Mazda CX-9 Owners Manual: 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.

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 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 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.
  • Stationary objects (stopped vehicles, obstructions)

Indication on Display

The DRSS operation status is indicated in the active driving display or multi-information display. Regarding malfunctions, check the vehicle conditions or have it inspected by an Authorized Mazda Dealer according to the content of the displayed message.

NOTE

• When the ignition is switched off, the operation status before the system was turned off is maintained. For example, if the ignition is switched off with the DRSS operable, the system will be operable when the ignition is switched ON the next time.
• The DRSS can be turned on/off and the system's sensitivity can be changed.
