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.
CHANGING THE 12V BATTERY -
GASOLINE
The battery is in the engine compartment.
See Maintenance (page 380).
Your vehicle has a maintenance-free battery.
It does not require additional water during
service.
If the vehicle battery has a cover, make sure
you correctly install it after cleaning or
replacing the battery.
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.
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.
Removing the Battery
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 and isolate the negative
battery cable terminal.
5. Disconnect and isolate the positive
battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
If you disconnect or replace the vehicle
battery, you must reset the following
features:
• Window bounce-back. See Window
Bounce-Back (page 122).
• Clock Settings.
• Pre-set radio stations.
