2009 Acura RL tires

Many states and Canadian provinces
require special outside mirrors when
towing a trailer. Even if they don’t,
you should install special mirrors if
you cannot clearly see behind you, or
if the trailer creates a blind spot.

agency if any other items are
recommended or required f or your
towing situation.When preparing to tow, and bef ore
driving away, be sure to check the
f ollowing:
Your vehicle tires and spare are
properly inf lated, and the trailer
tires and spare are inflated as
recommended by the trailer
maker.
The vehicle has been properly
serviced, and the suspension and
the cooling system are in good
operating condition.
The trailer has been properly

Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. 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.
Follow all normal precautions when
parking, including f irmly setting the
parking brake and putting the
transmission in Park. Also, place
wheel chocks at each of the trailer’s
tires.
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.
Always drive slowly and have
someone guide you when backing up.
Grip the of the steering
wheel; turn the wheel to the lef t to
get the trailer to move to the lef t,

trailer to the right.Your vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page .
If you must stop when f acing uphill,
use the f oot brake or parking brake.
Do not try to hold the vehicle in
placebypressingontheaccelerator,
as this can cause the automatic
transmission to overheat.
When driving down hills, reduce
your speed, and shif t down to S
position, or use the paddle shif ters to
the lower gear (3, 2 or 1) in the S
position. When towing a trailer, do
not ‘‘ride’’ the brakes, and remember,
it will take longer to slow down and
stop when towing a trailer. 519

U.S. Vehicles:
According to state and federal
regulations, f ailure to perf orm
maintenance on the items marked
with will not void your emissions
warranties. However, Acura
recommends that all maintenance
services be perf ormed in accordance
with the intervals indicated by the
multi-inf ormation display.
Youshouldcheckthefollowing
items at the specif ied intervals. If
you are unsure of how to perf orm
any check, turn to the appropriate
page listed.
We recommend using Acura parts
and fluids whenever you have
maintenance done. These are
manuf actured to the same high
quality standards as the original
components, so you can be conf ident
of their perf ormance and durability.
Your authorized dealer knows your
vehicle best and can provide
competent, ef f icient service.
However, service at a dealer is not
mandatory to keep your warranties
in effect. Maintenance may be done
by any qualif ied service f acility or
person who is skilled in this type of
automotive service. Keep all receipts
as proof of completion, and have the
person who does the work f ill out
your Maintenance Journal or
Canadian Maintenance Log. Check
your warranty booklet f or more
inf ormation. 389

Maintenance Sub Items
Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. This requires
differential fluid changes more frequently than
recommended by the Maintenance Minder. If you
regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles
(12,000 km), then every 15,000 miles (24,000 km).
Maintenance Sub Items
Rotate tires
Replace air cleaner element If you drive in dusty conditions, replace every 15,000
miles (24,000 km).
Replace dust and pollen filter If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and
from diesel-powered vehicles, replace every 15,000
miles (24,000 km).
Inspect drive belt
Replace transmission and transfer fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher
transmission and transfer temperatures.
This requires transmission and transfer fluid changes
more frequently than recommended by the
Maintenance Minder. If you regularly drive your
vehicle under these conditions, have the transmission
and transfer fluid changed at 60,000 miles
(100,000 km), then every 30,000 miles (48,000 km).
Replace spark plugs
Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), or in very low temperatures (under20°F, 29°C), replace every 60,000 mile (U.S.)/
100,000 km (Canada).
Inspect valve clearance
Replace engine coolant

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 af f ect handling and f uel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,are
more prone to damage f rom road
hazards, and wear unevenly.
Thetirepressuremonitoringsystem
(TPMS)willwarnyouwhenatire
pressure is low. See page f or
inf ormation on the TPMS.
The f ollowing pages give more
detailed inf ormation on how to take
care of your tires and what to do
when they need to be replaced.
To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.
Clean the wheels as you would the
rest of the exterior. Wash them with
thesamesolution,andrinsethem
thoroughly.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum f rom corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stif f
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a sof t brush or sponge.

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.

If you check the pressure when the
tires are hot [driven f or several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3to
0.4 kgf /cm ) higher than the cold
reading. This is normal; do not
release air to match the cold
pressure. The tires will be
underinf lated.
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.While tubeless tires have some
ability to self -seal if they are
punctured, you should look closely
f or punctures if a tire starts losing
pressure.
Even though your vehicle is
equipped with TPMS, we
recommend that you visually check
your tires every day. If you think a
tire might be low, check it
immediately with a tire gauge.
Use a gauge to measure the air
pressure in each tire 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
sparetireatthesametime.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours, or driven less than 1 mile (1.6
km).
Add or release air, if needed, to
match the recommended cold tire
pressures on page .

The following charts show the
recommended cold tire pressures f or
most normal and high-speed driving
conditions.For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb.
For additional technical inf ormation
about your tires, see page .
We strongly recommend that you do
not drive faster than the posted
speed limits and conditions allow. If
you ever drive in a sanctioned
competitive event at sustained high
speeds (over 112 mph or 181 km/h),
be sure to adjust the cold tire
pressuresasshownbelow.If youdo
not, excessive heat can build up and
cause sudden tire f ailure.Therecommendedtirepressuresfor
