When trouble arises
■Stopping the engine
Shift the shift lever to P (automatic transmission) or N (manual transmission)
and press the engine switch as you normally do when stopping the engine.
■ 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. 599)
■ Alarm (vehicles with alarm for Kazakhstan, Armenia and Morocco)
Using the mechanical key to lock the doors will not set the alarm system.
If a door is unlocked using the mechanical key when the alarm system is set,
the alarm may be triggered.
■ Changing engine switch modes
Release the brake pedal (automatic transmission) or clutch pedal (manual
transmission) and press the engine switch in step above.
The engine does not start and modes will be changed each time the switch is
pressed. ( P. 288)
■ When the electronic key does not work properly
● Make sure that the smart entry & start system has not been deactivated in
the customization setting. If it is off, turn the function on.
(Customizable features: P. 718)
● Check if battery-saving mode is set. If it is set, cancel the function.
( P. 199)

HILUX_OM_OM0K321E_(EE)
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
Toyota retailer or Toyota authorized repairer, or any reliable repairer
as soon as possible.
■ Starting the engine when the battery is discharged (vehicles with auto-
matic transmission)
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.
(Vehicles with Stop & Start system: Except when the engine is stopped due
to 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.
■ When the battery is removed or discharged
● Information stored in the ECU is cleared. When the battery is depleted, have
the vehicle inspected at any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
● The power windows may not close normally. In this case, initialize the power
windows. (if equipped) ( P. 250)
■ 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
automatically during driving.)
■ When recharging or replacing the battery (vehicles with smart entry &
start system)
● 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 dis-
charged, be especially careful when reconnecting the battery.
● Vehicles with Stop & Start system: After the battery terminals have been dis-
connected and reconnected or, the battery has been replaced, the Stop &
Start system may not automatically stop the engine for approximately 5 to
60 minutes.
