ACURA RDX OIL LIFE WARNING INDICATORS

Oil Change Interval Every 7,500 – 10,000 Miles or Once / Year if Mileage Not Met
Oil Life Remaining Action Required
15% Service due soon
5% Service due now
0% Service overdue — immediate action

Monitoring your oil life percentage is a simple yet vital part of following the Acura RDX maintenance schedule.

The dashboard display will alert you as your engine oil depletes, with clear warnings at 15%, 5%, and 0% thresholds.
These indicators work hand-in-hand with the recommended Acura RDX oil change interval of every 7,500 to 10,000 miles under normal driving conditions, or at least once a year if the mileage threshold hasn’t been reached.

Staying attentive to these reminders ensures your engine remains properly lubricated and protected, and helps you stay aligned with the full Acura RDX maintenance schedule for long-term performance and reliability.

Acura RDX Maintenance Codes & What They Mean

 

Your Acura RDX is equipped with an intelligent service minder system that uses maintenance codes to alert you when specific services are due. These alerts are tied to the oil life monitor and help ensure your vehicle stays aligned with its factory-recommended Acura RDX maintenance schedule.

Below is a breakdown of the most common Acura RDX maintenance codes you’ll see on your dashboard display:

1 Tire rotation
2 Replace dust/pollen filter, check drive belt, replace air filters

Decoding Acura RDX Service Alerts

 

By referencing this chart, understanding the Acura RDX service codes is as simple as adding the meaning of the letter code to the meaning of the number(s) code.
For example, the Acura RDX B13 Service Code would be compiled of the services next to B, 1 & 3.
 
Adding up to:
  • B : Replace oil & filter, rotate tires, inspect brakes, fluids, parking brake, other components
  • 1 : Tire rotation
  • 3 : Replace transmission & transfer fluid

What Does Acura RDX A1 Service Include?

Often the first service code you’ll encounter as part of the Acura RDX maintenance schedule.

The Acura RDX A1 service code is a simple yet important part of your SUV’s routine care. This maintenance alert is part of the broader Acura RDX maintenance schedule and signals two essential services:

  • “A” stands for an engine oil replacement to maintain optimal lubrication and reduce engine wear.
  • “1” indicates a tire rotation to ensure even tread wear and balanced handling.

When the Acura RDX A1 service code lights up on your dashboard, it’s your vehicle’s reminder that both tasks are due. Staying consistent with these services keeps your RDX running efficiently, extends the life of your tires, and helps preserve long-term engine health.

Incorporating the A1 code into your scheduled maintenance helps you stay ahead of wear and tear while aligning with Acura’s recommended service intervals.

What’s Included in Acura RDX B1 Service?

A common & comprehensive routine checkup, laying the groundwork for long-term care.

The B1 service for the Acura RDX ensures your SUV continues to operate at peak performance by addressing both preventative care and wear-and-tear items:

  • Oil and filter change
  • Tire rotation
  • Front and rear brake inspection
  • Tire pressure check
  • Parking brake adjustment
  • Fluid check and refill

These inspections help identify emerging issues before they affect your drive, enhancing long-term reliability. Regularly scheduling B1 service at the appropriate mileage helps protect your investment, especially when performed by certified technicians who understand Acura’s high standards.

Wrapping up your journey through the Acura RDX maintenance schedule — it’s clear that staying on top of your vehicle’s service needs — whether it’s the routine Acura RDX A1 service code, the more comprehensive Acura RDX B1 service, or any milestone along the Acura RDX maintenance schedule by mileage — is key to preserving performance, safety, and long-term value. But just as important as knowing what to service is knowing where to go.
