Tyre Pressure Light; Engine Oil Pressure Light - Cadillac 2015 ATS Owner's Manual

5-22 Instruments and Controls

Tyre Pressure Light

For vehicles with the Tyre Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tyre pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tyres are significantly
underinflated.
A Driver Information Centre (DIC)
tyre pressure message may also
display. See Tyre Messages on
page 5-41. Stop as soon as
possible, and inflate the tyres to the
pressure value shown on the Tyre
and Loading Information label. See
Tyre Pressure on page 10-37.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See Tyre Pressure Monitor
Operation on page 10-40.

Engine Oil Pressure Light

Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required, but if
the oil level is within the operating
range and the oil pressure is still
low, have the vehicle serviced.
Always follow the maintenance
schedule for changing engine oil.
This light should come on briefly as
the engine is started. If it does not
come on, have the vehicle serviced
by your dealer.
If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer.
