  • The distance of the front vehicle on the instrument cluster appears according to the actual distance between your vehicle and the vehicle ahead.

  • The target distance may vary according to the vehicle speed and the set distance level. If the vehicle speed is low, even though the vehicle distance have changed, the change of the target vehicle distance may be small.

  • The images and colours in the instrument cluster may differ depending on the instrument cluster type or theme selected from the settings menu.

Accelerating temporarily

2C_SCCAcceleratingTemporarilyInfo

If you want to speed up temporarily without altering the set speed whilst Smart Cruise Control is operating, press the accelerator pedal. Whilst the accelerator pedal is pressed, the set speed, distance level and target distance blinks on the instrument cluster.

However, if the accelerator pedal is pressed insufficiently, the vehicle may decelerate.

Be careful when accelerating temporarily, because the speed and distance is not controlled automatically even if there is a vehicle in front of you.

Temporarily cancelling Smart Cruise Control

2C_SCCAutoTemporaryCancelingInfo

Smart Cruise Control will be temporarily cancelled automatically when:

  • The vehicle speed is above 210 km/h

  • The vehicle is stopped for a certain period of time

  • The accelerator pedal is continuously pressed for a certain period of time

  • The conditions for the Smart Cruise Control to operate are not satisfied

If Smart Cruise Control is temporarily cancelled automatically, the “Smart Cruise Control deactivated” warning message appears on the instrument cluster, and an audible warning sounds to warn the driver.

If Smart Cruise Control is temporarily cancelled whilst the vehicle is at a standstill with the function activated, EPB (Electronic Parking Brake) may be applied.

When Smart Cruise Control is temporarily cancelled, distance with the front vehicle will not be maintained. Always have your eyes on the road whilst driving, and if necessary, press the brake pedal to reduce your driving speed in order to maintain a safe distance.

Smart Cruise Control conditions not satisfied

In the following situation, the “Watch for surrounding vehicles” warning message appears on the instrument cluster, and an audible warning sounds to warn the driver of road conditions ahead.

  • The vehicle in front disappears when Smart Cruise Control is maintaining the distance with the vehicle ahead whilst driving below a certain speed.

Always pay attention for vehicles or objects that may suddenly appear in front of you, and if necessary, press the brake pedal to reduce your speed in order to maintain a safe distance.

Collision warning

2C_SCCCollisionWarningInfo

Whilst Smart Cruise Control is operating, when the collision risk with the vehicle ahead is high, the “Collision warning” warning message appears on the instrument cluster, and an audible warning sounds to warn the driver. Always have your eyes on the road whilst driving, and if necessary, press the brake pedal to reduce your driving speed in order to maintain a safe distance.

In the following situations, Smart Cruise Control may not warn the driver of a collision.

  • The distance from the front vehicle is short, or the vehicle speed of the front vehicle is faster or similar to your vehicle

  • The speed of the front vehicle is very slow or is at a standstill

  • The accelerator pedal is pressed immediately after Smart Cruise Control is turned on

Take the following precautions when using Smart Cruise Control:

  • Smart Cruise Control does not substitute for proper and safe driving. It is the driver's responsibility to always check the speed and distance to the vehicle ahead.

  • Smart Cruise Control may not recognise unexpected and sudden situations or complex driving situations, so always pay attention to driving conditions and control your vehicle speed.

  • Keep Smart Cruise Control off when the function is not in use to avoid inadvertently setting a speed.

  • Do not open the door or leave the vehicle when Smart Cruise Control is operating, even if the vehicle is stopped.

  • Always be aware of the selected speed and headway distance.

  • Keep a safe distance according to road conditions and vehicle speed. If the headway distance is too close during high-speed driving, a serious collision may result.

  • When maintaining distance with the vehicle ahead, if the front vehicle disappears, Smart Cruise Control may suddenly accelerate to the set speed. Always be aware of unexpected and sudden situations from occurring.

  • Vehicle speed may decrease on an upward slope and increase on a downward slope.

  • Always be aware of situations such as when a vehicle cuts in suddenly.

  • When you are towing a trailer or another vehicle, turn off Smart Cruise Control for safety reasons.

  • Turn off Smart Cruise Control when your vehicle is being towed.

  • Smart Cruise Control may not operate properly with interference from strong electromagnetic waves.

  • Smart Cruise Control may not detect an obstacle in front and lead to a collision. Always look ahead cautiously to prevent unexpected and sudden situations from occurring.

  • Vehicles moving in front of you with a frequent lane change may cause a delay in Smart Cruise Control reaction or may cause Smart Cruise Control to react to a vehicle actually in an adjacent lane. Always drive cautiously to prevent unexpected and sudden situations from occurring.

  • Always be aware of the surroundings and drive safely, even though a warning message does not appear or an audible warning does not sound.

  • If any other system’s warning message appears or warning sound is being generated, Smart Cruise Control warning message may not appear and an audible warning sound may not be generated.

  • You may not hear the warning sound of Forward Collision-Avoidance Assist if the surroundings are noisy.

  • The vehicle manufacturer is not responsible for any traffic violation or accidents caused by the driver.

  • Always set the vehicle speed under the speed limit in your area.

  • Smart Cruise Control may not operate for a few seconds after the vehicle is started or the front view camera or front radar is initialised.

  • You may hear a sound when the brake is controlled by Smart Cruise Control.
