ENGINE OIL CHECK
To check the engine oil level consistentlyand accurately, do the following:
1.Make sure the parking brake is on. Makesure the transmission is in park (P) orneutral (N).
2. Run the engine until it reaches normaloperating temperature.
3. Make sure that your vehicle is on levelground.
4.Switch the engine off and wait 15 minutesfor the oil to drain into the oil pan. Checking the engine oil level too soonafter you switch the engine off may resultin an inaccurate reading.
5. Open the hood. See Opening andClosing the Hood (page 297).
6. Remove the dipstick and wipe it with aclean, lint-free cloth. See Under HoodOverview (page 298).
7.Replace the dipstick and remove it againto check the oil level. See Under HoodOverview (page 298).
8. Make sure that the oil level is betweenthe maximum and minimum marks. If theoil level is at the minimum mark, add oilimmediately. See Capacities andSpecifications (page 373).
9. If the oil level is correct, replace thedipstick and make sure it is fully seated.

Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk of crashand injury, be prepared that the vehiclespeed may reduce and the vehicle may notbe able to accelerate with full power until thecoolant temperature reduces.
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 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.

Maintenance

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 notproperly working. For example, if thetransmission slips or shifts slowly or if younotice some sign of fluid leakage. SeeScheduled Maintenance (page 504).
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.
6F55 Transmission (If Equipped)
WARNING: The dipstick andsurrounding components are hot. Use gloveswhen moving components and checking thetransmission fluid level. Failure to follow thiswarning could result in serious personalinjury.
Note:Automatic transmission fluid expandswhen warmed. To obtain an accurate fluidcheck, drive the vehicle until it is warmed up(approximately 20 mph (30 km/h). If yourvehicle has been operated for an extendedperiod at high speeds, in city traffic duringhot weather or pulling a trailer, the vehicleshould be switched off until normal operatingtemperatures are reached to allow the fluidto cool before checking. Depending onvehicle use, cooling times could take up to30 minutes or longer.
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.
1. Drive the vehicle 20 mph (30 km/h) oruntil it reaches normal operatingtemperature
2. Park the vehicle on a level surface andengage the parking brake.
3.With the parking brake engaged and yourfoot on the brake pedal, start the engineand move the gearshift lever through allof the gear ranges. Allow a minimum of10 seconds for each gear to engage.
4. Put the gearshift lever in park (P) andleave the engine running.
Note:You will need to move the air filterassembly to access the transmissiondipstick.
5.Remove the dipstick, wiping it clean witha clean, dry lint free rag. If necessary,refer to Under hood overview in thischapter for the location of the dipstick.
6. Install the dipstick making sure it is fullyseated in the filler tube by turning it tothe locked position.
7.Remove the dipstick and inspect the fluidlevel. The fluid should be in thedesignated areas for normal operatingtemperature.

8.Rotate the air filter assembly 90 degreescounterclockwise and reinstall into therubber hose.
9. Tighten the clamp (A).
10. The transmission fluid level indicatorcan now be accessed.
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 mph (30 km/h) of driving.
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 switched off until normal operatingtemperatures are reached. Depending onvehicle use, cooling times could take up to30 minutes or longer.
Adjusting Automatic Transmission FluidLevels
Before adding any fluid, make sure thecorrect type is used. The type of fluid usedis normally indicated on the dipstick and alsoin the Technical Specifications section in thischapter.
Note:An overfill condition of transmissionfluid may cause shift or engagementconcerns or possible damage.
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.Reinstall the air filter assembly. After the fluidlevel has been checked and adjusted asnecessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filterassembly to the rubber hose.
3.Rotate the air filter assembly 90 degreesclockwise without disconnecting thesensor.
4.Seat the air filter assembly back into thegrommets by pushing down on the airfilter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that attachair filter assembly to the front of thevehicle.
7. Install the bolt cover (if equipped).
