2011 Acura MDX display

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/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.
Low Tire Pressure/
TPMS Indicator
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is significantly underinflated.
You should stop and check your tires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle's tire information
placard.
It is possible that the pressures
shown on the multi-information
display and the pressures you
manually measure are slightly
different.
If the difference is significant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-information display go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible. If you think you can safely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
If the tire is flat, or if the tire pressure
is too low to continue driving, replace
the tire with the compact spare tire
(see page 545).
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.

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/
TPMS indicator to come on. Or, if
you check and adjust your tire
pressure in cooler conditions, and
drive into extremely hot conditions,
the tire may become overinflated.
However, the low tire pressure/
TPMS indicator will not come on if
the tires are overinflated.
Refer to page 534 for tire inflation
guidelines.
If there is a problem with the TPMS,
this indicator begins to flash. It stops
flashing after approximately 1
minute, then stays on. You will also
see a‘‘CHECK TPMS SYSTEM ’’
message on the multi-information
display (see page 87). Although your tire pressure is
monitored, you must manually check
the tire pressures monthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inflation pressure as
specified on the vehicle placard and
in the owner's manual (see page
535).
Tire Pressure Monitor
To select the tire pressure monitor,
press the INFO button several times
with the ignition switch in the ON
(II) position.
You will see the above display on the
multi-information display when all
tire pressures are normal.

To see the inflation pressures of all
four tires, press the SEL/RESET
button. The display changes as
shown above.
Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).
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/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.

If any of the tires has low pressure,
the tire pressure monitor also shows
the above message to warn you
about the low tire pressure when you
select the display by pressing the
INFO button several times.
Following this display, press the
SEL/RESET button to see each tire
pressure. When you continue driving
after installing the spare tire, you will
also see this message on the multi-
information display.
If there is a problem with the TPMS,
the tire pressure monitor shows a
‘‘SYSTEM FUNCTION ERROR ’’
message and the tire pressure
readings are not displayed. If this
happens, you will first see a system
warning message ‘‘CHECK TPMS
SYSTEM ’’on the multi-information
display. TPMS System Failure
If there is a problem with the TPMS,
you will see the above message on
the multi-information display.
If you see this message, the system
is off and is not monitoring the tire
pressures. Have the system checked
by your dealer as soon as possible.
Also, the low tire pressure/TPMS
indicator begins to flash, then stays
on (see page 449).

If the low tire pressure/TPMS
indicator comes on, or the multi-
information display shows a‘‘CHECK
TPMS SYSTEM ’’message, the VSA
system automatically turns on even
when the VSA system is turned off
by pressing the VSA OFF switch
(see page 468). If this happens, you
cannot turn the VSA system off by
pressing the VSA OFF switch again.
When you restart the vehicle with
the compact spare tire, the TPMS
system message will also be
displayed on the multi-information
display after several miles
(kilometers) driving.
Changing a Tire with TPMS
If you have a flat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated flat tire with the compact
spare tire (see page 545). After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. After several miles
(kilometers) driving, this indicator
begins to flash, then stays on again.
You will also see a
‘‘CHECK TPMS
SYSTEM ’’message on the multi-
information display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
spare tire pressure to be sure it is
correct. This indicator and the warning
message on the multi-information
display will go off, after several miles
(kilometers) driving, when the spare
tire is replaced with the specified
regular tire equipped with the tire
pressure monitor sensor.
Each wheel is equipped with a tire
pressure sensor. You must use
TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualified technician.
Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Have the flat tire repaired by your
dealer as soon as possible.

ABS Indicator
If this indicator comes on, the anti-
lock function of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.
You will also see a ‘‘CHECK ABS
SYSTEM ’’message on the multi-
information display (see page 87).
If the indicator comes on while
driving, test the brakes as instructed
on page 558. If the ABS indicator and the brake
system indicator come on together,
and the parking brake is fully
released, the EBD system may also
be shut down.
Test your brakes as instructed on
page 558. If the brakes feel normal,
drive slowly and have your vehicle
repaired by your dealer as soon as
possible. Avoid sudden hard braking
which could cause the rear wheels to
lock up and possibly lead to a loss of
control.
Important Safety Reminders
ABS does not reduce the time or
distance it takes to stop the
vehicle.
It only helps with steering
control during braking.
ABS will not prevent a skid that
results from changing direction
abruptly, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather
conditions.
ABS cannot prevent a loss of
stability. Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road.
A vehicle with ABS may require a
longer distance to stop on loose or
uneven surfaces, such as gravel or
snow, than a vehicle without anti-
lock.

Radar SensorThe radar sensor is located under the
Acura emblem in the front grille. If
the radar sensor cover is covered
with mud, dirt, dead leaves, wet
snow, etc., or if you put a sticker on
it, the CMBS will automatically shut
off, and the CMBS indicator on the
instrument panel will come on. You
will also see a‘‘CHECK CMBS
RADAR SENSOR ’’message on the
multi-information display for about 5
seconds.
Always keep the radar sensor cover
clean. If it gets dirty, clean it with
water or a mild detergent. Never use
chemical solvents or polishing
powder.
There are three bolts on the sides of
the radar sensor. Do not tamper with
these bolts, or you may cause the
system to malfunction. Do not allow anything to impact the
radar sensor or the radar sensor
cover. If either of these parts receives
a strong impact, switch the system
off by pressing the CMBS off button,
and have your vehicle checked by a
dealer. If the front grille ever needs
to be repaired, consult a dealer first.
If the radar sensor cover or the radar
sensor ever needs to be removed,
take your vehicle to a dealer.
When the CMBS is on, the radar sensor
constantly scans for vehicles directly
ahead of you. This means that driving
on a road 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.

Certain conditions may cause the
radar aim to be temporarily out of
proper range, such as the following
two examples:●
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 428), and
do not make any modifications to
the suspension (see Accessories
and Modifications on page 426).
●
The tires are not correctly
maintained. Always make sure the
tire pressures are correct (see
page 534), and that the tires are
the correct size and in good
condition (see Tires on page 534).Collision Alert
If the system senses a likely collision
with a vehicle or object ahead of you,
it alerts you with a visual alert or a
combination of a visual alert and an
audible alert.
The visual alert is an amber colored
BRAKE message that flashes on the
multi-information display, the audible
alert is a constant beeping sound. If
one or more of the alerts come on,
take the appropriate means to
prevent a collision (apply the brakes,
change lanes, etc.).
