5-2. Steps to take in an emergency
The engine has cooled down sufficiently.
Low engine coolant temperature indicator comes on.
Check the engine coolant level.
Look for obvious coolant leaks
from the radiator, hoses and
under the vehicle.
Note that water draining from the air conditioning is normal if it has
been used.
Add engine coolant if required.
Water can be used in an emer-
gency if engine coolant is
unavailable. ( P. 342)
Have the vehicle checked at your nearest Toyota dealer as soon as
possible.
