The rest ofthe bulletin:

...when vehicle is
a) stopped
b) in city "stop and go" traffic
c) when driving uphill
d) When driving at very high speed (with high engine load)

In individual cases the temperature may approach the red field of the temperature guage.

Provided the cooling system is well-maintained and in good working order, such temperature levels do not create any danger for teh engine and therefore give no cause for concern.

You now have seen everything in that technical bulletin. It was brief, but I an no typist...
