. If temp erature changes cause the
battery’s capacity to change, the number of
indicators in the battery ch arge level gauge may also
change, even if the amount of charge remains the
same.
