Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator in the instrument
panel to come on. If this happens,
you will see which tire is losing
pressure on the multi-inf ormation
display along with a ‘‘CHECK TIRE
PRESSURE’’ message.When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. You
should stop and check your tires as
soon as possible, and inf late them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard.
It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure
indicator and message on the multi-
inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly. 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. If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire.

The TPMS can misinterpret the tire
pressure because of differences in
the air temperatures. For example, if
youcheckandfillyourtiresina
warm area, then drive in extremely
cold weather, the tire pressure will
be lower than measured and could
be underinflated and cause the
TPMS indicators to come on. Or, if
youcheckandadjustyourtire
pressu re in cooler conditions, and
drive into extremely hot conditions,
thetiresmaybecomeoverinflated.
However, the TPMS indicators will
not come on if the tires are
overinflated.
Refer to page for tire inflation
guidelines. Al
though your tire pressure is
monito red, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inflation pressure as
sp ecified on the vehicle placard and
intheowner’smanual(seepage ).
Toselectthetirepressuremonitor,
press the INFO button several times
with the ignition switch in the ON
(II) position.
You will see the above display on the
multi-inf ormation display when all
tire pressures are normal.

pressu re and tire monitor indicators
will come on. Replace the indicated
flat tire with the compact spare tire
(see page ). Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
qualif ied technician.
Af ter you replace the f lat tire, the
low tire pressure indicator stays on.
This is normal; the system is not
monitoring the spare tire pressure.
Manually check the spare tire
pressure to be sure it is correct.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise from the modulator. When
VSA activates, you will see the
VSA activation indicator blink. There
mayalsobesomenoisefromthe
modulator.
The
vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surfaces. It does this
by regulating the engine’s output and
by selectively applying the brakes.
If the VSA system indicator comes
on while driving, pull to the side of
theroadwhenitissafe,andturnoff
the engine. Reset the system by
restarting the engine. If the VSA
system indicator stays, or comes
back on while driving, have the VSA
system inspected by your deale r. If
the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehic le as
soon as possible.
You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
information display if there is a
problem with the VSA system.
If the low tire pressure indicator
comes on (see page ), or the
multi-info rmation display shows a
‘‘CHECK TPMS SYSTEM’’ message
(see page ), the VSA system
automatically turns on even if you
turn it of f with the VSA OFF switch.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.

To safely operate your vehicle, your
ti res must be the proper type and
size, in good condition with adequate
tread, and correctly inflated. Keeping
the tires properly inflated
provides the best combination of
handling, tread life, and riding
comfort.
Thetirepressuremonitoringsystem
(TPMS)will warnyouwhenatire
pressu re is low. See page for
inform ation 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.
Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,are
more prone to damage f rom road
hazards, and wear unevenly.
We recommend that you visually
check your tires everyday. 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 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime.

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
owner’s manual regarding tire
inflation and maintenance.

To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the diagram each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.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 dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
TheABSworksbycomparingthe
speed of the wheels. When replacing
tires, use the same size originally
supplied with the vehicle. Tire size
and construction can affect wheel
speed and may cause the system to
activate.It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.
If you ever replace a wheel, make
sure that the wheel’s specif ications
match those of the original wheels.
Also be sure you use only TPMS
specif ic wheels. If you do not, the
tire pressure monitoring system will
notworkonthattire.
Replacement wheels are available at
your Acura dealer.

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:
Follow these precautions:Do not mount snow chains on a
compact spare.
Do not use the compact spare tire
if you are towing a trailer.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
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
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
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. The low tire pressure indicator
stays on when you are driving with
thecompactsparetire.TheTPMS
indicator may also come on after
several miles (kilometers) driving.
