Ignoring this light could lead to further damage and more costly repairs in the future. Think of it as a general SOS signal from your car – it's saying, "Houston, we have a problem!" So, don't delay – get it checked out.

2. Oil Pressure Warning Light

This symbol, usually depicted as an oil can, indicates a loss of oil pressure in your engine. This is a serious issue because engine oil is essential for lubrication and cooling. Without adequate oil pressure, the engine's internal components can suffer severe damage due to friction and overheating. If this light comes on, it's crucial to pull over immediately in a safe location and turn off the engine. Continuing to drive with low oil pressure can lead to catastrophic engine failure. Check your oil level using the dipstick – if it's low, add oil. However, if the light persists even after adding oil, there may be a more serious underlying problem, such as a faulty oil pump or a leak in the oil system. In this case, it's best to have your Rogue towed to a mechanic for inspection and repair. Think of this light as a red alert – it's indicating a critical situation that requires immediate attention.

3. Coolant Temperature Warning Light

This light, often represented by a thermometer dipped in liquid, warns you that your engine is overheating. Overheating can cause significant damage to your engine, including warped cylinder heads and cracked engine blocks. If this light comes on, pull over as soon as it's safe to do so and turn off the engine. Allow the engine to cool down before checking the coolant level. If the coolant level is low, add coolant. However, if the light persists, it could indicate a more serious problem, such as a leak in the cooling system, a faulty thermostat, or a failing water pump. Driving with an overheating engine can cause irreversible damage, so it's crucial to address this issue promptly. It's like your car is running a fever – you need to cool it down quickly to prevent further harm.

4. Battery Warning Light

The battery warning light, shaped like a battery, indicates a problem with your car's charging system. This could be due to a faulty alternator, a weak battery, or a problem with the wiring. If this light comes on while you're driving, it means your battery isn't being properly charged, and eventually, your car may stall. While you might be able to drive for a short distance, it's essential to get your car checked out as soon as possible. If the light comes on, try turning off any unnecessary electrical components, such as the radio and air conditioning, to conserve battery power. A failing charging system can leave you stranded, so don't ignore this warning. Think of it as your car saying, "I'm running out of juice!"

5. Tire Pressure Monitoring System (TPMS) Light

This symbol, often depicted as a horseshoe-shaped icon with an exclamation point, indicates that one or more of your tires have significantly low tire pressure. Maintaining proper tire pressure is crucial for safe handling, fuel efficiency, and tire longevity. The TPMS light may illuminate if the tire pressure is significantly below the recommended level, usually around 25% below the optimal pressure. When this light comes on, check the pressure in all your tires and inflate them to the recommended pressure, which can be found on a sticker inside your driver's side doorjamb or in your owner's manual. If the light persists after inflating your tires, there may be a problem with the TPMS sensor itself. Driving with low tire pressure can lead to tire damage, reduced fuel economy, and even a blowout, so it's crucial to address this issue promptly. This light is your car's way of saying, "Hey, my shoes are feeling a little flat!"

What to Do When the Engine Light Comes On

Okay, so the dreaded engine light has illuminated on your Nissan Rogue's dashboard. What do you do now? Don't panic! The first step is to assess the situation and try to determine if there are any obvious issues, such as a loose gas cap or a noticeable change in engine performance. Here's a breakdown of the steps you should take:

1. Check the Gas Cap: Believe it or not, a loose or missing gas cap is one of the most common causes of the check engine light. A loose gas cap can cause fuel vapors to leak, which triggers the OBD system to illuminate the light. Simply remove the gas cap and re-tighten it securely. If the light doesn't turn off immediately, it may take a few driving cycles for the system to reset. Think of it as giving your car a little "Oops, my bad!" moment.
2. Notice Any Performance Issues: Pay attention to how your car is driving. Is it running rough? Is it making any unusual noises? Is the engine misfiring or hesitating?
