What do the fitment ratings mean?

Thatcham illustrates where Autonomous Emergency Braking is fitted in a model range by an oblong box. The left side of the box represents the lowest model in a range - the right hand side, the highest specification, most luxurious model.

GREEN Means Autonomous Emergency Braking is standard fit - buy this model with confidence.
YELLOW Check if the vehicle you wish to buy has Autonomous Emergency Braking fitted - if not you will have to pay for it.
RED CAUTION! Autonomous Emergency Braking not available.

Low		High

At the time of writing, this manufacturer has all three scenarios available on this vehicle. The base model does not have Autonomous Emergency Braking at all, so the box shows a red line on the left hand side. Most mid spec models have Autonomous Emergency Braking as an option (yellow), so make sure you order it when you buy the car. The green line on the right of the box means only the high spec models have it as standard, so you can buy with confidence.

Autonomous Emergency Braking and Forward Collision Warning fitment ratings

These fitment ratings are a guide for anyone purchasing a new car. Both AEB and FCW systems are rated, so please ask the manufacturer before purchase for full information about the operation of the system you are considering. AEB systems will automatically apply braking in an emergency if the driver is unresponsive, and some will also issue a warning. Whereas FCW systems will only issue a warning and apply dynamic brake support once the driver has applied a braking response.
