Yes, in many modern vehicles, including some Mercedes-Benz models, the ACC heating function (steering wheel heating) can be activated remotely before starting the vehicle. This feature is typically controlled via the vehicle's remote control system or through a smartphone app like Mercedes me.

How the Remote Activation Works:

1. Mercedes me App:
   • Mercedes-Benz vehicles, including the G-Class, often support the Mercedes me app, which allows drivers to remotely start the vehicle or activate certain features before entering.
   • Through this app, you can activate the steering wheel heating, along with other comfort systems like seat heating, air conditioning, or pre-conditioning the cabin to a desired temperature. This ensures that when you enter the vehicle, it’s already at a comfortable temperature.
2. Remote Key or Smart Key:
   • Some models may also allow remote activation of the heating functions through the vehicle's key fob. This can be done by holding down certain buttons on the key fob for a period of time (typically around 3 seconds).
   • While this is more common for functions like remote start or seat heating, certain models may include the steering wheel heating as part of this remote functionality.
3. Pre-conditioning:
   • In cold weather, many vehicles have the pre-conditioning option, where the vehicle is warmed up remotely, and steering wheel heating is one of the features that can be activated. This allows the vehicle to be pre-warmed, and the steering wheel can be heated before the driver even enters the car.
   • Pre-conditioning often works in conjunction with remote start and helps ensure that the vehicle is comfortable as soon as you get in.

How It Helps in Cold Weather:

• Activating the steering wheel heating remotely allows the vehicle to warm the wheel in advance, which is particularly beneficial in cold climates. This ensures that when you enter the vehicle, the steering wheel is already at a comfortable temperature, enhancing the driving experience.
• This feature is useful for drivers who want to avoid the discomfort of having to wait for the steering wheel to warm up after starting the vehicle.

Limitations:

• ACC heating activation via remote may be limited to certain vehicle configurations or packages. It may not be available in all models or in all regions.
• The vehicle’s battery must have sufficient charge to allow remote activation, and the vehicle itself must be equipped with the required systems, such as remote start or climate pre-conditioning.

Conclusion:

Yes, in many Mercedes-Benz vehicles, including the W465 G-Class, the ACC heating function for the steering wheel can be activated remotely before starting the vehicle. This is typically done through the Mercedes me app or, in some cases, through the vehicle's remote key fob. This feature helps ensure that the vehicle’s steering wheel is warm and ready before the driver even enters, providing added comfort, especially in cold weather.
