10-8 Vehicle Care
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a yellow
loop. See Engine Compartment
Overview on page 10 6 for the
location of the engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running
recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking your oil level too soon
after engine shut off will not
provide an accurate oil level
reading.
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.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick, add
one liter/quart of the recommended
oil and then recheck the level. See
Selecting the Right Engine Oil for
an explanation of what kind of oil to
use. For engine oil crankcase
capacity, see Capacities and
Specifications on page 12 2.
Notice: Do not add too much oil.
Oil levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If you find that you
I n f o r ma t i o n P r o v i d e d b y :
have an oil level above the
operating range, i.e. the engine
has so much oil that the oil level
gets above the cross-hatched
area that shows the proper
operating range, the engine could
be damaged. You should drain
out the excess oil or limit your
driving of the vehicle and seek a
service professional to remove
the excess amount of oil.
See Engine Compartment Overview
on page 10 6 for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
