The sensor on the negative terminal
monitors your vehicles battery
condition.
If there is a problem with the sensor,
you will see a‘‘CHECK BATTERY
SENSOR’’message on the
multiinformation 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 the radio fuse is removed, the
audio system will 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 digit code (see
page 308).

Maintenance
12/07/17 18:10:57 13 ACURA MDX MMC North America Owner's M 50 31STX660 enu
Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or
replaced, and put it back on your
vehicle as soon as you can.
Check the inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
60 psi (420 kPa, 4.2 kgf/cm
2)
Follow these precautions:
●Never exceed 50 mph (80 km/h).●This tire gives a harsher ride and
less traction on some road
surfaces. Use greater caution while
driving.
●Do not mount snow chains on a
compact spare.●Do not use your compact spare tire
on another vehicle unless it is the
same make and model.●After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
After several miles (kilometers)
driving with the spare, this
indicator begins to flash, then
stays on again. You will also see a
‘‘CHECK TPMS SYSTEM’’
message on the multi-information
display (see page 458).
Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed for mounting a regular tire.INDICATOR LOCATION MARK

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.
The indicator notifies you of low oil
pressure and does not measure the
oil level. Check your vehicle's oil
level at each refueling.
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 page 427). 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 517).
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
(seeEmergency Towingon page
572).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
page 87).
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.
Low Oil Pressure Indicator, Charging System Indicator56212/07/17 18:10:57 13 ACURA MDX MMC North America Owner's M 50 31STX660 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. 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 87).
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 toEmissions Testingfor more
information (see page 590).Malfunction Indicator Lamp

Taking Care of the Unexpected
12/07/17 18:10:57 13 ACURA MDX MMC North America Owner's M 50 31STX660 enu
U.S. Canada
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.
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 525).
You will also see a‘‘LOW BRAKE
FLUID’’message on the multi-
information display (see page 87).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 87).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 (seeEmergency
Towingon page 572).
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.
