Vehicle identification  
Vehicle identification number  
The vehicle identification number (VIN) is the legal identifier for  
your vehicle. This is the primary identification number for your  
Toyota. It is used in registering the ownership of your vehicle.  
This number is stamped on the  
top left of the instrument panel.  
This number is also on the Cer-  
tification Label.

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 sat-  
isfy the following grade and viscosity.  
Oil grade: API SN/RC multigrade engine oil  
Recommended viscosity: SAE 0W-16  
SAE 0W-16 is the best choice for  
good fuel economy and good start-  
ing 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 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.

8-1. Specifications  
Fuel inform at ion  
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 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 gaso-  
line 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 concen-  
tration program.  
Toyota strongly recommends the use of Top Tier Detergent Gasoline. For  
more information on Top Tier Detergent Gasoline and a list of marketers,

8-1. Specifications  
Recommendation of the use of low emissions gasoline  
Gasolines containing oxygenates such as ethers and ethanol, as well as  
reformulated gasolines, 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%  
DO NOT use gasoline contain-  
ing more than 15% ethanol.  
ethanol.  
DO NOT use any flex-fuel or gasoline  
that could contain more than 15% etha-  
(30% ethanol)  
(50% ethanol)  
nol, including from any pump labeled  
E30, E50, E85 (which are only some  
examples of fuel containing more than  
15% ethanol).  
(85% 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 accelerat-  
ing or driving uphill. This is normal and there is no need for concern.  
491  
8-1. Specifications  
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 causing 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 performance  
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 starting, vaporization, engine knocking, etc.) is  
encountered after using a different type of fuel, discontinue the use of that  
type of fuel.  
When refueling with gasohol  
Take care not to spill gasohol. It can damage your vehicle’s paint.

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 Require-  
ments 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 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 condi-  
tions 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.  
8
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.  
498  
8-1. Specifications  
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 dissi-  
pate heat when tested under controlled conditions on a specified  
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.  
Grade C corresponds to a level of performance which all passenger  
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 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  
failure.
