Additional Required Services -
Severe
(1) Vehicles with different size front
and rear tires do not have tire
rotation. See Tire Rotation0307.
(2) Or every two years, whichever
comes first. More frequent passenger
compartment air filter replacement
may be needed if driving in areas with
heavy traffic, poor air quality, high
dust levels, or environmental
allergens. Passenger compartment air
filter replacement may also be needed
if there is reduced airf low, window
fogging, or odors. Your GM dealer can
help determine when to replace the
filter.
(3) Visually check all fuel and vapor
lines and hoses for proper attachment,
connection, routing, and condition. (4)
Or every four years, whichever
comes first. If driving in dusty
conditions, inspect the filter at each
oil change or more often as needed.
(5) Do not directly power wash the
transfer case and/or front/rear axle
output seals. High pressure water can
overcome the seals and contaminate
the transfer case fluid. Contaminated
fluid will decrease the life of the
transfer case and/or axles and should
be replaced.
(6) Or every five years, whichever
comes first. See Cooling System0269.
(7) Or every 10 years, whichever
comes first. Inspect for fraying,
excessive cracking, or damage; replace,
if needed.
(8) Replace brake fluid every five
years. See Brake Fluid 0276.Special Application

CUSTOMER INFORMATION 363
Scheduling Service
Appointments
When the vehicle requires warranty
service, contact your dealer and
request an appointment. By
scheduling a service appointment and
advising the service consultant of
your transportation needs, your dealer
can help minimize your
inconvenience.
If the 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, let them know this, and
ask for instructions.
If your dealer requests you to bring
the vehicle for service, you are urged
to do so as early in the work day as
possible to allow for same-day repair.
Courtesy Transportation
Program
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), extended
powertrain, and/or hybrid-specific
warranties in both the U.S. and
Canada.
Several Courtesy Transportation
options are available to assist in
reducing inconvenience when
warranty repairs are required.
Courtesy Transportation is not a part
of the New Vehicle Limited Warranty.
A separate booklet entitled“Limited
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 do so, your dealer
may offer the following transportation
options:
Shuttle Service
This includes one-way or round-trip
shuttle service within reasonable time
and distance parameters of your
dealer's area.
Public Transportation or Fuel
Reimbursement
If overnight warranty repairs are
needed, and public transportation is
used, the expense must be supported
by original receipts and within the
maximum amount allowed by GM for
shuttle service. If U.S. customers
arrange their own transportation,
limited reimbursement for reasonable
fuel expenses may be available. Claim
amounts should reflect actual costs
and be supported by original receipts.
See your dealer for information.

366 CUSTOMER INFORMATION
Managing the Vehicle Damage
Repair Process
In the event that the vehicle requires
damage repairs, GM recommends that
you take an active role in its repair.
If you have a pre-determined repair
facility of choice, take the vehicle
there, or have it towed there. Specify
to the facility that any required
replacement collision parts be original
equipment parts, either new Genuine
GM parts or recycled original GM
parts. Remember, recycled parts will
not be covered by the GM vehicle
warranty.
Insurance pays the bill for the repair,
but you must live with the repair.
Depending on your policy limits, your
insurance company may initially value
the repair using aftermarket parts.
Discuss this with the repair
professional, and insist on Genuine
GM parts. Remember, if the vehicle is
leased, you may be obligated to have
the vehicle repaired with Genuine GM
parts, even if your insurance coverage
does not pay the full cost.If another party's insurance company
is paying for the repairs, you are not
obligated to accept a repair valuation
based on that insurance company's
collision policy repair limits, as you
have no contractual limits with that
company. In such cases, you can have
control of the repair and parts choices
as long as the cost stays within
reasonable limits.
