When trouble arises
GS350/250_EE (OM30C36E)One of the following may be the cause of the problem:
One or both of the battery terminals may be disconnected.
The battery may be discharged. (P. 825)
There may be a malfunction in the steering lock system.
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional if the problem cannot be repaired, or if repair
procedures are unknown.
When the engine does not start, the following steps can be used as
an interim measure to start the engine if the engine switch is func-
tioning normally:
Set the parking brake.
Shift the shift lever to P.
Turn the engine switch to ACCESSORY mode.
Press and hold the engine switch for about 15 seconds while
depressing the brake pedal firmly.
Even if the engine can be started using the above steps, the system
may be malfunctioning. Have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and
equipped professional.
The starter motor does not turn over, the interior lights and
headlights do not turn on, or the horn does not sound.

When trouble arises
GS350/250_EE (OM30C36E)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.
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 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.)
When recharging or replacing the battery
For vehicles with an alarm: make sure the key is not inside the vehicle when
recharging or replacing the battery to prevent the doors from being locked
with the key left inside the vehicle when the alarm operates.
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.
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
reconnected, 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.
