CAUTION
n Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
l In heavy traffic
l On roads with sharp bends
l On winding roads
l On slippery roads, such as those covered with rain, ice and snow
l On steep downhills, or where there are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
l At entrances to expressways
l When weather conditions are bad enough that they may prevent the sen-
sors from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
l When an approach warning buzzer is heard often
n When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning (
→P. 230) will not be activated, and a fatal or serious
accident may result.
l Vehicles that cut in suddenly
l Vehicles traveling at low speeds
l Vehicles that are not moving
