display Acura ZDX 2012 Owner's Manual

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.

Tire Pressure Monitoring System (TPMS)49209/10/28 17:15:37 10 ACURA ZDX KA KC New North America Own 50 31SZN600 enu

If there is a problem with the TPMS,
the tire pressure monitor shows a
‘‘TPMS 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 490).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 509). 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 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.

The anti-lock brake system (ABS)
helps prevent the wheels from
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the front-to-rear
braking distribution according to
vehicle loading.You should never pump the brake pedal.Let the ABS work for you by always
keeping firm, steady pressure on the
brake pedal. This is sometimes
referred to as‘‘stomp and steer. ’’You will feel a pulsation in the brake
pedal when the ABS activates, and
may hear some noise. This is normal:
it is the ABS rapidly pumping the
brakes. On dry pavement, you will
need to press on the brake pedal
very hard before the ABS activates.
However, you may feel the ABS
activate immediately if you are trying
to stop on snow or ice.
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 90).
If the indicator comes on while
driving, test the brakes as instructed
on page 594.

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.).

You will also see a‘‘CHECK VSA
SYSTEM ’’message on the multi-
information display if there is a
problem with the VSA system.
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 button. If
this happens, you cannot turn the
VSA system off by pressing the VSA
OFF button again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement. VSA OFF Button
This button is under the driver's side
vent. To turn the VSA system on and
off, press and hold it until you hear a
beep.
When VSA is off, the VSA OFF
indicator comes on as a reminder.
Press and hold the button again. It
turns the system back on.VSA is turned on every time you start
the engine, even if you turned it off
the last time you drove the vehicle.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or fresh snow, it may be easier
to free it with the VSA temporarily
switched off. When the VSA system
is off, the traction control system is
also off. You should only attempt to
free your vehicle with the VSA off if
you are not able to free it when the
VSA is on.
Immediately after freeing 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.
