2006 Acura MDX Owner's Manual

Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
Immediately turn of f 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.
This indicator should never
come on when the engine is
running. If it starts f lashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(seeon page
). Go to a service station or garage
where you can get technical
assistance.

Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn of f
the engine as soon as you can saf ely get
the vehicle stopped.

If your vehicle battery has been
disconnected or gone dead, these
codes are erased. It takes at least
three 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 malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Ref er tofor more
inf ormation (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 f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or 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 you have recently ref ueled your
vehicle, the indicator could come on
because of a loose or missing f uel f ill
cap. Tighten the cap until it clicks at
least once. Tightening the cap will
not turn the indicator of f
immediately; it takes several days of
normal driving.

If you keep driving with the
malf unction indicator lamp on, you can
damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

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 f ully
release the parking brake.
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. Press lightly on the
brake pedal to see if it f eels normal.
If it does, check the brake f luid level
thenexttimeyoustopataservice
station (see page ).
If the f luid level is low, take the
vehicle to your dealer and have the
brake system inspected f or leaks or
worn brake pads. However, if the brake pedal does not
f eel 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 f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. 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.
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.

If your vehicle needs to be towed,
call a prof essional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.
Any other method of towing will
damage the drive system. When you
contact the towing agency, inf orm
them a f lat-bed is required.If , due to damage, your vehicle must
be towed with all f our wheels on the
ground, do the f ollowing:
With all f our wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).
The operator will load
your vehicle on the back of a truck. Release the parking brake.
Start the engine.
Shif t to D f or several seconds,
then to N.
Turn of f the engine.
The only way you can saf ely tow
your vehicle is with f lat-bed
equipment.
Emergency Towing
T aking Care of t he Unexpect ed

Towing your vehicle with two tires on
the ground will damage parts of the
4WD system. It should be transported
on a f lat-bed truck or trailer. Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shif t the transmission or start the
engine, your vehicle must be
transported with the all f our wheels of f
the ground.The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in the ACCESSORY (I)
position, and make sure the steering
wheel turns f reely bef ore you begin
towing.
Trying to lif t or tow your vehicle by the
bumpers will cause serious damage.
The bumpers are not designed to
support the vehicle’s weight.

Theinteriorfuseboxesarelocated
under the dashboard on the driver’s
and passenger’s side. The vehicle’s f uses are contained in
five fuse boxes.To open the passenger’s side f use
box, pull the right edge of the cover.
The primary under-hood f use box is
on the passenger’s side. The
secondary f use box is next to the
battery.

If something electrical in your

youshouldcheckforisablownfuse.
Determine f rom the chart on pagesand , or the diagram on the
fuse box lid, which fuse or fuses
control that device. The diagram f or
theinteriordriver’ssidefuseboxis
on the kick panel below the f use box.
Check those f uses f irst, but check all
the f uses bef ore deciding that a
blown f use is the cause. Replace any
blown f uses, and check if the device
works.
Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are of f .
Remove the cover f rom the f use
box. Check each of the large f uses in
the primary under-hood f use box
by looking through the top at the
wire inside. Removing these f uses
requires a Phillips-head
screwdriver.
Check the smaller f uses in the
under-hood f use boxes and all the
fuses in the interior fuse box by
pulling out each one with the f use
puller provided in the primary
under-hood f use box.

If you cannot drive the vehicle
without f ixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
f use with one of the correct rating as
soon as you can.
Look f or a burned wire inside the
f use. If it is burned out, replace it
withoneof thesparefusesof the
same rating or lower.
If the radio f use is removed, the
audio system will disable itself . The

will see ‘‘ ’’ in the f requency
display. Use the preset buttons to
enter the f ive-digit code (see page).
If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem with your
vehicle. Leave the blown fuse in
that circuit, and have your vehicle
checked by a qualif ied mechanic.

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.
