Engine Oil
Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel ll. 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.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done, 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
Notice:If you spray water into the engine air
cleaner/lter intake and water enters the engine air
cleaner/lter housing, as shown in the illustration,
you could damage your vehicle’s engine. The repairs
would not be covered by your warranty. Do not
spray water into the engine air cleaner/lter intake
and/or housing.SeeEngine Compartment
Overview on page 5-14for
the location of the engine
air cleaner/lter and the air
lter restriction indicator,
if equipped.
When to Inspect the Engine Air
Cleaner/Filter
If the vehicle is equipped with an air lter restriction
indicator, it lets you know when the engine air cleaner/
lter needs to be replaced. On vehicles with a restriction
indicator, you should inspect the air lter restriction
indicator at every oil change and replace the engine air
cleaner/lter when the indicator tells you to.
On vehicles without an air lter restriction indicator, you
should inspect the air cleaner/lter at every oil change
and replace it at the rst oil change after 100,000 miles
(160 000 km). SeeScheduled Maintenance on
page 6-4for more information.

How to Inspect the Engine Air
Cleaner/Filter
Vehicles With an Air Filter Restriction
Indicator
Locate the air lter restriction indicator on the engine
air duct. When the indicator turns black or is in the
red/orange change zone, replace the lter and reset the
indicator. See “Inspecting the Engine Air Cleaner/Filter
and Resetting the Air Filter Restriction Indicator” later in
this section for further instructions.
Vehicles Without an Air Filter Restriction
Indicator
To inspect the air cleaner/lter, remove it from the
vehicle and lightly shake the lter to release loose dust
and dirt. If the engine air cleaner/lter remains caked
with dirt, a new lter is required. See “Inspecting
the Engine Air Cleaner/Filter and Resetting the Air Filter
Restriction Indicator” later in this section for further
instructions.
Inspecting the Engine Air Cleaner/Filter
and Resetting the Air Filter Restriction
Indicator
1. Loosen the screws on the engine air cleaner/lter
cover.
