Introduction

At a Glance
We have developed a simple and easy-to-install Tire Pressure Monitoring
System to meet the growing demand for a simple external kit to help upgrade
your vehicle’s tire safety.
Available as a self-installable external sensor kit, nonda’s Smart Tire Safety
Monitor features a USB-powered receiver with 4 external sensors that transmit
data via Bluetooth directly to the ZUS app. Showing the tire pressure of all 4
tires in real time, the monitor can quickly detect punctures and/or excess
temperature, giving both a visual and audible warning to alert the driver of
possible tire failure. While the receiver utilizes a USB port, it does come with a
USB output port for charging your mobile devices or GPS unit. As a result, you
never lose a USB port.

App Download, Receiver Connection & Sensor Installation
Connect the receiver to a USB car charger. Pair the receiver with your mobile
device before installing the sensors.
The sensor caps are labelled with Front Right (FR), Front Left (FL), Rear Right
(RR), and Rear Left (RL). Please install each sensor onto the respective tire.
Congratulations!
Sensor installation is complete! However, if you are worried about the sensors
being stolen or air leaking, please follow the optional steps on the next page.
Search “ZUS” on the
App Store or Google Play
and download the app on
your mobile phone.
Plug the receiver into
a USB port & start the
engine to power it up.
Make sure you see the
white lights blinking.
Open the ZUS app
and turn on your
device’s Bluetooth.
Click "add a device" and
place your phone next
to receiver to pair.
Unscrew the valve
cap and put it into the
installation kit bag, and
keep it in your glove
box for future use
Screw on the
anti-theft nut to the
end of the valve stem. If
your tires have a long
valve stem, see P5 for
more info.
Screw the sensor
clockwise onto the valve
stem until it is tight.

Troubleshooting Procedures
If you are concerned about sensors being
stolen, please tighten the anti-theft nut
counterclockwise to the sensor.
If you are concerned that there may be an air
leak, spray soapy water around the sensor and
check whether there are bubbles coming out.
If that is the case then please tighten the sensor.
Configure the alarm settings as specified on your
vehicle. Recommended cold inflation pressure is
displayed on the owner's manual and on the
placard (or sticker) placed on the vehicle’s door,
pillar, glove box, or fuel filler flap.
Should any of the sensors fail to show results, please note the following:
1. The receiver may not be properly connected. Please make sure the receiver
is plugged into a USB charger and the white Bluetooth LED are blinking or
solid.
2. Drive your vehicle above 14 mph (22 kph) for about 10 mins.
3. If any of the 4 sensors fail to show readings on the ZUS app, try installing
the sensor on another tire and see if any readings appear. If not, please
contact [email protected] for further support.
If the above toubleshooting procedures don’t work, please follow the
aforementioned sensor installation steps to reinstall the sensor again.
If it still does not work, please contact our customer service at [email protected].

nonda Smart Tire Safety Monitor is for use with metal tire valve stems
only. Installation of the Tire Sensors on non-metal tire valve stems may
cause tire and/or tire valve stem damage which could result in serious
personal injury or death.
Use of the Smart Tire Safety Monitor is not a substitute for proper tire
maintenance, and it is the driver's responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger the
low tire pressure alert. Failure to maintain proper tire pressure can
result in loss of control of the vehicle, which may lead to serious
personal injury or death.
Keep out of the reach of children.
It is highly recommended the sensors be removed before the car is sent
to an automatic car wash.
To avoid sensor corrosion, please re-install the sensors every two
months.
Sensors monitor tire temperature (Celsius) and pressure (0~50 psi).
Sensor signal covers 19.6 ft (5.9 m). COMPATIBLE WITH MOST CARS
EXCEPT FOR RVs, TRAILERS, TRUCKS, OR MOTORHOMES.
