2006 GMC SIERRA weight

It is the amount of alcohol that counts. For example, if the
same person drank three double martinis (3 ounces or
90 ml of liquor each) within an hour, the person’s BAC
would be close to 0.12 percent. A person who consumes
food just before or during drinking will have a somewhat
lower BAC level.
There is a gender difference, too. Women generally have
a lower relative percentage of body water than men.
Since alcohol is carried in body water, this means that a
woman generally will reach a higher BAC level than a
man of her same body weight will when each has the
same number of drinks.The law in most U.S. states, and throughout Canada,
sets the legal limit at 0.08 percent. In some other
countries, the limit is even lower. For example, it is
0.05 percent in both France and Germany. The BAC
limit for all commercial drivers in the United States is
0.04 percent.
The BAC will be over 0.10 percent after three to
six drinks (in one hour). Of course, as we have seen,
it depends on how much alcohol is in the drinks,
and how quickly the person drinks them.
But the ability to drive is affected well below a BAC of
0.10 percent. Research shows that the driving skills
of many people are impaired at a BAC approaching
0.05 percent, and that the effects are worse at night.
All drivers are impaired at BAC levels above
0.05 percent. Statistics show that the chance of being
in a collision increases sharply for drivers who have a
BAC of 0.05 percent or above. A driver with a BAC level
of 0.06 percent has doubled his or her chance of having a
collision. At a BAC level of 0.10 percent, the chance of
this driver having a collision is 12 times greater; at a level
of 0.15 percent, the chance is 25 times greater!
The body takes about an hour to rid itself of the alcohol
in one drink. No amount of coffee or number of cold
showers will speed that up. “I will be careful” is not the
right answer. What if there is an emergency, a need to
take sudden action, as when a child darts into the street?
A person with even a moderate BAC might not be able to
react quickly enough to avoid the collision.
4-4

Average reaction time is about three-fourths of a second.
But that is only an average. It might be less with one
driver and as long as two or three seconds or more with
another. Age, physical condition, alertness, coordination,
and eyesight all play a part. So do alcohol, drugs, and
frustration. But even in three-fourths of a second,
a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between your
vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry, or
icy; tire tread; the condition of your brakes; the weight of
the vehicle; and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the traffic
and allow realistic following distances, you will eliminate a
lot of unnecessary braking. That means better braking
and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do, the
pedal may get harder to push down. If your engine stops,
you will still have some power brake assist.But you will use it when you brake. Once the power assist
is used up, it may take longer to stop and the brake pedal
will be harder to push.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-4.
Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away, your
anti-lock brake system will check itself. You may hear a
momentary motor or clicking noise while this test is going
on. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will stay
on. SeeAnti-Lock Brake
System Warning Light on
page 3-42.
Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP problem,
both the brake and ABS warning lights will come on
accompanied by a 10-second chime.

Q:Am I likely to stall when going downhill?
A:It is much more likely to happen going uphill. But
if it happens going downhill, here is what to do.
1. Stop your vehicle by applying the regular brakes.
Apply the parking brake.
2. Shift to PARK (P), or to NEUTRAL with the manual
transmission, and, while still braking, restart the
engine.
3. Shift back to a low gear, release the parking brake,
and drive straight down.
4. If the engine will not start, get out and get help.
Driving Across an Incline
Sooner or later, an off-road trail will probably go across
the incline of a hill. If this happens, you have to decide
whether to try to drive across the incline. Here are some
things to consider:
A hill that can be driven straight up or down may
be too steep to drive across. When you go straight
up or down a hill, the length of the wheel base — the
distance from the front wheels to the rear
wheels — reduces the likelihood the vehicle will
tumble end over end. But when you drive across
an incline, the much more narrow track width — the
distance between the left and right wheels — may
not prevent the vehicle from tilting and rolling over.
Also, driving across an incline puts more weight on
the downhill wheels. This could cause a downhill
slide or a rollover.

Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. This weight is called the vehicle
capacity weight and includes the weight of all occupants,
cargo, and all nonfactory-installed options. Two labels
on your vehicle show how much weight it was designed
to carry, the Tire and Loading Information label and
the Certication/Tire label.
{CAUTION:
Do not load your 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 your
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 your vehicle.
Tire and Loading Information Label
A vehicle specic Tire and Loading Information label is
attached to the center pillar (B-pillar). With the driver’s
door open, you will nd 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.
The Tire and Loading Information label also shows
the size of the original equipment tires (C) and the
recommended cold tire ination pressures (D). For more
information on tires and ination seeTires on page 5-72
andInation - Tire Pressure on page 5-79. Label Example
4-48

There is also important loading information on the vehicle
Certication/Tire label. It tells you the Gross Vehicle
Weight Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axles. See
“Certication/Tire 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 gure equals the available amount of
cargo and luggage load capacity. For example, if the
“XXX” amount equals 1400 lbs and there will be
ve 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. SeeTowing a Trailer
on page 4-67for important information on towing
a trailer, towing safety rules and trailering tips.

Certication/Tire Label
A vehicle specic Certication/Tire label is found on
the rear edge of the driver’s door. The label shows the
size of your vehicle’s original tires and the ination
pressures needed to obtain the gross weight capacity
of your vehicle. This is called Gross Vehicle Weight
Rating (GVWR). The GVWR includes the weight of
the vehicle, all occupants, fuel, and cargo.The Certication/Tire label also tells you the maximum
weights for the front and rear axles, called Gross Axle
Weight Rating (GAWR). To nd out the actual loads on
your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help you
with this. Be sure to spread out your load equally on both
sides of the centerline.
Never exceed the GVWR for your vehicle, or the GAWR
for either the front or rear axle.
4-51

The Certication/Tire label also contains important
information about your Front Axle Reserve Capacity.
See “What is front axle reserve capacity, and how do
I calculate it?” underAdding a Snow Plow or Similar
Equipment on page 4-54.
{CAUTION:
In the case of a sudden stop or collision,
things carried in the bed of your truck could
shift forward and come into the passenger
area, injuring you and others. If you put things
in the bed of your truck, you should make sure
they are properly secured.
{CAUTION:
Do not load your 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 your 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 your vehicle.
Notice:Overloading your vehicle may cause
damage. Repairs would not be covered by your
warranty. Do not overload your vehicle.
Using heavier suspension components to get added
durability might not change your weight ratings. Ask your
dealer to help you load your vehicle the right way.
If you put things inside your vehicle — like suitcases,
tools, packages, or anything else — they go as fast
as the vehicle goes. If you have to stop or turn quickly,
or if there is a crash, they will keep going.
