Additional Notes

  • The Lexus LBX 1.5 Hybrid carries two separate coolant circuits: the main cooling system and a dedicated inverter cooling system, each with its own capacity and change interval specifications.
  • The main cooling system holds 4.7-5 liters of coolant, while the inverter cooling system holds a noticeably smaller 1.6-1.7 liters, reflecting the more compact thermal management needs of the hybrid power electronics.
  • Both the front-wheel-drive and AWD variants share identical coolant capacities across both circuits, with 4.7-5 liters for the main system and 1.6-1.7 liters for the inverter system.
  • Under normal use conditions, both the main cooling system and the inverter cooling system are scheduled for a coolant change at 90,000 km intervals.
  • The first change only condition extends the main cooling system change interval significantly to 150,000 km, compared to the 90,000 km interval under normal use.
  • The inverter cooling system carries an especially extended first change only interval of 240,000 km, which is 150,000 km longer than the normal use change interval of 90,000 km for the same circuit.
  • Regardless of use condition or circuit type, the coolant check interval is set at 30,000 km across all configurations, keeping inspection frequency consistent while change intervals vary.
