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.

WARNING
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery:
● Make sure each jumper cable is connected to the correct terminal and that
it is not unintentionally in contact with any other than the intended terminal.
● Do not allow the other end of the jumper cable connected to the “+” termi-
nal to come into contact with any other parts or metal surfaces in the area,
such as brackets or unpainted metal.
● Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
● Do not smoke, use matches, cigarette lighters or allow open flame near
the battery.
■ Battery precautions
The battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery:
● When working with the battery, always wear safety glasses and take care
not to allow any battery fluids (acid) to come into contact with skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the battery support, terminals, and
other battery-related parts.
● Do not allow children near the battery.
■ To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
may overheat and become a fire hazard.

Engine oil selection
Gasoline Engine —
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota
recommends the use of approved “Toyota Genuine Motor Oil”.
Another motor oil of matching quality can also be used.
Oil grade:
0W-16:
API grade SN “Resource-Conserving” or SN PLUS “Resource-Con-
serving” multigrade engine oil
0W-20 and 5W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”, SN
“Resource-Conserving” or SN PLUS “Resource-Conserving”; or
ILSAC multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-16 is filled into your
Toyota vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-16 oil is not avail-
able, SAE 0W-20 oil may be
used. However, it should be
replaced with SAE 0W-16 at the
next oil change.
Temperature range anticipated
before next oil change

5149-1. Specifications
AYGO_OM_Europe_OM9A012E
Oil viscosity (0W-16 is explained here as an example):
• The 0W in 0W-16 indicates the characteristic of the oil which
allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.
• The 16 in 0W-16 indicates the viscosity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is
operated at high speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil contain-
ers to help you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designa-
tion by American Petroleum
Institute (API).
Center portion: “SAE 0W-16”
means the SAE viscosity grade.
Lower portion: “Resource-Con-
serving” means that the oil has
fuel-saving and environmental
protection capabilities.
ILSAC Certification Mark
The International Lubricant Specification Advisory Committee (ILSAC)
Certification Mark is displayed on the front of the container.
