TPMS Acura RDX 2012 User Guide

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surfaces. It does this by
regulating the engine's output and by
selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise from the VSA
hydraulic system. You will also see
the VSA system indicator blink.
The VSA system cannot enhance the
vehicle's driving stability in all
situations and does not control your
vehicle's entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
VSA OFF Indicator
When VSA is off, the VSA OFF
indicator comes on as a reminder.Vehicle Stability Assist
(VSA) System Indicator
If this indicator comes on while
driving, pull to the side of the road
when it is safe, and turn off the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
NOTE : The main function of the VSA
system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control function. If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.
You will also see a
‘‘CHECK VSA
SYSTEM ’’message on the multi-
information display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on (see page 390),
or the multi-information display
shows a ‘‘CHECK TPMS SYSTEM ’’
message with the indicator flashing
(see page 393), the VSA system
automatically turns on even if the
VSA system is turned off with the
VSA OFF switch. In this case, you
cannot turn the VSA system off by
pressing the VSA OFF switch again.

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

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

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.

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or
replaced, and put it back on your
vehicle as soon as you can.
Check the inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
60 psi (420 kPa , 4.2 kgf/cm
2)Follow these precautions:
●Never exceed 50 mph (80 km/h).●This tire gives a harsher ride and
less traction on some road
surfaces. Use greater caution while
driving.●Do not mount snow chains on the
compact spare tire.●Do not use your compact spare tire
on another vehicle unless it is the
same make and model.●After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
After several miles (kilometers)
driving with the spare, this
indicator begins to flash, then
stays on again. You will also see a
‘‘
CHECK TPMS SYSTEM ’’
message on the multi-information
display (see page 393).
Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed for mounting a regular tire.

Glossary of Tire Terminology
Cold Tire Pressure－The tire air
pressure when the vehicle has been
parked for at least three hours or
driven less than 1 mile (1.6 km).
Load Rating －Means the maximum
load that a tire is rated to carry for a
given inflation pressure.
Maximum Inflation Pressure －The
maximum tire air pressure that the
tire can hold.
Maximum Load Rating －Means the
load rating for a tire at the maximum
permissible inflation pressure for that
tire.
Recommended Inflation Pressure －
The cold tire inflation pressure
recommended by the manufacturer.
Treadwear Indicators (TWI) －
Means the projections within the
principal grooves designed to give a
visual indication of the degrees of
wear of the tread. Tire Pressure Monitoring System
(TPMS)
－Required Federal
Explanation
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label.
(If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
those tires.) As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale
when one or more of your tires is
significantly under-inflated
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure.

Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Underinflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS
malfunction indicator is combined
with the low tire pressure telltale.
When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended.TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the
vehicle that prevent the TPMS from
functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.Tire Pressure Monitoring System (TPMS)
