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 282).
6. Remove the dipstick and wipe it with aclean, lint-free cloth. See Under HoodOverview (page 284).
7.Replace the dipstick and remove it againto check the oil level. See Under HoodOverview (page 284).
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 355).
9. If the oil level is correct, replace thedipstick and make sure it is fully seated.
Note:Do not remove the dipstick when theengine is running.
Note: If the oil level is between themaximum and minimum marks, the oil levelis acceptable. Do not add oil.
Note:The oil consumption of new enginesreaches its normal level after approximately3,000 mi (5,000 km).
Adding Engine Oil
WARNING: Do not remove the fillercap when the engine is running.
Do not use supplemental engine oil additivesbecause they are unnecessary and couldlead to engine damage that may not becovered by the vehicle Warranty.

How Fail-Safe Cooling Works
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates and amessage may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs, your vehicle still operates,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, you canre-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for useduring emergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, your vehicle willhave limited power, will not be able tomaintain high-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.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir cap witha thick cloth to prevent the possibility ofscalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
Your vehicle has limited engine power whenin the fail-safe mode, drive your vehicle withcaution. Your vehicle does not maintainhigh-speed operation and the engine mayoperate 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 recommend thatyou contact your roadside assistanceservice provider.
3. If this is not possible, wait for a shortperiod of time 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, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.

Maintenance

Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and the vehiclemay not be able to accelerate with fullpower until the coolant temperaturereduces.
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 stop your vehicle. You cancontinue to drive.
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.Stop your vehicle as soon as it is safe todo so. Fully apply the parking brake, shiftinto park (P) or neutral (N).
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
Do not use supplemental transmission fluidadditives because they are unnecessary andcould lead to transmission damage that maynot be covered by the vehicle Warranty.
The transmission does not consume fluid.However, if the transmission slips or shiftsslowly you should check the fluid level. If younotice a sign of leaking fluid, contact anauthorized dealer.
