*Some models.
Distance Recognition Support System (DRSS) *
The Distance Recognition Support System (DRSS) measures the distance between your
vehicle and a vehicle ahead using a radar sensor (front) while the vehicle speed is 30 km/h
or faster (19 mph or faster), and indicates a recommended distance to maintain between
the vehicles. Furthermore, if your vehicle approaches a vehicle ahead more closely than
the appropriate distance to maintain between the vehicles according to the vehicle speed,
the area between the vehicle-ahead indication and the vehicle indication in the multi-
information display fl ashes in white to advise the driver to keep a safer distance from the
vehicle ahead.
WARNING
Do not rely completely on the Distance Recognition Support System (DRSS) and always
drive carefully:
The Distance Recognition Support System (DRSS) provides advice for safer driving and
notifi es the driver of a recommended, safer distance to maintain with a vehicle ahead.
The ability to detect a vehicle ahead is limited depending on the type of vehicle ahead,
the weather conditions, and the traffi c 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 Distance Recognition Support System (DRSS) operates when all of the following
conditions are met:
The ignition is switched ON.
The Distance Recognition Support System (DRSS) is on.
The selector lever is in a position 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 Distance Recognition Support System (DRSS) may also operate in the presence of
motorcycles and bicycles.
The Distance Recognition Support System (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.
