Fuel information
■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.
■ If your engine knocks
●Consult your Toyota dealer.
● 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.
The engine is designed to operate at maximum performance using
unleaded gasoline with an octane ra ting of 93 (98 RON) or higher. If
an octane rating of 93 (98 RON) fuel is not readily available in your
area, unleaded gasoline with an octane rating of 91 (95 RON) may be
used with no detriment to engine dur ability or driveability. However,
you may notice a slight decrease in maximum engine performance
and you may hear some knocking (pin ging) of an engine while using
an octane rating of 91 (95 RON) fuel.
If the octane rating is less than 91, damage to the engine may occur
and may void the vehicle warranty.

■
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.
■ Fuel octane rating
This octane rating is the average of the Research Octane and Motor Octane
numbers and is commonly referred to as the Anti Knock Index.
Using a gasoline with a lower octane rating can cause persistent and heavy
knocking, which can damage the engine. Do not be concerned if your vehi-
cle sometimes knocks lightly when you drive up a hill or when you acceler-
ate. Contact your Toyota dealer if you use a fuel with the specified octane
rating and your vehicle knocks heavily or persistently.
■ Gasoline for California-certified LEV
If your vehicle was certified to California’s low emission vehicle (LEV) stan-
dards as indicated on the underhood tune-up label, it is designed to optimize
engine and emission performance with gasoline that meets the clean burn-
ing low-sulfur California gasoline specifications. If you live in any other state
than California, your vehicle will operate on gasoline meeting Federal speci-
fications. Gasoline sold outside California is permitted to have higher sulfur
levels, which may affect the performance of your vehicle’s catalytic converter
and may produce a sulfur exhaust odor or smell. Toyota recommends that
you try a different brand of unleaded gasoline having lower sulfur to deter-
mine if the problem is fuel related before returning your vehicle to an autho-
rized dealer for service.

■Toyota recommends the use of g asoline containing detergent additives
● Toyota recommends the use of gasoline that contains detergent additives
to avoid 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 con-
centration 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.
■ 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.
■ 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 93.
● Toyota DOES NOT recommend the use of gasoline containing methanol.
●Use only gasoline containing a maxi-
mum of 10% ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 10% etha-
nol, including from any pump labeled
E15, E30, E50, E85 (which are only
some examples of fuel containing more
than 10% ethanol).DO NOT use gasoline
containing more than 10%
ethanol.
(15% ethanol)
(50% ethanol)
(85% ethanol)

■
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
■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 may cause persistent heavy knocking.
At worst, this may lead to engine damage and will void the vehicle war-
ranty.
■ 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.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.

Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the
strands which form the plies in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked
“RADIAL” is a bias-ply tire.
TUBELESS or TUBE TYPE
A tubeless tire does not have a tube
and air is directly filled in the
tire. A tube type tire has a tube inside the tire and the tube main-
tains the air pressure.
Load limit at maximum cold tire inflation pressure ( →P. 273)
Maximum cold tire in flation pressure ( →P. 364)
This means the pressure to which a tire may be inflated.
Summer tire or all season tire (→ P. 273)
An all season tire has “M+S” on the sidewall. A tire not marked
“M+S” is a summer tire.
“TEMPORARY USE ONLY” (→ P. 332)
A compact spare tire is identified by the phrase “TEMPORARY
USE ONLY” molded into its sidewall. This tire is designed for tem-
porary emergency use only.
