2007 Acura RL tire pressure

When the CMBS is on, the radar
sensor constantly scans for vehicles
ahead of you. This means that
driving on a ro ad with a few or no
vehicles could cause a CHECK
CMBS RADAR SENSOR message to
appear on the multi-information
display. This is normal and not a
cause for concern. The
radar sensor may not always
scan as intended. Here are two
examples:
Thetiresarenotcorrectly
maintained. Always make sure the
tire pressures are correct (see
page ), and that the tires are
the correct size and in good
condition (see Tires on page ).
Your
vehicle is tilted because of a
heavy load in the rear or from
modifications to the suspension.
Do not overload your vehicle (see
Carrying Cargo on page ), and
do not make any modifi cations to
the suspension (see Accessories
and Modifications on page ).

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.
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 in the
instrumental panel and the
appropriate tire position indicator on
thetirepressuremonitoronthe
multi-info rmation display (see page
)tocomeon. 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.
When
the low tire pressure indicator
is on, one or more of your tires is
signifi cantly underinflated. The
multi-information display also shows
a ‘‘CHECK TIRE PRESSURE’’
message (see page ). You should
stop and check your tires as soon as
possible, and inflate them to the
proper pressu re as indicated on the
vehicl e’s tire information placard.
Driving on a significantly 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.
Becausetirepressure variesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly. Refer to page for tire inflation
guidelines.

Although your tire pressure is
monitored, you must manually check
thetirepressuresmonthly. If
you have a flat tire, the low tire
pressu re and tire monitor indicators
will come on. Replace the indicated
flat tire with the compact spare tire
(see page ).
Each
tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inflation pressure as
sp ecified on the vehicle placard and
intheowner’smanual(seepage ). 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.
Havetheflattirerepairedbyyour
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
a qualif ied technician.
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. If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure. 415

If any of the tires have low pressure,
the multi-information display will
show a ‘‘CHECK TIRE PRESSURE’’
message. You will also see one or
more low pressure tire positions
blinking in the display (see page
).
If
there is a system error with the
TPMS, the multi-info rmation display
showsa‘‘SYSTEMFUNCTION
ERROR’’ message (see page ),
and the tire pressure readings will
not be displayed. You will also see a
‘‘CHECK TPMS SYSTEM’’ message
on the multi-information display (see
page ).
When
all tire pressures are normal,
the multi-information display will
show ‘‘TIRE PRESSURE OK
SYSTEM FUNCTION NORMAL.’’
When any of the tires has low
pressure, the multi-info rmation
display shows a ‘‘TIRE PRESSURE
ERROR SYSTEM FUNCTION
NORMAL’’ message (see page ).

If one or more tires have low
pressure, the low tire pressure
indicator on the instrument panel
also comes on (see page ).
When cruise control is on while
driving, the pressure reading cannot
be checked by the tire pressure
monitor on the multi-inf ormation
display.
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.
When the TPMS is functioning
normally, you can see the tire
pressure readings of each tire in psi
(U.S. models) or kPa (Canadian
models) by pressing the SEL/
RESET button while the multi-
inf ormation display shows the tire
pressure monitor. 365

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
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 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.

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surfaces. It does this
by regulating the engine’s output and
by selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. You will also see
the VSA activation indicator blink.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety. When
VSA activates, you will see the
VSA activation indicator blink (see
page ).
If this indicator comes on while
driving, pull to the side of the road
when it is safe, and turn off the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on, or comes
back on while driving, have the VSA
system inspected by your dealer.
If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehic le as
soon as possible (see page ). Wh
en the VSA system indicator
comes on, you will also see a
‘‘CHECK VSA SYSTEM’’ message
on the multi-information display.
Without VSA, your vehicle still has
normal braking and cornering ability,
but it does not have VSA traction and
stability enhancement.
If the low tire pressure indicator
comes on (see page ), or the
multi-info rmation display shows a
‘‘CHECK TPMS SYSTEM’’ message
(see page ), the VSA system
automatically turns on even when
the VSA system is turned of f with
the VSA OFF switch. In this case,
you cannot turn the VSA system of f
by pressing the VSA OFF switch
again.
