The model contains two dilatonic coupling vectors obeying certain restrictions. It is shown that there exists a time interval where accelerating expansion of ``our'' 3-dimensional space is compatible with a small value of effective gravitational ``constant'' variation.4 pages, Latex, prepared for Proc. of the Russian summer school-seminar Modern theoretical problems of gravitation and cosmology, September 9-16, 2007, TSHPU, Kazan-Yalchik, RussiaGeneral Relativity and Quantum CosmologyAstrophysicstext
