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.

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

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.

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.
Parking38610/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu

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.

The anti-lock brake system (ABS)
helps prevent the wheels from
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the front-to-rear
braking distribution according to
vehicle loading.You should never pump the brake pedal.Let the ABS work for you by always
keeping firm, steady pressure on the
brake pedal. This is sometimes
referred to as‘‘stomp and steer. ’’You will feel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal: it is the ABS rapidly
pumping the brakes. On dry
pavement, you will need to press on
the brake pedal very hard before the
ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
ABS Indicator
If this indicator comes on, the anti-
lock function of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.
You will also see a ‘‘CHECK ABS
SYSTEM ’’message on the multi-
information display (see page 80).
If the indicator comes on while
driving, test the brakes as instructed
on page 467.
Anti-lock Brakes (ABS)38810/06/08 17:42:32 11 ACURA RDX MMC North America Owner's M 50 31STK640 enu

If the ABS indicator and the brake
system indicator come on together,
and the parking brake is fully
released, the EBD system may also
be shut down.
Test your brakes as instructed on
page 467. If the brakes feel normal,
drive slowly and have your vehicle
repaired by your dealer as soon as
possible. Avoid sudden hard braking
which could cause the rear wheels to
lock up and possibly lead to a loss of
control.Important Safety Reminders
ABS does not reduce the time or
distance it takes to stop the
vehicle.
It only helps with the
steering control during braking.
ABS will not prevent a skid that
results from changing direction
abruptly, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather
conditions.
ABS cannot prevent a loss of
stability. Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road. A vehicle with ABS may require a
longer distance to stop
on loose or
uneven surfaces, such as gravel or
snow, than a vehicle without anti-
lock.

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surfaces. It does this by
regulating the engine's output and by
selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise from the VSA
hydraulic system. You will also see
the VSA activation indicator blink.
The VSA system cannot enhance the
vehicle's driving stability in all
situations and does not control your
vehicle's entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
VSA Activation Indicator
When VSA activates, you will see the
VSA activation indicator blink (see
page 69).Vehicle Stability Assist
(VSA) System Indicator
If this indicator comes on while
driving, pull to the side of the road
when it is safe, and turn off the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
NOTE : The main function of the VSA
system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control function. If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.
You will also see a
‘‘CHECK VSA
SYSTEM ’’message on the multi-
information display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on (see page 390),
or the multi-information display
shows a ‘‘CHECK TPMS SYSTEM ’’
message with the indicator flashing
(see page 393), the VSA system
automatically turns on even if the
VSA system is turned off with the
VSA OFF switch. In this case, you
cannot turn the VSA system off by
pressing the VSA OFF switch again.
