sensor Acura MDX 2005 User Guide

Improperly replacing
or covering f ront seat-back covers
can prevent your side airbags f rom
inf lating during a side impact.
Together, airbags and
seat belts provide the best
protection.
Tampering could cause
the airbags to deploy, possibly
causing very serious injury.
This could make the
driver’s seat position sensor or the
f ront passenger’s weight sensors
inef f ective. If it is necessary to
remove or modif y a f ront seat to
accommodate a person with
disabilities, f irst contact Acura
Client Services at 800-382-2238.
Even if your
airbags do not inflate, your dealer
should inspect the driver’s seat
position sensor and the f ront
passenger’s weight sensors to
make sure they are operating
properly.

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 and the
appropriate tire on the tire pressure
monitor to come on. 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.When the tire pressure monitoring
system warning light is lit, one or
more of your tires is signif icantly
under-inf lated. You should stop and
check your tires as soon as possible.
If you think you can saf ely drive a
short distance to a service station,
proceed slowly, and inf late the tire to
the recommended pressure shown
on the driver’s doorjamb.
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.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.
Although your tire pressure is
monitored, each tire should be
checked monthly, including the
spare.
Check the pressure with the tires
cold, af ter the vehicle has been
parked f or at least 2 hours.
Set to the recommended inf lation
pressure as specif ied on the vehicle
placard and in the owner’s manual
(see page ).

The appropriate tire indicator and
low tire pressure indicator comes on
if a tire becomes signif icantly
underinf lated. Follow the
instructions under ‘‘Low Tire
Pressure Indicator’’.The indicator comes on and stays on
if there is a problem with the tire
pressure monitoring system.
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.
If this happens, the system will shut
of f and no longer monitor tire
pressures. Have the system checked
by your 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 specif ic wheels. It is
recommended that you always have
your tires serviced by your dealer or
qualif ied technician.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

dealer as soon as possible.
If you have a f lat tire, the low tire
pressure and tire monitor indicators
will come on. Replace the indicated
flat tire with the compact spare tire
