2001 Acura RL air conditioning

Climate Control System

Semi-automatic Operation
You can manually select various functions of the Climate Controlsystem when it is in FULL AUTO.
All other features remain auto- matically controlled. Making any
manual selection causes the wordFULL to go out.

Air Conditioning (A/C) Button
Press the A/C button to operate the
air conditioning. Each time you press
the A/C button, the display shows
the mode: A/C ECON, A/C OFF, or

A/C ON.
When you turn the A/C off, the sys-
tem cannot regulate the inside tem-
perature if you set the dial below theoutside temperature. With the A/C
on, use the temperature control dial
to adjust the temperature of the air
flow to a comfortable setting. With the A/C in economy mode, you
will see A/C ECON in the system's
display. Use this mode to get better
fuel economy.
In this mode, you may feel a slight re-

duction in cooling efficiency. If you

want more cooling, select A/C ON or
FULL AUTO.

Fuel Economy

The condition of your car and your driving habits are the two most
important things that affect the fuel
mileage you get.
Car Condition
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 Owner Maintenance
Checks (see page 215 ). 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. Driving Habits
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, to
increase 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 it
use 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.

Before Driving

Driving in Bad Weather

Visibility — Being able to see clearly in all directions and being
visible to other drivers are important in all weather conditions. This is
more difficult in bad weather. To be seen more clearly during daylight
hours, turn on your headlights.
Inspect your windshield wipers and
washers frequently. Keep the wind- shield washer reservoir full of the
proper fluid. Have the windshield
wiper blades replaced if they start to streak the windshield or leave parts
unwiped. Use the defroster and air conditioning to keep the windows
from fogging up on the inside (see
pages 128 and 133). Traction — Check your tires
frequently for wear and properpressure. Both are important in
preventing "hydroplaning" (loss of
traction on a wet surface). In the
winter, mount snow tires on all four
wheels for the best handling.
Watch road conditions carefully, they can change from moment tomoment. Wet leaves can be as slip-
pery as ice. "Clear" roads can have
patches of ice. Driving conditionscan be very hazardous when the
outside temperature is near freezing.
The road surface can become covered with areas of water puddles
mixed with areas of ice, so your
traction can change without warning.
Be careful when downshifting. If
traction is low, you can lock up the drive wheels for a moment and cause
a skid. Be very cautious when passing, or
being passed by other vehicles. The spray from large vehicles reduces
your visibility, and the wind buffeting can cause you to lose control.
Driving

Towing a Trailer

Driving Safely With a Trailer
The added weight, length, and height of a trailer will affect your
vehicle's handling and performance, so driving with a trailer requires
some special driving skills and
techniques.
For your safety and the safety ofothers, take time to practice driving
maneuvers before heading for the open road, and follow the guidelines
discussed below.

Towing Speeds and Gears

Drive slower than normal in all
driving situations, and obey posted
speed limits for vehicles with trailers.
Use the D4 position when towing a
trailer on level roads. D3 is the
proper shift lever position to use
when towing a trailer in hilly terrain. (See "Driving on Hills" in the next
column for additional gear information.) Making Turns and Braking
Make turns more slowly and wider
than normal. The trailer tracks a smaller arc than your vehicle, and it
can hit or run over something the
vehicle misses. Allow more time and distance for braking. Do not brake or
turn suddenly as this could cause the trailer to jackknife or turn over.

Driving on Hills

When climbing hills, closely watch your temperature gauge. If it nearsthe red (Hot) mark, turn the air conditioning off, reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shifts
frequently between 3rd and 4th
gears while going up a hill, shift to
D3.
If you must stop when facing uphill,
use the foot brake or parking brake. Do not try to hold the vehicle in
place by pressing on the accelerator, as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed and shift down to 2nd gear. Do not "ride" the brakes, andremember it will take longer to slowdown and stop when towing a trailer.

Maintenance

This section explains why it is important to keep your car well
maintained and to follow basic
maintenance safety precautions.
This section also includes Maintenance Schedules for normal
driving and severe driving conditions,
a Maintenance Record, and instruc-
tions for simple maintenance tasks
you may want to take care of
yourself.
If you have the skills and tools to per-
form more complex maintenance
tasks on your Acura, you may want
to purchase the Service Manual. See
page 319 for information on how to obtain a copy, or see your Acura

dealer.
