2009 Acura MDX battery

●Are you using the proper starting
procedure? Refer toStarting the
Engine on page339.●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
page440).
If you find nothing wrong, you will
need a qualified technician to find the
problem. See Emergency Towing on
page446. Jump Starting
Although this seems like a simple
procedure, you should take several
precautions.
A battery can explode if you do
not follow the correct
procedure, seriously injuring
anyone nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
You cannot start your vehicle by
pushing or pulling it.
To Jump Start Your Vehicle:1. Open the hood, and check the physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or frozen, do not try
jump starting until it thaws.If a battery sits in extreme cold, the
electrolyte inside can freeze. Attempting
to jump start with a frozen battery can
cause it to rupture.
2. Turn off all the electricalaccessories: heater, A/C, climate
control, audio system, lights, etc.
Put the transmission in neutral or
Park, and set the parking brake.

The numbers in the illustration show
you the order to connect the jumper
cables.3. Connect one jumper cable to the positive (＋ ) terminal on your
vehicle's battery. Connect the
other end to the positive (＋ )
terminal on the booster battery.
4. Connect the second jumper cable to the negative (－ ) terminal on
the booster battery. Connect the
other end to the grounding strap
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.

Low Oil Pressure Indicator
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 indicators.
2. Let the vehicle sit for a minute. Open the hood, and check the oil
level (see page326).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 page393).
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
446). Charging System Indicator
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
page81).
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 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. 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
page81). Readiness Code
Your 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, 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 page463).

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.
