  1. Refill the cooling system. In order to ensure sufficient engine cooling, freezing and corrosion protection, maintain the protection level at-37°C (-34°F) or lower.
  2. Start the engine.
  3. Place the heater and A/C control in any A/C mode except Max and the temperature in the highest setting.
