Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Coolant Change
Change the engine coolant at the specificmileage intervals listed in scheduledmaintenance. See Capacities andSpecifications (page 226).
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 theinstrument cluster display.
If the engine reaches a presetover-temperature condition, itautomatically 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 restart the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is 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.

Tire Rotation
WARNING: If the tire labelshows different tire pressures forthe front and rear tires and thevehicle has a tire pressuremonitoring system, then youneed to update the settings forthe system sensors. Alwaysperform the system resetprocedure after tire rotation. Ifyou do not reset the system, itmay not provide a low tirepressure warning whennecessary.
Note:If your tires show unevenwear ask an authorized dealer tocheck for and correct any wheelmisalignment, tire imbalance ormechanical problem involvedbefore tire rotation.
Note:Your vehicle may beequipped with a dissimilar sparewheel and tire assembly. Adissimilar spare wheel and tireassembly is defined as a sparewheel and tire assembly that isdifferent in brand, size orappearance from the road tires andwheels. If you have a dissimilarspare wheel and tire assembly it isintended for temporary use onlyand should not be used in a tirerotation.
Note:After having your tiresrotated, inflation pressure must bechecked and adjusted to the
vehicle requirements.
Rotating your tires at therecommended interval (asindicated in the ScheduledMaintenance chapter) helps yourtires wear more evenly, providingbetter tire performance and longertire life. Sometime irregular tirewear can be corrected by rotatingthe tires.

How Temperature Affects Your TirePressure
The tire pressure monitoring systemmonitors tire pressure in each pneumatictire. When driving in a normal manner, atypical passenger tire inflation pressuremay increase about 2–4 psi (14–28 kPa)from a cold start situation. If the vehicle isstationary overnight with the outsidetemperature significantly lower than thedaytime temperature, the tire pressure maydecrease about 3 psi (21 kPa) for a drop of30°F (17°C) in ambient temperature. Thislower pressure value may be detected bythe tire pressure monitoring system asbeing significantly lower than therecommended inflation pressure andactivate the system warning light for lowtire pressure. If the low tire pressurewarning light is on, visually check each tireto verify that no tire is flat. If one or moretires are flat, repair as necessary. Checkthe air pressure in the road tires. If any tireis under-inflated, carefully drive the vehicleto the nearest location where air can beadded to the tires. Inflate all the tires tothe recommended inflation pressure.
Tire Pressure Monitoring System ResetProcedure
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance CertificationLabel (on the door hinge pillar,door-latch post or the door edge thatmeets the door-latch post, next to thedriver seat) or the Tire Label on theB-Pillar or the edge of the driver door.
Note:You need to perform the tire pressuremonitoring system reset procedure aftereach tire rotation.
To provide the vehicle's load carryingcapability, some vehicles require differentrecommended tire pressures in the fronttires as compared to the rear tires. The tirepressure monitoring system on thesevehicles illuminate the low tire pressurewarning light at two different pressures:one for the front tires and one for the reartires.
Since tires need to be rotated to provideconsistent performance and maximum tirelife, the tire pressure monitoring systemneeds to know when the tires are rotatedto determine which set of tires are on thefront and which are on the rear. With thisinformation, the system can detect andproperly warn of low tire pressures.
System reset tips:
•To reduce the chances of interferencefrom another vehicle, perform thesystem reset procedure at least 3 ft(1 m) away from another vehicleundergoing the system reset procedureat the same time.
•Do not wait more than two minutesbetween resetting each tire sensor orthe system can time-out and you haveto repeat the entire procedure on allfour wheels.
•A double horn sounds indicating theneed to repeat the procedure.
Performing the System Reset Procedure- Single Rear Wheel
Read the entire procedure beforeattempting.
1.Drive the vehicle above 20 mph(32 km/h) for at least two minutes,then park in a safe location where youcan easily get to all four tires and haveaccess to an air pump.

3.Cycle the ignition to the on positionwith the engine off.
4.Turn the hazard flashers on then offthree times. You must accomplish thiswithin 10 seconds. If you successfullyenter the reset mode, the horn soundsonce, the system indicator flashes anda message shows in the informationdisplay. If this does not occur, pleasetry again starting at step 2. If afterrepeated attempts to enter the resetmode, the horn does not sound, thesystem indicator does not flash and nomessage shows in the informationdisplay, have the system checked assoon as possible.
5.Train the tire pressure monitoringsystem sensors in the tires using thefollowing system reset sequencestarting with the left front tire in thefollowing clockwise order: Left front -driver side front tire, Right front -passenger side front tire, Right rear -passenger side rear tire, Left rear -driver side rear tire.
6.Remove the valve cap from the valvestem on the left front tire. Decrease theair pressure until the horn sounds.
Note:The single horn tone confirms thatthe sensor identification code has beenlearned by the module for this position. Ifyou hear a double horn, the reset procedurewas unsuccessful, and you must repeat it.
7.Remove the valve cap from the valvestem on the right front tire. Decreasethe air pressure until the horn sounds.
8.Remove the valve cap from the valvestem on the right rear tire. Decrease theair pressure until the horn sounds.
9.Remove the valve cap from the valvestem on the left rear tire. Decrease theair pressure until the horn sounds.Training is complete after the hornsounds for the last tire trained, driverside rear tire, the system indicatorstops flashing, and a message showsin the information display.
10.Turn the ignition off. If you hear twoshort tones, the reset procedure wasunsuccessful and you must repeat it.If you hear two short beeps when theignition is off after repeating theprocedure, have the system checkedas soon as possible
11.Set all four tires to the recommendedair pressure as indicated on theSafety Compliance CertificationLabel, affixed to either the door hingepillar, door-latch post, or the dooredge that meets the door-latch post,next to the driver seating position orTire Label located on the B-Pillar orthe edge of the driver door.
