If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
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 vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andambient temperature. If this occurs, there isno need to pull off the road. You cancontinue to drive your vehicle.
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,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 after severalminutes, follow the remaining steps.
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, restart theengine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
6F35/HF35 transmission (If Equipped)
Note:Transmission fluid should be checkedby an authorized dealer. If required, fluidshould be added by an authorized dealer.
The automatic transmission does not havea transmission fluid dipstick.
Refer to your scheduled maintenanceinformation for scheduled intervals for fluidchecks and changes. Your transmission doesnot consume fluid. However, the fluid levelshould be checked if the transmission is notworking properly, (For example: if thetransmission slips or shifts slowly) or if younotice some sign of fluid leakage. SeeScheduled Maintenance (page 509).
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.

Checking the fluid level
Low fluid level
If the fluid level is below the MIN range ofthe dipstick, add fluid to reach the hash marklevel.
Note:If the fluid level is below the MIN level,do not drive the vehicle. An underfillcondition may cause shift or engagementconcerns or possible damage.
Correct fluid level
The transmission fluid should be checked atnormal operating temperature 180°F-200°F(82°C-93°C) on a level surface. The normaloperating temperature can be reached afterapproximately 20 miles (30 kilometers) ofdriving.
The transmission fluid level should betargeted within the cross-hatch area if atnormal operating temperature 180°F-200°F(82°C-93°C).
High fluid level
If the fluid level is above the MAX range ofthe dipstick, remove fluid to reach thehashmark level.
Note:Fluid level above the MAX level maycause shift or engagement concerns orpossible damage. High fluid levels can becaused by an overheating condition. If yourvehicle has been operated for an extendedperiod at high speeds, in city traffic duringhot weather or pulling a trailer, the vehicleshould be turned off until normal operatingtemperatures are reached.
