How to Set the Distance Between Vehicles During Headway Control
The distance between vehicles is set to a shorter distance each time the
switch is pressed.
The distance between vehicles is set to a longer distance by pressing the
switch. The
distance-between-vehicles can be set to 4 levels; Long, medium, short, and extremely short
distance.

Distance-between-vehicles guideline
(at 80 km/h (50 mph) vehicle speed) Display
Long (about 50 m (164 ft))


Medium (about 40 m (131 ft))


Short (about 30 m (98 ft))


Extremely short (about 25 m (82 ft))



NOTE
  The distance between vehicles differs depending on the vehicle speed, and the slower
the vehicle speed, the shorter the distance.
  When the ignition is switched to ACC or OFF and then the engine is started again, the
system automatically sets the distance between vehicles to the previous setting.

Cruise Control Function
While this function is operating, the
headway control operation is cancelled
and only the cruise control function
operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise control function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WARNING
Do not use the cruise control function
in the following locations:
Otherwise, it could lead to an accident.
 
 Roads with sharp curves and where
vehicle traf¿ c is heavy and there is
insuf¿ cient space between vehicles.
(Driving under these conditions
using the cruise control function is
not possible)
  Steep down slopes (Set speed may be
exceeded because suf¿ cient engine
braking cannot be applied)
  Slippery roads such as ice or snow-
bound roads (Tyres could spin
causing you to lose vehicle control)

Always drive carefully:
The warnings and brake control
will not operate after the headway
control function is cancelled and the
system is switched to only the cruise
control function. Depress the brake
pedal to decelerate according to the
surrounding conditions while keeping
a safer distance from the vehicle ahead
and always driving carefully.

and the cruise main indication (white) is
turned on.

WARNING
Always turn off the cruise control
function when it is not in use:
Leaving the cruise control function
turned on when it is not in use
is dangerous as it could operate
unexpectedly, resulting in an accident.
