Tire Pressure Monitoring System (TPMS)
Introduction
The Tire Pressure Monitoring System
(TPMS) warns the driver if tire pressures
are too low.
The following Tire Pressure Monitoring Systems (TPMS) are available for this vehicle:
Tire Pressure Monitoring System
Monitors various parameters, including rolling circumference, of all four tires using ABS sensors (indirect measurements) while the vehicle is in motion.
The reference pressure for the Tire Pressure Monitoring System is the recommended tire pressure for the tires installed at the factory when the tires are cold at
maximum load. The reference pressure corresponds to the details on the tire pressure label ⇒ Tire pressure.
If the tire pressure has been correctly adjusted on all four tires, the Tire Pressure Monitoring System must be re-calibrated ⇒ Tire Pressure Monitoring System. Th
adapts the reference pressure to the current tire pressure.
The Tire Pressure Monitoring System
may not react at first or may not react at all when you are driving in a sporty manner, or on snow-covered or unpaved
roads, when you are driving with snow chains, or in certain other situations. A change in the tread circumference of a tire is signaled by the Tire Pressure Monitoring
System indicator in the instrument cluster (telltale).
The tire pressure recommended for the tires originally installed on the vehicle is on a sticker on the driver door jamb.
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 pressu
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 under-inflated. 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 under-inflated 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 continuousl
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 th
TPMS to continue to function properly.
WARNING
The intelligent technology of the Tire Pressure Monitoring System (TPMS) cannot overcome the natural laws of physics and it can only operate within the limits
of the system. Handling wheels and tires incorrectly can result in a sudden loss of tire pressure, tread separation, and ruptured tires.
Check the tire pressure regularly and always maintain the specified values ⇒ Tire pressure. If the tire pressure is too low, the tire can heat up so much
that the tread separates or the tire ruptures.
Always inflate the tires to the correct tire pressure when the tires are cold according to the tire inflation pressure label ⇒ Tire pressure.
Check the tire pressure regularly when the tires are cold. If necessary, adjust the tire pressure when the tires are cold so that it is suitable for the tires
installed on your vehicle ⇒ Tire pressure.
Check the tires regularly for signs of wear or damage.
Never exceed the maximum permissible speed and tire load specified for the tires fitted to your vehicle.
WARNING
Different tire pressures or low tire pressure can cause tire damage, tire failure, loss of vehicle control, crashes, serious injuries, and death.
If the
warning light turns on, stop the vehicle immediately and check all of the tires ⇒ Tire pressure.
Different tire pressures or low tire pressure can increase tire wear, decrease vehicle stability, and increase braking distance.
The driver is responsible for maintaining the correct tire pressure in all tires on the vehicle. The recommended tire pressure can be found on a label
⇒ Tire pressure.
