Do not tow with sling-type
equipment or hcia/fog light damage
will occur. Use wheel-lift or car
carrier equipment (additional
ramping may be required for car
carrier equipment). Use safety
chains and wheel straps.
To help avoid damaging a vehicle
during a tow over rough surfaces,
install a towing dolly beneath the
wheels that would otherwise be on
the ground during the tow. This
will increase clearance between the wheel-lift equipment and the
underbody
of the towed vehicle.

When you decide it’s safe to
lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
An
electric fan under the hood
h can start up even when the
engine is not running and can
injure
you. Keep hands, clothing
and tools away from any
underhood electric fan.
If the coolant inside the coolant
recovery tank is boiling, don’t do
anything else
until it cools down.
The coolant level should be at or above
the
FULL COLD mark. If it isn’t, you
may have a leak
in the radiator hoses,
heater hoses, radiator, water pump or
somewhere else
in the cooling system.

very hot. Don’t touch them.
If you
do, you can be burned.
Don’t 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.
