What the Cruise Control Light Means on a Subaru WRX

On the Subaru WRX, this symbol means cruise control is enabled. Colour often indicates state — armed versus actively maintaining your set speed.

How Urgent Is the Cruise Control Light?

How worried should you be? For the Cruise Control Light on a Subaru WRX, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Subaru WRX still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.

Common Symptoms Alongside the Cruise Control Light

When the Cruise Control Light shows up on a Subaru WRX, it rarely arrives completely alone — there are usually subtle clues if you know where to look. Drivers often notice a change in how the Subaru WRX responds, an unfamiliar sound, or a warning message on the instrument cluster. Cataloguing these symptoms is not busywork; each one narrows the list of likely causes and helps a technician zero in on the real fault instead of replacing parts on a hunch.

  • Cruise symbol lit when system on
  • Set-speed indicator shown
  • No fault behaviour normally

What Causes the Cruise Control Light to Come On?

The Cruise Control Light on the Subaru WRX can be triggered by several conditions, and experienced technicians work through them from most to least likely. Some causes are trivial and cost almost nothing to correct, while others require replacing a sensor or component. The list below reflects what actually turns this light on in the real world, so you can gauge whether you are likely facing a quick fix or a workshop visit.

  • Cruise control switched on (normal)
  • Brake light switch fault (can disable cruise)
  • Speed sensor fault

How to Fix the Cruise Control Light on a Subaru WRX

The right way to clear the Cruise Control Light on a Subaru WRX 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.

  1. Confirm you switched cruise control on
  2. Tap the brake to cancel and re-set as needed
  3. If cruise will not engage, check the brake light switch
  4. Scan for speed sensor faults if it drops out
  5. Repair the switch or sensor as diagnosed

Is It Safe to Drive With the Cruise Control Light On?

Whether it is safe to keep driving your Subaru WRX with the Cruise Control Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Subaru WRX 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

Field notes from Marcus Vale, ASE-Certified Master Technician
If cruise on a Subaru WRX refuses to set, a failing brake light switch is the usual reason — the car thinks you are braking.
Cruise disengages the instant you touch the brake or clutch; that is by design, not a fault.

Frequently Asked Questions

Why is the Cruise Control Light on in my Subaru WRX?

The Cruise Control Light illuminates on a Subaru WRX 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 Cruise Control Light on?

Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Subaru WRX, the safe choice is to stop and have it checked rather than risk further damage.

How much does it cost to fix the Cruise Control Light on a Subaru WRX?

Cost varies widely because the Cruise Control Light can stem from several causes on a Subaru WRX. 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 Cruise Control Light reset itself on a Subaru WRX?

Occasionally, yes — a Subaru WRX can extinguish the Cruise Control Light by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
