Maintenance and care
SIENNA_U (OM45477U)
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. 664)
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. 664)
