Checking Engine Oil
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.The engine oil dipstick has
a yellow handle and is
located near the center of
the engine compartment.
SeeEngine Compartment
Overview on page 5-12
for more information
on location.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.
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.

What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don’t 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, pouring it on the ground, into sewers,
or into streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil. If you have
a problem properly disposing of your used oil, ask your
dealer, a service station or a local recycling center
for help.
Engine Air Cleaner/Filter
SeeEngine Compartment
Overview on page 5-12
for the location of the
engine air cleaner/filter
and change indicator
(if equipped).
When to Inspect the Engine Air
Cleaner/Filter
If your vehicle is equipped with afilter change indicator
it will let you know when thefilter needs to be replaced.
When the change indicator turns black or is in the
red/orange change zone, change thefilter and reset the
indicator. Vehicles without a change indicator inspect the
air cleaner/filter every 15,000 miles (25 000 km) and
replace thefilter every 30,000 miles (50 000 km). If you
are driving in dusty/dirty conditions, inspect thefilter or
change indicator at each engine oil change.

It is also important to check your oil regularly and keep
it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. SeeEngine Oil on
page 5-13for information on resetting the system.
