NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
If the ignition is switched on, an acoustic warning sounds when low tire pressure is detected. If a
system malfunction is detected, no acoustic warning sounds.
Driving for a longer period of time on rough roads or with a dynamic and sporty style can make
the TPMS system temporarily unavailable. The indicator light will come on, signaling a malfunction, but
will go out again once road condition or driving style change.
Tire Pressure Monitoring System and recalibration with the MFI
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.
Resetting and recalibrating the benchmark tire pressure
Resetting the tire pressures in the Multi-function Indicator (MFI) resets the benchmark tire pressure
used by the TPMS to the current tire pressure in the tires based on the circumference of the tires.
To reset the reference tire pressure, switch on the ignition. In the MFI, navigate to the Settings menu
and select Tire pressure. Store and confirm the new tire pressures.
The re-calibration must be performed each time the tire pressure in one or more tires has been
adjusted or after one or more tires has been changed, exchanged, or repaired. The new tire pressures
are stored in the system only after at least 20 minutes of normal driving.
If you have reset the benchmark tire pressure when your tires do not have the correct tire pressure,
this will prevent the TPMS from working properly. It may then give false warnings or may not give any
warning even if the tire pressure is too low.
For this reason, it is vital to make certain that all four tires are inflated to the correct pressure
when they are cold, before calibrating the system. Cold tire tires are tires that have not been driven
more than a couple of miles (kilometers) at low speed within the last 3 hours.
Recalibrate the system to reset the benchmark TPMS pressure in the following
situations:
x After installing tires on your vehicle that have recommended cold tire inflation pressures that are
different from the tires that were taken off.
x After any tire on your vehicle is removed and then remounted, even if the same tire and wheel rim
that were taken off are reinstalled (for instance, after repair).
x After any tire on your vehicle is changed and replaced by another tire, even if the replacement tire
is the same type and is inflated to the same pressure as the tire it replaced.
x After adjusting the tire pressure of any tire on the vehicle to its correct cold tire inflation pressure,
either by putting air in one or more tires or by letting air out. Do this even though air was only added
(or let out) to bring the tire to the inflation pressure it should have had all along.
x After rotating the front and rear wheels
x After mounting the compact spare tire.
WARNING
Incorrect calibration can cause the TPMS to give false warnings or to give no warning despite
dangerously low tire pressures. Make certain the tire inflation pressure of all tires is correct
before calibrating the system.
