If a large amount of coolant leaks,
immediately contact any authorized

6 Start the engine and turn the air
conditioning system on to check
that the radiator cooling fans

5628-2. Steps to take in an emergency
operate and to check for coolant
leaks from the radiator or hoses.
The fans operate when the air condi-
tioning system is tu rned on immediately after a cold start. Confirm that the fans
are operating by checking the fan
sound and air flow. If it is difficult to check these, turn the air conditioning
system on and off r epeatedly. (The fans
may not operate in freezing tempera- tures.)
7 If the fans are not operating:
Stop the engine immediately
and contact any authorized
Toyota retailer or Toyota author-
ized repairer, or any reliable
repairer.
If the fans are operating: Have
the vehicle inspected at the

■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 (espe-
cially a tie, a scarf or a muffler) away from the fans and belts. Fail-
ure to do so may cause the hands
or clothing to be caught, resulting in serious injury.
●Do not loosen the coolant reservoir 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 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 additive.

■Oil capacity (Drain and refill
[Reference*])
*: The engine oil capacity is a reference
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 dip-
stick.
■Engine oil selection
“Toyota Genuine Motor Oil” is used
in your Toyota vehicle. Toyota rec-
ommends the use of approved
“Toyota Genuine Motor Oil”.
Another motor oil of matching qual-
ity can also be used.
Oil grade:
0W-20 and 5W-30
API grade SM “Energy-Conserv-
ing”, SN “Resource-Conserving”,
SN PLUS “Resource-Conserving”
or SP “Resource-Conserving”; or
ILSAC GF-6A multigrade engine oil
Recommended viscosity (SAE):
Preferred
Temperature range anticipated
before next oil change
SAE 0W-20 is filled in to your Toyota
vehicle at manufacturing, and the
best choice for good fuel economy
and good starting in cold weather. If
SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used. How-
ever, it should be replaced with
SAE 0W-20 at the ne xt oil change.
Oil viscosity (0W-20 is explained
here as an example):
• The 0W in 0W-20 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 20 in 0W-20 indicates the
viscosity characteristic of the oil
when the oil is at high tempera-
ture. An oil with a higher viscos-
ity (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 containers to
help you select the oil you should
use.
