The two plants put together roll out some 5,000 units of vehicles a day. The company temporarily halted production at the two plants on Saturday due to Jat agitation in Haryana.
Company sources said that it remains uncertain if production would resume at the factories even tomorrow.
Asked when the operations could resume at the two plants, a company spokesperson told PTI: "We will assess the situation in the morning and then decide the next course of action."
The protesters continued to block some roads including the arterial Delhi-Ambala Highway, demanding a written assurance that the community will be given reservation in the state.
The Jats also continued to block some roads including in Rohtak, Hisar and Bhiwani districts.
Road traffic on various national and state highways from Hissar to various destinations, including Delhi, Chandigarh, Sirsa, Siwani and Bhiwani remained suspended.
