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

™
(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.
Parking38611/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 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)38811/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 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.

Changing a Tire with TPMS
If you have a flat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated flat tire with the compact
spare tire (see page 454).
After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. After several miles
(kilometers) driving, this indicator
begins to flash, then stays on again.
You will also see a‘‘CHECK TPMS
SYSTEM ’’message on the multi-
information display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
spare tire pressure to be sure it is
correct. This indicator and the warning
message on the multi-information
display will go off, after several miles
(kilometers) driving, when the spare
tire is replaced with the specified
regular tire equipped with the tire
pressure monitor sensor.
Each wheel is equipped with a tire
pressure sensor. You must use
TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
a qualified technician.
Never use a puncture-repairing agent
in a flat tire. If used, you will have to
replace the tire pressure sensor.
Have the flat tire repaired by your
dealer as soon as possible.

Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.
VSA OFF Switch
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or fresh snow, it may be easier
to free it with the VSA temporarily
switched off. When the VSA system
is off, the traction control system is
also off. You should only attempt to
free your vehicle with the VSA off if
you are not able to free it when the
VSA is on.
Immediately after freeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
This switch is under the driver's side
vent. To turn the VSA system on and
off, press and hold it until you hear a
beep.
When VSA is off, the VSA OFF
indicator comes on as a reminder.
Press and hold the switch again. It
turns the system back on.
VSA is turned on every time you start
the engine, even if you turned it off
the last time you drove the vehicle.VSA and Tire Sizes
Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are the same size
and type as your original tires (see
page 448).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.

Driving on HillsWhen climbing hills, closely watch
your temperature gauge (see page
78). If it nears the H (Hot) mark, turn
the A/C off, reduce speed and, if
necessary, pull to the side of the road
to let the engine cool.
When driving down hills, reduce
your speed, and shift down to S
position, or use the paddle shifters to
the lower gear (3, 2 or 1)in the S
position. When towing a trailer, do
not‘‘ride ’’the brakes, and remember,
it will take longer to slow down and
stop when towing a trailer.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in place
by pressing on the accelerator, as
this can cause the automatic
transmission to overheat.
Handling Crosswinds and BuffetingCrosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
Backing UpAlways drive slowly and have
someone guide you when backing
up. Grip the
bottom
of the steering
wheel; then turn the wheel to the left
to get the trailer to move to the left,
and turn the wheel right to move the
trailer to the right.
ParkingFollow all normal precautions when
parking, including putting the
transmission in Park and firmly
setting the parking brake. Also, place
wheel chocks at each of the trailer's
tires.Towing Your VehicleYour vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page 475.

General Information
Your vehicle has been designed
primarily for use on pavement. But
its higher ground clearance and
super handling-all wheel drive
(SH-AWD) system allow you to
occasionally travel on unpaved roads,
to campgrounds, picnic sites, and
similar locations. It is not designed
for trailblazing, mountain climbing,
or other challenging off-road
activities.
If you decide to drive on unpaved
roads, you will find that it requires
somewhat different driving skills.
Your vehicle will also handle
somewhat differently than it does on
pavement. So be sure to read this
owner's manual, pay special attention
to the precautions and tips in this
section, and get acquainted with your
vehicle before you leave the
pavement.
Improperly operating this
vehicle on or off-pavement can
cause a crash or rollover in
which you and your passengers
could be seriously injured or
killed.●Follow all instructions and
guidelines in this owner's
manual.●Keep your speed low, and
don't drive faster than
conditions permit.Important Safety Precautions
To avoid loss of control or rollover,
be sure to follow all precautions and
recommendations.
●Be sure to store cargo properly,
and do not exceed your vehicle
cargo load limits (see pages 366
and 397).●Wherever you drive, make sure
you and your passengers always
wear seat belts.●Keep your speed low, and never go
faster than the conditions allow.●It's up to you to continually assess
the situation and drive within the
limits.
