Before Driving

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
page 545).
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.Hill Start Assist
Your vehicle is equipped with a hill
start assist feature to help prevent
the vehicle from rolling on steep
inclines as you move your foot from
the brake pedal to the accelerator.
This feature starts operating a few
seconds after you are in any drive
gear position (when faced uphill) or
in reverse (when faced downhill).
This feature requires that the vehicle
has come to a complete stop before it
can work.
Hill start assist may not hold a
heavily loaded vehicle, such as when
your vehicle is connected to a trailer,
or prevent your vehicle from rolling
downhill on a very steep or slippery
slope.
Vehicle Stability Assist (VSA
®), aka Electronic Stability Control (ESC), System
475
Driving

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, but the mode
may change temporarily to suit a
change in road surface.
To switch between comfort and sport
mode, press and release the active
damper system button located on the
center console to choose the desired
mode.
When comfort mode is selected, the
green indicator in the button comes
on, and the message‘‘COMFORT’’
will appear on the multi-information
display for five seconds.

Driving

To safely operate your vehicle, your
tires 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.
Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this
owner's manual regarding tire
inflation and maintenance.Inflation Guidelines
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
vehicle ride more harshly, are
more prone to damage from road
hazards, and wear unevenly.
The tire pressure monitoring system
(TPMS) warns you when a tire
pressure is low. See page 455 for
more information.
Even though your vehicle is
equipped with TPMS, we
recommend that you visually check
your tires every day. If you think a
tire might be low, check it
immediately with a tire gauge.Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf/cm
2) per
month. Remember to check the
spare tire at the same time.
Tires540

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.

Winter Driving

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.
