WARNING: The fuel system maybe under pressure. If you hear a hissingsound near the fuel filler inlet, do notrefuel until the sound stops. Otherwise,fuel may spray out, which could causeserious personal injury.
WARNING: Keep children awayfrom the fuel pump. Never let childrenpump fuel.
WARNING: Do not pry open thefuel tank filler valve. This could damagethe fuel system. Failure to follow thisinstruction could result in fire, personalinjury or death.
WARNING: Stay outside yourvehicle and do not leave the fuel pumpunattended when refueling your vehicle.
WARNING: Do not remove the fuelpump nozzle from its fully insertedposition when refueling.
WARNING: Stop refueling whenthe fuel pump nozzle automaticallyshuts off for the first time. Failure tofollow this will fill the expansion spacein the fuel tank and could lead to fueloverflowing.
WARNING: Do not overfill the fueltank. The pressure in an overfilled tankmay cause leakage and lead to fuel sprayand fire.
WARNING: Wait at least fiveseconds before removing the fuel pumpnozzle to allow any residual fuel to draininto the fuel tank.
1.Fully open the fuel filler door.
2.Remove the fuel filler cap by turning itcounterclockwise.
3.Select the correct fuel pump nozzle foryour vehicle.
4.Insert the fuel pump nozzle up to thefirst notch. Keep the fuel pump nozzleresting on the fuel tank filler pipe.

WARNING: Tampering with ordisabling the selective catalyticreduction system results in severevehicle performance limitation includingeventual speed limiting to 5 mph(8 km/h).
Note: Do not put diesel exhaust fluid in thefuel tank. Do not start the engine if anyamount of diesel exhaust fluid was addedto the diesel fuel tank as it will likely lead tofailure of the fuel pump and injectors andmay result in severe engine damage whichyour vehicle Warranty may not cover. Thediesel fuel tank must be completely drainedand cleaned prior to being refilled with cleandiesel fuel and starting the engine.
Selective catalytic reduction systems aresensitive to contamination of the dieselexhaust fluid. Maintaining the purity of thefluid is important to avoid systemmalfunctions. If you remove or drain thediesel exhaust fluid tank, do not use thesame fluid to refill the tank. The systemhas a sensor to monitor fluid quality.
Driving without refilling, replacingcontaminated diesel exhaust fluid, orhaving the selective catalytic reductionsystem repaired results in the followingactions as required by the California AirResources Board (CARB) and the U.S.Environmental Protection Agency (EPA):
•Within a preset distance to empty,speed is limited upon vehicle restart.Prior to this occurring a messageappears in the information display.
•Further vehicle operation withoutrefilling or replacing contaminateddiesel exhaust fluid causes the engineto enter an idle-only condition. Thisonly occurs upon vehicle refueling,vehicle idling in park for 1 hour, orengine shutdown for 10 minutes ormore and is indicated by a message inthe information display indicatingrequired actions to resume normaloperation. It is required to add aminimum of 1.0 gal (3.8 L) of dieselexhaust fluid to the tank to exit theidle-only condition, but your vehicle isstill in the speed-limiting mode untilyou refill the tank completely.
Note:For vehicle speed limiting or idle-onlycondition, normal vehicle operation resumeswhen you refill the diesel exhaust fluid tankor repair the contaminated system. If thesystem is contaminated or inoperative, haveyour vehicle checked as soon as possible.

7.Return the container to the verticalposition slightly below the dieselexhaust fluid filler neck.
8.Allow any fluid remaining in the spoutto drain back into the container.
9.Remove the spout from the dieselexhaust fluid filler neck.
10.Replace the diesel exhaust fluid tankcap. Turn it clockwise until you feela strong resistance and it clicks.
11.Remove the spout from the dieselexhaust fluid container and replacethe cap.

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, have your vehiclechecked as soon as possible.
