A. Oil Fill Cap To remove: 1. Remove the oil fill cap (A). To ensure proper engine performance and long life, careful attention must be
paid to engine oil. Following these simple, but important steps will help protect
your investment: See “Selecting the Right Engine Oil” in this section.
Checking Engine Oil It is a good idea to check the engine oil level at each fuel fill. In order to get an accurate reading, the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview
for the location of the engine oil dipstick. Obtaining an accurate oil level reading is essential: 1. If the engine has been running recently, turn off the engine and allow several
minutes for the oil to drain back into the oil pan. Checking the oil level too soon after engine shutoff will not provide an accurate
oil level reading. 2. Pull out the dipstick and clean it with a paper towel or cloth, then push
it back in all the way. Remove it again, keeping the tip down, and check the level. When to Add Engine Oil If the oil is below the cross-hatched area at the tip of the dipstick, add 1
L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” in this section for an explanation of what
kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications
. Notice: Do not add too much oil. Oil levels above or below the acceptable
operating range shown on the dipstick are harmful to the engine. If you find that
you have an oil level above the operating range, i.e., the engine has so much oil
that the oil level gets above the cross-hatched area that shows the proper operating
range, the engine could be damaged. You should drain out the excess oil or limit
driving of the vehicle and seek a service professional to remove the excess amount
of oil. See Engine Compartment Overview for the location of the engine oil fill
cap. Add enough oil to put the level somewhere in the proper operating range. Push
the dipstick all the way back in when through. Selecting the Right Engine Oil Selecting the right engine oil depends on both the proper oil specification and
viscosity grade. See Recommended Fluids and Lubricants . Specification Use and ask for licensed engine oils with the dexos1™ approved certification
mark. Engine oils meeting the requirements for the vehicle should have the dexos1
approved certification mark. This certification mark indicates that the oil has been approved to the dexos1
specification. Notice: Failure to use the recommended engine oil or equivalent can result
in engine damage not covered by the vehicle warranty. Check with your dealer or
service provider on whether the oil is approved to the dexos1 specification. Viscosity Grade SAE 5W-30 is the best viscosity grade for the vehicle. Do not use other viscosity
grade oils such as SAE 10W-30, 10W-40, or 20W-50. If in an area of extreme cold, where the temperature falls below −20°F (−29°C),
an SAE 0W-30 oil should be used. An oil of this viscosity grade will provide easier
cold starting for the engine at extremely low temperatures. When selecting an oil
of the appropriate viscosity grade, always select an oil that meets the dexos1 specification
or equivalent. See “Specification” for more information. Engine Oil Additives/Engine Oil Flushes Do not add anything to the oil. The recommended oils with the dexos specification and displaying the dexos certification
mark are all that is needed for good performance and engine protection. Engine oil system flushes are not recommended and could cause engine damage not
covered by the vehicle warranty. What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin
and could even cause cancer. Do not let used oil stay on your skin for very long.
Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly
dispose of clothing or rags containing used engine oil. See the manufacturer's warnings
about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure
to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground,
into sewers, or into streams or bodies of water. Recycle it by taking it to a place
that collects used oil. When to Change Engine Oil This vehicle has a computer system that indicates when to change the engine oil
and filter. This is based on a combination of factors which include engine revolutions,
engine temperature, and miles driven. Based on driving conditions, the mileage at which an oil change is indicated
can vary considerably. For the oil life system to work properly, the system must be reset every time
the oil is changed. When the system has calculated that oil life has been diminished, it indicates
that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system
might indicate that an oil change is not necessary for up to a year. The engine
oil and filter must be changed at least once a year and, at this time, the system
must be reset. Your dealer has trained service people who will perform this work
and reset the system. It is also important to check the oil regularly over the course
of an oil drain interval and keep it at the proper level. If the system is ever reset accidentally, the oil must be changed at 5 000 km
(3,000 mi) since the last oil change. Remember to reset the oil life system whenever the oil is changed. How to Reset the Engine Oil Life System Reset the system whenever the engine oil is changed so that the system can calculate
the next engine oil change. To reset the system: 1. Turn the ignition to ON/RUN, with the engine off. Three chimes sound and the CHANGE ENGINE OIL SOON message goes off. 4. Turn the key to LOCK/OFF. If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started,
the engine oil life system has not been reset. Repeat the procedure.Engine Cover
