2009 CHEVROLET SILVERADO engine

Vehicles with P265/70R17 or P275/55R20 size tires
require ination pressure adjustment when driving the
vehicle at speeds of 100 mph (160 km/h) or higher. Set
the cold tire ination pressure to 3 psi (20 kPa) above
the recommended cold tire pressure shown on the
Tire and Loading Information label.
When you end this high-speed driving, return the tires
to the cold ination pressure shown on the Tire and
Loading Information label. SeeLoading the Vehicle on
page 4-32andInflation - Tire Pressure on page 5-73.
Dual Tire Operation
When the vehicle is new, or whenever a wheel, wheel bolt
or wheel nut is replaced, check the wheel nut torque after
100, 1,000 and 6,000 miles (160, 1 600 and 10 000 km)
of driving. For proper torque and wheel nut tightening
information, seeRemoving the Spare Tire and Tools on
page 5-94.The outer tire on a dual wheel setup generally wears
faster than the inner tire. Your tires will wear more evenly
and last longer if you rotate the tires periodically, see
Tire Inspection and Rotation on page 5-81. Also see
Scheduled Maintenance (Gasoline Engine) on page 6-4.
{CAUTION:
If you operate your vehicle with a tire that is badly
underinated, the tire can overheat. An overheated
tire can lose air suddenly or catch re. You or
others could be injured. Be sure all tires (including
the spare) are properly inated.
SeeInflation - Tire Pressure on page 5-73, for
information on proper tire ination.

The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch 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 ve seconds. The horn sounds twice
to signal the receiver is in relearn mode and TIRE
LEARNING ACTIVE message displays on the DIC
screen.
If your vehicle does not have RKE, press the Driver
Information Center (DIC) vehicle information button
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.
If your 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. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for ve seconds, or
until a horn chirp sounds. The horn chirp, which may
take up to 30 seconds to sound, conrms that the
sensor identication 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 identication code has been
matched to the driver side rear tire, and that 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.
11. Put the valve caps back on the valve stems.

Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle’s tires, including the spare tire, for signs of
wear or damage. SeeWhen It Is Time for New
Tires on page 5-83for more information.
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km). SeeScheduled Maintenance
(Gasoline Engine) on page 6-4.
The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This
will ensure that your vehicle continues to perform
most like it did when the tires were new.
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 5-83
andWheel Replacement on page 5-89.
If your vehicle has dual rear wheels, also seeDual
Tire Operation on page 5-75.If your vehicle has single rear wheels and the
tread design for the front tires is the same as the
rear tires, use the rotation pattern shown here
when rotating the tires.

Changing a Flat Tire
If a tire goes at, avoid further tire and wheel damage by
driving slowly to a level place. Turn on the hazard
warning ashers. SeeHazard Warning Flashers on
page 3-8.
{CAUTION:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you or
other people. You and they could be badly injured
or even killed. Find a level place to change your
tire. To help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in P (Park).
3. If you have a four-wheel-drive vehicle,
be sure the transfer case is in a drive
gear – not in N (Neutral).
CAUTION: (Continued)
CAUTION: (Continued)
4. Turn off the engine and do not restart while
the vehicle is raised.
5. Do not allow passengers to remain in the
vehicle.
To be even more certain the vehicle will not move,
put blocks at the front and rear of the tire farthest
away from the one being changed. That would be
the tire on the other side, at the opposite end of
the vehicle.
When the vehicle has a at tire (B), use the following
example as a guide to assist you in the placement
of wheel blocks (A).

Vehicle Identication
Vehicle Identication Number (VIN)
This is the legal identier for your vehicle. It appears on
a plate in the front corner of the instrument panel, on
the driver side. It can be seen through the windshield
from outside the vehicle. The VIN also appears on
the Certication/Tire and Service Parts labels and the
certicates of title and registration.
Engine Identication
The eighth character in the VIN is the engine code. This
code helps identify the vehicle’s engine, specications,
and replacement parts. See “Engine Specications”
underCapacities and Specifications on page 5-130for
your vehicle’s engine code.
Service Parts Identication Label
This label is on the inside of the glove box. It is
very helpful if you ever need to order parts. The label
has the following information:
Vehicle Identication Number (VIN)
Model designation
Paint information
Production options and special equipment
Do not remove this label from the vehicle.

Underhood Fuse Block
If your vehicle has the DURAMAX®Diesel engine, see
the DURAMAX®Diesel manual for more information.
If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
The underhood fuse block is located in the engine
compartment, on the driver side of the vehicle.
Lift the cover to access the fuse block.
Notice:Spilling liquid on any electrical components
on the vehicle may damage it. Always keep the
covers on any electrical component.
To remove fuses, hold the end of the fuse between your
thumb and index nger and pull straight out.
