6-1. Specifications Fuel information

Your vehicle must use only unleaded gasoline. Unleaded gasoline with an Octane Rating 87 (Research Octane Num- ber 91) or higher required for optimum engine performance. At minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A. and CGSB3.5-M93 in Canada.

n Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your Toyota has a fuel tank opening that only accommodates the special nozzle on unleaded fuel pumps.

n If your engine knocks

l Consult your Toyota dealer. l You may occasionally notice light knocking for a short time while acceler-

ating or driving uphill. This is normal and there is no need for concern.

n Gasoline quality

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

n Gasoline quality standards

l Automotive manufacturers in the US, Europe and Japan have developed a specification for fuel quality called World-Wide Fuel Charter (WWFC) that is expected to be applied worldwide.

l The WWFC consists of four categories that are based on required emis-

sion levels. In the US, category 4 has been adopted.

l The WWFC improves air quality by lowering emissions in vehicle fleets,

and customer satisfaction through better performance.

n Toyota recommends the use of gasoline containing detergent additives l Toyota recommends the use of gasoline that contains detergent additives

to avoid build-up of engine deposits.

l All gasoline sold in the US contains detergent additives to clean and/or

keep clean intake systems.

PRIUS_U_(L/O_0802)

6-1. Specifications

n Toyota recommends the use of cleaner burning gasoline

Cleaner burning gasoline, including reformulated gasoline that contains oxy- genates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in many areas. Toyota recommends the use of cleaner burning gasoline and appropriately blended reformulated gasoline. These types of gasoline provide excellent vehicle performance, reduce vehicle emissions and improve air quality.

n Toyota does not recommend blended gasoline

l Toyota allows the use of oxygenate blended gasoline where the oxygen-

ate content is up to 10% ethanol or 15% MTBE. If you use gasohol in your Toyota, be sure that it has an octane rating no lower than 87.

l Toyota DOES NOT recommend the use of gasoline containing methanol.

n Toyota does not recommend gasoline containing MMT

Some gasoline contains octane enhancing additive called MMT (Methylcy clopentadienyl Manganese Tricarbonyl). Toyota DOES NOT recommend the use of gasoline that contains MMT. 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.

NOTICE

n Notice on gasoline quality

l Do not use leaded gasoline.

Leaded gasoline can cause damage to your vehicle’s three-way catalytic converters causing the emission control system to malfunction.

l Do not use gasohol other than that stated here.

Other gasohol may cause fuel system damage or vehicle performance problems.

l Using unleaded gasoline with an octane number or rating lower than that

stated here will cause persistent heavy knocking. At worst, this will lead to engine damage.

n Fuel-related poor driveability

If after using a different type of fuel, poor driveability is encountered (poor hot starting, vaporization, engine knocking, etc.), discontinue the use of that type of fuel.

n When refueling with gasohole

Take care not to spill gasohol. It can damage your vehicle’s paint.

PRIUS_U_(L/O_0802)

6-1. Specifications

n Treadwear

The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a speci- fied 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, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate.

n Traction AA, A, B, C

The traction grades, from highest 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 government 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 cornering (turn- ing) traction.

n Temperature A, B, C

The temperature grades are A (the highest), B, and C, represent- ing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a speci- fied indoor laboratory 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. The grade C corresponds to a level of performance which all passen- ger car tires must meet under the Federal Motor Vehicle Safety Stan- dard 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 for this tire are established for a tire that 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.
