Pakistan’s hot climate puts extra strain on the cooling system:

Increased evaporation of coolant leading to low levels.
Engine cooling system failure due to excess heat.
Battery and inverter stress: High temperatures affect the hybrid battery’s efficiency and the inverter’s performance.

Owners should ensure the cooling system is well-maintained, perform coolant flushes, and check for leaks. Parking in the shade and using sunshades can help manage cabin and engine temperatures.
