2009 GMC YUKON change time

Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 5-74.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-123.
{CAUTION:
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 you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the
vehicle. In an emergency, you can use a
cloth or a paper towel to do this; but be sure
to use a scraper or wire brush later, if
needed, to get all the rust or dirt off. See
Changing a Flat Tire on page 5-88.
Make sure the spare tire is stored securely. Push,
pull, and then try to rotate or turn the tire. If it
moves, tighten the cable. SeeStoring a Flat or
Spare Tire and Tools on page 5-103.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions,
inuence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which appear
when your tires have only
1/16 inch (1.6 mm) or less
of tread remaining. Some
commercial truck tires may
not have treadwear
indicators.

Maintenance Schedule
Introduction
Important: Keep engine oil at the proper level and
change as recommended.
Have you purchased the GM Protection Plan? The Plan
supplements the vehicle warranties. See the Warranty
and Owner Assistance booklet or your dealer/retailer for
details.
Maintenance Requirements
Notice:Maintenance intervals, checks, inspections,
replacement parts, and recommended uids and
lubricants as prescribed in this manual are necessary
to keep this vehicle in good working condition. Any
damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep
the vehicle in good working condition, but also helps
the environment. All recommended maintenance is
important. Improper vehicle maintenance can even affect
the quality of the air we breathe. Improper uid levels or
the wrong tire ination can increase the level of emissions
from the vehicle. To help protect the environment, and to
keep the vehicle in good condition, be sure to maintain
the vehicle properly.
Using the Maintenance Schedule
We want to help keep this vehicle in good working
condition. But we do not know exactly how you will drive
it. You might drive very short distances only a few
times a week. Or you might drive long distances all the
time in very hot, dusty weather. You might use the
vehicle in making deliveries. Or you might drive
it to work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You might need more
frequent checks and replacements. So please read
the following and note how you drive. If you have any
questions on how to keep the vehicle in good condition,
see your dealer/retailer.

Scheduled Maintenance
When the CHANGE ENGINE OIL SOON message
displays, service is required for the vehicle. Have the
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if driving under
the best conditions, the engine oil life system may not
indicate that vehicle service is necessary for over a year.
However, the engine oil and lter must be changed at
least once a year and at this time the system must be
reset. Your dealer/retailer has trained service technicians
who will perform this work using genuine parts and reset
the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-18for information on the Engine
Oil Life System and resetting the system.When the CHANGE ENGINE OIL SOON message
appears, certain services, checks, and inspections are
required. Required services are described in the
following for “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that the rst service be
MaintenanceI, the second service be MaintenanceII,
and then alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceIImay
be required more often.
MaintenanceI— Use MaintenanceIif the CHANGE
ENGINE OIL SOON message displays within 10 months
since the vehicle was purchased or MaintenanceII
was performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message displays
10 months or more since the last service or if the
message has not come on at all for one year.

Vehicle Data Recording and
Privacy
Your GM vehicle has a number of sophisticated
computers that record information about the vehicle’s
performance and how it is driven. For example, your
vehicle uses computer modules to monitor and control
engine and transmission performance, to monitor the
conditions for airbag deployment and deploy airbags in
a crash and, if so equipped, to provide antilock braking
to help the driver control the vehicle. These modules
may store data to help your dealer/retailer technician
service your vehicle. Some modules may also store data
about how you operate the vehicle, such as rate of fuel
consumption or average speed. These modules may also
retain the owner’s personal preferences, such as radio
pre-sets, seat positions, and temperature settings.
