NOTE
xThe distance-between-vehicles differs depending on the vehicle speed, and the
slower the vehicle speed, the shorter the distance.
xWhen 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.
Changing the Set Vehicle Speed
(To accelerate/decelerate using the
RES switch)
When the RES switch is pressed up
(SET+), the vehicle accelerates and
when the RES switch is pressed down
(SET-), it decelerates.
xPress and release immediately: 1
km/h (1 mph)
xPress and hold: 10 km/h (5 mph)
(To increase speed using accelerator
pedal)
Depress the accelerator pedal and
press the RES switch up (SET+) or
down (SET-) at the desired speed. If
the switch is not operated, the system
returns to the set speed after you
release your foot from the accelerator
pedal.
NOTE
xThe warnings and brake control do
not operate while the accelerator
pedal is depressed.
x(European models)
When switching to a passing lane
and operating the direction
indicator, the system provides more
acceleration automatically if it
determines that more acceleration is
required. Drive while being careful of
the road ahead because you could
approach the vehicle ahead too
closely.
Cancelling the system
When the following operations are
performed, the MRCC with Stop & Go
function system is cancelled, and the
MRCC with Stop & Go function set

3. The headway control is operable when all of the conditions for it to operate are
met, or the steering assist function is operable when all of the conditions for it to
operate are met.
NOTE
xIf a vehicle ahead is detected while travelling at a constant speed, the
vehicle-ahead indication is displayed and headway control is performed.
Additionally, when a vehicle ahead is no longer detected, the vehicle-ahead
indication turns off and the system switches back to travel at constant speed.
xHeadway control is not possible if the vehicle ahead is driving faster than your
vehicle's set speed. Adjust the system to the desired vehicle speed using the
accelerator pedal.
xWhen the ignition is switched OFF, the system status before it was turned off is
maintained. For example, if the ignition is switched OFF with the CTS operable,
the CTS remains operational the next time the ignition is switched ON.
xWhen the CTS is operating, the Lane-keep Assist System (LAS), Distance & Speed
Alert (DSA), and Smart Brake Support (SBS) also turns on automatically.
