ENGINE COOLANT CHECK
WARNINGS
Never remove the coolant reservoircap when the engine is running or hot.
Do not put coolant in the windshieldwasher reservoir. If sprayed on thewindshield, coolant could make it difficult tosee through the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressure relief cap.The cooling system is under pressure. Steamand hot liquid can come out forcefully whenyou loosen the cap slightly.
WARNINGS
Do not add coolant further than theMAX mark.
When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 509).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -30°F (-34°C) and -34°F (-37°C).Coolant concentration should be checkedusing a refractometer. We recommend,Robinair® Coolant and Battery Refractometer75240 (Rotunda tool part number:ROB75240). We do not recommend the useof hydrometers or coolant test strips formeasuring coolant concentration.

Maintenance

Note:Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
Adding Coolant
WARNINGS
Do not add engine coolant when theengine is hot. Failure to follow thisinstruction could result in personal injury.
Never remove the coolant reservoircap when the engine is running or hot.
It is very important to use prediluted coolantmeeting the correct specification in order toavoid plugging the small passageways in theengine cooling system. See Capacities andSpecifications (page 380). Incorrectprediluted coolant use can cause damagenot covered by the vehicle Warranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant meeting thecorrect specification. See Capacities andSpecifications (page 373).
3.Add enough prediluted coolant to reachthe correct level.
4. Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
Do not mix different colors or types ofprediluted coolant in your vehicle. Mixing ofprediluted coolant or using an incorrectprediluted coolant may harm the engine orcooling system components and may not becovered by the vehicle Warranty.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location. Inthis instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the cooling system.
3. Refill with prediluted coolant as soon aspossible.
Water alone, without prediluted coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.

Maintenance

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
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest in asafe location and seek immediate repairs.When in fail-safe mode, your vehicle will havelimited power, will not be able to maintain
WARNINGS
high-speed operation, and may completelyshut down without warning, potentially losingengine power, power steering assist, andpower brake assist, which may increase thepossibility of a crash resulting in seriousinjury.
Never remove the coolant reservoircap when the engine is running or hot.
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 a short periodfor 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:If this is not possible, wait a shortperiod for the engine to cool.

Maintenance

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.
