Tyre Pressure Monitor; Operation - Cadillac XT5 2017 Owner's Manual

268 VEHICLE CARE
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tyre
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tyres or
wheels on the vehicle that prevent the
TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tyres or wheels on your vehicle to
ensure that the replacement or
alternate tyres and wheels allow the
TPMS to continue to function
properly.
See Tyre Pressure Monitor Operation
0 268 for additional information.

Tyre Pressure Monitor

Operation

This vehicle may have a Tyre Pressure
Monitor System (TPMS). The TPMS is
designed to warn the driver when a
low tyre pressure condition exists.
TPMS sensors are mounted onto each
tyre and wheel assembly, excluding
the spare tyre and wheel assembly.
The TPMS sensors monitor the air
pressure in the tyres and transmits
the tyre pressure readings to a
receiver located in the vehicle.
When a low tyre pressure condition is
detected, the TPMS illuminates the
low tyre pressure warning light on the
instrument cluster. If the warning
light comes on, stop as soon as
possible and inflate the tyres to the
recommended pressure shown on the
Tyre and Loading Information label.
See Vehicle Load Limits 0 177.
A message to check the pressure in a
specific tyre displays in the Driver
Information Centre (DIC). The low tyre
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tyres are
inflated to the correct inflation
pressure. Using the DIC, tyre pressure
levels can be viewed. For additional
information and details about the DIC
operation and displays see Driver
Information Centre (DIC) 0 129.
The low tyre pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the air
pressure is getting low and needs to
be inflated to the proper pressure.
A Tyre and Loading Information label,
attached to your vehicle, shows the
size of the original equipment tyres
and the correct inflation pressure for
the tyres when they are cold. See
Vehicle Load Limits 0 177 for an
example of the Tyre and Loading
Information label and its location.
Also see Tyre Pressure 0 265.
The TPMS can warn about a low tyre
pressure condition but it does not
replace normal tyre maintenance.

Rotation 0 271, and Tyres 0 263.
