When Driving
i-ACTIVSENSE
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 tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent 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 windshield and informing
the driver, however, depending on the conditions, it may not detect plastic shopping bags,
ice or snow on the windshield. 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 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.
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 windshield wipers are not used when it's
raining.
The windshield is dirty.
