 P. 369 
■ Operation of the power switch 
● If the switch is not pressed shortly and firmly, the power switch mode may 
not change or the hybrid system may not start. 
● If attempting to restart the hybrid system immediately after turning the power 
switch off, the hybrid system may not start in some cases. After turning the 
power switch off, please wait a few seconds before restarting the hybrid sys-
tem.

WARNING
■When starting the hybrid system 
Always start the hybrid system while sitting in the driver’s seat. Do not 
depress the accelerator pedal while starting the hybrid system under any 
circumstances.
Doing so may cause an accident resulting in death or serious injury. 
■ Caution while driving 
If a hybrid system failure occurs while the vehicle is moving, do not lock or 
open the doors until the vehicle reaches a safe and complete stop. Activa- 
tion of the steering lock in this circumstance may lead to an accident, result-
ing in death or serious injury. 
■ Stopping the hybrid system in an emergency 
If you want to stop the hybrid system in an emergency while driving the 
vehicle, press and hold the power switch for more than 3 seconds, or press 
it briefly 3 times or more in succession. ( P. 395) 
However, do not touch the power switch while driving except in an emer- 
gency. Turning the hybrid system off while driving will not cause loss of 
steering or braking control, however,  power assist to the steering will be 
lost. This will make it more difficult to steer smoothly, so you should pull over
and stop the vehicle as soon as it is safe to do so.

YARIS_HV_OM_Europe_OM52G76E
Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicle 
body, wheel wells and underside of the vehicle to remove any dirt
and dust. 
● Wash the vehicle body using a sponge or soft cloth, such as a 
chamois. 
● For hard-to-remove marks, use car wash soap and rinse thoroughly 
with water. 
● Wipe away any water. 
● Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle 
body is cool.
■ Automatic car washes 
● Fold the mirrors and remove the antenna before washing the vehicle. Start 
washing from the front of the vehicle. Make sure to re-install the antenna 
and extend the mirrors before driving. 
● Brushes used in automatic car washes may scratch the vehicle surface and 
harm your vehicle’s paint. 
● Rear spoiler (if equipped) may not be washable in some automatic car 
washes. There may also be an increased risk of damage to vehicle. 
■ High pressure car washes 
● Do not allow the nozzles of the car wash to come within close proximity of 
the windows and door borders, and high mounted stoplight. 
● Before using the car wash, check that the fuel filler door on your vehicle is 
closed properly. 
■ When using a car wash (vehicles with a smart entry & start system 
equipped with entry function) 
If the door handle becomes wet while the electronic key is within the effective 
range, the door may lock and unlock repeatedly. Place the key in a position 
2 m (6 ft.) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)
Perform the following to protect the vehicle and maintain it in 
prime condition:

Maintenance and care

■Before recharging 
When recharging, the 12-volt battery produces hydrogen gas which is flam- 
mable and explosive. Therefore, obser ve the following precautions before 
recharging: 
● If recharging with the 12-volt battery installed on the vehicle, be sure to dis- 
connect the ground cable. 
● Make sure the power switch on the charger is off when connecting and dis- 
connecting the charger cables to the 12-volt battery. 
■ When disconnecting the 12-volt battery terminals 
Always disconnect the negative (-) terminal first. 
■ After recharging/reconnecting the 12-volt battery 
● Unlocking the doors using entry function of the smart entry & start system 
may not be possible immediately after reconnecting the 12-volt battery. If 
this happens, use the wireless remote control or the mechanical key to lock/
unlock the doors. 
● Vehicles with a smart entry & start system: Start the hybrid system with the 
power switch in ACCESSORY mode. The hybrid system may not start with
the power switch turned off. However, the hybrid system will operate nor- 
mally from the second attempt. 
● Vehicles with a smart entry & start system: The power switch mode is 
recorded by the vehicle. If the 12-volt battery is reconnected, the vehicle will 
return the power switch mode to the status it was in before the 12-volt bat- 
tery was disconnected. Make sure to turn off the power before disconnect
the 12-volt battery. Take extra care when connecting the 12-volt battery if 
the power switch mode prior to discharge is unknown. 
If the system will not start even after multiple attempts, contact any authorized 
Toyota dealer or repairer, or another  duly qualified and equipped professional.
