n t

ris

Open and close any of the door 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

in the exact reverse order from
which they were connected.

Once the engine starts, have the vehi-
cle inspected at your Lexus dealer as
soon as possible.

■

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 off.

●

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.

■

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 recharging or replacing the bat-

tery

●

In some cases, it may not be possible to

unlock the doors using the smart access

system with push-button start 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 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.

WARNING

■

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.

●

Do not allow the other end of the

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.

Engine oil selection

“Toyota Genuine Motor Oil” is used in
your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil”
or equivalent to satisfy 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.

Outside temperature

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-

cosity 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 con-
ditions.

How to read oil container label:
The International Lubricant Specifica-
tion Advisory Committee (ILSAC)
Certification Mark is added to some oil
containers to help you select the oil you
should use.
