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.
(Vehicles 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.
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 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
RC350-RC300_OM_General_OM24884E
7-2. Steps to take in an emergency
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 Stop & Start system:
●
For a while after the battery terminals
have been disconnected and recon-
nected, for a while after the battery has
been replaced, the Stop & Start system
may not automatically stop the engine for
approximately 5 to 60 minutes.
When replacing the battery (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
genuine battery. If an unsupported battery
is used, Stop & Start system functions may
be restricted to protect the battery.
Also, battery performance may decrease
and the engine may not be able to restart.
Contact your Lexus dealer for details.
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.
