●When the VSA system indicator
comes on (see page 473).●When you turn the ignition switch
to the ON (II) position, the CMBS
indicator should come on for a few
seconds, then go off. If the
indicator comes on at any other
time and a CHECK CMBS
SYSTEM message appears on the
multi-information display, there is
a problem with the CMBS. You
can still drive your vehicle, but
CMBS will not be operating. Have
your vehicle checked by a dealer.Limitations
The CMBS may not activate under
some conditions. Here are a few
examples:
●The distance between your vehicle
and the vehicle ahead of you is too
short.●A vehicle cuts in front of you at a
slow speed, or it brakes suddenly.
●When you accelerate rapidly and
approach the vehicle ahead of you
at high speed.●Immediately after you begin
driving.

●Driving in heavy, stop-and-go
traffic.●The vehicle ahead of you is a
motorcycle or other small vehicle.
●A vehicle suddenly crosses in front
of you.The CMBS is not designed to detect
pedestrians.This system is designed to detect
and provide sufficient advanced
warning of a collision. As a result,
you may experience occasional false
activations.
Even with little or no chance of a
collision, the CMBS may activate
under these conditions:
●When you change lanes quickly,
and go around the vehicle ahead of
you.

Because of the road condition
(curved, winding, etc.) or the state of
your vehicle (turning angle, lane
position, etc.), CMBS can sometimes
mistake a stationary object (light
pole, traffic sign, guard rail, etc.) as a
vehicle ahead of you and temporarily
operate. This is normal.Important Safety Reminder
The main purpose of the CMBS is to
reduce the severity of injuries caused
by an unavoidable collision. While
the CMBS may help to alert you and
minimize the severity of a collision, it
may not activate in every dangerous
situation.
Even with the CMBS, it is still your
responsibility to operate the brake
pedal and steering wheel
appropriately, according to the
driving conditions.This device complies with the
appropriate requirements or the
required standards. See page 592 for
more information.

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surfaces. It does this by
regulating the engine's output and by
selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise from the VSA
hydraulic system. You will also see
the VSA system indicator blink.
The VSA system cannot enhance the
vehicle's driving stability in all
situations and does not control your
vehicle's entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
VSA Off Indicator
When VSA is off, the VSA off
indicator comes on as reminder.Vehicle Stability Assist
(VSA) System Indicator
When VSA activates, you will see the
VSA system indicator blink.
If this indicator comes on while
driving, pull to the side of the road
when it is safe, and turn off the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
NOTE:The main function of the VSA
system is generally known as
Electronic Stability Control (ESC).
The system also includes a traction
control function.If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.

You will also see a‘‘CHECK VSA
SYSTEM’’message on the multi-
information display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on, or the multi-
information display shows a‘‘CHECK
TPMS SYSTEM’’message with the
indicator flashing (see page 458), the
VSA system automatically turns on
even if the VSA system is turned off
by pressing the VSA OFF button. If
this case, you cannot turn the VSA
system off by pressing the VSA OFF
button again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.VSA Off Button
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 off
indicator comes on as a reminder.
Press and hold the switch again. It
turns the system back on. With the
VSA off, the trailer stability assist
function is also turned off (see page
498).
VSA is turned on every time you start
the engine, even if you turned it off
the last time you drove the vehicle.
