Shift Lever Position IndicatorsThese indicators on the instrument
panel show which position the shift
lever is in.The
‘‘D ’’indicator comes on for a few
seconds when you turn the ignition
switch to the ON (II) position. If it
flashes while driving (in any shift
position), it indicates a possible
problem in the transmission.
If the malfunction indicator lamp
comes on along with the ‘‘D ’’
indicator, there is a problem with the
automatic transmission control
system. Avoid rapid acceleration, and
have the transmission checked by
your dealer as soon as possible.
When the ‘‘D ’’indicator warns of a
possible problem with the
transmission, you will see a ‘‘CHECK
TRANSMISSION ’’message on the
multi-information display (see page
80). Shifting
To shift from Park to any position,
press firmly on the brake pedal and
press the release button on the front
of the shift lever, then pull the lever.
You cannot shift out of Park when
the ignition switch is in the LOCK
(0) or the ACCESSORY (I) position.SHIFT LEVER

Park (P)
－This position
mechanically locks the transmission.
Use Park whenever you are turning
off or starting the engine. To shift out
of Park, you must press on the brake
pedal and have your foot off the
accelerator pedal. Press the release
button on the front of the shift lever
to move it.
If you have done all of the above and
still cannot move the lever out of
Park, see Shift Lock Release on
page 379.
To avoid transmission damage, come
to a complete stop before shifting
into Park. You must also press the
release button to shift into Park. The
shift lever must be in Park before
you can remove the key from the
ignition switch. Reverse (R)
－Press the brake
pedal and press the release button on
the front of the shift lever to shift
from Park to reverse. To shift from
reverse to neutral, come to a
complete stop, and then shift. Press
the release button before shifting
into reverse from neutral.
Neutral (N) －Use neutral if you
need to restart a stalled engine, or if
it is necessary to stop briefly with the
engine idling. Shift to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from neutral to
another gear.

Drive (D)－Use this position for
your normal driving. The
transmission automatically adjusts to
keep the engine at the best speed for
the driving conditions.
S Position (S) －To shift into the S
position, press the release button on
the front of the shift lever, and move
the lever to S. This position is similar
to D, except only gears from first to
fourth are selected. The S position
keeps the transmission from cycling
between fourth and fifth gears in
stop-and-go driving. With the shift lever in D or S, you
can also use the paddle shifters to
shift the transmission up or down.
Once you begin to use the paddle
shifters in S, the transmission will no
longer upshift or downshift
automatically. For more information
of driving with the paddle shifters,
see page 380.
Engine Speed Limiter
If you exceed the maximum speed
for the gear you are in, the engine
speed will enter into the
tachometer's red zone. If this occurs,
you may feel 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.Automatic Transmission37811/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu

Shift Lock Release
This allows you to move the shift
lever out of Park if the normal
method of pushing on the brake
pedal and pressing the release button
does not work.1. Set the parking brake.
2. Remove the key from the ignition switch.
3. Put a cloth on the notch of the shift lock release slot cover to prevent
scratches. Using a small flat-tip
screwdriver or a metal fingernail
file, carefully pry on the notch of
the cover to remove it.
4. Insert the key in the shift lockrelease slot.
5. Push down on the key while you press the release button on the
shift lever and move the shift lever
out of Park to neutral.
6. Remove the key from the shift lockrelease slot, then install the cover.
Make sure the notch on the cover
is on the rear.
Insert the key back into the
ignition switch, press the brake
pedal, and restart the engine.
If you need to use the shift lock
release, it means your vehicle is
developing a problem. Have it
checked by your dealer

Using the Paddle Shifters in the D
position (D-Paddle Shift Mode)
When you are driving in the D
position, pulling either paddle shifter
switches from D-normal drive mode,
to D-paddle shift mode. You can shift
the transmission up or down
manually with the paddle shifters.
Downshifting gives you more power
when climbing, and provides engine
braking when going down a steep
hill.
To shift up or down, use the＋
(right) or －(left) paddle shifter on
either side of the steering wheel.
Each time you pull ＋(right), the
transmission shifts to a higher gear.
Pull －(left) to downshift. You will
see the selected gear number on the
instrument panel.
When you pull either paddle shifter,
the gear position indicator shows you
the selected gear number.

The transmission control system
monitors the accelerator pedal use
and your driving conditions. When
you press the accelerator pedal as in
normal driving, the system judges
that you are driving at a constant
cruising speed without using the
paddle shifters. Under these
conditions, D-paddle shift mode is
canceled, and the transmission
automatically returns to drive mode
(D).
When the transmission returns to
drive mode (D), the displayed gear
number disappears.
The transmission remains in the
selected gear if you do not
accelerate.
Each time you pull either paddle
shifter, the transmission shifts one
gear up or down. If you want to shift
up or down more than two gears, pull
the paddle shifter twice, pause, and
then pull it again.The automatic transmission will not
allow you to shift up or down if:
●You downshift before the engine
speed reaches the highest
threshold of the lower gear.
If you try to do this, the gear
position indicator will flash the
number of the lower gear several
times, then return to a higher gear.●You upshift before the engine
speed reaches the lowest
threshold of the higher gear.●You pull both paddle shifters at the
same time.●You pull one of the two paddle
shifters while continuously pulling
on the other one.
The transmission downshifts to first
gear and returns to drive mode (D)
when the vehicle comes to a
complete stop or the vehicle speed is
about 6 mph (10 km/h).
If there is a problem in the
transmission while you are driving
with the paddle shifters, the D
indicator flashes, the D-paddle shift
mode is canceled, and the
transmission returns to drive mode
(D).

Using the Paddle Shifters in the S
position (Sequential Shift Mode)
With the shift lever in the S position,
you can select the sequential shift
mode to shift gears; much like a
manual transmission using the
paddle shifters, but without a clutch
pedal.
To enter the sequential shift mode,
press the release button on the front
of the shift lever, move the lever to
the S position, then pull either paddle
shifter. To cancel the sequential shift
mode and return to the ordinary
automatic transmission, move the
shift lever from the S position. When
moving the shift lever, be careful not
to operate incorrectly. While you are
driving in the sequential shift mode,
the transmission will not
automatically return to ordinary
automatic transmission.
When you move the shift lever from
‘‘D ’’to ‘‘S ’’ and pull either paddle
shifter, the gear position indicator
displays ‘‘M’’ along with the selected
gear number.
To upshift, pull the ＋(right) paddle
shifter. To downshift, pull the －
(left) paddle shifter. When you accelerate from a stop, the
transmission starts in first gear, and
you must manually upshift between
first and fifth gears. Make sure you
upshift before the engine speed
reaches the tachometer's red zone.
The transmission remains in the
selected gear (5, 4, 3, 2, or 1). There
is no automatic downshift when you
push the accelerator pedal to the
floor.
When you are driving in 4th or 5th
gear, the transmission downshifts to
the lower gear under the following
conditions:
●The vehicle slows down to a
certain speed.●You press the brake pedal.
