The 2018 Honda CR-V uses a Tire Pressure Monitoring System (TPMS) that alerts you when a tire is under-inflated, and, on most trims, it can display which tire is low on the vehicle’s information screen. This helps you pinpoint the problem without guessing from the warning light alone.
How the system works in the 2018 CR-V
The CR-V has a direct TPMS with sensor-equipped tires. When one tire drops below the recommended pressure, the TPMS warning light on the dash comes on. In many configurations, you can also call up a per-tire readout on the driver information display or center screen to see the pressure in each tire and identify the low one.
Can it identify which tire is low?
Yes. In many 2018 CR-V trims, you can view the individual tire pressures on the vehicle’s information display. The screen typically shows a graphic of the car with each tire’s PSI, and the low tire is highlighted or labeled (e.g., LF, RF, LR, RR for left-front, right-front, left-rear, right-rear).
To help you locate the low tire, here are practical steps you can follow on most 2018 CR-V trims.
- Turn on the ignition and navigate to the Tire Pressure/TPMS screen using the INFO or Menu button on the steering wheel.
- Select the Tire Pressure or TPMS option to view the four tire readings (front-left, front-right, rear-left, rear-right).
- Look for the tire with the lowest pressure or a highlighted tire icon; the display may label it as LF, RF, LR, or RR.
- Compare the readings with the recommended PSI shown on the door placard or in the owner’s manual; inflate any tire that sits significantly below spec.
Note: The exact path to the per-tire data can vary by trim level and infotainment setup. If your screen only shows a general warning, rely on the standard TPMS light and physically check all tires with a gauge.
In summary, the CR-V can tell you which tire is low when the per-tire data is available on your display, but the primary indicator remains the dashboard TPMS warning light if you don’t access the detailed readout.
What to do if your screen doesn’t show per-tire data
If your 2018 CR-V displays only the generic TPMS warning without per-tire details, you should still address the warning promptly. Inflate all tires to the recommended pressure and verify the readings with a tire gauge. The recommended pressures are on the door jamb placard and in the owner's manual. If the warning persists after inflation, inspect for leaks or take the vehicle to a dealer or tire shop for a precise diagnostic.
- Inflate each tire to the recommended cold PSI before driving long distances.
- Recheck the pressures after a short drive to ensure the TPMS has updated.
- If a tire continues to show low pressure or you suspect a leak, have it inspected by a professional.
Even without on-screen per-tire data, the TPMS serves as an early alert, and the standard procedure of checking and adjusting tire pressure remains essential for safety and fuel efficiency.
Summary
The 2018 Honda CR-V typically confirms which tire is low through the TPMS and, on many trims, by displaying per-tire pressures on the driver information display or center screen. If the detailed readout isn’t visible, the dashboard warning still signals a low tire, and you should manually check and inflate all tires to the recommended levels. Regularly monitor tire pressures to maintain safety and performance.
