•You hold the vehicle at a stopcontinuously for more than three minutes.
Hilly Condition Usage
You should select a lower gear when thesystem is active in situations such asprolonged downhill driving on steep grades,for example in mountainous areas. Thesystem needs additional engine braking inthese situations to reduce the load on thevehicle’s regular brake system to prevent itfrom overheating.
Note:An audible alarm sounds and thesystem shuts down if it applies brakes for anextended period of time. This allows thebrakes to cool. The system functionsnormally again after the brakes cool.
Switching Adaptive Cruise Control Off

STEERING
Electric Power Steering
WARNING: The electric power steeringsystem has diagnostic checks thatcontinuously monitor the system. If a fault isdetected, a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. Switch the ignitionoff. After at least 10 seconds, switch theignition on and watch the information displayfor a steering system warning message. If asteering system warning message returns,have the system checked by an authorizeddealer.
WARNING: If the system detects anerror, you may not feel a difference in thesteering, however a serious condition mayexist. Obtain immediate service from anauthorized dealer, failure to do so may resultin loss of steering control.
Your vehicle has an electric power steeringsystem. There is no fluid reservoir. Nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage to thesteering system. You do not lose the abilityto steer your vehicle manually. Typicalsteering and driving maneuvers allow thesystem to cool and return to normaloperation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspension components.
•Loose or worn steering components.
•Improper vehicle alignment.

Driving Aids

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.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection of thecoolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling process isnot yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity's regulations and standards forrecycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60% providesimproved freeze point protection. Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and maycause engine damage.
If you drive in extremely hot climates:
•It may be necessary to decrease thecoolant concentration to 40%.
•A coolant concentration of 40% providesimproved overheat protection. Coolantconcentrations below 40% decrease thefreeze and corrosion protectioncharacteristics of the coolant and maycause engine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambient temperature,vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the coolanttemperature gauge moves toward the redzone:

Maintenance

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

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).
