CHARGING THE 12V BATTERY
Battery Management System (If
Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system may
temporarily disable certain electrical
features to protect the battery. Those
electrical accessories affected include the
rear defrost, heated/cooled seats, climate
control fan, heated steering wheel, audio
and navigation system. A message may be
shown in the information displays to alert
the driver that battery protection actions
are active. These messages are only for
notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
Electrical accessory installation
Note: Charging and replacing the battery
requires the driver power window to be
re-initialized. See Windows and Mirrors
(page 82).
To ensure proper operation of the Battery
Management System, any electrical
devices that are added to your vehicle
should not have their ground connection
made directly at the negative battery post.
A connection at the negative battery
terminal can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
When a battery replacement is required,
you must use a recommended
replacement battery that matches the
electrical requirements of the vehicle.
After battery replacement, or in some
cases after charging the battery with the
external charger, the Battery Management
System requires eight hours of vehicle
sleep time (key off with doors closed) to
relearn the new battery state of charge.
Prior to relearning the state of charge, the
Battery Management System may disable
electrical features (to protect the battery)
earlier than normal.
CHANGING THE 12V BATTERY
WARNING: Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide correct ventilation.
WARNING: When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in
personal injury and damage to the
vehicle or battery. Lift the battery with a
battery carrier or with your hands on
opposite corners.
WARNING: Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately.
