2012 Acura RDX check engine

If the indicator comes on
while driving, it means one
of the engine's emissions control
systems may have a problem. Even
though you may feel no difference in
your vehicle's performance, it can
reduce your fuel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently refueled your
vehicle, the indicator coming on
could be due to a loose or missing
fuel fill cap. You will also see a
‘‘ TIGHTEN FUEL CAP ’’message on
the multi-information display.
Tighten the cap until it clicks at least
once. Tightening the cap will not turn
the indicator off immediately; it can
take several days of normal driving.
If the indicator comes on repeatedly,
even though it may turn off as you
continue driving, have your vehicle
checked by your dealer as soon as
possible.
If you keep driving with the malfunction
indicator lamp on, you can damage
your vehicle's emissions controls and
engine. Those repairs may not be
covered by your vehicle's warranties.
The indicator may also come on with
the ‘‘D ’’indicator.
You will also see a ‘‘CHECK
EMISSION SYSTEM ’’message on
the multi-information display (see
page 79).
Readiness Codes
Your vehicle has certain ‘‘readiness
codes ’’that are part of the on-board
diagnostics for the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed. If the battery in your vehicle has
been disconnected or gone dead,
these codes may be erased. It can
take several days of driving under
various conditions to set the codes
again.
To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malfunction indicator lamp will
come on for 20 seconds. If it then
goes off, the readiness codes are set.
If it blinks five times, the readiness
codes are not set. If possible, do not
take your vehicle for an emissions
test until the readiness codes are set.
Refer to
Emissions Testing for
more information (see page 490).

Brake System Indicator
(Amber)U.S. CanadaYour vehicle has an electric vacuum
pump located in the engine
compartment. It enhances the
effectiveness of your vehicle's brake
system more frequently when you
drive in cold weather or thinner air at
high altitude after the engine is
started.
When the electric vacuum pump is in
operation, it makes some mechanical
noises come from the engine
compartment. This is normal.The brake system indicator (amber)
on the instrument panel normally
comes on when you turn the ignition
switch to the ON (II) position and
goes off after the engine starts. If it
comes on at any other time, press on
the brake pedal with your foot
several times until the indicator turns
off. If the indicator is still on or
comes on again after this procedure,
there is a problem in the brake
system including the electric vacuum
pump. If this happens, the brake
pedal might feel heavy when you
press it. Have your vehicle checked
by your dealer.
You will also see a
‘‘CHECK BRAKE
SYSTEM ’’message on the multi-
information display (see page 79).Brake System Indicator46811/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu
