2010 ACURA ZDX Owners 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.

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.

Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The emergency
brake assist system increases the
stopping force when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you.Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
Braking System Design
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Brake Wear Indicators
All four brakes have audible brake
wear indicators.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal for
the brakes to occasionally squeal or
squeak when you apply them.

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.

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 594. 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.

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.
