12V BATTERY
12V BATTERY PRECAUTIONS
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.
WARNING: Battery posts,
terminals and related accessories
contain lead and lead compounds,
chemicals known to the State of
California to cause cancer and
reproductive harm. Wash your hands
after handling.
WARNING: This vehicle may have
more than one battery. Removing the
battery cables from only one battery
does not disconnect your vehicle
electrical system. Make sure you
disconnect the battery cables from all
batteries when disconnecting power.
Failure to do so may cause serious
personal injury or property damage.
WARNING: For vehicles with
Auto-Start-Stop the battery requirement
is different. You must replace the battery
with one of exactly the same
specification.

Maintenance

WHAT IS THE BATTERY
MANAGEMENT SYSTEM
The battery management system monitors
battery conditions and takes actions to
extend battery life.
HOW DOES THE BATTERY
MANAGEMENT SYSTEM WORK
If excessive battery drain is detected, the
system temporarily disables some
electrical systems to protect the battery.
Systems included are:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message could appear in the information
display to alert you that battery protection
actions are active. This message is only for
notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
BATTERY MANAGEMENT SYSTEM
LIMITATIONS
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time, your vehicle must remain
fully locked with the ignition switched off.
Note:Prior to relearning the battery state
of charge, the battery management system
could temporarily disable some electrical
systems.
Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the battery negative post. This
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to the vehicle, it could
adversely affect battery performance and
durability. This could also affect the
performance of other electrical systems in
the vehicle.
RESETTING THE BATTERY
SENSOR
When you install a new battery, reset the
battery sensor by doing the following:
1. Switch the ignition on, and leave the engine off.
Note: Complete Steps 2 and 3 within 10
seconds.
2. Flash the high beam headlamps five times, ending with the high beams off.
3. Press and release the brake pedal three times.
The battery warning lamp flashes three
times to confirm that the reset is
successful.
RECYCLING AND DISPOSING OF
THE 12V BATTERY
E107998
Make sure that you dispose of
old batteries in an
environmentally friendly way.
Seek advice from your local authority
about recycling old batteries.

Maintenance

CHANGING THE 12V BATTERY
The battery is in the engine compartment.
See Under Hood Overview (page 330).
Your vehicle has a maintenance-free
battery. It does not require additional
water during service.
For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the
battery terminals. If any corrosion is
present on the battery or terminals, remove
the cables from the terminals and clean
with a wire brush. You can neutralize the
acid with a solution of baking soda and
water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note: If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
To maintain correct operation of the
battery management system, if you add
any electrical devices to your vehicle, do
not connect the ground connection directly
to the negative battery terminal. A
connection at the negative battery terminal
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to your vehicle this may
adversely affect battery performance,
durability and the performance of other
electrical systems on your vehicle.
If you replace the battery make sure it
matches the electrical requirements of
your vehicle. If you disconnect or replace the battery
and your vehicle has an automatic
transmission, it must relearn its adaptive
strategy. Because of this, the transmission
may shift firmly when first driven. This is
normal operation while the transmission
fully updates its operation to optimum
shift feel.
Remove and Reinstall the Battery
To disconnect or remove the battery, do
the following:
1. Apply the parking brake and switch the
ignition off.
2. Switch all electrical equipment off, for example lights and radio.
3. Wait a minimum of two minutes before disconnecting the battery.
Note: The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty.
4. Disconnect the negative battery cable terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal procedure.
Note: Before reconnecting the battery,
make sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened.
Note: After cleaning or replacing the
battery, make sure you reinstall the battery
cover or shield.
