deceleration that is not a sudden braking
operation.

■
when
● The limits of tire gripping performance
have been exceeded (such as exces-
sively worn tires on a snow covered
road).
● The vehicle hydroplanes while driving
at high speed on wet or slick roads.
■ Stopping 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 main-
tain a safe distance from the vehicle in
front of you, especially in the following
situations:
● When driving on dirt, gravel or snow-
covered roads
● When driving with tire chains
When driving over bumps in the road
●
When driving over roads with potholes
●
or uneven surfaces
TRC/VSC may not operate effec-
■
tively when
Directional control and power may not
be achievable while driving on slippery
road surfaces, even if the TRC/VSC sys-
tem is operating.
Drive the vehicle carefully in conditions
where stability and power may be lost.
Active Cornering Assist does not
■
operate effectively when
Do 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.

●
quently operates, Active Cornering
Assist may temporarily stop operating
to ensure proper operation of the
brakes, TRC and VSC.
■ Hill- start assist control does not
operate effectively when
Do not overly rely on hill-start assist

control. Hill-start assist control may
not operate effectively on steep
inclines and roads covered with ice.
● Unlike 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.
■ When the TRC/VSC is activated
The slip indicator light flashes. Always
drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
When the TRC/VSC systems are
■
turned off
Be especially careful and drive at a speed
appropriate to the road conditions. As
these are the systems to help ensure
vehicle stability and driving force, do not
turn the TRC/VSC systems off unless
necessary.
