If the CHECK OIL LEVEL message appears on the
instrument cluster, it means you need to check
your engine oil level right away.
For more information, see “CHECK OIL LEVEL” under
DIC Warnings and Messages on page 3-68.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is 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 handle is a yellow loop. See
Engine Compartment Overview on page 5-14for
the location of the engine oil dipstick.
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.

Engine Air Cleaner/Filter
SeeEngine Compartment
Overview on page 5-14for
location of engine air
cleaner/lter and change
indicator (if equipped).
When to Inspect
If your vehicle is equipped with a lter change indicator
it lets you know when the lter needs to be replaced.
Vehicles with a restriction indicator, inspect the air
cleaner/lter at every oil change and replace the lter
when the indicator tells you to. Vehicles without a
change indicator, inspect the air cleaner/lter at every
oil change and replace it at the rst oil change after
25,000 miles (40 000 km).
How to Inspect
Locate the lter change indicator. When the change
indicator turns black or is in the red/orange “change”
zone, replace the lter and reset the indicator. To inspect
the air cleaner/lter, remove the lter from the vehicle and
lightly shake lter to release loose dust and dirt. If the
lter remains “caked” with dirt, a new lter is required.
To inspect and replace the lter and reset the indicator
(if equipped), do the following:
The air cleaner/lter assembly is located on the front
corner of the engine compartment on the passenger’s
side of the vehicle.

After rell, the level must be rechecked. Add enough engine oil so that the uid is within the proper operating range.
