■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
●Turn off any unnecessary electrical components when the vehicle is running at a
low speed for an extended period, such as in heavy traffic.
■When the battery is removed or discharged
●The power back door must be initialized. (if equipped) (→P. 6 3 3 )
●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. 1 2 5 )
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehi-
cle is not in use, due to natural discharge and the draining effects of certain
electrical appliances. If the vehicle is left for a long time, the battery may dis-
charge, and the engine may be unable to start. (The battery recharges automat-
ically during driving.)
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 any authorized
Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional as soon as possible.STEP6
