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.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.This switch is under the lef t vent.
Press it to turn the vehicle stability
assist system on and of f .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. 182

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 to work inconsistently.
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.
Move the tires to the positions
shown in the illustration each time
they are rotated. If you purchase
directional tires, rotate only f ront-to-
back.
To help increase tire lif e and
distribute wear more evenly, rotate
the tires at these intervals:

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

Check with the tire dealer f or
maximum speed recommendations. 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. Tires marked ‘‘M S’’ or ‘‘All
Season’’ on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.

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.

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).
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 the
compact spare tire.
Do not use the compact spare tire
if you are towing a trailer.
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.
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.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
On models with manual
transmission, do not drive f or a
long period with the compact
spare tire mounted on a f ront
wheel; it will damage the limited
slip dif f erential. Turn of f the VSA system (see
page ). Driving with the
compact spare tire may activate
the VSA system.182
