2000 Acura RL ignition

Brak
e Syste m Indicato r

The Brake System Indicator comes on when you turn the ignition ON (II). If the parking brake is not set, it
goes off after you start the engine. If
the parking brake is set, it goes off
when you fully release the parking brake with the engine running. If it comes on at any other time, it
indicates a problem with the car's
brake system. In most cases, the
problem is a low fluid level in the
brake fluid reservoir. 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 228). If the
fluid level is low, take the car to your 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. Because of the
brake system's dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will feel the brake pedal
go down much farther before the car
begins to slow down, and you will
have to press harder on the pedal.
The distance needed to stop will be much longer. Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the
longer distance needed to stop, it is
hazardous to drive the car. You should have it towed, and repaired as
soon as possible. (See Emergenc y
Towin g on page 292.)
If you must drive the car a short distance in this condition, drive
slowly and cautiously.
If the ABS indicator and the VSA system indicator come on with this
indicator, have the car inspected by
your dealer immediately.

Fuse
s

Checkin g an d Replacin g Fuse s

If something electrical in your car stops working, the first thing you
should check for is a blown fuse.
Determine from the chart on pages 290 and 291, or the diagram on the
fuse box lid, which fuse or fuses
control that component. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is
not the cause. Replace any blown
fuses and check the component's
operation.

1. Turn the ignition switch to LOCK (0). Make sure the headlights and
all other accessories are off.
2. Remove the
cover from the fuse
box.

3.
Check each

of the large fuses in
the under-hoo
d fuse box by
looking through the top at the wire
inside. Removing these fuses
requires a Phillips-head screw- driver. 4. Check the

smaller fuses in the
under-hood fuse box and all the
fuses in the interior fuse box by
pulling out each fuse with the fuse
puller provided in the door of
the
interior fuse box.

y Towin g

If you decide to tow your car with all
four wheels on the ground, make sure you use a properly-designed and
attached tow bar. Prepare the car for
towing as described above, and leave the ignition switch in Accessory (I)so the steering wheel does not lock.
Make sure the radio and any items
plugged into the accessory power socket are turned off so they do not
run down the battery.

The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in Accessory (I), and
make sure the steering wheel turns
freely before you begin towing. Trying to lift or tow your car by the

bumpers will cause serious damage.

The bumpers are not designed to

support the car's weight.

Vehicl
e Stabilit y Assis t (VSA ) Syste m

The Vehicle Stability Assist system (VSA) monitors the car's actions
during straight-line acceleration and
cornering behavior. It reduces
engine power and applies selective
braking if it senses any loss of
traction.
Controllin g Tractio n Durin g
Straight-lin e Acceleratio n
If one drive wheel is turning faster
than the other, or both drive wheels
are turning faster than the non- driven wheels, VSA senses
wheelspin. It reduces engine power and applies braking at the wheels as
necessary to increase traction.
To do this, VSA monitors the pulse frequencies from the wheel speed sensors. It also uses information
from the steering wheel angle sensor
and the lateral acceleration sensor to determine if the car is accelerating in
a straight line or if it is cornering.
VSA can then calculate how much wheelspin, if any, to allow. It signals
the ECU to reduce fuel flow andretard ignition timing. This reduces
available engine power. The ECU
will also apply braking at the wheels as necessary. When wheelspin has
been controlled, braking and engine
control return to normal.
Controllin g Tractio n Durin g
Cornerin g
VSA monitors steering input and the car's expected response to that input.
VSA's yaw rate sensor measures the car's actual cornering behavior. If VSA determines that the car is
turning more or less than expected,
the system reduces engine power
and applies braking at the
appropriate wheel to try and
maintain adequate traction during
cornering.
VSA uses the same wheel speed sensor assemblies as the ABS.
Additional sensors measure steering wheel angle, lateral acceleration, and
yaw rate.
The control unit monitors the VSA circuitry while driving. If it senses a
problem, it turns off the system and illuminates the VSA System
Indicator on the instrument panel.

Emission
s Control s

Exhaus t Emission s Control s
The exhaust emissions controls include four systems: PGM-FI,
Ignition Timing Control, ExhaustGas Recirculation and Three Way
Catalytic Converter. These four
systems work together to control the
engine's combustion and minimize
the amount of HC, CO, and NOx that comes out the tailpipe. The exhaust
emissions control systems areseparate from the crankcase and
evaporative emissions control

systems.

PGM-FI System

The PGM-FI System uses sequential multiport fuel injection.
It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Powertrain Control Module (PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how
much fuel to inject under all operat-
ing conditions. Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amountof HC, CO and NOx produced.
Exhaust Gas Recirculation (EGR)
System

The Exhaust Gas Recirculation (EGR) system takes some of the
exhaust gas and routes it back into
the intake manifold. Adding exhaust
gas to the air/fuel mixture reduces
the amount of NOx produced when
the fuel is burned.
Three Way Catalytic Converter
The three way catalytic converter is in the exhaust system. Throughchemical reactions, it converts HC,
CO, and NOx in the engine's exhaust
to carbon dioxide (CO 2), dinitrogen
(N 2), and water vapor. Replacemen
t Part s

The emissions control systems are designed and certified to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions remain low, you should use only newGenuine Acura replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the emissions from your car.
The emissions control systems are covered by warranties separate from
the rest of your car. Read your
warranty manual for more informa-
tion.
