COLD mark.
If it isn’t, you may have a leak in the radiator hoses,

the cooling system.
A CAUTION:
I
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine
fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling
fans are running. If the
engine is overheating, both
fans should be running. If
they aren’t.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD
mark, add a 50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
coolant at the coolant surge tank, but be sure the cooling
system, including the coolant surge tank pressure cap, is
cool before you do it. (See “Engine Coolant”
in the
Index for more information.)
A CAUTION:
I
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and
if‘ you turn the coolant surge
tank pressure cap -- even a little -- they can come
out at
high speed. Never turn the cap when the
cooling system, including the coolant surge
tank
pressure cap, is hot. Wait for the cooling system
and coolant surge
tank pressure cap to cool if you
ever have to
turn the pressure cap.

Downloaded from www.Manualslib.com manuals search engine Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a 50/50 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
You can be burned
if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn
if the engine parts are hot
enough. Don’t spill coolant on a hot engine.

when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose, is no
longer hot. Turn the pressure cap slowly about
one-quarter turn to the left and then stop.
If you hear a hiss, wait for that to stop.
A hiss means
there is still some pressure left.
2. Then keep turning the pressure cap slowly, and
remove it.
3. Then fill the coolant surge tank with the proper
mixture, up to the
FULL COLD mark.

Downloaded from www.Manualslib.com manuals search engine 4. With the coolant surge tank pressure cap off, start the
engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the engine
cooling fans.
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 reaches the
FULL COLD mark.
5. Then replace the pressure cap. Be sure the pressure
cap is tight.

‘ A Cr N:
Never fill a portable fuel container while it is in

If the LOW OIL LEVEL message on the Driver
Information Center comes on, it means you need to
check your engine oil level right away. For more
information, see “Driver Information Center” in the
Index. You should check your engine oil level regularly;
this is an added reminder.
It’s
a good idea to check your engine oil level every time
you get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick is
next to the coolant surge
tank. The dipstick handle is
a round, yellow loop.
Turn off the engine and give the oil a few minutes to
drain back into the oil pan. If you don’t, the oil dipstick
might not show the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or a
cloth, then push it back in all the way. Remove it again,
keeping the tip down.
When to Add Engine Oil
If the oil is at or below the ADD mark, you’ll need to
add at least one quart of oil. But you must use the right
kind. This part explains what kind of oil to use. For
crankcase capacity, see “Capacities and Specifications”
in the Index.
