If the shift lever cannot be shifted with your foot on the brake
pedal, there may be a problem with the shift lock system (a sys-
tem to prevent accidental operation of the shift lever). Have the
vehicle inspected by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer immediately.
Also, when the vehicle’s battery is discharged, the shift lever
cannot be operated.

Connect a positive jumper cable clamp to the positive (+) battery
terminal on your vehicle.
Connect the clamp on the other end of the positive cable to the
positive (+) battery terminal on the second vehicle.
Connect a negative cable clamp to the negative (-) battery termi-
nal on the second vehicle.

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.
Vehicles with a smart entry & start system only: Open and close
any of the doors of your vehicle with the engine switch off.
Vehicles without a smart entry & start system:
Maintain the engine speed of the second vehicle and start the
engine of your vehicle.
Vehicles with a smart entry & start system:
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 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.
■ 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.
■ 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.)

5028-2. Steps to take in an emergency
AYGO_OM_Europe_OM9A012E
■ Precautions when the battery is discharged (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.
● 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.
■ When replacing the battery
● Use a battery that conforms to European regulations.
● Use a battery with the same case size as the previous one;
vehicles without cold area specifications or a stop & start system: (LN0),
20 hours rate capacity (20HR) is equiva lent (35Ah) or greater, and perfor-
mance rating (CCA) is equivalent (300A) or greater;
vehicles with cold area specifications: (LN0), 20 hours rate capacity (20HR)
is equivalent (42Ah) or greater, and performance rating (CCA) is equivalent
(390A) or greater; or
vehicles with a stop & start system: (LN2), 20 hours rate capacity (20HR) is
equivalent (60Ah) or greater, and performance rating (CCA) is equivalent
(540A) 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.
● For details, consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
