Cooling system
Check the coolant pot
Motor coolant expansion pot
PTC heater system coolant/battery
pack coolant pot
■
The coolant level in the expansion
pot should be between “MAX”
(highest scale level) and “MIN”
(lowest scale level) marking lines.
■
If the coolant level is below the lowest level, must add the coolant to the highest (MAX)
level. Check the cooling system for leakage.
■
The coolant should have the same specifications as the original coolant. Do not add
any mixture. Different brands and models of antifreezes cannot be mixed.
Tip
●
If opening the pot lid when the motor is not cooled completely, it may cause the
spilling of the coolant, resulting in severe burns.
Note
●
Do not add any rust inhibitor or other additive into the cooling system. Because the
additive may be incompatible with the coolant or the motor assembly.
●
Before opening the pot lid, must ensure that the motor, high-voltage electronic
control module, pot and the radiator are cooled completely.
