Romain Grosjean says Haas' first goal is to get as much mileage as possible on their new F1 car, which he will be debut at Barcelona.
The Frenchman, who has swapped Lotus for Haas in the off-season, is scheduled to drive the car on the opening day of pre-season testing.
He will then alternate days with his team-mate Esteban Gutierrez, who is making a return to racing having spent last season filling the role of Ferrari's reserve driver.
While many are eagerly awaiting Haas' first run, Grosjean insists ensuring that the car is reliable will be the team's first priority.
He explained: "The first thing for the test is to get the car to run and to work well from there. Hopefully, we can get a lot of mileage.
"This is a new team, so we need to get everyone to work together, all the engineers, mechanics and the drivers.
"We need to get as much data and knowledge as we can.
"It's important to get the reliability sorted as early as possible because we don’t get much testing and we’re going straight to Melbourne."
Pre-season testing gets underway at the Circuit de Barcelona-Catalunya on February 22.
