5-2. Steps to take in an emergency
ES350_U
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■Avoiding a discharged battery
●Turn off the headlights and the audio system while the engine is turned 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.
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 with the “ENGINE START
STOP” switch OFF.
Maintain the engine speed on the second vehicle and turn the
“ENGINE START STOP” switch to the IGNITION ON mode,
then start the vehicle’s engine.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at your Lexus dealer
as soon as possible.STEP3
