Maintenance and care
SIENNA_OM_OM45483U_(U)
CAUTION
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
■
When working on the engine compartment:
●Keep hands, clothing and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric c ooling fans or radiator grille
Vehicles without a smart key system: Be sure the engine switch is off. With
the engine switch in the “ON” position, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. ( P. 680)
Vehicles with a smart key system: Be sure the “ENGINE START STOP”
switch is off. With the “ENGINE START STOP” switch in IGNITION ON
mode, the electric cooling fans may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 680)

Engine oilWith the engine at operating temperature and turned off, check the oil
level on the dipstick.
■ Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than five minutes for the oil to
drain back into the bottom of the engine.
Holding a rag under the end, pull
the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully. Holding a rag under the end, pull
the dipstick out and check the oil
level.

Normal
Excessive
The shape of the dipstick may dif-
fer depending on the type of vehi-
cle or engine.
Wipe the dipstick and reinsert it fully.

*: 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 dipstick.
■ Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.

SIENNA_OM_OM45483U_(U)Oil viscosity (0W-20 is ex
plained 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 visc osity characteristic of the oil
when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be be tter suited if the vehicle is oper-
ated at high speeds, or under extreme load conditions.
How to read oil container label:
The International Lubricant Spec ification Advisory Committee
(ILSAC) Certification Mark is added to some oil containers to help
you select the oil you should use.
