The coolant level is satisfactory if it is between the “FULL” or “F”
and “LOW” lines on the reservoir.
Radiator cap
Reservoir
“FULL” or “F”
“LOW”
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fan operate and to check for coolant leaks
from the radiator or hoses.
The fan operate when the air conditioning system is turned on immediately
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 tem-
peratures.)

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 any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■ When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● If steam is seen coming from under the hood, do not open the hood until
the steam has subsided. The engine compartment may be very hot.
● Keep hands and clothing (especially a tie, a scarf or a muffler) away from
the fan and belts. Failure to do so may cause the hands or clothing to be
caught, resulting in serious injury.
● Do not loosen the radiator cap while the engine and radiator are hot. High
temperature steam or coolant could spray out.
NOTICE
■ When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding
cool coolant to a hot engine too quickly can cause damage to the engine.
■ To prevent damage to the cooling system
Observe the following precautions:
● Avoid contaminating the coolant with foreign matter (such as sand or dust,
etc.).
● Do not use any coolant additives.

If the vehicle becomes stuck
Stop the engine. Set the parking brake and shift the shift lever to N.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material to help provide traction
under the tires.
Restart the engine.
Shift the shift lever to E, M or R (multi-mode manual transmission)
or 1 or R (manual transmission) and release the parking brake.
Then, while exercising caution, depress the accelerator pedal.
■ When it is difficult to free the vehicle
Press to turn off TRC.
Turn off TRC and/or VSC if these functions are hampering your attempts to
free the vehicle. ( P. 280)
■ Emergency hooks
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt or snow:
When your vehicle becomes stuck and
cannot move, the emergency hooks are
used for another vehicle to pull your
vehicle to pull your vehicle out in an
emergency.
Your vehicle is not designed to tow
another vehicle.

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.

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.
