Add coolant if necessary.

Water can be used in an emer-
gency if engine coolant is unavail-
able.

If water was added in an emer-
gency, have the vehicle inspected
at your Toyota dealer as soon as
possible.

Start the hybrid system and
turn the air conditioning sys-
tem on to check that the radi-
ator cooling fan operates and
to check for coolant leaks
from the radiator or hoses.

The fan operates when the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fan is operating by check-
ing the fan sound and air flow. If it is
difficult to check these, turn the air
conditioning system on and off

WARNING

■

When inspecting under the

hood of your vehicle

Observe the following precau-

tions.

Failure to do so may result in seri-

ous injury such as burns.

●

If steam is seen coming from

under the hood, do not open the

hood until the steam has sub-

sided. The engine compart-

ment may be very hot.

●

After the hybrid system has

been turned off, check that the

“READY” indicator is off.

When the hybrid system is oper-

ating, the gasoline engine may

automatically start, or the cool-

ing fan may suddenly operate

even if the gasoline engine

stops. Do not touch or approach

rotating parts such as the fan,

which may lead to fingers or

clothing (especially a tie, a scarf

or a muffler) getting caught,

resulting in serious injury.

●

Do not loosen the coolant reser-

voir cap while the hybrid system

and radiator are hot.

High temperature steam or

coolant could spray out.

NOTICE

■

When adding engine/power

control unit coolant

Add coolant slowly after the

hybrid system has cooled down

sufficiently. Adding cool coolant to

a hot hybrid system too quickly

can cause damage to the hybrid

system.

back and forth to free it, make

sure the surrounding area is clear

to avoid striking other vehicles,

objects or people. The vehicle

may also lunge forward or lunge

back suddenly as it becomes free.

Use extreme caution.

■

When shifting the shift posi-

tion

Be careful not to shift the shift

position with the accelerator pedal

depressed.
This may lead to unexpected

rapid acceleration of the vehicle

that may cause an accident

resulting in death or serious

injury.

NOTICE

■

To avoid damaging the trans-

mission and other compo-

nents

●

Avoid spinning the wheels and

depressing the accelerator

pedal more than necessary.

●

Engine oil selection

“Toyota Genuine Motor Oil” is
used in your Toyota vehicle.
Use Toyota approved “Toyota
Genuine Motor Oil” or equiva-
lent to satisfy the following
grade and viscosity.

Oil grade:

ILSAC GF-6B multigrade engine
oil

Recommended viscosity:

SAE 0W-16

SAE 0W-16 is the best choice
for good fuel economy and good
starting in cold weather.

If SAE 0W-16 is not available,
SAE 0W-20 oil may be used.
However, it must be replaced
with SAE 0W-16 at the next oil
change.

Outside temperature

Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 indicates

the characteristic of the oil
which allows cold startability.

Oils with a lower value before
the W allow for easier starting
of the engine in cold weather.

• The 16 in 0W-16 indicates the

viscosity characteristic of the
oil when the oil is at high tem-
perature. An oil with a higher
viscosity (one with a higher
value) may be better suited if
the vehicle is operated at high
speeds, or under extreme
load conditions.

How to read oil container label:

API registered mark is added to
some oil containers to help you
select the oil you should use.

Gasoline quality

In very few cases, driveability prob-
lems may be caused by the brand of
gasoline you are using. If driveability
problems persist, try changing the
brand of gasoline. If this does not
correct the problem, consult your
Toyota dealer.

■

Recommendation of the use of
gasoline containing detergent
additives

●

Toyota recommends the use of
gasoline that contains detergent
additives to avoid the build-up of
engine deposits.

●

All gasoline sold in the U.S.A. con-
tains minimum detergent additives
to clean and/or keep clean intake
systems, per EPA’s lowest addi-
tives concentration program.

●

Toyota strongly recommends the
use of Top Tier Detergent Gaso-
line. For more information on Top
Tier Detergent Gasoline and a list
of marketers, please go to the offi-
cial website www.toptiergas.com.

■

Recommendation of the use of
low emissions gasoline

Gasolines containing oxygenates
such as ethers and ethanol, as well
as reformulated gasolines, are avail-
able in some cities. These fuels are
typically acceptable for use, provid-
ing they meet other fuel require-
ments.

Toyota recommends these fuels,
since the formulations allow for
reduced vehicle emissions.

■

Non-recommendation of the
use of blended gasoline

●

Use only gasoline containing up to
15% ethanol.
DO NOT use any flex-fuel or gas-
oline that could contain more than
15% ethanol, including from any
pump labeled E30 (30% ethanol

), E50 (50% ethanol

), E85

(85% ethanol

) (which are only

some examples of fuel containing
more than 15% ethanol).

●

If you use gasohol in your vehicle,
be sure that it has an octane rat-
ing no lower than 87.

●

Toyota does not recommend the
use of gasoline containing metha-
nol.

■

Non-recommendation of the
use of gasoline containing MMT

Some gasoline contains an octane
enhancing additive called MMT
(Methylcyclopentadienyl Manga-
nese Tricarbonyl).

Toyota does not recommend the
use of gasoline that contains MMT.

Fuel information

You must only use unleaded
gasoline in your vehicle.

Select octane rating 87
(Research Octane Number
91) or higher. Use of
unleaded gasoline with an
octane rating lower than 87
may result in engine knock-
ing. Persistent knocking
can lead to engine damage.

At minimum, the gasoline you
use should meet the specifica-
tions of ASTM D4814 in the
U.S.A..

529

8-1. Specifications

Vehicle

specifications

If fuel containing MMT is used, your

emission control system may be

adversely affected.
The malfunction indicator lamp on

the instrument cluster may come on.

If this happens, contact your Toyota

dealer for service.

■

If your engine knocks

●

Consult your Toyota dealer.

●

You may occasionally notice light

knocking for a short time while

accelerating or driving uphill. This

is normal and there is no need for

concern.

NOTICE

■

Notice on fuel quality

●

Do not use improper fuels. If

improper fuels are used, the

engine will be damaged.

●

Do not use leaded gasoline.

Leaded gasoline can cause

damage to your vehicle’s three-

way catalytic converters caus-

ing the emission control system

to malfunction.

●

Do not use gasohol other than

the type previously stated.

Other gasohol may cause fuel

system damage or vehicle per-

formance problems.

●

Using unleaded gasoline with

an octane number or rating

lower than the level previously

stated will cause persistent

heavy knocking.

At worst, this will lead to engine

damage.

■

Fuel-related poor driveability

If poor driveability (poor hot start-

ing, vaporization, engine knock-

ing, etc.) is encountered after

using a different type of fuel, dis-

continue the use of that type of

fuel.

■

When refueling with gasohol

Take care not to spill gasohol. It

can damage your vehicle’s paint.

of Toyota vehicles with informa-
tion on uniform tire quality grad-
ing.

Your Toyota dealer will help answer
any questions you may have as you

■

DOT quality grades

All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades. Quality grades
can be found where applicable

on the tire sidewall between
tread shoulder and maximum
section width.

For example: Treadwear 200 Trac-
tion AA Temperature A

■

Treadwear

The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course.

For example, a tire graded 150
would wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.

The relative performance of tires
depends upon the actual conditions
of their use. Performance may dif-
fer significantly from the norm due
to variations in driving habits, ser-
vice practices and differences in
road characteristics and climate.

■

Traction AA, A, B, C

The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.

A tire marked C may have poor
traction performance.

Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.

Uniform Tire Quality
Grading

534

8-1. Specifications

■

Temperature A, B, C

The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.

Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.

Grade C corresponds to a level of

performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.

Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.

Warning: The temperature grades
of a tire assume that it is properly
inflated and not overloaded.

Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
