Cruise control allows you to maintain
a set speed above 25 mph (40 km/h)
without keeping your foot on the
accelerator pedal. It should be used
for cruising on straight, open
highways. It is not recommended for

Break-in Period
Help assure your vehicle's future
reliability and performance by paying
extra attention to how you drive
during the first 600 miles (1,000 km).
During this period:●Avoid full-throttle starts and rapid
acceleration.●Avoid hard braking for the first 200
miles (300 km).●Do not change the oil until the
scheduled maintenance time.●Do not tow a trailer.
You should also follow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced. Fuel Recommendation
Your vehicle is designed to operate
on premium unleaded gasoline with
a pump octane of 91 or higher. If this
octane grade is unavailable, regular
unleaded gasoline with a pump
octane of 87 or higher may be used
temporarily. The use of regular
unleaded gasoline can cause metallic
knocking noises in the engine and
will result in decreased engine
performance. The long-term use of
regular-grade gasoline can lead to
engine damage.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the catalytic converter.
To help prevent harmful fuel system and
engine deposits, use high quality fuel
containing detergent and additives. In
addition, in order to maintain good
performance, fuel economy, and
emissions control, we strongly
recommend the use of gasoline that
does NOT contain harmful manganese-
based fuel additives such as MMT, if
such gasoline is available.

Improper accessories or
modifications can affect your
vehicle's handling, stability, and
performance, and cause a
crash in which you can be hurt
or killed.
Follow all instructions in this
owner's manual regarding
accessories and modifications.
When properly installed, cellular
phones, alarms, two-way radios, and
low-powered audio systems should
not interfere with your vehicle's
computer controlled systems, such
as your airbags, anti-lock brakes, and
tire pressure monitoring system. Before installing any accessory:
●Make sure the accessory does not
obscure any lights, or interfere
with proper vehicle operation or
performance.●Be sure electronic accessories do
not overload electrical circuits (see
page 469) or interfere with proper
operation of your vehicle.●Before installing any electronic
accessory, have the installer
contact your dealer for assistance.
If possible, have your dealer
inspect the final installation.●Do not install accessories on the
side pillars or across the rear
windows. Accessories installed in
these areas may interfere with
proper operation of the side
curtain airbags.Modifying Your Vehicle
Removing parts from your vehicle, or
replacing components with non-
Acura components could seriously
affect your vehicle's handling,
stability, and reliability.
Here are some examples:
●Lowering the vehicle with a non-
Acura suspension kit that
significantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.●Raising your vehicle with a non-
Acura suspension kit can affect the
handling, stability, and reliability.

●Non-Acura wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).●Larger or smaller wheels and tires
can interfere with the operation of
your vehicle's anti-lock brakes and
other systems.●Modifying your steering wheel or
any other part of your vehicle's
safety features can make the
systems ineffective.
If you plan to modify your vehicle,
consult your dealer.Accessories and Modifications36411/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu

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.
