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 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 entry &
start system when the battery is dis-
charged. Use the wireless remote control
LEXUS NX300/NX200 Owners Manual̲General̲M78540̲en
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.
●
Some systems may require initialization.
●
Vehicle with Stop & Start system: After
the battery terminals have been discon-
nected and 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
Vehicle 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 gen-
uine battery.
If an unsupported battery is used, Stop &
Start system functions may be restricted to
protect the battery. Also, battery perfor-
mance 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.
