Valtteri Bottas wants to avoid another one-year deal with Mercedes and firm up his Formula 1 future for "at least" the next two seasons.
The Finnish driver won three races in 2017 after Mercedes signed him from Williams on a one-year deal to replace Nico Rosberg.
He earned a contract extension for 2018 but he and team-mate Lewis Hamilton both need to negotiate new deals to remain with Mercedes.
Bottas told Autosport he was in "no rush" to secure his future and that talks had not started in earnest.
"I would like to stay with this team, hopefully for a long time," he said. "That is my target.
"As long as I keep performing like I've been performing this year so far, naturally it should be OK, all good."
Bottas joked that if Mercedes only offers him another one-year deal then "we need to talk", and reiterated he hopes to secure a multi-year agreement.
"I always kind of had one-year deals, so I would naturally like to know at least for the next two years what I'm going to do," he said.
The 28-year-old said he was not interested in receiving an offer from another team to gain leverage in discussions and said he had a good relationship with team boss Toto Wolff.
"We speak a lot," Bottas said. "We are very open always about my performance, about the car performance.
"We haven't yet talked anything about next year, we think it's still a bit early."
