2007 Acura MDX Owner's Manual

If the temperatu re gauge stays at
the red mark, turn off the engine.
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
on page ). Start
the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). 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.
Put the radiator cap back on
tightl y. Run the engine, and check
the temperatu re gauge. If it goes
back to the red mark, the engine
needs repair (see on page ).
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.
If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
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 tempera-
ture gauge, or lower, bef ore check-
ing the radiator.
Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.

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.

Safely pull off the road, and shut
off the engine. Turn on the hazard
warning indicators.
Let the vehicle sit for a minute.
Op en 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
dipsti ck (see page ). If
the charging system
indicator comes on brightly
wh en the engine is running, the
battery is not being charged.
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.
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 m echanical
problem that needs to be repaired
befo re you can continue driving
(see on page
). You
will also see a ‘‘CHECK
CHARGI NG SYSTEM’’ message on
the multi-information display (see
page ).
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.
Go to a service station or garage
where you can get technical
assistance.
You will also see a ‘‘CHECK

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 a state
emissions test until the readiness
codes are set. Refer to
for more
info rmation (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 feel no difference in
your vehicle’s performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damag e.If
the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
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 norm al driving.
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.
You
will also see a ‘‘CHECK
EMISSION SYSTEM’’ message on
the multi-information display (see
page ). If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.

The brake system indicator
norm ally 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
thenexttimeyoustopataservice
station (see page ). 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.
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 indicato r, have your
vehicle inspected by your dealer
immediately.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inform ation display (see page ).
If
the fluid level is low, take the
vehicle to your 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 ‘‘LOW BRAKE
FLUI D’’ message on the multi-
info rmation display (see page ).
