2011 Acura RDX Owner's Manual

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.

Downshifting with the paddle shifter
allows you to increase the engine
braking when going down steep or
long hills, and provides more power
when climbing uphills. You can
upshift the transmission manually to
reduce the rpm.
The transmission also shifts
automatically as the vehicle comes to
a complete stop. It downshifts to first
gear when the vehicle speed reaches
6 mph (10 km/h) or less.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 try to shift to third or a higher
gear when the vehicle is
stationary.●You pull both paddle shifters at the
same time.●You pull one of the two paddle
shifters while continuously pulling
on the other one.
Starting in Second GearWhen you are in sequential shift
mode, and the vehicle is stopped,
pull the
＋(right) paddle shifter to
shift to second gear. You will see
‘‘ M2’’ in the display. Starting in
second gear helps to reduce
wheelspin in deep snow or on a
slippery surface.

Recommended Shift PointsDrive in the highest gear that lets the
engine run and accelerate smoothly.
This will give you good fuel economy
and effective emissions control. The
following shift points are
recommended:Shift up Normal acceleration
1st to 2nd
2nd to 3rd 3rd to 4th4th to 5th 15 mph (24 km/h)
25mph (40 km/h)
40 mph (64 km/h)
47 mph (76 km/h) Super Handling-All Wheel Drive
™
(SH-AWD
®) System
If equippedThe super handling-all wheel drive
(SH-AWD) system is a full time all-
wheel-drive system that
automatically controls and transfers
varying amounts of engine torque to
all wheels independently, according
to the driving conditions.
While the SH-AWD system helps to
enhance the vehicle's driving
stability in all situations, it is still
your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety. SH-AWD Torque Distribution
Monitor
The SH-AWD torque distribution
monitor on the multi-information
display shows you the amount of
torque being sent to the wheels.
Each wheel
－right front (RF), left
front (LF), right rear (RR), and left
rear (LR) －has its own torque
indicator.

Each torque indicator is displayed as
a bar graph divided into 5 segments.
The number of segments represents
the amount of torque distributed to
each wheel.
When there is only a slight change in
torque distribution while driving,
such as cruising on level roads at the
same speed, the torque distribution
monitor may stop displaying the
amount of torque. This is not a
system problem. The monitor will
show the amount if the system
senses any change in torque
distribution.
If the SH-AWD indicator blinks while
driving, it indicates the differential
temperature is too high. You will also
see an‘‘SH-AWD DIFF TEMP
HIGH ’’message on the multi-
information display. If this happens,
pull to the side of the road when it is
safe, shift to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.
If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘ CHECK SH-AWD SYSTEM ’’
message also appears on the multi-
information display, there is a
problem with the SH-AWD system.
Your vehicle still has normal front-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible.

Always use the parking brake when
you park your vehicle. Make sure the
parking brake is set firmly, or your
vehicle may roll if it is parked on an
incline.
Set the parking brake before you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.Parking Tips
●Make sure the moonroof and the
windows are closed.●Turn off the lights.●Place any packages, valuables, etc.
in the cargo area or take them with
you.●Lock the doors and the tailgate.●Never park over dry leaves, tall
grass, or other flammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
●If the vehicle is facing uphill, turn
the front wheels away from the
curb.●If the vehicle is facing downhill,
turn the front wheels toward the
curb.●Check the indicator on the
instrument panel to verify that the
security system is set.●Make sure the parking brake is
fully released before driving away.
Driving with the parking brake
partially set can overheat or
damage the rear brakes.

Your vehicle is equipped with disc
brakes at all four wheels. A power
assist using negative pressure
generated by the engine and the
electric vacuum pump helps reduce
the effort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come from the engine
compartment. This is normal.
When you drive in cold weather or
thinner air at high altitude, the
electric vacuum pump operates more
frequently after the engine is started.
For more information about the
electric vacuum pump, see page 468.Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check your brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious and alert in your driving.Braking System Design
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Brake Pad Wear Indicators
All four 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 for
the brakes to occasionally squeal or
squeak when you apply them.
