Problem | Possible causes/consequences and •► Solutions |
USA only:
The yellow tire pressure monitor warning lamp (pressure loss/ malfunction) is lit.
Canada only:
The yellow tire pressure monitor warning lamp (pressure loss) is lit.
Risk of accident
The tire pressure monitor has detected a loss of pressure in at
least one of the tires.
•► Stop the vehicle without making any sudden steering or braking maneuvers. Pay attention to the traffic conditions as you do so.
•► Observe the additional display messages in the multifunction display.
•► Check the tire pressure. If necessary, correct the tire pressure.
•► If necessary, change a wheel
USA only:
The yellow tire pressure monitor warning lamp (pressure loss/ malfunction) flashes for 60 seconds and then remains lit.
The tire pressure monitor is faulty.
•► Observe the additional display messages in the multifunction display.
•► Visit a qualified specialist workshop
WARNING
Each tire, including the spare (if provided), should be checked at least every
two weeks when
cold and inflated to the pressure recommended by the vehicle manufacturer on the
Tire and
Loading Information placard on the driver's door B-pillar or, if available, the
tire pressure label
on the inside of the fuel filler flap. If your vehicle has tires of a different
size than the size indicated
on the Tire and Loading Information placard or the tire pressure label, you
should determine the
proper tire 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 are 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.
Underinflation 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 underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.
USA only:
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 1 minute and then remain continuously illuminated. This sequence will be repeated every time the vehicle is started 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 incompatible 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.
