When Recharging Or Replacing The Battery; Avoiding Battery Fires Or Explosions - Lexus GS350 Owner's Manual

When recharging or replacing the battery

■
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. 73)
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 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.
