2-4. Using other driving systems
Example of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration
When there are no longer vehicles driving slower than the set speed
in the lane ahead
When the vehicle ahead of you executes a lane change, the system slowly
accelerates until the set vehicle speed is reached. The system then returns to
fixed speed cruising.
Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic deceleration via th e cruise control is not po ssible, the display will
flash and buzzer will sound to alert th e driver. An example of this would
be if another driver cuts in front of you while you are following a vehicle.
Apply the brakes to ensure an appr opriate vehicle-to-vehicle distance.
■Warning lights, messages and buzzer s for dynamic radar cruise control
Warning lights, messages and buzzers are us ed to indicate a system malfunction or
to inform the driver of the need for caution while driving. ( P. 4 6 3 )
■Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-vehicle
distance control mode has been used. Th e mode also cannot be switched from
constant speed control to vehicle-to-vehic le distance control mode. Turn the sys-
tem off by pressing the “ON-OFF” button, and turn it on again.
■The dynamic radar cruise can be set when
●The shift lever is in the D position. However, it cannot be set if any of the ranges 1
through 3 has been selected using the paddle shift switches.
●Vehicle speed is more than approximately 30 mph (50 km/h).

●When passing an oncoming vehicle on a curve
●When driving over a narrow iron bridge
●When there is a metal object on the road surface
●When driving on an uneven road surface
●When passing an oncoming vehicle on a left-turn
●When your vehicle rapidly closes on the vehicle in front

●When climbing a steep hill causes an over head billboard or other metallic struc-
ture to appear directly in the vehicle's line of travel.
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
●When passing through certain toll gates
When the system is activated in the situations described above there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten.
■When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. ( P. 4 5 3 , 4 6 3 )

●On roads with sharp be nds or uneven surfaces
●On slippery roads such as those covered with ice or snow
●If a vehicle suddenly moves in front of your vehicle, such as at an intersection
