The move comes after rival Mahindra and Mahindra Ltd increased prices of its personal and commercial vehicles by 1.9% this month due to higher commodity prices and input costs.
Indian automakers were already under pressure due to costs and weak demand when the pandemic dealt a blow last March.

Maruti's price hikes of up to 34,000 rupees ($464) will take effect from Monday, it said, without specifying the planned increases for individual models.
