Land Rover Defender: Tire Pressure Monitoring System (TPMS)

TIRE PRESSURE MONITORING SYSTEM (TPMS)

The Tire Pressure Monitoring System (TPMS) provides a low pressure warning and does not re-inflate the tires. Tire pressures should be checked regularly, using an accurate pressure gauge when the tires are cold. Failure to do so could result in an accident, leading to serious injury or death.

The TPMS cannot register damage to a tire. Regularly check the condition of the tires, especially if the vehicle is driven off-road. Failure to do so could result in an accident, leading to serious injury or death.

When inflating tires, care should be taken to avoid bending or damaging the TPMS valves. Always make sure that the inflation head is correctly aligned to the valve stem.

To avoid damage to the TPMS valves, it is recommended not to use rigid tire inflation wands. Using rigid inflation wands increases the risk of excess leverage and sideways pressure on the valve.

The tire pressure warning lamp illuminates when one or more of the tires are significantly under-inflated. Stop and check the tires as soon as possible. Inflate the tires to the recommended inflation pressures for the vehicle's loading condition.

The TPMS constantly monitors the tire pressure in each road wheel. The spare wheel tire pressure is not monitored.

To confirm if TPMS is fitted to the vehicle: Switch on the vehicle's ignition and check for the presence of a TPMS lamp in the instrument panel. Vehicles with a TPMS lamp have TPMS.

TPMS lamp.

Note: A special service kit is required when changing a tire fitted with a TPMS valve.

Note: Non-approved accessories may interfere with the TPMS. If this occurs, the instrument panel displays the message Tire pressure monitoring system fault.

Note: Different types of tires may affect the performance of the TPMS. Always replace the tires in accordance with recommendations.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly underinflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS 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 illumination of the TPMS low tire pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly.

The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists.

When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.

Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly.
