2012 CHEVROLET IMPALA tire pressure 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.
Fuel E85 (85% Ethanol)
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
See Fuel E85 (85% Ethanol) on
page 9‑39. For all other vehicles,
use only the unleaded gasoline
described under Recommended
Fuel on page 9‑37.

the CHANGE ENGINE OIL SOON
message will appear on the display.
SeeEngine Oil Messages on
page 5‑31. You should change the
oil as soon as possible. See Engine
Oil on page 10‑7. In addition to the
engine oil life system monitoring the
oil life, additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Maintenance Schedule on
page 11‑3 for more information.
Remember, you must reset the OIL
LIFE yourself after each oil change.
It will not reset itself. Also, be
careful not to reset the OIL LIFE
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
engine oil life system, see Engine
Oil Life System on page 10‑10. Units
Press the vehicle information

Tire Messages
SERVICE TIRE MONITOR
SYSTEM
On vehicles with the Tire Pressure
Monitor System (TPMS), this
message displays if a part on the
TPMS is not working properly. The
tire pressure light also flashes and
then remains on during the same
ignition cycle. SeeTire Pressure
Light on page 5‑22. Several
conditions may cause this message
to appear. See Tire Pressure
Monitor Operation on page 10‑44 for
more information. If the warning
comes on and stays on, there may
be a problem with the TPMS. See
your dealer.
TIRE LEARNING ACTIVE
On vehicles with the Tire Pressure
Monitor System (TPMS), this
message displays when the TPMS
is re-learning the tire positions on
your vehicle. The tire positions must
be re-learned after rotating the tires
or after replacing a tire or sensor.
See Tire Inspection on page 10‑47,
Tire Rotation on page 10‑47, Tire
Pressure Monitor System on
page 10‑43, and Tire Pressure on
page 10‑41 for more information.
TIRE LOW ADD AIR TO TIRE
On vehicles with the Tire Pressure
Monitor System (TPMS), this
message displays when the
pressure in one or more of the
vehicle's tires is low. This message
also displays LEFT FRT (left front),
RIGHT FRT (right front), LEFT RR
(left rear), or RIGHT RR (right rear)
to indicate the location of the low
tire. The low tire pressure warning light will also come on. See
Tire
Pressure Light on page 5‑22. You
can receive more than one tire
pressure message at a time. To
read the other messages that may
have been sent at the same time,
press the set/reset button. If a tire
pressure message appears on the
DIC, stop as soon as you can. Have
the tire pressures checked and set
to those shown on the Tire and
Loading Information label. See Tires
on page 10‑35, Vehicle Load Limits
on page 9‑11, and Tire Pressure on
page 10‑41. The DIC also shows
the tire pressure values. See Driver
Information Center (DIC) on
page 5‑24.

Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure on page 10‑41
andVehicle Load Limits on
page 9‑11.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑44.
Check that all wheel nuts are
properly tightened. See “Wheel
Nut Torque” underCapacities
and Specifications on
page 12‑2.{WARNING
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for New
Tires
Factors such as maintenance,
temperatures, driving speeds,
vehicle loading, and road conditions
affect the wear rate of the tires.
Treadwear indicators are one way to
tell when it is time for new tires.
Treadwear indicators appear when
the tires have only 1.6 mm (1/16 in)
or less of tread remaining. See Tire
Inspection on page 10‑47 andTire
Rotation on page 10‑47 for more
information.
