Ever had your Mazda CX-5 show the “Tyre Pressure Warning Light” on the dashboard even after checking and inflating the tyres? You’re not alone. This can be frustrating—especially if you don’t know how to reset it.
In this guide, you’ll learn exactly how to reset the tyre pressure system (TPMS) on a Mazda CX-5, common reasons the light might stay on and some helpful tyre tips for Kenyan roads.
What Does the Tyre Pressure Warning Light Mean?
The Tyre Pressure Monitoring System (TPMS) on the Mazda CX-5 is designed to alert you when one or more tyres are underinflated. This is a critical safety feature that helps:
- Improve fuel efficiency,
- Prevent tyre wear,
- Avoid accidents caused by low tyre pressure.
Once you’ve inflated your tyres to the correct pressure, you may still need to manually reset the TPMS to turn off the warning light.
How to Reset Tyre Pressure Light on a Mazda CX-5 (All Model Years)
The reset process may vary slightly depending on your model year but here’s a general method that works for most Mazda CX-5 vehicles, including Kenyan imports (2013–2023 models):
Step-by-Step Reset Instructions
1. Check and Adjust Tyre Pressure
- Park your car on a level surface.
- Check the pressure of all four tyres using a reliable pressure gauge.
- Inflate each tyre to the recommended PSI (check the sticker on the driver’s door frame or your owner’s manual—usually around 34 PSI for most CX-5 models).
- Don’t forget the spare tyre—some models monitor that too.
2. Start the Engine
- Turn the ignition to the “ON” position without starting the engine.
- In push-to-start models, press the start button without pressing the brake pedal.
3. Locate the TPMS Reset Button
- Look under the dashboard (below the steering wheel) or near the centre console.
- The button is usually labeled “SET” or has a tyre icon.
4. Press and Hold the Reset Button
- Press and hold the button until the TPMS indicator blinks slowly (usually about 3–5 seconds).
- Once the light blinks, release the button.
5. Drive the Car* Drive for about 10–15 minutes at speeds above 30 km/h to allow the system to recalibrate.
If There’s No Reset Button?
Some newer Mazda CX-5 models automatically reset the TPMS after correcting the tyre pressure and driving for a few minutes. If the warning light stays on:
- Check for slow leaks or punctures.
- Re-check all tyre pressures.
- Consider visiting a tyre specialist to scan or recalibrate the system.
Common Reasons the Light Stays On
- Tyre pressure not correct after refill
- Faulty TPMS sensor
- Dead sensor battery (common in older or imported models)
- Changed wheels without syncing sensors
- Sudden temperature changes affecting pressure readings
Tyre Care Tips for Kenyan Roads
Driving in Kenya means dealing with potholes, rough terrain, and hot weather—so tyre care is extra important:
- Check your pressure monthly, especially before long trips.
- Avoid underinflation, which is common in hot climates.
- Rotate your tyres every 10,000 km to ensure even wear.
- Replace worn-out tyres before the rainy season begins.
