2. Remove the towing hook and
wheel nut wrench located behind
the cargo area cover on the
driver's side.
3. Screw the towing hook into the
hole, and tighten it with the wheel
nut wrench.
To avoid damage to your vehicle, use
the towing hook for straight, flat
ground towing only. Do not tow at an
angle. The tow hook should not be used
to tow the vehicle onto a flat bed. Do
not use it as a tie down.

Technical Information

Your vehicle has several identifying
numbers located in various places.
The vehicle identification number
(VIN) is the 17-digit number your
dealer uses to register your vehicle
for warranty purposes. It is also
necessary for licensing and insuring
your vehicle. The easiest place to
find the VIN is on a plate fastened to
the top of the dashboard. You can
see it by looking through the
windshield on the driver's side. It is
also on the certification label
attached to the driver's doorjamb,
and is stamped on the engine
compartment bulkhead. The VIN is
also provided in bar code on the
certification label.

The tires on your vehicle meet all U.
S. Federal Safety Requirements. All
tires are also graded for treadwear,
traction, and temperature
performance according to
Department of Transportation (DOT)
standards. The following explains
these gradings.
Uniform Tire Quality Grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.Treadwear
The treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions on a specified
government test course. For
example, a tire graded 150 would
wear one and one-half (1 1/2) times
as well on the government course as
a tire graded 100. The relative
performance of tires depends upon
the actual conditions of their use,
however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.Traction
The traction grades, from highest to
lowest, are AA, A, B, and C. Those
grades represent the tire's ability to
stop on wet pavement as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction
performance.
Warning: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.

Technical Information

Temperature
The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire failure. The
grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No.
109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the
minimum required by law.Warning: The temperature grade for
this tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.DOT Tire Quality Grading (U.S. Vehicles)582

The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
Tire SizeWhenever tires are replaced, they
should be replaced with tires of the
same size. Following is an example
of tire size with an explanation of
what each component means.
P255/50R19 103H
P－Vehicle type (P indicates
passenger vehicle).
255－Tire width in millimeters.
50－Aspect ratio (the tire's
section height as a
percentage of its width).
R－Tire construction code (R
indicates radial).
19－Rim diameter in inches.103－Load index (a numerical code
associated with the
maximum load the tire can
carry).
H－Speed symbol (an
alphabetical code indicating
the maximum speed rating).
Tire Identification Number (TIN)The tire identification number (TIN)
is a group of numbers and letters that
look like the following example. TIN
is located on the sidewall of the tire.
DOT B97R FW6X 2202
DOT－This indicates that the tire
meets all requirements of
the U.S. Department of
Transportation.

identification mark.
