oil type TOYOTA PRIUS 2002 1.G Owners Manual

164
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 ethylene−glycol
type coolant for a proper corrosion
protection of aluminum components. Use
“TOYOTA Long Life Coolant” or equivalent.
See 210 page in Section 8 −2 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 8 −3 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 209 page in Section 8
−2 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 de −icer 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.
Winter driving tips

203
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.

Parts and tools
Here is a list of parts and tools you will
need on performing do−it−yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.

Parts (if level is low):
Engine oil API grade SJ “Energy −Con-
serving”, SL “Energy −Conserving” or IL-
SAC 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 Long Life Coolant” or equiva-
lent
See page 210 in Section 8 −2 for de-
tails about coolant type selection.

Low levelFull 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 out the dipstick, and wipe it clean with a rag.
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 on the end.
NOTICE
Make sure to hold a rag under the
dipstick, to avoid spilling drops of
engine oil when you pull it out.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
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.
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.): 1.5 (1.6, 1.3)
NOTICE
Be careful not to drop 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.
