• Ultra-Clear LCD Display: Large, high-definition screen with automatic brightness adjustment for clear visibility day and night.
• Dual Charging: Features solar and USB Type-C charging options for continuous power.
• Effortless Installation: External sensors can be screwed onto tire valves in minutes, requiring no wiring or tire removal.
• Universal Fit: Compatible with RVs, SUVs, sedans, MPVs, and pickup trucks.
• All-Weather Durability: Engineered to withstand dust, water, wind, and snow (IP68 rated).

2. What's in the Box

Please check the package contents to ensure all items are present:

• 1 x TPMS Monitor
• 4 x TPMS Sensors (labeled FR, FL, RR, RL)
• 1 x Double-Sided Adhesive Tape
• 1 x Type-C USB Charging Cable
• 1 x Screwdriver
• 4 x Metal Valve Gaskets (Anti-theft nuts)

3. Setup and Installation

The LETOURWM TPMS is designed for quick and easy installation without the need for professional assistance or tire disassembly.

Monitor Placement:

Place the TPMS monitor on your vehicle's dashboard where it has clear visibility and can receive sunlight for solar charging. Use the provided double-sided adhesive tape to secure it.

Sensor Installation:

1. Unscrew the original valve cap from each tire.
2. Screw on the anti-theft nut (metal valve gasket) onto the valve stem.
3. Screw the corresponding TPMS sensor (FR for Front Right, FL for Front Left, RR for Rear Right, RL for Rear Left) onto the valve stem. Ensure it is tightened securely.
4. Use the provided screwdriver to tighten the anti-theft nut against the sensor to prevent unauthorized removal.

The sensors are pre-paired with the monitor. If a sensor needs to be re-matched or replaced, refer to the 'Matching Sensors' section under Operating Instructions.

4. Operating Instructions

The TPMS monitor automatically turns on when the car starts and turns off when the car is stationary, conserving battery life. It provides real-time tire pressure and temperature readings on its LCD screen.

Display Information:

• Pressure Value: Displays current tire pressure for each wheel.
• Temperature Value: Shows current tire temperature for each wheel.
• Battery Level: Indicates the monitor's battery status.
• Solar Charging Indicator: Lights up when the monitor is charging via solar power.
• Tire Position Icons: Clearly shows which tire's data is being displayed.

Alarm Modes:

The system will provide visual and voice alerts for the following conditions:

• Low Pressure Warning
• High Pressure Warning
• High Temperature Warning
• Rapid/Slow Leakage Warning
• Sensor Failure Warning
• Low Battery Warning

5. Settings and Customization

You can customize various settings on your TPMS monitor, including pressure units, temperature units, and alarm thresholds.

Setting the Pressure/Temperature Display Unit and Alarm Values:

Refer to the video below for a visual guide on how to set the pressure and temperature display units, as well as low and high pressure alarm values.

1. Enter Setting System: Hold the "SET" button for 3 seconds. The Bar/PSI interface will flash.
2. Navigate Settings: Press the "SET" button to cycle through different settings (pressure unit, temperature unit, low pressure alarm, high pressure alarm, etc.).
3. Adjust Value: Use the "+" or "-" buttons to change the flashing value or unit.
4. Save Setting: Hold the "SET" button for 3 seconds to save the current setting and exit the setting mode.

Customizing Individual Tire Pressure/Temperature Settings:

This section details how to adjust individual tire pressure and temperature alarm thresholds.

1. Enter Setting Mode: Press and hold the 'M' button for 3 seconds. The Bar/PSI interface will flash, indicating entry into the setting mode. Use left/right keys to select the unit. Press 'M' to switch to the next temperature unit.
2. Adjust Values: When a number on the display is flashing, use the left and right keys to adjust it.
3. Set Tire Values: After determining what you want to set, press the 'M' button. Use left and right keys to choose the value. Press 'M' again to save.
4. Save All Settings: After setting all values, press and hold the 'M' button for 3 seconds to save all changes.

Matching Sensors (if needed):

If a sensor is not displaying data or needs to be re-matched:

1. Restart the receiver.
2. Adjust the display to match mode by pressing the right button 8 times in a row.
3. If two bars are blinking, you are setting up data for that tire.
4. Press the right button to select the tire that needs to be re-matched.
5. Screw the sensor onto the tire. The data should then display.
6. Once tire pressure data is displayed, press and hold the 'M' button to save the data.
7. If there is still no display, unscrew the receiver, wait 10 seconds, and repeat steps 1-5.

7. Troubleshooting

If you encounter any issues with your LETOURWM TPMS, please refer to the following common troubleshooting tips:

• No Display/Blank Screen: Ensure the monitor is charged (via solar or USB-C). Check if the monitor automatically turns on when the vehicle starts.
• No Tire Data: Verify that sensors are correctly installed and tightened. If a specific sensor is not reporting, try re-matching it as described in the 'Matching Sensors' section. Ensure the vehicle is moving for a few minutes to activate sensors.
• Inaccurate Readings: Confirm that the correct pressure unit (PSI/BAR) is selected in the settings. Ensure sensors are securely attached and not leaking air.
• Alarm Constantly On: Check the tire pressure and temperature against the set alarm thresholds. Adjust thresholds if necessary, or inflate/deflate tires to recommended levels.
• Weak Signal: Ensure there are no major obstructions between the sensors and the monitor. For larger vehicles, signal repeaters might be necessary (not included).
• Sensor Battery Low: Replace sensor batteries if indicated. The external sensors typically have a battery life of up to 2 years.

For persistent issues, please contact customer support.
