When Driving
i-ACTIVSENSE
For safety purposes, switch the MRCC with
Stop & Go function system off when it is not
being used.
Do not get out of the vehicle while the stop
hold control is operating:
Getting out of the vehicle while the stop
hold control is operating is dangerous as
the vehicle may move unexpectedly and
result in an accident. Before getting out of
the vehicle, switch the MRCC with Stop &
Go function system off, shift the selector
lever to the P position, and apply the
parking brake.
CAUTION
If your vehicle is towed or you are towing
something, switch the MRCC with Stop &
Go function system off to prevent an
unexpected operation.
NOTE
The MRCC with Stop & Go function

system does not detect the following as
physical objects.
Vehicles approaching in the opposite

direction
Pedestrians

Stationary objects (stopped vehicles,

obstructions)
If a vehicle ahead is traveling at an

extremely low speed, the system may
not detect it correctly.
If there is a structure on the road or an

object (such as a monorail) at a low
height off the ground in front of the

Do not use the MRCC with Stop & Go

function system under conditions in
which close proximity warnings are
frequently activated.
During headway control travel, the

system accelerates and decelerates your
vehicle in conjunction with the speed of
the vehicle ahead. However, if it is
necessary to accelerate for a lane
change or if the vehicle ahead brakes
suddenly causing you to close in on the
vehicle rapidly, accelerate using the
accelerator pedal or decelerate using
the brake pedal depending on the
conditions.
While the MRCC with Stop & Go

function system is in use, it does not
cancel even if the selector lever is
operated and any intended engine
braking does not occur. If deceleration
is required, lower the set speed or
depress the brake pedal.
The sound of the automatic brakes

operating may be heard, however, it
does not indicate a problem.
The brake lights turn on while the

MRCC with Stop & Go function
automatic braking is operating.
