The Battery Disconnect Switch
The battery disconnect switch is located in the R/H side wall trim panel of
the boot. When actuated, power to all control modules is disconnected and
only ‘keep alive memory’ power is maintained. Thus the quiescent power
drain on the battery is greatly reduced.
To maintain the battery charge level, press the battery disconnect switch and
use the battery conditioner to charge the battery whenever the vehicle is to
be out of use for some days.
If the battery disconnect function is used in conjunction with the battery
conditioner, the vehicle may be stored for many months without additional
battery maintenance.
Caution: The vehicle security systems will be totally disabled when the battery
disconnect switch is used. The vehicle will be secured only by the mechanical door
locks. Ensure that the vehicle is stored in a secure location.
Caution: Close and lock the doors before disconnecting the battery. The door window
seals will be damaged if the door is closed or opened when the battery is disconnected.
