Precautions For Using Acc

Failure to follow the warnings and instructions for proper use of the ACC system could result in serious injury or death.

• ACC is not a self-driving system. Within the limits of its capabilities, as described in This information, it helps the driver with certain driving activities.
• The ACC system is not a replacement for proper driving procedures and is not designed to correct careless, inattentive or absent-minded driving. The ACC system is not designed to prevent loss of control. It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
• There are limitations to the ACC system capability. The ACC system does not function in all driving, traffic, weather, and road conditions. It is the driver's responsibility to stay alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
• The ACC system is only an aid to assist the driver and is not a collision warning or avoidance device.
• The ACC system is for highway use only and is not intended for city driving. Failure to apply the brakes or steer the vehicle when necessary may result in a serious accident.
• Always observe posted speed limits and do not set the speed over them.
• Never take hands off the steering wheel when driving. Always keep hands on the steering wheel and drive the vehicle safely.
• Never unfasten the seat belt when using ACC.
• The ACC system does not react when approaching stationary and slow moving vehicles.
• Always drive carefully and attentively when using the ACC system. Read and understand the Owner's Manual thoroughly before using the ACC system. To avoid serious injury or death, do not rely on the system to prevent accidents or to control the vehicle's speed in emergency situations. Do not use the ACC system except in appropriate road and traffic conditions.

When the accelerator pedal is depressed and the vehicle approaches the vehicle ahead, the ACC system neither controls the brake nor warn the driver with the buzzer and display. The driver must manually control the vehicle speed to maintain a safe distance to the vehicle ahead. Failure to do so could result in severe personal injury or death.

To prevent the vehicle from moving or rolling unexpectedly, which could result in serious personal injury or property damage, before exiting the vehicle make sure to push the ACC switch to turn the system off, push the park button to shift to the P (Park) position, and turn the engine off.

In order to reduce the risk of a collision that may result in serious injury or death, please be aware of the following:

• Acceleration when passing function is only activated with the left turn signal and briefly accelerates the vehicle even if a lane change is not initiated. This can include non-passing situations such as left side exits.
• Ensure that when passing another vehicle, the adjacent lane is clear before initiating the pass. Sudden changes in traffic may occur while passing. Always manually steer or brake as needed. Never solely rely on the system.

Listed below are the system limitations for the ACC system. Failure to operate the vehicle in accordance with these system limitations could result in serious injury or death:

• The ACC system does not adapt automatically to road conditions. This system should be used in evenly flowing traffic. Do not use the system on roads with sharp curves or on icy roads, in heavy rain or in fog.
• As there is a performance limit to the distance control function, never rely solely on the ACC system. This system does not correct careless, inattentive or absentminded driving or overcome poor visibility in rain, fog, or other bad weather. Decelerate the vehicle speed by depressing the brake pedal, depending on the distance to the vehicle ahead and the surrounding circumstances in order to maintain a safe distance between vehicles.
• Always pay attention to the operation of the vehicle and be ready to manually control the proper following distance. The ACC system may not be able to maintain the selected distance between vehicles (following distance) or selected vehicle speed under some circumstances.
• The ACC system does not detect the following objects:
  • Stationary or slow moving vehicles (when the vehicle is approaching them)
  • Pedestrians or objects in the roadway
  • Oncoming vehicles in the same lane
  • Motorcycles traveling offset in the travel lane
• The ACC system may not detect a vehicle ahead in certain road, weather or driving conditions. To avoid accidents, never use the ACC system under the following conditions:
  • On roads with heavy, high-speed traffic or sharp curves
  • On slippery road surfaces such as on ice or snow, etc.
  • On a bumpy road surface, such as an uneven dirt road
  • On steep downhill roads (the vehicle may go beyond the vehicle set speed and frequent braking may result in overheating the brakes)
  • On repeated uphill and downhill roads
  • During bad weather (rain, fog, snow, etc.)
  • When the sensor detection is reduced (conditions such as rain, snow, fog, dust storms, sandstorms, and road spray from other vehicles)
  • When dirt, ice, snow or other material adhere to the radar sensor area
  • When traffic conditions make it difficult to keep a proper distance between vehicles because of frequent acceleration or deceleration
  • When a complicated-shaped vehicle such as a car carrier trailer or flatbed truck/trailer is near the vehicle ahead
  • When there is interference by other radar sources
  • When excessively heavy baggage is loaded in the rear seat or cargo area of the vehicle
  • When towing a trailer or other vehicle
• In some road or traffic conditions, a vehicle or object can unexpectedly come into the sensor detection zone and cause automatic braking. Always stay alert and avoid using the ACC system where not recommended in this warning information.
• The ACC system also uses a multi-sensing front camera. The following are some conditions in which the camera may not properly detect a vehicle and detection of a vehicle ahead may be delayed:
  • Poor visibility (conditions such as rain, snow, fog, dust storms, sandstorms, and road spray from other vehicles)
  • The camera area of the windshield is fogged up or covered with dirt, water drops, ice, snow, etc.
  • Strong light (for example, sunlight or high beams from oncoming vehicles) enters the front camera
  • A sudden change in brightness occurs (for example, when the vehicle enters or exits a tunnel or shaded area or lightning flashes)
• Excessive noise interferes with the warning buzzer sound, and the beep may not be heard.
• For the ACC system to operate properly, the windshield in front of the camera must be clean. Replace worn wiper blades. The correct size wiper blades must be used to help make sure the windshield is kept clean. Only use Mitsubishi Genuine wiper blades, or equivalent wiper blades, that are specifically designed for use on the vehicle model and model year.
• Cruise control mode (fixed speed), a warning buzzer does not sound to warn the driver if you are too close to the vehicle ahead, as neither the presence of the vehicle ahead nor the vehicle-to-vehicle distance is detected.
• Pay special attention to the distance between the vehicle and the vehicle ahead or a collision could occur.
• Always confirm the setting in the ACC system display.
• Do not use the conventional (fixed speed) cruise control mode when driving under the following conditions. Doing so could cause a loss of vehicle control and result in an accident.
  • When it is not possible to keep the vehicle at a set speed
  • In heavy traffic or in traffic that varies in speed
  • On winding or hilly roads
  • On slippery roads (rain, snow, ice, etc.)
  • In very windy areas

To avoid accidentally engaging cruise control, make sure to turn the ACC switch off when not using the ACC system.
