Dodge Charger: AUXILIARY DRIVING SYSTEMS / Tire Pressure Monitoring System (TPMS)

Dodge Charger 2011-2022 Owner's Manual / SAFETY / AUXILIARY DRIVING SYSTEMS / Tire Pressure Monitoring System (TPMS)

The Tire Pressure Monitoring System (TPMS) will warn the driver of a low tire pressure based on the vehicle recommended cold placard pressure.

The tire pressure will vary with temperature by about 1 psi (7 kPa) for every 12°F (6.5°C). This means that when the outside temperature decreases, the tire pressure will decrease.

Tire pressure should always be set based on cold inflation tire pressure. This is defined as the tire pressure after the vehicle has not been driven for at least three hours, or driven less than 1 mile (1.6 km) after a three hour period. The cold tire inflation pressure must not exceed the maximum inflation pressure molded into the tire sidewall. The tire pressure will also increase as the vehicle is driven — this is normal and there should be no adjustment for this increased pressure.

The TPMS will warn the driver of a low tire pressure if the tire pressure falls below the low-pressure warning limit for any reason, including low temperature effects and natural pressure loss through the tire.

The TPMS will continue to warn the driver of low tire pressure as long as the condition exists, and will not turn off until the tire pressure is at or above the recommended cold placard pressure. Once the low tire pressure warning (TPMS Warning Light) illuminates, you must increase the tire pressure to the recommended cold placard pressure in order for the TPMS Warning Light to turn off. The system will automatically update and the TPMS Warning Light will turn off once the system receives the updated tire pressures. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) in order for the TPMS to receive this information.

NOTE:

When filling warm tires, the tire pressure may need to be increased up to an additional 4 psi (28 kPa) above the recommended cold placard pressure in order to turn the TPMS Warning Light off.

For example, your vehicle may have a recommended cold (parked for more than three hours) placard pressure of 30 psi (207 kPa). If the ambient temperature is 68°F (20°C) and the measured tire pressure is 27 psi (186 kPa), a temperature drop to 20°F (-7°C) will decrease the tire pressure to approximately 23 psi (158 kPa). This tire pressure is sufficiently low enough to turn on the TPMS Warning Light. Driving the vehicle may cause the tire pressure to rise to approximately 27 psi (186 kPa), but the TPMS Warning Light will still be on. In this situation, the TPMS Warning Light will turn off only after the tires are inflated to the vehicle’s recommended cold placard pressure value.

CAUTION!

  • The TPMS has been optimized for the orig- inal equipment tires and wheels. TPMS pressures and warning have been estab- lished 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. The TPMS sensor is not designed for use on after- market wheels and may contribute to a poor overall system performance or sensor damage. Customers are encouraged to use OEM wheels to assure proper TPMS feature operation.
  • Using aftermarket tire sealants may cause the Tire Pressure Monitoring System (TPMS) sensor to become inoperable. After using an aftermarket tire sealant it is recommended that you take your vehicle to your authorized dealer to have your sensor function checked.
  • After inspecting or adjusting the tire pres- sure always reinstall the valve stem cap. This will prevent moisture and dirt from entering the valve stem, which could damage the TPMS sensor.

NOTE:

  • The TPMS is not intended to replace normal tire care and maintenance or to provide warning of a tire failure or condition.
  • The TPMS should not be used as a tire pres- sure gauge while adjusting your tire pressure.
  • Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability.
  • The TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsi- bility to maintain correct tire pressure using an accurate tire pressure gauge, even if underin- flation has not reached the level to trigger illu- mination of the TPMS Warning Light.
  • Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire Ú page 341.

Premium System

The Tire Pressure Monitoring System (TPMS) 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.

NOTE:

It is particularly important for you to check the tire pressure in all of the tires on your vehicle monthly and to maintain the proper pressure. The TPMS consists of the following components:

  • Receiver module
  • Four Tire Pressure Monitoring System sensors
  • Various Tire Pressure Monitoring System messages, which display in the instrument cluster
  • Tire Pressure Monitoring System Warning Light

    Forward Collision Warning (FCW) With Mitigation Operation

    FCW with Mitigation provides the driver with audible warnings, visual warnings (within the instrument cluster display), and may apply haptic warning in the form of a a brake jerk, to warn the driver when it detects a potential frontal collision...

    Tire Pressure Monitoring Low Pressure Warnings

    The Tire Pressure Monitoring System (TPMS) Warning Light will illuminate in the instrument cluster and a chime will sound when tire pressure is low in one or more of the four active road tires...
