Braking
SeeBrake System Warning Light on
page 4-17.
Braking action involves perception
time and reaction time. First, you
have to decide to push on the brake
pedal. That is perception time. Then
you have to bring up your foot and do
it. That is reaction time.
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 the 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. The brakes might
not have time to cool between hard
stops. The 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 vehicle’s engine ever stops
while you are driving, brake normally
but do not pump the brakes. If you
do, the pedal could get harder to
push down. If the 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 can take longer to stop and the
brake pedal will be harder to push.
Adding non-dealer/non-retailer
accessories can affect your vehicle’s
performance. SeeAccessories
and Modifications on page 9-3.

Loading the Vehicle
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 Certi cation 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 speci c Tire and
Loading Information label is
attached to the vehicle’s 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 seatingpositions (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 in ation pressures (D).
For more information on tires and
in ation seeTires on page 9-41
andInflation - Tire Pressure on
page 9-47.
There is also important loading
information on the Certi cation
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front
and rear axle. See “Certi cation
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.
If your vehicle can tow a
trailer, seeTowing a Trailer
on page 9-77for important
information on towing a trailer,
towing safety rules and
trailering tips.
A.Vehicle Capacity Weight
for Example 1=1,000 lbs
(453 kg).
B.Subtract Occupant Weight
150 lbs (68 kg)×2=300 lbs
(136 kg).
C.Available Occupant and
Cargo Weight=700 lbs
(317 kg).

Refer to your vehicle’s Tire
and Loading Information label
for speci c 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.
Certi cation Label
A vehicle speci c Certi cation
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).
Example 2Example 3
Label Example
8-34 Driving and Operating
2009 - Pontiac Vibe Owner Manual

The GVWR includes the weight
of the vehicle, all occupants, fuel,
and cargo. Never exceed the
GVWR for the vehicle, or the
Gross Axle Weight Rating
(GAWR) for either the front
or rear axle.
And, if you do have a heavy
load, you should spread it out.
See “Steps for Determining
Correct Load Limit” earlier in
this section.
{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.Notice
:Overloading your
vehicle may cause damage.
Repairs would not be covered
by your warranty. Do not
overload your vehicle.
If you put things inside your
vehicle — like suitcases,
tools, packages, or anything
else — they will 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.
{CAUTION
Things you put inside your
vehicle can strike and injure
people in a sudden stop or
turn, or in a crash.
Put things in the rear area
of your vehicle. Try to
spread the weight evenly.
If you have fold-down rear
seats, you will nd four
anchors on the back wall
(Continued)
CAUTION (Continued)
of your trunk. You can use
these anchors to tie down
lighter loads. They are not
strong enough for heavy
things, however, so put
them as far forward as
you can in the trunk or
rear area.
Never stack heavier
things, like suitcases,
inside the vehicle so that
some of them are above
the tops of the seats.
Do not leave an
unsecured child restraint
in your vehicle.
When you carry something
inside the vehicle, secure
it whenever you can.
Do not leave a seat folded
down unless you need to.

For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A letter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply construction;
and the letter B means
belted-bias ply construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.(F) Service Description
:These
characters represent the load
range and speed rating of the
tire. The load index represents
the load carry capacity a tire is
certi ed to carry. The load index
can range from 1 to 279. The
speed rating is the maximum
speed a tire is certi ed to carry
a load. Speed ratings range
fromAtoZ.
