Handling notes for coolant

handled with special care.
WARNING
_
• If coolant splashes in your eyes, thor-
oughly wash them with water and consult
a doctor.
• If coolant splashes on your clothes,
quickly wash it away with water and then
with soap and water.
• If coolant is swallowed, induce vomiting
and get immediate medical attention.
CAUTION:
_
• Adding water instead of coolant lowers
the antifreeze content of the coolant. If
water is used instead of coolant, check
and if necessary, correct the antifreeze
concentration 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

water.
