i-ACTIVSENSE*
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sensors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to assist the driver in safer driving by reducing the load on the
driver and helping to avert collisions or reduce their severity. However, because each system
has its limitations, always drive carefull y and do not rely solely on the systems.

Distance Recognition Support System (DRSS)*
The DRSS measures the distance between your vehicle and a vehicle ahead using a radar
sensor (front) while the vehicle speed is ab out 30 km/h (19 mph) or faster, and if your
vehicle approaches a vehicle ahead more closely than what is appropriate for maintaining
distance between the vehicles according to the vehicle speed, a notification in the
multi-information display is indicated to advise you to keep a safe distance from the vehicle
ahead.
WARNING
Do not rely completely on the DRSS and always drive carefully:
The ability to detect a vehicle ahead is limited depending on th e type of vehicle ahead, the
weather conditions, and the traffic conditions. Therefore, if the accelerator and brake pedals
are not operated correctly it could lead to an accident. Always verify the safety of the
surrounding area and depress the brake pedal or accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming vehicles.
NOTE
The DRSS operates when all of the following conditions are met:
The ignition is switched ON.
The DRSS is on.
The selector lever is in a po sition other than reverse (R).
The vehicle speed is 30 km/h or faster (19 mph or faster).
The objects which activate the system are 4-wheeled vehicles.
The DRSS may also operate in the presence of motorcycles and bicycles.
The DRSS may not operate normally under the following conditions:
The Dynamic Stability Control (DSC) has a malfunction.
The vehicle ahead is traveling at an extremely slow speed.
The system does not operate with the following objects:
Vehicles approaching in the opposite direction.
