You can manually select various
f unctions of the Climate Control
system when it is in FULL AUTO.
All other f eatures remain auto-
matically controlled. Making any
manual selection causes the word
FULL to go out.
Press the A/C button to turn the air
conditioningonandoff.Youwillsee
A/C ON or A/C OFF in the display.
When you turn the A/C of f , the sys-
tem cannot regulate the inside tem-
perature if you set the dial below the
outside temperature. With the A/C
on, use the temperature control dial
to adjust the temperature of the air
flow to a comfortable setting.This button controls the source of
the air going into the system. When
the indicator in this button is lit, air
from the car’s interior is sent
through the system again
(Recirculation mode). When the
indicator is of f , air is brought in f rom
outside the car (Fresh Air mode).You can, f or example, manually put
the system in recirculation mode
when driving through an area of
smoke or f umes.

A cold engine uses more f uel than a
warm engine. It is not necessary to
‘‘warm-up’’ a cold engine by letting it
idle f or a long time. You can drive
away in about a minute, no matter
how cold it is outside. The engine
will warm up f aster, and you get
better f uel economy. To cut down on
the number of ‘‘cold starts,’’ try to
combine several short trips into one.
You can improve f uel economy by
driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more f uel.
Always drive in the highest gear that
allows the engine to run and acceler-
ate smoothly.
An important part of that mainte-
nance is the (see page ). For
example, an underinf lated tire
causes more ‘‘rolling resistance,’’
which uses f uel. It also wears out
f aster, so check the tire pressure at
least monthly. The air conditioning puts an extra
load on the engine which makes it
usemorefuel.Turnoff theA/Cor
set the climate control to a higher
temperature to cut down on air
conditioning use. Use the f low-
through ventilation when the outside
air temperature is moderate.
The condition of your car and your
driving habits are the two most
important things that affect the fuel
mileage you get.
Always maintain your car according
to the maintenance schedule. This
will keep it in top operating condition.
In winter, the build-up of snow on
your car’s underside adds weight and
rolling resistance. Frequent cleaning
helps your f uel mileage and reduces
thechanceof corrosion.
Depending on traf f ic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra f uel. Use the
cruise control, when appropriate, to
increase f uel economy.

µµBeing able to see
clearly in all directions and being
visible to other drivers are important
in all weather conditions. This is
more dif f icult in bad weather. To be
seen more clearly during daylight
hours, turn on your headlights. Check your tires
f requently f or wear and proper
pressure. Both are important in
preventing ‘‘hydroplaning’’ (loss of
traction on a wet surface). In the
winter, mount snow tires on all f our
wheels f or the best handling.
Watch road conditions caref ully,
they can change f rom moment to
moment. Wet leaves can be as slip-
pery as ice. ‘‘Clear’’ roads can have
patches of ice. Driving conditions
can be very hazardous when the
outside temperature is near f reezing.
The road surf ace can become
covered with areas of water puddles
mixed with areas of ice, so your
traction can change without warning.
Be caref ul when downshif ting. If
traction is low, you can lock up the
drive wheels f or a moment and cause
askid. Be very cautious when passing, or
beingpassedbyothervehicles.The
spray f rom large vehicles reduces
your visibility, and the wind buf f eting
can cause you to lose control.
Inspect your windshield wipers and
washers f requently. Keep the wind-
shield washer reservoir f ull of the
proper f luid. Have the windshield
wiper blades replaced if they start to
streak the windshield or leave parts
unwiped. Use the def roster and air
conditioning to keep the windows
f rom f ogging up on the inside (see
pages and ).

The added weight, length, and
height of a trailer will af f ect your
vehicle’s handling and perf ormance,
so driving with a trailer requires
some special driving skills and
techniques.

smaller arc than your vehicle, and it

vehicle misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.

When towing a trailer in the

depending on the vehicle speed and
road condition. Do not use Fif th gear.
The recommended speed range f or
each gear position is shown in the
table.
Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
If you have an automatic
transmission, use the D or D
position when towing a trailer on
level roads. D is the proper shif t
lever position to use when towing a
trailer in hilly terrain. (See ‘‘ ’’ in the f ollowing column f or
additional gear information.) If the automatic transmission shif ts
f requently between 4th and 5th
gears while going up a hill, shif t to
D . And if the transmission shif ts

gears, shif t to D .

If you have the skills and tools to per-
f orm more complex maintenance
tasks on your Acura, you may want
to purchase the Service Manual. See

obtain a copy, or see your Acura
dealer. This section also includes
Maintenance Schedules f or normal
driving and severe driving conditions,
a Maintenance Record, and instruc-
tions f or simple maintenance tasks
you may want to take care of
yourself . This section explains why it is

Remove the blade f rom its holder
by grasping the tabbed end of the
blade. Pull f irmly until the tabs
come out of the holder.Examine the new wiper blades. If
they have no plastic or metal rein-
f orcement along the back edge,
remove the metal reinf orcement
strips f rom the old wiper blade and
install them in the slots along the
edge of the new blade.Slide the new wiper blade into the
holder until the tabs lock.
Slide the wiper blade assembly
onto the wiper arm. Make sure it
locks in place.

Run the air conditioning at least once
a week during the cold weather
months. Run it f or at least ten
minutes while you are driving at a
steady speed with the engine at
normal operating temperature. This
circulates the lubricating oil con-
tained in the ref rigerant.If the air conditioning does not get as
cold as before, have your dealer
check the system. Recharge the
system with Ref rigerant HFC-134a
(R-134a). (See Specif ications on page
.)
Periodically check the engine’s
radiator and air conditioning
condenser f or leaves, insects, and
dirt stuck to the f ront surf ace. These
block the air f low and reduce cooling
ef f iciency. Use a light spray f rom a
hose or a sof t brush to remove them. Your car’s air conditioning is a sealed
system. Any major maintenance,
such as recharging, should be done
by a qualif ied mechanic. You can do
a couple of things to make sure the
air conditioning works ef f iciently. 326

Whenever you have the air conditioning
system serviced, make sure the service
f acility uses a ref rigerant recycling
system. This system captures the
ref rigerant f or reuse. Releasing
ref rigerant into the atmosphere can
damage the environment.
The condenser and radiator f ins bend
easily. Only use a low-pressure spray
or sof t-bristle brush to clean them.
