check engine Acura RL 2001 3.5 Owner's Guide

Low Oil Pressure Indicator

This indicator should light when the ignition switch is ON (II), and go outafter the engine starts. It should
never come on when the engine is
running. If it starts flashing, it
indicates that the oil pressure dropped very low for a moment, then
recovered. If the indicator stays on
with the engine running, it shows that the engine has lost oil pressureand serious engine damage is
possible. In either case, you should
take immediate action.
Running the engine with low oil
pressure can cause serious mechanical damage almost immediately. Turn offthe engine as soon as you can safely get
the car stopped.

1. Safely pull off the road and shut off the engine. Turn on the hazard
warning indicators.
2. Let the car sit for a minute. Open the hood and check the oil level
(see page 171). Although oil leveland oil pressure are not directly
connected, an engine that is 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 thedipstick (see page 217 ). 4. Start the engine and watch the oil
pressure indicator. If the lightdoes not go out within ten 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 296 .)
Taking Care of the Unexpected

LOW OIL PRESSURE INDICATOR

NOTICE

Malfunction Indicator Lamp

This indicator comes on for a few
seconds when you turn the ignition
switch ON (II). If it comes on at any
other time, it indicates one of the

engine's emissions control systems

may have a problem. Even though

you may feel no difference in your
car's performance, it can reduce

your fuel economy and cause your car to put out excessive emissions.
Continued operation may cause

serious damage.
If you have recently refueled your
car, the cause of this indicator
coming on could be a loose or
missing fuel fill cap. Check the cap
and tighten it until it clicks several
times. Replace the fuel fill cap if it is missing. Tightening the cap will not
make the indicator turn off
immediately; it takes at least three driving trips.
If the indicator remains on past three
driving trips, or the fuel cap was not
loose or missing, have the car checked by the dealer as soon as
possible. Drive moderately until the dealer has inspected the problem.
Avoid full-throttle acceleration and driving at high speed.
You should also have the dealer inspect your car if this indicator
comes on repeatedly, even though it
may turn off as you continue driving.
If you keep driving with the

malfunction indicator lamp on, you can

damage your car's emissions controls

and engine. Those repairs may not be
covered by your car's warranties.
