sensor Acura RDX 2007 Owner's 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. 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
thetirepressure monitor(seepage

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.

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
qualified technician.
Your vehicle has a tire pressure
monitor on the info rmation display. The
tire pressure monitor uses the
same display as the door and tailgate
open monitor. When any of the tires
has low pressure, the low tire
pressure indicator on the instrument
panel comes on, and you will also see
which tire is losing the pressu re on
the tire pressure monitor.
If the TPMS indicator comes on, the
tire pressure monitor does not work
(see page ).
If the low tire pressure indicator and
the low tire position on the low tire
pressure monitor do not go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible. 73

If your seat belts get dirty, use a sof t
brush with a mixture of mild soap
and warm water to clean them. Do
not use bleach, dye, or cleaning
solvents. Let the belts air-dry bef ore
you use the vehicle.
Dirt build-up in the loops of the seat
belt anchors can cause the belts to
retract slowly. Wipe the insides of
the loops with a clean cloth
dampened in mild soap and warm
water or isopropyl alcohol.The driver’s f loor mat that came
with your vehicle hooks over the
f loor mat anchors. This keeps the
f loor mat f rom sliding f orward and
possibly interf ering with the pedals.
If you remove the driver’s f loor mat,
make sure to re-anchor it when you
putitbackinyourvehicle.A non-Acura f loor mat may not f it
your vehicle properly. This could
prevent the proper operation of the
f olding rear seats and the passenger’s
seat weight sensors. We recommend
using genuine Acura f loor mats. Do
not put additional f loor mats on top
of the anchored mat.

The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa-
tion.
The exhaust emissions controls
include three systems: PGM-FI,
ignition timing control, and three
way catalytic converter. These three
systems work together to control the
engine’s combustion and minimize
the amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.
The PGM-FI system uses sequential
multiport f uel injection.
It has three subsystems: air intake,
engine control, and f uel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
f uel to inject under all operating
conditions.
This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.The emissions control systems are
designed and certif ied to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura replacement parts or their
equivalent f or repairs. Using lower
qualitypartsmayincreasethe
emissions f rom your vehicle.
