the 4 wheels from spinning when starting
the vehicle or accelerating on slippery roads, or in off-road conditions
◆Hill-start assist control (if equipped)
Helps to prevent the vehicle from rolling backward when starting on an incline or slip-
pery slope
◆KDSS (Kinetic Dynamic Suspension System)
KDSS helps to enhance ride comfort and ha ndling response by using a hydraulic con-
trol system to control the suspension stabiliz er bars in response to road surface and
driving conditions during cornering or off-road driving
◆PCS (Pre-Collision system) (if equipped)
 P. 3 6 2
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake pressure for indi-
vidual wheels and reducing engine to rque when trailer sway is detected.

rolling backward when starting on an
incline, or if any of the drive wheels
spins, the slip indicator light flashes to

■Automatic cancelation of pre-collision system
When a malfunction occurs due to sensor cont
aminations, etc. that results in the sensors
being unable to detect obstacles, the pre-collision syst em will be automatically disabled.
In this case, the system will not activate even if there is a collision possibility.
■Obstacles not detected
The system cannot detect plastic obstacles su ch as pylons. There may also be occasions
when the system cannot detect pedestrians, animals, bicycles, motorcycles, trees, or
snowdrifts.
■Conditions that may trigger the system even if there is no possibility of a collision
●When there is an object by the roadside at the entrance to a curve
●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface (nose up, nose down)
●When passing an oncoming vehicle on a left turn
●When your vehicle rapidly closes on the vehicle in front
●When a grade separation/interchange, sign, billboard, or other structure appears to be
directly in the vehicle’s line of travel
●When a billboard or other metallic structure appears to be in the direct line of travel
due to driving on a hill
●When there are excessive changes in the vehicl e height (when it tilts forwards or back-
wards)
●When the axis of the radar is out of adjustment
●When passing through certain toll gates
●When passing through an overpass
●When passing through a tunnel
When the system is activated in the situations described above, there is also a possibility
that the seat belts will retrac t quickly and the brakes will be applied with a force greater
than normal. When the seat belt is locked in the restricted position, stop the vehicle in a
safe place, release the seat belt and refasten it.
■When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights will turn on or flash, an d warning messages will be displayed.
