WARNING
Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis
roller or being towed:
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation
when the vehicle is running on a chassis roller or being towed. See the next page on
how to turn off the Smart City Brake Support (SCBS).
Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page
4-143 .
CAUTION
  When driving off-road in areas where there is grass or forage, it is recommended that
the Smart City Brake Support (SCBS) system be turned off.
  Always use tyres for all wheels that are of the specifi ed size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tyres with signifi cantly
different wear patterns on the same vehicle as the Smart City Brake Support (SCBS)
system may not operate normally.
  The laser sensor (front) includes a function for detecting a soiled windscreen and
informing the driver, however, depending on the conditions, it may not detect plastic
shopping bags, ice or snow on the windscreen. In such cases, the system cannot
accurately determine a vehicle ahead and may not be able to operate normally. Always
drive carefully and pay attention to the road ahead.
NOTE
  The Smart City Brake Support (SCBS) system will not operate if the driver is
deliberately performing driving operations (accelerator pedal and steering wheel).
  The Smart City Brake Support (SCBS) system will operate under the following
conditions.
 


 The engine is running.



 The Smart City Brake Support (SCBS) warning light (amber) does not illuminate.



 The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).



 The Smart City Brake Support (SCBS) system is not turned off.



 The DSC is not malfunctioning.

When Driving
i-ACTIVSENSE
NOTE
  The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-
infrared laser beam and receiving the beam refl ected off the refl ector of the vehicle
ahead, and then using it for the measurement. Consequently, the Smart City Brake
Support (SCBS) may not operate under the following conditions:
 


 Refl ection of the laser is poor due to the shape of the vehicle ahead.



 The vehicle ahead is signifi cantly dirty.



 Under bad weather condition, such as rain, fog and snow.



 The window washer is being used or the windscreen wipers are not used when it's
raining.
 


 The windscreen is dirty.



 The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
 


 Trucks with low loading platforms and vehicles with an extremely low or high
profi le.




 Vehicles with certain shapes such as a vehicle carrier. 

 Under the following conditions, the Smart City Brake Support (SCBS) system may not
operate normally.
 


 Heavy luggage is loaded in the luggage compartment or on the rear seat.



 If there is the possibility of partial contact with a vehicle ahead.



 When driving on continuously curving roads, and entering and exiting exits.



 Elongated luggage or cargo is loaded onto installed roof rails and covers the laser
sensor (front) .
 


 Exhaust gas from the vehicle in front, sand, snow, and water vapour rising from
manholes and grating, and water splashed into the air.
 


 When towing a malfunctioning vehicle.



 When driving with tyres having signifi cantly different wear. 

 In the following cases, the laser sensor (front) may inadvertently determine that there
is a vehicle ahead and the Smart City Brake Support (SCBS) system may operate.
 


 Objects on the road at the entrance to a curve.



 Vehicles passing in the opposite lane while making a curve.



 Metal objects, bumps, or protruding objects on the road.



 When passing through a toll gate equipped with a bar.



 When passing under a vinyl curtain or fl ag.



 Plastic objects such as pylons.



 Two-wheeled vehicles, pedestrians, animals or standing trees. 

(Manual transaxle) If the vehicle is stopped by the SCBS operation and the clutch pedal is not depressed,
the engine stops.

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 speed you want.
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

To Resume Cruising Speed at
More Than 25 km/h (16 mph)
If some other method besides the OFF
switch was used to cancel cruising speed
(such as applying the brake pedal) and the
system is still activated, the most recent
set speed will automatically resume when
the RESUME 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
RESUME switch.
To Temporarily Cancel
To temporarily cancel the system, use one
of these methods:
 


 Slightly depress the brake pedal.



(Manual transaxle)
 Depress the clutch pedal.



 Press the CANCEL switch.
If the RESUME switch is pressed when
the vehicle speed is 25 km/h (16 mph) or
higher, the system reverts to the previously
set speed.
NOTE
  If any of the following conditions
occur, the cruise control system is
temporarily cancelled.
 


 The parking brake is applied.



(Vehicles with adjustable speed
limiter)
  The ON/OFF switch for the
adjustable speed limiter is pressed.
 


(Automatic transaxle)
 The selector lever is in the P or N
position.
 


(Manual transaxle)

 When the cruise control system is
temporarily cancelled by even one of
the applicable cancel conditions, the
speed cannot be re-set.
 (Automatic transaxle) 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 down
to a lower gear. If deceleration is
required, lower the set speed or
depress the brake pedal.
