To Keep the IMA Battery in Good Condition Drive your vehicle at least once a month, and drive for more than 30 minutes at a time. 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 IntakeIf 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 Acura hybrid
system and 12 volt battery charging system
indicators to come on.

The IMA battery cha rge level may decrease rapidly
under the following conditions:•When the 12 volt battery has been replaced.•When the IMA battery has been disconnected.•When the IMA battery control system corrects its
reading.
The charge level reading will be corrected
automatically while driving.
If the IMA battery becomes too hot or too cold, the
battery stops outputting to protect itself from
damages. This disables the hybrid system assist and
Auto Idle Stop, even though the battery is
wellcharged.
It takes a short time to normalize the IMA battery’s
output power depending on the weather.
