2009 Acura RDX ECO mode

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist using negative pressure
generated by the engine and the
electric vacuum pump helps reduce
the ef f ort needed on the brake pedal.
The anti-lock brake system (ABS)
helps you retain steering control
when braking very hard.All f our brakes have audible brake
wear indicators.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
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 f or
the brakes to occasionally squeal or
squeak when you apply them.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.
When you drive in cold weather or
thinner air at high altitude, the
electric vacuum pump operates more
f requently af ter the engine is started.
For more inf ormation about the
electric vacuum pump, see page . Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Check your brakes af ter driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious and alert in your driving.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come f rom the engine
compartment. This is normal.

To see the inf lation pressures of all
f our tires, press the SEL/RESET
button. The display changes as
shown above.
Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message.When any of the tires have low
pressure, the tire pressure monitor
shows a ‘‘TIRE PRESS. ERROR
SYSTEM FUNC NORMAL’’
message.
When you continue driving af ter
installing the spare tire, you will also
see this message on the multi-
inf ormation display.

We recommend using Acura parts
and fluids whenever you have
maintenance done. These are
manuf actured to the same high-
quality standards as the original
components, so you can be conf ident

Your authorized Acura dealer knows
your vehicle best and can provide
competent, ef f icient service.
However, service at a dealer is not
mandatory to keep your warranties
in effect. Maintenance may be done
by any qualif ied service f acility or
person who is skilled in this type of
automotive service. Keep all receipts
as proof of completion, and have the
person who does the work f ill out
your Maintenance Journal or
Canadian Maintenance Log. Check
