■
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the 12-volt battery
may discharge, and the engine may be unable to start. (The 12-volt battery
recharges automatically during driving.)
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain that level for approximately 5 min-
utes to recharge the battery of your vehicle.
Open and close any of the doors with the “ENGINE START
STOP” switch off.
Maintain the engine speed of the second vehicle and start the
engine of your vehicle by turning the “ENGINE START STOP”
switch to IGNITION ON mode.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order from which they were con-
nected.
Once the engine starts, have the vehicle inspected at your Lexus
dealer as soon as possible.
