When jacking up your vehicle with the
jack, position the jack correctly as
shown in the illustrations.
CAUTION
When jacking, be sure to observe the
following to reduce the possibility of
personal injury:
Follow jacking instructions.
Do not put any part of your body
under the vehicle supported by the
jack. Personal injury may occur.
Do not start the hybrid system
while your vehicle is supported by
the jack.
Stop the vehicle on a level firm
ground, firmly set the parking brake
and put the hybrid transmission in
“P”. Block the wheels on the oppo-
site side of the jack up point if
necessary.
Make sure to set the jack properly
in the jack point. Raising the ve-
hicle with jack improperly posi-
tioned will damage the vehicle or
may allow the vehicle to fall off the
jack and cause personal injury.
Never get under the vehicle when
the vehicle is supported by the jack
alone; use vehicle support stands.
Do not raise the vehicle with some-
one in the vehicle.
When raising the vehicle, do not
place any objects on top of or un-
derneath the jack.
NOTICE
Make sure to place the jack correctly,
or your vehicle may be damaged.
Here is a list of parts and tools you will
need to perform do−it−yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.

“Toyota Genuine Motor Oil” or equiva-
lent
See page 386 in Section 7− 2 for de-
tails about engine oil selection.
Tools:

Low level Full level
Add oil O.K. Too full
With the hybrid system at operating
temperature and turned off, check the
oil level on the dipstick. 1. To get a correct reading, the vehicle should be on level ground. 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 a rag under 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.
NOTICE
Be careful not to drop engine oil on
the vehicle components.
 To avoid drops of the engine oil
falling when you pull out the engine
oil dipstick, make sure to hold a
rag under the dipstick.
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
raise the level between low and full on the
dipstick is indicated as follows:
1.5 L (1.6 qt., 1.3 lmp. qt.)
For the engine oil capacity, see “Service
specifications” on page 412 in Section 8. When the level reaches within the correct
range, install the filler cap hand−
tight.
NOTICE
Be careful not to spill engine oil on
the vehicle components.
 Avoid overfilling, or the engine
could be damaged.
 Check the oil level on the dipstick
once again after adding the oil.
