WARNING (Continued)
Never turn the cap when the
cooling system, including the
coolant surge tank pressure cap,
is hot. Wait for the cooling system
and coolant surge tank pressure
cap to cool if you ever have to
turn the pressure cap.
If coolant is needed, add the proper
DEX-COOL coolant mixture directly
to the surge tank, but be sure the
cooling system is cool before this
is done.
1. When the cooling system, including the coolant surge tank
pressure cap and upper radiator
hose, is no longer hot, remove
the pressure cap.
Turn the pressure cap slowly
counterclockwise about
one-quarter turn and then stop.
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 withthe proper DEX-COOL coolant
mixture until the level inside
stabilizes at the FULL COLD
mark on the front of the
surge tank.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed.
This greatly reduces the chance of
circuit overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
