WARNING
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 
● Make  sure  that  the  “ACCESSORY”  or  “IGNITION  ON”  on  the  multi-infor- 
mation display and the “READY” indicator are both off. 
● Keep hands, clothing and tools away from the moving fan. 
● Be  careful  not  to  touch  the  engine,  power  control  unit,  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 experi ence discom- 
fort, consult a doctor. 
■ When working near the electric cooling fans or radiator grille 
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 coo lant temperature 
is high. ( P. 606) 
■ Safety glasses 
Wear  safety  glasses  to  prevent  flying  or  falling  material,  flui d  spray,  etc., 
from getting in your eyes.

■Adding engine oil 
If the oil level is below or near the low level mark, add engin e oil of the 
same type as that already in the engine. 
Make  sure  to  check  the  oil  type  and  prepare  the  items  needed 
before adding oil. 
Remove the oil filler cap by turning it counterclockwise. 
Add engine oil slowly, checking the dipstick. 
Install the oil filler cap by turning it clockwise.
■ Engine oil consumption 
A certain amount of engine oil will be consumed while driving.  In the following 
situations,  oil  consumption  may  increase,  and  engine  oil  may  ne ed  to  be 
refilled in between oil maintenance intervals. 
● When the engine is new, for example directly after purchasing the vehicle or 
after replacing the engine 
● If low quality oil or oil of an inappropriate viscosity is used 
● When  driving  at  high  engine  speeds  or  with  a  heavy  load,  when  towing,  or 
when driving while accelerating or decelerating frequently 
● When  leaving  the  engine  idling  for  a  long  time,  or  when  driving  frequently 
through heavy traffic
