To ensure the operational reliability of the vehicle, always check the coolant level of both coolant reservoirs.
Adding coolant:
1. Let the engine cool down.
2. Turn the lid of the coolant reservoir slightly counterclockwise
to allow any excess pressure to dissipate, then open it.
3. Open the coolant reservoir lid fully.
4. If the coolant is low, slowly add coolant up to the specified
level; do not overfill.
5. Close the lid.
6. Have the cause of the coolant loss eliminated as soon as possible.
