Engine oil selection

2.5 L 4-cylinder (A25A-FKS) engine “Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use Toyota-approved “Toyota Genuine Motor Oil” or equivalent 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.

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 Wallow 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 a high temperature. 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.

3.5 L V6 (2GR-FKS) engine

“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use Toyota-approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following grade and viscosity. Oil grade: ILSAC GF-6A multigrade engine oil Recommended viscosity: SAE 0W-20 SAE 0W-20 is the best choice for good fuel economy and good starting in cold weather. If SAE 0W-20 is not available, SAE 5W-20 oil may be used. However, it must be replaced with SAE 0W-20 at the next oil change.

Oil viscosity (0W-20 is explained here as an example)

• The 0W in 0W-20 indicates the characteristic of the oil which allows cold startability. Oils with a lower value before the Wallow for easier starting of the engine in cold weather.

Fuel information

You must only use unleaded gasoline. 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 knocking. Persistent knocking can lead to engine damage. At a minimum, the gasoline you use should meet the specifications of ASTM D4814 in the U.S.A.

Gasoline quality

In very few cases, driveability problems 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. contains minimum detergent additives to clean and/or keep clean intake systems, per EPA’s lowest additives concentration program.
• Toyota strongly recommends the use of Top Tier Detergent Gasoline. For more information on Top Tier Detergent Gasoline and a list of marketers, please go to the official website www.toptiergas.com.

Recommendation of the use of low emissions gasoline

Gasoline containing oxygenates such as ethers and ethanol, as well as reformulated gasoline, are available in some cities. These fuels are typically acceptable for use, providing they meet other fuel requirements.
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 gasoline that could contain more than 15% ethanol, including from any pump labeled E30, E50, E85 (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 rating no lower than 87.
• Toyota does not recommend the use of gasoline containing methanol.

Non-recommendation of the use of gasoline containing MMT

• Some gasoline contains an 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.

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

1. Notice on fuel quality
   1. Do not use improper fuels. If improper fuels are used, the engine will be damaged.
   2. Do not use leaded gasoline.
      1. Leaded gasoline can cause damage to your vehicle’s three-way catalytic converters causing the emission control system to malfunction.
   3. Do not use gasohol other than the type previously stated.
      1. Other gasohol may cause fuel system damage or vehicle performance problems.
   4. Using unleaded gasoline with an octane number or rating lower than the level previously stated will cause persistent heavy knocking.
      1. At worst, this will lead to engine damage.
2. Fuel-related poor driveability
   1. If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is encountered after using a different type of fuel, discontinue the use of that type of fuel.
3. When refueling with gasohol
   1. Take care not to spill gasohol. It can damage your vehicle’s paint.

    1. Plies are layers of rubber-coated parallel cords. Cords are the strands that form the plies in a tire.
11. “TEMPORARY USE ONLY”
    1. A compact spare tire is identified by the phrase “TEMPORARY USE ONLY” molded on its sidewall. This tire is designed for temporary emergency use only.

Typical DOT and Tire Identification Number (TIN)

Uniform Tire Quality Grading

This information has been prepared in accordance with regulations issued by the National Highway Traffic Safety Administration of the U.S. Department of Transportation. It provides the purchasers and/or prospective purchasers of Toyota vehicles with information on uniform tire quality grading.  Your Toyota dealer will help answer any questions you may have as you read this information.

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 Traction AA Temperature A

Treadwear

The treadwear grade is a comparative 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 differ significantly from the norm due to variations in driving habits, service practices, and differences in road characteristics and climate.

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 (turning) traction.

Temperature A, B, C

The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.

• A 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 that all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109.
• Grades B and A represent higher levels of performance on the laboratory 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 separately or in combination, can cause heat buildup and possible tire failure.
