Roof Rack System
Roof Rack
{CAUTION
If something is carried on top of
the vehicle that is longer or wider
than the roof rack — like paneling,
plywood, or a mattress — the wind
can catch it while the vehicle is
being driven. The item being
carried could be violently torn off,
and this could cause a collision,
and damage the vehicle. Never
carry something longer or wider
than the roof rack on top of the
vehicle unless using a GM
Certified accessory carrier.Notice:
Loading cargo on the
roof rack that weighs more than
75 kg (165 lbs) or hangs over
the rear or sides of the vehicle
may damage the vehicle.
Load cargo so that it rests evenly
between the crossrails, making
sure to fasten cargo securely. To prevent damage or loss of cargo
when driving, check to make sure
cross rails and cargo are securely
fastened. Loading cargo on the roof
rack will make the vehicle’s center of
gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden
braking or abrupt maneuvers,
otherwise it may result in loss of
control. If driving for a long distance,
on rough roads, or at high speeds,
occasionally stop the vehicle to make
sure the cargo remains in its place.
Do not exceed the maximum vehicle
capacity when loading the vehicle.
For more information on vehicle
capacity and loading, see
Vehicle
Load Limits on page 8-12 .

Vehicle Load Limits
It is very important to know how
much weight your vehicle can
carry. Two labels on the vehicle
show how much weight it may
properly carry, the Tire and
Loading Information label and the
Certification label.
{CAUTION
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR), or
either the maximum front or
rear Gross Axle Weight Rating
(GAWR). If you do, parts on
the vehicle can break, and it
can change the way your
vehicle handles. These could
cause you to lose control and
crash. Also, overloading can
shorten the life of the vehicle. Tire and Loading Information
Label
A vehicle specific Tire and
Loading Information label is
attached to the vehicle’s center
pillar (B-pillar). With the driver’s
door open you will find the label
attached below the door lock post
(striker). The Tire and Loading
Information label shows the
number of occupant seating
positions (A), and the maximum
vehicle capacity weight (B)
in kilograms and pounds. This weight includes the weight
of all occupants, cargo, and all
nonfactory-installed options.
The Tire and Loading Information
label also shows the tire size of
the original equipment tires (C),
and the recommended cold tire
inflation pressures (D). For more
information on tires and inflation
see
Tires on page 9-43 andTire
Pressure on page 9-49.
There is also important loading
information on the Certification
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front and
rear axle. See “Certification
Label” later in this section.

Steps for Determining Correct
Load Limit
1.Locate the statement “The
combined weight of occupants
and cargo should never
exceed XXX kg or XXX lbs”
on your vehicle’s placard.
2.Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “XXX” amount
equals 1400 lbs and there will
be five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs
(1400 −750 (5 x 150) =
650 lbs).
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing
a trailer, the load from your
trailer will be transferred
to your vehicle. Consult this
manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.
If your vehicle can tow a trailer,
see Trailer Towing on page 8-48
for important information on
towing a trailer, towing safety
rules and trailering tips.

Refer to your vehicle’s Tire and
Loading Information label for
specific information about the
vehicle’s capacity weight and
seating positions. The combined weight of the driver, passengers,
and cargo should never exceed
the vehicle’s maximum vehicle
capacity weight.
Certication Label
A vehicle specific Certification
label is attached to the center
pillar, near the driver’s door latch.
It tells you the gross weight
capacity of your vehicle, called
the Gross Vehicle Weight Rating
(GVWR). The GVWR includes
the weight of the vehicle, all
occupants, fuel, and cargo.

Driving Characteristics
and Towing Tips
{CAUTION
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly.
For example, if the trailer is too
heavy, the brakes may not work
well — or even at all. The driver
and passengers could be seriously
injured. The vehicle may also be
damaged; the resulting repairs
would not be covered by the
vehicle warranty. Pull a trailer only
if all the steps in this section have
been followed. Ask your dealer/
retailer for advice and information
about towing a trailer with the
vehicle.
The vehicle can tow a trailer if it is
equipped with the proper trailer
towing equipment. To identify the
trailering capacity of the vehicle, see Trailer Towing on page 8-48
.
Trailering is different than just driving
the vehicle by itself. Trailering means
changes in handling, acceleration,
braking, durability and fuel economy.
Successful, safe trailering takes
correct equipment, and it has to be
used properly.
The following information has many
time-tested, important trailering tips
and safety rules. Many of these are
important for your safety and that of
your passengers. So please read this
section carefully before pulling a
trailer.
Load-pulling components such as
the engine, transmission, wheel
assemblies and tires are forced to
work harder against the drag of
the added weight. The engine
is required to operate at relatively
higher speeds and under greater
loads, generating extra heat.
Also, the trailer adds considerably
to wind resistance, increasing
the pulling requirements.
Pulling A Trailer
Here are some important points:
•There are many different laws,
including speed limit restrictions,
having to do with trailering. Make
sure the rig will be legal, not only
where you live but also where you
will be driving. A good source for
this information can be state or
provincial police.
•Do not tow a trailer at all during
the first 1 600 km (1,000 miles)
the new vehicle is driven.
The engine, axle or other
parts could be damaged.
•Then, during the first 800 km
(500 miles) that a trailer is towed,
do not drive over 80 km/h
(50 mph) and do not make starts
at full throttle. This helps the
engine and other parts of the
vehicle wear in at the heavier
loads.
8-44 Driving and Operating

Trailer Towing
Before pulling a trailer, there are
three important considerations that
have to do with weight:
•The weight of the trailer.
•The weight of the trailer tongue.
•The total weight on your
vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
680 kg (1,500 lbs). But even
that can be too heavy.
It depends on how the rig is used.
For example, speed, altitude, road
grades, outside temperature and
how much the vehicle is used to pull
a trailer are all important. It can
depend on any special equipmenton the vehicle, and the amount of
tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue”
later in this section for more
information.
Maximum trailer weight is calculated
assuming only the driver is in the tow
vehicle and it has all the required
trailering equipment. The weight of
additional optional equipment,
passengers and cargo in the tow
vehicle must be subtracted from the
maximum trailer weight.
Ask your dealer/retailer for our
trailering information or advice, or
you can write us at our Customer
Assistance Offices. See
Customer
Assistance Offices on page 12-3
for more information.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes
the curb weight of the vehicle, any
cargo carried in it, and the people
who will be riding in the vehicle. If
there are a lot of options, equipment,
passengers or cargo in the vehicle, it
will reduce the tongue weight the
vehicle can carry, which will also
reduce the trailer weight the vehicle
can tow. If towing a trailer, the
tongue load must be added to the
GVW because the vehicle will be
carrying that weight, too. See Vehicle
Load Limits on page 8-12 for more
information about the vehicle’s
maximum load capacity.
