Driving
■Automatic shutoff
The CMBSTM may automatically shut itself off and the safety support indicator
(amber) comes and stays on when:
• You drive off-road or on a mountain ro ad, or curved and winding road for an
extended period.
• Driving in bad weather (rain, fog, snow, etc.).
• Driving with the parking brake applied.
• The camera temperature gets too high.
• The front of the camera is covered by dirt, fog, rain, mud, wet snow, seals,
accessories, stickers, or film on the windshield.
• An abnormal tire condition is detected (i ncorrect tire size, flat tire, etc.).
Once the conditions that caused the CMBS
TM to shut off improve or are addressed
(e.g., cleaning), the system comes back on.

Low Speed Braking Control*
Using sonar sensors located on the front a nd rear bumpers, and the front grille, this
system can detect if there is danger of a potential collision with a wall or other
obstacle during normal driving or when the accelerator pedal is depressed with too
much force. The system then assists in avoiding collisions and reducing damage
from impact through assistive braking a nd/or assistive driving power suppression.1Low Speed Braking Control*
If the Low Speed Braking Control activates in a
situation where you do not want automatic brake
application (such as when the vehicle is between two
railroad crossing gates), simply press the brake pedal
to deactivate the system and then continue to drive
as intended.
3WARNING
The Low Speed Braking Control System
cannot avoid all collisions and may not
reduce damage in each situation where the
accelerator is mistakenly or aggressively
pressed. Overreliance on the system may
result in a collision with serious injury or
death. Always check your surroundings,
your shift position, and your pedal use.
Driver remains responsible for safely
operating the vehicle.

■Assistive braking
Assistive braking provides a visual and audible alert when the vehicle is moving
between approximately 1 and 6 mph (2 and 10 km/h) and there is the possibility of
a collision with a detected wall or other obstacles, as well as providing assistance
with braking.

sensors, please refer to the following page.

Conditions for assistive driving power suppressionM
• When the accelerator is no longer depressed.
• When the accelerator is depresse d for approximately four seconds.
• When the brake pedal is depressed.
Conditions for assistive braking cancellation.
• A certain amount of time has passed since activation.
The system may not operate correctly in the following conditions:
■Examples of obstacles the sonar sensor cannot detect
• Obstacles that do not reflect sound waves well, such as people, snow, cloth,
sponges, etc.
• Thin obstacles such as fenc es, bicycles, sign posts, etc.
• Short or small obstacles.
• Obstacles immediately in front of the bumper.
• Moving objects or obstacles that suddenly enter the road.
• Obstacles that are not perp endicular to the ground.
■Conditions for Cancellation
■Low Speed Braking Control System Conditions and Limitations
1Conditions for Cancellation
After Low Speed Braking Control has activated once,
it will not activate again for the same obstacle.
They can be activated again after driving for a certain
distance after last activation.
Low Speed Braking Control ac tivates separately when
moving forward and reversing. (For example, if it
activates when moving forwar d, it can be activated
again immediately if reversing.)
However, if assistive braking has been activated, in
order to activate assistiv e driving power suppression
again, it is necessary to drive for a certain distance to
reset the system.

Adaptive Cruise Control (ACC) with Low Speed Follow
Helps maintain a constant vehicle speed and a set following-interval behind a vehicle
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate
and stop your ve hicle, without you having to keep your foot on the brake or the
accelerator.
When ACC with Low Speed Follo w slows your vehicle by applying the brakes, your
vehicle’s brake lights will illuminate.
• Vehicle speed for ACC wi th Low Speed Follow: A vehicle is detected ahead
within ACC with Low Speed Follow range – ACC with Low Speed Follow
operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with Low Speed Follow range – ACC
with Low Speed Follow operates at th e speed of 25 mph (40 km/h) or above.

Use ACC with Low Speed Follow only
when driving on expressways or freeways
and in good road and weather conditions.
3WARNING
ACC with Low Speed Follow has limited
braking capability and may not stop your
vehicle in time to avoid a collision with a
vehicle that quickly stops in front of you.
Always be prepared to apply the brake

DrivingWhen driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press the RES/+/SET/− switch up or down when you reach the desired
speed. The moment you release the switch, the set speed is fixed, and ACC with Low
Speed Follow begins.
When driving slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pressing the switch fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If your vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.
■To Set the Vehicle Speed1 Adaptive Cruise Control (ACC) with Low Speed Follow
Do not use ACC with Low Speed Follow under the
following conditions:
•On roads with frequent la ne change or continuous
stop and go traffic, ACC with Low Speed Follow
cannot keep an appropriate distance between your
vehicle and the vehicle ahead of you.
•On roads with sharp turns.•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
•On roads with bad weather (rain, fog, snow, etc.),
ACC with Low Speed Follow may not detect the
distance between your vehicle and the vehicle
ahead of you properly.
•On roads with slippery or icy surfaces. The wheels
may spin out and your vehi cle may lose the control
on the condition.
•On roads with steep uphill or steep downhill slopes.
•On roads with undulating slopes.

When a vehicle whose sp eed is slower than
your set speed is detected in front of you, your
vehicle starts to slow down.1 When in Operation
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC with Low Speed
Follow may start accelerati ng your vehicle under the
following circumstances:
•The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.
•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly increasing the interval
between the vehicles.
You can also set the system to beep when a vehicle in
front of you comes in and goes out of the ACC with
Low Speed Follow detecting range. A vehicle detect

■There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your ve hicle from traveling at
the set speed, ACC with Low Speed Follow
accelerates your vehicle to the set speed, and
then maintains it.
On steep downhill during ACC with Low
Speed Follow, it brakes to inhibit excessive
acceleration for maintaining the set speed.
However, the vehicle speed may become
faster than the set speed.
■When you depress the accelerator pedal
You can temporarily increase the vehicle speed . In this case, there is no audible or
visual alert even if a vehicle is in the ACC with Low Speed Follow range.
ACC with Low Speed Follow stays on unle ss you cancel it. Once you release the
accelerator pedal, the system resume s an appropriate speed for keeping the
following-interval while a vehicle ahead is within the ACC with Low Speed Follow
range.
1 When in Operation
•ACC with Low Speed Follow may temporarily
control the interval between your vehicle and the
vehicle in adjacent lane or surroundings of your
vehicle depending on the road conditions (e.g.
curves) or vehicle condi tions (e.g. operating the
steering wheel or the vehicle location in the lane).
•When the vehicle ahead of you moves away, such
as when entering an interchange or rest area, ACC
with Low Speed Follow may continue to maintain
the set following-interval for a short time.
A vehicle icon with line contour
appears on the gauge.
