Acura RDX 2012 Owner's Manual

Low Oil Pressure Indicator
This indicator should never
come on when the engine is
running. If it starts flashing or stays
on, the oil pressure has dropped very
low or lost pressure. Serious engine
damage is possible, and you should
take immediate action.
You will also see an ‘‘OIL PRESSURE
LOW ’’message on the multi-
information display (see page 79).
The indicator notifies you of low oil
pressure and does not measure the
oil level. Check your vehicle's oil
level at each refueling.
Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn off
the engine as soon as you can safely get
the vehicle stopped. 1. Safely pull off the road, and shut
off the engine. Turn on the hazard
warning lights.
2. Let the vehicle sit for a minute. Open the hood, and check the oil
level (see page 357). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
3. If necessary, add oil to bring the level back to the full mark on the
dipstick (see page 420).
4. Start the engine, and watch the oil pressure indicator. If it does not go
out within 10 seconds, turn off the
engine. There is a mechanical
problem that needs to be repaired
before you can continue driving
(see Emergency Towing on page
475). Charging System Indicator
If the charging system
indicator comes on brightly
when the engine is running, the
battery is not being charged.
You will also see a ‘‘CHECK
CHARGING SYSTEM ’’message on
the multi-information display (see
page 79).
Immediately turn off all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.

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
(Red)U.S. CanadaThe brake system indicator (red)
normally comes on when you turn
the ignition switch to the ON (II)
position, and as a reminder to check
the parking brake. It will stay on if
you do not fully release the parking
brake.
If the brake system indicator (red)
comes on while driving, the brake
fluid level is probably low. Press
lightly on the brake pedal to see if it
feels normal. If it does, check the
brake fluid level the next time you
stop at a service station (see page
429).
You will also see a‘‘BRAKE FLUID
LOW ’’message on the multi-
information display (see page 79). If the fluid level is low, take your
vehicle to a dealer, and have the
brake system inspected for leaks or
worn brake pads.
However, if the brake pedal does not
feel normal, you should take
immediate action. A problem in one
part of the system's dual circuit
design will still give you braking at
two wheels. You will feel the brake
pedal go down much farther before
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
You will also see a
‘‘CHECK BRAKE
SYSTEM ’’message on the multi-
information display (see page 79). Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (see
Emergency
Towing on page 475).
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.

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

Checking and Replacing Fuses
If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse.
Determine from the chart on pages
473 and 474, or the diagram on the
fuse box lid, which fuse or fuses
control that device. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is
the cause. Replace any blown fuses,
and check if the device works.1. Turn the ignition switch to the LOCK (0) position. Make sure the
headlights and all other
accessories are off.
2. (Under-hood fuse boxes) Remove the cover from the fuse
box.
3. Check each of the large fuses inthe under-hood fuse box by
looking through the side window
at the wire inside. Remove the
screws with a Phillips-head
screwdriver.FUSE BLOWN

4. Check the smaller fuses in theunder-hood fuse box and all the
fuses in the interior fuse box by
pulling out each one with the fuse
puller provided on the back of the
primary under-hood fuse box
cover.
5. Look for a blown wire inside thefuse. If it is blown, replace it with
one of the spare fuses of the same
rating or lower. The spare fuses
are provided on the back of the
under-hood fuse cover. If you cannot drive the vehicle
without fixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
from one of the other circuits. Make
sure you can do without that circuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown fuse with a
spare fuse that has a lower rating, it
might blow out again. This does not
indicate that anything is wrong.
Replace the fuse with one of the
correct rating as soon as you can.

Replacing a fuse with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement fuse with the proper rating
for the circuit, install one with a lower
rating.6. If the replacement fuse of the same
rating blows in a short time, there
is probably a serious electrical
problem in your vehicle. Leave the
blown fuse in that circuit and have
your vehicle checked by a
qualified technician.
On models without navigation systemWhen the audio system is disabled,
the clock setting in the audio system
will be canceled. You will need to
reset the clock (see page 293).
On models with navigation systemIf the navigation system fuse is
removed, the navigation system will
disable itself. The next time you turn
on the ignition switch, the system
will require you to enter a PIN before
it can be used. Refer to the
navigation system manual.
