Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Disconnect the battery.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals.
If you need to park your vehicle f or
an extended period (more than 1
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.
Fill the f uel tank.
Push the tabs and remove the
cover by pulling it up caref ully.
To reinstall the cover, put the tabs
of the cover back to the original
position properly.
Turn the knob of the cover to
LOCK position as shown in the
illustration.

Your vehicle is equipped with the
Michelin PAX system. Since each
Michelin PAX system tire has an
inner support ring that allows it to
continue running without air, it may
be dif f icult to immediately judge
f rom its appearance if a tire is
punctured. Your vehicle is also
equipped with a tire pressure
monitoring system (TPMS), and this
system may be your f irst detection of
a f lat tire.If the indicator and the message
come on again, you probably have a
flat tire. In this case, you will see a
‘‘PAX SYSTEM WARNING’’
message on the multi-inf ormation
display.
The TPMS monitors the air pressure
of all f our tires whenever the ignition
switch is in the ON (II) position. It
will immediately sense if a tire starts
to lose its pressure, and give you
warning with the low tire pressure/
TPMS indicator in the instrument
panel and a ‘‘CHECK TIRE
PRESSURE’’ message on the multi-
inf ormation display. If the indicator
and the warning message do not
come on again af ter you inf late the
tire to its correct air pressure (see page ), it was probably a natural
loss of the air pressure and you can
continue driving as bef ore.

If you get a f lat tire, never try to
repair it yourself , and never replace a
flat tire with a compact spare tire.
With the PAX system tires, you can
drive up to about 125 miles (200 km)
even if one or more of your tires are
punctured. This allows you to drive
to the nearest Acura dealer or
authorized Michelin PAX system
dealer to have the tire(s) repaired.The above message shows that you
are driving your vehicle on a flat tire,
andshouldobservethe‘‘RUNFLAT
DRIVING’’ speed limit of 50 mph
(80 km/h). Drive to your nearest
Acura dealer or authorized Michelin
PAX system dealer, or call the PAX
help hotline at 1-877-PAXTIRE
(1-877-729-8473).If the display changes to the above
message, it means that ‘‘RUN FLAT
DRIVING’’ is nearing the limit, and
you have to stop driving soon. Take
your vehicle to the nearest Acura
dealer or authorized Michelin PAX
system dealer as soon as possible.
Follow the instructions shown on the
multi-inf ormation display, and drive
very caref ully.

If you see the above message on the
multi-inf ormation display, you have
reached the limit of run f lat driving,
and you should stop driving
immediately. Be aware that if you
continue to drive, the noise and
vibration level f rom the tire will
increase signif icantly, and the tire
may no longer be repairable.Stop driving immediately when
you see a ‘‘RUN FLAT LIMIT
STOP DRIVING’’ message on the
multi-inf ormation display.
Continuous driving af ter this
message will make it impossible to
repair the tire.
Call a prof essional towing service
who can transport your vehicle on
f lat-bed equipment. Never tow your vehicle behind another vehicle with a
rope or chain. Flat-bed equipment is
the only way to transport your
vehicle.
Do not drive f aster than 50 mph
(80 km/h).
Drive caref ully. Your vehicle may
handle dif f erently f rom when the
tires are properly inf lated,
especially when cornering.
In its run f lat mode, a PAX system
tire is somewhat noisier than when
it is f ully inf lated, this is normal.
Although your vehicle is capable of
runflatdriving,youshouldalways
observe the f ollowing: If you cannot f ind an Acura dealer or
an authorized Michelin PAX system
dealer where you are driving, call the
PAX help hotline at 1-877-PAXTIRE
(1-877-729-8473).

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or replaced,
and put it back on your vehicle as
soon as you can.
Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
samewheel.Thesparetireisnot
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
Do not mount snow chains on the
compact spare tire.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
Follow these precautions:
Never exceed 50 mph (80 km/h).
This tire gives a harsher ride and
less traction on some road
surf aces. Use greater caution
while driving.
After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
Af ter several miles (kilometers)
driving with the spare, this
indicator begins to f lash, then
stays on again. You will also see a
‘‘CHECK TPMS SYSTEM’’
message on the multi-inf ormation
display (see page ). 375

To use the towing hook:Remove the cover f rom the f ront
bumper by pushing the right
corner edge of the cover with a
f inger until the cover comes out as
shown in the illustration.
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, inf orm
them a f lat-bed is required.
If your vehicle needs to be towed,
call a prof essional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous. If your vehicle gets stuck in sand,
mud, or snow, call a towing service
to pull it out (see the previous
column).
For very short distances, such as
f reeing the vehicle, you can use the
detachable towing hook that mounts
on the anchor in the f ront bumper.

The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades.
Quality grades can be f ound where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied 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 perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate.The traction grades, f rom 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
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.

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 specif ied 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 f ailure. The
grade C corresponds to a level of
perf ormance which all passenger car
tires must meet under the Federal
Motor Vehicle Saf ety Standard No.
109. Grades B and A represent
higher levels of perf ormance on the
laboratory test wheel than the
minimum required by law.Warning: The temperature grade f or
this tire is established f or a tire that
is properly inf lated and not
overloaded. Excessive speed,
underinf lation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire f ailure.
