Rear Collision Warning

The Rear Collision Warning (RCW) function can help the driver to avoid being hit by a vehicle approaching from behind.

City Safety

City Safety uses visual, haptic and acoustic signals to alert the driver of any pedestrians, cyclists, large animals and vehicles that appear. The car then brakes automatically unless the driver him/herself acts within a reasonable time.

Emergency brake lights

Emergency brake lights are activated to alert vehicles behind about heavy braking. The function means that the brake light flashes instead of - as in normal braking - shining with a constant glow.
