The proper replacement parts, uids, and lubricants to
use are listed inRecommended Fluids and Lubricants
on page 6-12andMaintenance Replacement Parts
on page 6-14. When your vehicle is serviced, make sure
these are used. All parts should be replaced and all
necessary repairs done before you or anyone else
drives the vehicle. We recommend the use of genuine
parts from your dealer/retailer.
Scheduled Maintenance
When the CHANGE ENGINE OIL message in the
Driver Information Center (DIC) comes on, it means
that service is required for your vehicle. SeeDIC
Warnings and Messages on page 3-56. Have your
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if you are
driving under the best conditions, the engine oil life
system may not indicate that vehicle service is
necessary for over a year. However, your 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,
you must service your vehicle within 3,000 miles
(5 000 km) since your last service. Remember to reset
the oil life system whenever the oil is changed. See
Engine Oil Life System on page 5-16for information on
the Engine Oil Life System and resetting the system.
When the CHANGE ENGINE OIL 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 your rst service be MaintenanceI,
your second service be MaintenanceII, and that you
alternate MaintenanceIand MaintenanceIIthereafter.
However, in some cases, MaintenanceIImay be
required more often.
MaintenanceI— Use MaintenanceIif the CHANGE
ENGINE OIL message comes on within 10 months since
the vehicle was purchased or MaintenanceIIwas
performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message comes on
10 months or more since the last service or if the
message has not come on at all for one year.

If your vehicle cannot be scheduled into the service
department immediately, keep driving it until it can be
scheduled for service, unless, of course, the problem is
safety-related. If it is, please call your dealership/retailer,
let them know this, and ask for instructions.
If the dealer/retailer requests that you simply drop the
vehicle off for service, you are urged to do so as early in
the work day as possible to allow for the same day repair.
Courtesy Transportation
To enhance your ownership experience, we and our
participating dealers are proud to offer Courtesy
Transportation, a customer support program for vehicles
with the Bumper to Bumper (Base Warranty Coverage
period in Canada) and extended powertrain warranty
in both the U.S. and Canada.
Several courtesy transportation options are available to
assist in reducing your inconvenience when warranty
repairs are required.
Courtesy Transportation is not a part of the New Vehicle
Limited Warranty. A separate booklet entitled “Warranty
and Owner Assistance Information” furnished with
each new vehicle provides detailed warranty coverage
information.
Transportation Options
Warranty service can generally be completed while you
wait. However, if you are unable to wait, GM helps
to minimize your inconvenience by providing several
transportation options. Depending on the circumstances,
your dealer can offer you one of the following:
Shuttle Service
Participating dealers can provide shuttle service to get
you to your destination with minimal interruption of
your daily schedule. This includes one-way or round trip
shuttle service to a destination up to 10 miles (16 km)
from the dealership.
Public Transportation or Fuel
Reimbursement
If your vehicle requires warranty repairs, and public
transportation is used instead of the dealer’s shuttle
service, the expense must be supported by original
receipts and can only be up to the maximum amount
allowed by GM for shuttle service. In addition, for
U.S. customers, should you arrange transportation
through a friend or relative, limited reimbursement for
reasonable fuel expenses may be available. Claim
amounts should reect actual costs and be supported
by original receipts. See your dealer for information
regarding the allowance amounts for reimbursement of
fuel or other transportation costs.
