Driving
Vehicle Stability AssistTM (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 select ively 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 brake system. You will also see the
indicator blink.
■VSA ® Operation
1 Vehicle Stability AssistTM (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 ma y 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 Stability Control (ESC). The
system also includes a traction control function.

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 and a message on the multi-information
display informs you that the mode is changed.
Traction control mode cannot be changed
during Mud or Sand modes. If you are driving
on mud or sand, Mud or Sand Intelligent
Traction Management modes can also be
used to free a stuck ve hicle. On other road
surfaces, change to Normal or Snow mode,
then press and hold the (VSA ® OFF )
button.
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 AssistTM (VSA® ), aka Electronic Stability Control
(ESC), System
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.

Driving
Intelligent Variable Torque Management (i-VTM4TM)
AWD System*
The Intelligent Variable To rque Management (i-VTM4TM) AWD System is a full time
all wheel drive system that automatically controls and transfers varying amount of
engine torque to all wheels independently according to the driving conditions.
You still need to exercise the same care when accelerating, steering, and braking
that you would in a two wheel drive vehicle.
Avoid continuously driving on slippery surfaces where a wheel is likely to spin out,
and do not drive if the All-wheel drive ( AWD) Indicator starts blinking. Driving
continuously under such conditions can damage the system’s torque distribution
unit.
If the All-wheel drive (AWD ) Indicator blinks while driving, it indicates the
differential temperature is too high. If this happens, pull to the side of the road
when it is safe, shift to park, and idle the engine until the indicator goes out. If the
indicator does not go out, take your vehi cle to a dealer to have it checked.1Intelligent Variable Torq ue Management (i-VTM4TM) AWD
System*
NOTICE
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause transmission or re ar differential damage.
The Intelligent Variable Torque Management (i-
VTM4
TM) 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. 522
