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.

Changing the 12V Battery

The battery is in the engine compartment.

Your vehicle has a maintenance-free battery. It does not require additional water during service.

Note: There may be additional components that need to be removed or disconnected before you can safely remove the battery from your vehicle. For specific guidance on which components may need to be addressed, it is best to contact your dealer for detailed information.

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 allows the system to store diagnostic and adaptive tables. Disconnecting the battery without waiting can cause damage not covered by the vehicle Warranty.

  1. Disconnect and isolate the negative battery cable terminal.
  2. Disconnect and isolate the positive battery cable terminal.

Note: Before removing batteries with a vent tube, disconnect and secure the tube.

  1. Remove the battery securing clamp.
  2. Remove the battery.

If you disconnect or replace the vehicle battery, you must reset the following features:

  • Window bounce-back.
  • 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 cable terminals, battery terminal covers, battery vent tube, battery securing clamp and battery cover.
