inflation pressure Acura RDX 2007 Owner's Manual

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. Al
though your tire pressure is
monito red, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when cold, and
set to the recommended inflation
pressure as specified on the vehicle
placard and in the owner’s manual
(see page ).
Driving on a signifi cantly 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.
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.
With this indicator on, you will see
which tire is losing the pressu re on
the multi-information display along
with a ‘‘CHECK TIRE PRESSU RE’’
message (see page ).
With
this indicator on, you will see
which tire is losing the pressu re on

Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexp ectedly.
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
overinflated.
Refer to page for tire inflation
guidelines. This
indicator comes on and stays on
if there is a problem with the tire
pressure monitoring system.
If this happens, the system will shut
off and no longer monitor tire
pressures. Have the system checked
by your dealer as soon as possible. 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 ).
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.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

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 from corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stiff
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a soft brush or sponge. 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. 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
hazards, and wear unevenly.

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
