GS350_250_OM_OM30E16E_(EE)
■Stopping the engine
Shift the shift lever to P and press the engine switch as you normally do when stop-
ping the engine.

As the above procedure is a temporary measure, it is recommended that the elec-
tronic key battery be replaced immediately when the battery is depleted. (→P. 4 8 9 )
■Alarm (if equipped)
Using the mechanical key to lock the doors will not set the alarm system.
If a door is unlocked using the mechanical key when the alarm system is set, the
alarm may be triggered.
■Changing engine switch modes
Release the brake pedal and press the engine switch in step above.
The engine does not start and modes will be changed each time the switch is
pressed.( →P. 2 3 8 )
■When the electronic key does not work properly
●Make sure that the smart entry & start system has not been deactivated in the cus-
tomization setting. If it is off, turn the function on.
(Customizable features: →P. 6 5 0 )
●Check if battery-saving mode is set. If it is set, cancel the function. ( →P. 1 3 3 )
CAUTION
■When using the mechanical key and operating the power windows and moon
roof
Operate the power window or moon roof after checking to make sure that there is
no possibility of any passenger having any of their body parts caught in the window

When trouble arises

■When recharging or replacing the battery
●For vehicles with an alarm: make sure that the key is not inside the vehicle when
recharging or replacing the battery. The key may be locked in the vehicle if the
alarm is activated. (→P. 88)
●In some cases, it may not be possible to unlock the doors using the smart entry &
start system 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 battery, 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.
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted from the battery:
●Make sure each jumper cable is connected 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 “+” terminal 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 bat-
tery.
