2011 Acura RDX engine

Your vehicle's starting system has an
auto control mode. When you turn
the ignition switch to the START (III)
position, this feature keeps the
engine's starter motor running until
the engine starts. Follow these
instructions to start the engine:1. Apply the parking brake.
2. In cold weather, turn off all electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in Park. Press on the brake pedal. 4. Without touching the accelerator
pedal, turn the ignition switch to
the START (III) position, then
release the ignition switch. You do
not need to hold the ignition
switch in the START (III) position
to start the engine. The starter
motor can run for up to 9 seconds
to guarantee starting when the
outside temperature is very low.
If you hold the ignition switch in
the START (III) position for more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs for up to 25
seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
The immobilizer system protects your
vehicle from theft. If an improperly
coded key (or other device) is used, the
engine's fuel system is disabled. For
more information, see page 124.The engine is harder to start in cold
weather. Also, the thinner air found at
altitudes above 8,000 feet (2,400
meters) adds to this problem.
Starting the Engine37410/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu

Your vehicle has an electric vacuum
pump located in the engine
compartment. When you drive in
cold weather or thinner air at high
altitude, the electric vacuum pump
operates more frequently after the
engine is started.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come from the engine
compartment. This is normal.Check Starter System Message
If there is a problem with the starter
system, you will see a
‘‘CHECK
STARTER SYSTEM ’’message on the
multi-information display when the
ignition switch is turned to the ON
(II) position. You will also see this
message when the auto control mode
of the starter system has a problem.
If this message is on, the ignition
switch has to be held in the START
(III) position manually until the
engine starts. The ignition switch can
be held in that position up to 15
seconds.
Even though you may be able to start
the engine manually without the auto
control mode of the starter system,
have your dealer inspect your
vehicle.

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 Transmission37810/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu

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 the ordinary automatic
transmission [drive mode (D)] to the
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.
