Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
Deactivate the VSA system if you
need to drive with the compact spare
tire installed (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.
When VSA is off, the VSA activation
indicator comes on as a reminder.
If the indicator does not come on
when the ignition switch is turned to
ON(II),theremaybeaproblem
with the VSA system. Have your
dealer inspect your vehicle as soon
as possible.
This switch is under the lef t vent.
Press it to turn the VSA system on
and off. 255

Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common f or boat
trailers, since the brakes will get wet.
If you choose electric brakes, be
sure they are electrically actuated.
Do not attempt to tap into your
vehicle’s hydraulic system. No
matter how successf ul it may seem,
any attempt to attach trailer brakes
to your vehicle’s hydraulic system
will lower braking ef f ectiveness and
create a potential hazard.
See your brake manuf acturer f or
more inf ormation on installing
electric brakes.Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but do not let the
chains drag on the ground.
This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
Many states and provinces require
special exterior mirrors when towing
a trailer. Even if they don’t, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.When towing a trailer, we
recommend that you carry a f ull-size
spare wheel and tire for your vehicle
and trailer. See page f or proper
tire size, page f or how to store a
full size wheel and tire, and page
f or inf ormation on changing a
flat tire.
Remember to unhitch the trailer
bef ore changing a f lat. Ask your
trailer sales or rental agency where
and how to store the trailer’s spare
tire. 255

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.
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).
Also be sure you use only TPMS
specif ic wheels. If you do not, your
Tire Pressure Monitoring System
will not work on that tire.
Replacement wheels are available at
your Acura dealer.Wheel:

See page f or DOT tire quality
grading inf ormation, and page
f or tire size explanation.
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.

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.

´
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 perf ormance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions.
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as original tires. Mount snow tires on
all f our wheels. The traction
provided by snow tires on dry roads
maybelowerthanyouroriginaltires.
Check with the tire dealer f or
maximum speed recommendations. Because your vehicle has limited tire
clearance, mount only SAE Class ‘‘S’’
cable-type traction devices, with
rubber chain tensioners on the f ront
tires. Do not use any chains on rear
wheels. Use traction devices only
when required by driving conditions
or local laws. Make sure they are the
correct size f or your tires. Metal link-
type ‘‘chains’’ should not be used.
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
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.

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 inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:
Follow these precautions:Never exceed 50 mph (80 km/h)
under any circumstances.
This tire gives a harsher ride and
less traction on some road sur-
f aces. Use greater caution while
driving. Do not mount snow chains on a
compact spare.
Do not use the compact spare tire
if you are towing a trailer.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
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.
