Tire Monitoring System: Description and Operation
TIRE PRESSURE MONITOR SYSTEM - IF EQUIPPED
Tire Pressure Monitoring - Base System
The Tire Pressure Monitor System (TPM) system uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels (EXCLUDING THE SPARE TIRE). Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the Receiver Module.
NOTE: It is particularly important, for you to check the tire pressure in all of your tires regularly and to maintain the proper pressure.
The Tire Pressure Monitoring Indicator Lamp will illuminate in the instrument cluster, and an audible chime will be activated when one or more tire pressures is low. The Tire Pressure Monitoring Indicator Lamp will flash on and off for ten seconds when a system fault is detected. The flash cycle will repeat every ten minutes or until the fault condition is removed and reset.
The Tire Pressure Monitoring System consists of the following components;
- Receiver Module
- 4 Wheel Sensors
- Amber Colored Tire Pressure Monitoring Indicator Lamp
The system will consist of tire pressure monitoring sensors attached to each wheel through the valve stem mounting hole, a central receiver module and an amber colored indicator Lamp. A sensor is located in the spare wheel if the vehicle is equipped with a matching full size spare wheel and tire assembly.
NOTE: For vehicles with optional wheel/tire sizes and significantly different tire placard pressures, the placard pressure value and the low-pressure threshold value is re-programmable at your authorized dealer to accommodate the customer selected wheel/tire combinations recommended by DaimlerChrysler.
CAUTION! The TPM system has been optimized for the original equipment tires and wheels. TPM system pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use tire sealant from a can, or balance beads if your vehicle is equipped with a TPM system, as damage to the sensors may result.
CAUTION! After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the wheel rim sensor.
NOTE:
- The TPM system can inform the driver of a low tire pressure condition.
- The TPM system is not intended to replace normal tire care and maintenance, nor to provide warning of a tire failure or condition.
- The TPM system should not be used as a tire pressure gauge while adjusting your tire pressure.
Tire Pressure Monitoring - Premium System
The Tire Pressure Monitor System (TPM) system uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors mounted to each wheel as part of the valve stem transmit tire pressure readings to the Receiver Module. The wheel sensors monitor tire pressure, and status for all four active road tires and the spare tire. The spare tire pressure is monitored, but not displayed.
NOTE: It is particularly important, for you to check the tire pressure in all of your tires regularly and to maintain the proper pressure.
The Tire Pressure Monitoring Indicator Lamp will illuminate in the instrument cluster, and an audible chime will be activated when one or more tire pressures is low. The Tire Pressure Monitoring Indicator Lamp will flash on and off for ten seconds when a system fault is detected. The flash cycle will repeat every ten minutes or until the fault condition is removed and reset.
The Tire Pressure Monitoring System consists of the following components:
- Receiver Module
- 4 Wheel Sensors
- 4 Wheel Sensor Trigger Modules
- Tire Pressure Monitoring System Display Messages in the EVIC
- Amber Colored Tire Pressure Monitoring Indicator Lamp
The system consists of tire pressure monitoring sensors attached to each wheel through the valve stem mounting hole, a central receiver module, Wheel Sensor Trigger Modules mounted in three of the four wheel wells, various Tire Pressure Monitoring System Display Messages in the EVIC, and an amber colored Indicator Lamp. A sensor shall be installed in the spare wheel if the vehicle is equipped with a matching full size spare wheel and tire assembly.
NOTE: For vehicles with optional wheel/tire sizes and significantly different tire placard pressures, the placard pressure value and the low-pressure threshold value is reprogrammable at your authorized dealer to accommodate the customer selected wheel/tire combinations recommended by DaimlerChrysler.
The following "warnings" will cause a text message to be displayed, an audible chime to sound and the tire pressure Indicator Lamp to illuminate. The audible chime will occur once every ignition cycle for each "warning" detected. The tire pressure Indicator Lamp will illuminate continuously (solid) and shall remain illuminated until the warning condition is removed/reset.
NOTE: The Indicator Lamp will only illuminate for the four active road tires. A low spare tire pressure will not cause the indicator Lamp to illuminate.
When the appropriate conditions exist, the Electronic Vehicle Information Center (EVIC) displays the following messages.
LEFT FRONT, LEFT REAR, RIGHT FRONT, RIGHT REAR LOW PRESSURE
One or more of these messages will be displayed in the EVIC if a low tire pressure condition exists in one or more tires.
Inspect all tires for proper inflation pressure, once the proper tire pressure has been set, the TPM system warning will reset automatically when the vehicle has been driven for at least 2 minutes at or above 15 mph (24 km/h).
CHECK TPM SYSTEM
See your authorized dealer when this message appears in the EVIC. This message indicates that a system fault condition has been detected.
CAUTION! The TPM system has been optimized for the original equipment tires and wheels. TPM system pressures have been established for the tire size equipped on your vehicle. Undesirable system operation or sensor damage may result when using replacement equipment that is not of the same size, type, and/or style. After-market wheels can cause sensor damage. Do not use tire sealant from a can, or balance beads if your vehicle is equipped with a TPM system, as damage to the sensors may result.
CAUTION! After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the wheel rim sensor.
NOTE:
- The TPM system can inform the driver of a low tire pressure condition.
- The TPM system is not intended to replace normal tire care and maintenance, nor to provide warning of a tire failure or condition.
- The TPM system should not be used as a tire pressure gauge while adjusting your tire pressure.
