3. Examine the new wiper blades. Ifthey have no plastic or metal
reinforcement along the back
edge, remove the metal
reinforcement strips from the old
wiper blade, and install them in the
slots along the edge of the new
blade.
4. Slide the new blade into the wiperarm. Make sure it is engaged in
the slot along its full length.
5. Lower the wiper arm. Wheels
Clean the wheels as you would the
rest of the exterior. Wash them with
the same solution, and rinse them
thoroughly.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum from corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stiff
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a soft brush or sponge.

To safely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inflated.
The following pages give more
detailed information on how to take
care of your tires and what to do
when they need to be replaced.
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.Inflation Guidelines
Keeping the tires properly inflated
provides the best combination of
handling, tread life, and riding
comfort.
●Underinflated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.●Overinflated tires can make your
vehicle ride more harshly, are
more prone to damage from road
hazards, and wear unevenly.
The tire pressure monitoring system
(TPMS) will warn you when a tire
pressure is low. See page 390 for
information on the TPMS. 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 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf/cm
2) per
month. Remember to check the
spare tire at the same time.
Check the air pressures when the
tires are cold. This means the vehicle
has been parked for at least 3 hours,
or driven less than 1 mile (1.6 km).
Add or release air, if needed, to
match the recommended cold tire
pressures.
Tires44411/06/16 17:42:51 12 ACURA RDX MMC North America Owner's M 50 31STK650 enu
Page 451 of 518

If you check air pressures when the
tires are hot (driven for several
miles/kilometers), you will see
readings 4 to 6 psi (30 to 40 kPa, 0.3
to 0.4 kgf/cm
2) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air pressure. The tire will be
underinflated.
You should get your own tire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier for 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
for punctures if a tire starts losing
pressure. Recommended Tire Pressures
The following charts show the
recommended cold tire pressures for
most normal driving conditions.
Tire Size Cold Tire Pressure
for Normal Driving
P235/55R18 99V Front/Rear:
32 psi (220 kPa ,
2.2 kgf/cm
2)
The compact spare tire pressure is:
60 psi (420 kPa , 4.2 kgf/cm
2)
For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver's doorjamb.
For additional information about your
tires, see page 484. Tire Inspection
Every time you check inflation, you
should also examine the tires for
damage, foreign objects, and wear.
You should look for:
●Bumps or bulges in the tread or
side of the tire. Replace the tire if
you find either of these conditions.●Cuts, splits, or cracks in the side of
the tire. Replace the tire if you can
see fabric or cord.●Excessive tread wear.

Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 1/2
inch (12.7 mm) wide band across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread left on
the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.Tire Service Life
The service life of your tires is
dependent on many factors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inflation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use).
In addition to your regular
inspections and inflation pressure
maintenance, it is recommended that
you have annual inspections
performed once the tires reach five
years old. It is also recommended
that all tires, including the spare, be
removed from service after 10 years
from the date of manufacture,
regardless of their condition or state
of wear.
The last four digits of the TIN (tire
identification number) are found on
the sidewall of the tire and indicate
the date of manufacture (See
Tire
Labeling on page 484). Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
Have your dealer check the tires if
you feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comfort and tire life. For best results,
have the installer perform a dynamic
balance.
Improper wheel weights can damage
your vehicle's aluminum wheels. Use
only Acura wheel weights for
balancing.

Tire RotationTo help increase tire life and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.Replacing Tires and Wheels
Replace your tires with radial 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 vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a different
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
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 affect wheel speed and may
cause the ABS or VSA system to
activate.
It is best to replace all four tires at
the same time. If that is not possible
or necessary, replace the two front
tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle's handling.
If you ever replace a wheel, make
sure that the wheel's specifications
match those of the original wheels.
Also be sure you use only TPMS
specific wheels. If you do not, the tire
pressure monitoring system will not
work.
Replacement wheels are available at
your dealer.

Installing improper tires on your
vehicle 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.Wheel and Tire Specifications

See page 482 for information about
DOT Tire Quality Grading, and page
484 for tire size and labeling
information. Winter Driving
Tires marked
‘‘M + S’’ or ‘‘All
Season ’’on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best performance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.
Snow Tires
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
may be lower than your original tires.
Check with the tire dealer for
maximum speed recommendations.

Page 455 of 518

Tire Chains
Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
front tires.
Because your vehicle has limited tire
clearance, Acura strongly
recommends using the chains listed
below, made by Security Chain
Company (SCC).
Cable type: Shur Grip Z
SZ343When installing cables, follow the
manufacturer's instructions, and
mount them as tight as you can.
Make sure they are not contacting
the brake lines or suspension. Drive
slowly with them installed. If you
hear them coming into contact with
the body or chassis, stop and
investigate. Remove them as soon as
you begin driving on cleared roads.
Traction devices that are the wrong size
or improperly installed can damage
your vehicle's brake lines, suspension,
body, and wheels. Stop driving if they
are hitting any part of the vehicle.
Using the wrong chains, or not
properly installing chains, can
damage the brake lines and
cause a crash in which you can
be seriously injured or killed.
Follow all instructions in this
owner's manual regarding the
selection and use of tire chains.

Check the condition of the battery
monthly by looking at the test
indicator window. The label on the
battery explains the test indicator's
colors.Check the terminals for corrosion (a
white or yellowish powder). To
remove it, cover the terminals with a
solution of baking soda and water. It
will bubble up and turn brown. When
this stops, wash it off with plain
water. Dry off the battery with a cloth
or paper towel. Coat the terminals
with grease to help prevent future
corrosion.
If additional battery maintenance is
needed, see your dealer or a
qualified technician.
WARNING:
Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash your hands after handling.
If you need to connect the battery to
a charger, disconnect both cables to
prevent damaging your vehicle's
electrical system. Always disconnect
the negative (- ) cable first, and
reconnect it last.
The battery gives off explosive
hydrogen gas during normal
operation.
A spark or flame can cause the
battery to explode with enough
force to kill or seriously hurt
you.
Wear protective clothing and a
face shield, or have a skilled
technician do the battery
maintenance.
