7-2. Steps to take in an emergency
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.
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 battery recharges automatically during driving.)
When recharging or replacing the battery
■
In some cases, it may not be possible to unlock the doors using the smart access sys-
tem with push-button start when the battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
If the battery is discharged
■
The information stored in the computer will be deleted.
If the battery is discharged, have the vehicle inspected by your Lexus dealer.
