This indicator on the instrument
panel shows which position the shif t
lever is in.
Your Acura’s transmission has f ive
f orward speeds, and is electronically
controlled f or smoother shif ting. It
also has a ‘‘lock-up’’ torque converter
forbetterfueleconomy.Youmay
f eel what seems like another shif t
when the converter locks.
The ‘‘D ’’ indicator comes on f or a
f ew seconds when you turn the
ignition switch ON (II). If it f lashes

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

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.

transf ers varying amounts of engine
torque to the rear wheels.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 when the shif t lever is in the
1, 2 or R position. As soon as this
f eature is no longer needed, press
the VTM-4 Lock button again to

Do not use the VTM-4 Lock button on
dry, paved roads. Driving on dry,
paved roads with VTM-4 Lock ON may
damage the rear dif f erential when
making a turn. Strange noises and
vibration can also result.

torque applied to the rear tires, they
should not spin. This is normal. If
you are not able to get the vehicle to
move, apply the brakes to stop the
wheels, then reverse direction. 1.
