If you want to cancel timer you have to set it explicitely:

,----
| (setq my-timer (run-with-timer ....))

,----[ C-h f tooltip-show RET ]
| tooltip-show is a compiled Lisp function in `tooltip.el'.
| 
| (tooltip-show text &optional use-echo-area)
| 
| Show a tooltip window displaying text.
| 
| Text larger than `x-max-tooltip-size' is clipped.
| 
| If the alist in `tooltip-frame-parameters' includes `left' and `top'
| parameters, they determine the x and y position where the tooltip
| is displayed.  Otherwise, the tooltip pops at offsets specified by
| `tooltip-x-offset' and `tooltip-y-offset' from the current mouse
| position.
| 
| Optional second arg use-echo-area non-nil means to show tooltip
| in echo area.
