(e)Make sure the safety belt reminder light and safety
belt assemblies are working properly. Look for any other
loose or damaged safety belt system parts. If you see
anything that might keep a safety belt system from doing
its job, have it repaired. Have any torn or frayed safety
belts replaced. Also see Checking the Restraint Systems
on page 1-88.
(f)Lubricate all key lock cylinders, body door hinges,
hood latch assembly, secondary latch, pivots, spring
anchor, release pawl, tailgate hinges, tailgate linkage,
tailgate handle pivot points, latch bolt, fuel door
hinge, locks, and folding seat hardware. More frequent
lubrication may be required when exposed to a
corrosive environment. Applying silicone grease on
weatherstrips with a clean cloth will make them
last longer, seal better, and not stick or squeak.
(g)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.(h)Change automatic transmission fluid and filter if the
vehicle Gross Vehicle Weight Rating (GVWR) is
over 8600 lbs or if the vehicle is mainly driven under
one or more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
(i)Drain, flush, and refill cooling system. This service
can be complex; you should have your dealer/retailer
perform this service. See Engine Coolant on page 5-29
for what to use. Inspect hoses. Clean radiator,
condenser, pressure cap, and filler neck. Pressure test
the cooling system and pressure cap.
(j)A fluid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired and
the fluid level checked. Add fluid if needed.
(k)Inspect system. Check all fuel and vapor lines and
hoses for proper hook-up, routing, and condition. Check
that the purge valve, if the vehicle has one, works
properly. Replace as needed.
6-9

(l)Extreme Duty Service: Change transfer case fluid if
the vehicle is mainly driven off-road in four-wheel
drive, or is used for heavy trailer towing. Farming,
mining, forestry, and Department of Natural
Resources (DNR) vehicles meet this definition.
(m)Severe Service: Change transfer case fluid if the
vehicle is mainly used for trailer towing or driven in city
traffic, wet environment, or high ambient temperatures.
(n)Vehicles with diesel engine or with GVWR above
10,000 lbs (4 536 kg) only: Inspect shields for damage
or looseness. Adjust or replace as required. This is
a Noise Emission Control Service. Applicable to vehicles
sold in the United States and recommended for
vehicles sold in Canada.
(p)If you drive regularly under dusty conditions, inspect
the filter or change indicator (if equipped) at each
engine oil change.
(q)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.Owner Checks and Services
These owner checks and services should be performed
at the intervals specied to help ensure the safety,
dependability, and emission control performance of your
vehicle. Your dealer/retailer can assist you with these
checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-14.
At the First 100, 1,000 and 6,000
Miles (160, 1 600 and 10 000 km)
For vehicles with dual wheels, check dual wheel
nut torque. For proper torque, seeCapacities and
Specifications on page 5-133.
At Each Fuel Fill
It is important to perform these underhood checks at
each fuel fill.

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 your 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
This data can help provide a better understanding of the
circumstances in which crashes and injuries occur.Important:EDR data is recorded by your vehicle
only if a non-trivial crash situation occurs; no data is
recorded by the EDR under normal driving conditions and
no personal data (e.g., name, gender, age, and crash
location) is recorded. However, other parties, such as law
enforcement, could combine the EDR data with the type
of personally identifying data routinely acquired during a
crash investigation.
To read data recorded by an EDR, special equipment is
required, and access to the vehicle or the EDR is needed.
In addition to the vehicle manufacturer, other parties,
such as law enforcement, that have the special
equipment, can read the information if they have access
to the vehicle or the EDR.
GM will not access this data or share it with others
except: with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the lessee; in
response to an official request of police or similar
government office; as part of GM’s defense of litigation
through the discovery process; or, as required by law.
Data that GM collects or receives may also be used for
GM research needs or may be made available to others
for research purposes, where a need is shown and the
data is not tied to a specic vehicle or vehicle owner.
