Solid, stationary, unpainted metallic point away from the battery and any mov-
ing parts as shown in the illustration

Start the engine of the second vehi-
cle. Increase the engine speed
slightly and maintain at that level for
approximately 5 minutes to
recharge the battery of your vehi-
cle.

Open and close any of the doors of
your vehicle with the engine switch
off.

Maintain the engine speed of the
second vehicle and start the engine
of your vehicle by turning the
engine switch to IGNITION ON
mode.

Once the vehicle’s engine has
started, remove the jumper cables
in the exact reverse order from
which they were connected.

Once the engine starts, have the vehi-
cle inspected at any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer as soon as pos-
sible.

■

Starting the engine when the battery is

discharged

The engine cannot be started by push-start-

ing.

■

To prevent battery discharge

●

Turn off the headlights and the audio sys-

tem while the engine is stopped. (Vehi-

cles with a Stop & Start system: Except

when the engine is stopped by the Stop &

Start system.)

●

Turn off any unnecessary electrical com-

ponents when the vehicle is running at a

low speed for an extended period, such

as in heavy traffic.

When trouble

ises

■

When removing the battery terminals

When the battery terminals are removed,

the information stored in the ECU is

cleared. Before removing the battery termi-

nals, contact any authorized Lexus retailer

or Lexus authorized repairer, or any reliable

repairer as soon as possible.

■

Charging the battery

The electricity stored in the battery will dis-

charge gradually even when the vehicle is

not in use, due to natural 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 automatically during driving.)

■

When the battery is removed or dis-

charged

●

In some cases, it may not be possible to

unlock the doors using the smart entry &

start system when the battery is dis-

charged. 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 recon-

nected, the system will return to the

mode it was in before the battery was dis-

charged. Before disconnecting the bat-

tery, 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.

●

Vehicles with power back door: The

power back door must be initialized.

(



P.126)

●

Vehicles with a Stop & Start system: After

the battery terminals have been discon-

nected then reconnected or the battery

has been replaced, the Stop & Start sys-

tem may not automatically stop the

engine for approximately 5 to 60 min-

utes.

■

Replacing the battery

●

Vehicles with Stop & Start system: Use a

genuine battery specifically designed for

use with the Stop & Start system or a bat-

tery with equivalent specifications to a

genuine battery. If an unsupported bat-

tery is used, Stop & Start system func-

tions may be restricted to protect the

battery. Also, battery performance may

decrease and the engine may not be able

to restart. Contact any authorized Lexus

retailer or Lexus authorized repairer, or

any reliable repairer for details.

●

Use a battery with the same case size as

the previous battery and an equivalent

20 hour rate capacity (20HR) or greater.

• If the sizes differ, the battery cannot be

properly secured.

• 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 dis-

charge and the engine may not be able to

start.

●

For details, consult any authorized Lexus

retailer or Lexus authorized repairer, or

any reliable repairer.

WARNING

■

When removing the battery terminals

Always remove the negative (-) terminal

first. If the positive (+) terminal contacts

any metal in the surrounding area when

the positive (+) terminal is removed, a

spark may occur, leading to a fire in addi-

tion to electrical shocks and death or

serious injury.

■

Avoiding battery fires or explosions

Observe the following precautions to

prevent accidentally igniting the flamma-

ble gas that may be emitted from the bat-

tery:

●

Make sure each jumper cable is con-

nected to the correct terminal and that

it is not unintentionally in contact with

any other than the intended terminal.

576

7-2. Steps to take in an emergency

WARNING

●

jumper cable connected to the “+” ter-

minal 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 cor-

rosive 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 battery 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 battery-related parts.

●

Do not allow children near the battery.

■

When replacing the battery

●

When the vent plug and indicator are

close to the hold down clamp, the bat-

tery fluid (sulfuric acid) may leak.

●

For information regarding battery

replacement, contact any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer.

Engine oil selection

“Toyota Genuine Motor Oil” is used in
your Lexus vehicle. Lexus recom-
mends the use of approved “Toyota
Genuine Motor Oil”. Another motor
oil of matching quality can also be
used.
Oil grade:
0W-20 and 5W-30
API grade SL “Energy-Conserving”,
SM “Energy-Conserving”, SN
“Resource-Conserving” or SN PLUS
“Resource-Conserving”; or ILSAC

multigrade engine oil
Recommended viscosity (SAE):

Temperature range anticipated
before next oil change
Preferred

SAE 0W-20 is filled into your Lexus
vehicle at manufacturing, and the best
choice for good fuel economy and
good starting in cold weather. If SAE
0W-20 oil is not available, SAE
5W-30 oil may be used. However, it
should 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 vis-
