(Reuters) - Tesla Inc TSLA.O said on Friday it has increased its borrowing capacity for a car lease program to $1.1 billion from $600 million.

The move comes as the electric car maker spends heavily to fix production bottlenecks of its new Model 3 sedan.

The company increased the borrowing capacity under certain warehouse agreements, the company said in a filing. (bit.ly/2yx2P58) A spokesman said it was related to Tesla's car lease program.

In August, Tesla said it would raise about $1.5 billion through its first-ever offering of junk bonds as it seeks fresh sources of cash to ramp up production of its new Model 3 sedan.
