How to Add Coolant to the
CAC Bottle
{
Warning
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. Do not spill
coolant on a hot engine.
Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
The CAC bottle pressure cap can
be removed when the Charged Air
Coolant cooling system, including
the CAC bottle pressure cap, is no
longer hot.
1. Turn the pressure cap slowly
counterclockwise and
remove it.
2. Fill the CAC bottle with the
proper mixture to the COLD
FILL mark pointed to on the
front of the CAC bottle.
3. Replace the pressure cap
tightly.
Engine Overheating
The vehicle has an engine coolant
temperature gauge and an engine
temperature light to warn of engine
overheating.
There are also engine hot
messages that may be displayed in
the Driver Information Center (DIC).

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, the fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
