lubrication may be required
when the vehicle is exposed
to a corrosive environment.
Applying silicone grease on
weatherstrips with a clean cloth
makes them last longer, seal
better, and not stick or squeak.

An Emission Control Service.
The U.S. Environmental
Protection Agency or the
California Air Resources Board
has determined that the failure
to perform this maintenance
item will not nullify the emission
warranty or limit recall liability
prior to the completion of
the vehicle's useful life.
We, however, urge that all
recommended maintenance
services be performed at the
indicated intervals and the
maintenance be recorded.First Engine Oil Change After
Every 160 000 km/100,000 Miles
.Automatic transmission fluid
change (normal service).

.Four‐wheel drive only: Transfer
case fluid change (normal
service). Check vent hose at
transfer case for kinks and
proper installation. Check to be
sure vent hose is unobstructed,
clear, and free of debris. During
any maintenance, if a power
washer is used to clean mud
and dirt from the underbody,
care should be taken to not
directly spray the transfer case
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 should be
replaced.

Courtesy Transportation
Program (U.S. and
Canada)
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“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
inconvenience by providing several
transportation options. Depending
on the circumstances, the dealer
can offer one of the following:
Shuttle Service
Shuttle service is the preferred
means of offering Courtesy
Transportation. Dealers may 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
within reasonable time and distance
parameters of the dealer's area. Public Transportation or Fuel
Reimbursement
If the vehicle requires overnight
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 reflect
actual costs and be supported by
original receipts. See the dealer for
information regarding the allowance
amounts for reimbursement of fuel
or other transportation costs.

Black plate (12,1)GMC Sierra Owner Manual - 2011
13-12 Customer Information
Courtesy Rental Vehicle
The dealer may arrange to provide
you with a courtesy rental vehicle or
reimburse you for a rental vehicle
that you obtain if the vehicle is kept
for an overnight warranty repair.
Rental reimbursement will be limited
and must be supported by original
receipts. This requires that you sign
and complete a rental agreement
and meet state/provincial, 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.
It may not be possible to provide a
like vehicle as a courtesy rental.Additional Program
Information
All program options, such as shuttle
service, may not be available at
every dealer. Please contact the
dealer for specific information
about availability. All Courtesy
Transportation arrangements
will be administered by appropriate
dealer personnel.
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.
Collision Damage Repair
(U.S. and Canada)
If the vehicle is involved in a
collision and it is damaged, have
the damage repaired by a qualified
technician using the proper
equipment and quality replacement
parts. Poorly performed collision
repairs diminish the vehicle resale
value, and safety performance can
be compromised in subsequent
collisions.
Collision Parts
Genuine GM Collision parts are new
parts made with the same materials
and construction methods as the
parts with which the vehicle was
originally built. Genuine GM
Collision parts are the best choice to
ensure that the vehicle's designed
appearance, durability, and safety
are preserved. The use of Genuine
GM parts can help maintain the GM
New Vehicle Limited Warranty.

Vehicle Data
Recording and
Privacy
This GM vehicle has a number of
sophisticated computers that record
information about the vehicle’s
performance and how it is driven.
For example, the 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 the dealer technician
service the 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.
Event Data Recorders
This vehicle has an Event Data
Recorder (EDR). The main purpose
of an EDR is to record, in certain
crash or near crash-like situations,
such as an airbag deployment or
hitting a road obstacle, data that
will assist in understanding how
a vehicle's systems performed.
The EDR is designed to record data
related to vehicle dynamics and
safety systems for a short period of
time, typically 30 seconds or less.
The EDR in this vehicle is designed
to record such data as:
.How various systems in the
vehicle were operating.
.Whether or not the driver and
passenger safety belts were
buckled/fastened.
.How far, if at all, the driver was
pressing the accelerator and/or
brake pedal.
.How fast the vehicle was
traveling.
