Rocking Your Vehicle to Get It Out
Turn the steering wheel left and right to clear the area
around the front wheels. Turn the traction control
system off. Shift back and forth between R (Reverse)
and a forward gear, spinning the wheels as little as
possible. For a manual transmission, shift slowly
between either 1 (First) or 2 (Second) and R (Reverse),
allowing the wheels to stop before shifting into gear.
To prevent transmission wear, wait until the wheels stop
spinning before shifting gears. Release the accelerator
pedal while shifting, and press lightly on the accelerator
pedal when the transmission is in gear. Slowly spinning
the wheels in the forward and reverse directions causes
a rocking motion that could free the vehicle. If that does
not get the vehicle out after a few tries, it might need to
be towed out. If the vehicle does need to be towed out,
see Towing Your Vehicle on page 5‑33.
Loading the 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 may properly carry, the
Tire and Loading Information label and the
Certification label.
{WARNING:
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 the 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
Label Example
A vehicle specific Tire and Loading Information
label is attached to the center pillar (B-pillar) of
your vehicle. With the driver's door open, you
will find the label attached below the door latch.
This 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 inflation
pressures (D). For more information on tires and
inflation see
Tires
on page 6‑62andInflation - Tire
Pressure
on page 6‑70.
There is also important loading information on the
vehicle 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.
5-29

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.
Your vehicle is neither designed nor intended
to tow a trailer.

Refer to your vehicle's Tire and Loading
Information label for specific information about
your vehicle's capacity weight and seating
positions. The combined weight of the driver,
passengers and cargo should never exceed your
vehicle's capacity weight.
Certification Label
A vehicle specific Certification label is attached
to the rear edge of the driver's door. 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. Never exceed the
GVWR for your vehicle, or the Gross Axle Weight
Rating (GAWR) for either the front or rear axle.
Do not load your vehicle with more weight than it
was designed to carry. See
“Steps for Determining
Correct Load Limit” earlier in this section.
{WARNING:
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 the vehicle handles. These could
cause you to lose control and crash.
Also, overloading can shorten the life of
the vehicle.
Notice :Overloading the vehicle may cause
damage. Repairs would not be covered by the
vehicle warranty. Do not overload the vehicle.

(F) Uniform Tire Quality Grading (UTQG):Tire
manufacturers are required to grade tires based
on three performance factors: treadwear, traction
and temperature resistance. For more information
see Uniform Tire Quality Grading
on page 6‑79.
(G) Maximum Cold Inflation Load Limit
:
Maximum load that can be carried and the
maximum pressure needed to support that load.
Tire Size
The following illustration shows an example of a
typical passenger (p‐metric) vehicle tire size.
(A) Passenger (P‐Metric) Tire:The United
States version of a metric tire sizing system.
The letter P as the first character in the tire size
means a passenger vehicle tire engineered
to standards set by the U. S. Tire and Rim
Association. (B) Tire Width
:The three‐digit number indicates
the tire section width in millimeters from sidewall
to sidewall.
(C) Aspect Ratio
:A two‐digit number that
indicates the tire height‐to‐width measurements.
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 index and speed rating of the
tire. The load index represents the load carry
capacity a tire is certified to carry. The speed
rating is the maximum speed a tire is certified
to carry a load.
