WARNING: The recovery hook canbecome hot. Let the recovery hook cooldown before removing it. Failure to doso could result in personal injury.
Your vehicle has frame-mounted frontrecovery hooks.
Note:Do not apply a load to the recoveryhooks that is greater than the gross vehicleweight rating of your vehicle.
Before using recovery hooks:
•Make sure all attaching points aresecure and capable of withstandingthe applied load.
•Do not use chains, cables or tow strapswith metal hook ends.
•Only use recovery straps that have aminimum breaking strength two tothree times the gross vehicle weight ofthe stuck vehicle.
•Make sure the recovery strap is in goodcondition and free of visible cuts, tearsor damage.
•Use a damper device such as a tarp,heavy blanket or piece of carpet, andplace it over the recovery strap to helpabsorb the energy in the event thestrap breaks.
•Make sure the stuck vehicle is notloaded heavier than its gross vehicleweight rating specified on thecertification label.
•Align the tow vehicle and stuck vehiclein a straight line, within 10 degrees.
•Keep bystanders to the sides of thevehicle, at a distance of at least twicethe length of the recovery strap. Thishelps avoid injury from the hazard of arecovery hook or strap breaking, or avehicle lurching into their path.

We recommend the use of a wheel lift anddollies or flatbed equipment to tow yourvehicle. Vehicle damage could occur iftowed incorrectly, or by any other means.
Front-wheel and rear-wheel drive vehiclesmust have their designated drive wheelsoff the ground regardless of towingdirection. Use tow dollies to preventdamage to the transmission.
All-wheel or four-wheel drive vehiclesrequire that all wheels be off the groundusing a wheel lift and dollies or flatbedequipment. This prevents damage to thetransmission and drive system.
Note:You need to switch on the ignition tounlock the steering.
Note:Make sure you check the steeringcolumn before towing. It could lock if thebattery is dead.
FAIL-SAFE COOLING
WHAT IS FAIL-SAFE COOLING
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs due tooverheating.
The fail-safe distance depends on outsidetemperature, vehicle load and terrain.
HOW DOES FAIL-SAFE COOLINGWORK
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine.
Note:Have your vehicle checked as soonas possible to minimize engine damage.
DRIVING WHEN FAIL-SAFE MODEIS ACTIVATED
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.

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.
