What the Steering Lock Warning Light Means on a Smart ForFour
The steering lock warning light on a Smart ForFour indicates a fault with the electronic steering column lock, which can prevent the car from starting or the wheel from unlocking. It is common on keyless-start vehicles.
How Urgent Is the Steering Lock Warning Light?

A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing.

Frequently Asked Questions
Why is the Steering Lock Warning Light on in my Smart ForFour?
The Steering Lock Warning Light illuminates on a Smart ForFour when the vehicle detects a condition in the related system that is outside its normal range. The exact reason can vary from something as minor as a loose connection to a component that needs replacing, which is why reading the stored trouble codes is the reliable way to know for certain.
Can I keep driving with the Steering Lock Warning Light on?
For a Smart ForFour, a steady amber Steering Lock Warning Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Steering Lock Warning Light on a Smart ForFour?
There is no single price for the Steering Lock Warning Light on a Smart ForFour; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Steering Lock Warning Light reset itself on a Smart ForFour?
Sometimes the Steering Lock Warning Light on a Smart ForFour clears on its own once the condition that triggered it no longer exists — for example after several good drive cycles. More often, though, the light stays on until the underlying fault is repaired and the code is cleared, so treat a self-clearing light as a reason to still investigate.
