5 Secret MBUX Mercedes Tricks That Will Change Your Driving Experience
The MBUX (Mercedes-Benz User eXperience) system represents the evolution of automotive infotainment, integrating artificial intelligence and advanced voice controls to transform every journey into a personalized and technologically cutting-edge experience. However, many Mercedes owners use only a fraction of this revolutionary system's potential.
If you own a Mercedes equipped with MBUX and want to maximize its functionality, these 5 secret tricks will allow you to discover hidden features and optimizations that will change how you interact with your car.
1. Permanent Integrated Speed Cameras in Navigation - The Most Requested Trick
One of the most annoying limitations of the standard MBUX system is the inability to constantly display speed cameras without having to set a specific destination. The solution exists and is incredibly effective: installing speed cameras integrated directly into the navigation system.
This upgrade allows you to have:
- Always-active speed camera alerts even without a destination set
- Complete and updated database of all fixed and mobile speed cameras
- Perfect integration with the original MBUX system
- Simple and fast installation without hardware modifications
Installation is much simpler than you think. You can get the complete speed camera system for MBUX directly from this link: Complete Speedcamera Autovelox Mercedes MBUX, with step-by-step guided procedures and technical support included.
This solution has become indispensable for thousands of drivers who want to travel safely and peacefully, always knowing where speed control points are located.
2. Direct Access to Phone Assistants (Siri/Google/Gemini)
Here's a trick that very few people know: by holding the voice command button on the steering wheel for a longer time, instead of activating "Hey Mercedes", you can directly activate your connected smartphone's voice assistant.
How it works:
- Short press = Activates "Hey Mercedes" (MBUX command)
- Long press (3-4 seconds) = Activates Siri, Google Assistant, or Gemini
This allows you to:
- Make calls by saying "Call [contact name]"
- Send messages without taking your hands off the steering wheel
- Control phone apps that MBUX doesn't manage
- Use cloud services from your personal assistant
- Access your playlists on Spotify, Apple Music, etc.
It's particularly useful when you want to leverage your personal assistant's intelligence while maintaining the car's connectivity, without having to say "Hey Mercedes" to then switch to phone commands.
3. Hidden Voice Shortcuts Beyond "Hey Mercedes"
In addition to standard commands, MBUX hides some voice shortcuts that can significantly speed up interaction with the system:
Little-known direct voice commands:
- "Eco mode" - immediately activates economical driving without menus
- "Automatic air conditioning" - automatically regulates the ideal temperature
- "Increase/decrease temperature by [X] degrees" - precise climate control
- "Open sunroof" - direct control of panoramic roof (if present)
- "Sport plus mode" - activates the most extreme performance mode
Trick for concatenated commands: You can give multiple commands in one sentence, for example: "Hey Mercedes, call Marco and activate comfort mode" - the system will execute both actions in sequence.
4. Hidden HOLD Function for Automatic Transmission
For those who own a Mercedes with automatic transmission, the HOLD function is a real game-changer for city driving, but many don't know how to activate it correctly:
How it works:
- When you're stopped at a traffic light, in traffic, or at a level crossing
- Press the brake pedal deeper for a few seconds
- The system will automatically keep the car stopped even when completely releasing the pedal
- By pressing the accelerator, the car will start normally
Advantages of the HOLD function:
- Reduces fatigue of the right foot in heavy traffic
- Greater comfort in frequent stop-and-go situations
- Prevents rolling of the car uphill without using the handbrake
- Automatic activation without having to press any button
This function is particularly useful in cities with heavy traffic or for those who frequently encounter highway queues. Once tried, it becomes indispensable for daily driving.
5. Residual Heat A/C: Comfort Even with Engine Off
One of the most underestimated and useful tricks, especially in winter or on scorching summer days: the climate control's residual heat function.

How it works:
- As soon as you turn off the vehicle, press the A/C climate control button
- The car will continue to emit heat (or cold air) for several minutes
- Takes advantage of the engine's residual heat without consuming fuel
- Perfect for maintaining the cabin at the ideal temperature during brief stops
When it's most useful:
- In winter: to avoid entering a freezing car after a stop
- In summer: to keep the cabin cool during a lunch break
- For passengers: who remain in the car during quick errands
- Energy saving: you use residual heat instead of restarting the car
This trick is particularly appreciated by those who make many brief stops during the day and don't want to waste fuel for climate comfort.
Conclusions: Transform Your Mercedes into a Technology Powerhouse
The MBUX system offers incredible possibilities that go far beyond standard use. By implementing these 5 secret tricks, you'll be able to:
✅ Travel safer with always-active speed cameras
✅ Get the best of both worlds (MBUX + smartphone assistant)
✅ Control the car faster with hidden voice shortcuts
✅ Drive more comfortably with automatic HOLD function
✅ Save energy by utilizing the climate control's residual heat
The most impactful trick remains the integration of permanent speed cameras, a function that significantly improves driving safety and peace of mind. If you want to implement this and other optimizations, remember that the complete MBUX speed camera solution is available with guided installation and technical support.
Make the most of your Mercedes technology: every hidden function discovered is a step towards a smarter, safer, and more personalized driving experience.
