7-2. Steps to take in an emergency
6 Open and close any of the doors of
your vehicle with the engine switch
OFF.
7
Maintain the engine speed of the
second vehicle and start the engine
of your vehicle by turning the
engine switch to ON.
8
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 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, the air condition-
●
ing system, the audio system, etc. 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 the battery is removed or dis-
■
charged
● Information stored in the ECU is cleared.
When the battery is depleted, have the
vehicle inspected at your Lexus dealer.
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.
● The power back door must be initialized.
(P.109)
When replacing the battery
■
Use a battery that conforms to European
●
regulations.
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 (592A) or greater.
• If the sizes differ, the battery cannot be
properly secured.
• If an improper battery is used, battery
performance may decrease and the
engine may not be able to restart.
• 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 your Lexus dealer.
WARNING
■ When removing the battery termi-
nals
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.
