able.
6Start the engine and turn the
air conditioning system on to
check that the radiator cool-
ing fan operates and to check
for coolant leaks from the
radiator or hoses.
The fan operates when the air con-
ditioning system is turned on imme-
diately after a cold start. Confirm
that the fan is op erating by check-
ing 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 oper-
ate in freezing temperatures.)
7 If the fan is not operating:
Stop the engine immediately
and contact your Toyota
dealer.
If the fan is operating:
Have the vehicle inspected at
the nearest Toyota dealer.
WARNING
■When inspecting under the
hood of your vehicle
Observe the following precau-
tions. 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 sub-
sided. The engine compart-
ment may be very hot.
●Keep hands and clothing (espe-
cially a tie, a sca rf 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 coolant reser-
voir caps 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 suffi-
ciently. 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 precau-
tions:
●Avoid contaminating the coolant
with foreign matter (such as
sand or dust etc.).
●Do not use any coolant additive.

3688-1. Specifications
■Oil capacity (Drain and refill
[Reference
*])
*: The engine oil capacity is a refer-ence quantity to be used when
changing the engine oil. Warm up
and turn off the engine, wait more
than 5 minutes, and check the oil
level on the dipstick.
■Engine oil selection
“Toyota Genuine Motor Oil” is
used in your Toyota vehicle. Use
Toyota approved “Toyota Genu-
ine Motor Oil” or equivalent to
satisfy the following grade and
viscosity.
Oil grade: ILSAC GF-6B multi-
grade engine oil
Recommended viscosity: SAE
0W-16
Outside temperature
SAE 0W-16 is the best choice
for good fuel economy and good
starting in cold weather. If SAE 0W-16 is not available,
SAE 0W-20 oil may be used.
However, it must be replaced
with SAE 0W-16 at the next oil
change.
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 tem-
perature. 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 label:
API registered mark is added to
some oil containers to help you
select the oil you should use.
