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 about 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 active
driving 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 the 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.
