How does the system work
The product comes with 4 external sensors and a cigarette-plug receiver with Bluetooth module built-in. Once the vehicle is up running, it shows in real time the current tyre pressures of all 4 tyres in PSI format on your iPhone. The audible and visual warning appears on your iPhone when a tyre pressure or temperature drops below or raises above the recommended level. All sensors come pre paired to the correct wheel position and are labelled for easy installation, simply screw each sensor onto the vehicle valve stem then lock in place with the provided locknut and tool.

Suitable vehicles
It suits vehicles such as passenger cars, 4x4s and some RVs with pressure range from 0~50psi. Some people use the system to monitor caravan during holidays, please note the ideal sensor to Bluetooth display distance is 4~ 5m and Bluetooth display to your Phone is around 5M.

Installation is easy just in four simple steps.
Step 1: Screw on and lock all 4 sensors. Note each sensor has letters on the housing that correspond to a tyre, FL = Front Left Tyre, FR = Front Right Tyre, RR = Rear Right Tyre, RL = Rear Left Tyre
Step 2: Plug in cigarette style display.
Step 3: Download Steelmate TPMS app from Apple store and install.
Step 4. Turn on ignition and your ready to go.
