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

■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.
