steering Acura RL 2004 3.5 Service Manual

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

Your Acura has been designed
primarily to carry passengers and
their cargo. You can use it to tow a
trailer if you caref ully observe the
load limits, use the proper equipment,
and f ollow the guidelines in this
section.The weight that
the tongue of a f ully-loaded trailer
puts on the hitch should be
approximately 10 percent of the
trailer weight. Too little tongue
load can make the trailer unstable
and cause it to sway. Too much
tongue load reduces f ront-tire
traction and steering control.
The total
weight of the trailer and
everything loaded in it must not
exceed 2,000 lbs (900 kg). Towing
a load that is too heavy can
seriously af f ect your car’s
handling and perf ormance. It can
also damage the engine and
drivetrain.

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
to get the trailer to move to the lef t,
andturnthewheelrighttomovethe
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 f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.
Check the f luid level in the brake
f luid reservoir monthly.
The brake f luid should be replaced
according to the time recommenda-
tion in the maintenance schedule.
Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement. However, the use of
any non-Honda brake fluid can cause
corrosion and decrease the lif e of the
system. Have the brake system
f lushed and ref illed with Honda
Heavy Duty Brake Fluid DOT 3 as
soon as possible.
Brake f luid marked DOT 5 is not
compatible with your car’s braking
system and can cause extensive
damage.
You should check the f luid level in
the power steering reservoir at least
once a year. Check the level when
the engine is cold. Look at the side
of the reservoir. The f luid should be
between the UPPER LEVEL and
LOWER LEVEL. If it is below the
LOWER LEVEL, add power steering
f luid to the UPPER LEVEL.

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.

The dust and pollen f ilter removes
pollen and dust that is brought in
f rom the outside through the climate
control system.
This f ilter 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 f rom industry and diesel-pow-
ered vehicles. Replace it more of ten
