AGM battery setting on the charger.
If available, use the AGM setting on the
charger, to limit charge voltage to 14.8 volts.

Warning
Batteries have acid that can burn you and
gas that can explode. You can be badly
hurt if you are not careful. Always wear
eye protection. See Jump Starting - North
America 0 122 for tips on working around
a battery without getting hurt.
Vehicle Care
The best way to store the vehicle for any
length of time is to plug in the charge cord
and leave it plugged in. The vehicle
monitors and maintains the 12-volt battery
daily. It is OK to leave the vehicle plugged
in for extended periods of time. Once
charged to full, very little energy is required
to maintain the 12-volt battery and high
voltage battery.
If it is not possible to charge the vehicle
with the charge cord left plugged in, be sure
to fully charge the high voltage battery
before storing. The vehicle will stop
maintenance of the 12-volt battery if the
high voltage battery state of charge gets
too low.
When storing the vehicle on a long-term
basis:
‐ Keep the high voltage battery state of
charge at 30%.
‐ Attach an AGM/VRLA compatible battery
tender or trickle charger to the 12-volt
battery.
‐ Keep the remote key more than 3 m
(10 ft) away from the vehicle.
A trickle charger may be attached to the
12-volt battery terminals or trickle charge
from the underhood remote positive (+) and
