Does the Giulia share sensors with the Tonale?

No. The Giulia sits on the proprietary Giorgio platform with unique sensor positions. The Tonale uses a Stellantis CMP-derived platform with different sensor locations. Calibration procedures differ between the two.

Why won't my Giulia's Highway Assist activate?

Highway Assist requires both the front camera and radar to be correctly calibrated, plus adequate lane markings and motorway conditions. If either sensor was disturbed by a repair – even bumper removal for unrelated work – the system will not engage. A diagnostic scan identifies which sensor needs attention.

Is the Giulia's ADAS the same as the Stelvio?

Yes – the Stelvio shares the Giorgio platform and identical ADAS hardware. Sensor positions are the same in both the saloon and SUV body. Calibration procedures are identical, though reference angles differ due to the Stelvio's higher ride height.

Alfa Romeo Giulia ADAS Calibration

The Giulia sits on the proprietary Giorgio platform – the only rear-drive architecture in the Stellantis group, with sensor positions shared by no other brand. A body shop familiar with Peugeot or Citroën ADAS will find the Giulia's sensor layout unfamiliar, because the Giorgio platform was developed before Alfa Romeo joined Stellantis. If your Giulia's Highway Assist stopped engaging after a bumper repair, the radar is in a Giorgio-specific position that requires specialist calibration knowledge.

ADAS Systems on Your Alfa Romeo Giulia

The Giulia (2016+) sits on the Giorgio platform:

Highway Assist System – combines IACC with Lane Centering for Level 2 semi-autonomous motorway driving (MY2020+)
Intelligent Adaptive Cruise Control (IACC) – radar-based adaptive cruise
Forward Collision Warning with Full Stop – automatic emergency braking capable of bringing the vehicle to a complete stop
Lane Centering (LC) – active steering to keep the vehicle centred in its lane
Lane Departure Warning – audible alert when crossing lane markings
Active Blind Spot Assist – rear bumper sensors detecting vehicles in adjacent lanes
Traffic Sign Recognition – camera-based speed limit detection

The front radar sits in a Giorgio-specific bumper position – not the standard Stellantis CMP layout used by the Tonale or Junior. The windscreen camera is behind the rear-view mirror. Highway Assist activates via the left steering wheel button.

Common Giulia ADAS Triggers

Highway Assist Not Engaging

Highway Assist faults are a common Alfa Romeo forum complaint. The system requires both the camera and radar to be precisely aligned – if either was disturbed during bumper work, wheel alignment, or windscreen replacement, Highway Assist will refuse to activate on the motorway. Radar recalibration and camera calibration restore the system.

After Bumper Repair or Front-End Collision

The Giulia's front radar sits in a position unique to the Giorgio platform. Body shops experienced with other Stellantis brands may attempt standard CMP-platform procedures, which do not apply. If IACC stopped working after a repair, the calibration must follow Giorgio-specific targets.

After Windscreen Replacement

Forward Collision Warning, Lane Centering, and TSR depend on the windscreen camera. Every glass replacement requires recalibration – our windscreen calibration at £199 covers this. See all Alfa Romeo models
