Quick Reference Guide
The Honda IMA System
The main power source for the Honda IMA system is the gasoline engine.
The electric motor assists the engine to improve fuel economy, based on
current operating conditions.Tips to Improve Fuel Economy
To help your vehicle’s fuel economy: ● Avoid aggressive acceleration/braking
● Monitor the ambient meter and the Eco drive bar
displayed on the multi-information display.
It reflects your driving style. (P8, 86)

Quick Reference Guide
To Keep the IMA Battery in Good Condition
Drive your vehicle at least once a month for more than 30 minutes. Parking your vehicle for an extended period can cause the IMA battery
to weaken or decrease the IMA battery life. Safety Precautions
Do not cover the air intake.
Air Intake
Do not touch the Honda IMA System
A high voltage current runs through Honda IMA System. Consult your authorized dealer when
maintenance or repair is needed.
Do not spill any liquids on or around the IMA
battery, as they can damage the IMA battery. If
you accidentally spill liquids on or around the
battery, ensure that the spill is completely
wiped up as soon as possible.
The IMA system indicator may come on.

If a crash occurs ● Be careful of electric shock hazard.
uIf a crash severely damaged your vehicle, there is a possibility of electrical shock. Do not
touch the IMA system components or its wiring (orange).
● Avoid contact with IMA battery fluid.
uThe battery fluid may leak as a result of a crash. Avoid any skin or eye contact with the
fluid. The battery fluid is corro sive. If you accidentally touched it, flush your eyes or skin
with a large quantity of water for at least five minutes, and seek medical attention
immediately.
● Use a fire extinguisher for an electrical fire.
uAttempting to extinguish an electrical fire with a small quantity of water can be dangerous.
When the vehicle is disposed ● The IMA battery is a Nickel hydride battery. Honda collects and recycles used IMA batteries –
consult with your dealer for proper batter y disposal in the event your vehicle is not
repairable.
If the air intake is obstructed during
vehicle operation, the IMA battery can
become too hot. To protect the battery,
the system may start limiting IMA
battery output power and cause the IMA system and 12 volt battery
charging system indicators to come on.

Maintenance
12 Volt Battery
Checking the 12 Volt BatteryCheck the battery condition monthly. Look at
the test indicator window and check the
terminals for corrosion.
If your vehicle's battery is disconnected or goes dead: • The audio system is disabled.
2 Reactivating the audio system P. 139
• The clock resets.
2 Setting the Clock P. 98
• The navigation system *
is disabled. A PIN code will be required.
2 Refer to the navigation system manual
Charging the 12 Volt Battery
Disconnect both battery cables to prevent damaging your vehicle's electrical system.
Always disconnect the negative (-) cable first, and reconnect it last.
112 Volt Battery
WARNING: Battery post, terminals,
and related accessori es contain lead
and lead compounds. Wash your hands after handling.
The test indicator's color information is on the
battery.
When you find corrosion, clean the battery terminals
by applying a baking powder and water solution.
Rinse the terminals with water. Cloth/towel dry the
battery. Coat the terminals with grease to help
prevent future corrosion.
3WARNING
The battery gives off explosive hydrogen
gas during normal operation.
A spark or flame can cause the battery to
explode with enough force to kill or seriously hurt you.
When conducting any battery
maintenance, wear protective clothing and
a face shield, or have a skilled technician do
it.

Handling the Unexpected
If the Charging System Indicator Comes On■Reasons for the indicator to come on
Comes on when the 12 volt battery is not being charged. ■ What to do when the indicator comes on
Turn off the climate control system, rear defogger, and other electrical
systems, and immediately contact a dealer for repairs.
1If the Charging System Indicator Comes On If you need to stop temporarily, do not turn off the
engine. Restarting the engine may rapidly discharge
the 12 volt battery.
This indicator may also come on when the Auto Idle
Stop function is activated for a while. Restart the
engine. 2 Auto Idle Stop P. 228
This indicator may also come on when the IMA
battery charge drops below a desired level.
The engine starts to recharge the battery. 2 Auto Idle Stop P. 225
The indicator goes off when the battery is being
charged normally.
This indicator may blink after starting when the
outside temperature is below -20°F (-30°C). It will stop blinking after the IMA battery warms up.
