When ACC is following another vehicle and the driver indicates the intention to overtake by activating the direction indicatorOn left flash only in left-hand-drive car, or right flash in right-hand-drive car., Adaptive Cruise Control helps by accelerating the vehicle towards the vehicle in front before the driver’s vehicle reaches the overtaking lane.
The function then delays reducing speed in order to avoid premature braking when the driver’s car is approaching a slower vehicle.
The function remains active until the driver’s vehicle has cleared the overtaken vehicle.
Be aware that this function can be activated in more situations other than during overtaking, e.g. when a direction indicator is used to indicate a change of lane or exit to another road - the car will then accelerate briefly.
Starting Overtaking Assistance
The following conditions must exist for Overtaking Assistance to be activated:
- there must be a vehicle in front (the “target vehicle”)
- the speed must be at least 70 km/h (43 mph)
- the stored ACC speed must be high enough for overtaking to take place safely.
Activate the direction indicator.
Use the left direction indicator in a car with the steering wheel on the left, or the right direction indicator in a car with the steering wheel on the right.
Overtaking assistance is started.
When using Overtaking Assistance the driver should be prepared for sudden changes in conditions. In some conditions Overtaking Assistance can cause unwanted acceleration.
Some situations should be avoided for this reason. Examples of such situations are:
- the car is approaching an exit road in order to turn off in the same direction that is normally used for overtaking
- the vehicle in front slows before the driver’s vehicle has entered the overtaking lane
- traffic in the overtaking lane is slowing
- a car designed for right-hand traffic is being driven in a country with left-hand traffic (or vice versa)
Situations of this kind can be avoided by temporarily setting ACC in the standby mode.
