For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
This indicates that one or more of
the tires are significantly
underinflated.
A tire pressure message can
accompany the light. See
information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information label. See
more information.
This indicates that there may be a
problem with the TPMS. The light
flashes for about a minute and stays
on steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
See
information.
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
for more
have the vehicle serviced.

The oil pressure 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.
