WARNING: Do not allow the fluid totouch your skin or eyes. If this happens,rinse the affected areas immediately withplenty of water and contact your physician.
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.
Note:Automotive fluids are notinterchangeable.
It is very important to use prediluted coolantapproved to the correct specification in orderto avoid plugging the small passageways inthe engine cooling system. See Capacitiesand Specifications (page 408). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engine orcooling system components and could voidthe vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionized or distilledwater. See Capacities and Specifications(page 408). Using water that has not beendeionized may contribute to depositformation, corrosion and plugging of thesmall cooling system passageways.
To top up the coolant level do the following:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add enough prediluted coolant to reachthe correct level.
Note:We do not recommend the use ofrecycled coolant.
3.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
4.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, repeat step 2.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have your vehiclechecked as soon as possible. Operating anengine with a low level of coolant can resultin engine overheating and possible enginedamage.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location.Service your vehicle as soon as possible.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute, as they can cause engine damagefrom overheating or freezing:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection of thecoolant.

Severe Climates
If you drive in extremely cold climates, youmay need to increase the coolantconcentration above 50%.
Note:A coolant concentration of 60%provides improved freeze point protection.Coolant concentrations above 60% decreasethe overheat protection characteristics ofthe coolant and could cause enginedamage.
If you drive in extremely hot climates, youmay need to decrease the coolantconcentration to 40%.
Note:A coolant concentration of 40%provides improved overheat protection.Coolant concentrations below 40% decreasethe overheat and corrosion protectioncharacteristics of the coolant and couldcause engine damage.
Coolant Change
WARNING: Do not dispose of coolantin the household refuse or the publicsewage system. Use an authorized wastedisposal facility.
Change the coolant at specific mileageintervals. Refer to the scheduledmaintenance information. See NormalScheduled Maintenance (page 474).
Note:Dispose of used coolant in theappropriate manner.
Follow your community's regulations andstandards for recycling and disposing ofautomotive fluids.
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
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stop withoutwarning. Failure to follow this instructioncould result in the loss of control of yourvehicle.
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.

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.
ENGINE AIR FILTER
CHANGING THE ENGINE AIR FILTER -2.0L
WARNING: To reduce the risk ofvehicle damage and personal burn injuries,do not start your engine with the aircleaner removed and do not remove itwhile the engine is running.
Change the air filter element at the properintervals.
When changing the air filter element, useonly the air filter element listed. SeeCapacities and Specifications (page 408).
Note:Failure to use the correct air filterelement could result in severe enginedamage that the vehicle warranty may notcover.
Note: When servicing the air filter, do notallow foreign material to enter the airinduction system. The engine is susceptibleto damage from even small particles.

Tips for use of the kit
To make sure the kit operates safely andproperly, observe the following:
•Before operating the kit, make sure yourvehicle is safely off the road and awayfrom moving traffic.
•Do not remove any foreign objects, suchas nails or screws, from the tire.
•Do not allow the compressor to operatecontinuously for more than 15 minutes.This prevents the compressor fromoverheating.
•Only use the kit when the ambienttemperature is between -22°F (-30°C) and158°F (70°C).
•Only use the sealing compound beforethe use-by date. The use-by date is on alabel on the sealant canister and can beseen through the rectangular viewingwindow on the bottom of the compressor.Check the use-by date regularly andreplace the canister when the sealantexpires.
Note:Sealant compound contains latex. Useappropriate precautions to avoid any allergicreactions.
When inflation only is required fora tire or other objects, the selectormust be in the Air position.

If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval at sixmonths or 5,000 mi (8,000 km) from yourlast oil change. Never exceed one year or10,000 mi (16,000 km) between oil changeintervals.
You can drive your vehicle in such a way thatmay lead to higher oil consumption includingextended time at high engine speeds, highloads, engine braking, hard corneringmaneuvers, track and off-road usage. Underthese conditions, oil consumption ofapproximately 1 quart per 500 miles (1 literper 800 km) is possible. Check the engineoil level at every refueling and adjust tomaintain proper levels to avoid enginedamage.
You can also drive your vehicle in such a waythat dilutes and increases the level of oil byfrequent short trips that do not allow theengine to get to operating temperature,extended idling and low speed driving forlong periods of time.
It is important to rely upon your dealershipto properly diagnose and repair your vehicle.
We strongly recommend only using ourgenuine or our authorized re-manufacturedreplacement parts engineered for yourvehicle.
Additives and Chemicals
We do not recommend using chemicals oradditives not approved by us as part of yourvehicle’s normal maintenance. Please consultyour warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normaloperating characteristic and, by itself, doesnot necessarily indicate a concern or that thefluid needs to be changed. Have discoloredfluids that also show signs of overheating orforeign material contamination checkedimmediately.
Make sure to change the vehicle’s oils andfluids at the specified intervals or inconjunction with a repair. Flushing is a viableway to change fluid for many vehiclesub-systems during scheduled maintenance.It is critical that systems are flushed only withnew fluid that is the same as that requiredto fill and operate the system or using ourapproved flushing chemical.
Owner Checks and Services
Make sure you perform the following basicmaintenance checks and inspections.
