If it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center. If it is, you
may have a leak in the
radiator hoses, heater hoses, radiator, water pump or
somewhere else in the cooling system.
A CAUTION:
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, your vehicle needs service.

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.
1 NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
I A CAUTION:
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.
I. You can remove the coolant surge tank pressure
cap 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 until it first stops. (Don't press
down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.

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 about 2.5 inches (6.4 cm)
below the base of the filler neck.

the pressure cap
line up like this.
Start the engine and allow it to warm up. If the CHECK
COOLANT LEVEL message does not appear on the
Driver Information Center, coolant
is at the proper fill
level.
If a CHECK COOLANT LEVEL message does
appear, repeat Steps
1 through 3 or see your dealer.

1 CHECK OIL LEVEL message will appear when the
engine oil is approximately
1 quart (1 L) low. If the
message is displayed, check the dipstick level and add
oil
as needed.
It's a good idea to check your engine oil 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
located behind
the radiator
on the driver's side of the
engine. The black handle
says ENGINE OIL on it.
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.

Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove
it again,
keeping the tip down, and check the level.
When to Add Engine Oil
If the oil is at or below the ADD line, then 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.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.

The oil fill cap is located
behind the radiator
on the
passenger’s side
of the
engine.
Turn the cap to the
left to remove it.
Be sure to
fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you’re through.

The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.

The following explains your cooling system and
how
to add coolant when it is low. If you have a
problem with engine overheating, see “Engine
Overheating” in the Index.
A 50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you
use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or radiator corrosion may result. In addition, the
engine coolant will require change sooner

use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
