■

When the battery is removed or

discharged

●

Information stored in the ECU is

cleared. When the battery is

depleted, have the vehicle

inspected at your Toyota dealer.

●

Some systems may require initial-

ization. (



P.507)

■

When removing the battery ter-

minals

When the battery terminals are

removed, the information stored in

the ECU is cleared. Before remov-

ing the battery terminals, contact

your Toyota dealer.

■

Charging the battery

The electricity stored in the battery

will discharge gradually even when

the vehicle is not in use, due to nat-

ural discharge and the draining

effects of certain electrical appli-

ances. If the vehicle is left for a long

time, the battery may discharge,

and the engine may be unable to

start. (The battery recharges auto-

matically during driving.)

■

After jump starting the vehicle

(Vehicles with Stop & Start sys-

tem)

Be sure to disable the Stop & Start

system so that the battery can be

charged. (



P.265)

■

When recharging or replacing

the battery

●

In some cases, it may not be pos-

sible to unlock the doors using the

smart key system when the bat-

tery is discharged. Use the wire-

less 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 memo-

rized by the vehicle. When the

battery is reconnected, the system

will return to the mode it was in

before the battery was dis-

charged. Before disconnecting the

battery, turn the engine switch off.

If you are unsure what mode the

engine switch was in before the

battery discharged, be especially

careful when reconnecting the

battery.

●

Vehicles with power back door:

The power back door must be ini-

tialized. (



P.127)

●

Vehicles with Stop & Start system:

The Stop & Start system may not

automatically stop the engine for

up to an hour.

■

When replacing the battery

●

Use a Central Degassing type bat-

tery (European Regulations).

●

Vehicles with Stop & Start system:

Use a genuine battery specifically

designed for use with the Stop &

Start system or a battery with

equivalent specifications to a gen-

uine battery. If an unsupported

battery is used, Stop & Start sys-

tem functions may be restricted to

protect the battery.

Also, battery performance may

decrease and the engine may not

be able to restart. Contact your

Toyota dealer for details.

●

Vehicles without Stop & Start sys-

tem: Use a battery that the case

size is same as the previous one

(LN3), 20 hour rate capacity

(20HR) is equivalent (70Ah) or

greater, and performance rating

(CCA) is equivalent (603A) or

greater.

Vehicles with Stop & Start system:

Use a battery that the case size is

same as the previous one (LN3), 20

hour rate capacity (20HR) is equiva-

lent (65Ah) or greater, and perfor-

mance rating (CCA) is equivalent

(603A) or greater.

• If the sizes differ, the battery can-

not be properly secured.

468

7-2. Steps to take in an emergency

• If the 20 hour rate capacity is low,

even if the time period where the

vehicle is not used is a short time,

the battery may discharge and the

engine may not be able to start.

For details, consult your Toyota

dealer.

WARNING

■

When removing the battery

terminals

Always remove the negative (-)

terminal first. If the positive (+) ter-

minal contacts any metal in the

surrounding area when the posi-

tive (+) terminal is removed, a

spark may occur, leading to a fire

in addition to electrical shocks

and death or serious injury.

■

When disconnecting the bat-

tery

Do not disconnect the negative (-)

terminal on the body side. The

disconnected negative (-) terminal

may touch the positive (+) termi-

nal, which may cause a short and

result in death or serious injury.

■

Avoiding battery fires or

explosions

Observe the following precautions

to prevent accidentally igniting the

flammable gas that may be emit-

ted from the battery:

●

Make sure each jumper cable is

connected to the correct termi-

nal and that it is not unintention-

ally in contact with any other

than the intended terminal.

●

Do not allow the other end of

the jumper cable connected to

the “+” terminal to come into

contact with any other parts or

metal surfaces in the area, such

as brackets or unpainted metal.

●

Do not allow the + and - clamps

of the jumper cables to come

into contact with each other.

●

Do not smoke, use matches,

cigarette lighters or allow open

flame near the battery.

■

Battery precautions

The battery contains poisonous

and corrosive acidic electrolyte,

while related parts contain lead

and lead compounds. Observe

the following precautions when

handling the battery:

●

When working with the battery,

always wear safety glasses and

take care not to allow any bat-

tery fluids (acid) to come into

contact with skin, clothing or the

vehicle body.

●

Do not lean over the battery.

●

In the event that battery fluid

comes into contact with the skin

or eyes, immediately wash the

affected area with water and

seek medical attention. Place a

wet sponge or cloth over the

affected area until medical

attention can be received.

●

Always wash your hands after

handling the battery support,

terminals, and other bat-

tery-related parts.

●

Do not allow children near the

battery.

■

When replacing the battery

●

When the vent plug and indica-

tor are close to the hold down

clamp, the battery fluid (sulfuric

acid) may leak.

●

For information regarding bat-

tery replacement, contact your

Toyota dealer.

Engine oil selection

“Toyota Genuine Motor Oil” is
used in your Toyota vehicle. Use
Toyota approved “Toyota Genu-
ine Motor Oil” or equivalent to
satisfy the following grade and
viscosity.
Oil grade: ILSAC GF-6A multi-
grade engine oil
Recommended viscosity: SAE
0W-20

Outside temperature

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 tem-
perature. An oil with a higher
viscosity (one with a higher
value) may be better suited if

Gasoline quality

In very few cases, driveability prob-

lems 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. con-

tains minimum detergent additives

to clean and/or keep clean intake

systems, per EPA’s lowest addi-

tives concentration program.

●

Toyota strongly recommends the

use of Top Tier Detergent Gaso-

line. For more information on Top

Tier Detergent Gasoline and a list

of marketers, please go to the offi-

cial 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 avail-

able in some cities. These fuels are

typically acceptable for use, provid-

ing they meet other fuel require-

ments.
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 gas-

oline that could contain more than

15% ethanol, including from any

pump labeled E30 (30% ethanol
[

]), E50 (50% ethanol [

]), E85

(85% ethanol [

]) (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 rat-

ing no lower than 87.

●

Toyota does not recommend the

use of gasoline containing metha-

nol.

■

Non-recommendation of the

use of gasoline containing MMT

Some gasoline contains an octane

enhancing additive called MMT

(Methylcyclopentadienyl Manga-

nese Tricarbonyl).
Toyota does not recommend the use

of gasoline that contains MMT. If

fuel containing MMT is used, your

emission control system may be

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 knock-
ing. Persistent knocking
can lead to engine damage.

At minimum, the gasoline you
use should meet the specifica-
tions of ASTM D4814 in the
U.S.A.
