CHANGING A FUSE

Fuses

WARNING: Always replace a fuse

with one that has the specified amperage
rating. Using a fuse with a higher
amperage rating can cause severe wire
damage and could start a fire.

E217331

If electrical components in the vehicle are
not working, a fuse may have blown. Blown
fuses are identified by a broken wire within
the fuse. Check the appropriate fuses before
replacing any electrical components.

Make sure that nothing gets caught in
moving parts.

•

Do not work on a vehicle with the engine
running in an enclosed space, unless you
are sure you have enough ventilation.

•

Keep all open flames and other burning
material (such as cigarettes) away from
the battery and all fuel related parts.

Working with the Engine Off

1. Set the parking brake and shift the

transmission to park (P).

2. Switch off the engine.

3. Block the wheels.

Working with the Engine On

WARNING: To reduce the risk of

vehicle damage and personal burn injuries,
do not start your engine with the air
cleaner removed and do not remove it

closed.

UNDER HOOD OVERVIEW

WARNING: The inverter system

controller contains various high-voltage
components that can cause serious bodily
harm or death. The inverter system
controller is not serviceable and should
never be touched, probed, or tampered
with.

Note: Do not attempt to service any of the
high-voltage components or wiring. For
easier identification, the high-voltage wiring
insulation is color coated orange.

ENGINE OIL CHECK

Note: Check the level before starting the
engine.

Note: Make sure that the level is between
the MIN and the MAX marks.

1. Make sure that your vehicle is on level

ground.

2. Turn the engine off and wait 10 minutes

for the oil to drain into the oil pan.

3. Remove the dipstick and wipe it with a

clean, lint-free cloth. Reinstall the dipstick
and remove it again to check the oil level.

If the level is at the MIN mark, add oil
immediately.

Adding Engine Oil

Note: Do not remove the filler cap when the
engine is running.

Note: Do not add oil further than the MAX
mark. Oil levels above the MAX mark may
cause engine damage.

Maintenance

Only use oils certified for gasoline engines
by the American Petroleum Institute (API). 
An oil with this trademark symbol conforms
to the current engine and emission system
protection standards and fuel economy
requirements of the International Lubricants
Specification Advisory Committee (ILSAC).

1. Remove the filler cap.
2. Add engine oil that meets our

specifications.  See Capacities and
Specifications (page 359).

3. Replace the filler cap. Turn it until you

feel a strong resistance.

ENGINE COOLANT CHECK

WARNING: Do not remove the

coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.

305

Maintenance

WARNING: Do not put coolant in the

windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield.

WARNING: To reduce the risk of

personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system is
under pressure. Steam and hot liquid can
come out forcefully when you loosen the
cap slightly.

WARNING: Do not add coolant

further than the MAX mark.

Your vehicle has two separate cooling
systems. One for cooling the engine and a
separate system for cooling the inverter
system controller that is specific to the hybrid
operating system. The two systems operate
similarly, with the inverter system controller
cooling system generally operating at a lower
temperature and pressure.

When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information. See Scheduled Maintenance
(page 462).

Note: Make sure that the coolant level is
between the MIN and the MAX marks on
the coolant reservoir.

Note:  Coolant expands when it is hot.  The
level may extend beyond the MAX mark.

Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.

Adding Coolant

WARNING: Do not remove the

coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.

WARNING: Do not add engine

coolant when the engine is on or the
cooling system is hot. Failure to follow this
instruction could result in personal injury.

Note:  Automotive fluids are not
interchangeable.  Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
