2007 Acura MDX check engine light

This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, the pointer
may rise to the upper zone. If it
reaches the red (hot) mark, pull
safely to the side of the road. For instru
ctions and precautions on
checking the engine’s cooling
system, see page . This shows how much f uel you
have. It may show slightly more
or less than the actual amount.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator in the instrument
panel to come on. If this happens,
you will see which tire is losing
pressure on the multi-inf ormation
display along with a ‘‘CHECK TIRE
PRESSURE’’ message.When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. You
should stop and check your tires as
soon as possible, and inf late them to
the proper pressure as indicated on
the vehicle’s tire inf ormation placard.
It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure
indicator and message on the multi-
inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexpectedly. Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability. If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire.

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. Emergency
Brake Assist System increases the
stopping f orce when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your f oot on the brake pedal
applies the brakes slightly. This
builds up heat, and reduces brake
ef f ectiveness and brake pad lif e. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
All f our brakes have audible brake
wear indicators.
If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.

Under these conditions, trailer
stability assist begins to stabilize the
vehicl e/trailer combination by
reducing the vehicle speed. The
control unit sends signals to
selectively apply the brakes and
regulate the engine output. The
brake lights of your vehicle will be
turned on automatically by the
system even if you do not keep the
pressu re on the brake pedal.
Your
vehicle is equipped with trailer
stability assist function. This
function works on the same sensors
as the vehicle stability assist (VSA)
system. This function helps to
stabilize the vehicl e/trailer
combination when the trailer
severely sways or oscillates. For
more information of the VSA system,
see page .
When the brakes are applied, the
trailer’s brake lights come on along
wi th the vehicle brake lights.
When the trailer stability assist
activates, you will see the VSA
activation indicator blink. There may
also be some noise from the VSA
hydraulic system. Trailer
stability assist cannot prevent
a loss of control. Always reduce the
ve hicle speed and steer firmly. Do
not brake suddenly or make quick
steering motion. It could cause the
trailertojackknifeorturnoverand
the system becomes ineffective.
Trailer stability assist cannot prevent
swaying that can occur in crosswinds
and in normal and emergency
driving maneuvers. It helps only to
stabilize the vehicl e/trailer
combination in these conditions,
after the oscillation becomes severe.
If
the function detects the vehicle/
trailer instability, it checks if the
swaying is caused by the trailer, and
if the trailer swaying or oscillation is
increasing.
The vehicle/trailer combination is
more affected by crosswinds,
buffeting, and improper tongue load.
These conditions can make the
trailer unstable, and cause it to sway. Always obey the recommended
speed limits f or towing a trailer, see
page . Trailer stability assist will also be
inef f ective while driving at high
speed or towing a trailer with a high
center or gravity.

IfyouturnofftheVSA,thetrailer
stability assist function also shuts off.
Press and hold the VSA off switch
until you hear a beep (see page ).
The VSA activation indicator comes
on as a reminder. Press and hold the
switch again to turn the system on.
The function turns on every time you
start the engine along with the VSA,
even if you turned it off the last time
you drove the vehicle.
The control unit monitors the VSA
circuitry and the braking system. If
there is a problem with the brake
lighting system, the trailer stability
assist function shuts down and the
‘‘CHECK TRAILER STABILITY
ASSIST’’ message appears on the
multi-info rmation display.
If you see this message, have your
vehicle checked at your dealer as
soon as possible. In
this case, your vehicle still has the
VSA traction and stability
enhancem ent, but it will not have the
trailer stability assist function.

Diagnosing why the engine won’t
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position: You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run.
Wh en you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all. Check
the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
on page . 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 connec-
tions (see page ). You can
then try jump starting the vehicle
from a booster battery (see page
).
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, 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 dash panel to blink
rapidly(seepage ).
Check these things: Turn
the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
areOK,thereisprobably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
on page . 426
