YARIS_F_OM_Europe_OM52A54E
■Starting the engine when the battery is discharged (vehicles with a Multi-
drive)
The engine cannot be started by push-starting.
■ To prevent battery discharge
● Turn off the headlights and the audio system while the engine is stopped.
(Vehicles with a Stop & Start system: except when the engine is stopped by
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.
■ 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.)
■ 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.
● 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 Stop & Start system: For a while after the battery terminals
have been disconnected and 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 Stop & Start system)
Use a genuine battery specifically designed for use with the Stop & Start sys-
tem 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 retailers or
Toyota authorized repairers, or any reliable repairers for details.
■ 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, 20 hour rate
capacity (20HR) is equivalent or greater, and performance rating (CCA) is
equivalent or greater.
Check the label on top of the battery for the battery size and specifications
(ex. LN2, 60Ah, 520A).
• 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 retailers or Toyota authorized
repairers, or any reliable repairers.

Add coolant if necessary.
Water can be used in an emergency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fan operates and to check for coolant leaks
from the radiator or hoses.
The fan operates when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fan is operating by checking the fan
sound and air flow. If it is difficult to check these, turn the air conditioning
system on and off repeatedly.
(The fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the engine immediately and contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
