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.
COOLANT – WARNING LAMPS
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone.
A warning lamp illuminates anda message may appear in theinformation display.

12.Turn the ignition off. If two short hornbeeps are heard, the reset procedurewas unsuccessful and you mustrepeat it. If after repeating theprocedure and two short beeps areheard when the ignition is turned tooff, contact your authorized dealer assoon as possible.
13.Set all six 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.
Trailer Tire Pressure MonitoringSystem (If Equipped)
Note:Additional equipment may berequired for your vehicle to support trailertire pressure and temperature monitoring.See your authorized dealer for moreinformation.
Note:The trailer tire pressure monitoringsystem is not a substitute for proper tiremaintenance. It is your responsibility tomaintain correct tire pressures at all times.
Note:Replace the screw and valve on thetrailer tire pressure sensor anytime the trailertire is repaired, replaced or in for service. Seeyour authorized dealer for details.
The trailer tire pressure monitoring systemis an added safety feature that allows youto view your trailer tire pressures andtemperatures through the instrumentcluster display. See Tire PressureMonitoring System – InformationMessages (page 508). Tire pressuresensors are mounted into each tire on yourtrailer. The sensors send a message to yourvehicle indicating the current trailer tirepressure and temperature.
If the trailer tire pressure monitoringsystem detects that a tire is low, a warningmessage appears in the instrument clusterdisplay. The trailer tire information screenin the instrument cluster display highlightsthe tire with a low pressure.
If the trailer tire pressure monitoringsystem detects that a tire temperature isover temp, a warning message appears inthe instrument cluster display. The trailertire information screen in the instrumentcluster display highlights the tire with ahigh temperature.
The main function of the trailer tirepressure monitoring system is to warn youwhen your trailer tires need air or if the tiresare experiencing high temperatures. It canalso warn you if the system is no longercapable of functioning as intended. SeeTire Pressure Monitoring System –Information Messages (page 508).
When a Temporary Spare or New Tireis Installed
If you have replaced a trailer tire with a newor spare tire, a warning message appearsand pressure readings are no longerdisplayed for that tire.

To restore the full function of the trailertire pressure monitoring system:
•Have the damaged wheel and tireassembly repaired and remounted toyour trailer.
•Install the trailer tire pressuremonitoring sensor into the new wheeland tire assembly.
•Perform the trailer tire pressuremonitoring system reset procedure.
Trailer Tire Pressure MonitoringSystem Reset Procedure
Note:You need to perform the tire pressuremonitoring system reset procedure aftereach tire rotation, or when a new trailer tirepressure sensor is installed into a trailer tire.
The trailer tire pressure monitoring systemcan be reset through the menu in theinstrument cluster display. See TirePressure Monitoring System –Information Messages (page 508).Performing the trailer setup process alsoresets the trailer tire pressure monitoringsystem.
Note:For further information on the trailertire pressure monitoring system see theinstructions that were included with thetrailer tire pressure monitoring system kit.
