The paper shows that any graph G with the maximum degree Δ( G ) ⩾ 8, which is embeddable in a surface Σ of Euler characteristic χ(Σ) ⩾ 0, is totally (Δ( G )+2)‐colorable. In general, it is shown that any graph G which is embeddable in a surface Σ and satisfies the maximum degree Δ( G ) ⩾ (20/9) (3−χ(Σ))+1 is totally (Δ( G )+2)‐colorable.
