12-Volt Battery
Warning
Batteries have acid that can burn you and
gas that can explode. You can be hurt
badly if you are not careful.
Always wear eye protection. Follow
instructions carefully when working
around a battery.
Battery posts, terminals and related
accessories contain lead and lead
compounds which can cause cancer and
reproductive harm. Wash hands after
handling.
Do not disconnect the 12-volt battery during
storage.
A trickle charger may be attached to the
12-volt battery terminals or trickle charge
from the underhood remote positive (+) and
negative ( ) terminals. See Jump Starting
0 329 for location of these terminals.
Caution
The vehicle is equipped with an AGM/
VRLA 12-volt battery, which can be
damaged by using the incorrect type of
trickle charger. An AGM/VRLA-compatible
charger must be used, with the
appropriate setting selected. Follow the
trickle charger manufacturer instructions.
With a trickle charger connected to the
12-volt battery, the vehicle will still monitor
the 12-volt battery daily, but it will not use
energy from the high voltage battery for
maintenance.
High Voltage Battery
After extended storage, it is possible that
the vehicle may not operate. If this happens,
the high voltage battery may need to be
plugged in and charged.
