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 -
EXCLUDING: HYBRID ELECTRIC
VEHICLE (HEV)
The battery is in the engine compartment.
See Maintenance (page 353).
Your vehicle has a maintenance-free
battery. It does not require additional
water during service.
If the vehicle battery has a cover and vent
hose, 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 What Is
Window Bounce-Back (page 119).
• Clock Settings.
• Pre-set radio stations.
Replacing the Battery
Note: Before reconnecting the battery,
make sure the ignition remains switched off.
You must replace the battery with one of
exactly the same specification.
To install, reverse the removal procedure.
Note: Make sure that you correctly install
the battery terminal covers, battery cover
and battery cable terminals.
