7-2. Steps to take in an emergency
5
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.
6
Open and close any of the door 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 IGNITION ON
mode.
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 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.
When replacing the battery
■
Use a battery that conforms to European
●
regulations.
Use a battery that tha 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 the 20 hour rate capacity is low, even if
the time period where the vehicle is not
used is a short time, battery may dis-
charge and the engine may not be able to
start.
For details, consult your Lexus dealer.
