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

your vehicle with the VSA and
traction control systems switched off.

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 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
ti res 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. 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
vehicleridemoreharshly,are
more prone to damage from road
hazards, and wear unevenly.

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.

To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the inf ormation display or multi-
inf ormation display (depending on
models). Move the tires to the
positions shown in the diagram each
time they are rotated. If you
purchase directional tires, rotate
only f ront-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 the new one matches the
specif ications of the original.
Replacement wheels are available at
your dealer.

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.

When installing cables, f ollow the
manuf acturer’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
youbegindrivingonclearedroads.
Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
f ront tires.
Because your vehicle has limited tire
clearance, Acura strongly
recommends using the chains listed
below, made by Security Chain
Company (SCC).

temporary replacement only. Get
your regular tire repaired or replaced,
and put it back on your vehicle as
soon as you can.

compact spare tire every time you
check the other tires. It should be
inf lated to: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 f or mounting a regular tire.
Follow these precautions:
