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.

If you feel a sudden vibration or ridedisturbance while driving, or you suspectyour tire or vehicle has been damaged,immediately reduce your speed. Drivewith caution until you can safely pull offthe road. Stop and inspect the tires fordamage. If a tire is under-inflated ordamaged, deflate it, remove the wheeland replace it with your spare tire andwheel. If you cannot detect a cause,have the vehicle towed to the nearestrepair facility or tire dealer to have thevehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or potholecan cause the front end of your vehicleto become misaligned or cause damageto your tires. If your vehicle seems topull to one side when you are driving,the wheels could be out of alignment.Have an authorized dealer check thewheel alignment periodically.
Wheel misalignment in the front or therear can cause uneven and rapidtreadwear of your tires and should becorrected by an authorized dealer.
INSPECTING THE WHEEL VALVE
STEMS
Check the valve stems for holes, cracks,or cuts that could permit air leakage.
TIRE ROTATION
WARNING: If the tire label showsdifferent tire pressures for the front andrear tires and the vehicle has a tirepressure monitoring system, then you needto update the settings for the systemsensors. Always perform the system resetprocedure after tire rotation. If you do notreset the system, it may not provide a lowtire pressure warning when necessary.
Rotating your tires at the recommendedinterval will help your tires wear more evenly,providing better tire performance and longertire life.
Note:If your tires show any uneven wearhave the alignment checked by anauthorized dealer before rotating tires.
Note:If you have a dissimilar spare wheeland tire assembly, it is intended fortemporary use only and should not be usedin a tire rotation.
Note:After having your tires rotated, inflationpressure must be checked and adjusted tothe vehicle requirements.
