5-2. Steps to take in an emergency
nStarting the engine when the battery is discharged
The engine cannot be started by push-starting.
nTo prevent battery discharge
lTurn off the headlights and the audio system while the engine is off.

low speed for an extended period, such as in heavy traffic.

Connect a negative cable clamp to the negative (-) battery terminal
on the second vehicle
Connect the clamp at the other end of the negative cable to a solid,
stationary, unpainted metallic point away from the battery and any
moving parts, as shown in the illustration.
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.
