2007 Acura MDX VSA

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 of the same size
and type as your original tires (see
page ).
When VSA is off, the VSA activation
indicator comes on as a reminder.
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.
With the VSA off, the trailer stability
assist function is also turned off (see
page ).
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.
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.413

Under these conditions, trailer
stability assist begins to stabilize the
vehicl e/trailer combination by
reducing the vehicle speed. The
control unit sends signals to
selectively apply the brakes and
regulate the engine output. The
brake lights of your vehicle will be
turned on automatically by the
system even if you do not keep the
pressu re on the brake pedal.
Your
vehicle is equipped with trailer
stability assist function. This
function works on the same sensors
as the vehicle stability assist (VSA)
system. This function helps to
stabilize the vehicl e/trailer
combination when the trailer
severely sways or oscillates. For
more information of the VSA system,
see page .
When the brakes are applied, the
trailer’s brake lights come on along
wi th the vehicle brake lights.
When the trailer stability assist
activates, you will see the VSA
activation indicator blink. There may
also be some noise from the VSA
hydraulic system. Trailer
stability assist cannot prevent
a loss of control. Always reduce the
ve hicle speed and steer firmly. Do
not brake suddenly or make quick
steering motion. It could cause the
trailertojackknifeorturnoverand
the system becomes ineffective.
Trailer stability assist cannot prevent
swaying that can occur in crosswinds
and in normal and emergency
driving maneuvers. It helps only to
stabilize the vehicl e/trailer
combination in these conditions,
after the oscillation becomes severe.
If
the function detects the vehicle/
trailer instability, it checks if the
swaying is caused by the trailer, and
if the trailer swaying or oscillation is
increasing.
The vehicle/trailer combination is
more affected by crosswinds,
buffeting, and improper tongue load.
These conditions can make the
trailer unstable, and cause it to sway. Always obey the recommended
speed limits f or towing a trailer, see
page . Trailer stability assist will also be
inef f ective while driving at high
speed or towing a trailer with a high
center or gravity.

IfyouturnofftheVSA,thetrailer
stability assist function also shuts off.
Press and hold the VSA off switch
until you hear a beep (see page ).
The VSA activation indicator comes
on as a reminder. Press and hold the
switch again to turn the system on.
The function turns on every time you
start the engine along with the VSA,
even if you turned it off the last time
you drove the vehicle.
The control unit monitors the VSA
circuitry and the braking system. If
there is a problem with the brake
lighting system, the trailer stability
assist function shuts down and the
‘‘CHECK TRAILER STABILITY
ASSIST’’ message appears on the
multi-info rmation display.
If you see this message, have your
vehicle checked at your dealer as
soon as possible. In
this case, your vehicle still has the
VSA traction and stability
enhancem ent, but it will not have the
trailer stability assist function.

To help increase tire lif e 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 diagram each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.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 dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently.
TheABSworksbycomparingthe
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 system to
activate.It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.
If you ever replace a wheel, make
sure that the wheel’s specif ications
match those of the original wheels.
Also be sure you use only TPMS
specif ic wheels. If you do not, the
tire pressure monitoring system will
notworkonthattire.
Replacement wheels are available at
your Acura dealer.

The brake system indicator
norm ally comes on when
you turn the ignition switch
to the ON (II) position, and
as a reminder to check the
parking brake. It will stay
on if you do not fully
release the parking brake.
If the brake system indicator comes
on while driving, the brake fluid level
is probably low. Press lightly on the
brake pedal to see if it feels normal.
If it does, check the brake fluid level
thenexttimeyoustopataservice
station (see page ). Slow
down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible.
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicato r, have your
vehicle inspected by your dealer
immediately.
You will also see a ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inform ation display (see page ).
If
the fluid level is low, take the
vehicle to your dealer and have the
brake system inspected for leaks or
worn brake pads.
However, if the brake pedal does not
feel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit
design will still give you braking at
two wheels. You will feel the brake
pedal go down much farther before
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
You will also see a ‘‘LOW BRAKE
FLUI D’’ message on the multi-
info rmation display (see page ).
