"The forwards are the Boks strength so they need to play to that strength," said Jones, who helped South Africa achieve World Cup glory last October.
"Short attacks around the fringes would work well against the Welsh and then later the attacking backs can be brought into the game."
Jones believes the counter-attacking strengths of the Welsh pose a real threat to the Boks' chances of returning home undefeated.
"South Africa would be stupid to just throw the ball around in the British conditions, especially against Wales," Jones told South African Sunday newspaper Sondag.
"They could find things very difficult if they decide only to attack with the ball in hand. The Welsh enjoy living off other teams' mistakes and they will kill the Boks if the ball starts getting too loose."
