2000 Acura RL climate control

Climat
e Contro l Syste m

Rea r Ventilatio n
The air flow from the rear vents can
be adjusted when the climate control system is on. You can adjust the direction of the
air coming from the upper vents in
the center console by moving the tab in the center of each vent up-and-down and side-to-side.
You can also adjust the amount of the air flow by sliding the air flow
control lever under the upper vents.
Slide this lever upward to increase
the amount of air flow.
(Upper position): Maximum
(Center position): Moderate (Lower position): Off

Mode Control Lever

Use the mode control lever to select
the air flow level. Air flows into the rear seat at three levels. (Upper position):
Air flows from the upper vents in the back of the center console.
— (Center position):
Air flow is divided between the upper
vents and the lower vents in the back of the center console.
(Lower position):
Air flows from the lower vents.

Senso r

The climate control system has two sensors. A sunlight sensor is located
in the top of the dashboard and a
temperature sensor is next to the steering column. Do not cover the
sensors or spill any liquid on them.

Fuel
Econom y

The condition of your car and your driving habits are the two most
important things that affect the fuel
mileage you get.
Ca r Conditio n
Always maintain your car according to the maintenance schedule. This
will keep it in top operating condition.
An important part of that mainte- nance is the Owne r Maintenanc e
Check s (see page 213 ). For
example, an underinflated tire
causes more "rolling resistance,"
which uses fuel. It also wears out
faster, so check the tire pressure at
least monthly.
In winter, the build-up of snow on
your car's underside adds weight and rolling resistance. Frequent cleaning
helps your fuel mileage and reduces
the chance of corrosion. Drivin
g Habit s
You can improve fuel economy by driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more fuel.
Always drive in the highest gear that allows the engine to run and acceler-
ate smoothly.
Depending on traffic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra fuel. Use the cruise control, when appropriate, toincrease fuel economy. A cold engine uses more fuel than a
warm engine. It is not necessary to "warm-up" a cold engine by letting it
idle for a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine will warm up faster, and you get
better fuel economy. To cut down on
the number of "cold starts," try to combine several short trips into one.
The air conditioning puts an extra load on the engine which makes ituse more fuel. Turn off the A/C orset the climate control to a higher
temperature to cut down on air
conditioning use. Use the flow-
through ventilation when the outside
air temperature is moderate.

Coolin
g Syste m

Replacin g Engin e Coolan t
The cooling system should be completely drained and refilled with
new coolant according to the time and distance recommendations in
the maintenance schedule. Only use Genuine Honda Antifreeze/Coolant.
Draining the coolant requires access
to the underside of the car. Unless
you have the tools and knowledge,
you should have this maintenance done by a skilled mechanic.

1. Turn the ignition ON (II). Turn
the heater temperature controldial to maximum heat (climate

control to 90°F/32°C). Turn off

the ignition. Open the hood. Make
sure the engine and radiator are

cool to the touch.

2. Remove the radiator cap.

3. Loosen the drain plug on the bottom of the radiator. Thecoolant will come out through the
hole in the splash cover.

Batter
y

If your car's battery is disconnected
or goes dead, the engine's computer
needs to "relearn" the idle control.
After replacing or recharging the battery:
1. Make sure the climate control sys- tem is off.
2. Start the engine and let it run until it warms up (the radiator cooling
fan comes on at least twice), and
let it idle for five more minutes.
Your audio system will also disable it-

self when the battery is disconnected

or goes dead. The next time you turn

on the radio you will see "Code" in

the frequency display. Use the Pre-
set buttons to enter the five-digit

code (see page 162 ).
Charging the battery with the cables
connected can seriously damage your
car's electronic controls. Detach the
battery cables before connecting the

battey' to a charger.

Ai
r Conditionin g Filter , Driv e Belt s

Ai r Conditionin g Filte r
The air conditioning filter removes pollen and dust that is brought in
from the outside through the climate control system.
This filter should be replaced every 30,000 miles (48,000 km) under nor-
mal conditions. It should be replaced every 15,000 miles (24,000 km) if you
drive primarily in urban areas that
have high concentrations of soot in
the air from industry and diesel-pow- ered vehicles. Replace it more often
if air flow from the climate control system becomes less than usual.
Have the air conditioning filter re-
placed by your Acura dealer. Driv
e Belt s
Check the condition of the three drive belts. Examine the edges of
each belt for cracks or fraying.
Check the tension of each belt by
pushing on it with your thumb
midway between the pulleys.
The belts should have the following

"play" or deflection.

Alternator belt:
0.37— 0.45 in (9.5 —11.5 mm)

Compressor belt:

0.31 — 0.43 in (8.0 — 11.0 mm)

Power steering belt:

0.41 — 0.49 in (10.5 —12.5 mm)

If you see signs of wear or looseness,
have your dealer adjust or replace
the belts.

Jum
p Startin g
If your car's battery has run down,
you may be able to start the engine by using a booster battery. Although
this seems like a simple procedure,
you should take several precautions.
You cannot start your Acura bypushing or pulling it. To jump start your car, follow these
directions closely:
1. Open the hood and check the physical condition of the battery
(see page 234). In very cold
weather, check the condition of
the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.

If a battery sits in extreme cold, the
electrolyte inside can freeze.
Attempting to jump start with a frozen
battery can cause it to rupture.

2. Turn off all the electrical acces- sories: climate control, stereo
system, lights, etc.
Put the transmission in Neutral or
Park and set the parking brake.

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
NOTICE

I
f You r Engin e Overheat s

The pointer of your car's tempera- ture gauge should stay in the mid-range under most conditions. It may
go higher if you are driving up a long steep hill on a very hot day. If it
climbs to the red mark, you should
determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine. Your car can overheat for several
reasons, such as lack of coolant or a

mechanical problem. The only

indication may be the temperature

gauge climbing to or above the red mark. Or you may see steam or
spray coming from under the hood.

In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn off the climate control and all
other accessories. Turn on the
hazard warning indicators.
2. If you see steam
and/or spray
coming from under the hood, turn
of

f the engine.
3. I

f you do not see steam
or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading
(climbing a long, steep hill
on a
hot day with the A/C running, for
example), the engine should start
to cool down
almost immediately.
If it does, wait
until the tempera-
ture gauge comes down
to the mid-
point then continue driving.

Do not open the hood if steam
is coming out.
