High Beam Control System (HBC)*
The HBC determines the conditions in front of the vehicle using the Forward Sensing
Camera (FSC) while driving in darkness to automatically switch the headlights between
high and low beams.
Refer to Warning/Indicator Lights on page 4-42.
While driving the vehicle at a speed of about 30 km/h (19 mph) or more, the headlights are
switched to high beams when there are no vehicles ahead or appr oaching in the opposite
direction.
The system switches the headlights to low beams when one of the following occurs:
•The system detects a vehicle or the headlights/lights of a vehicle approaching in the
opposite direction.
•The vehicle is driven on roads lin ed with streetlamps or on roads in well-lit cities and
towns.
•The vehicle is driven at less than about 20 km/h (12 mph).
Forward Sensing
Camera (FSC)
The recognition distance of the
Forward Sensing Camera (FSC)
varies according to the
surrounding conditions.
The warning light turns on when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-42.
CAUTION
Do not adjust the vehicle he ight, modify the headlight units, or remove the camera,
otherwise the system will not operate normally.
Do not rely excessively on the HBC and drive the vehicle while paying
sufficient attention to
safety. Switch the headlights between th e high beams and low beams manually if
necessary.

Long, descending slopes (to maintain distance between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)
Slopes with a steep gradient (The vehicle ahea d may not be detected correctly, your vehicle
may slide while stopped by the stop hold control, and it may accelerate suddenly after it
starts moving.)
For safety purposes, switch the MRCC system off when it is not being used.
CAUTION
If your vehicle is towed or you are towing some thing, switch the MRCC system off to prevent a
miss-operation.
NOTE
•The MRCC 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 travelling at an extre mely low speed, the system may not detect it
correctly.
•During headway control travel, do not set the system for detection of two-wheeled
vehicles such as motorcycles and bicycles.
•Do not use the MRCC 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 system is in use, it does not cancel even if the selector lever (automatic
transaxle)/shift lever (manual transaxle) is operated and any intended engine braking will
not occur. If deceleration is required, lower the vehicle speed setting 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 automatic braking is operating, however, they
may not turn on while the vehicle is on a downslope at the set vehicle speed or travelling
at a constant speed and following a vehicle ahead.

Roads with sharp curves and where vehicle
traffic is heavy and there is
insufficient space
between vehicles.
Roads where frequent and repetitive accelerati on and deceleration occur (Driving under
these conditions using the MRCC with Stop & Go function system is not possible).
When entering and exiting interchanges, servic e areas, and parking areas of highways (If
you exit a highway while headway control is in use, the vehicle ahead will no longer be
tracked and your vehicle may accelerate to the set speed).
Slippery roads such as ice or snow-bound roads (Tyres could spin causing you to lose
vehicle control, or the stop hold control may not operate.)
Long, descending slopes (to maintain distance between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)
Slopes with a steep gradient (The vehicle ahea d may not be detected correctly, your vehicle
may slide while stopped by the stop hold control, and it may accelerate suddenly after it
starts moving.)
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 co ntrol 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 electric parking brake (EPB).
CAUTION
If your vehicle is towed or you are towing something, switch the MRCC with Stop & Go
function system off to prevent a miss-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 travelling at an extre mely low speed, the system may not detect it
correctly.
•During headway control travel, do not set the system for detection of two-wheeled

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 Sens ing 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 se nsor (front) and the Forward
Sensing Camera (FSC) determines that a collision is unavoidable, the automatic brake
control is performed to reduce d amage in the event of a collision.
In addition, when the driver depresses the brake pedal, the bra kes 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 ev ent of a collision, not avoid an accident. The
ability to detect an obstruction is limited de pending on the obstruction, weather conditions,
or traffic conditions. Therefore, if the accelerator pe
dal or brake pedal is mistakenly operated
it could result in an accident. Always verify th e safety of the surrounding area and depress the
brake pedal or accelerator pedal while keepin g a safer distance from vehicles ahead or
on-coming vehicles.
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.
NOTE
•The SBS system operates when all of the following conditions are met:
•The ignition is switched ON.
•The SBS system is on.
•The vehicle speed is about 15 km/h or faster (10 mph or faster).
•The relative speed between your vehicle and the vehicle ahead is about 15 km/h or
faster (10 mph or faster).
•The Dynamic Stability Control (DSC) is not operating.
•The SBS system may not operate under the following conditions:
•If the vehicle is accelerated rapidly and it comes cl ose to a vehicle ahead.
