A DIC warning message to check
the pressure in a specific tire is also
shown on the DIC display screen.
The low tire pressure warning light
and the DIC warning message come
at each ignition cycle until the tires
are inflated to the correct inflation
pressure.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
could be an early indicator that the
air pressure in the tire(s) are getting
low and need to be inflated to the
proper pressure.
The Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for the
tires when they are cold. See

spare tire does not have a
TPMS sensor. The malfunction
