A vehicular heat management system is described and includes: a heater configured to carry out heating of a heat medium and stop the heating, and a heat exchanger configured to carry out heat exchange between lubricant oil for lubricating a speed change apparatus and the heat medium. A heat medium circulator is provided that is configured to switch the heat medium circulation state between a first circulation state where the heat medium circulates through the heater and the heat exchanger, and a second circulation state where the heat medium circulates through the heater and a heater core. An electronic control unit is also provided. When a pre-operation warm-up request to warm up the speed change apparatus and a pre-operation heating request to heat a vehicle cabin are both issued, the electronic control unit causes the heat medium circulator to switch the circulation state such that a warm-up of the speed change apparatus is carried out before heating of a vehicle cabin.
