This indicator normally comes on f or

ignition to ON (II).
This indicator normally comes on f or
a f ew seconds when you turn the
ignition to ON (II).
If it comes on while driving, it
indicates that one or more of your
vehicle’s tires are extremely low on
pressure.
If this happens, pull to the side of the
road when it is saf e, check which tire
has lost the pressure on the Tire
Pressure Monitor, and determine the
cause. If it is because of a f lat tire,
replace the flat tire with the compact
spare (see page ), and have the
f lat tire repaired as soon as possible.
If two or more tires are underinf lated,
call a prof essional towing service
(see page ). Ref er to page
f or more inf ormation. The appropriate tire indicator will
come on along with the Low Tire
Pressure Indicator if a tire is
extremely under inf lated or has
suddenly lost pressure. See Low Tire
Pressure Indicator f or what to do if
this indicator comes on.
If this indicator comes on and stays
on at any other time, or it does not
come on when you turn the ignition
switch to ON (II), there is a problem
with the TPMS. With this indicator
on, the low tire pressure indicator
and the tire pressure monitor will not
come on when a tire loses pressure.
Take the vehicle to your dealer to
have the system checked.

Your Acura 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 and the
appropriate tire on the Tire Pressure
Monitor to come on.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.
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,
and inflate them to the proper
pressureasindicatedonthevehicle’s
tire inf ormation placard. Each tire, including the spare should
be checked monthly when cold and
set to the recommended inf lation
pressure as specif ied in the vehicle
placard and owner’s manual (see
page ).
Although your tire pressure is
monitored, you must manually check
thetirepressuresmonthly.
If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station and
inflate 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.

The appropriate tire indicator and
Low Tire Pressure Indicator will
come on if a tire becomes
signif icantly underinf lated. Follow
the instructions under ‘‘Low Tire
Pressure Indicator’’.The indicator comes on and stays on
when there is a problem with the
Tire Pressure Monitoring System.
If this happens, the system will shut
of f and no longer monitor tire
pressures. Have the system checked
by an Acura 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
(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 Acura
dealer or qualif ied technician.
Af ter you replace the f lat tire, the
Low Tire Pressure indicator will stay
on.Thisisnormal;thesystemisnot
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.

To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.
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.Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.
Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to f ail
f rom being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,aremore
prone to damage from road hazards,
and wear unevenly.Use a gauge to measure the air
pressure at least once a month. Even
tires that are in good condition may
lose one to two psi (10 to 20 kPa, 0.1
to 0.2 kgf /cm ) per month.
Remember to check the spare tire at
thesametime.
Add or release air, if needed, to
match the recommended cold tire
pressures on page .
The Tire Pressure Monitoring
System (TPMS) will warn you when
a tire pressure is low. See page
f or inf ormation on the 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. 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).
