2009 Acura RL TPMS

If there is a problem with the TPMS,
the multi-information display shows
a ‘‘CHECK TPMS SYSTEM’’
message.If you see this message, the tire
pressure monitor shows a ‘‘SYSTEM
FUNCTION ERROR’’ message. The
system may not be able to detect or
signal low tire pressure as intended.
Also, the tire pressure readings will
not be displayed. Have your vehicle
checked by a dealer as soon as
possible.
Also, the low tire pressure/TPMS
indicator begins to f lash (see page
).
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/
TPMS 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.

If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
When VSA is off, the VSA activation
indicator comes on as a reminder.
Press and hold the switch again. It
turns the system back on.
This switch is at the right side of the
lef t vent. Press and hold it until you
hear a beep.
Immediately af ter f reeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system
is of f , the traction control system is
alsooff.Youshouldonlyattemptto
f ree your vehicle with the VSA of f if
you are not able to f ree it when the
VSA is on.
If the low tire pressure/TPMS
indicator comes on (see page ),
or the multi-information display
shows a ‘‘CHECK TPMS SYSTEM’’
message with the indicator flashing
(see page ), the VSA system
automatically turns on even if the
VSA system is turned off with the
VSA OFF switch. In this case, you
cannot turn the VSA system of f by
pressing the VSA OFF switch again. 429

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 af f ect handling and f uel
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.
Thetirepressuremonitoringsystem
(TPMS)willwarnyouwhenatire
pressure is low. See page f or
inf ormation 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.
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.
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 f rom corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stif f
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a sof t brush or sponge.

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
owner’s manual regarding tire
inflation and maintenance.

If you check the pressure when the
tires are hot [driven f or several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3to
0.4 kgf /cm ) higher than the cold
reading. This is normal; do not
release air to match the cold
pressure. The tires will be
underinf lated.
Youshouldgetyourowntire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.While tubeless tires have some
ability to self -seal if they are
punctured, you should look closely
f or punctures if a tire starts losing
pressure.
Even though your vehicle is
equipped with 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.
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 one to two psi (10
to 20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime.
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).
Add or release air, if needed, to
match the recommended cold tire
pressures on page .

It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.Wheels:
Tires:
See page f or DOT tire quality
grading inf ormation, and page
f or tire size explanation.
Also be sure you use only TPMS
specif ic wheels. If you do not, the
tire pressure monitoring system will
notworkonthattire.
If you ever need to replace a wheel,
make sure the wheel’s specif ications
match those of the original wheel
that came on your vehicle.
Replacement wheels are available at
your Acura dealer. 528

Installing improper tires on your
vehicle can affect handling and
stability. This can cause a crash
in which you can be seriously
hurt or killed.
Always use the size and type of
tires recommended in this
owner’s manual.

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or replaced,
and put it back on your vehicle as
soon as you can.
Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
samewheel.Thesparetireisnot
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
Do not mount snow chains on the
compact spare tire.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
Follow these precautions:
Never exceed 50 mph (80 km/h).
This tire gives a harsher ride and
less traction on some road
surf aces. Use greater caution
while driving.
After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
Af ter several miles (kilometers)
driving with the spare, this
indicator begins to f lash, then
stays on again. You will also see a
‘‘CHECK TPMS SYSTEM’’
message on the multi-inf ormation
display (see page ). 433
