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.

Nissan Altima (2013-2025): Red Battery / Charging System Warning

PULL OVER — Do Not Continue Driving

This light means the alternator is NOT charging the battery. The car is running entirely on battery power. Once the battery drains — typically 20-60 minutes of driving — the engine will stall and will not restart. This is NOT a 'check your battery' suggestion — it is a countdown.

What you see: A red battery-shaped icon with + and - symbols

What to Do Right Now

Turn off ALL electrical accessories immediately (radio, A/C, heated seats, phone charger, headlights — switch to daytime running if safe). Drive directly to an auto parts store or mechanic. Do NOT turn off the engine at a stop that you cannot push-start from. The battery is dying by the minute.
