STARTING AND STOPPING
THE ENGINE – PRECAUTIONS
WARNING: Extended idling at highengine speeds can produce very hightemperatures in the engine and exhaustsystem, creating the risk of fire or otherdamage.
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: Do not start the enginein a closed garage or in other enclosedareas. Exhaust fumes are toxic. Alwaysopen the garage door before you startthe engine. Failure to follow thisinstruction could result in personal injuryor death.
WARNING: Do not use startingfluid, for example ether, in the air intakesystem. Such fluid could causeimmediate explosive damage to theengine and possible personal injury.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
Note:If you use your vehicle regularly abovethe altitude of 7,500 ft (2,286 m) and underthe temperature of -4.0°F (-20°C), it isrecommended to use the alternative engineoil. See Capacities and Specifications(page 463).
If you stop your vehicle and leave theengine idling for long periods, werecommend that you do one of thefollowing:
•Open the windows at least 1 in(2.5 cm).
•Set your climate control to outside air.
IGNITION SWITCH (IF EQUIPPED)
Switching the Ignition Off
Turn the key to position 0.
Switching the Ignition toAccessory Mode
Turn the key to position I. Electricalaccessories, for example the radio, operatewithout the engine running.

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 463).
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 465).
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 539).
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.

•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.
