2007 Acura MDX spare tire

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.

the low tire pressure when you select
the display by pressing the INFO
button several times. Following this
display, press the SEL/RESET
button to see each tire pressure.
When you continue driving af ter
installing the spare tire, you will also
see this message on the multi-

If there is a problem with the TPMS,
you will see the above message on
the multi-information display.
If you see this message, the system
is of f and is not monitoring the tire
pressures. Have the system checked
by your dealer as soon as possible.

(kilometers).
If you have a flat tire, the low tire
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 towing a trailer, we
recommend that you carry a full-size
spare wheel and tire for your vehicle
and trailer. See page for proper
tire size, page f or how to store a
full size wheel and tire, and page f or inf ormation on changing a
flat tire.
Remember to unhitch the trailer
bef ore changing a f lat. Ask your
trailer sales or rental agency where
and how to store the trailer’s spare
tire.
Many states and provinces require
special exterior mirrors when towing
a trailer. Even if they don’t, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot. This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it. Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but do not let the
chains drag on the ground.
Use this illustration to identif y each
terminal in the trailer brake
controller connector.

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.

Tire Size Cold Tire Pressure
for Normal Driving
Front/Rear:
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked for 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.
If you check the pressure when the
tires are hot [driven for several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3 to0.4
kgf/cm ) higher than the cold
reading. This is normal; do not
release air to match the cold
pressure. Tubeless
tires have some ability to
self-seal if they are punctu red. You
should look closely for punctu res if a
tire starts losing pressure.
Youshouldgetyourowntire
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. The
following chart shows the
recommended cold tire pressures for
most normal and high-speed driving
conditions.

For convenience, the recommended
tire sizes and cold tire pressures are
