Fernando Alonso claims tensions within the McLaren team have eased since he aired his grievances before the US GP.
Tensions had been building between Hamilton and Alonso
Spain's reigning F1 champion claimed McLaren were favouring homegrown talent Lewis Hamilton, but boss Ron Dennis insisted they were treated as equals.
Alonso told Spanish radio station Cadena Ser: "Since then, the team have taken more care in the details.
"They are showing more manners and in the last race, all the team showed a genuine happiness for both drivers."
Alonso trails rookie sensation Hamilton by 10 points in the title race, having seen him win the last two GPs, in the US and Canada.
But he is confident he can successfully defend his world title as the F1 season enters its run of European races.
"Now my world championship really begins," he said.
"France, Great Britain, Germany and Hungary are races that I like and that I have won at some point.
"I'm confident that things will once again go well for me. I feel more comfortable in the car and everything is going better.
"We are better than two weeks ago. We are showing a great reliability, the cars are fast and both drivers can fight for victory or the podium."
Alonso added he is not upset that McLaren share his telemetry data with Hamilton.
"He gets my data but I also get his data," he said. "However, the one that gets the car ready on a Friday is me."
