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.
xThe lowest possible speed which can be set on the MRCC with Stop & Go
function system is 30 km/h (19 mph).
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.
How to set the distance-between-vehicles during headway control
The distance-between-vehicles can be set to 4 levels; Long, medium, short, and
extremely short distance.
The distance-between-vehicles is set to a shorter distance by pressing the CANCEL
switch down. The distance-between-vehicles is set to a longer distance by pressing
the CANCEL switch up.

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
indication (green) switches to the
MRCC with Stop & Go function
standby indication (white) at the same
time.

operates, the MRCC with Stop & Go
function indicator light turns on.
NOTE
xIf the MRCC with Stop & Go
function system is cancelled during
stop hold control, the vehicle is held
in its stopped position.
xThe parking brake is automatically
applied and the vehicle is held in its
stopped position when 10 minutes
have elapsed since the stop hold
control operated. At this time, the
MRCC with Stop & Go function
system is cancelled.
xIf the i-stop operation conditions are
met during stop hold control, the
engine stops even though the brake

Cruising & Traffic Support
(CTS)
*
▼Cruising & Traffic Support (CTS)
The CTS is a system which consists of a
headway control function and a
steering assist function for reducing
driver fatigue during traffic jams when
driving on expressways or highways.
This system performs headway control
to maintain a constant distance
between your vehicle and a vehicle
ahead at a preset vehicle speed
without you having to use the
accelerator or brake pedal. Even
further, with the steering assist
function, when vehicle lane lines are
detected, the function assists the driver
in keeping the vehicle within the lane
lines. If lane lines are not detected, the
function provides the driver driving
assistance in keeping the vehicle along
the motion path with the vehicle
ahead.
WARNING
Do not rely completely on CTS:
¾The CTS is not an automated driving
system. In addition, the functions
have limitations. Do not rely
completely on the system and always
stay on course using the steering
wheel.
¾Set a vehicle speed within the speed
limit according to the road
conditions and the weather
conditions.
