2010 ACURA ZDX engine

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.

4. Connect the second jumper cableto the negative (－ ) terminal on
the booster battery. Connect the
other end to the engine hanger as
shown. Do not connect this jumper
cable to any other part of the
engine. 5. If the booster battery is in another
vehicle, have an assistant start that
vehicle and run it at a fast idle.
6. Start your vehicle. If the starter motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact.
7. Once the vehicle is running, disconnect the negative cable from
your vehicle, then from the
booster battery. Disconnect the
positive cable from your vehicle,
and then from the booster battery.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until everything is
disconnected. Otherwise, you may
cause an electrical short.Jump Starting58809/10/28 17:15:37 10 ACURA ZDX KA KC New North America Own 50 31SZN600 enu

The pointer of your vehicle's
temperature gauge should stay in the
midrange under most conditions. If it
climbs to the red mark, you should
determine the reason (hot day,
driving up a steep hill, etc.).
If the vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or spray
coming from under the hood.Driving with the temperature gauge
pointer at the red mark can cause
serious damage to the engine.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.1. Safely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn off all
accessories, and turn on the
hazard warning lights.
2. If you see steam and/or spray coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If
the high heat is due to
overloading, the engine should
start to cool down almost
immediately. If it does, wait until
the temperature gauge comes
down to the midpoint, then
continue driving.

4. If the temperature gauge stays atthe red mark, turn off the engine.
5. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 602).
6. If you do not find an obvious leak, check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
7. If there was no coolant in the reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the
temperature gauge, or lower,
before checking the radiator.
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
8. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off. 9. Start the engine and set the
climate control to AUTO at ‘‘Hi. ’’
Add coolant to the radiator up to
the base of the filler neck. If you
do not have the proper coolant
mixture available, you can add
plain water. Remember to have the
cooling system drained and refilled
with the proper mixture as soon as
you can.
10. Put the radiator cap back on tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see Emergency
Towing on page 602).
11. If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has gone
down, add coolant to the MAX
mark. Put the cap back on tightly.

This indicator should never
come on when the engine is
running. If it starts flashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
You will also see a ‘‘CHECK
ENGINE OIL LEVEL’’ message on
the multi-information display when
this indicator comes on.
Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn off
the engine as soon as you can safely get
the vehicle stopped. 1. Safely pull off the road, and shut
off the engine. Turn on the hazard
warning lights.
2. Let the vehicle sit for a minute. Open the hood, and check the oil
level (see page 458). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers. 3. If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page 545).
4. Start the engine, and watch the oil pressure indicator. If it does not go
out within 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
before you can continue driving
(see Emergency Towing on page
602).

If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
You will also see a ‘‘CHECK
CHARGING SYSTEM ’’message on
the multi-information display (see
page 90). Immediately turn off all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.If you see a
‘‘REPLACE BATTERY ’’
message on the multi-information
display, along with this indicator on,
you may need to replace the battery.
Have your vehicle's battery checked
and replaced by your dealer.

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.
