Nissan ARIYA 2023 Owners Manual
12.5.1. Checking coolant level
Check the coolant level in the reservoir when the high voltage parts are cold. If the coolant level is below the MIN level (2), open the reservoir cap and add coolant up to the MAX level (1). If the reservoir is empty, check the coolant level in the coolant tank when the high voltage parts are cold. If there is insufficient coolant in the coolant tank, fill the coolant tank with coolant up to the reservoir cap opening and also add it to the reservoir up to the MAX level (1).
Tighten the cap securely after adding coolant.
If the cooling system frequently requires coolant, have it checked by a NISSAN certified electric vehicle dealer.
