How to Read Your Subaru Dashboard Warning Lights
Seeing a warning light illuminate on your Subaru dashboard can be confusing, especially when you aren't sure whether you need to stop immediately or simply take note of an informational indicator.
Understanding the difference between critical warning lights and informational or system-status indicators can help you respond appropriately and keep your Subaru performing safely. In this guide, Southern States Subaru explains how to read some of the most important dashboard warning lights, including the Oil Pressure Warning Light, Check Engine Light, RAB Disabled indicator, and EyeSight Off indicator.
What Do Subaru Dashboard Warning Lights Mean?
Your Subaru's instrument panel uses different lights and messages to communicate information about your vehicle. Some indicate a condition that requires immediate attention, while others simply tell you that a particular feature or driver-assistance system is unavailable, disabled, or operating differently than usual.
A helpful rule of thumb is:
Red warning lights: Generally indicate a condition that may require immediate attention.
Yellow or amber warning lights: Often indicate a malfunction, condition, or system that needs attention.
Green or blue indicators: Generally provide information about a system or feature that is operating.
System-status messages: May tell you that a feature such as RAB or EyeSight is unavailable or has been turned off.
The color alone, however, does not tell the entire story. The symbol, accompanying message, vehicle behavior, and your specific owner's manual are all important.
Subaru's Owner Support resources provide access to vehicle information, maintenance guidance, and model-specific resources to help owners understand and care for their vehicles.
Critical Subaru Warning Lights: When You Should Act
Some dashboard warning lights can indicate a condition that could affect your vehicle's mechanical operation or safety. Two of the most important examples are the Oil Pressure Warning Light and Check Engine Light.
Oil Pressure Warning Light
The oil pressure warning light is one of the dashboard indicators you should never ignore.
Engine oil is essential for lubricating and protecting the moving components inside your Subaru's engine. Subaru recommends regularly checking your engine oil level and explains that oil plays an important role in engine performance and longevity.
If the oil pressure warning light illuminates while you're driving, safely pull over as soon as possible and turn off the engine. Continuing to operate the vehicle when there is a potential oil-pressure problem can result in serious engine damage.
What Should You Do if the Oil Pressure Light Comes On?
Safely move your Subaru off the road.
Turn off the engine.
Do not continue driving if the warning remains illuminated.
Check your owner's manual for the correct procedure for your vehicle.
If you're unsure of the cause or the warning persists, contact Southern States Subaru or arrange for professional assistance.
An oil pressure warning is different from a routine reminder to have your oil changed. If you're seeing the actual oil-pressure warning indicator, treat it as a potentially serious condition.
Check Engine Light
The Check Engine Light, also known as the malfunction indicator light, can indicate that the vehicle's engine or emissions-control system has detected a problem.
Subaru specifically advises owners to pay attention when the Check Engine Light illuminates and provides resources to help explain what the light may mean and when service may be appropriate.
A Check Engine Light does not automatically mean that your Subaru has experienced a major engine failure. There can be many possible causes, ranging from relatively minor issues to conditions that require prompt diagnosis.
What Should You Do When the Check Engine Light Comes On?
If your Check Engine Light illuminates:
Pay attention to how your Subaru is operating.
Check whether any additional warning lights or messages appear.
Avoid ignoring the light, particularly if it remains illuminated.
Consult your owner's manual for model-specific information.
Contact Southern States Subaru to determine whether your vehicle should be inspected.
If the Check Engine Light is flashing, or your Subaru is running poorly, losing power, shaking, overheating, or producing unusual noises or smells, take the situation seriously and safely stop driving when appropriate.
Can You Still Drive With the Check Engine Light On?
Whether it is safe to continue driving depends on the circumstances. A steady Check Engine Light does not necessarily mean you must immediately stop, but it should not be ignored.
If the light is accompanied by other warning indicators, noticeable performance problems, or a flashing Check Engine Light, seek professional assistance rather than continuing to drive normally.
Subaru also offers MySubaru Connected Services on select vehicles, which can provide diagnostic alerts when a Check Engine or other warning light appears and may explain whether service should be scheduled.
Informational and System-Status Indicators
Not every dashboard light means that your Subaru has a mechanical emergency.
Modern Subaru vehicles can use indicators to tell you when driver-assistance or parking-safety systems are unavailable, temporarily stopped, or manually disabled. Two examples are RAB Disabled and EyeSight Off.
These indicators are important because they tell you that a feature may not be available-but they do not necessarily mean your engine or vehicle has suffered a mechanical failure.
What Does RAB Disabled Mean?
RAB stands for Reverse Automatic Braking.
Subaru describes RAB as a system that uses rear bumper-mounted sonar sensors to detect objects while the vehicle is moving in reverse. Depending on the vehicle and conditions, the system can provide proximity alerts and may automatically apply the brakes when it determines that a collision with an object is possible.
If you see an RAB Disabled or similar RAB status message, it means the Reverse Automatic Braking function may not currently be available.
Why Might RAB Be Disabled?
RAB may be manually turned off in certain situations. Subaru notes, for example, that turning RAB off may be useful temporarily when connecting a trailer.
Depending on your Subaru model, the system may also become unavailable because of a system condition or because another vehicle system is experiencing a problem.
What Should You Do if RAB Is Disabled?
If RAB is disabled:
Check the dashboard message for additional information.
Confirm whether RAB was intentionally turned off.
Follow the instructions in your owner's manual for your specific Subaru.
Remember that you should not rely on RAB as a substitute for checking your surroundings while reversing.
If the system remains unavailable unexpectedly, contact Southern States Subaru for assistance.
When backing up, always look in the direction of travel and use your mirrors and available camera systems appropriately.
What Does EyeSight Off Mean?
EyeSight Driver Assist Technology is Subaru's suite of driver-assistance features designed to provide additional support while driving. Depending on the vehicle, EyeSight technologies can include features such as Adaptive Cruise Control, Lane Keep Assist, Sway Warning, Pre-Collision Braking, and Pre-Collision Throttle Management.
An EyeSight Off or related warning/message indicates that EyeSight functions may not currently be available.
This is important, but it should be understood differently from a warning such as low oil pressure. An EyeSight-related indicator primarily concerns the availability of driver-assistance technology.
What Should You Do if EyeSight Is Off?
If an EyeSight warning indicator illuminates or flashes, Subaru's owner documentation advises drivers to safely stop, turn off the engine, and restart the vehicle. If the indicator continues to illuminate or flash after restarting, Subaru advises contacting a Subaru retailer for inspection.
Until the system is restored, drive with the understanding that EyeSight functions may not be available.
It's also important to remember that driver-assistance technology is designed to support the driver-not replace attentive driving.
Why RAB and EyeSight Indicators Can Appear Together
RAB and EyeSight are separate technologies, but their availability can sometimes be related.
Subaru documentation notes that when an EyeSight warning indicator illuminates or flashes, the RAB system may not operate on equipped vehicles.
This is one reason it is important to read all dashboard messages and indicators together rather than treating each light as an isolated problem.
For example, if you see both an EyeSight warning and an RAB-related message, your vehicle may be informing you that multiple driver-assistance functions are currently unavailable.
If the condition persists after following the instructions in your owner's manual, a Subaru retailer can inspect the vehicle and determine what service may be needed.
