Nissan X-Trail 2024 Owners Manual
10.4. Checking engine coolant level
Check the coolant level in the reservoir when the engine is cold. If the coolant level is below the MIN level (2), open the reservoir cap and add coolant up to the MAX level (1).
Tighten the cap securely after adding engine coolant.
If the cooling system frequently requires coolant, have it checked. It is recommended you visit a NISSAN dealer or qualified workshop for this service.
