Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Service (U.S. and Canada) on
page 13‑8 orRoadside Service
(Mexico) on page 13‑10. To get
help and keep everyone in the
vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
Carbon Monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
(Continued)
WARNING (Continued)
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about
5 cm (2 in) on the side of
the vehicle that is away from
the wind to bring in fresh air.
.Fully open the air outlets
on or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside
the vehicle and set the fan
speed to the highest setting.
See Climate Control System
in the Index.(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (Carbon
Monoxide) gas to get inside.
CO could overcome you and kill
you. You cannot see it or smell it,
so you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.
Run the engine for short periods
only as needed to keep warm, but
be careful.

Cooling System
When it is safe to lift the hood:
3.0 L V6 Engine Shown,2.8 L V6 Engine Similar
A. Engine Cooling Fan (Out of View)
B. Engine Coolant Surge Tank and Pressure Cap
{WARNING
An electric engine cooling fan
under the hood 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.
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on
a level surface.
The coolant level should be
between the MIN and MAX lines.
If it is not, the vehicle may have
a leak at the radiator hoses, heater
hoses, radiator, water pump,
or somewhere else in the cooling
system.
{WARNING
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not 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.
If there seems to be no leak,
with the engine on, check to
see if the electric engine cooling
fan is running. If the engine is
overheating, the fan should be
running. If it is not, the vehicle
needs service. Turn off the engine.

2. Then keep turning the pressurecap slowly and remove it.
3. Fill the coolant surge tank with the proper DEX-COOL
coolant mixture to the indicated
level mark.
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 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
DEX-COOL
®coolant mixture
to the coolant surge tank until
the level reaches the indicated
level mark.
5. Then replace the pressure cap. Be sure the pressure cap is
hand-tight. Check the level in the coolant surge
tank when the cooling system has
cooled down. If the coolant is not
at the proper level, repeat Steps 1
through 3 and reinstall the pressure
cap. If the coolant still is not at the
proper level when the system cools
down again, see your dealer.
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
There is an engine coolant
temperature warning light on
the vehicle's instrument panel.
See
Engine Coolant Temperature
Gauge on page 5‑15.
If the decision is made not to lift the
hood when this warning appears,
but instead get service help right
away. See Roadside Service (U.S.
and Canada) on page 13‑8 or
Roadside Service (Mexico) on
page 13‑10. 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 fans are running. If the
engine is overheating, both fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice:
Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: If the engine catches
fire because of being driven
with no coolant, your vehicle can
be badly damaged. The costly
repairs would not be covered by
the vehicle warranty.
