CAUTION:
• Adding water instead of coolant lowers the
antifreeze content of the coolant. If water is
used instead of coolant check, and if nec-
essary, correct the antifreeze concentra-
tion of the coolant.
• Use only distilled water. However, if dis-
tilled water is not available, soft water may
be used.
• If coolant comes into contact with painted
surfaces, immediately wash them with wa-
ter.
• Do not mix different types of antifreeze.
