4907-2. Steps to take in an emergency
■Starting the engine when t he 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 .
■ When the battery is r emoved or discharged
● Information stored in the ECU is cleared. When the battery is d epleted, have
the vehicle inspected at your Toyota dealer.
● Some systems may require initialization. ( P. 533)
■ When removing the battery terminals
When the battery terminals are removed, the information stored in the ECU is
cleared. Before removing the battery terminals, contact your Toyota dealer.
■ 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 t ime, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When recharging or replacing the battery
●In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless rem ote 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 ba ttery is
reconnected, the system will return to the mode it was in befor e 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.
■ When replacing the battery
●Use a battery that conforms to European regulations.
● Use a battery that the case size is same as the previous one (L N3), 20 hour
rate capacity (20HR) is equivalent (70Ah) or greater, and perfo rmance rating
(CCA) is equivalent (603A) 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 w here the vehi-
cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
● For details, consult your Toyota dealer.

Votre véhicule est équipé de COUSSINS GONFLABLES INTELLI-
GENTS conçus selon les normes de sécurité américaines applicables
aux véhicules à moteur (FMVSS208). L'ensemble de capteurs de
coussins gonflables (E CU) régule le déploiement des coussins gon-
flables sur la base des informa tions qu'il reçoit des capteurs, etc., indi-
qués ci-dessus dans le schéma illu strant les composants du système.
Parmi ces informations figurent la gravité du choc et l'occupat ion du
véhicule par les passagers. Le d éploiement rapide des coussins gon-
flables est obtenu au moyen d'une réaction chimique dans les di sposi-
tifs pyrotechniques, qui produit un gaz inoffensif permettant d'amortir
le mouvement des occupants.
