{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.
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.
1. Remove the coolant surge tank pressurecap from the top chamber when the
cooling system, including the coolant
surge tank pressure cap and upper
radiator hose, is no longer hot. Turn the pressure cap slowly
counterclockwise. If you hear a hiss, wait
for that to stop. This will allow any
pressure still left to be vented out the
discharge hose.
2. Keep turning the pressure cap slowly and remove it. Open the surge tank service
port cap to the lower chamber.3. Fill the surge tank top chamber with theproper mixture to the bottom of the fill
neck. The top chamber needs to be
completely full. Fill the surge tank
bottom chamber through the service port
to approximately half. 4. With the coolant surge tank pressure cap
off and the surge tank service port cap
open, start the engine and let it run
until you can feel the upper radiator
hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the
coolant surge tank top chamber may be
lower. If the level is lower, add more of
the proper mixture to the surge tank top
chamber until the level reaches the
bottom of the fill neck.
5. Replace the surge tank pressure cap tightly and close the surge tank service
port cap.
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.
Check the level in the surge tank top and
bottom chambers when the cooling system
has cooled down. If the coolant is not at the
proper levels, repeat Steps 1–3 and reinstall
the pressure cap and close the service port.

252 Vehicle Care
If the coolant still is not at the proper levels
when the system cools down again, see
your dealer.
Engine Overheating
The vehicle has several indicators to warn of
the engine overheating.
There is an engine coolant temperature
gauge on the instrument cluster. SeeEngine
Coolant Temperature Gauge 088. The
vehicle may also display a message on the
Driver Information Center (DIC).
If the decision is made not to lift the hood
when this warning appears, get service help
right away. See Roadside Assistance Program
0 326.
If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface.
Then check to see if the engine cooling fan
is running. If the engine is overheating, the
fan should be running. If it is not, do not
continue to run the engine. Have the vehicle
serviced.
Caution
Do not run the engine if there is a leak
in the engine cooling system. This can
cause a loss of all coolant and can
damage the system and vehicle. Have
any leaks fixed right away.
If Steam Is Coming from the Engine
Compartment
{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.
If Steam Is Coming from the Engine
Compartment with no Overheat Warning
The hood extractor, if equipped, is
functional. It will allow water from rain and
car washes to enter the engine
compartment and contact hot surfaces. If steam is coming from the hood extractor
with no accompanying overheat warning, no
service is needed.
If No Steam Is Coming from the Engine
Compartment
If an engine overheat warning is displayed
but no steam can be seen or heard, the
problem may not be too serious. Sometimes
the engine can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day
.Stops after high-speed driving
.Idles for long periods in traffic
If the overheat warning is displayed with no
sign of steam: 1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) for
an automatic transmission or Neutral for
a manual transmission, and let the
engine idle.
If the engine coolant temperature gauge is
no longer in the overheated area, the
vehicle can be driven. Continue to drive the

the oil is changed. SeeEngine Oil Life
System 0244.
Engine Air Filter Change
When the REPLACE AT NEXT OIL CHANGE
message displays, the engine air filter
should be replaced at the next engine oil
change. When the REPLACE ENGINE AIR
FILTER SOON message displays, the engine
air filter should be replaced at the earliest
convenience. Reset the engine air filter life
system after the engine air filter is replaced.
See Engine Air Filter Life System (2.0L LTG
and 3.6L LGX Engines Only) 0246.
Air Conditioning Desiccant (Replace Every
Seven Years)
The air conditioning system requires
maintenance every seven years. This service
requires replacement of the desiccant to
help the longevity and efficient operation of
the air conditioning system. This service can
be complex. See your dealer.
Tire Rotation and Required Services
Every 12 000 km/7,500 mi
Rotate the tires, if recommended for the
vehicle, and perform the following services.
See Tire Rotation 0279.
.Check engine oil level and oil
life percentage. If needed, change engine
oil and filter, and reset oil life system.
See Engine Oil 0242 and
Engine Oil Life System 0244.
.If equipped with the engine air filter life
system, check the air filter
life percentage. If necessary, replace the
engine air filter and reset the engine air
filter life system. See Engine Air Filter Life
System (2.0L LTG and 3.6L LGX Engines
Only) 0246. If the vehicle is not
equipped with the engine air filter life
system, inspect the engine air cleaner
filter. See Engine Air Cleaner/Filter 0246.
