When trouble arises
Ensure that the shift lever is in P and depress the brake pedal.
Touch the Lexus emblem side of the
electronic key to the engine switch.
If any of the doors is opened or closed
while the key is being touched to the
switch, an alarm will sound to indicate
that the start function cannot detect the
electronic key.
Press the engine switch within 10 seconds of the buzzer sounding, keeping the
brake pedal depressed.
In the event that the engine switch still cannot be operated, contact your Lexus
dealer.
â– Stopping the engine
Shift the shift lever to P and press the engine switch as you normally do when stopping
the engine.
â– Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the electronic
key battery be replaced immediately when the battery is depleted. ( →P. 4 9 2 )
â– Changing engine switch modes
Within 10 seconds of the buzzer sounding, release the brake pedal and press the engine
switch.
The engine does not start and modes will be changed each time the switch is pressed.

5627-2. Steps to take in an emergency
GX 460 _O M_ OM6 0F 6 8U _(U )
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 switch off.
Maintain the engine speed of the second vehicle and start the engine of your
vehicle by turning the engine switch to IGNITION ON mode.
Once your vehicle’s engine has started, remove the jumper cables in the exact
reverse order in which they were connected.
Once the engine starts, have the vehicle checked at your Lexus dealer as soon
as possible.
â– Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
â– To prevent battery discharge
â—ŹTurn off the headlights and the audio system while the engine is off.
â—ŹTurn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
â– Charging the battery
The electricity stored in the battery will disc harge 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.)
â– When recharging or replacing the battery
â—ŹIn some cases, it may not be possible to unlock the doors using the smart access system
with push-button start when the battery is discharged. Use the wireless remote control
or the mechanical key to lock or unlock the doors.
â—ŹThe 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.
â—ŹThe 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.
