have been exceeded (such as exces-
sively worn tires on a snow covered
road).
OThe vehicle hydroplanes while driving
at high speed on wet or slick roads.
QStopping distance when the ABS is
operating may exceed that of normal
conditions
The ABS is not designed to shorten the
vehicle’s stopping distance. Always
maintain a safe distance from the vehicle
in front of you, especially in the following
situations:
OWhen driving on dirt, gravel or snow-
covered roads
OWhen driving with tire chains
OWhen driving over bumps in the road
OWhen driving over roads with pot-
holes or uneven surfaces
QTRAC/VSC may not operate effec-
tively when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRAC/VSC
system is operating.
Drive the vehicle carefully in conditions
where stability and power may be lost.
QActive Cornering Assist does not
operate effectively when
ODo not overly rely on Active Corner-
ing Assist. Active Cornering Assist
may not operate effectively when
accelerating down slopes or driving on
slippery road surfaces.
OWhen Active Cornering Assist fre-
quently operates, Active Cornering
Assist may temporarily stop operating
to ensure proper operation of the
brakes, TRAC and VSC.
QHill-start assist control does not oper-
ate effectively when
ODo not overly rely on hill-start assist
control. Hill-start assist control may
not operate effectively on steep
inclines and roads covered with ice.
OUnlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended
period of time. Do not attempt to use
hill-start assist control to hold the vehi-
cle on an incline, as doing so may lead
to an accident.
QWhen the TRAC/ABS/VSC is acti-
vated
The slip indicator light flashes. Always
drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
QWhen the TRAC/VSC systems are
turned off
Be especially careful and drive at a
speed appropriate to the road condi-
tions. As these are the systems to help
ensure vehicle stability and driving force,
do not turn the TRAC/VSC systems off
unless necessary.
QSecondary Collision Brake
Do not rely solely upon the Secondary
Collision Brake. This system is designed
to help reduce the possibility of further
damage due to a secondary collision,
however, that effect changes according
to various conditions. Overly relying on
the system may result in death or serious
injury.
