MANAGING THE COOLANTTEMPERATURE
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and thevehicle may not be able to acceleratewith full power until the coolanttemperature reduces.
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and outsidetemperature. If this occurs, there is noneed to stop your vehicle. You cancontinue to drive. See Fail-Safe Cooling(page 425).
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1.Stop your vehicle as soon as it is safeto do so. Fully apply the parking brake,shift into park (P) or neutral (N).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop afterseveral minutes, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.

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.
