*Some models.
Adjustable Speed Limiter *
The adjustable speed limiter is a function to prevent the vehicle from being driven at a
vehicle speed faster than a set speed. The vehicle speed is controlled to kept it below the set
speed even if the accelerator pedal is depressed.
The adjustable speed limiter can be set between 30 km/h (20 mph) and 200 km/h (125 mph).
The vehicle speed may exceed the set speed when the vehicle is driven on a down slope,
however, the system noti¿ es the driver by À ashing the display and operating a warning
sound.
WARNING
Always turn off the system when changing drivers:
If the driver is changed and the new driver is unaware of the adjustable speed limiter
function, the vehicle may not accelerate when the driver depresses the accelerator
pedal, leading to an accident.
The system consists of the adjustable speed limiter display and the speed limiter switch on
the steering wheel.

When Driving
i-ACTIVSENSE
NOTE
  The vehicle posture changes depending on the accelerator pedal, brake pedal and
steering wheel operations, which could make it dif¿ cult for the system to recognise an
obstruction, or it could facilitate unnecessary detection. In such cases, the Smart City
Brake Support [Reverse] (SCBS R) may or may not operate.
  The Smart City Brake Support [Reverse] (SCBS R) system will operate under the
following conditions.
 


 The engine is running.



 The change lever (manual transaxle vehicle) or the selector lever (automatic
transaxle vehicle) is in the R (reverse) position.
 


 The vehicle speed is between about 2 to 8 km/h (2 to 4 mph).



 The Smart City Brake Support [Reverse] (SCBS R) is not turned off.



 The DSC is not malfunctioning. 

 The Smart City Brake Support [Reverse] (SCBS R) operates using ultrasonic sensors
(rear) which detect obstructions at the rear by emitting ultrasonic waves and then
receiving the returning waves reÀ ected off the obstructions.

 In the following cases, the ultrasonic sensors (rear) cannot detect obstructions and the
Smart City Brake Support [Reverse] (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 small.



 The obstruction is thin such as a signpost.



 The obstruction is positioned away from the centre of the vehicle.



 The surface of the obstruction is not pointed vertically relative to the vehicle.



 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.

NOTE
  In the following cases, the ultrasonic sensors (rear) cannot detect obstructions correctly
and the Smart City Brake Support [Reverse] (SCBS R) may not operate.
 


 Something is stuck on the bumper near an ultrasonic sensor (rear).



 The steering wheel is turned sharply, or the brake or accelerator pedal is operated.



 There is another obstruction near one obstruction.



 During inclement weather such as rain, fog and snow.



 High or low humidity.



 High or low temperatures



 Strong winds.



 The path of travel is not À at.



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



 Objects such as a wireless aerial, fog light, or illuminated number plate is installed
near an ultrasonic sensor (rear).
 


 The orientation of an ultrasonic sensor (rear) has deviated for reasons such as a
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 Smart City Brake Support [Reverse] (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 travelling near objects such as foliage, barriers, vehicles, walls, and fences
along a road.
 


 When driving off-road in areas where there is grass and forage.



 When passing through low gates, narrow gates, car washing machines, and tunnels.



 A towing bar is installed or a trailer is connected. 

 (Manual transaxle)  If the vehicle is stopped by the SCBS operation and the clutch pedal is not depressed,
the engine stops.
  When the system operates, the user is noti¿ ed by the active driving display. 
 The Smart City Brake Support (SCBS) warning indication (amber) turns on when the
system has a malfunction.
 Refer to Warning Lights on page 4-36 .

When Driving
i-ACTIVSENSE
NOTE
  The Smart Brake Support (SBS) system operates when all of the following conditions
are met:
 


 The ignition is switched ON.



 The Smart Brake Support (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

 When the vehicle ahead is not equipped with tail lights or the tail lights are turned
off.
 


 When warnings and messages, such as a dirty windscreen, related to the Forward
Sensing Camera (FSC) are being displayed in the centre display.
 
 Although the objects which activate the system are four-wheeled vehicles, the radar
sensor (front) could detect the following objects, determine them to be an obstruction,
and operate the Smart Brake Support (SBS) system.
 


 Objects on the road at the entrance to a curve (including guardrails and snow banks).



 A vehicle appears in the opposite lane while cornering or rounding a curve.



 When crossing a narrow bridge.



 When passing under a low gate or through a tunnel or narrow gate.

Tyre Pressure Monitoring System
NOTE
Because this system detects slight changes in tyre conditions, the timing of the warning
may be faster or slower in the following cases:
 
 The size, manufacturer, or the type of tyres is different from the speci¿ cation. 
 The size, manufacturer, or the type of a tyre is different from the others, or the level of
tyre wear is excessively different between them.
  A run-À at tyre, studless tyre, snow tyre, or tyre chains are used. 
 An emergency tyre is used (The tyre pressure monitoring system warning light may
À ash and then continue illuminating).

 A tyre is repaired using the emergency À at tyre repair kit. 
 The tyre pressure is excessively higher than the speci¿ ed pressure, or the tyre pressure
is suddenly lowered for some reason such as a tyre burst during driving.
  The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle
is stopped), or the drive period is shorter than 5 minutes.
  The vehicle is driven on an extremely rough road or a slippery, icy road. 
 Hard steering and rapid acceleration/deceleration are repeated such as during
aggressive driving on a winding road.
  Load on the vehicle is applied to a tyre such as by loading heavy luggage to one side of
the vehicle.
  System initialization has not been implemented with the speci¿ ed tyre pressure.
