Keeping the tires properly inflated
provides the best combination of
handling, tread life, and riding
comfort.
Underinflated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinflated tires can make your
vehicleridemoreharshly,are
more prone to damage from road
ha zards, and wear unevenly.
Thetirepressuremonitoringsystem
(TPMS)will warnyouwhenatire
pressu re is low. See page for
inf ormation on the TPMS.
The f ollowing pages give more
detailed inf ormation on how to take
care of your tires and what to do
when they need to be replaced. To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.
Clean the wheels as you would the
rest of the exterior. Wash them with
thesamesolution,andrinsethem
thoroughly.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum f rom corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stif f
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a sof t brush or sponge.

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this

to6psi(30to40kPa,0.3to

pressure gauge and use it whenever
you check your tire pressures. This
will make it easier for you to tell if a
pressu re loss is due to a tire problem
and not due to a variation between
gauges. While
tubeless tires have some
ability to self-seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure.
Even
though your vehicle is
equipped with TPMS, we
recommend that you visually check
your tires every day. If you think a
tire might be low, check it
immediately with a tire gauge.
Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose one to two psi (10
to 20 kPa, 0.1 to 0.2 kgf/cm ) per
month. Remember to check the
sparetireatthesametime.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours, or driven less than 1 mile (1.6
km).
Add or release air, if needed, to
match the recommended cold tire
pressures on page . 417

It is best to replace all four tires at
thesametime.Ifthatisnotpossible
or necessary, replace the two front
tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling. Wheels:
Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire’s sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a different
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently. If
you ever need to replace a wheel,
make sure the wheel’s specifications
match those of the original wheel
that came on your vehicle.
Replacement wheels are available at
your Acura dealer. Tires:

There are no snow tires compatible
with the PAX system, and not all tire
ch ains are suitable for use on the
PAX system tires. To prevent tire
chain damage to the PAX system
tires or wheels, ensure that no part
of the chain contacts the PAX
system.
If you must continue driving with a
flat tire, follow all the pro cedures
and precautions described on page
.
Never
use a tire repair agent in a
PAX system tire, and never repair
a PAX system tire by yourself.
Repair or replacement must be
done by an Acura dealer or an
authorized Michelin PAX system
dealer.
Your
vehicle is equipped with the
Michelin PAX system which,
together with the tire pressure
monitoring system (TPMS), enables
you to continue driving even if one or
more of your tires loses its pressure.
The tires and wheels on your vehicle
are speci ally designed for the PAX
system, and the PAX system is
specifically designed and fine-tuned
foryourvehicle.
Because of these reasons, use only
the wheels and tires designated in
this owner’s manual. Never mix PAX
system wheels or tires with
conventional wheels or tires. Do
not replace the PAX system tires
and wheels with conventional tires
andwheels.Doingsowoulddisable
the PAX system and the tire
pressure monitoring system (TPMS),
and may void your new vehicle
warranty. If you mount snow chains on you
tires, use the chains recommended
by Acura (see page ). 420

Your vehicle is equipped with the
Mich elin PAX system. Since each
Mi chelin PAX system tire has an
inner support ring that allows it to
continue running without air, it may
be diffi cult to immediately judge
from 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 first detection of
a flat tire.
If the indicator and the message
come on again, you proba bly have a
flat tire. In this case, you will see a
‘‘PAX SYSTEM WARNING’’
message on the multi-information
display.
The
TPMS monitors the air pressure
of all four 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
indicator in the instrument panel and
a ‘‘CHECK TIRE PRESSURE’’
message on the multi-information
display. If the indicator and the
warning message do not come on
again after you inflate 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.

Each tire, including the spare (if
provided), should be checked
monthly when cold and inf lated to
the inf lation pressure recommended
by the vehicle manuf acturer on the
vehicle placard or tire inf lation
pressure label.
(If your vehicle has tires of a
dif f erent size than the size indicated
on the vehicle placard or tire
inf lation pressure label, you should
determine the proper tire inf lation
pressure f or 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
signif icantly under-inf lated.
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 signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect 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-inf lation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
