2007 Acura RL tires

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.

Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
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.
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.
This switch is at the right side of the
lef t vent. Press it to turn VSA on and
off.
When VSA is off, the VSA activation
indicator comes on as a reminder.
VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.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.

Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don’t,
you should install special mirrors if
you cannot clearly see behind you, or
if the trailer creates a blind spot.

driving away, be sure to check the
f ollowing:
The vehicle has been properly
serviced, and the tires, brakes,
suspension, cooling system, and
lights are in good operating
condition.
All items in or on the trailer are
properly secured and cannot shif t
