ignition Acura ZDX 2012 Owner's Manual

If you have a flat tire while driving,
stop in a safe place to change it.
Drive slowly along the shoulder until
you get to an exit or an area to stop
that is far away from the traffic lanes.
The vehicle can easily roll off
the jack, seriously injuring
anyone underneath.
Follow the directions for
changing a tire exactly, and
never get under the vehicle
when it is supported only by the
jack.
1. Park the vehicle on firm, level, and non-slippery ground. Put the
transmission in Park. Apply the
parking brake.
2. Turn on the hazard warning lights,and turn the ignition switch to the
LOCK (0) position. Have all
passengers get out of the vehicle
while you change the tire. Models equipped with the keyless
access system have an engine
start/stop button instead of an
ignition switch. VEHICLE OFF
(LOCK) mode is the equivalent of
LOCK (0). See page 196 for
ignition switch and power mode
comparison.

Diagnosing why the engine won't
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position or on models with keyless
access system, press the engine
start/stop button to set START mode
(see page 194):●You hear nothing, or almost
nothing. The engine's starter
motor does not operate at all, or
operates very slowly.●You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run.Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to
the START (III) position or on
models with keyless access system,
press the engine start/stop button to
set START mode (see page 194), you
do not hear the normal noise of the
engine trying to start. You may hear
a clicking sound, a series of clicks, or
nothing at all.
Check these things:
●Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
●Turn the ignition switch to the ON
(II) position or on models with
keyless access system, press the
engine start/stop button to set ON
mode (see page 194). Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
Jump Starting
on page 587.●Turn the ignition switch to the
START (III) position or on models
with keyless access system, press
the engine start/stop button to set
START mode (see page 194). If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
Emergency Towing on page 602.

If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal
connections (see page 573). You
can then try jump starting the
vehicle from a booster battery (see
page 587).
The Starter Operates Normally
In this case, the starter motor's speed
sounds normal, or even faster than
normal, when you turn the ignition
switch to the START (III) position or
on models with keyless access
system, press the engine start/stop
button to set START mode (see page
194), but the engine does not run.●Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page 70).
On models with keyless access system●Do you have your keyless access
system remote with you? The
vehicle will not start without the
remote within operating range.
The vehicle will not start without
the remote within operating range
and with the keyless access main
switch in the glove box turned on.●Are you using the proper starting
procedure? Refer to Starting the
Engine on page 475.●Do you have fuel? Check the fuel
gauge; the warning indicator may
not be working.●There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses (see
page 596). If you find nothing wrong, you will
need a qualified technician to find the
problem. See
Emergency Towing on
page 602.
NOTE: If you are unable to stop the
engine normally while in the Park
position, see Emergency Engine
Stop on page 200.
If the Engine Won't Start58609/10/28 17:15:37 10 ACURA ZDX KA KC New North America Own 50 31SZN600 enu

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

The brake system
indicator normally
comes on when you turn the ignition
switch to the ON (II) position, and as
a reminder to check the parking
brake. It will stay on if you do not
fully release the parking brake.
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.
If the brake system indicator comes
on while driving, the brake fluid level
is probably low. Press lightly on the
brake pedal to see if it feels normal. If
it does, check the brake fluid level
the next time you stop at a service
station (see page 553).
You will also see a ‘‘LOW BRAKE
FLUID ’’message on the multi-
information display (see page 90). If the fluid level is low, take your
vehicle to a dealer, and have the
brake system inspected for leaks or
worn brake pads.
However, if the brake pedal does not
feel normal, you should take
immediate action. A problem in one
part of the system's dual circuit
design will still give you braking at
two wheels. You will feel the brake
pedal go down much farther before
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
You will also see a
‘‘CHECK BRAKE
SYSTEM ’’message on the multi-
information display (see page 90). Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (see
Emergency
Towing on page 602).
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.

The primary under-hood fuse box is
on the passenger's side. The
secondary fuse box is located next to
the battery.
To open it, push the tabs as shown.Checking and Replacing Fuses
If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse.
Determine from the chart on pages
599, 600, and 601, or the diagram on
the fuse box lid, which fuse or fuses
control that device. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is
the cause. Replace any blown fuses,
and check if the device works.
1. Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are off.
Models equipped with the keyless
access system have an engine
start/stop button instead of an
ignition switch. VEHICLE OFF
(LOCK) mode is the equivalent of
LOCK (0). See page 196 for
ignition switch and power mode
comparison.
2. Remove the cover from the fusebox.
3. Check each of the large fuses in the under-hood fuse boxes by
looking through the top at the wire
inside. Removing these fuses
requires a Phillips-head
screwdriver.FUSE BLOWN

Onboard Refueling Vapor
Recovery
The onboard refueling vapor
recovery (ORVR) system captures
the fuel vapors during refueling. The
vapors are adsorbed in a canister
filled with activated carbon. While
driving, the fuel vapors are drawn
into the engine and burned off.
Exhaust Emissions Controls
The exhaust emissions controls
include four systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These four systems work
together to control the engine's
combustion and minimize the
amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate from the crankcase and
evaporative emissions control
systems.
PGM-FI SystemThe PGM-FI system uses sequential
multiport fuel injection. It has three
subsystems: air intake, engine
control, and fuel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
fuel to inject under all operating
conditions.Ignition Timing Control SystemThis system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.Exhaust Gas Recirculation (EGR)SystemThe exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manifold. Adding exhaust gas to the
air/fuel mixture reduces the amount
of NOx produced when the fuel is
burned.
Three Way Catalytic ConverterThe three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine's exhaust
to carbon dioxide (CO
2), nitrogen
(N
2), and water vapor.
Replacement Parts
The emissions control systems are
designed and certified to work
together in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Acura replacement parts or their
equivalent for repairs. Using lower
quality parts may increase the
emissions from your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more
information.
