VSA and Tire Sizes
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
page419).
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.
U.S. Sport Packages and Canadian ElitemodelsThe active damper system is always
on, constantly adjusting your
vehicle's dampers to the best settings
for current road conditions along
with vehicle speed and handling
inputs.
The system uses electrically
controlled dampers to enhance
handling precision, vehicle
composure, tire to road adhesion and
rough road ride comfort isolation.
The system reacts to inputs from
various electronic sensors to give
exactly the right amount of
suspension damping to provide
optimal ride comfort and handling. The system provides two selectable
modes.
Sport mode: The system prioritizes
handling response, vehicle body
control and tire-to-road adhesion to
allow for higher performance
handling.
Comfort mode: The system
prioritizes road isolation to allow for a
more comfortable ride.
Either mode can be used in any type
of operating conditions.

It is best to replace all four tires at
the same time. If that is not possible
or necessary, replace the two front
tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle's handling.
If you ever replace a wheel, make
sure that the wheel's specifications
match those of the original wheels.
Also be sure you use only TPMS
specific wheels. If you do not, the tire
pressure monitoring system will not
work.
Replacement wheels are available at
your dealer.
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.

See page454for information about
DOT Tire Quality Grading, and page
456for tire size and labeling
information. Winter Driving
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.
Snow Tires
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
may be lower than your original tires.
Check with the tire dealer for
maximum speed recommendations.
