Malfunction Telltale
Your vehicle has also been equipped with a TPMS
malfunction telltale to show when the system is not
operating correctly. The TPMS malfunction telltale is
combined with the tyre pressure telltale.
When the system detects a malfunction, the telltale will
flash for approximately one minute and then stay ON.
This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction telltale is ON, the system may
not be able to detect or send tyre pressure as intended.
TPMS malfunctions can occur for a variety of reasons,
including the installation of replacement or alternate
tyres or wheels on the vehicle that prevent the TPMS
from operating correctly.
Always check the TPMS malfunction telltale after
replacing one or more tyres or wheels on your vehicle
to make sure that the replacement or alternate tyres
and wheels allow the TPMS to continue to function
correctly.
Operation
When a tyre pressure warning is detected
reduce the vehicle speed to an appropriate safe
level and stop at the first safe and convenient place
to inspect the tyre(s).
At each ignition ON there is a short delay before tyre
pressures are received, from the wheel and tyre
transmitters, and shown in the message centre (right).
If the tyre telltale symbol comes ON while driving,
reduce speed to 48 km/h and stop in safe place as soon
as possible. Check the status of the tyre(s) in the
message centre (right):
