What You Should Know About Fail-Safe Cooling
If the engine coolant supply is depleted,this feature allows the vehicle to be driventemporarily before incremental componentdamage is incurred. The “fail-safe”distance depends on ambienttemperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the enginecoolant temperature gauge will move tothe red (hot) area and:
The coolant temperaturewarning light will illuminate.
The service engine soonindicator will illuminate.
If the engine reaches a presetover-temperature condition, the enginewill automatically switch to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs the vehicle will stilloperate. However:
•The engine power will be limited.
•The air conditioning system will bedisabled.
Continued operation will increase theengine temperature and the engine willcompletely shut down, causing steeringand braking effort to increase.
Once the engine temperature cools, theengine can be re-started. Take your vehicleto an authorized dealer as soon as possibleto minimize engine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate thevehicle in fail-safe mode only as longas necessary to bring the vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, the vehicle willhave limited power, will not be able tomaintain high-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.
Never remove the coolant reservoircap while the engine is running or hot.
You have limited engine power when in thefail-safe mode, so drive the vehicle withcaution. The vehicle will not be able tomaintain high-speed operation and theengine will run rough. Remember that theengine is capable of completely shuttingdown automatically to prevent enginedamage, therefore:
1. Pull off the road as soon as safelypossible and turn off the engine.
2. Arrange for the vehicle to be taken toan authorized dealer.
3. If this is not possible, wait a shortperiod for the engine to cool.
4. Check the coolant level and replenishif low.
5. Re-start the engine and take yourvehicle to an authorized dealer.
Note:Driving the vehicle without repairingthe engine problem increases the chance ofengine damage. Take your vehicle to anauthorized dealer as soon as possible.

Maintenance
Engine Fluid TemperatureManagement (If Equipped)
WARNINGS
To reduce the risk of collision andinjury, be prepared that the vehiclespeed may reduce and the vehiclemay not be able to accelerate with fullpower until the fluid temperatures reduce.
Never remove the coolant reservoircap while the engine is running or hot.
Your vehicle has been designed to pull atrailer, but because of the added load, thevehicle’s engine may temporarily reachhigher temperatures during severeoperating conditions such as ascending along or steep grade while pulling a trailerin hot ambient temperatures.
At this time, you may notice your enginecoolant temperature gauge needle movetoward the H and the POWER REDUCEDTO LOWER TEMP message may appearin the information display.
You may notice a reduction in the vehicle’sspeed caused by reduced engine power.In order to manage the engine fluidtemperatures, your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction will depend onthe vehicle loading, towing, grade, ambienttemperature, and other factors. If thisoccurs, there is no need to pull off the road.The vehicle can continue to be driven whilethis message is active.
The air conditioning may turn on and offduring severe operating conditions toprotect the engine from overheating. Whenthe engine coolant temperature decreasesto a more normal operating temperature,the air conditioning will turn on once again.
If the engine coolant temperature gaugemoves fully into the red (hot) area, or if thecoolant temperature warning or serviceengine soon messages appear in yourinformation display:
1. Stop your vehicle as soon as safelypossible and shift the transmission intopark (P).
2. Leave the engine running until thecoolant temperature gauge needlemoves away from the H range. Afterseveral minutes, if this does nothappen, follow the remaining steps.
3.Switch the engine off and wait for it tocool before checking the coolant level.
4. If the coolant level is normal, you mayrestart your engine and continue on.
5. If the coolant is low, add coolant,restart the engine and take your vehicleto an authorized dealer. See Addingengine coolant in this chapter for moreinformation. Refer to fail-safe coolingfor additional information.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check andchange the transmission fluid and filter atthe correct service interval. SeeScheduled Maintenance (page 453).
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.

Maintenance
•Touch-up exposed or primed metal toprevent rust.
•Cover chrome and stainless steel partswith a thick coat of auto wax to preventdiscoloration. Re-wax as necessarywhen you wash your vehicle.
•Lubricate all hood, door and luggagecompartment hinges and latches witha light grade oil.
•Cover interior trim to prevent fading.
•Keep all rubber parts free from oil andsolvents.
Engine
•Change the engine oil and filter prior tostorage because used engine oilcontains contaminates which maycause engine damage.
•Start the engine every 15 days for aminimum of 15 minutes. Run at fast idlewith the climate controls set to defrostuntil the engine reaches normaloperating temperature.
•With your foot on the brake, shiftthrough all the gears while the engineis running.
•We recommend that you change theengine oil before you use your vehicleagain.
Fuel system
•Fill the fuel tank with high-quality fueluntil the first automatic shutoff of thefuel pump nozzle.
Cooling system
•Protect against freezing temperatures.
•When removing your vehicle fromstorage, check coolant fluid level.Confirm that there are no coolingsystem leaks and that fluid is at therecommended level.
Battery
•Check and recharge as necessary. Keepconnections clean.
•If storing your vehicle for more than 30days without recharging the battery,we recommend that you disconnectthe battery cables to maintain batterycharge for quick starting.
Note:It is necessary to reset memoryfeatures if battery cables are disconnected.
Brakes
•Make sure the brakes and parking brakerelease fully.
Tires
•Maintain recommended air pressure.
Miscellaneous
•Make sure all linkages, cables, leversand pins under your vehicle are coveredwith grease to prevent rust.
•Move vehicles at least 25 ft (7.5 m)every 15 days to lubricate working partsand prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out ofstorage, do the following:
•Wash your vehicle to remove any dirtor grease film build-up on windowsurfaces.
•Check windshield wipers for anydeterioration.
•Check under the hood for any foreignmaterial that may have collectedduring storage such as mice or squirrelnests.
•Check the exhaust for any foreignmaterial that may have collectedduring storage.

Vehicle Care
•Check tire pressures and set tireinflation per the Tire Label.
•Check brake pedal operation. Driveyour vehicle 15 ft (4.5 m) back andforth to remove rust build-up.
•Check fluid levels (including coolant,oil and gas) to make sure there are noleaks, and fluids are at recommendedlevels.
•If you remove the battery, clean thebattery cable ends and check fordamage.
Contact an authorized dealer if you haveany concerns or issues.
