■Automatic cancellation
The beeper sounds and a message app ears on the MID when ACC with LSF is
automatically canceled. Any of these co nditions may cause the ACC with LSF to
automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC with LSF range is too close to your
vehicle.
• When a detected vehicle goes out of th e ACC with LSF range while your vehicle
is stationary.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation can be also triggered by the following
causes. In these cases, the electric park ing brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicl e is stationary.
• The vehicle stops for mo re than 10 minutes.
• The engine is turned off.

uuWhen Driving uVehicle Stability Assist (VSA® ), aka Electronic Stability Control (ESC), System
Driving
Vehicle Stability Assist (VSA®), aka Electronic
Stability Control (ESC), System
VSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine output and selectively applying the brakes.
When VSA® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehi cle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stab ility Control (ESC). The
system also includes a traction control function.

Driving
This button is on the driver side control panel.
To partially disable VSA ® functionality/
features, press and hold it until you hear a
beep.
The traction control stop s fully functioning,
allowing the wheels to spin more freely at low
speed. The VSA ® OFF indicator will also come
on.
To restore VSA ® functionality/features, press
the (VSA ® OFF) button until you hear a
beep.
VSA ® is turned on every time you start the
engine, even if you turned it off the last time
you drove the vehicle.
■VSA ® On and Off1 Vehicle Stability Assist (VSA ®), aka Electronic Stability Control
(ESC), System
With the button pressed, your vehicle will have
normal braking and corn ering ability, but VSA®
traction and stability enhancement becomes less
effective.
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the button is pressed, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA ® off if
you are not able to free it when the VSA ® is on.
Immediately after freeing your vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® system switched off.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.

Agile Handling Assist System
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehi cle’s stability and performance during
cornering.1 Agile Handling Assist System
The agile handling assist system cannot enhance
stability in all driving situat ions. You still need to drive
and corner at speeds appr opriate for the conditions
and always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist system
does not activate.
You may hear a sound coming from the engine
compartment while the system is activated. This is
normal.

uuWhen Driving uSuper Handling-All Wheel DriveTM (SH-AWD ®)*
Driving
Super Handling-Al l Wheel DriveTM (SH-AWD®)*
The system controls and trans fers varying amounts of engine torque to each wheel
in accordance with the driving conditions.
SH-AWD ® helps to enhance driving stability, and lets you handle situations like
slippery surfaces, such as snow, sand, mud, and steep hills, better than when driving
with two wheel drive. Howeve r, the system does not help to enhance braking. Be
precautious about the following:
• It is still your responsibility to drive sa fely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.1Super Handling-All Wheel DriveTM (SH-AWD ®)*
NOTICE
Avoid continuously driving in sand or mud where a
wheel is likely to spin out, and do not drive once the
SH-AWD ® indicator starts blinking. Driving
continuously under such conditions can damage the
system’s torque distribution unit.
Do not drive through deep water.
The SH-AWD ® system may not function properly if
tire type and size are mixed.
Make sure to use the same size and type of tire, and
the air pressures as specified. 2 Tire and Wheel Replacement P. 496
