2012 CHEVROLET IMPALA TPMS reset

Black plate (18,1)Chevrolet Impala Owner Manual - 2012
1-18 In Brief
During cooler conditions, the low tire
pressure warning light may appear
when the vehicle is first started and
then turn off. This may be an early
indicator that the tire pressures are
getting low and the tires need to be
inflated to the proper pressure.
The TPMS does not replace normal
monthly tire maintenance. It is the
driver’s responsibility to maintain
correct tire pressures.
See Tire Pressure Monitor System
on page 10‑43.
Engine Oil Life System
The engine oil life system calculates
engine oil life based on vehicle use
and displays a DIC message when
it is necessary to change the engine
oil and filter. The oil life system
should be reset to 100% only
following an oil change. Resetting the Oil Life System
1. Display OIL LIFE REMAINING
on the DIC.
2. Press and hold the SET/RESET button on the DIC for more than
five seconds. The oil life will
change to 100%.
See Engine Oil Life System on
page 10‑10.
