Do not apply a strong force to an ultrasonic sensor (rear):
When washing the vehicle, do not spray highly pressurized water against an ultrasonic sensor
(rear), or rub it strongly. In addition, do not hit the rear bumper forcefully when loading and
unloading cargo Otherwise, the sensors may no t detect obstructions correctly which could
cause the SCBS R system to not operate no rmally, or it could operate unnecessarily.
CAUTION
When driving off-road in areas where there is gr ass or foliage, it is recommended that the
SCBS R system be turned off.
 Always use tires of the specified size and th e same manufacturer, brand, and tread pattern
on all 4 wheels. In addition, do not use tires with significantly different wear patterns on the
same vehicle. Otherwise, the SCBS R system may not operate normally.
 If ice or snow is stuck on the ultrasonic sensors (rear) they may not be able to detect
obstructions correctly depending on the conditions. In such cases, the system may not be
able to perform controls correctly. Always dr ive carefully and pay attention to the rear of
the vehicle.
NOTE
The vehicle posture changes depending on the accelerator pedal, brake pedal and
steering wheel operations, which could make it difficult for the system to recognize an
obstruction, or it could facilitate unnecessary detection. In such cases, the SCBS R may or
may not operate.
The SCBS R system will operate under the following conditions.
The engine is running.
The selector lever is in the R (reverse) position.
“Reverse Smart City Brake Support Malfunction” is not displayed in the
multi-information display.
The vehicle speed is between about 2 to 8 km/h (2 to 4 mph).
The SCBS R is not turned off.
The DSC is not malfunctioning.
The SCBS R operates using ultrasonic sensors (rear) which detect obstructions at the rear
by emitting ultrasonic waves and then receiving the returning waves reflected off the
obstructions.
In the following cases, the ultrasonic sensors (rear) cannot detect obstructions and the
SCBS R may not operate.
The height of the obstruction is low such as low walls or trucks with low loading
platforms.
The height of the obstruction is high such as trucks with high loading platforms.

The obstruction is soft such as a hanging curtain or snow stuck to a vehicle.
The obstruction is shaped irregularly.
The obstruction is extremely close.
In the following cases, the ultrasonic sensors (rear) cannot detect obstructions correctly
and the SCBS R may not operate.

collision.
The vehicle is affected by other sound waves such as the horn, engine noise, ultrasonic
sensor of another vehicle.
In the following cases, an ultrasonic sensor (rear) may detect something as a target
obstruction which could cause the SCBS R system to operate.
Driving on a steep slope.
Wheel blocks.
Hanging curtains, gate poles such as at toll gates and railroad crossing.
When traveling near objects such as foliage, barriers, vehicles, walls, and fences along
a road.

To increase speed using accelerator
pedal
Depress the accelerator pedal to accelerate
to the desired speed. Press the SET/
switch and release it immediately.
NOTE
Accelerate if you want to speed up
temporarily when the cruise control is on.
Greater speed will not interfere with or
change the set speed. Take your foot off
the accelerator to return to the set speed.
▼To Decrease Cruising Speed
Press the SET/ switch and hold it. The
vehicle will gradually slow.
Release the switch at the desired speed.

Press the SET/
switch and release it
immediately to adjust the preset speed.
Multiple operations will decrease the
preset speed according to the number of
times it is operated.

speed indicated in km /h: 1 km/h (0.6 mph)
Instrument cluster display for vehicle
speed indicated in mph: 1 mph (1.6 km/h)
▼ To Resume Cruising Speed at More
Than 25 km/h (16 mph)
If the cruise control system temporarily
canceled (such as applying the brake
pedal) and the system is still activated, the
most recent set speed will automatically
resume when the RES/
switch is pressed.
If vehicle speed is below 25 km/h (16
mph), increase the vehicle speed up to 25
km/h (16 mph) or more and press the RES/
switch.

The selector lever is in the P or N
position.
When the cruise control system is
temporarily canceled by even one of the
applicable cancel conditions, the speed
cannot be re-set.
The cruise control cannot be cancelled
while driving in manual mode (selector
lever shifted from D to M position).
Therefore, engine braking will not be
applied even if the transaxle is shifted
