What does a red dashboard light mean?

Red dashboard lights indicate serious issues that require immediate attention. These include oil pressure, engine temperature, and brake system warnings. Pull over safely and address the issue before continuing to drive.

Can I drive with the check engine light on?

A steady check engine light is usually safe for short drives but should be diagnosed soon. A flashing check engine light indicates a serious problem — reduce speed and have the vehicle checked immediately.

How do I reset dashboard warning lights?

Some lights reset automatically after fixing the issue. Others require an OBD-II scanner to clear the code. Always diagnose and fix the underlying problem before attempting to reset any warning light.

What Does All-Wheel Drive (AWD) Warning Light Mean?

Reviewed by automotive technicians · Last updated July 21, 2026

Quick Answer

All-Wheel Drive (AWD) Warning Light = The Symmetrical All-Wheel Drive system has detected a fault. The most common cause is a tire size mismatch — if one tire has a different circumference (due to different tread depth, wrong tire size, or improper tire rotation pattern), the AWD system detects the rotational difference and disables to prevent drivetrain binding. Other causes include a faulty wheel speed sensor, transfer case solenoid failure, or low transmission fluid.

DRIVE WITH CAUTION — Repair Soon

The Symmetrical All-Wheel Drive system has detected a fault. The most common cause is a tire size mismatch — if one tire has a different circumference (due to different tread depth, wrong tire size, or improper tire rotation pattern), the AWD system detects the rotational difference and disables to prevent drivetrain binding. Other causes include a faulty wheel speed sensor, transfer case solenoid failure, or low transmission fluid.

What you see: An orange or red icon showing 'AWD' text, sometimes accompanied by the text 'AWD Disabled' or 'AWD System Needs Attention' on the multi-function display

What to Do Right Now

Reduce speed and avoid sharp turns. If you recently had a tire replaced, check that all four tires are the same brand, model, size, and have similar tread depth — Subaru AWD requires all four tires to have circumference within 1/4 inch of each other. If a tire was replaced due to a flat, the new tire may have full tread while the others are worn — this triggers the AWD warning. You can continue driving but should have the system checked promptly.

Repair Cost Estimate

Option	Est. Cost	Notes
Do It Yourself	$0 (checking tire sizes and tread depth); $20-40 for a tire tread depth gauge	If you have basic tools and mechanical knowledge
Mechanic / Dealer	$100-200 diagnostic; $200-500 per tire if all four need matching replacement; $150-300 for wheel speed sensor replacement; $500-1,200 for transfer case solenoid repair	Includes diagnostic labor + parts

Frequently Asked Questions

Can I drive my Subaru Crosstrek with the AWD Warning light on?

Yes, but with caution. The vehicle will likely operate in front-wheel-drive mode only, reducing traction in slippery conditions. Reduce speed, avoid sharp turns, and have the system diagnosed promptly. Driving for extended periods with the AWD disabled can cause uneven tire wear. Do NOT ignore this light if you live in an area with snow, ice, or frequent rain.

How much does it cost to fix the AWD Warning light on a Subaru Crosstrek?

DIY cost estimate: $0 (checking tire sizes and tread depth); $20-40 for a tire tread depth gauge. Mechanic/dealer estimate: $100-200 diagnostic; $200-500 per tire if all four need matching replacement; $150-300 for wheel speed sensor replacement; $500-1,200 for transfer case solenoid repair. Subaru requires all four tires to match — replacing just one tire on an AWD Subaru often requires replacing all four.

What causes the AWD Warning light to come on in a Subaru Crosstrek?

The #1 cause is a tire size or tread depth mismatch — Subaru's AWD system is extremely sensitive to tire circumference differences (must be within 1/4 inch). Other causes: faulty wheel speed sensor, damaged transfer case solenoid, low or old transmission fluid, or a blown AWD fuse. If you just had a tire replaced due to a flat, the mismatch between the new full-tread tire and the worn existing tires is the likely cause — Subaru recommends replacing all four tires or shaving the new tire to match.
