Adaptive Cruise Control
Continued from previous page
Even when the following distance is short, the "brake more" warning may
not activate in the following cases.
- When the speed difference compared to the vehicle in front is small (the
two vehicles are travelling at almost the same speed)
- When the vehicle in front is traveling faster than your vehicle (the follow-
ing distance is gradually increasing)
- When another vehicle cuts into your lane very close to your vehicle
- When the vehicle in front decelerated suddenly
- When there are repeated uphill and downhill grades
After Adaptive Cruise Control has started, it maintains control continuously
according to the behavior of the vehicle in front. When your vehicle comes
to a stop because the vehicle in front has stopped, the automatic braking
function will be cancelled immediately after stopping and the vehicle will
start creeping forward gradually (at the same time three short beeps and a
single long beep will sound). Be sure to depress the brake pedal and stop
the vehicle completely.
Note that the vehicle is not maintained at a standstill position and will not
automatically start moving from a standstill position.
Braking may not be sufficient depending on the following conditions. Oper-
ate the brake pedal and decelerate as necessary.
- Vehicle conditions (amount of load, number of occupants, etc.)
- Road conditions (grade, slipperiness, shape, bumps, etc.)
- Vehicle maintenance status (brake systems, tire wear, air pressure, tem-
porary spare tire is being used, etc.)
- When the brakes are cold. (For example, just after the engine is started
or when the outside temperature is low.)
- For a short period of time when driving after the engine is started until the
engine has warmed-up
- When the brakes are overheated on downhill grades (braking effective-
ness may be reduced)
- When driving in rain or after washing the vehicle (the brakes may
become wet and braking effectiveness may be reduced)
- When the speed to potential obstacles is more than 20 MPH (30 km/h)
