2010 ACURA ZDX sensor

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 579).
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.

Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).
Models equipped with the keyless
access system have an engine start/
stop button instead of an ignition
switch. ON mode is the equivalent of
ON (II). See page 196 for ignition
switch and power mode comparison.
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 and each tire
pressure to warn you about the low
tire pressure when you select the
display by pressing the INFO button
several times.

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 579).
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.
If the low tire pressure/TPMS
indicator and the low tire position on
the low tire pressure monitor do not
go out after inflating the tires to the
specified values, have your dealer
check the system as soon as
possible.

OverviewIf equippedThe collision mitigation braking
system™(CMBS ™) can assist you
when there is a possibility of your
vehicle hitting the vehicle in front of
you. It is designed to reduce the
speed of your vehicle before an
unavoidable collision occurs and, if
possible, to alert you to a potential
collision while there is time to
prevent it. Here is a brief description
of what the CMBS can do:●When your speed is above 10 mph
(16 km/h), the CMBS radar
sensor in the front grille can sense
a vehicle ahead of you. When your
vehicle gets too close to the
vehicle ahead of you, the system
may activate a warning beep,
causing automatic application of
the brakes, and causing the e-
pretensioners to tighten the front
seat belts (see page 24).
●The CMBS does not activate if the
speed difference between the two
vehicles is less than 10 mph (16
km/h). CMBS may also not
activate if you turn the steering
wheel to avoid the collision.
When the CMBS activates, the brake
lights also come on.
The CMBS consists of a radar sensor
in the front grille, a brake actuator in
the engine compartment, an
indicator on the instrument panel,
seat belt e-pretensioners on the front
seats, and an on/off switch under the
driver's side vent.RADAR SENSOR

Radar SensorThe radar sensor cover 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. If either of these parts receives a
strong impact, to turn off the system,
press and hold the CMBS off switch
until you hear a beep, 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 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.

The radar sensor may not always
scan as intended. Here are 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 Cargoon page 465), and
do not make any modifications to
the suspension (see Accessories
and Modifications on page 463).●The tires are not correctly
maintained. Always make sure the
tire pressures are correct (see
page 568), and that the tires are
the correct size and in good
condition (see Tires on page 567). Collision Alarm
If the system senses a likely collision
with a vehicle or object ahead of you,
it alerts you with an audible and a
visual alarm.
The audible alarm is a constant
beeping sound; the visual alert is an
amber colored BRAKE message that
flashes on the multi-information
display. If these alarms come on,
take the appropriate means to
prevent a collision (apply the brakes,
change lanes, etc.).

CMBS OFF ButtonTo turn the CMBS off, press the
CMBS OFF button under the driver's
side vent for about 1 second. When
you do this, a beeper sounds, a
CMBS indicator on the instrument
panel comes on, and a CMBS OFF
message appears on the multi-

system back on, press the button
again for about 1 second.When you select the ON mode by
operating the engine start/stop

Automatic Shut Off
Any of the conditions below can
cause the CMBS to shut off. When
the system shuts off, the CMBS
indicator in the instrument panel
comes on, and a CHECK CMBS
SYSTEM message appears on the
multi-information display for about 5
seconds.
●An abnormal tire condition is
detected (wrong tire size, flat tire,
etc.).●Extended off-road or mountainous
