When trouble arises

5-2. Steps to take in an emergency
GX460_OM_OM60J63U_(U)
■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, etc.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehicle
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 discharge, and the
engine may be unable to start. (The batt ery recharges automatically during driving.)
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately 5
minutes to recharge the battery of your vehicle.
Open and close any of the doors of your vehicle with the
“ENGINE START STOP” switch off.
Maintain the engine speed of the second vehicle and start the
engine of your vehicle by tu rning the “ENGINE START STOP”
switch to IGNITION ON mode.
Once your vehicle’s engine has started, remove the jumper
cables in the exact reverse ord er in which they were con-
nected.
Once the engine starts, have the ve hicle checked at your Lexus dealer
as soon as possible.STEP3
