Checking Engine Oil
It is a good idea to check the 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.
SeeEngine Compartment Overview on page 5-14
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
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.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-14for
the location of the engine air cleaner/lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change after
each 50,000 mile (80 000 km) interval. SeeScheduled
Maintenance on page 6-4for more information.
If you are driving in dusty/dirty conditions, inspect
the lter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/lter, remove the lter
from the vehicle and lightly shake the lter to release
loose dust and dirt. If the lter remains caked with dirt,
a new lter is required.To inspect or replace the lter, do the following:
1. Loosen and remove the two screws on the top of
the engine air cleaner/lter cover.
2. Lift up the outboard side of the cover at an angle
while pulling toward you. This is necessary due
to the two hinges located on the inboard side of
the cover.
3. Remove the engine air cleaner/lter element and
any loose debris that may be found in the air
cleaner base.
4. Inspect or replace the air lter element.
