µExercise extra caution when driving
in rain af ter a long dry spell. Af ter
months of dry weather, the f irst
rains bring oil to the surf ace of the
roadway, making it slippery.
Rain, f og, and snow conditions
require a dif f erent driving technique
because of reduced traction and
visibility. Keep your car well-
maintained and exercise greater
caution when you need to drive in
bad weather. The cruise control
should not be used in these
conditions. Always drive
slower than you would in dry
weather. It takes your car longer to
react, even in conditions that may
seem just barely damp. Apply
smooth, even pressure to all the
controls. Abrupt steering wheel
movements or sudden, hard appli-
cation of the brakes can cause loss of
control in wet weather. Be extra
cautious f or the f irst f ew miles
(kilometers) of driving while you
adjust to the change in driving
conditions. This is especially true in
snow. A person can f orget some
snow-driving techniques during the
summer months. Practice is needed
to relearn those skills. Driving T echnique

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.
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 ).
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.

Follow all normal precautions when
parking, including putting the
transmission in Park and f irmly
setting the parking brake. Also, place
wheel chocks at each of the trailer’s
tires.
Always drive slowly and have
someone guide you when backing up.
Grip the of the steering
wheel; then turn the wheel to the lef t

trailer to the right. Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause trailer
swaying. When being passed by a
large vehicle, keep a constant speed
and steer straight ahead. Do not try
to make quick steering or braking
corrections.

The air cleaner element should be
cleaned or replaced according to the
time and distance recommendations
in the maintenance schedule.
Clean the air cleaner element by
blowing compressed air through it in
the opposite direction to normal air
f low. If you do not have access to
compressed air (such as a service
station), ask your Acura dealer to do
this service.
Follow the replacement procedure
for removal and reinstallation.
Always use Honda Power Steering
Fluid. If it is not available, you may
use another power steering f luid as
an emergency replacement.
However, continued use can cause
increased wear and poor steering in
cold weather. Have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently, and have
the system inspected as soon as
possible.
Clean the hood latch assembly with a
mild cleaner, then lubricate it with a
multipurpose grease. Lubricate all
the moving parts (as shown),
including the pivot. Follow the time
and distance recommendations in
the Maintenance Schedule. If you
are not sure how to clean and grease
the latch, contact your Acura dealer.

T urning the steering wheel to f ull lef t
or right lock and holding it there can
damage the power steering pump.

In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
The tires were properly balanced by
the factory. They may need to be
rebalanced at some time bef ore they
are worn out. Have your dealer
check the tires if you f eel a consis-
tent vibration while driving. A tire
should always be rebalanced if it is
removed f rom the wheel f or repair.To help increase tire lif e and
distribute wear more evenly, you
should have the tires rotated every
7,500 miles (12,000 km). Move the
tires to the positions shown in the
chart each time they are rotated.
Make sure the installer balances the
wheels when you have new tires
installed. This increases riding
comf ort and tire lif e. Your car’s
original tires were dynamic or ‘‘spin’’
balanced at the f actory. For best
results, have the installer perf orm a
dynamic balance.

Improper wheel weights can damage
your car’s aluminum wheels. Use only
genuine Acura wheel weights f or
balancing.

When shopping f or replacement
tires, you may find that some tires
are ‘‘directional.’’ This means they
are designed to rotate only in one
direction. If you use directional tires,
they should be rotated only front-to-
back.It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, then replace the two
f ront tires or the two rear tires as a
pair. Replacing just one tire can
seriously af f ect your car’s handling.
The tires that came with your car
were selected to match the perform-
ance capabilities of the vehicle while
providing the best combination of
handling, ride comf ort, and long lif e.
Youshouldreplacethemwithradial
tires of the same size, load range,
speed rating, and maximum cold tire
pressure rating (as shown on the
tire’s sidewall). Mixing radial and
bias-ply tires on your car can reduce
its braking ability, traction, and
steering accuracy.

Installing improper tires on your
car can affect handling and
stability. This can cause a crash
in which you can be seriously
hurt or killed.
Always use the size and type of
tires recommended in this
owner’s manual.

´
Tires that are marked ‘‘M S’’ or
‘‘All Season’’ on the sidewall have an
all-weather tread design. They
should be suitable f or most winter
driving conditions. Tires without
these markings are designed f or
optimum traction in dry conditions.
They may not provide adequate
perf ormance in winter driving.
For the best perf ormance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.

See page f or inf ormation about
DOT Tire Quality Grading.
The ABS and VSA system work by
comparing the speed of the wheels.
When replacing tires, use the same
size originally supplied with the
vehicle. Tire size and construction
can af f ect wheel speed and may
cause the system to work
inconsistently.
If you ever need to replace a wheel,
make sure you use an identical style
aluminum alloy wheel that originally
came on your Acura. Replacement
wheels are available at your Acura
dealer. 340

f or maximum speed recommen-
dations.Because your Acura has limited tire
clearance, mount only SAE Class ‘‘S’’
cable-type traction devices on the
front tires. Use traction devices only
when required by driving conditions
or local laws. Make sure they are the
correct size f or your tires.
Metal link-type ‘‘chains’’ should not
be used. No matter how tight they
seem to be installed, they can come
into contact with the body and
suspension, causing serious damage.When installing cables, f ollow the
manufacturer’s instructions and
mount them as tightly as you can.
Drive slowly with them installed. If
youhearthemcomingincontact
with the body or chassis, stop and
investigate. Make sure the cables are
installed tightly, and that they are
not contacting the brake lines or
suspension. Remove them as soon as
you begin driving on cleared roads.
