SECTION 3

Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
breakin. But following a few simple tips
for the first 1000 km (600 miles) can add
to the future economy and long life of
your vehicle:
Avoid fullthrottle acceleration when
starting and driving.
Avoid racing the hybrid engine.
Try to avoid hard stops during the first
300 km (200 miles).FUEL TYPE
Your vehicle must use only unleaded
gasoline.
To help prevent gas station mixups, your To-
yota has a smaller fuel tank opening.
The
special nozzle on pumps with unleaded fuel
will fit it, but the larger standard nozzle on
pumps with leaded gas will not.
At a minimum, the gasoline you use
should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its
effectiveness and the emission con-
trol system to function improperly.
Also, this can increase maintenance
costs.
OCTANE RATING
Select unleaded gasoline with an Oc-
tane Rating of 87 (Research Octane
Number 91) or higher. Use of unleaded fuel with an octane num-
ber or rating lower than stated above will
cause persistent heavy knocking. If se-
vere, this will lead to engine damage.
If your engine knocks ...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady speed on level roads, consult your
Toyota dealer.
However, occasionally, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is normal
and there is no need for concern.
GASOLINE CONTAINING DETERGENT
ADDITIVES
Toyota recommends the use of gasoline that
contains detergent additives to avoid build
up of engine deposits.
However, all gasoline sold in the U.S. con-
tains detergent additives
to keep clean and/or
clean intake systems.

106.FUEL TANK CAPACITY45 L (11.9 gal., 9.9 lmp. gal.)
The given fuel tank capacity is measured
on EPA/CARB ORVR testing condition
which is approved for nominal capacity
measurement condition.
The fuel tank capacity is decreased at low
ambient temperature. (decreased by about
5 L (1.3 gal., 1.1 lmp. gal.) at 10 C
(14 F).)
107.Fuel pump shutoff system
The fuel pump shutoff system stops sup-
plying fuel to the engine to minimize the
risk of fuel leakage when the engine stalls
or an airbag inflates upon collision. To
restart the hybrid system after the fuel
pump shutoff system activates, turn the
ignition switch to “ACC” or “LOCK” once
and start it.
CAUTION
Inspect the ground under the vehicle
before restarting the hybrid system. If
you find that liquid has leaked onto
the ground, the fuel system has been
damaged and it is in need of repair.
In this case, do not restart the hybrid
system.
If you plan to drive your Toyota in
another country...
First , comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel (unleaded and minimum octane
number).

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.
