CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check the
oil level. It should be between the H (High)
and L (Low) marksOB. This is the normal
operating oil level range. If the oil level is
below the L (Low) mark
OA, remove the oil
filler cap and pour recommended oil
through the opening. Do not fill oil level
above H (High) mark
OC.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil main-
tenance intervals or during the break-in pe-
riod, depending on the severity of operating
conditions.
CAUTION
Oil level should be checked regularly. Oper-
ating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
CHANGING ENGINE OIL AND OIL
FILTER
For additional information on engine oil and
oil filter change, refer to the instructions out-
lined in this section.
Vehicle set-up
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3.
Turn the engine off and wait for 15 minutes.
4. Raise and support the vehicle using a suit- able floor jack and safety jack stands.
• Place the safety jack stands under the ve- hicle jack-up points.
• A suitable adapter should be attached to the jack stand saddle.
