tire pressure Acura RL 2004 3.5 Owner's Manual

You’ll f ind many saf ety
recommendations throughout this
section, and throughout this manual.
Therecommendationsonthispage
are the ones we consider to be the
most important.Excessive speed is a major f actor in
crash injuries and deaths. Generally,
the higher the speed the greater the
risk, but serious accidents can also
occur at lower speeds. Never drive
f aster than is saf e f or current
conditions, regardless of the
maximum speed posted.
A seat belt is your best protection in
all types of collisions. Airbags
supplement seat belts, but airbags
are designed to inf late only in a
moderate to severe f rontal collision.
So even though your car is equipped
with airbags, make sure you and
your passengers always wear your
seat belts, and wear them properly.

page .) Having a tire blowout or a
mechanical f ailure can be extremely
hazardous. To reduce the possibility
of such problems, check your tire
pressures and condition f requently,
and perform all regularly scheduled
maintenance. (See page .)
Alcohol and driving don’t mix. Even
one drink can reduce your ability to
respond to changing conditions, and
your reaction time gets worse with
every additional drink. So don’t drink
and drive, and don’t let your f riends
drink and drive, either. While airbags can save lives, they
can cause serious or fatal injuries to
occupants who sit too close to them,
or are not properly restrained.
Inf ants, young children, and short
adults are at the greatest risk. Be
sure to f ollow all instructions and
warnings in this manual. (See page

If you do not f asten your seat belt,
the beeper will stop af ter a f ew
seconds but the light stays on until
you do. Both the light and the beeper
stay of f if you f asten your seat belt
bef ore turning on the ignition. This indicator lights when you turn
the ignition switch ON (II). It is a
reminder to you and your passengers
to protect yourselves by f astening
the seat belts. A beeper also sounds
if you have not fastened your seat
belt. The instrument panel has many
indicators to give you important
inf ormation about your car. This indicator comes on when you
turn the ignition switch ON (II). It
is a reminder to check the parking
brake. Driving with the parking
brake not f ully released can
damage the brakes and tires.
If the indicator remains lit after
you have f ully released the
parking brake while the engine is
running, or if it comes on while
driving, it can indicate a problem
in the brake system. For complete
inf ormation, see page .

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 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.
The air conditioning puts an extra
load on the engine which makes it
use more f uel. For better f uel
economy, either turn of f the A/C or
switch the A/C to the economy
mode. Use the flow-through
ventilation when the outside air
temperature is moderate.

this defeats the
purpose of the ABS. Let the ABS
work f or you by always keeping f irm,
steady pressure on the brake pedal
as you steer away from the hazard.
This is sometimes ref erred to as
You will f eel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal; it is the ABS rapidly
pumping the brakes.
Activation varies with the amount of
traction your tires have. On dry
pavement, you will need to press on
thebrakepedalveryhardbeforeyou
activate the ABS. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
Your car has an Anti-lock Brake
System (ABS) as standard
equipment. ABS helps to prevent the
wheels f rom locking up and skidding
during hard braking, allowing you to
retain steering control.
When the f ront tires skid, you lose
steering control; the vehicle
continues straight ahead even
though you turn the steering wheel.
The ABS helps to prevent lock-up
and helps you retain steering control
by pumping the brakes rapidly; much
f aster than a person can do it.
The ABS also balances the f ront-to
rear braking distribution according
to vehicle loading.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.

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.

Owner Maintenance Checks

µµWe recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge.
The timing belt and balancer belt
should normally be replaced at the
intervals shown in the maintenance
schedule.
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C). To saf ely operate your car, your tires
must be the proper type and size, in
good condition with adequate tread,
and correctly inf lated. The f ollowing
pages give more detailed inf ormation
on how and when to check air
pressure, how to inspect your tires
for damage and wear, and what to do
when your tires need to be replaced.
Replace these belts at 60,000 miles
(U.S.) or 100,000 km (Canada) if you
regularly drive your car in one or
more of these conditions: Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort. Underinf lated tires wear
unevenly, adversely affect handling
and f uel economy, and are more
likely to f ail f rom being overheated.
Overinf lated tires can make your car
ride more harshly, are more prone to
damage f rom road hazards, and wear
unevenly.

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this
owner’s manual regarding tire
inflation and maintenance.

Use a gauge to measure the air
pressure at least once a month. Even
tires that are in good condition may
lose one to two psi (10 to 20 kPa, 0.1
to 0.2 kgf /cm ) per month.
Remember to check the spare tire at
thesametimeyoucheckallthe
other tires.The following chart shows the
recommended cold tire pressures f or
most normal driving conditions and
speeds. Tire pressures f or high
speed driving are the same as f or
normal driving.
Thecompactsparetirepressureis:
Youshouldgetyourowntire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours. If you have to drive the
vehicle bef ore checking the tire
pressure, the tires can still be
considered ‘‘cold’’ if you drive less
than 1 mile (1.6 km). If you check the pressure when the
tires are hot [the vehicle has been
driven several miles (kilometers)],
you will see readings 4 to 6 psi (30 to
40 kPa, 0.3 to 0.4 kgf /cm ) higher
than the cold reading. This is normal.
Do not let air out to match the
specif ied cold pressure. The tire will
be underinf lated.
Add or release air, if needed, to
match the recommended cold tire
pressuresonthispage. For convenience, the recommended
tire sizes and cold air pressures are
on a label on the driver’s doorjamb.

Tubeless tires have some ability to
self -seal if they are punctured.
However, because leakage is of ten
very slow, you should look closely
for punctures if a tire starts losing
pressure.Every time you check inf lation, you
should also examine the tires f or
damage, f oreign objects, and wear.
Your car’s tires have wear indicators
molded into the tread. When the
tread wears down to that point, you
will see a 1/2 inch (12.7 mm) wide
band running across the tread. This
shows there is less than 1/16 inch
(1.6 mm) of tread lef t on the tire. A
tire that is this worn gives very little
traction on wet roads. You should
replace the tire if you can see the
tread wear indicator in three or more
places around the tire.
Excessive tread wear. Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord. Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherof theseconditions.
