Auto-ReverseThe power tailgate has an auto-
reverse feature. If it meets resistance
while opening or closing, it will beep
three times and reverse direction.
However, the tailgate may not
reverse immediately. Always make
sure passengers and objects are clear
of the tailgate before opening or
closing it.
Closing a power tailgate while
anyone is in the path of the
tailgate can cause serious
injury.
Make sure everyone is clear
before closing the power
tailgate.Also check that passengers,
especially children, do not have their
hands on the edge of the tailgate or
on the tailgate sill. The auto reverse
feature stops working when the
tailgate is about to latch so the motor
can pull the tailgate shut.
If your vehicle's battery is
disconnected, goes dead, or the fuse
is removed while the tailgate is fully
open, the power tailgate needs to be
reset. After connecting the battery or
installing the fuse, close the tailgate
fully by hand.
The power tailgate may not open or
close under the these conditions:
●The vehicle is parked on a steep
hill.●When the vehicle is swayed in a
strong wind.
●When the tailgate or the roof is
covered with snow or ice.
Do not install any accessories on the
tailgate. It may cause the tailgate to
malfunction. If there is snow or ice
on the tailgate, make sure to remove
it before you operate the tailgate.
If you push the tailgate release
button inside the handle while the
tailgate is opening or closing, it will
stop moving. You need to open or
close it the rest of the way manually.
The tailgate has sensors on both
sides. Be careful not to damage
them. If the sensors are damaged,
the power tailgate does not function
properly.

Your vehicle's audio system may
disable itself if it is disconnected
from electrical power for any reason.
To make it work again, you must
enter a specific five-digit code with
the preset buttons. Because there are
hundreds of number combinations
possible from the five digits, making
the system work without knowing
the exact code is nearly impossible.
You should have received a card that
lists your audio system code number
and serial number. It is best to store
this card in a safe place at home. In
addition, you should write the audio
system's serial number in this
owner's manual.
If you lose the card, you must obtain
the code number from your dealer.
To do this, you will need the audio
system's serial number.NOTE:
In the U.S., if you have a My
Acura account, you can retrieve the
anti-theft code online.
If your vehicle's battery is
disconnected or goes dead, the audio
system will disable itself. If this
happens, you will see ‘‘ENTER
CODE ’’in the frequency display (on
the display on models with
navigation system) the next time you
turn on the system. Use the preset
buttons to enter the five-digit code.
The code is located on the radio code
card included in your owner's
manual kit. When it is entered
correctly, the radio will start playing.
If you make a mistake entering the
code, do not start over; complete the
five-digit sequence, then enter the
correct code. You have 10 tries to
enter the correct code. If you are
unsuccessful in 10 attempts, you
must then leave the system on for 1
hour before trying again. The system will retain your AM and
FM presets even if power is
disconnected.Radio Theft Protection37409/10/28 17:15:37 10 ACURA ZDX KA KC New North America Own 50 31SZN600 enu

Your vehicle's starting system has an
auto control mode. When you have
your keyless access remote and push
the engine start/stop button while
depressing the brake pedal, this
feature keeps the engine's starter
motor running until the engine
starts.
Follow these instructions to start the
engine:1. Apply the parking brake.
2. In cold weather, turn off all electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in Park. Press on the brake pedal.
In either of the following cases, you
should insert the keyless access
remote into the keyless remote slot.
For more information, see pages 202
and 203.●The keyless access remote system
main switch is off.
●The keyless access remote battery
becomes weak or dead.
4. Without touching the accelerator pedal, push and release the engine
start/stop button. You do not need
to hold the engine start/stop
button to start the engine. The
starter motor can run for up to 9
seconds to guarantee starting
when the outside temperature is
very low.
If you hold the engine start/stop
button for more than 7 seconds,
the starter motor, depending on
the outside temperature, runs for
up to 25 seconds until the engine
starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
The immobilizer system protects your
vehicle from theft. If an improperly
coded keyless access remote (or other
device) is used, the engine's fuel system
is disabled. For more information, see
page 149.The engine is harder to start in cold
weather. Also, the thinner air found at
altitudes above 8,000 feet (2,400
meters) adds to this problem.

The sensor on the negative terminal
monitors your vehicle's battery
condition.
If there is a problem with the sensor,
you will see a‘‘CHECK BATTERY
SENSOR’’ message on the multi-
information display. Have the vehicle
checked by your dealer.
Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a cloth
or paper towel. Coat the terminals
with grease to help prevent further
corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician. WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle's
electrical system. Always disconnect
the negative (－ ) cable first, and
reconnect it last.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.
If your vehicle's battery is
disconnected or goes dead, the audio
system may disable itself. The next
time you turn on the radio, you will
see ‘‘ENTER CODE ’’in the
frequency display. Use the preset
buttons to enter the code (see page

If this indicator comes on
while driving, it means one
of the engine's emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle's performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fuel fill cap. You will also see a
‘‘ TIGHTEN FUEL CAP ’’message on
the multi-information display.
Tighten the cap until it clicks at least
once. Tightening the cap will not turn
the indicator off immediately; it can
take several days of normal driving. If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have your vehicle
checked by the dealer as soon as
possible.
If you keep driving with the malfunction
indicator lamp on, you can damage
your vehicle's emissions controls and
engine. Those repairs may not be
covered by your vehicle's warranties.
You will also see a
‘‘CHECK
EMISSION SYSTEM ’’message on
the multi-information display (see
page 90).
Readiness CodeYour vehicle has certain ‘‘readiness
codes ’’that are part of the on-board
diagnostics for the emissions systems.
In some states, part of the emissions
testing is to make sure these codes are
set. If they are not set, the test cannot
be completed.
If the battery in your vehicle has been
disconnected or gone dead, these
codes may be erased. It takes several
days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition switch to the ON (II) position
(set ON mode on models with keyless
access system), without starting the
engine. The malfunction indicator lamp
will come on for 20 seconds. If it then
goes off, the readiness codes are set. If
it blinks five times, the readiness codes
are not set. If possible, do not take your
vehicle for an emissions test until the
readiness codes are set. Refer to
Emissions Testing for more
information (see page 619).Malfunction Indicator Lamp

Testing of Readiness Codes
If you take your vehicle for an
emissions test shortly after the
battery has been disconnected or
gone dead, it may not pass the test.
This is because of certain‘‘readiness
codes ’’that must be set in the on-
board diagnostics for the emissions
systems. These codes are erased
when the battery is disconnected,
and set again only after several days
of driving under a variety of
conditions. If the testing facility determines that
the readiness codes are not set, you
will be requested to return at a later
date to complete the test. If you must
get the vehicle retested within the
next two or three days, you can
condition the vehicle for retesting by
doing the following.
1. Make sure the gas tank is nearly,
but not completely, full (around
3/4).
2. Make sure the vehicle has been parked with the engine off for 6
hours or more.
3. Make sure the ambient temperature is between 40° and
95°F (4° and 35°C). 4. Without touching the accelerator
pedal, start the engine, and let it
idle for 20 seconds.
5. Keep the vehicle in Park. Increase the engine speed to 2,000 rpm, and
hold it there until the temperature
gauge rises to at least 1/4 of the
scale (about 3 minutes).
6. Without touching the accelerator pedal, let the engine idle for 20
seconds.
