7-2. Steps to take in an emergency

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

Maintain the engine speed of the second vehicle and start the

engine of your vehicle by turning the engine switch to IGNI-

TION ON mode.

Once the vehicle's engine has started, remove the jumper cables

in the exact reverse order from which they were connected.

Once the engine starts, have the vehicle inspected at any authorized

Lexus dealer or repairer, or another duly qualified and equipped

professional as soon as possible.

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.

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 cer-

tain electrical appliances. If the vehicle is left for a long time, the battery may

discharge, and the engine may be unable to start. (The battery recharges auto-

matically during driving.)

Vehicles with an alarm: 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. 90)

In some cases, it may not be possible to unlock the doors using the smart

entry & start system when the battery is discharged. Use the wireless

remote control or the mechanical key to lock or unlock the doors.
