Vehicle Care

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.

If no coolant is visible in the surge tank, add
coolant.

1. 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 about one full turn. If a
hiss is heard, wait for that to stop.
A hiss means there is still some
pressure left.

2. Keep turning the pressure cap slowly,

and remove it.

3. Fill the coolant surge tank with the

proper mixture to the full cold mark.

4. With the coolant surge tank pressure cap

off, start the engine and let it run until
the engine coolant temperature gauge
indicates approximately 90 °C (195 °F).
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 indicated mark.

5. Replace the pressure cap tightly.
6. Verify coolant level after the engine is

shut off and the coolant is cold.
If necessary, repeat coolant fill procedure
Steps 1

6.

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.

Engine Overheating

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.

The vehicle has several indicators to warn of
engine overheating.

There is a coolant temperature gauge and a
engine coolant temperature warning light in
the vehicle's instrument cluster. See

Engine

Coolant Temperature Gauge

and

.

In addition, there are ENGINE OVERHEATED
STOP ENGINE, ENGINE OVERHEATED IDLE
ENGINE, and ENGINE POWER IS REDUCED
messages in the Driver Information
Center (DIC).

If the decision is made not to lift the hood
when this warning appears, get service help
right away.

If the decision is made to lift the hood,
make sure the vehicle is parked on a level
surface. See
