When trouble arises
Fuel pump shut off system (gasoline engine only)
Follow the procedure below to restart the engine after the system is 
activated. 
Turn the engine switch to the “ACC” or “LOCK” position (vehicles 
without smart entry & start system) or ACCESSORY mode or off 
(vehicles with smart entry & start system). 
Restart the engine.
To minimize the risk of fuel leakage when the engine stalls or 
when an airbag inflates upon collision, the fuel pump shut off 
system stops the supply of fuel to the engine.
NOTICE
■ Before starting the engine 
Inspect the ground under the vehicle. 
If you find that fuel has leaked onto the ground, the fuel system has been 
damaged and is in need of repair. Do not restart the engine.

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

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.

When trouble arises
■When exchanging the battery 
● Use a battery that conforms to European regulations. 
● Use a battery with the same case size as the previous battery and an equiv- 
alent 20 hour rate capacity (20HR) or greater. 
• If the sizes differ, the battery cannot be properly secured. 
• If the 20 hour rate capacity is low, even if the time period where the vehi-
cle is not used is a short time, the battery may discharge and the engine 
may not be able to start. 
● Vehicles with Stop & Start system: Use a genuine battery specifically 
designed for use with the Stop & Start system or a battery with equivalent
specifications 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. 
● For details, consult any authorized Toyota retailer or Toyota authorized 
repairer, or any reliable repairer.
