9-36 Driving and Operating
Starting Procedure
1. With your foot off the acceleratorpedal, turn the ignition key to
START. When the engine starts,
let go of the key. The idle speed
will go down as your engine gets
warm. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently to allow
the oil to warm up and lubricate
all moving parts.
The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key
is turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking
for a few seconds or until the
vehicle starts. If the engine does
not start and the key is held
in START for many seconds,
cranking will be stopped after
15 seconds to prevent cranking
motor damage. To prevent gear damage, this system also
prevents cranking if the engine
is already running. Engine
cranking can be stopped by
turning the ignition switch to
the ACC/ACCESSORY or
LOCK/OFF position.
When the Low Fuel warning
lamp is on and the FUEL LEVEL
LOW message is displayed in
the Driver Information Center
(DIC), the Computer‐Controlled
Cranking System is disabled
to prevent possible vehicle
component damage. When
this happens, hold the ignition
switch in the START position
to continue engine cranking.
Notice: Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down. 2. If the engine does not start
after 5‐10 seconds, especially
in very cold weather (below
−18°C or 0°F), it could be
flooded with too much gasoline.
Try pushing the accelerator
pedal all the way to the floor
and holding it there as you hold
the key in START for up to
15 seconds. Wait at least
15 seconds between each try, to
allow the cranking motor to cool
down. When the engine starts,
let go of the key and accelerator.
If the vehicle starts briefly but
then stops again, do the same
thing. This clears the extra
gasoline from the engine. Do not
race the engine immediately
after starting it. Operate the
engine and transmission gently
until the oil warms up and
lubricates all moving parts.

Engine Oil
Checking Engine Oil
For diesel engine vehicles, see
“Engine Oil” in the Duramax Diesel
Supplement.
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the oil
must be warm and the vehicle
must be on level ground.
The engine oil dipstick handle
is a yellow loop. See Engine
Compartment Overview
on
page 10‑6for the location
of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes to drain back
into the oil pan. If this is not
done, the oil dipstick might
not show the actual level.
2. Pull out the dipstick and clean it with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the tip
down, and check the level.

Black plate (8,1)Chevrolet Silverado Owner Manual - 2011
10-8 Vehicle Care
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick,
add at least one quart/liter of the
recommended oil. This section
explains what kind of oil to use.
For engine oil crankcase capacity,
seeCapacities and Specifications
on page 12‑2.
Notice: Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
cross-hatched area that shows
the proper operating range, the
engine could be damaged. See
Engine Compartment Overview
on page 10‑6for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
What Kind of Engine Oil to Use
Look for three things:
.GM6094M
Use only an oil that meets GM
Standard GM6094M.
.SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on
an oil container show its
viscosity, or thickness.
Do not use other viscosity
oils such as SAE 20W-50.
.American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst
symbol on the container. This
symbol indicates that the oil has
been certified by the American
Petroleum Institute (API).
Notice: Use only engine oil
identified as meeting GM
Standard GM6094M and showing
the American Petroleum Institute
Certified For Gasoline Engines
starburst symbol. Failure to use
the recommended oil can result
in engine damage not covered by
the vehicle warranty.

Black plate (9,1)Chevrolet Silverado Owner Manual - 2011
Vehicle Care 10-9
Cold Temperature Operation
If in an area of extreme cold,
where the temperature falls below
−29°C (−20°F), use either an
SAE 5W-30 synthetic oil or an
SAE 0W-30 engine oil. Both provide
easier cold starting for the engine
at extremely low temperatures.
Always use an oil that meets the
required specification, GM6094M.
See“What Kind of Engine Oil to
Use” for more information.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with the
starburst symbol that meet GM
Standard GM6094M are all that is
needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by
the vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably.
For the oil life system to work
properly, the system must be reset
every time the oil is changed.
On some vehicles, when the system
has calculated that oil life has been
diminished, a CHANGE ENGINE
OIL SOON message comes on
to indicate that an oil change
is necessary. See Engine Oil
Messages
on page 5‑47. Change
the oil as soon as possible within
the next 1 000 km (600 miles). It is
possible that, if driving under the best conditions, the oil life system
might not indicate that an oil change
is necessary for over a year.
However, the engine oil and
filter must be changed at least
once a year and at this time
the system must be reset.
For vehicles without the CHANGE
ENGINE OIL SOON message, an
oil change is needed when the OIL
LIFE REMAINING percentage is
near 0%. Your dealer has trained
service people who will perform this
work using genuine parts and reset
the system. It is also important to
check the oil regularly and keep it
at the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.

Automatic Transmission
Fluid (4-Speed
Transmission)
When to Check and Change
Automatic Transmission Fluid
A good time to check the automatic
transmission fluid level is when the
engine oil is changed.
Change the fluid and filter at
the intervals listed inScheduled
Maintenance
on page 11‑2and be
sure to use the transmission fluid
listed in Recommended Fluids and
Lubricants on page 11‑8.
How to Check Automatic
Transmission Fluid
Because this operation can be a
little difficult, it may be best to have
this done at the dealer service
department.
If not taken to the dealer, be sure to
follow all the instructions here or a
false reading on the dipstick could
result.
Notice: Too much or too
little fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission
to overheat. Be sure to get an
accurate reading if checking
the transmission fluid. Wait at least 30 minutes before
checking the transmission fluid level
if you have been driving:.When outside temperatures are
above 32°C (90°F).
.At high speed for quite a while.
.In heavy traffic
—especially in
hot weather.
.While pulling a trailer.
To get the right reading, the fluid
should be at normal operating
temperature, which is 82°C to
93°C (180°F to 200°F).
Get the vehicle warmed up by
driving about 24 km (15 miles) when
outside temperatures are above
10°C (50°F). If it is colder than 10°C
(50°F), drive the vehicle in 3 (Third)
until the engine temperature gauge
moves and then remains steady for
10 minutes.

Black plate (18,1)Chevrolet Silverado Owner Manual - 2011
10-18 Vehicle Care
How to Check and Add Fluid
Visually check the brake/clutch
fluid reservoir to make sure the
fluid level is at the MIN (minimum)
line on the side of the reservoir. The
brake/hydraulic clutch fluid system
should be closed and sealed.
Do not remove the cap to check
the fluid level or to top‐off the fluid
level. Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.
Engine Air Cleaner/Filter
If the vehicle has a diesel engine,
see“Pickup Models” under“Engine
Air Cleaner/Filter” in the Duramax
®
Diesel Supplement for the correct
inspection and replacement
procedures.
SeeEngine Compartment Overview
on page 10‑6for the location of the
engine air cleaner/filter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at
the scheduled maintenance
intervals and replace it at the first
oil change after each 80 000 km
(50,000 mi) interval. See Scheduled
Maintenance
on page 11‑2for
more information. If driving on
dusty/dirty conditions, inspect the
filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the engine air cleaner/filter
from the vehicle by following
Steps 1 through 6. When the engine
air cleaner/filter is removed, lightly
shake it to release loose dust and
dirt. If the engine air cleaner/filter
remains caked with dirt, a new filter
is required. Never use compressed
air to clean the filter.
