IS200t_EE(OM53D77E)
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
retailer or Lexus authorized repairer, or an y reliable repairer 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 stopped. (Vehicles with
a Stop & Start system: except when the engine is stopped by the Stop & Start system.)
●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 entry & start
system when the battery is discharged. Us e the wireless remote control or the mechan-
ical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged but will
start normally after the second attempt. This is not a malfunction.
●The engine switch mode is memorized by the vehicle. When the battery is recon-
nected, the system will return to the mode it was in before the battery was discharged.
Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery discharged, be
especially careful when reconnecting the battery.
●Vehicles with Stop & Start system:
For a while after the battery terminals have been disconnected or reconnected, for a
while after the battery has been replaced, the Stop & Start system may not automati-
cally stop the engine for approximately 5 to 60 minutes.
■When exchanging the battery (vehicles with Stop & Start system)
Use a battery specified for use with the Stop & Start system and equivalent to a genuine
battery. If an unsupported battery is used, Stop & Start system functions may be
restricted to protect the battery.
Also, battery performance may decrease and the engine may not be able to restart.
Contact any authorized Lexus retailers or Le xus authorized repairers, or any reliable
repairers.
