2006 Acura RL Owner's Manual

You can still drive your vehicle even
if this message appears on the multi-
inf ormation display, however you
should check the temperature gauge
while driving.
If there is a problem with the
radiator system, you will see a
‘‘CHECK RADIATOR SYSTEM’’
message on the multi-inf ormation
display (see page ). If you notice the temperature gauge
climbing to or above the red mark,
Saf ely pull to the side of the road.
Follow the instructions on pages
and .
If you see this message, the engine
has probably overheated. You should
take your vehicle to a dealer, and
have it repaired as soon as possible. 78 406 407

Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(seeon page
).
This indicator should never
come on when the engine is
running. If it starts f lashing or stays
on, or if you see a ‘‘CHECK ENGINE
OIL LEVEL’’ message on the multi-
inf ormation display, the oil pressure
has dropped very low or lost
pressure. Serious engine damage is
possible, and you should take
immediate action. If the charging system
indicator comes on brightly
when the engine is running, or if you
see a ‘‘CHECK CHARGING
SYSTEM’’ message on the multi-
inf ormation display, the battery is
not being charged.
Immediately turn of f 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 dealer or a service station
where you can get technical
assistance.

Running the engine with low oil
pressure can cause serious mechanical
damage almost immediately. Turn of f
the engine as soon as you can saf ely get
the vehicle stopped.

To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Ref er tofor more
inf ormation (see page ).
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or 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 this indicator comes on
while driving, or if you see
a ‘‘CHECK EMISSION
SYSTEM’’ message in the multi-
inf ormation display, it means one of
the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. If the indicator comes on repeatedly,
even though it may go of f as you
continue driving, have the vehicle
checked by your dealer as soon as
possible.
If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. You will also see a
‘‘TIGHTEN FUEL CAP’’ message on
the multi-information display.
Tighten the cap until it clicks at least
once (see page ). Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving. 298

If you keep driving with the
malf unction indicator lamp on, you can
damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties.

However, if the brake pedal does not
f eel 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 f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down, and
you will have to press harder on the
pedal.Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. 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
on page ).
If the f luid level is low, take your
vehicle to a dealer, and have the
brake system inspected f or leaks or
worn brake pads.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display.
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. You will see a
‘‘BRAKE FLUID LOW’’ message on
the multi-information display. Press
lightly on the brake pedal to see if it
f eels normal. If it does, check the
brake f luid level the next time you
stop at a service station (see page
). The brake system
indicator normally
comes on when
you turn the ignition switch to the
ON (II) position and as a reminder to
check the parking brake. If you do
not release the parking brake, the
indicator will stay on, and you will
see a ‘‘RELEASE PARKING
BRAKE’’ message on the multi-
inf ormation display.
