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
Hybrid model: Make sure that the indicator on the power switch and the
“READY” indicator are both off.
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 12-volt
battery. Fuel and 12-volt battery fumes are flammable.
Be extremely cautious when working on the 12-volt battery. It contains poi-
sonous and corrosive sulfuric acid.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system (except hybrid model):
Be sure the engine switch is off.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 507)
Vehicles with a smart entry & start system (except hybrid model):
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. (P. 507)
Hybrid model:
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 507)

Maintenance and care
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
Checking the engine oil
Gasoline engine: Park the vehicle on level ground. After turning
off the engine, wait more than 5 minutes for the oil to drain back
into the bottom of the engine.
Diesel engine: Park the vehicle on level ground. After warming
up the engine and turning it off, wait more than 5 minutes for the
oil to drain back into the bottom of the engine.
Hybrid model: Park the vehicle on level ground. After warming up
the engine and turning off the hybrid system, wait more than 5
minutes for the oil to drain back into the bottom of the engine.
Holding a rag under the end, pull the dipstick out.
