Acura RDX 2007 Owner's Manual

The anti-lock brake system (ABS)
helps prevent the brakes from
locking up, and helps you retain
steering control by pumping the
brakes rapidly, much faster than a
person can do it.
The ABS also balances the front-to-
rear braking distribution according
to vehicle loading.
Let the ABS work for you by always
keeping firm, steady pressure on the
brake pedal. This is sometimes
referred to as ‘‘stomp and steer.’’ You
will feel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal: it is the ABS rapidly
pumpingthebrakes.Ondry
pavement, you will need to press on
thebrakepedalveryhardbeforethe
ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice. If
this indicator comes on, the anti-
lock function of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible.
You will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
inf ormation display (see page ). 85
You should never pump the brake pedal. On RDX with Technology Package

If the ABS indicator and the brake
system indicator come on together,
and the parking brake is fully
released, the front-to-rear braking
distribution system may also be shut
down.
Test your brakes as instructed on
page . If the brakes f eel normal,
drive slowly and have your vehicle
repaired by your dealer as soon as
possible. Avoid sudden hard braking
which could cause the rear wheels to
lock up and possibly lead to a loss of
control.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving. Al
though your tire pressure is
monito red, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when cold, and
set to the recommended inflation
pressure as specified on the vehicle
placard and in the owner’s manual
(see page ).
Driving on a signifi cantly under-
inflated tire causes the tire to
ov erheat and can lead to tire failure.
Under-infl ation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability. When
the low tire pressure indicator
is on, one or more of your tires is
signifi cantly underinflated. You
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure as indicated on
the vehicle’s tire information placard.
Each
tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure indicator to come on.
With this indicator on, you will see
which tire is losing the pressu re on
the multi-information display along
with a ‘‘CHECK TIRE PRESSU RE’’
message (see page ).
With

Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure indicator may
come on unexp ectedly.
For example, if you check and fill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure
indicator to come on. Or, if you
check and adjust your tire pressure
in cooler conditions, and drive into
extremely hot conditions, the tire
maybecomeoverinflated.However,
the low tire pressure indicator will
not come on if the tires are
overinflated.
Refer to page for tire inflation
guidelines. This
indicator comes on and stays on
if there is a problem with the tire
pressure monitoring system.
If this happens, the system will shut
off and no longer monitor tire
pressures. Have the system checked
by your dealer as soon as possible. If
you have a flat tire, the low tire
indicator and tire pressure monitor
will come on. Replace the indicated
flat tire with the compact spare tire
(see page ).
After you replace the flat tire with
the spare, the low tire pressure
indicator stays on. This is normal;
the system is not monitoring the
spare tire pressure. Manually check
the spare tire pressure to be sure it
is correct.
Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.

Each wheel is equipped with a tire
pressure sensor mounted inside the
tire behind the valve stem. You must
use TPMS specific wheels. It is
recommended that you always have
your tires serviced by your dealer or
qualified technician.
Your vehicle has a tire pressure
monitor on the info rmation display. The
tire pressure monitor uses the
same display as the door and tailgate
open monitor. When any of the tires
has low pressure, the low tire
pressure indicator on the instrument
panel comes on, and you will also see
which tire is losing the pressu re on
the tire pressure monitor.
If the TPMS indicator comes on, the
tire pressure monitor does not work
(see page ).
If the low tire pressure indicator and
the low tire position on the low tire
pressure monitor do not go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible. 73

If one or more tires have low
pressure, the low tire pressure
indicator on the instrument panel
also comes on (see page ).
It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure
indicator and message on the multi-
inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.
When the TPMS is functioning
normally, you can see the tire
pressure readings of each tire in psi
(U.S. models) or kPa (Canadian
models) by pressing the SEL/
RESET button while the multi-
inf ormation display shows the tire
pressure monitor. If there is a problem with the TPMS,
the multi-information display shows
a ‘‘CHECK TPMS SYSTEM’’

The VSA system cannot enhance the
vehicle’s driving stability in all
situ ations 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.
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. You will also see
the VSA activation indicator blink. When
VSA activates, you will see the
VSA activation indicator blink (see
page ).
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 deale r.
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 vehic le as
soon as possible. You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
inf ormation display (see page ).
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.
When you put a spare tire on the
wheel, TPMS indicator or ‘‘CHECK
TPMS SYSTEM’’ message
(depending on the models) may
come on. When the indicator or
message is on, you are unable to turn
of f the VSA system with the VSA
OFF switch.

This switch is under the driver’s side
vent. To turn the VSA system on and
off, press and hold it until you hear a
beep.
When VSA is off, the VSA activation
indicator comes on as a reminder.
VSA is turned on every time you
start the engine, even if you turn ed it
off the last time you drove the
vehicle. Driving
with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are the same size
and type as your original tires (see
page ).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system
is of f , the traction control system is
alsooff.Youshouldonlyattemptto
f ree your vehicle with the VSA of f if
you are not able to f ree it when the
VSA is on.
Immediately af ter f reeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
