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 raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
●When using a floor jack, follow the instructions of the manual provided with
the jack.
● Do not use the jack that was supplied with your vehicle.
● Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
● Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
● Do not start the engine while the vehicle is supported by the floor jack.
● Stop the vehicle on level, firm ground, firmly set the parking brake and shift
the shift lever to P (vehicles with an automatic transmission) or R (vehicles
with a manual transmission).
● Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
