How to Remote Start Your Mercedes-Benz Using the Key Fob
Remote starting your Mercedes-Benz is a breeze with the key fob, particularly for models from 2015 onwards that are equipped with this feature. Follow these steps for a successful remote start:
1. Prepare Your Car for Remote Start
Before initiating the remote start, ensure that:
- Your vehicle is in Park (P) mode.
- All doors, including the hood and trunk, are securely closed.
- The key fob battery is functional.
Failure to meet these conditions will prevent the remote start from activating.
2. Lock Your Car First
Press the lock button on your key fob twice in quick succession. Listen for a beep and observe the parking lights flashing, which confirms that the vehicle is locked and ready for remote start.
3. Start the Engine Remotely
After locking the car, press and hold the remote start button (identified by a circular arrow) for 2-3 seconds. If successful, the parking lights will flash, and the engine will start within five seconds. Your Mercedes-Benz will run for 10 minutes before automatically shutting off unless you take control.
4. Enter the Vehicle Without Stalling It
To assume control:
- For push-start models (Keyless Go): Enter and press the start button once without stepping on the brake.
- For traditional key ignition models: Insert the key and turn it to the RUN position, allowing the engine to continue running.
5. Turn Off Remote Start (If Needed)
If you need to cancel the remote start for any reason, simply press the Panic button once, and the engine will shut off immediately.
Important Note: This feature might not be available on all Mercedes-Benz models. Always check your owner’s manual or consult your dealership to confirm if your vehicle supports remote start.
Why Remote Start is Essential for Your Mercedes
The convenience offered by keyless entry and remote start systems cannot be overstated. These innovations allow you to lock and unlock your car and start the engine without needing to fumble for a key. Common features include:
- Power door locks
- Delayed accessory power
- Enhanced cargo access
- Smart key proximity unlocking
- Climate control activation before entry
In extreme weather conditions, remote start proves invaluable. It warms the engine and fuel tank in cold climates and activates the air conditioning on hot summer days, ensuring a comfortable environment before you even enter the vehicle. Additionally, remote starting can facilitate roadside assistance; you can unlock your car, activate the power liftgate, or open doors remotely, making loading and unloading easier.
Common Issues and Challenges with Remote Starting a Mercedes-Benz
While remote start is a fantastic feature, many Mercedes-Benz owners have experienced issues, especially during winter months. Here are some common problems and how to address them:
1. Key Fob Not Responding
Problem: Some owners report that their key fob fails to activate the remote start function, only locking or unlocking doors.
Solution:
- Check the Battery: A weak or dead key fob battery is often the issue. Replace the battery and try again.
- Verify Compatibility: Confirm that your model has the remote start feature; older models or specific trims might not.
- Proximity to Vehicle: Ensure you are within range, as the signal may not reach if you’re too far away.
2. Vehicle Doesn’t Start After Multiple Attempts
Problem: Users may find that the car doesn’t start despite following the correct process.
Solution:
- Ensure Proper Mode: Make sure the vehicle is in Park and that all doors and the trunk are closed before attempting to start.
- Confirm with Dealership: If the issue persists, consult your dealership for potential electronic or system malfunctions.
3. Engine Shuts Off Too Quickly
Problem: The engine starts but shuts off shortly after, even when no one is inside.
Solution:
- Check for Faulty Sensors: Sensors may cause the vehicle to shut off if a door or hood isn’t closed properly.
- Modify Settings: Your dealership may be able to adjust settings to extend the remote start duration.
4. Cold Weather Issues
Problem: In extreme cold, the remote start may fail or the vehicle won’t start due to battery issues.
Solution:
- Ensure Battery Health: Cold temperatures can affect battery performance; check that your battery is strong enough.
- Use the Mercedes Me App: If available, this app may allow you to start your car remotely more effectively than the key fob.
Troubleshooting Remote Start Issues
If your car refuses to start remotely, your key fob may be indicating a problem. Count the parking light flashes to diagnose:
- 3 flashes: Normal shutdown
- 5 flashes: Too many remote starts (reset required)
- 6 flashes: Brake pedal was pressed
- 7 flashes: Hood is open
- 8 flashes: Engine RPM too high
- 9 flashes: Engine failed to start
- 10 flashes: Communication error
If remote start ceases to function, try this quick reset:
- Turn off the ignition.
- Lock the car with the key fob.
- Wait 5 minutes.
- Unlock the car.
- Start it manually with the key or push-start button.
- Allow it to run for a minute before turning it off.
