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).

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.

•If vehicles are stored outside, theyrequire regular maintenance to protectagainst rust and weather damage.
•Make sure all linkages, cables, leversand pins under your vehicle are coveredwith grease to prevent rust.
•Move vehicles at least 25 ft (7.5 m)every 15 days to lubricate working partsand prevent corrosion.
•Fill the fuel tank with high-quality fueluntil the first automatic shutoff of thefuel pump nozzle.
Engine
•Change the engine oil and filter prior tostorage because used engine oilcontains contaminants which maycause engine damage.
•Start the engine every 15 days for aminimum of 15 minutes. Run at fastidle with the climate controls set todefrost until the engine reaches normaloperating temperature.
•With your foot on the brake, shiftthrough all the gears while the engineis running.

Why Maintain Your Vehicle at YourDealership?
Our Genuine Replacement Parts
Dealerships stock our parts and ourauthorized branded remanufacturedreplacement parts. These parts meet orexceed our specifications. Parts installedat your dealership carry a nationwide24-month or unlimited mile (kilometer)parts and labor limited warranty.
If you do not use our authorized parts, theymay not meet our specifications and couldaffect emissions compliance.
Protecting Your Investment
Maintenance is an investment that paysdividends in the form of improvedreliability, durability and resale value. Tomaintain the proper performance of yourvehicle and its emission control systems,make sure you have scheduledmaintenance performed at the designatedintervals.
Your vehicle comes with the IntelligentOil-Life Monitor system, a messageappears in the instrument cluster displayat the proper oil change interval. Thisinterval may be up to one year or 10,000 mi(16,000 km), hybrid vehicles could exceed10,000 mi (16,000 km).
When the oil change message appears inthe instrument cluster display, it is time foran oil change. Make sure you perform theoil change within two weeks or 500 mi(800 km) of the message appearing. Makesure to reset the Intelligent Oil-Life Monitorafter each oil change. See Resetting theIntelligent Oil Life Monitor (page 355).
If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval atsix months or 5,000 mi (8,000 km) fromyour last oil change. Never exceed one yearor 10,000 mi (16,000 km) between oilchange intervals.
You can drive your vehicle in such a waythat may lead to higher oil consumptionincluding extended time at high enginespeeds, high loads, engine braking, hardcornering maneuvers, track and off-roadusage. Under these conditions, oilconsumption of approximately 1 quart per500 miles (1 liter per 800 km) is possible.Check the engine oil level at every refuelingand adjust to maintain proper levels toavoid engine damage.
