Depending on the road configura-
D
tion (curved, left and right continu-
ous curved, the start or end of a
curve, or narrow driving lanes due
to road construction) or your ve-
hicle condition (steering wheel ma-
neuvering, position in the lane, or
unstable driving because of an acci-
dent or breakdown), vehicles in oth-
er lanes or surrounding
may be detected, resulting in a con-
trol failure or the approach warning
activation. This may also result in
a very close distance between vehi-
cles due to a failure to detect the
vehicle ahead.

Dynamic laser cruise control should not
be used in circumstances which are inap-
propriate for any cruise control, such as
entering free way on−ramps or off−ramps.
CAUTION
Do not use dynamic laser cruise
D
control when exiting from or when
entering or merging onto a freeway.
When you are following a slower
moving vehicle and exiting, the sen-
sor does not detect the vehicle and
will accelerate to the preset speed.
05 SIENNA_U (L/O 0409)
If other vehicles are driving outside
D
of the laser radar detection range,
a delay in the detection of the ve-
hicle cutting in at short range or
failure to detect a motorcycle run-
ning on the side of the same lane
will occur. In this case, the dynamic
laser cruise control system will not
function properly.
When a slower vehicle in front of
D
you leaves the lane, the dynamic
laser cruise control will no longer
detect a vehicle ahead and will at-
tempt to accelerate the vehicle to
the faster preset speed.
