5-2. Steps to take in an emergency
When trouble arises
IS F_EE
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 run-
ning 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 bat-
tery 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 with the “ENGINE
START STOP” switch OFF.
Maintain the engine speed of the second vehicle and turn
the “ENGINE START STOP” switch to 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 any autho-
rized Lexus dealer or repairer, or another duly qualified and
id fil iblSTEP2
