pan. This will reduce the amount of
oil held in the dry sump tank and
there could be no engine oil on the
dipstick. This is normal since the
dipstick is designed to read the
engine oil level only after the engine
has run long enough to reach
normal operating temperature. Do
not add engine oil based on cold
engine dipstick readings. The
engine oil level on the dipstick must
be checked while the engine is
running at idle.
To check the engine oil:
1. Turn the engine on and let it
warm up to at least 80 °C (175
°F).
2. Once the engine is warm,
check the oil while the engine
is running at idle.

Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
3. Remove the dipstick and wipe
it with a clean lint-free paper
towel or a cloth. Re-insert the
dipstick and push it all the way
in until it stops.
4. Remove the dipstick again and
read the level on the
cross-hatched area.
5. Turn the engine off.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
through the oil fill cap opening in the
oil tank fill tube and then recheck
the level. See “Selecting the Right
Engine Oil” later in this section for
the type of oil to use. For engine oil
crankcase capacity, see Capacities
and Specifications 0 299.
Caution
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 the oil level is
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. Drain
the excess oil or limit driving of
the vehicle, and seek a service
professional to remove the
excess oil.
See Engine Compartment Overview
0 215 for the location of the external
engine oil tank dipstick and fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back into the oil tank tube when
finished.
