Infiniti vehicles are equipped with a sophisticated system of warning lights and symbols designed to keep drivers informed about the status of various vehicle systems. These indicators play a crucial role in maintaining the safety, performance, and longevity of your Infiniti. Understanding what each symbol means can help you address potential issues promptly, preventing minor problems from escalating into major repairs.
The dashboard of your Infiniti serves as a communication hub, alerting you to everything from routine maintenance needs to critical safety concerns. These warning lights are color-coded for easy interpretation: red typically indicates an urgent issue requiring immediate attention, yellow or amber suggests caution and the need for service soon, while green and blue lights are generally informational.
Let’s explore some of the most common Infiniti warning lights and their meanings to help you navigate your vehicle’s health more effectively.
| Light Color | General Meaning |
|---|---|
| Red | Urgent issue, immediate attention required |
| Yellow/Amber | Caution, service needed soon |
| Green/Blue | System active or functioning normally |
Critical Red Warning Lights
Red warning lights on your Infiniti’s dashboard demand immediate attention. These indicators signal issues that could compromise your safety or cause severe damage to your vehicle if ignored. Understanding these critical warnings is essential for every Infiniti owner.
Brake System Warning Light
The brake system warning light is one of the most crucial indicators on your dashboard. When illuminated, it could signify several issues:
- Low brake fluid level
- Engaged parking brake
- Malfunction in the brake system
If this light comes on while driving, it’s imperative to pull over safely as soon as possible. Continuing to drive with brake issues can be extremely dangerous. Check if the parking brake is fully released. If the light remains on, do not attempt to drive further. Contact roadside assistance or a professional mechanic immediately.
Engine Oil Pressure Warning Light
The engine oil pressure warning light resembles an oil can and indicates a potentially serious issue with your engine’s oil system. This light may illuminate due to:
- Critically low oil level
- Oil pump failure
- Oil pressure sensor malfunction
If you see this light while driving, stop the engine immediately. Continuing to operate the vehicle could result in severe engine damage. Check the oil level using the dipstick, and add oil if necessary. If the oil level is normal but the light persists, have your vehicle towed to an Infiniti service center for inspection.
Battery Charge Warning Light
The battery charge warning light typically looks like a battery symbol. When lit, it indicates issues with your vehicle’s charging system, which could be caused by:
- Faulty alternator
- Loose or damaged drive belt
- Battery problems
If this light comes on while driving, turn off non-essential electrical components to reduce battery drain. Proceed to a safe location and have your vehicle inspected as soon as possible. Continuing to drive risks leaving you stranded if the battery depletes completely.
Amber Warning Lights: Caution Required
Amber or yellow warning lights in your Infiniti indicate issues that require attention but are generally less urgent than red warnings. These lights often relate to vehicle systems that affect performance, efficiency, or long-term reliability.
Check Engine Light (Malfunction Indicator Lamp)
The Check Engine Light, also known as the Malfunction Indicator Lamp (MIL), is perhaps the most recognizable warning light. It can illuminate for various reasons, including:
- Loose gas cap
- Faulty oxygen sensor
- Catalytic converter issues
- Ignition system problems
While not always an emergency, the Check Engine Light should not be ignored. If it’s flashing, reduce speed and have your vehicle checked immediately, as this indicates a severe misfire that could damage the catalytic converter. If steady, schedule a diagnostic check soon to prevent potential damage and maintain optimal performance.
Tire Pressure Monitoring System (TPMS) Light
The TPMS light looks like a tire cross-section with an exclamation point. It alerts you when one or more tires have significantly low pressure. Proper tire inflation is crucial for:
- Optimal fuel efficiency
- Even tire wear
- Safe handling and braking
When this light comes on, check your tire pressures as soon as possible and inflate them to the recommended levels found in your owner’s manual or driver’s door jamb. If the light persists after proper inflation, there may be a leak or a problem with the TPMS sensor.
Anti-lock Braking System (ABS) Warning Light
The ABS warning light indicates a potential issue with your Anti-lock Braking System. While your regular brakes will still function, the anti-lock feature may be compromised. This could affect your vehicle’s ability to maintain steering control during hard braking, especially on slippery surfaces.
If this light comes on:
- Drive cautiously, especially in wet or icy conditions
- Avoid sudden, hard braking
- Have your ABS system checked by a qualified technician as soon as possible
Vehicle Dynamic Control (VDC) Warning Light
The VDC warning light relates to Infiniti’s stability control system. When illuminated, it could mean:
- The system is actively working to maintain vehicle stability
- There’s a malfunction in the VDC system
If the light flashes while driving, it means the VDC system is engaged, typically on slippery roads. If it stays on constantly, have your vehicle inspected, as the stability control system may not function properly when needed.
Informational Green and Blue Lights
Not all dashboard lights indicate problems. Green and blue lights typically provide information about active systems or features in your Infiniti.
High Beam Indicator
The high beam indicator, usually blue, simply confirms that your high beam headlights are active. Remember to switch back to low beams when approaching oncoming traffic or following other vehicles closely to avoid blinding other drivers.
Turn Signal Indicators
Green turn signal indicators flash to confirm that your left or right turn signals are active. If one side blinks faster than usual, it often indicates a burnt-out bulb that needs replacement.
Cruise Control Indicator
The cruise control light illuminates green when the system is active, helping you maintain a constant speed without keeping your foot on the accelerator. Some Infiniti models feature advanced adaptive cruise control, which may have additional indicators for following distance and system status.
Hybrid System Indicators
For Infiniti hybrid models, additional lights provide information about the hybrid system’s status and operation.
Ready Indicator
The READY indicator is crucial for hybrid vehicles. It signals that the hybrid system is operational and the vehicle is ready to drive. This light should come on after starting the car and indicates that it’s safe to put the vehicle in gear.
EV Mode Indicator
Some hybrid Infinitis have an EV mode indicator that shows when the vehicle is operating solely on electric power. This typically occurs at low speeds or when the battery has sufficient charge for electric-only operation.
Maintenance and Service Indicators
Infiniti vehicles also feature lights to remind you of routine maintenance needs, helping you keep your vehicle in optimal condition.
Service Engine Soon Light
Unlike the Check Engine Light, the Service Engine Soon indicator is often related to scheduled maintenance or minor issues. It may illuminate when your vehicle is due for an oil change, air filter replacement, or other routine services.
Intelligent Key Warning
Many Infiniti models use an Intelligent Key system. If you see a key symbol on your dashboard, it could indicate:
- The key is not detected in the vehicle
- The key battery is low
- There’s a malfunction in the key system
Always ensure you have your key with you and replace the battery when needed to avoid potential starting issues.
