Canadian Roadside Assistance
Vehicles purchased in Canada have an extensive
Roadside Assistance program accessible from anywhere
in Canada or the United States. Please refer to the
Warranty and Owner Assistance Information book.
Courtesy Transportation
GMC has always exemplified quality and value in its
offering of motor vehicles. To enhance your ownership
experience, we and our participating dealers are
proud to offer Courtesy Transportation, a customer
support program for new vehicles.
The Courtesy Transportation program is offered to retail
purchase/lease customers in conjunction with the
Bumper-to-Bumper coverage provided by the New
Vehicle Limited Warranty. Several transportation options
are available when warranty repairs are required.
This will reduce your inconvenience during warranty
repairs.
Plan Ahead When Possible
When your vehicle requires warranty service, you
should contact your dealer and request an appointment.
By scheduling a service appointment and advising
your service consultant of your transportation needs,
your dealer can help minimize your inconvenience.
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, let
them know this, and
ask for instructions.
If the dealer 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.
Transportation Options
Warranty service can generally be completed while you
wait. However,
if you are unable to wait, GMC helps
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 you with shuttle
service to get you to your destination with minimal
interruption of your daily schedule. This includes a one
way shuttle ride to a destination up to
10 miles from
the dealership.
7-7

Public Transportation or Fuel
Reimbursement
If your vehicle requires overnight warranty repairs,
reimbursement up to
$30 per day (five days maximum)
may be available for the use of public transportation
such as taxi or bus. In addition, should you arrange
transportation through a friend or relative,
reimbursement for reasonable fuel expenses up
to
$10 per day (five day maximum) may be available.
Claim amounts should reflect actual costs and be
supported by original receipts.
Courtesy Rental Vehicle
When your vehicle is unavailable due to overnight
warranty repairs, your dealer may arrange
to provide
you with a courtesy rental vehicle or reimburse you for a
rental vehicle you obtained, at an actual cost, up to a
maximum of
$30.00 per day supported by receipts. This
requires that you sign and complete a rental agreement
and meet state, local and rental vehicle provider
requirements. Requirements vary and may include
minimum age requirements, insurance coverage, credit
card, etc. You are responsible for fuel usage charges
and may also be responsible for taxes, levies,
usage fees, excessive mileage or rental usage beyond
the completion of the repair.
Generally
it is not possible to provide a like-vehicle as a
courtesy rental.
Additional Program Information
Courtesy Transportation is available during the
Bumper-to-Bumper warranty coverage period, but it
is
not
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.
Courtesy Transportation is available only at participating
dealers and all program options, such as shuttle
service, may not be available at every dealer. Please
contact your dealer for specific information about
availability.
All Courtesy Transportation arrangements
will be administered by appropriate dealer personnel.
Canadian Vehicles: For warranty repairs during
the Complete Vehicle Coverage period of the General
Motors of Canada New Vehicle Limited Warranty,
alternative transportation may be available under the
Courtesy Transportation Program. Please consult
your dealer for details.
General Motors reserves the right to unilaterally modify,
change or discontinue Courtesy Transportation at
any time and to resolve all questions of claim eligibility
pursuant to the terms and conditions described
herein at its sole discretion.

Supplement to the 2003 Silverado, Sierra, Tahoe, Suburban,
r’s Manual
Passenger Sensing System
Accident statistics show that children are safer if they are I
restrained in the rear rather than the front seat. General
Motors, therefore, recommends that child restraints be
secured in
a rear seat, including an infant riding in a
rear-facing infant seat,
a child riding in a forward-facing
child seat and an older child riding in a booster seat.
Never put a child in rear-facing child restraint in the tight
front passenger seat unless your vehicle has the
passenger sensing system and the passenger air bag
status indicator
shows off. Never put a rear-facing child
restraint in the right front passenger seat unless the air
bag
is off.
A child in a rear-facing child restraint can be
seriously injured or killed
if the right front
passenger’s air bag inflates. This
is because
the back
of the rear-facing child restraint
would be very close to the inflating air bag.
Be
sure the air bag is off before using a
rear-facing child restraint in the right front seat
position.
CAUTION: (Continued)

U.S.A.
Part No. 15189747 ‘Copyright General Motors
Corporation

All Rights Reserved

Even though the passenger sensing system is
designed to turn
off the passenger’s frontal air
bag if
the system detects a rear-facing child
restraint, no system
is fail-safe, and no one
can guarantee that an air bag will not deploy
under some unusual circumstance, even
though it
is turned off. General Motors,
therefore, recommends that rear-facing child
restraints be secured
in the rear seat whenever
~ possible, even if the air bag is off.
The passenger sensing system is designed to turn off
the right front passenger’s frontal air bag if:
the right front passenger seat is unoccupied
the system determines that an infant is present in a
the system determines that a small child is present
rear-facing infant seat
in a forward-facing child restraint
the system determines that a small child is present
in
a booster seat
a right front passenger takes hislher weight off of
the seat for a period of time
the right front passenger seat is occupied by a
smaller person, such as a child
who has outgrown
child restraints
or if there is a critical problem with the air bag
system or the passenger sensing system.
For
some children who have outgrown child restraints
and for
very small adults, the passenger sensing system
may
or may not turn off the right front passenger’s
frontal air bag, depending upon the person’s seating
posture and body build. Everyone in your vehicle
who has outgrown child restraints should wear
a safety
belt properly
- whether or not there is an air bag
for that person.
