If the engine coolant temperature gauge is
i
n
the overheat zone and an overheat DIC
message 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), and let the
engine idle.
If the engine coolant temperature gauge is no
longer in the overheat zone or an overheat DIC
message no longer displays, the vehicle can
be driven. Continue to drive the vehicle slowly
for about 10 minutes. Keep asafe distance
from the vehicle in front. If the engine coolant
temperature gauge does not go back to the
overheat zone or an overheat DIC message does
not display, continue to drive normally and
have the cooling system checked for proper fill
and function.
If the engine coolant temperature gauge is
still in the overheat zone or an overheat DIC
message still displays, pull over, stop, and park
the vehicle right away. If overheat messages
appear repeatedly, see your dealer.
If there is no sign of steam, idle the engine
fo
r three minutes while parked. If the engine
coolant temperature gauge is still in the
overheat zone or an overheat DIC message
displays, turn off the engine until it cools down.
Washer Fluid
What to Use
When windshield washer fluid is needed, be
sure to read the manufacturer's instructions
before use. If operating the vehicle in an
area where the temperature may fall below
freezing, use afluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap with the washer symbol on
it
. Add washer fluid until the tank is full.
See Engine Compartment Overview 3226 for
reservoir location.
Caution
•
Do
not use washer fluid that contains
any type of water repellent coating. This
can cause the wiper blades to chatter
or skip.
•
Do not use engine coolant (antifreeze)
in the windshield washer. It can
damage the windshield washer system
and paint.
•
Do not mix water with ready-to-use
washer fluid. Water can cause the
solution to freeze and damage the
washer fluid tank and other parts of
the washer system.
•
When using concentrated washer fluid,
follow the manufacturer instructions for
adding water.
•
Fill the washer fluid tank only three-
quarters full when it is very cold. This
allows for fluid expansion if freezing
occurs, which could damage the tank if it
is completely full.
