■

Starting the engine when the battery is discharged

The engine cannot be started by push-starting.

■

To prevent battery discharge

●

Turn off the headlights and the audio system while the engine is off.

●

Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.

■

Charging the battery

The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)

■

When recharging or replacing the battery

●

In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless remote control
or the mechanical key to lock or unlock the doors.

●

The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.

●

The engine switch mode is memorized by the vehicle. When the battery is
reconnected, the system will return to the mode it was in before the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.

●

Make sure that the key is not inside the vehicle when recharging or replac-
ing the battery. The key may be locked in the vehicle if the alarm is acti-
vated. (

Engine oil selection

“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: 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 W allow
for easier starting of the engine in cold weather.

• The 20 in 0W-20 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.

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.

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 minimum, the gasoline you use should meet the specifications of
ASTM D4814 in the U.S.A..

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,
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.

■

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.

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.

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.

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.
