● There may not be sufficient fuel in the vehicle’s tank.  
Refuel the vehicle.

Try to restart the engine again following correct starting procedures. 
( P. 233, 236)

( P.  8 7 ) 
One of the following may be the cause of the problem: 
● The battery may be discharged. (P. 750) 
● The battery terminal connections may be loose or corroded. 
The engine starting system may be malfunctioning due to an electrical 
problem such as electronic key battery depletion or a blown fuse. 
However, an interim measure is available to start the engine.  
( P. 746)
If the engine will not start even though correct starting proce- 
dures are being followed ( P. 233, 236), consider each of the fol- 
lowing points:
The engine will not start even though the starter motor operates
normally.
The starter motor turns over slowly, the interior lights and head-
lights are dim, or the horn does not sound or sounds at a low 
volume.

Set the parking brake, shift the shift leve r to P (Multidrive) or N (manual trans- 
mission) and press the engine switch as you normally do when stopping the

electronic key battery be replaced immediately when the battery is depleted. 
( P. 652) 
■ Alarm (if equipped) 
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 (Multidrive) or clutch pedal (manual transmission) 
and press the engine switch in step   above.

■ When recharging or replacing the battery 
● Vehicles with a 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. 
● Vehicles with a smart entry & start system: 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. 
● Vehicles with a smart entry & start system: The engine switch mode is mem- 
orized by the vehicle. When the battery is reconnected, the system will 
return to the mode it was in before the battery was discharged. Before dis- 
connecting 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 a 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 automatically stop the 
engine for approximately 5 to 60 minutes. 
■ When exchanging the battery (vehicles with a 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 Toyota retailer or Toyota authorized repairer, 
or any reliable repairer for details.
