Summary

• eCall contacts emergency services automatically: After a serious crash.
• Mandatory since 2018: All new cars in the EU/UK must have it.
• Works anywhere in Europe: Connects to local emergency services.

eCall is a life-saving system built into modern cars. It can automatically call for help when you can't. Here's how it works.

What Is eCall?

eCall (emergency call) is an automatic emergency response system. When triggered, it:

1. Dials 112 (Europe's emergency number)
2. Sends your location to emergency services
3. Opens a voice channel so you can speak to operators
4. Sends vehicle data to help responders

It's designed to work when you can't call for help yourself – like after a serious crash.

How eCall Works

Automatic Activation

The system activates automatically when:

• Airbags deploy
• Crash sensors detect a severe impact
• Seatbelt pretensioners fire

What Happens Next

1. Call placed: eCall dials 112 within seconds
2. Data sent: Location, time, vehicle type, direction of travel
3. Voice channel opens: Operator can speak to occupants
4. Help dispatched: Emergency services sent to exact location

Manual Activation

You can also press the SOS button manually for any emergency – not just crashes.

What Data Is Sent?

The Minimum Set of Data (MSD) includes:

• Location: GPS coordinates
• Time: When the crash occurred
• Vehicle ID: VIN number
• Vehicle type: Car, van, etc.
• Fuel type: Petrol, diesel, electric, hybrid
• Direction of travel: Helps find you on motorways
• Number of seatbelts fastened: Indicates occupants

This data helps emergency services prepare the right response.

Why eCall Matters

Faster Response Times

Studies show eCall can:

• Reduce response times by 40% in rural areas
• Cut response times by 50% in urban areas
• Provide accurate location instantly

Saving Lives

The European Commission estimates eCall could save 2,500 lives per year across Europe by speeding up emergency response.

Works When You Can't

If you're unconscious or trapped, eCall calls for help automatically. The voice channel lets operators assess the situation even if you can't speak.

Which Cars Have eCall?

eCall has been mandatory since April 2018 for all new car models sold in the EU and UK.

• 2018 onwards: All new type-approved cars
• Older cars: May have manufacturer's own emergency system
• Retrofits: Aftermarket eCall devices are available

Manufacturer Emergency Systems

Many carmakers have their own connected emergency services:

• BMW: Intelligent Emergency Call
• Mercedes: Mercedes me emergency
• Volvo: Volvo On Call
• Tesla: Emergency features via app
• OnStar: GM's system (Vauxhall)

These may offer additional features beyond standard eCall.

Privacy Considerations

eCall only transmits data when activated. It doesn't:

• Track your location continuously
• Share data with third parties
• Activate without a crash or manual button press

The system is "dormant" until needed.

Common Questions

What if there's no mobile signal?

eCall uses 112, which can connect via any available network – not just your own provider.

Does it work abroad?

Yes. eCall works throughout Europe, connecting to local emergency services.

Can I test it?

No – the SOS button should only be used in emergencies. Test calls may result in emergency services being dispatched.

What if it activates by mistake?

Stay on the line and explain to the operator. False alarms are rare as the system requires significant impact forces.

The Future of eCall

Next generation eCall will include:

• More detailed crash data
• Information about crash severity
• Data to help hospitals prepare
• Integration with advanced safety systems

eCall is one of many safety features in modern cars. Learn more about other systems in our guide to advanced driver assistance systems.
