3. Lift the hood and pull the prop
rod by the sleeve from the
retainer, located above the
radiator.
4. Securely place the hood prop
rod into the slot on the
underside of the hood.
To close the hood:
1. Before closing the hood, be
sure all the filler caps are on
properly. Then, lift the hood to
relieve pressure on the hood
prop rod. Remove the hood
prop rod by the sleeve from the
retainer slot on the underside
of the hood and return the
hood prop rod to its retainer
above the radiator. The hood
prop rod must click into place
when returning it to the retainer
to prevent hood damage.
2. Lower the hood 20 cm (8 in)
above the vehicle and release
it so it fully latches. Check to
make sure the hood is closed
and repeat the process if
necessary.

{Warning
An underhood electric fan can
start up even when the engine is
not running and can cause injury.
Keep hands, clothing, and tools
away from any underhood
electric fan.
{Warning
Do not touch heater or radiator
hoses, or other engine parts.
They can be very hot and can
burn you. Do not run the engine if
there is a leak; all coolant could
leak out. That could cause an
engine fire and can burn you. Fix
any leak before driving the
vehicle.
Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL engine
coolant mixture. SeeRecommended
Fluids and Lubricants0338and
Maintenance Schedule0329.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
seeEngine Overheating0253.

1.8L L4 Hybrid Coolant
Surge Tank
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down.
If coolant is visible but the coolant
level is not 5-10 mm (0.2-0.4 in)
above the mid-point of the coolant
surge tank, add a 50/50 mixture of
clean, drinkable water and
DEX-COOL coolant.
Be sure the cooling system is cool
before this is done.If no coolant is visible in the coolant
surge tank, add coolant as follows:
How to Add Coolant to the
Coolant Surge Tank
{Warning
Spilling coolant on hot engine
parts can burn you. Coolant
contains ethylene glycol and it will
burn if the engine parts are hot
enough.
{Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but
there would not be an overheat
warning. The engine could catch
fire and you or others could be
burned.
{Warning
Steam and scalding liquids from a
hot cooling system are under
pressure. Turning the pressure
cap, even a little, can cause them
to come out at high speed and
you could be burned. Never turn
the cap when the cooling system,
including the pressure cap, is hot.
Wait for the cooling system and
pressure cap to cool.
Caution
Failure to follow the specific
coolant fill procedure could cause
the engine to overheat and could
cause system damage. If coolant
is not visible in the surge tank,
contact your dealer.
The coolant surge tank pressure
cap can be removed when the
cooling system, including the surge
tank pressure cap and upper
radiator hose, is no longer hot.

1. Turn the pressure cap slowly
counterclockwise. If a hiss is
heard, wait for that to stop.
A hiss means there is still
some pressure left.
2. Keep turning the cap and
remove it.

3. Fill the coolant surge tank with
the proper mixture to 5-10 mm
(0.2-0.4 in) above the mid-point
on the coolant surge tank.
4. With the coolant surge tank
cap off, start the engine and let
it run until the upper radiator
hose starts getting hot. Watch
out for the engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level reaches5-10 mm (0.2-0.4 in) above the
mid-point on the coolant
surge tank.
5. Replace the cap tightly.
6. Check the level in the surge
tank when the cooling system
has cooled down. If the coolant
is not at the proper level,
repeat Steps 1–6 and reinstall
the pressure cap. If the coolant
still is not at the proper level
when the system cools down
again, see your dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and engine
damage may occur. Be sure the
cap is properly and tightly
secured.
