This is usually informational. Address it at your convenience.
What the Security / Anti-Theft Light Means on a Citroen SpaceTourer
On the Citroen SpaceTourer, this symbol relates to the anti-theft system. A slow blink when parked is normal deterrent behaviour; erratic flashing or a no-start suggests a fault with the key or alarm module.
How Urgent Is the Security / Anti-Theft Light?
Urgency level for this indicator on the Citroen SpaceTourer: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Security / Anti-Theft Light appeared, how the Citroen SpaceTourer is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

How to Fix the Security / Anti-Theft Light on a Citroen SpaceTourer
The right way to clear the Security / Anti-Theft Light on a Citroen SpaceTourer is to fix the underlying cause, not just reset the symbol. Work through the steps below in order — they move from the simplest checks any driver can do to the diagnostic work best left to a scan tool. Following this sequence prevents the classic mistake of replacing expensive parts before ruling out the cheap, common problems first.
- Replace the key fob battery
- Lock/unlock with the key in the door to reset the alarm
- Check the bonnet and door switches for false triggers
- Test the vehicle battery
- Have the alarm/immobiliser module scanned if it persists
Is It Safe to Drive With the Security / Anti-Theft Light On?
Whether it is safe to keep driving your Citroen SpaceTourer with the Security / Anti-Theft Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Citroen SpaceTourer is running poorly, stop somewhere safe and arrange help rather than pushing on. If the light is amber and the car drives normally, you generally have time to reach a workshop — but 'have time' is not the same as 'ignore it', so book a check promptly.
Professional Mechanic Tips
A slow, steady blink while parked is the alarm doing its job as a deterrent — that one is completely normal.
Random alarm triggers on a Citroen SpaceTourer often trace to a faulty bonnet switch fooling the system into thinking it is being opened.
Frequently Asked Questions
Why is the Security / Anti-Theft Light on in my Citroen SpaceTourer?
The Security / Anti-Theft Light illuminates on a Citroen SpaceTourer 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 Security / Anti-Theft Light on?
For a Citroen SpaceTourer, a steady amber Security / Anti-Theft 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 Security / Anti-Theft Light on a Citroen SpaceTourer?
Cost varies widely because the Security / Anti-Theft Light can stem from several causes on a Citroen SpaceTourer. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour. Getting the specific trouble code first is what lets a shop quote accurately instead of estimating blind.
Will the Security / Anti-Theft Light reset itself on a Citroen SpaceTourer?
Sometimes the Security / Anti-Theft Light on a Citroen SpaceTourer 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.
