Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 194).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, thecoolant temperature gauge moves towardthe red zone:
A warning lamp illuminates anda message may appear in theinformation display.
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. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as longas necessary to bring your vehicle to restin a safe location and seek immediaterepairs. When in fail-safe mode, yourvehicle will have limited power, will not beable to maintain high-speed operation, andmay completely shut down withoutwarning, potentially losing engine power,power steering assist, and power brakeassist, which may increase the possibilityof a crash resulting in serious injury.
Never remove the coolant reservoircap when the engine is running orhot.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1. Pull off the road as soon as safelypossible and switch the engine off.
2. If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3. If this is not possible, wait a shortperiod for the engine to cool.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5. When the engine temperature cools,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine damage.

Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING
To reduce the risk of crash and injury,be prepared that the vehicle speedmay reduce and the vehicle may notbe able to accelerate with full power untilthe coolant temperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep slope in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
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 ambienttemperature. If this occurs, there is no needto pull off the road. You can continue todrive your vehicle.
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. Pull off the road as soon as safelypossible and shift the transmission intopark (P).
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, immediately addprediluted coolant.
5. If the coolant level is normal, restartthe engine and continue driving.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check andchange the transmission fluid and filter atthe correct service interval. SeeScheduled Maintenance (page 270).
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.

Checking Automatic TransmissionFluid
For scheduled intervals of the fluid checksand changes, See ScheduledMaintenance (page 270). Yourtransmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,i.e., if the transmission slips or shifts slowlyor if you notice some sign of fluid leakage.
Automatic transmission fluid expandswhen warmed. To obtain an accurate fluidcheck, drive the vehicle until it is at normaloperating temperature (approximately19 mi (30 km)). Verify that thetransmission fluid temperature gauge,located on the instrument cluster, is withinnormal range.
1. Drive the vehicle 19 mi (30 km) until itreaches normal operating temperature.
2.Park the vehicle on a level surface andengage the parking brake.
3.With the engine running, parking brakeengaged and your foot on the brakepedal, move the gearshift lever throughall of the gear ranges. Allow sufficienttime for each gear to engage.
4. Put the transmission in park (P) andleave the engine running.
5. Remove the dipstick, wiping it cleanwith a clean, dry lint free rag. Ifnecessary, refer to the Under HoodOverview in this chapter for thelocation of the dipstick.
6.Install the dipstick making sure it is fullyseated in the filler tube.
7. Remove the dipstick and inspect thefluid level. The fluid should be in thedesignated area for normal operatingtemperature or ambient temperature.
Low Fluid Level
