Does the Grenadier share ADAS with BMW?

No. BMW supplies engines (B58 petrol, B57 diesel), but the ADAS system is bespoke — engineered by Magna Steyr for the Grenadier. BMW calibration procedures do not apply. The Quartermaster uses identical ADAS hardware. See all INEOS models

What changed with the 2026 Grenadier ADAS2?

The 2026 model adds active Lane Assist (applies braking to centre the vehicle when solid lane markings are detected) and a mirror-mounted Driver Monitoring Camera with infrared tracking. These create two new calibration points compared to earlier models.

Will a bull bar definitely affect my Grenadier's ADAS?

Not always, but it can. Large bull bars may partially obstruct the camera's field of view. If ADAS warnings appear after fitting, a calibration check confirms whether the camera can still see the road accurately through the bar.

INEOS Grenadier ADAS Calibration — £199

Ineos Automotive Grenadier ADAS Calibration

INEOS states it plainly in their owner documentation: aftermarket windscreen replacement requires genuine glass and mandatory ADAS camera recalibration. For a body-on-frame off-roader designed to take stone chips on trails, river crossings, and farm tracks, that directive triggers more frequently than on any road-biased SUV. The Grenadier's forward-facing camera is the single most critical ADAS sensor – and windscreen damage is part of the ownership experience.

ADAS Systems on Your INEOS Grenadier

The Grenadier uses a primarily camera-based ADAS architecture. The 2026 model year introduces ADAS2 with enhanced features:

Automatic Emergency Braking / Collision Detection – camera-based forward collision prevention
Lane Departure Warning (LDW) – alerts when drifting across lane markings
Lane Assist (2026+ ADAS2) – applies corrective braking to centre the vehicle within solid lane markings
Adaptive Cruise Control (ACC) – maintains speed and following distance
Intelligent Speed Assist (ISA) – camera-based speed sign detection
Driver Drowsiness Detection (DDD) – monitors driving patterns for fatigue
Driver Monitoring Camera (2026+ ADAS2) – mirror-mounted infrared camera tracking driver attention
Park Assist – ultrasonic sensors front and rear

The forward-facing camera behind the windscreen is the primary ADAS sensor – handling LDW, AEB, ISA, and contributing to ACC. Unlike most manufacturers, INEOS does not appear to use front bumper-mounted radar for core ADAS functions, making this single camera the most critical calibration point.

Common Grenadier Calibration Triggers

Windscreen Replacement – The Most Common Trigger

Off-road use means stone chips, trail debris, and windscreen damage happen more often on a Grenadier than on any road SUV. INEOS explicitly requires genuine glass and professional camera recalibration after every replacement – no exceptions.

Bull Bar and Bumper Guard Installation

Bull bars are one of the most popular Grenadier accessories. They can obstruct the forward camera's field of view or displace front parking sensors. If ADAS warnings appeared after fitting aftermarket front protection, the system needs recalibration to account for altered geometry.

Suspension Lift Kits

A lift kit changes the camera's angle relative to the road surface. LDW, ISA, and AEB depend on the camera reading the road at the correct angle. Post-lift recalibration verifies the camera still functions accurately at the new ride height.

Off-Road Damage

Trail impacts, gate post scrapes, and branch strikes are part of Grenadier life. When bumpers are repaired after off-road damage, the ultrasonic parking sensors need checking and potential recalibration.
