Toyota sienna 2004 Service Manual page 199

On roads with heavy traffic or
sharp bends, an appropriate speed
cannot be maintained and an acci-
dent may occur.
On slippery road surfaces (icy or
snow−covered road surfaces), the
tires will race and you will be un-
able to control the vehicle.
When there is no vehicle detected
ahead on steep downhill slopes, the
preset speed will be easily exceed-
ed because of inefficient engine
braking. (In this case, automatic
braking will not work.) If there is a
vehicle detected ahead, the delay in
deceleration timing could cause se-
rious injury or death.
When the alarm sounds frequently
(because acceleration or decelera-
tion was repeated or sufficient ve-
hicle−to−vehicle distance was not
maintained), an appropriate vehicle
speed cannot be attained and an
accident may occur.
04 SIENNA_U (L/O 0408)
On roads with steep and short in-
clines and declines, failure to de-
tect the vehicle ahead will shorten
the distance between your vehicle
and the vehicle ahead and an acci-
dent may occur.
D
Deceleration cruising function and
approach warning do not operate
when the vehicle ahead is at a stop
or driving very slowly.
D
If the vehicle ahead of you deceler-
ates abruptly or if another vehicle
cuts in ahead of you, your vehicle
may collide with the vehicle ahead
unless you manually depress the
brake pedal to slow down your ve-
hicle.

Depending on the road configura-
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 objects
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.
