Nissan Dashboard Warning Light Guide

Is a warning light on in your Nissan? For safety, Nissan uses a color-coded system: Red Lights mean stop driving immediately; Amber Lights mean your vehicle requires professional service soon; and Green/Blue Lights indicate active features. For drivers in Streetsboro, OH, our certified technicians recommend immediate attention to any red brake or engine temperature alerts to prevent costly damage.

Level 1: Critical (Stop Driving Immediately)

Engine Temperature

Looks like a red thermostat. This indicates the engine is overheating. Stop driving immediately to prevent permanent engine seizure.

Engine Oil Pressure

Resembles a red oil can. Indicates dangerously low oil levels or sensor failure. Shut off the engine immediately.

Transmission Warning

A red exclamation point in a gear. Indicates serious issues or overheating. Driving while this is active can cause total transmission failure.

Brake System

Labeled “BRAKE” or a red exclamation point in a circle. Indicates your braking system is malfunctioning and requires immediate tow-in service.

Supplemental Air Bag

A person with a sphere in front. Indicates your airbags may not deploy during an impact. This is a critical safety system failure.

Check Engine

A yellow engine block. Triggers for many reasons, from a loose gas cap to engine failure. Visit Nissan of Streetsboro for an OBD-II code reading.

ABS (Anti-lock Braking)

Yellow "ABS" indicator. Your anti-lock system is disabled. Standard braking still works, but safety on wet Ohio roads is compromised.

Battery Charge Warning

Resembles a yellow/red battery. Your battery has a dangerously low charge. If it stays on after driving, your alternator may be failing.

Power Steering (PS)

Streetsboro Service Tip: The Road Salt Factor

In Northeast Ohio, road salt from the Ohio Turnpike and Route 14 can often corrode wheel speed sensors, triggering the ABS and Master Warning lights. If your light comes on after a heavy snowstorm, it’s vital to have your undercarriage inspected and sensors cleaned by a Nissan professional.

Level 3: Advisory (Action Required)

Tire Pressure (TPMS)

Orange exclamation point in a bowl. Very common in Streetsboro when temperatures drop. Check PSI and fill to levels listed on your door jamb.

Fuel Warning Light

Red gas pump icon. You have approximately 30–60 miles remaining. Keeping at least a quarter tank protects your fuel pump from overheating.

Seat Belt Warning

Person wearing a seat belt. Shows an occupant is unbuckled. If it stays on when all are buckled, there may be a seat sensor issue.

Why You Shouldn’t Ignore Nissan Dashboard Warning Lights

They Save You Money

Warning indicators are designed to detect and alert you to potential problems that might require expensive repairs down the line. Pay attention to these lights and you’ll catch a potentially expensive issue, like a transmission replacement, before it ever has a chance to occur. Regular brake fluid checks and pad replacements, as another example, help you avoid crashes and save you from having to pay for brake repairs.

They Keep You Protected

Lights indicating issues with safety features like the airbags or driver assistance technology will help you keep your Nissan safe. Your vehicle’s condition and resale value, not to mention your health, are better protected when every safety feature is working.

Nissan Has Good Warranties

Even a used Nissan or certified pre-owned model will have a portion of the warranty coverage remaining, so why not make use of it? If you see a warning light indicating a problem that your warranty covers, you can get it fixed at no charge.
