Product Overview
Our Traffic Jam Assist retrofit brings genuine JLR congestion assistance to your existing vehicle. We use original equipment control modules, update the electric power steering and adaptive cruise systems, and load factory calibration files. The result matches a vehicle built with Traffic Jam Assist from the factory.
You operate the system through the existing steering wheel cruise controls and the driver assistance menu. When traffic slows below a set threshold, the vehicle provides continuous steering support while managing speed and braking. No aftermarket controllers or visible modifications appear anywhere in the cabin.
What the Retrofit Includes
- Genuine JLR steering control module update for low-speed lane centering
- Adaptive cruise control module integration for traffic following
- Camera and radar sensor configuration update
- Factory specification wiring harnesses and connectors where required
- Vehicle configuration file update
- Full sensor calibration and road testing in traffic conditions
How Traffic Jam Assist Works
Traffic Jam Assist builds on the Adaptive Cruise Control with Stop system. The front camera and radar sensors detect lane markings and the vehicle ahead. When you drive at speeds below approximately 37 mph in congested traffic, the system activates steering assistance. It keeps your vehicle centred within the lane while the adaptive cruise manages acceleration and braking to match the traffic flow.
You keep your hands lightly on the steering wheel. The system provides continuous guidance through gentle steering inputs, reducing the constant corrections usually needed in slow traffic. If the lane markings disappear, the system follows the vehicle ahead using the radar sensor. The driver information display shows the active status and prompts you to take full control when conditions change.
The vehicle recognises the retrofit as original equipment through the driver assistance and chassis networks. The steering, braking, and acceleration work together seamlessly.

Installation and Programming
LR-Retrofit technicians complete the installation at our workshop. This retrofit typically requires no additional physical hardware. We update the steering, adaptive cruise, and camera modules using JLR diagnostic equipment. We then calibrate the sensors and configure the driver assistance menu. Finally, we conduct a road test in real traffic conditions to verify smooth steering assistance and correct speed control.
