Opening the Fuel Fill Door
ManuallyIf the fuel fill door release button
does not work, use the release lever
inside the rear fuse box lid in the
cargo area.
To open the fuel fill door, pull the
release lever rearward.Emergency Towing
If your vehicle needs to be towed,
call a professional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
The only way you can safely tow
your vehicle is with flat-bed
equipment.
The operator will load
your vehicle on the back of a truck.
Any other method of towing will
damage the drive system. When you
contact the towing agency, inform
them a flat-bed is required.
Towing with only two tires on the
ground will damage parts of the all-
wheel-drive system. Your vehicle should
be transported on a flat-bed truck or
trailer.

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.DOT Tire Quality Grading (U.S. Vehicles)45408/06/06 16:58:07 09 ACURA MDX MMC North America Owner's M 50 31STX620 enu
2009 MDX

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.

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. The following is an
example of tire size with an
explanation of what each component
means.P255/55R18 104H
P －Vehicle type (P indicates
passenger vehicle).
255 －Tire width in millimeters.
55 －Aspect ratio (the tire's
section height as a
percentage of its width).
R －Tire construction code (R
indicates radial).
18 －Rim diameter in inches. 104
－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.
B97R －Manufacturer's
identification mark.

Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label.
(If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale
when one or more of your tires is
significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure.Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.

－Required Federal Explanation45808/06/06 16:58:07 09 ACURA MDX MMC North America Owner's M 50 31STX620 enu
2009 MDX

Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS
malfunction indicator is combined
with the low tire pressure telltale.
When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS from
functioning properly.Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.
