Vehicle specifications
Oil viscosity (5W-30 is explained here as an example): • The 5W in 5W-30 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 30 in 5W-30 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.
How to read oil container label:
The International Lubricant
Specification Advisory Commit-
tee (ILSAC) Certification Mark
is added to some oil containers
to help you select the oil you
should use.

Fuel information
■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.
■ Gasoline quality standards
●Automotive manufacturers in the U.S.A., Europe and Japan have developed
a specification for fuel quality called World-Wide Fuel Charter (WWFC),
which is expected to be applied worldwide.
● The WWFC consists of four categor ies that are based on required emission
levels. In the U.S., category 4 has been adopted.
● The WWFC improves air quality by lowering emissions in vehicle fleets, and
improves customer satisfaction through better performance.
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 s hould meet the specifications of
ASTM D4814 in the U.S.A.

4729-1. Specifications
■Recommendation of the use of gaso line 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,
please go to the official 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 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
●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.
●
Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).
DO NOT use gasoline
containing more than
15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)

4739-1. Specifications

Vehicle specifications
■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.
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.

WARNING
■
During customization
As the engine needs to be running during customization, ensure that the
vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may
collect and enter the vehicle. This may lead to death or a serious health
hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while cus-
tomizing features.

507What to do if... (Troubleshooting)
●Vehicles with a manual transmission:
Did you turn the key while firmly depressing the clutch pedal? (→P. 146)
●Vehicles with an automatic transmission:
Is the shift lever in P? (→P. 146)
●Is the battery discharged? ( →P. 450)
●Is the engine switch in the “ON” position?
If you cannot release the shift lever by depressing the brake pedal with the
engine switch in the “ON” position. ( →P. 151)
●It is locked to prevent theft of the vehicle if the key is pulled from the engine
switch. (→P. 147)
●Is the window lock switch pressed?
The power window except for the one at the driver’s seat cannot be oper-
ated if the window lock switch is pressed. ( →P. 122)
If you think something is wrong
The engine does not start
The shift lever cannot be shifted from P even if you depress
the brake pedal (vehicles with an automatic transmission)
The steering wheel cannot be turned after the engine is
stopped
The windows do not open or close by operating the power
window switches
