2002 Acura MDX engine

Apply the parking brake.
In cold weather, turn of f all
electrical accessories to reduce
the drain on the battery.
Make sure the shif t lever is in
Park. Press on the brake pedal.
Without touching the accelerator
pedal, turn the ignition key to the
START (III) position. If the engine
does not start right away, do not
hold the key in START (III) f or
more than 15 seconds at a time.
Pause f or at least 10 seconds
bef ore trying again.
If the engine does not start within
15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed half-way
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.If the engine still does not start,
press the accelerator pedal all the
way down and hold it there while
starting in order to clear f looding.
As bef ore, keep the ignition key in
the START (III) position f or no
more than 15 seconds. Return to
step 5 if the engine does not start.
If it starts, lif t your f oot of f the
accelerator pedal so the engine
does not race.
An engine is harder to start in cold
weather. The thinner air f ound at
high altitude above 8,000 f eet (2,400
meters) adds to the problem.
Use the f ollowing procedure: Turn of f all electrical accessories
to reduce the drain on the battery. Push the accelerator pedal half-
way to the f loor and hold it there
while starting the engine. Do not
hold the ignition key in START
(III) f or more than 15 seconds.
When the engine starts, release
the accelerator pedal gradually as
the engine speeds up and smooths
out.
If the engine fails to start in step 2,
push the accelerator pedal to the
f loor and hold it there while you
try to start the engine for no more
than 15 seconds. If the engine
does not start, return to step 2.

The shif t lever has eight positions. It
must be in Park or Neutral to start
the engine. When you are stopped in
D,D,D,2,1,NorR,pressfirmly
on the brake pedal, and keep your
f oot of f the accelerator pedal. YoucannotshiftoutofParkwiththe
brake pedal depressed when the
ignition switch is in LOCK (0) or
ACCESSORY (I). This position mechani-
cally locks the transmission. Use
Park whenever you are turning of f or
starting the engine. To shif t out of
Park, you must press on the brake
pedal and have your f oot of f the
accelerator pedal.
If you have done all of the above and
still cannot move the lever out of
Park, see Shif t Lock Release on page .
To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can remove the key
from the ignition switch. 215

To shif t to Reverse
f rom Park, see the explanation under
Park. To shif t to Reverse f rom
Neutral, come to a complete stop and
then shift. Use Neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to Park posi-
tion if you need to leave the vehicle
f or any reason. Press on the brake pe-
dal when you are moving the shif t
lever from Neutral to another gear.
Use this position f or
your normal driving. The
transmission automatically selects a
suitable gear for your speed and
acceleration. You may notice the
transmission shif ting up at higher
speeds when the engine is cold. This
helps the engine warm up f aster.
Your car has a reverse lockout so
you cannot accidentally shif t to
Reverse from Neutral or any other
driving position when the vehicle
speed exceeds 7 9 mph (12 14
km/h).
If you cannot shif t to Reverse when
the car is stopped, press the brake
pedal and slowly shif t to Neutral, and
then to Reverse.
If there is a problem in the reverse
lockout system, or your vehicle’s
battery is disconnected or goes dead,
you cannot shif t to Reverse. (Ref er
to Shif t Lock Release on page ).

These positions
are similar to D , except when you
select the D position, only the f irst
f our gears are selected. When you
select D , only the f irst three gears
are selected. D can also keep the
transmission f rom cycling between
f ourth and f if th gears in stop-and-go
driving, and D can keep the
transmission f rom cycling between
third and f ourth gears. This position locks
the transmission in second gear. It
does not downshif t to f irst gear
when you come to a stop. Second
gives you more power when climbing,
and increased engine braking when
going down steep hills. Use second
gear when starting out on a slippery
surf ace or in deep snow. It will help
reduce wheelspin.
ForfasteraccelerationwheninD ,
D or D , you can get the
transmission to automatically
downshif t by pushing the accelerator
pedal to the f loor. The transmission
will shif t down one or two gears,
depending on your speed.
Use D to provide engine braking
when going down a steep hill. D
gives you more power and increased
engine braking.

µIf you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
RPM below the red zone. Set the Parking brake.
With the lever in this
position, the transmission locks in
First gear.
If you shif t into First position when
the vehicle speed is above 31 mph
(50 km/h), the transmission shif ts
into Second gear f irst to avoid
sudden engine braking. This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal does not work. This procedure
is also used to release the Reverse
Lockout.
Make sure the key is in the
ignition switch LOCK (0) position.
To release the Reverse Lockout,
make sure the key is in the
ACCESSORY (I) position.

4WD System (VTM-4) automatically
transf ers varying amounts of engine
torque to the rear wheels under low
traction conditions.If more traction is needed when your
MDX is stuck or is likely to become
stuck, you can use the VTM-4 Lock
button to increase torque to the rear
wheels. As soon as this feature is no
longer needed, press the VTM-4
Lock button again to disengage the

When the brake pads need replacing,
you will hear a distinctive metallic
‘‘screeching’’ sound when you apply
the brakes. If you do not have the
brake pads replaced, they will begin
screeching all the time.
Your brakes may sometimes squeal
or squeak when you apply them
lightly. Do not conf use this with the
brakewearindicators.Theymakea
very audible ‘‘screeching.’’
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 downshif ting to a lower
gear and taking your f oot of f the
accelerator pedal.
Check your brakes af ter 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. Since a
longer distance is needed to stop
with wet brakes, be extra cautious
and alert in your driving.
Your Acura is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The ABS helps
you retain steering control when
braking very hard.
Put your f oot on the brake pedal only
when you intend to brake. Resting
your f oot on the pedal keeps the
brakes applied lightly, causing them
to build up heat. Heat build-up can
reduce how well your brakes work. It
also keeps your brake lights on all
the time, conf using drivers behind
you.
All f our brakes have audible brake
wear indicators. Brake Wear Indicators
