•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message could appear in the informationdisplay to alert you that battery protectionactions are active. This message is only fornotification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
BATTERY MANAGEMENT SYSTEMLIMITATIONS
After battery replacement, or in somecases after charging the battery with anexternal charger, the battery managementsystem requires eight hours of vehicle sleeptime to relearn the battery state of charge.During this time, your vehicle must remainfully locked with the ignition switched off.
Note:Prior to relearning the battery stateof charge, the battery management systemcould temporarily disable some electricalsystems.
Electrical Accessory Installation
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the battery negative post. Thiscan cause inaccurate measurements ofthe battery condition and potentialincorrect system operation.
Note:If you add electrical accessories orcomponents to the vehicle, it couldadversely affect battery performance anddurability. This could also affect theperformance of other electrical systems inthe vehicle.
CHANGING THE 12V BATTERY
The battery is in the engine compartment.See Maintenance (page 440).
Your vehicle has a maintenance-freebattery. It does not require additionalwater during service.
If the vehicle battery has a cover, makesure you correctly install it after cleaningor replacing the battery.
For longer, trouble-free operation, keep thetop of the battery clean and dry and thebattery cables tightly fastened to thebattery terminals. If any corrosion ispresent on the battery or terminals, removethe cables from the terminals and cleanwith a wire brush. You can neutralize theacid with a solution of baking soda andwater.
