Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating. If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.

.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message come on
and stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a
new tire/wheel position after rotating
the vehicle’ s tires or replacing one
or more of the TPMS sensors.
Also, the TPMS sensor matching
process should be performed after
replacing a spare tire with a road
tire containing the TPMS sensor. The malfunction light and the DIC
message should go off at the next
ignition cycle. The sensors are
matched to the tire/wheel positions,
using a TPMS relearn tool, in the
following order: driver side front tire,
passenger side front tire, passenger
side rear tire, and driver side rear.
See your dealer for service or to
purchase a relearn tool.
There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off. 3. Press the Remote Keyless
Entry (RKE) transmitter's LOCK
and UNLOCK buttons at the
same time for approximately
five seconds. The horn sounds
twice to signal the receiver is
in relearn mode and TIRE
LEARNING ACTIVE message
displays on the DIC screen.
If the vehicle does not have
RKE, press the Driver
Information Center (DIC) vehicle
information button until the
PRESSVTO RELEARN TIRE
POSITIONS message displays.
The horn sounds twice to signal
the receiver is in relearn mode
and TIRE LEARNING ACTIVE
message displays on the DIC
screen.

Black plate (68,1)Chevrolet Silverado Owner Manual - 2012
10-68 Vehicle Care
If the vehicle does not have RKE
or DIC buttons, press the trip
odometer reset stem located on
the instrument panel cluster until
the PRESS
VTO RELEARN
TIRE POSITIONS message
displays. The horn sounds twice
to signal the receiver is in
relearn mode and TIRE
LEARNING ACTIVE message
displays on the DIC screen.
4. Start with the driver side front tire.
5. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position. 6. Proceed to the passenger side
front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure
in Step 5. The horn sounds
two times to indicate the sensor
identification code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire
and Loading Information label.
Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is
cracked, cut, or snagged
deep enough to show cord or
fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot
be repaired well because of
the size or location of the
damage.

properly maintained. If equipment
or software is added, connected,
or modified, OnStar service may
not work. Other problems beyond
OnStar ’s control may prevent
service such as hills, tall buildings,
tunnels, weather, electrical system
design and architecture of the
vehicle, damage to the vehicle in a
crash, or wireless phone network
congestion or jamming. See
Radio Frequency Statement on
page 13‑21 for information
regarding Part 15 of the Federal

.Obstruction of the GPS can
occur in a large city with tall
buildings; in parking garages;
around airports; in tunnels,
underpasses, or parking
garages; or in an area with very
dense trees. If GPS signals are
not available, the OnStar system
should still operate to call
OnStar. However, OnStar could
have difficulty identifying the
exact location.
.In emergency situations, OnStar
can use the last stored GPS
location to send to emergency
responders.
.A temporary loss of GPS can
cause loss of the ability to send
a Turn-by-Turn Navigation route.
The Advisor may give a verbal
route or may ask for a call back
after the vehicle is driven into an
open area.
