Not recommended for installation on any type of trailer.
May not work on certain Porsche 911 Turbo wheels that require an 8mm valve.
Hella's TC-400 Tire Pressure Monitor System allows for permanent monitoring of tire pressure and temperature in vehicles not
originally equipped with a tire pressure monitoring system. Sensors on the tire valves transmit pressure and temperature via
radio signal to the central unit, which in turn forwards this data to the display mounted inside the vehicle.

The system includes one LCD display, one control unit w/antenna, four tire valve sensors and installation instructions CD and
hardware. Once installed, the system can monitor up to seven tires. Extra sensors are available.

Alerts
Display changes color when alert is given
Orange display: 50% pressure loss
Temperature alert (185ºF +)
Overpressure alert (50% overpressure)
All alerts and settings can be customized
Upon ignition, the system will immediately display a warning if an alert is present. Otherwise, the maximum time between a
sensed change in temperature or pressure and notification via an alert to the display is 3 seconds. In case of alert, the system
transmits every 0.9 seconds. When normal temperatures and pressures are found, the system will transmit settings every 4
seconds.

Additional Features
Adjustable display background color customizable to match vehicle's instrument lighting (blue, red, green, orange, light orange,
white, light blue)
Large symbols depict tire condition and position
Simple, two button display
Not recommended for use with applications requiring a base pressure of 70psi or higher
Tested at speeds of up to 245 mph
Guaranteed at speeds of up to 155 mph while at 185ºF
Sensor battery life approximately 7-10 years
NOTE: Each sensor is labeled LF, LR, RF, RR, but the system can be programmed to new locations after tire rotation, etc.
Sensors cannot be more than 32 feet away from control unit's antenna.
This product is not recommended for use on vehicles with aftermarket window tinting.
Not recommended for installation on any type of trailer.
May not work on certain Porsche 911 Turbo wheels that require an 8mm valve.
HELLA TIRE PRESSURE MONITOR
We all know how important tire pressure is in an
EV, underinflated tires could cost you up to 10% of
your range! Here is an easy way to keep an eye on
tire pressure everytime you drive.

ToughMeter Panel Meters
The Tough Meter series of analog panel meters is designed to operate in harsh
environments. The 2 1/2" and 3 1/2" size meters have gasket sealed bezels, terminals
and zero regulators to ensure dust and moisture protection. The meter mechanisms
have a long history of lasting durability and performance within specifications. Pivot &
jewel suspension.   (note: these are not backlit)

BIG LOOK METERSThese meters feature extra-wide scales, big bold numerals above the scale and divisions
for unobstructed reading. Tapered needle-sharp pointers and shadow-free acrylic covers help to pinpoint
values. Available in taut band and pivot and jewel types. Gasket sealer gives New Big Look dust and moisture
resistant design. (note:these are not backlit)
Horizon Line Panel Meters
These meters possess the same precision qualities as New Big Look. In addition, Horizon Line panel meters
can be front or rear mounted on panel.    (note:these are not backlit)
