CHECKING THE ENGINE OIL LEVEL
1.Make sure that your vehicle is on levelground.
2.Check the oil level before starting theengine, or switch the engine off afterwarm up and wait 15 minutes for theoil to drain into the oil pan.
Note:Checking the oil level too soon couldresult in an inaccurate reading.
3.Remove the dipstick and wipe it witha clean, lint-free cloth.
4.Reinstall the dipstick and make sure itis fully seated.
5.Remove the dipstick again to check theoil level.
Note: If the oil level is between themaximum and minimum marks, the oil levelis acceptable. Do not add oil.
6.If the oil level is at the minimum mark,immediately add oil.
7.Reinstall the dipstick. Make sure it isfully seated.
Note:The oil consumption of new enginesreaches its normal level after approximately3,000 mi (5,000 km).
Note:Increases in oil level can occur fromfrequent short trips that do not allow theengine to get to operating temperature, aswell as frequent idling or low speed drivingfor long periods of time.
Note:If oil levels are continuously notedabove the maximum mark, schedule a visitto your authorized dealer.
ADDING ENGINE OIL
WARNING: Do not remove the fillercap when the engine is running.
WARNING: Do not add engine oilwhen the engine is hot. Failure to followthis instruction could result in personalinjury.
Do not use supplemental engine oiladditives because they are unnecessaryand could lead to engine damage that thevehicle warranty may not cover.
1.Clean the area surrounding the engineoil filler cap before you remove it.
2.Remove the engine oil filler cap.
3.Add engine oil that meets ourspecifications. See Capacities andSpecifications (page 461).
4.Reinstall the engine oil filler cap. Turnit clockwise until you feel a strongresistance.
Note: Do not add oil further than themaximum mark. Oil levels above themaximum mark may cause engine damage.
Note:Immediately soak up any oil spillagewith an absorbent cloth.

ENGINE OIL CAPACITY ANDSPECIFICATION
For filling information, please refer to theCapacities and Specifications section ofyour owner's manual. See Engine OilCapacity and Specification (page 467).
CHECKING THE COOLANT
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 528).
Note:Make sure that the coolant level isbetween the minimum and maximum markson the coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Keep your hands andclothing clear of the cooling fan.

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 capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact 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 predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 461). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and couldvoid the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionized ordistilled water. See Capacities andSpecifications (page 461). Using water thathas not been deionized may contribute todeposit formation, corrosion and pluggingof the small cooling system passageways.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add enough prediluted coolant toreach the 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 step2.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
In case of emergency, you can add a largeamount of water without engine coolantin order to reach a vehicle service location.Service your vehicle as soon as possible.
