The 2014 Acura ILX is a front-wheel-drive compact luxury sedan. Depending on the trim, it is equipped with either a 2.0L 4-cylinder engine (R20A5, 150 hp) paired with a 5-speed automatic transmission, or a 2.4L 4-cylinder engine (K24Z7, 201 hp) paired with a 6-speed manual transmission for the performance-oriented ILX .
This guide prioritizes factual accuracy derived from OEM documentation and verified technical sources, providing the complete factory service schedule based on the 2014 Acura ILX Owner's Manual, including Maintenance Minder codes, fluid specifications, and critical service intervals. Always consult the official Owner's Manual in your vehicle for the most authoritative information.
Key Takeaways
- The 2014 ILX uses the Maintenance Minder system instead of fixed odometer intervals. The vehicle's computer monitors driving conditions and displays alphanumeric codes (A, B, 1‑5) when specific services are due. There is no traditional "every 30,000-mile" service schedule.
- Brake fluid replacement is time-sensitive, not mileage-sensitive. Independent of the Maintenance Minder, replace brake fluid every 3 years regardless of mileage .
- The 2.4L (manual transmission) model has a timing chain, NOT a belt. Unlike older Acura V6 engines, the 2.4L's timing chain requires no scheduled replacement. Code 4 on the Maintenance Minder covers only spark plugs and valve clearance inspection.
- For the 2.0L (automatic) model, always confirm transmission fluid specifications with your dealer. The 5-speed automatic may require Honda-specified ATF rather than universal fluids .
- If no service message appears within 12 months, change the engine oil at least once per year regardless of mileage .

Understanding the Maintenance Minder System
The 2014 Acura ILX does not have a traditional fixed‑mileage maintenance schedule. Instead, Acura employs a Maintenance Minder system that monitors vehicle operating conditions (engine temperature, speed, time, and driving habits) and calculates when service is required .
How the System Works
When the oil life reaches 15%, a wrench symbol illuminates on the dashboard, and the system displays alphanumeric codes indicating exactly which services are due .
| Oil Life Remaining | Message Displayed | Recommended Action |
|---|---|---|
| 15% | SERVICE DUE SOON | Service should be scheduled soon |
| 5% | SERVICE DUE NOW | Maintenance should be performed immediately |
| 0% | SERVICE PAST DUE | Service is overdue – schedule immediately |
Fallback Time Requirements
If a SERVICE message does not appear within 12 months after the display is reset, change the engine oil at least once per year regardless of mileage .
Maintenance Minder Codes
The Maintenance Minder communicates service needs through alphanumeric codes. A code consists of a main item (A or B) followed by sub‑item numbers (1 through 6) .
Main Item Codes (A, B)
| Code | Required Service |
|---|---|
| A | Replace engine oil |
| B | Replace engine oil and oil filter; inspect front and rear brakes; check parking brake adjustment; inspect tie rod ends, steering gearbox, and boots; inspect suspension components; inspect driveshaft boots; inspect brake hoses and lines (including ABS/VSA); inspect all fluid levels and condition of fluids; inspect exhaust system; inspect fuel lines and connections |
Sub-Item Codes (1-6)
| Code | Service Description | Notes |
|---|---|---|
| 1 | Rotate tires | Standard tire rotation |
| 2 | Replace air cleaner element; replace dust and pollen filter; inspect drive belt | If you drive in dusty conditions, replace air cleaner element more frequently |
| 3 | Replace transmission fluid | Check owner's manual for your transmission type |
| 4 | Replace spark plugs; inspect valve clearance | NOTE: On the 2.4L manual model, timing belt replacement does NOT apply (timing chain) |
| 5 | Replace engine coolant | Standard coolant replacement interval |
| 6 | Replace rear differential fluid | NOT APPLICABLE – ILX is FWD only |
Independent Maintenance Requirements
The following requirements apply independently of the Maintenance Minder system:
| Requirement | Interval |
|---|---|
| Brake fluid | Replace every 3 years regardless of mileage |
| Idle speed | Inspect every 160,000 miles (256,000 km) |
Engine Oil Change Guidance
Factory Requirements
| Specification | Detail |
|---|---|
| Recommended oil | SAE 0W‑20 premium-grade detergent oil with API Certification Seal |
| Oil capacity (with filter) | 3.7 liters (3.9 quarts) |
| Oil change trigger | Maintenance Minder code A or B (when oil life reaches 15%) |
| Maximum time interval | If no service indicated within 12 months, change oil at least once per year |
How to Check Oil Level
- Park on level ground and wait at least 3 minutes after engine shutdown
- Pull out the dipstick and wipe completely clean
- Reinsert fully, then remove again
- Oil level should be between the upper and lower marks
Owner Guidance
- Acura Genuine Motor Oil is recommended, though any synthetic oil of the same viscosity grade and API certification is acceptable
- Your Acura does not require any oil additives
- Check the engine oil level at least once per month—or every time you refuel
Transmission Service
5-Speed Automatic Transmission (2.0L Engine)
The 2.0L ILX is equipped with a conventional 5-speed automatic transmission.
| Specification | Detail |
|---|---|
| Replacement trigger | Maintenance Minder code 3 |
| Fluid type | Use only Honda-specified ATF – do not use universal DEXRON fluids |
| Important warning | Universal fluids (e.g., DEXRON-VI) are not recommended for Honda/Acura transmissions unless specifically approved |
6-Speed Manual Transmission (2.4L Engine)
| Specification | Detail |
|---|---|
| Replacement trigger | Maintenance Minder code 3 |
| Fluid type | Honda Manual Transmission Fluid (MTF) or equivalent |
| Capacity | Consult owner's manual |
Spark Plug Replacement
| Specification | Detail |
|---|---|
| Replacement trigger | Maintenance Minder code 4 |
| Inspect valve clearance | Code 4; adjust if necessary |
| Timing belt replacement | Not applicable for 2.4L – 2.4L uses timing chain |
Owner Guidance: The ILX's engines have a "no scheduled tune-ups for extended intervals" design under normal operation. If you notice rough idle, reduced fuel economy, or hesitation before the Maintenance Minder indicates replacement, have the plugs inspected early. Use only OEM-specified spark plugs (NGK or Denso equivalents).
Engine Coolant Service
| Specification | Detail |
|---|---|
| Replacement trigger | Maintenance Minder code 5 |
| Coolant type | Acura Long Life Antifreeze/Coolant Type 2 |
| Mixture | 50/50 with distilled water |
| Checking level | Check coolant level in the reserve tank at each fuel fill |
Owner Guidance: Do not add straight antifreeze or water; the factory coolant is premixed. If Acura coolant is unavailable, a major brand of non‑silicate coolant may be used as a temporary replacement; return to Genuine Acura coolant as soon as possible.
Brake Fluid Replacement
| Specification | Detail |
|---|---|
| Replacement trigger | Every 3 years regardless of mileage – independent of Maintenance Minder |
| Specified fluid | Honda Heavy Duty Brake Fluid DOT 3 |
| Temporary substitute | DOT 3 or DOT 4 from a sealed container |
| DOT 5 warning | NOT compatible – never use DOT 5 fluid (silicone-based) |
Why it's critical: Brake fluid is hygroscopic – it absorbs moisture from the air over time. This moisture lowers the fluid's boiling point (potential brake fade under hard braking) and promotes internal corrosion of the brake system .
Owner Guidance: A complete system flush (draining old fluid from each caliper) is required. Topping off the reservoir is not sufficient. Check the brake fluid level monthly and keep between MIN and MAX marks.
Drive Belt Inspection
| Specification | Detail |
|---|---|
| Inspection trigger | Maintenance Minder code 2 (inspect drive belt) |
| Replacement | Replace if cracked, frayed, glazed, or making a squealing noise on startup |
Owner Guidance: The ILX uses a serpentine drive belt that powers the alternator, power steering pump, and A/C compressor. Most drive belts last between 60,000 and 90,000 miles, but the Maintenance Minder indicates when inspection is needed.
Air Filters (Engine & Cabin)
| Filter | Replacement Trigger | Severe Conditions Note |
|---|---|---|
| Engine air cleaner element | Maintenance Minder code 2 | If you drive in dusty conditions, replace more frequently |
| Cabin air filter (dust and pollen filter) | Maintenance Minder code 2 | If you drive in urban areas with high soot concentrations, replace more frequently |
Owner Guidance: Both filters are inexpensive and can be replaced without special tools. The cabin air filter is typically located behind the glove box. A clogged engine air filter can reduce fuel economy and engine performance.
Resetting the Maintenance Minder Display
After performing the required maintenance service, the engine oil life display must be reset. Failure to reset results in the system showing incorrect maintenance intervals.
Reset Procedure
- Set the power mode to ON (do not start the engine)
- Navigate to the MAINTENANCE INFO screen using the information display buttons
- Press and hold the appropriate button until the oil life reset mode is displayed
- Select RESET, then confirm
- The engine oil life display returns to 100%
> Note: If someone other than a dealer performs maintenance service, reset the engine oil life display yourself. Your dealer will do this automatically if they perform the service.
Monthly & Pre-Drive Checks
As outlined in the 2014 ILX Owner's Manual, perform these checks regularly:
| Frequency | Check Item |
|---|---|
| Monthly | Brake fluid level |
| Monthly | Tire pressure (including spare); examine tread for wear |
| Monthly | Exterior lights operation |
| Pre-drive | Engine oil level |
| Pre-drive | Windshield washer fluid level |
| Pre-drive | Tires for damage or excessive wear |
| Pre-drive | Fluid leaks under vehicle |
Tire Pressure Monitoring System (TPMS)
The 2014 ILX is equipped with a Tire Pressure Monitoring System (TPMS) that monitors each tire's pressure individually.
Understanding TPMS Warnings
| Indicator Behavior | Meaning | Action |
|---|---|---|
| Solid / Steady on | One or more tires is significantly under-inflated | Stop as soon as possible, check tire pressures, and inflate to proper level |
| Flashing (blinks for ~1 minute then stays steady) | System malfunction within TPMS itself | Have system inspected by dealer; often occurs after tire/wheel replacement |
> Note: The TPMS is not a substitute for proper tire maintenance—it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger the TPMS warning.
Scheduled Maintenance Summary
Since the ILX uses the Maintenance Minder system instead of fixed intervals, the table below shows reference intervals—always follow your vehicle's displayed Maintenance Minder codes:
| Component | Reference Interval | Maintenance Minder Code |
|---|---|---|
| Engine oil & filter | 7,500-10,000 miles / 12 months | A or B |
