WHAT IS THE BATTERYMANAGEMENT SYSTEM
The battery management system monitorsbattery conditions and takes actions toextend battery life.
HOW DOES THE BATTERYMANAGEMENT SYSTEM WORK
If excessive battery drain is detected, thesystem temporarily disables someelectrical 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 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.
We recommend that you disconnect thenegative battery cable terminal from thebattery if you plan to store your vehicle foran extended period.
Note:If you only disconnect the negativebattery cable terminal, make sure it isisolated or placed away from the batteryterminal to avoid unintended connection orarcing.

Rear suspension components may requireregular cleaning with a power washer or athorough rinse with a strong stream ofwater if the vehicle is operated in dusty ormuddy environments. Rear leaf springs orother suspension components may emitsqueaking or popping noises whileoperating the vehicle if particles, such asdirt, rocks, or other debris, are present inthe components.
CLEANING THE EXHAUST
WARNING: Do not modify orremove the exhaust tailpipe. Blockedholes may result in increased exhaustgas temperatures, vehicle damage,property damage or personal injury.
WARNING: Failure to keep theholes in the exhaust tailpipe clean andfree of debris or foreign material mayresult in blocked holes. Blocked holesmay result in increased exhaust gastemperatures, vehicle damage, propertydamage or personal injury.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the diesel oxidationcatalytic converter or the dieselparticulate filter. The diesel oxidationcatalytic converter and the dieselparticulate filter heat up to very hightemperatures after only a short periodof engine operation and remain hot afteryou switch the engine off.
The visible holes in the exhaust tip and theholes under the shield just inboard of theright rear tire(s) are functional. Keep theholes clear of mud, debris or foreignmaterial to maintain proper function of theexhaust system. Clean and remove debrisor foreign material if present as needed.Spraying with a hose during regularwashing of vehicle should help keep holesclean and clear of debris or foreignmaterial.
CLEANING THE INTERIOR
CLEANING THE INSTRUMENTPANEL
WARNING: Do not use chemicalsolvents or strong detergents whencleaning the steering wheel orinstrument panel to avoid contaminationof the airbag system.
We recommend that you only clean theinstrument panel and cluster lens with adamp soft cloth. Dry the area with a clean,soft cloth.
