NOTE
In the following cases, the warnings and brakes may not operate even if your vehicle starts
closing in on the vehicle ahead.
You are driving your vehicle at the same speed as the vehicle ahead.
Directly after the MRCC with Stop & Go function system has been set.

All the doors are closed.
The driver's seat belt is fastened.
The selector lever is in the drive (D) pos ition or manual (M) position (manual mode).
NOTE
In the following cases, the MRCC with Stop & Go function system is canceled when the
vehicle is traveling at 30 km/h (20 mph) or less and “MRCC Disabled under 30 km/h (20
mph)” is displayed in th e active driving display.
The Forward Sensing Camera (FSC) cannot de tect target objects (There is problem
with the Forward Sensing Camera (FSC) or windshield is dirty).
There is a problem with the stop hold control function.
There is a problem with the electric parking brake (EPB).
It may not be possible to set the MRCC with Stop & Go f unction system directly after
starting the engine, while the DSC operation is being checked.

Advanced Smart City Brake Support (Advanced SCBS)*
The Advanced SCBS alerts the driver of a possible collision using the display and a warning
sound when the Forward Sensing Camera (FSC) detects a vehicle ahead or pedestrian and
determines that a collision with the object is unavoidable while the vehicle is driven at a
vehicle speed of about 4 to 80 km/h (2 to 50 m ph) if the object is a vehicle ahead and about
10 to 80 km/h (6.2 to 50 mph) if the object is a pedestrian. In addition, the system reduces
damage in the event of a collision by operating the brake control (Advanced SCBS brake)
when the system determines that a collision is unavoidable. In addition, when the driver
depresses the brake pedal, the brakes are appl ied firmly and quickly to assist. (Brake Assist
(Advanced SCBS brake assist))

Do not rely completely on the Advanced SCBS system:
 The Advanced SCBS system is only designed to reduce damage in the event of a collision.
Over reliance on the system leading to the accelerator pedal or brake pedal being
mistakenly operated could result in an accident.
 The Advanced SCBS system operates in respons e to a vehicle ahead, a 2-wheeled vehicle, or
a pedestrian. The system does not operate in response to obstructions such as a wall or
animals.

CAUTION
In the following cases, turn the system off to prevent a mis-operation:
 The vehicle is being towed or when towing another vehicle.
 The vehicle is on a chassis roller.
 When driving on rough roads such as in areas of dense grass or off-road.
Refer to Stopping the Advanced Smart City Brake Support (Advanced SCBS) System Operation
on page 4-118 on how to turn off the Advanced SCBS system.

The vehicle speed is between about 4 to 80 km/h (2 to 50 mph).
(Object is a pedestrian)
The vehicle speed is between about 10 to 80 km/h (6.2 to 50 mph).
The Advanced SCBS system is not turned off.
Under the following conditions, the Advan ced SCBS system may not operate normally:
The Advanced SCBS system will not operate if the driver is deliberately performing
driving operations (accelerator pedal and steering wheel).
If there is the possibility of partial contact with a vehicle ahead.
The vehicle is driven on a slippery road surface such as wet roads or icy or snow-bound
roads.
The braking performance is adversely affected due to cold temperatures or wet brakes.
The vehicle is driven at the same speed as the vehicle ahead.
The accelerator pedal is depressed.
The brake pedal is depressed.
The steering wheel is being operated.
The selector lever is being operated.
In the following cases, the Advanced SCBS may operate.
Objects on the road at the entrance to a curve.
Vehicles passing in the opposite lane while making a curve.
When passing through a toll gate.
When passing through low gates, narrow gates, car washing machines, or tunnels.
If you suddenly come close to a vehicle ahead.
2-wheeled vehicles, animals, or standing trees.

Smart City Brake Support (SCBS)*
The SCBS system alerts the driver of a possible collision using an indication in the display
and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle ahead and
determines that a collision with a vehicle ahead is unavoidable while the vehicle is being
driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system
reduces damage in the event of a collision by operating the brake control (Smart City Brake
Support (SCBS) brake) when the system determines that a collision is unavoidable while the
vehicle is being driven at a vehicle speed of about 4 to 30 km/h (2 to 18 mph). It may also
be possible to avoid a collision if the relative speed between your vehicle and the vehicle in
front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the
brake pedal while the system is in the operation range at about 4 to 30 km/h (2 to 18 mph),
the brakes are applied firmly and quickly to as sist. (Brake Assist (Smart City Brake Support
(SCBS) brake assist))

When the SCBS system is turned off, the
Smart City Brake Support (SCBS) OFF
indicator light turns on.

When the engine is restarted, the system
becomes operational.
Without SCBS OFF switch
Refer to Personalization Features on page
9-9.
NOTE
When the SCBS system is set to
inoperable, the Smart Brake Support
(SBS) are also set to inoperable.
With SCBS OFF switch
Press the SCBS OFF switch to turn off the
system. The Smart City Brake Support
(SCBS) OFF indicator light in the
instrument cluster will illuminate.
Press the switch agai n to turn the system
back on. The Smart City Brake Support
(SCBS) OFF indicator light will turn off.
Smart Brake Support
(SBS)
*
The SBS system alerts the driver of a
possible collision using a display and
warning sound if the radar sensor (front)
and the Forward Sensing Camera (FSC)
determine that there is the possibility of a
collision with a vehicle ahead while the
vehicle is being driven at about 15 km/h or
faster (10 mph or faster). Furthermore, if
the radar sensor (front) and the Forward
Sensing Camera (FSC) determines that a
collision is unavoidable, the automatic
brake control is pe rformed to reduce
damage in the event of a collision.
In addition, when the driver depresses the
brake pedal, the brakes are applied firmly
and quickly to assist. (Brake Assist (SBS
brake assist))
WA R N I N G
Do not rely completely on the SBS system
and always drive carefully:
The SBS is designed to reduce damage in
the event of a collision, not avoid an
accident. The ability to detect an
obstruction is limited depending on the
obstruction, weather conditions, or traffic
conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly
operated it could result in an accident.
Always verify the safety of the surrounding
area and depress the brake pedal or
accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming
vehicles.

Scheduled Maintenance (U.S.A., Canada, and Puerto
Rico)
Follow Schedule 1 if the vehicle is operated mainly where none of the following conditions
(severe driving conditions)apply.
Repeated short-distance driving
Driving in dusty conditions
Driving with extended use of brakes
Driving in areas where salt or other corrosive materials are used
Driving on rough or muddy roads
Extended periods of idling or low-speed operation
Driving for long periods in cold temperatures or extremely humid climates
Driving in extremely hot conditions
Driving in mountainous conditions continually
If any do apply, follow Schedule 2. (Canada residents follow Schedule 2.)
Vehicles using Engine Oil Flexible Maintenance
Engine Oil Flexible Maintenance is select ed by default for U.S.A. and Puerto Rico
residents.
If any following conditions do apply, follow Schedule 2 with engine oil fixed maintenance.
Extended periods of idling or low-speed opera tion such as police car, taxi or driving
school car
Driving in dusty conditions
The vehicle calculates the remaining oil life based on engine operating conditions. The
vehicle lets you know when an oil change is due by illuminating the wrench indicator light
in the instrument cluster. Change the oil as soon as possible within the next 1,000 km (600
mile) or 15 days. Refer to Maintenance Monitor on page 6-14 for the details.
NOTE
Please ensure that the Flexible Oil Maintenance Setting is reset after each Oil and Filter
replacement.
