Add oil O.K.
With the hybrid system at operating
temperature and turned off, check the
oil level on the dipstick.
1. To get a true reading, the vehicle
should be on a level spot. After turning
off the hybrid system, wait a few min-
utes for the oil to drain back into the
bottom of the engine.
2. Pull the dipstick out, hold the rag un-
der the end and wipe it clean.
3. Reinsert the dipstick—push it in as far
as it will go, or the reading will not be
correct.

4. Pull the dipstick out and look at the oil
level while holding a rag under the
end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
Too full
NOTICE
Be careful not to drop the engine oil
on the vehicle components.
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick. We recommend that you use
a funnel when adding oil.
The approximate quantity of oil needed to
fill between the low level and the full level
on the dipstick is indicated below for ref-
erence.
When the level reaches within the correct
range, install the filler cap hand–tight.
Oil quantity, L (qt., Imp. qt.):

NOTICE
z Be careful not to spill the engine
oil on the vehicle components.
z Avoid overfilling, or the hybrid sys-
tem could be damaged.
z Check the oil level on the dipstick
once again after adding the oil.
