tire pressure Acura TSX 2007 User Guide

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 significantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator to come on. Although
your tire pressure is
monitored, 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 ).
Driving on a significantly under-
inflated tire causes the tire to
ov erheat and can lead to tire failure.
Under-infl ation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability. When
the low tire pressure indicator
is on, one or more of your tires is
signifi cantly underinflated. You
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure as indicated on
the vehicle’s tire information placard.
With this indicator on, you will see
which tire is losing the pressure on
the multi-inf ormation display along
with a ‘‘CHECK TIRE PRESSURE’’
message (see page ).

Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly.
For example, if you check and fill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure
indicator to come on. Or, if you
check and adjust your tire pressure
in cooler conditions, and drive into
extremely hot conditions, the tire
maybecomeoverinflated.However,
the low tire pressure indicator will
not come on if the tires are
overinf lated.
Refer to page for tire inflation
guidelines. To display the tire pressure monitor,
press the INFO button until it
appears on the multi-inf ormation
display.
When all tire pressures are normal,
the tire pressure monitor will show a
‘‘TIRE PRESSURE OK’’ message.When any of the tires have low
pressure, the tire pressure monitor
shows a ‘‘TIRE PRESSURE ERROR’’
message.

When any of the tires have low
pressure, the low tire pressure
indicator on the instrument panel
comes on, and the multi-inf ormation
display also interrupts the current
display and shows a ‘‘CHECK TIRE
PRESSURE’’ message. You can see
one or more of the low pressure tire
positions highlighted in the display
along with this message.When the TPMS is functioning
normally, you can see the tire
pressure readings of each tire in psi
(U.S. models) or kPa (Canadian
models) by pressing the SEL/
RESET button while the multi-
inf ormation display shows the tire
pressure monitor.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.

Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Havetheflattirerepairedbyyour
dealer as soon as possible.
Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualified technician.
After
you replace the flat tire with
the spare, 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.
If
you have a flat tire, the low tire
indicator and tire pressure monitor
will come on. Replace the indicated
flat tire with the compact spare tire
(see page ).
If there is a problem with the TPMS,
the multi-information display shows
a ‘‘CHECK TPMS SYSTEM’’
message.

If you see this message, the tire

Also, the tire pressure readings will
not be displayed. Have your vehicle
checked by a dealer as soon as
possible.

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.
To
safely operate your vehicle, your
ti res must be the proper type and
size, in good condition with adequate
tread, and correctly inflated.
The following pages give more
detailed information on how to take
care of your tires and what to do
when they need to be replaced.

Clean the wheels as you would the

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
owner’s manual regarding tire
inflation and maintenance.

The following charts show the
recommended cold tire pressures for
most normal and high-speed driving
conditions.
For additional information about
your tires, see page .
For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb. Thecompactsparetirepressureis:
If you check air pressures when the
tires are hot [driven f or several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3to0.4
kgf /cm ) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air pressure. The tire will be
underinf lated.
Youshoulduseyourowntire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure 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 1 to 2 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
pressure.

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 illustration 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.
