Pinpointing the Switch
To reach the TPMS reset button, you must physically crawl into the driver’s footwell. The switch is not on the center console or within the digital gauge cluster menus. Instead, look for a small, rectangular button labeled SET. It is located:
- Behind the lower dash panel, roughly parallel to your right knee when seated.
- Near the hood release lever, but situated higher and further back toward the firewall.
- Facing the rear of the vehicle, rather than the floor, which often requires you to reach upward and back to feel the button.
Visual Confirmation Tips
Because the button is black and blends into the surrounding trim, it is easy to miss. If you are struggling to find it in the dark interior, shine your light vertically against the kick panel wall near the OBD-II port. You are looking for a standalone button recessed into the panel. If you feel a switch that requires a small flat-head screwdriver or a firm thumb press, you have identified the correct component.
Master TPMS Calibration for Your 2014 Lexus GX 460 in 6 Simple Steps
The Tire Pressure Monitoring System (TPMS) in your 2014 Lexus GX 460 is a sophisticated safety feature designed to keep you informed about your vehicle’s tire health. However, after rotating your tires, inflating them to the correct PSI, or replacing a sensor, the warning light often remains illuminated on your dashboard. This guide walks you through the precise location of the hidden reset button and the synchronization process required to turn that warning light off and ensure your vehicle is calibrated correctly for the road ahead.
Step 1: Achieving the Correct Tire Pressure
What you need: A high-quality digital tire pressure gauge and an air compressor or service station air pump.
Instructions: Before attempting a reset, you must ensure all four tires—and the full-size spare tire—are inflated to the manufacturer’s recommended specification. For the 2014 Lexus GX 460, this is typically 32 PSI for all tires, but you should verify this by checking the sticker located on the driver’s side door jamb. Using your gauge, verify each tire one by one. Do not skip the spare tire, as it contains an integrated sensor that the Lexus system monitors; if the spare is low, the light will continue to blink or stay solid regardless of the main tires’ status.
Pro Tip: Always check your tire pressure when the tires are “cold,” meaning the vehicle has been parked for at least three hours or driven less than one mile, to ensure an accurate reading.
Step 2: Locating the Hidden Reset Button
What you need: A flashlight or mobile phone light, and a flexible body to reach under the dashboard.

Listen Free for 30 DaysInstructions: The 2014 Lexus GX 460 TPMS reset switch is notoriously difficult to find because it is tucked away underneath the instrument panel. Sit in the driver’s seat and look toward the lower dash area, specifically near the bottom edge, directly above the pedals and toward the left side, near the hood release lever. You are looking for a small, recessed button labeled “SET.” It is often slightly obscured by the plastic trim. Use your flashlight to identify the button; it is usually located in the vicinity of the Odometer/Trip button and the instrument cluster brightness controls, but mounted much lower on the panel near the floor.
Pro Tip: If you are struggling to see it, try lying on your back on the driver’s side floor mat and looking upward toward the base of the steering column trim.
Step 3: Preparing the Vehicle for Calibration
What you need: Your Lexus smart key fob.
Instructions: Once the tire pressures are set to the exact manufacturer specification and the button is located, you must enter the vehicle’s “Ignition On” mode without starting the engine. Push the “Engine Start/Stop” button twice while keeping your foot off the brake pedal. This powers up the electronics, including the TPMS sensor suite, without running the engine. Verify that the TPMS warning light (the horseshoe-shaped icon with an exclamation point) is illuminated on the dashboard. If the light is blinking, it indicates a system malfunction; if it is solid, it is simply waiting for a reset to recognize the new tire pressure values as the new baseline.
Pro Tip: Ensure that all doors, the hood, and the rear liftgate are fully closed, as open sensors can sometimes interrupt the electronic initialization process.
Step 4: Initiating the Reset Sequence
What you need: Your finger and patience.
Instructions: With the ignition in the “On” mode, locate the TPMS reset button you identified in Step 2. Press and hold this button firmly. You must hold it continuously for exactly three to five seconds. While holding the button, observe the dashboard instrument cluster. The TPMS warning light will begin to blink slowly. This flashing indicates that the vehicle’s onboard computer is effectively erasing the old tire pressure memory and preparing to sample the signals coming from the sensors in your wheels. Do not release the button until you see the blinking pattern start, confirming the system has accepted the command to begin the learning phase.
Pro Tip: If the light does not start blinking after five seconds, release the button, turn the ignition off, wait thirty seconds, and try the sequence again.
Step 5: Completing the Initialization Drive
What you need: A clear, safe stretch of road for driving.

See Annual PlansInstructions: After the light blinks and you release the button, keep the ignition in the “On” position for a few minutes before driving, or simply start the car normally to begin your trip. The sensors require the vehicle to be in motion to “wake up” and transmit their updated pressure data to the Lexus ECU. Drive the vehicle at speeds above 25 mph for approximately 10 to 20 minutes. During this time, the car is performing an automated handshake with each of the five sensors. The TPMS light should extinguish on its own once the system successfully correlates the sensor IDs with the current tire pressures.
Pro Tip: Avoid stop-and-go city traffic if possible; a steady speed on a highway or long road allows the sensors to communicate more consistently without interruption.
Step 6: Verifying the System Status
What you need: Visual confirmation of the dashboard.
Instructions: After completing the drive cycle, check your instrument cluster. The TPMS warning light should be completely off. If the light remains illuminated or starts flashing again after the drive, it suggests one of two things: either the tire pressure has dropped again due to a slow leak, or one of the sensor batteries has died. If the light stays solid, re-check your pressures with your gauge. If you find one tire is significantly lower than the others, you may have a puncture. If all pressures are perfect and the light persists, the system may require a professional diagnostic tool to identify a faulty sensor ID.
Pro Tip: Keep a log of your tire pressure maintenance; if the light returns frequently, it is a strong indicator that you have a nail or screw in the tread that needs a professional patch.
✅ Final Checklist
- All five tires (including the spare) are inflated to the specific cold PSI listed on the driver’s door jamb.
- The “SET” button was held until the TPMS light on the dash began its slow-blink pattern.
- The vehicle was driven for at least 10-20 minutes at speeds consistently above 25 mph.
- The TPMS dashboard icon has successfully turned off and remained off for subsequent engine cycles.
Important Notes:
- Safety: Never attempt to reset the TPMS while the vehicle is in motion or on a busy roadway. Ensure you are in a safe, stationary location.
- Professional Help: If the TPMS light flashes for one minute upon startup and then remains solid, this indicates a system fault that the reset button cannot fix. In this case, visit a Lexus dealer or tire shop to scan for a dead sensor battery or a damaged sensor.
- Estimated time and cost: This procedure takes approximately 20-30 minutes of your time and is completely free if you have your own tire gauge.
