The Swiss team has so far failed to sore this season, being the only team to not have any points.
Now Kaltenborn has said that the team needs to alter their approach if they are to end 2016 on a high.
"We need to take different approaches," Kaltenborn told Autosport.
"When it comes to strategy we have to try something different because if you follow the mainstream then we know it's going to be very difficult to be in a position to get the opportunity and get the points.
"So absolutely we have to think outside the box otherwise we remain in our comfort zone and then it's not going to get us anywhere.
