Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss of
control and possible injury. Be sure
to consult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking brake
will not hold the vehicle securely.
Make sure you have a proper freeze
protection of coolant.
Your coolant must contain ethyleneglycol
type coolant for a proper corrosion
protection of aluminum components. Use
“Toyota Genuine Long Life Coolant” or
equivalent.
See 217 page in Section 82 for details
about coolant type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about 50°C
(58 °F). Do not use more than 70% solu-
tion for better coolant performance.
Check the condition of the auxiliary
battery and cables.
Cold temperatures reduce the capacity of
any auxiliary battery, so it must be in top
shape to provide enough power for winter
starting. Section 83 tells you how to
visually inspect the auxiliary battery. Your
Toyota dealer will be pleased to check the
level of charge. Make sure the engine oil viscosity is
suitable for the cold weather.
See 215 page in Section 82 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealer—he will be pleased to
help.
Keep the door locks from freezing.
Squirt lock deicer or glycerine into the
locks to keep them from freezing.
Use a washer fluid containing an anti
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer ’s directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute as washer fluid be-
cause it may damage your vehicle’s
paint.

Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer
for information concerning recycling
or disposal.
Take care when filling the brake
fluid reservoir because brake fluid
can harm your eyes and damage
painted surfaces. If fluid gets in
your eyes, flush your eyes with
clean water immediately. If you still
feel uncomfortable with your eyes,
go to the doctor.
NOTICE
Remember that batteries and igni-
tion cable carry high currents or
voltages. Be careful of accidentally
causing a short circuit.
 Add only demineralized or distilled
water to fill the radiator. And if you
spill some of the coolant, be sure
to wash it off with water to prevent
it from damaging the parts or paint.
 Do not allow dirt or anything else
to fall through the spark plug holes.
 Do not pry the outer electrode of
spark plug against the center elec-
trode.
 Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
 If you spill the fluid, be sure to
wash it off with water to prevent it
from damaging the parts or paint.
 Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
Be careful not to scratch the glass
surface with the wiper frame.
 When closing the hood, check to
see that you have not forgotten any
tools, rags, etc.

153.Parts and tools
Here is a list of parts and tools you will
need on performing doityourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
CHECKING THE ENGINE OIL LEVEL
Parts (if level is low):
Engine oil API grade SL “EnergyCon-
serving” or ILSAC multigrade having
viscosity proper for your climate
Tools:
Rag or paper towel
Funnel (only for adding oil)
CHECKING THE COOLANT LEVEL
Parts (if level is low):
”Toyota Genuine Long Life Coolant” or
equivalent
See page 217 in Section 82 for de-
tails about coolant type selection.
Demineralized or distilled water
Tools:
Funnel (only for adding coolant) CHECKING BRAKE FLUID

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 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.
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 f iller cap handtight.
Oil quantity, L (qt., Imp. qt.): 1.5 (1.6, 1.3)
NOTICE
Be careful not to spill the engine
oil on the vehicle components.
 Avoid overfilling, or the hybrid sys-
tem could be damaged.
 Check the oil level on the dipstick
once again after adding the oil.

Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SL. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W30. “Energy
Conserving” shown in the lower portion,
indicates that the oil has fuelsaving ca-
pabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.
To ensure excellent lubrication perfor-
mance for your engine, the “Toyota Genu-
ine Motor Oil” range is available, which
has been specifically tested and approved
for all Toyota engines.
Please contact your Toyota dealer for fur-
ther details of the “Toyota Genuine Motor
Oil” range.Look at the seethrough coolant reser-
voir when the hybrid system is cold.
The coolant level is satisfactory if it is
between the “FULL” and “LOW” lines
on the reservoir. If the level is low, add
ethyleneglycol type coolant for a prop-
er corrosion protection of aluminum
components.
The coolant level in the reservoir will vary
with hybrid system temperature. However,
if the level is on or below the “LOW” line,
add coolant. Bring the level up to the
“FULL” line.
Always use ethyleneglycol type coolant
for a proper corrosion protection of alumi-
num components. See information in the
next column.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
