The following is a detailed product introduction to the heating wiper system of Mercedes - Benz, covering its technical principles, functional features and application scenarios:
I. Overview of the Heating Wiper System
Mercedes - Benz's heating wiper system (usually called HEATTEC or integrated in the Winter Package) is designed specifically for extremely cold, icy and snowy weather. Through its heating function, it prevents the wiper blades from freezing to the windshield, ensuring cleaning performance in low - temperature environments.
II. Core Technical Details
1. Integrated Design of Heating Elements
• Heated Wiper Blades:
◦ Flexible heating wires (made of copper - nickel alloy) are built into the wiper blades, evenly distributed on the back of the rubber blade in the area directly contacting the glass.
◦ The operating temperature range is from - 40°C to 80°C. It can quickly heat up to 20 - 25°C (in about 3 - 5 minutes), melting frost and ice and maintaining the flexibility of the blade.
• Heated Nozzles (optional):
◦ The washer fluid nozzles are integrated with a heating function to prevent the water spray ports from freezing, ensuring the normal spraying of the washer fluid (containing antifreeze).
2. Intelligent Temperature Control System
• Automatic Start - Stop Logic:
◦ When the external temperature is ≤ 4°C, the system automatically activates the heating function; when the temperature is ≥ 10°C, it turns off to save energy.
◦ It can be manually forced to turn on/off through the in - car central control screen.
• Energy Management:
◦ The heating power is dynamically adjusted (up to 200W), giving priority to ensuring the temperature of the core contact area of the wiper blade to avoid overloading the battery.
3. Special Materials of Wiper Blades
• Rubber Formula:
◦ A low - temperature silica gel composite material (with a graphene coating) is used, which still maintains elasticity at - 40°C, reducing friction noise with the glass.
• Aerodynamic Structure:
◦ The wiper arm adopts a spoiler design to reduce wind resistance and the risk of lift during high - speed driving.
III. Functional Advantages
1. Efficient De - icing:
◦ The heating function can melt a 5 - mm - thick ice layer within 5 minutes in a - 20°C environment, avoiding damage to the glass and wipers caused by manual ice - scraping.
2. All - weather Cleaning:
◦ Heating prevents the washer fluid from freezing. Combined with high - pressure spraying (pressure ≥ 3.5 bar), it can efficiently remove snow - mud and salt stains.
3. Extended Lifespan:
◦ It reduces rubber hardening and cracking caused by low temperatures, increasing the lifespan of the wiper blade by approximately 30%.
IV. Applicable Vehicle Models and Optional Configurations
• Standard - equipped Vehicles:
◦ The winter packages of some high - end series (such as S - Class, GLS, EQS) include heated wipers.
• Optional Package:
◦ Other vehicles can obtain it by choosing the Cold Weather Package, with a price of approximately $500 - $1,200 (varying by region).
V. User Usage Recommendations
1. Maintenance Points:
◦ Regularly clean the heating area of the wiper blade to avoid dirt accumulation affecting heat conduction.
◦ Use special antifreeze windshield washer fluid (freezing point ≤ - 35°C) in winter to prevent nozzle blockage.
2. Precautions:
◦ After long - term parking, it is recommended to remotely start the heating function in advance (through the Mercedes me APP).
◦ Avoid forcibly using the wipers on a dry glass to prevent overheating of the heating wires.
